[0002] Plastic is a material composed of high molecular polymers, usually made from petrochemical products. Plastic raw materials are usually crushed during the processing process. By crushing, large pieces or unformed plastic materials can be processed into granular materials suitable for subsequent molding or reprocessing. This pretreatment process helps to improve the uniformity and processing performance of the plastic.

[0032] The anti-blocking crushing assembly 3 is arranged inside the crushing box 1, and includes a motor 301 installed on the upper surface of the crushing box 1, a rotating rod 302 arranged on the output shaft of the motor 301 and extending to the inside of the crushing box 1, and a crushing anti-blocking structure arranged outside the rotating rod 302. The crushing anti-blocking structure of the anti-blocking crushing assembly 3 includes a sieve plate 303 rotatably connected to the outer surface of the rotating rod 302, and the sieve plate 303 can be used to screen the plastic.

[0033] The outer surface of the sieve plate 303 is connected to the inner wall of the crushing box 1, and the outer surface of the rotating rod 302 is fixedly connected to the support rods 304 arranged in a ring. The outer surface of each support rod 304 is fixedly connected to the crushing knives 305 arranged at equal distances, and the outer surface of the rotating rod 302 is fixedly connected to the push plate 306 arranged in a ring. When the motor 301 is working, the support rods 304 will drive the crushing knives 305 to crush the plastic raw materials, and at the same time the push plate 306 will rotate to push the plastic raw materials, allowing the plastic raw materials to flow, and the crushed plastic raw materials can better fall from the sieve plate 303 to avoid accumulation on the sieve plate 303.

[0034] The outer surface of the rotating rod 302 is fixedly connected with a circularly arranged vibration plate 307, and each vibration plate 307 is located below the screen plate 303. The vibration plates 307 can hit the falling plastic raw material to remove dust attached to its surface.

There will be a certain gap between the bottom end of the deflector 5 and the ground, which is convenient for the staff to collect the discharged plastic particles.

[0040] Working principle: When in use, pour the plastic raw material into the hopper 202, and the plastic raw material will fall onto the screen plate 303 along the guide plate 204, then start the motor 301 to work, the motor 301 will drive the rotating rod 302 to rotate, and the support rod 304 will drive the crushing knife 305 to rotate highly to crush the plastic raw material. At the same time, the push plate 306 will rotate to push the crushed and uncrushed raw materials to avoid blockage. The crushed raw material will fall from the screen plate 303, and the dust generated by the crushing will also fall down. The uncrushed raw material will continue to rotate and be crushed by the crushing knife 305. The vibration plate 307 will collect the fallen plastic raw materials when it rotates, and the dust on the surface of the plastic will float into the air. Then start the exhaust fan 402 to work, and the suction pipe 404 will suck the dust into the circular tube 403, and the dust will be discharged from the mounting cylinder 401.
