Description

Technical Field

[0002] Plastic particles have a wide range of applications. In daily life, recycled particles can be used to make various plastic bags, buckets, basins, toys, furniture, stationery and other daily necessities and various plastic products. When plastic particles are used as raw materials to produce other plastic products, they need to be crushed first, so a crushing processing device is needed. After searching, a plastic particle multi-stage crushing processing device disclosed by application number CN202220415494.X records that the plastic particles are slightly heated by a heater to soften them, the electric push rod extends to the left to push the plastic particles, and the plastic particles are squeezed under the action of the left vertical partition.
