Multistage smashing device for plastic product recycling

Abstract

The invention discloses a multistage smashing device for plastic product recycling, and relates to the technical field of waste recycling. The device includes a screening drum, a spiral packing augerand a smashing box, a fine smashing mechanism and a rough smashing mechanism are arranged in the smashing box, the rough smashing mechanism includes a smashing drum and a cutting plate, taper nails are fixedly arranged on the circumferential side face of the smashing drum, and a plurality of triangular blades are fixedly arranged on the surface of a cutting plate I. The fine smashing mechanism includes a second round rod, a cam, a single blade, and a connecting block, a plurality of cross-shaped blades are fixedly arranged on the circumferential side face of the second round rod, a long shaftand a short shaft are fixedly arranged on two sides of the single blade respectively, and the long shaft and the short shaft are separately connected with the connecting block in a rotating mode. According to the device, the rough smashing mechanism, fine smashing mechanism, the screening drum and the spiral packing auger are arranged, unqualified plastic bottle pieces are screened and broken again until pieces are qualified by multiple smashing of plastic bottle pieces with different volume, the problem that the slow speed and the poor effect of smashing plastic bottles by an existing smashing device is solved.

Description

technical field [0001] The invention belongs to the technical field of waste recycling, in particular to a multistage crushing device for recycling plastic products. Background technique [0002] Plastic bottles are mainly used as packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc. Plastic bottles are not easy to break, low in cost, high in transparency, and food-grade raw materials. Waste plastic bottles after use are generally It can be recycled and reused, thereby reducing environmental pollution. In the recycling process of waste plastic bottles, it is necessary to go through a crushing process to obtain the required waste plastic bottle pieces. At present, in the process of crushing plastic bottles, the plastic bottles are generally compressed first, Then the compressed plastic bottle is crushed, but the volume of the compressed plastic bottle is still large, which is not conducive to the contact be...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-stage crushing device for recycling plastic products. By setting a crushing box, a coarse crushing mechanism, a fine crushing mechanism, a screening cylinder and an auger, the plastic bottles can be roughly crushed while being compressed, and then crushed. The plastic bottle flakes that have been crushed many times are screened, and finally the unqualified plastic bottle flakes are crushed again until they are qualified, which solves the problem that the existing crushing device crushes plastic bottles at a slow speed and poor effect
