Intermediate speed grinder

Abstract

The invention discloses an intermediate speed grinder, which has a simple structure and is rational in design. The intermediate speed grinder comprises a base and a middle seat arranged on the base, wherein the top of the middle seat is connected to a hopper; the bottom of the middle seat is connected with a lower hopper; the middle seat comprises a middle seat wall plate, a rolling shaft, cutter holders, movable cutters, fixed cutters and a motor; the motor is fixed on one side outside the middle seat wall plate; the rolling shaft is connected to a motor shaft of the motor; the rolling shaft is arranged in the middle seat wall plate; a plurality of movable cutter holders are sleeved at the periphery of the rolling shaft; the movable cutters are fixed on the movable cutter seats; the fixed cutters are arranged on two side walls in the middle seat wall plate; the movable cutters are tangent to the fixed cutters; a connecting rod is arranged at the bottom of a case and has an eccentric structure; and a screen is arranged between the connecting rod and the movable cutter seats. The intermediate speed grinder is low in cost, can grind materials thoroughly and is easy to clean, the labor intensity of operation workers is reduced, the working efficiency is effectively improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of plastic machinery, in particular to a medium-speed pulverizer for pulverizing plastic waste. Background technique [0002] At present, shredders are widely used, and various waste plastics or plastic packaging can be seen everywhere, polluting the environment, and are non-degradable, causing great harm. Whether it is urban daily garbage disposal or recycling of waste plastics, it is quite common. The key step in the recycling of waste plastics is to crush them into particle sizes suitable for reprocessing, so there are various types of waste plastic shredders. [0003] Existing plastic shredders generally cut and shred plastics by rotating a roller milling cutter. This type of equipment generally has a complex structure, low production efficiency, high labor intensity for workers, and unsatisfactory shredding results. Some machines are used to crush the waste discharged from the injection molding machine. Since th...

Problems solved by technology

[0003] Existing plastic pulverizers generally use the rotary milling cutter to cut and pulverize the plastic. This type of equipment generally has a complex structure, low production efficiency, high labor intensity for workers, and unsatisfactory pulverization results.

Some machines are used to crush the waste discharged from the injection molding machine. Since the square chassis of this kind of machinery is a fixed structure, when it is necessary to clean the inside of the chassis or maintain the knife shaft, it is necessary to take out the knife shaft, which is time-consuming and laborious. Affect work efficiency

[0004] In addition, the connection between the motor and the rotating shaft in the crushing chamber is a vertical connection, and multiple components are required for transmission between the motor and the rotating shaft, resulting in high cost
