How to repair the metal baler after failure

The application of metal baler is very extensive, it is precisely because of its overload work, so under the long-term high-intensity work of the equipment, the occurrence of failure is inevitable. Many times, our equipment manuals will show our numerical range. At this time, please make sure that this value is normally in the laboratory environment. Your working environment is not the same as the laboratory environment, so the actual If you do not strictly follow the operation procedures of the metal baler during the operation, the chance of equipment failure will be greater.

Before disassembling the hydraulic cylinder of the metal baler, the pressure should be relieved by the gear oil circuit. Otherwise, when the connector connected to the hydraulic cylinder is unscrewed, the high-pressure oil in the return fuel pipe will be ejected. When the control circuit of the hydraulic machine is relieved of pressure, it is necessary to unscrew the handle of the governor valve or the pressure-changing screw to make the working pressure oil throw up, and then disconnect the switching power supply or energy source, so that the hydraulic control valve stops running.

When disassembling, the external thread on the top of the piston, the external thread on the oil hole, the surface of the piston and the inner cavity of the cylinder liner should be avoided. In order to avoid bending or deformation of fine parts such as pistons, the supporting points of the pads should be balanced when placed.

The disassembly and assembly of the hydraulic cylinder of the metal baler should be carried out in a clean and clean natural environment to avoid environmental pollution by the surrounding dust, residue and other wastes. The disassembled parts shall be subjected to anti-fouling maintenance.

Before disassembling the hydraulic cylinder of the metal baler, the hydraulic oil in the two chambers of the hydraulic cylinder should be drained.

After disassembling and assembling, the metal baler should be carefully inspected to determine what parts can be used again and what parts should be repaired.

The disassembly and assembly of metal baler should be carried out in order. Because various hydraulic cylinders have different methods, the disassembly order is also slightly different. Generally, the cylinder head should be disassembled first, and then the piston rod and piston should be disassembled. When disassembling the cylinder head of the hydraulic cylinder, tools should be used for the snap keys or ductile flat washers of the internal snap connection. Flat shovel is strictly prohibited: for flanged bearing end caps, it must be shot with screws, and no hammering Hard pry. When the piston rod and piston cannot be drawn out, it is not necessary to force it out, and the disassembly and assembly must be carried out for the sake of reason, and the forceful operation will cause scratches.

Briefly describe the lubrication requirements of metal baler parts

The metal baler is more practical for the packaging of various products, especially those powder and granule materials with greater fluidity. If you want to obtain a good packaging quality, there is also a basic condition that all the organizations of the metal baler are To insist on outstanding smoothness. So, what should be paid special attention to when performing smooth operations on components?

An oil gauge is installed in the box part of the metal baler. Before the equipment is started, it is necessary to add smooth oil once. During the working process of the baler, if it is found that the bearing temperature is increased or the work is not working well, it is necessary to add an appropriate amount of smooth oil. Inside the hydraulic baler, it is necessary to store the organization for a long time, and the height of the oil level is based on the principle that the worm gear completely invades the oil, and the new oil must also be replaced regularly.

When refueling the metal baler, do not let the oil overflow the cup, let it not flow around the machine and the ground, to avoid the formation of pollution and affect the quality of related products. In short, the metal baler not only needs to be refueled, but also refueling, in order to get a greater effect of its effectiveness.

The operation method of the plastic granulator mainly includes a series of stages such as the installation, control, trial operation, operation method, maintenance and repair of the machine equipment. When using the plastic granulator, it is necessary to pay attention to its characteristics.

Preparation of the operation method of plastic granulator.

Used for extrusion molding. Raw materials should meet the required dryness standards, and further dryness needs to be done if necessary. The raw materials are sieved to remove agglomerated particles and mechanical debris.

When operating the plastic granulator, check that the raw water, electricity, and gas systems of the equipment are all normal, and ensure that the water and gas lines are unobstructed and leak-free. Is the electrical equipment system all normal? The electric heating system, temperature control system, several types Whether the electronic instrument is safe and reliable at work; the auxiliary machine runs at a slow speed to check whether the machine equipment is running normally; turn on the mechanical pump of the setting table to check whether it is normal at work; several machine equipment are lubricated and lubricated. Solve problems in a timely manner if found. Install the machine head and shaped sleeve. According to the type of products, specifications and models, choose the specifications of the machine head. Install the machine head in the following order.

Operation of plastic granulator operation method

You can drive after temperature control. Before driving, tighten the screw of the machine head and the flange of the plastic granulator-once to eliminate the difference between the thermal expansion of the screw and the machine head. The order of tightening the screw of the machine head is diagonal Tight, evenly distributed. When tightening the flange nut of the machine head, the standard is tight around, otherwise, it is necessary to run the material.

When operating the plastic granulator, select the "Ready to Drive" button, then connect the "Drive" button, then slowly turn the screw of the extruder

Speed ​​control knob, the screw speed of the extruder is turned on slowly. After that, it gradually accelerated, and at the same time, a small amount of material was fed. When feeding, pay close attention to the change of the host's current meter and the prompts of several kinds of tips. The screw torque of the extruder cannot exceed the red mark.

When operating the plastic granulator, before the material profile is squeezed, no one is allowed to stand directly in front of the die, so as to avoid accidents due to screw breakage or raw material wetting and foaming. After the material is extruded from the die of the machine head, it is necessary to slowly cool the extrudate and lead it to the traction device and the shaping die, and activate these devices. Then follow the prompt value of the control electronic instrument and the standard for extruded plastic products. Each part shall be controlled accordingly, so that the whole extrusion operation method can meet all normal conditions. And add enough material according to the demand, the operation method of the twin screw plastic granulator adopts the metering feeder to distribute the material at a uniform speed. There are heavy mechanical parts in the assembly and disassembly of the machine head and the screw of the extruder. 5 safety matters to be noted when operating the plastic granulator are: electricity, heat, rotation of mechanical equipment, and loading and unloading of heavy mechanical parts. Plastic granulator workshop must be equipped with lifting machine equipment. To ensure safe production.

The key points of the operation method of the plastic granulator are different but have the same points. Plastic machinery industry information for you

Briefly introduce the operation method of the same points when extruding several plastic products and the key points of the operation method of the plastic granulator.

Startup for operation of granulator equipment

Most can be distinguished from the surface of the extruded material. 3 When the material is discharged uniformly and the plastic is better, it can be used to pull the man to set the sleeve. The distinction between plasticized conditions depends on technical experience. That is, the surface is shiny, no impurities, no foaming, scorching material and discoloration. The extruded incoming material is squeezed by hand to a certain degree without burrs and cracks, and has a certain elasticity. At this time, the material is plasticized better. If the plasticization is poor, the screw rotation speed of the extruder, the working temperature of the barrel and the screen changer should be adjusted appropriately until it meets the requirements. It should be regularly checked according to the requirements of the equipment whether the data of the mechanical equipment is normal. 4 During the operation of the granulator equipment. And fill in the equipment record sheet. Check the quality of the granule products according to the product quality inspection technical specifications, and take measures to solve the problems in time.

Shutdown of granulator equipment operation

The remaining material in the granulator equipment is squeezed out. 1 The operation of the granulator equipment is used to stop feeding. When the screw of the extruder is exposed, turn off the power of the barrel and screen changer to stop heating. Stop the screw and auxiliary machine of the extruder. 2 Turn off the power of the granulator equipment and auxiliary machines. Clean the screen changer. Clean the outlet of the screen board and screen changer. In order to prevent damage to the inner surface of the screen changer during cleaning, 3 disassemble the connection flange of the screen changer. The remaining material in the screen changer should be cleaned with a steel rule and steel sheet, and then the remaining material stuck in the screen changer should be removed with sandpaper, polished, and coated with engine oil or hydraulic oil to prevent rust. After removing the screen changer, clean the screw and barrel of the 4 extruder. Reopen the host machine, add stop material (or through the crushed material) to clean the screw and barrel of the extruder. At this time, the screw of the extruder uses low speed to reduce screw wear. After the shutdown material is ground into a powder and completely extruded, you can use compressed air to continuously blow out the residual granules and powder from the feed port and exhaust port until the barrel is ensured that there is no residual material. To zero, stop the granulator equipment, turn off the main switch power supply and cold water main valve.

How to maintain plastic granulator

It should be noted that maintenance and repair are equally critical tasks. Maintenance is a protective measure against the wear and damage of machine equipment parts. Repair and replacement of parts are a necessary means to ensure that all production and manufacturing are properly done, so that machine equipment can exert its original performance. These two tasks should be well combined to prevent dominance and prevent it from happening. Before the parts of the machinery and equipment are damaged and cannot be operated, they should be repaired and replaced in time to ensure that the machinery and equipment have a long-term good operating state.

Preparations before starting the plastic granulator Clean the sanitary environment around the extruder, clean the extruder, and the attached machinery and equipment. Carefully study the safe operation rules of the extruder, understand and understand the function and function of each part and component in the structural characteristics of the machine equipment, and memorize the function and usage of each switch and button. Check whether the nuts on the device are loose. Check that the safety guards are strong. Check that the installation of the V-belt is tight and properly adjusted. Move the V-belt, the rotation should be relatively easy, and the screw of the extruder rotates without clamping. Check the rotation direction of the extruder screw. Check towards the barrel mouth. If the screw thread of the extruder is right-handed, the rotation direction of the extruder screw should be clockwise. Check whether the protective grounding of the equipment and control cabinet is tightened.
