Abstract

The invention discloses a plastic grinder. The plastic grinder comprises a machine frame, wherein two grinding rollers are arranged on the machine frame side by side; the grinding rollers are in transmission connection with a driving device; a plurality of rows of grinding teeth are arranged on the grinding rollers; a feed port of the machine frame is formed above the grinding rollers; a discharge port is formed below the grinding rollers; a feed squeezer, namely a spiral feeder is arranged at the tail end of the feed port; the plurality of rows of grinding teeth are spirally arranged on the external circumference of the grinding rollers; and the grinding teeth on the two grinding rollers are mutually staggered. Due to the adoption of the technical scheme, plastic is squeezed by the spiral feeder before being fed into the feed port, so that the grinding effect is better after the plastic is fed into the grinder.

Description

technical field [0001] The invention relates to a plastic pulverizer. Background technique [0002] The plastic shredder crushes all kinds of plastic plastics and rubber such as plastic profiles, pipes, rods, silk threads, films, and waste rubber products. The pellets can be directly extruded as raw materials for production. It is suitable for the recycling of plastics such as boxes, thin pipes, blow moldings, bottles, and shells. In the production of plastics, many production raw materials come from the plastic particles crushed by the pulverizer. The existing pulverizers are directly fed from the hopper for pulverization. Since many waste plastics come from different sources, and the sizes and structures are also different, direct feeding affects the pulverization effect of the plastic pulverizer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plastic shredder to improve the shredding effect of plastics. ...
