Plastic product automatic screening and processing assembly line and processing method

Abstract

The invention relates to a plastic product automatic screening and processing assembly line and processing method, and belongs to the technical field of plastic recycling. According to the technical scheme, the plastic product automatic screening and processing assembly line is characterized by comprising a main conveying line, wherein a water washing tank is arranged above the feeding end of themain conveying line, a feeding port is formed in the upper part of the water washing tank, a discharging port is formed in the lower part of the water washing tank, and a discharging control assemblyfor controlling discharging of the discharging port is arranged at the discharging port; the main conveying line is sequentially provided with a drying device and a material identification device fromthe feeding end to the discharging end, and a branch conveying line which is perpendicular to the conveying direction of the main conveying line is arranged on the side, close to the discharging endof the main conveying line, of the material identification device; and a feeding assembly is arranged at the feeding end of the branch conveying line. The problem that materials of PVC plastic products and PET plastic products are distinguished by adopting a combustion heat test and the working efficiency is solved, and the PVC plastic products and the PET plastic products can be efficiently and rapidly distinguished and identified.

Description

technical field [0001] The invention relates to the technical field of plastic recycling, in particular to an automatic screening and processing line for plastic products and a processing method. Background technique [0002] With the progress and development of society, more and more attention is paid to the harmonious development of man and nature. The recycling of resources has also gradually received attention, especially paper and plastic products that are often used in daily life. When recycling plastic products, it is necessary to screen the plastic products of different materials, and then separately recycle the plastic products of different materials. PVC and PET are two commonly used materials in plastic products. The appearance and feel of plastic products made of these two materials are very similar and cannot be directly identified. [0003] Now to identify PVC and PET plastics, generally use the combustion test method to identify PVC plastics and PET plastics...

AI Technical Summary

Problems solved by technology

However, when there are many plastic products that need to be distinguished, the efficiency of the combustion test is low, and after the combustion test, the burning position of the plastic product needs to be removed before the plastic product can be recycled.
