Waste plastic recycling system

Abstract

The invention discloses a waste plastic recycling system. The waste plastic recycling system comprises a breaking device, a mixing device, a hot melting device, an injection molding device, a feedingchamber and an impurity removal component, wherein the breaking device is used for breaking waste plastics; the mixing device is used for uniformly mixing the broken waste plastics with ABS plastics;the hot melting device is used for melting and plasticizing mixed plastic raw materials; the feeding chamber is used for conveying the melted and plasticized plastic raw materials to the injection molding device for injection molding; and the impurity removal component is arranged in the feeding chamber, and is used for filtering the materials conveyed by the feeding chamber to remove impurities in the plastic raw materials. The impurities in the melted plastics can be filtered and removed, the circumstance that impurities exist in the product after injection molding is avoided effectively, and it ensures that the product obtained by injection molding has good quality; and secondarily, the impurity removal component is arranged in the feeding chamber, in a feeding process, the impurities of the melted plastics can be removed, the processing time is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of resource recycling, and in particular relates to a waste plastic recycling system. Background technique [0002] In order to store more for a long time, there have been many handicrafts made of plastics in the prior art. Secondly, in order to improve the utilization rate of resources, it has begun to reprocess waste plastics and waste plastic handicrafts to prepare new handicrafts, so as to reduce the waste of resources. The existing treatment of waste plastic waste is usually: crushing waste plastics and mixing them with ABS plastic raw materials for injection molding, so as to reduce the use of ABS plastic raw materials in the injection molding process and reduce the waste of resources. [0003] In this way, there are usually more impurities in waste plastics, and some fine impurities have not been removed in the previous screening and crushing process, and then after being mixed with ABS plastic raw m...

AI Technical Summary

Problems solved by technology

[0003] In this way, there are usually more impurities in waste plastics, and some fine impurities have not been removed in the previous screening and crushing process, and then after being mixed with ABS plastic raw materials and melted, the molten plastic raw materials It is easy to have impurities, which will affect the quality of handicrafts obtained by injection molding
