Plastic film recovery system for paper mill

Abstract

The invention relates to material sorting equipment, in particular to a plastic film recovery system for a paper mill. The plastic film recovery system comprises a frame body, wherein a plurality of first air bags are arranged in a rubber belt; the first air bags are arranged at equal intervals; two sides of each first air bag are provided with first springs fixedly connected to an upper inner wall and a lower inner wall of the rubber belt; at least three extruding wheels are arranged between a first driven wheel and a second driven wheel; each extruding wheel rotates by clinging to an upper surface of the rubber belt; an arrangement distance of the extruding wheels is equal to an arrangement distance of the first air bags; suckers with the number the same as that of the first air bags andpositions corresponding to those of the first air bags are fixedly connected to a surface of the rubber belt; at least three cams are arranged in the frame body; and the cams rotate to be matched with the extruding wheels to extrude the suckers, so that the first air bags are extruded by the rubber belt, and when the first air bags pass by the next cam, as the first air bags are in a compressed state, the first air bags cannot be extruded by the cam, and different suckers can be extruded by a convex position during every revolution of the cam.

Description

technical field [0001] The invention relates to a material selection device, in particular to a plastic film recycling system in a paper mill. Background technique [0002] The development of the plastics industry has brought great benefits to mankind, but it has left endless troubles, namely "white pollution". Since there are plastic products, old plastics are inevitably produced, and as time goes by, more new raw materials are put into use, which makes waste plastics rise sharply. Because waste plastics are not easy to age and degrade at room temperature, white pollution is increasing day by day, causing serious damage to the ecological environment. Among them, the waste generated by paper mills in the production process contains a large amount of plastic films. These plastic films belong to renewable energy and have repeated Utilization value, it can be used as raw material for granulator or made into various plastic products through injection molding machine, but the pr...

Problems solved by technology

[0004] This technical solution uses wind power to classify the garbage according to the quality of the garbage. It cannot guarantee the separation of garbage with the same quality as the plastic film, resulting in too much other garbage collected in the plastic film. It is easy to break up the plastic film by breaking up the material through the separating teeth. Broken, and it is easy to cause other garbage to stick to the film, resulting in incomplete separation
