Defective product crushing and recycling equipment for foamed plastic products

Abstract

The invention relates to the technical field of foamed plastic reprocessing, and discloses defective crushing and recycling equipment for foamed plastic products. The defective crushing and recycling equipment comprises a crushing disc and a feeding pipe, a bearing disc is arranged on the outer side of the bottom end of the crushing disc, sliding plates in an annular array are slidably embedded in the bearing disc, a plurality of first sliding rods which are arranged in an annular array mode are embedded in the inner side of the bottom end of the crushing disc in a sliding mode, a plurality of second clamping teeth are evenly distributed on one side of each first sliding rod, and a material suction groove is formed between every two adjacent first sliding rods. According to the scheme, through the mode that the crushing disc is matched with the bearing disc, foamed plastic is crushed in a gap between the crushing disc and the bearing disc, the foamed plastic is pushed by the sliding plates in the bearing disc, under the action of a plurality of sets of second clamping teeth, the foamed plastic is decomposed conveniently, the rotating speed of the crushing disc is controlled to change the distance of the second clamping teeth protruding out of the crushing disc, so that crushing effects of different degrees are obtained, and the applicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of reprocessing of foamed plastics, in particular to a crushing and recycling equipment for defective foamed plastics products. Background technique [0002] Foam plastic is a kind of polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and its dielectric properties are better than that of matrix resin. It is widely used; almost All kinds of plastics can be made into foamed plastics, and foam molding has become an important field in plastics processing. [0003] When the existing foam plastics are crushed, the crushing operation of the foam is mostly carried out by crushing rollers or cutters. Due to the short contact time between the crushing rollers and cutters and the foam, the crushing effect of the foam is not good, and some foams cannot be obtained. More detailed decompositio...

AI Technical Summary

Problems solved by technology

[0003] When the existing foam plastics are crushed, the crushing operation of the foam is mostly carried out by crushing rollers or cutters. Due to the contact time between the crushing rollers and cutters and the foam Shorter, resulting in poor crushing effect of the foam, some foams cannot be decomposed in a more detailed manner, and because the existing foam crushing device lacks a mechanism for forcing the foam to flow, the crushed foam is flying around, and the static electricity Adhesion to the inner wall of the machine under the action will affect the surrounding environment and have a certain degree of impact on the machine

[0004] In view of the related technologies mentioned above, the inventor believes that the existing foam plastic crushing device has the defect of poor decomposition effect
