What is the function of a plastic pelletizer?

Plastic pelletizer is mainly used for processing waste plastic film, woven bags, agricultural convenient bags, basins, daily supplies, etc., suitable for most common waste plastic, waste plastic recycling industry is the most widely used, the most popular users of plastic recycling processing machinery.

The function of plastic pelletizer

Plastic pelletizer adopts a special screw design and different configurations, suitable for the production of PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA and other plastic regeneration and color mixing granulation. The reducer adopts the design of high torque to achieve the performance of smooth operation without noise. Screw, cylinder by special hardening treatment, with wear-resisting, mixing performance is good, high yield characteristics, vacuum exhaust or ordinary exhaust design, can be in the production process of water, waste gas discharged away, the use of more stable, stronger colloidal particles, to ensure the good quality of products.

Troubleshooting of plastic pelletizer

• Screw normal operation, but no discharge

Reason: Hopper feeding discontinuous; There are foreign bodies blocking the feed port or produce "bridging"; The screw groove falls into the metal hard material to block the screw groove, and the feeding can not be normal;

Treatment method: Increase the feeding amount to make the screw feeding continuous and stable; Stop the machine to eliminate the foreign body in the feed mouth to eliminate the "bridge" phenomenon; If it is confirmed that a metal foreign body has fallen into the screw groove, the screw should be stopped immediately to remove the metal foreign body.

• The main engine does not rotate or stop instantly

Reason: The power supply of the main motor is not connected; Insufficient heating time, or one of the heaters does not work, resulting in excessive torque and motor overload.

Treatment method: Check whether the host circuit is connected, connect the power supply; Check the temperature display of each section, confirm the preheating and heating time, check whether the heaters have been damaged or contact bad phenomenon, and eliminate.

• Vent discharge

Reason: Raw material is not clean enough with impurities; The feed speed is too fast to make the screw extrusion unstable; The plasticizing temperature is not enough for screw extrusion.

Treatment method: Clean the raw material and then feed or replace the filter screen; Reduce the feeding amount to make the plasticized stable screw extrusion smoothly; Increase plasticizing temperature (temperature should not be too high, in case of burning plastic, affect the quality of production).

• The main motor rotates, but the screw does not

Reason: Transmission V-belt loose, wear and slip; Safety key loose fall off or disconnect.

Treatment method: Adjust the center distance of the V-belt, tighten the belt, or replace the new V-belt; Check the safety key, analyze the cause of fracture, and replace the safety key.

Plastic pelletizer is only applicable to the company's TPR/EVA/PVC/ masterbatch/no fontanelle cable material/rubber high filling engineering materials and other production line equipment operation guidance. Standardization of plastic pelletizer operation and equipment maintenance, its purpose is to ensure the normal operation of equipment and prolong life, reduce maintenance costs and improve production efficiency.
