With the growing popularity of the plastic recycling industry, the application of the plastic granulator machine (also known as the plastic pelletizing machine) is increasing rapidly. During daily use, waste plastic pelletizer machine users may encounter some glitches. This requires timely analysis of the cause and troubleshooting. Here is an explanation of its common faults and solutions.

塑料造粒机简介

塑料造粒设备也称为废塑料造粒机。作为塑料薄膜回收生产线中最重要的机器，它通常用于塑料回收工厂。塑料造粒机具有节能、高效、性能稳定、操作简单和易于维护的特点。

5种常见故障及排除方法

以下是塑料颗粒制造机的一般问题及相应解决方案。希望以下内容能在您使用塑料颗粒制造机时有所帮助。

1. 塑料造粒机的主电机不转动或瞬间停机

  • Reasons: unstable power supply voltage or poor contact; insufficient heater heating or a heater does not work, which makes the motor overload due to excessive torque
  • Treatment methods: check the main motor circuit connection of the plastic granulator machine; check the temperature display of each section of the heater, and check whether the heater has poor contact or damage.

2. 塑料造粒机的主电机转动，但螺杆不转动。

  • Causes: The transmission V belt becomes loose, wears and slips; or the safety key becomes loose or disconnected.
  • Troubleshooting methods: adjust the center distance of the V-belt, tighten the belt, or replace with a new V-belt; check the safety key, analyze the cause of the break, and replace the safety key.

3. 颗粒机的螺杆正常运行，但不排出物料

  • Reasons: the feeding of the hopper is not continuous; or there is a foreign object blocking the feeding port; or a metal hard object falls into the screw groove to block the screw groove, and the material cannot be fed normally.
  • Solutions: The troubleshooting method of this failure: increase the feed volume to keep the screw feeding continuously; stop the machine to check and remove the foreign matter in the feed port. If it is confirmed that there is a metal foreign body falling into the screw groove, stop the machine immediately to remove the screw and remove the metal foreign body.

4. 塑料颗粒机导致通风口脱落物料

  • Causes: there are impurities in the raw materials, or the feed speed is too fast to make the screw extrusion unstable, or the plasticization temperature is not enough.
  • Treatment method: clean the raw materials before feeding or replace the filter screen, or reduce the feeding amount to make the screw extrude smoothly, or increase the plasticizing temperature. However, the temperature should not be too high to prevent burns to the plastic and affect the quality of production.

5. 主电机扭矩过低

  • Reasons: the feed system failure caused the twin-screw idling.
  • Solution measures: Check whether the additive system or the main material feeding system is faulty, and clean the blockage of the plastic granulator.

总之，需要及时分析故障，并采取合理措施，以确保塑料回收造粒机的正常运行。
