Causes the plastic pelletizing machine to stop instantaneously

The reason why the plastic pelletizing machine mainframe does not roll or stop suddenly causes the fault to be caused by the power of the main motor is not turned on, or the heating time is high, or one of the heaters does not work, causing the torque to be too large and the motor is overloaded. . The fault is handled by checking whether the host circuit is turned on, turning on the power; checking the temperature display of each segment, confirming the warm-up temperature rise time, checking each heater for damage or poor contact, and eliminating it.


  The main pelletizing machine of the plastic pelletizing machine rolls, but the screw does not turn to cause the failure: the transmission V has a loose bandwidth, wear and slip; or the safety button loosely falls off or disconnects.

  This fault is handled by adjusting the V-belt center distance, tightening the belt, or replacing the new V-belt; checking the safety key, analyzing the cause of the break, and replacing the safety key.

  The plastic pelletizing machine screw runs normally, but the reason for the failure is that the hopper feed is not continuous; or the feed port is blocked by foreign matter; or "bridge" occurs, or the metal is dropped into the groove The hard object blocks the screw groove and cannot be fed normally; the treatment of this fault: increase the feeding amount so that the screw feeding is continuous and not disordered; stop the inspection to remove the foreign matter in the material port to eliminate the "bridge" phenomenon; if it is confirmed that the metal foreign matter falls into the snail The screw should be stopped immediately to disassemble the screw to remove metal foreign matter.
