Description

A special crushing equipment for recycling high specific strength thermoplastic casing

technical field

The utility model belongs to the technical field of plastic casing recycling equipment, in particular to a special crushing equipment for recycling high specific strength thermoplastic plastic casings.

Background technique

Plastic casings are protective casings applied to the outer surface of home appliances, electronic products, etc. These plastic casings will produce defective products during production, and these discarded defective products can be recycled and processed through a shredder. The plastic casing is pulverized, and the fragments of the casing are made into plastic granules by a granulator, and finally re-injected by an injection molding machine. After secondary use, the production of finished products can be effectively reduced. The structure of the existing pulverizer is relatively simple. When the worker puts the plastic casing into the pulverizer, since the plastic casing is mostly flat, the plastic casing will lie flat on the two pulverizing rollers, and two pulverizing rollers are required. After the rollers are rotated several times, the corners of the plastic casing can be twisted between the two pulverizing rollers to start pulverizing, which greatly reduces the pulverizing efficiency of the pulverizer. Moreover, due to the specific elasticity of the plastic casing itself, when the plastic casing is subjected to a crushing force, fragments of the plastic casing will splash and may hurt nearby operators, so there are certain safety hazards.
