[0002] PVC was once the world's most produced general-purpose plastic, with a wide range of applications. PVC comes in two varieties: rigid (sometimes abbreviated as RPVC) and flexible. Rigid PVC is used in building pipes, doors, and windows. It is also used in plastic bottles, packaging, and bank and membership cards. Adding plasticizers can make PVC softer and more flexible. It is used in pipes, cable insulation, flooring, signs, phonograph records, inflatable products, and as a rubber substitute.

[0003] In the PVC plastic processing process, in order to turn PVC plastic waste into smaller particles, which is conducive to subsequent treatment and recycling, the PVC plastic waste needs to be crushed.

[0031] By setting up the screening mechanism 6, impurities and foreign matter in the PVC plastic waste, such as metal, glass, etc., can be removed, thereby protecting the crushing equipment and extending the service life of the equipment. Secondly, the crushed PVC plastic waste can be classified according to different particle sizes to improve the quality and utilization rate of the recycled material. In addition, screening can realize the graded treatment of the crushed material, making it more suitable for different recycling or processing needs, improving production efficiency and economic benefits. Finally, screening can reduce the uncrushed or unprocessed garbage residues, which is beneficial to environmental protection and resource recycling.

[0032] Example 2

[0033] In one embodiment, a protective cover 7 is fixedly connected to the front and rear sides of the surface of the crushing box 1, and the weight block 603 is located on the inner side of the protective cover 7. A motor cover 8 is fixedly installed on the rear side of the surface of the crushing box 1, and the servo motor 3 is located on the inner side of the motor cover 8. Guide grooves 15 are provided on the front and rear sides of the inner cavity of the connecting block 604, and the baffle 606 is fixedly installed with a guide block 9, which is slidably connected to the inner side of the guide groove 15.
