Plastic pellet cutting machine, also known as plastic granule cutter, is mainly used to process waste plastic film (industrial packaging film, agricultural mulch film, etc.), woven bags, plastic pots, buckets, etc. It is suitable for most common waste plastics. It is a widely used and popular plastic recycling processing machine in the waste plastic recycling industry. It is also one of the most important pieces of equipment for plastic film granulation line.
Plastic pellet cutting machine in application of some problems will inevitably occur, the following will introduce you to three kinds of plastic pellet cutting machine common problems, and the corresponding solution.
Screws are normal operation, can not be discharged
Reason
- Hopper feeding of the plastic strip cutting machine is not continuous.
- Under the mouth of the foreign matter blocked or caused by “cross-linking”.
- Hard metal objects fall into the threaded groove to block the threaded groove, and can not be conveyed normally.
Çözüm
- Increase the feed volume and stabilize the screw feed continuously.
- Remove the foreign matter from the discharge port in the stop for “cross-linking” condition.
- If it is confirmed that a foreign object has fallen into the threaded groove, immediately disassemble the screw to remove the foreign object.
Plastic pellet cutting machine exhaust hole out of the material
Reason
- The raw material is not clean and contains rubbish.
- Debris clogs the filter.
- If the feeding speed is too fast, the screw extrusion will become unstable and the plasticizing temperature is not sufficient.
Çözüm
- Clean the raw material, re-feed and re-feed, or reduce the amount of filter removal and feeding, smooth extrusion, and plasticizing smooth screw.
- Stop the machine to dismantle and replace the mesh, the mesh can be 40–60 mesh.
- Increase the plasticizing temperature.
Plastic pellet cutting machine host does not move or stop instantly
Reason
- The main motor of plastic pellet cutting machine is not connected to the power supply.
- The heating time is not enough, or one of the heaters does not work, the torque is too large, and the motor is overloaded.
Çözüm
- Check whether the power circuit of the main machine of the equipment is connected, and then switch on the machine.
- Check the temperature display information of each section to determine the preheating temperature rise time, check whether each heater is damaged, and exclude poor contact.
