Plastic crusher

Abstract

The invention discloses a plastics disintegrator, comprising a frame, which is characterized in that two crushing rolls are arranged side by side on the frame, the crushing rolls are connected with a power drive unit, a plurality of crushing teeth are arranged on the crushing rolls, a plurality of compartment grooves are arranged between the adjacent crushing teeth, and the crushing teeth are spirally arranged on the external circumference of the crushing rolls and inclined arranged to form 45 degree of angle with the tangent to periphery of the crushing rolls; when using, the waste plastics are squeezed into space between the two crushing rolls, the two crushing rolls are driven to rotate with different velocity ratios, the crushing teeth arranged on the two crushing rolls can tear and break the wasted plastics, create the cleaning condition for plastics and improve the stability of product quality.

Description

technical field [0001] The invention relates to a plastic pulverizer, which belongs to the technical field of plastic pulverization. Background technique [0002] The recycling of waste plastics is quite common at present. The key step in the recycling of waste plastics is to crush them into particle sizes suitable for reprocessing, so various types of waste plastic shredders have appeared. The existing plastic shredders are generally The plastic is cut and crushed by rotating the roller milling cutter or the rotary vane. This type of equipment generally has a complex structure, low production efficiency, and the crushing results are not ideal, especially for crushing tubular plastics. The crushing is not thorough. After the tubular plastic is crushed, there is adhesion. During the cleaning process, the sediment and other dirt in the tube cannot be cleaned out, which eventually leads to more impurities in the granulated product, which affects the stability of product quality...

[0002] The recycling of waste plastics is quite common at present. The key step in the recycling of waste plastics is to crush them into particle sizes suitable for reprocessing, so various types of waste plastic shredders have appeared. The existing plastic shredders generally The plastic is cut and crushed by rotating the roller milling cutter or the rotary blade. This type of equipment generally has a complex structure, low production efficiency, and the crushing results are not ideal, especially for crushing tubular plastics. The crushing is not complete. After the tubular plastic is crushed, there is adhesion. During the cleaning process, the sediment and other dirt in the tube cannot be cleaned out, which will eventually lead to more impurities in the granulated product, which will affect the stability of product quality.
