[0002] A large number of plastic products used in our daily production and life are mainly made of plastic as raw materials through processing. Plastic products not only have stable performance but also have high specific strength. Plastic particles are the raw materials for the production of plastic products. During the production process, some impurities will be mixed in the plastic particles, which need to be screened, otherwise it will affect the quality of plastic particle products.
[0003] When people screen plastic particles, they usually add a large number of plastic particles into the screening cylinder at one time. In this way, the plastic particles will accumulate in the screening cylinder, resulting in a slower rate of plastic particles being fed out of the mesh, thereby reducing the screening efficiency of the plastic particles. At the same time, some larger particles mixed in the plastic particles will cause blockage of the mesh of the screen plate. Therefore, people need to remove the screen plate and clear it after using it for a period of time. However, in the existing technology, the screen plate is usually fixed with multiple screws, which makes it more troublesome for people to disassemble the screen plate. Utility Model Content
