1 Do a good job in the handover class. The problems and solutions for the equipment in the production of this shift should be observed after taking over the equipment. The production and quality of this shift, precautions, and production tools are handed over to the inventory and records are made.

2 Check carefully after taking over. Product quality, whether the temperature of bearings, gears, motors and lubricating oil in the operating part of the equipment is within the specified temperature. Whether the lubricating oil supply position is correct.

3 Listen carefully to the sound of the screw and the sound of the running parts.

4 Verify that the temperature of each part of the barrel and the head die is within the process temperature range, and whether the cooling water temperature is within the specified range.

5 Check whether the raw materials are miscellaneous, the amount of material stored in the hopper, and no tools or debris around the hopper to avoid accidents caused by falling into the hopper.

6 When the sudden power failure occurs, immediately turn off the main motor, electric heating and feeding system switch. Each speed control knob is adjusted back to zero. When the power is restored, the barrel and the head die are heated and heated. When the temperature is raised to the process temperature, the temperature is kept for more than 30 minutes, and then the screw is turned on to rotate the motor. Check the current meter and screw rotation of the main motor. If the current meter pointer swings beyond the rated current, stop immediately to find the cause (may be low temperature of the barrel), and then drive after the problem is solved.

7 If the production is temporarily stopped, it is not necessary to clean the raw materials in the extruder for the extrusion of the polyolefin raw materials. For extruded PVC raw materials, the raw materials in the screw and barrel must be cleaned. When cleaning, some materials that are not easy to be decomposed can be added, and all the residual materials of PVC can be ejected. Then remove the screw, clean the anti-rust oil, and wrap it vertically. Use copper knives and tools when cleaning the screw and barrel. Do not use a hard knife to scrape the adhesive to avoid scratching the screw barrel.

Plastic extruder screw damage causes and repair methods

The screw of the plastic extruder has an important influence on the plasticization of the material, the quality of the product and the production efficiency. When the screw wear is severe and the output of the plastic extruder is reduced, the maintenance of the screw should be arranged. Below, I will introduce the causes and repair methods of the screw damage of the plastic extruder.
First, the reason for the damage of the screw of the plastic extruder
1. The screw rotates in the barrel, and the friction between the material and the two causes the working surface of the screw and the barrel to wear gradually: the diameter of the screw is gradually reduced, and the diameter of the inner hole of the barrel is gradually increased. Thus, the matching diameter gap between the screw and the barrel increases little with the gradual wear of the two. However, since the resistance of the front head and the splitter plate of the barrel is not changed, this increases the leakage flow when the extruded material advances, that is, the flow of material from the diameter gap to the feed direction increases, and the result is a plastic extruder. Production is declining. This phenomenon causes the residence time of the material in the barrel to increase, causing the material to decompose. If it is polyethylene, the hydrogen chloride gas generated by the decomposition enhances the corrosion of the screw and barrel of the plastic extruder.
2. If there are fillers such as calcium carbonate and glass fiber in the material, it can accelerate the wear of the screw and barrel of the plastic extruder screw.
3. Since the material is not plasticized evenly, or metal foreign matter is mixed into the material, the torque of the screw of the plastic extruder suddenly increases, and the torque exceeds the strength limit of the screw so that the screw is broken. This is unconventional accident damage.
Second, the repair method of the extruder screw
1. The broken screw should be considered according to the actual inner diameter of the barrel, and the outer diameter deviation of the new screw is given according to the normal gap of the barrel.
2. After the surface of the thread with the reduced diameter of the worn screw is treated, the wear-resistant alloy is thermally sprayed and then ground to a size. This method is generally processed and repaired by a professional spray factory, and the cost is still relatively low.
3. Surfacing the wear-resistant alloy on the threaded portion of the worn screw. Depending on the degree of wear of the screw, weld 1 to 2 mm thick and then grind the screw to size. The wear-resistant alloy is composed of materials such as C, Cr, Vi, Co, W, etc., which increases the anti-wear and corrosion resistance of the screw. Professional surfacing plants have a high cost for such processing and are rarely used except for special requirements.
4, repair plastic extruder screw can also be surface hard chrome plating method, chromium is also wear-resistant and corrosion-resistant metal, but the hard chrome layer is easier to fall off.

Heating and cooling method for plastic extruder barrel

Heating and cooling are necessary for the smooth extrusion of plastics. In order to allow the plastic to always be extruded within the temperature range required by its processing, it is generally achieved by heating or cooling the temperature of the material in the barrel of the plastic extruder.

The barrel heating of the plastic extruder is to provide heat for plasticizing the raw materials in the barrel, and the barrel cooling is to prevent the raw material from generating excessive heat during extrusion and friction plasticization to increase the temperature. The alternating use of heat and cooling allows the barrel heat of the plastic extruder screw to be controlled within the process temperature range required for the plasticization of the raw material to ensure the normal continuous production of the plastic extruder machine. The heating mode of the barrel: resistance heating, electric induction heating, heating body heating. There are two types of cooling methods: water cooling and air cooling.

The heating method of shuliy mechanical plastic extruder machine adopts resistance heating method. The heater adopts cast aluminum heater, and the electric resistance wire is put into metal tube and filled with an insulating material such as magnesium oxide to make an electric heating rod, which is bent according to the required shape. And then cast into the aluminum alloy. Its small size, light weight, convenient assembly and disassembly, high heating temperature, long service life, moisture, shock and explosion-proof performance.

The Shuliy mechanical plastic extruder adopts the air-cooling method, mainly adopts air cooling, which is to use the electric blower to supply air, blow the wind to the barrel where the temperature needs to be cooled, take away the heat of the barrel, and make the barrel cool down. However, the cooling rate is slow.

The plastic extruder produced by Shuliy Machinery has the characteristics of simple structure, small thermal shock, no pollution, concentrated wind, high cooling efficiency, convenient installation and maintenance, etc. The quality is superior and widely used.

How is the production of plastic pellet extrusion equipment?

In daily life, we often encounter plastic products, such as rubber and plastic sealing strips, plastic tubes, plastic wires, plastic tubes and so on. These products are either in the extrusion molding process or in the casting process. No matter which molding process is used, most of the production process uses plastic pellets.

So how do plastic pellets come out? First of all, the raw materials of plastics should be adjusted according to the quality of the products. These raw materials include resin powder, oil, calcium powder, recycled plastics, etc. These raw materials are mixed by a kneading machine. The raw materials are thoroughly mixed under the high-speed high-temperature stirring of the kneading machine. When all the raw materials are uniformly mixed, the raw materials can be put into the plastic pellet machine for extrusion.

The plastic pellet machine is a plastic granulator that we often say, and it is a kind of plastic extruder equipment. The raw materials enter the screw barrel of the equipment through the feeding funnel of the plastic extruder to start heating up. As the temperature of the barrel increases, the plastic raw materials begin to plasticizer in the extruder barrel, and the extruder screw rotates to these. The plastic in the molten state is subjected to a series of processing such as shearing, kneading, compression, and exhaust.

Finally, a plurality of cylindrical strips is extruded at the die of the plastic pelletizer. After the strips are cooled by water, the shape is stabilized. We can cut these strip-shaped cylindrical products into ours by the tractor. The particles needed.

The quality of the plastic pellets has a direct relationship with the formulation of the product. At the time of production, we must formulate the formulation according to the quality of the product to be produced. In addition, when the granules are produced, the unsuitable products are usually crushed and then granulated, and the crusher is also indispensable in the plastic granule extrusion line.

Structural composition of plastic extrusion equipment

The role of the plastic extruder is to extrude the product. The basic structure of the plastic extruder is the same regardless of the purpose. First of all, the processing part of the plastic extruder for the raw material is the screw, and the feeding part of the connecting screw belongs to the plastic feeding system.

The feeding funnel of the plastic extruder is designed at the end of the barrel. Before feeding, we must raise the screw of the plastic extruder and feed it when the temperature rises to the value we need. operating. The raw material enters the screw barrel from the feeding funnel, and the raw material is heated by the temperature control system of the extruder. In this process, the screw is continuously rotating at a constant speed, and the screw thread cuts and compresses the raw material. Finally, it will be extruded into the shape of the product we need at the die of the plastic extruder.

During the operation of the equipment, we can see that the plastic extruder must be composed of the part of the raw material processed by the screw, the filling part of the feeding part, and the molding part of the plastic extruder die. In addition, the temperature control part of the equipment is connected to the screw barrel of the extruder. Generally, the plastic extruder heats the raw material through a heating sheet or a heating ring, and then the temperature of the extruder barrel is cooled by the fan when the temperature is too high. That is to say, the heating coil and the fan constitute the temperature control system of the plastic extruder.

In addition, the gearbox that drives the screw to rotate and the motor can be classified as the power part of the device. The entire equipment is supported by the extruder frame and then controlled by the intelligent control system. Any part of the structure of the equipment is very critical, so we must choose carefully when choosing a plastic extruder.

How does the plastic extrusion equipment work?

We know that plastic extruders play an important role in the production of actual plastic products. For example, many products such as sealing strips, plastic tubes, plastic sheets, etc. are extruded by plastic extruders, so plastic extruders are widely used in the production of plastic products. So how does the plastic extruder work? Before production, we first need to heat the plastic extruder barrel, and when the temperature rises to the temperature we need, we can process the plastic that has been refined and opened.

The plastic enters the barrel through the feeding system of the extruder and then is cut, compressed, kneaded and the like by a plastic extruder screw. Finally, it is extruded at the die of the plastic extruder into the shape of the product we need.

During the whole production process, the screw of the plastic extruder is continuously running, and the screw barrel, the plastic, and the screw continuously interact to produce the self-production temperature. Then the temperature of the plastic extruder barrel will gradually increase with the continuous production of the equipment, but the plastic will produce vulcanization in the production of excessive temperature and even cause the plastic to produce scorch, so when we are in production It is necessary to set the temperature control part of the plastic extruder to a maximum temperature. When the temperature of the barrel of the plastic extruder reaches the temperature we set, the temperature control system will automatically deliver cold water to the screw extruder of the plastic extruder. Cooldown. Throughout the production process, the temperature control system and the screw are continuously exchanged information to maintain stable production of the equipment.

When we produce different types of plastics or products, we need to adjust and control the temperature of the equipment according to the specific conditions. The temperature requirements of the equipment are not static. We need to adjust to the actual situation.

What are the components of the plastic extrusion equipment?

Plastic extruders are mainly used as molding equipment for plastic products. Common plastic extruders produce products from plastic sealing strips, plastic wires, plastic tubes, and other products. In addition, the plastic extruder is used for the production of granules of raw materials in addition to the direct extrusion of the product.

What parts does the plastic extruder consist of? Today, we understand the composition of some of these components from the plastic extruder in the production process. First, we need to heat the screw of the plastic extruder before running the plastic extruder. When the temperature rises to the temperature we need, we can feed it in the feeding funnel of the plastic extruder.

The plastic pellets are preheated from the feeding system into the barrel, and then the plasticized plastic is pushed toward the die of the extruder for extrusion as the screw of the extruder rotates. It can be said that the screw extruder screw of the plastic extruder is a part of the processing of the product in the production of the equipment, and it is very important, and the extruder die that connects the screw of the screw belongs to the molding part of the equipment. What shape do we need to extrude? The plastic products are controlled on the mold of the plastic extruder die. The screw requires power support during the rotation process, so the plastic extruder is also equipped with a reducer and a motor to power the entire equipment. In the production of plastic extruders, in addition to heating the equipment just after the start-up, most of the time the temperature control part of the plastic extruder is to control the temperature of the equipment within a certain range.

As the self-production temperature of the equipment is getting higher and higher, we will continue to cool the screw of the plastic extruder screw to ensure the production of the plastic extruder. Therefore, in addition to the temperature control system, the plastic extruder has an intelligent control system that controls the operation of the entire machine. To sum up, the composition of the plastic extruder includes a plastic extruder screw, extruder die, feeding system, plastic extruder temperature control system, reducer, motor, and intelligent control cabinet.

How to choose plastic granule machine

With the rapid development of the plastics industry, while the plastic granule machine helps and the living standard is improved, the environmental problems caused by the increase are also increasing. The plastic granule machine that uses recycled plastic to realize recycling and recycling has developed.

It is very necessary to recycle waste plastics and turn waste into treasure. More and more plastic granule machine manufacturers have grown up in this environment. So many manufacturers, customers with demand should choose high-quality plastic pellets. What about the machine?

The plastic granule machine is mainly divided into three types, one of which is a coal-fired granule machine. The disadvantage is that it has a lot of dust, the temperature is not well controlled, and the quality of the produced plastic granules is unstable, and the advantage is low cost. The second is the old extrusion type pellet machine that uses electricity. Its power consumption is huge, and there is no supporting waste plastic cleaning machine. The raw materials are manually cleaned, and the processing environment is often cross-flowed. The latest energy-saving and environmentally-friendly plastic granule machine is not only environmentally friendly but also consumes low power and is recognized as the industry’s lowest standard.
The environmentally friendly plastic granule machine has a matching waste plastic washing machine, which uses circulating water instead of sewage, which greatly reduces the environmental burden. The new plastic granule machine also enables increased production and benefits. Power saving is the main indicator for the inspection of plastic granule machine equipment. The electricity bill accounts for a large proportion of the pelletizing cost. Therefore, the power saving pellet machine and the old-fashioned pellet machine with electricity consumption bring about two full benefits.

The choice of plastic pellet machine is mainly to choose a manufacturer with a strong scale. The regular granulator manufacturers have strong strength to provide comprehensive after-sales service, and invest heavily in technology research and development and innovation. The equipment of regular manufacturers are all finished and reliable, and their brand and word of mouth can stand the test of time.

ANALYSIS OF COMMON KNOWLEDGE OF GRANULE MACHINE MAINTENANCE

Shuliy is a well-known enterprise that supplies granule machines. In order to let everyone better understand the knowledge related to granule machine, the following article will explain the common knowledge of granule machine maintenance.

a: The grass powder content of the machine in the production of raw materials shall not exceed 50%.

b: The length of the granules is adjusted by moving the position of the cutter above the discharge port.

c: When replacing the particle machine template, the reverse nut should be removed first. There are two symmetrical 8mm screw holes on both sides of the template center hole. You can use the bolt to slowly push out the template. If you feel strenuous, you can hammer the template with a hammer. Then, tap the bolt and prevent the bolt from being broken in the hole.

d: In the case of normal production, the pressure roller bearing must be cleaned once with gasoline or diesel for five days. At the same time, it needs to be filled with high-speed lubricating oil. The gearbox is usually repaired once every six months. The vertical shaft bearing needs to be cleaned once every 7 days, the spindle part works. Must be buttered for eight hours.

e: Before the granule machine is used, stop feeding before stopping. After the material in the silo is processed, add the oily material into the hole of the template to keep the inside of the hole lubricated, so that the plugging will not occur in the next use.
