Multistage plastic crusher

Abstract

The invention discloses a multistage plastic crusher. The multistage plastic crusher comprises a housing, wherein a cavity is formed in the lower end of the housing; a rotating shaft is arranged at the top end of the inner part of the cavity; a telescopic device is arranged at the lower end of the rotating shaft; a movable plate is arranged at the lower end of the telescopic device; a positioning column is arranged on the lower side of the movable plate; universal wheels are further arranged on four corners at the lower end of the housing; a motor is arranged at the upper end of the housing; a bearing is arranged at the output end of the motor; a crushing shaft extending into the housing is connected to the bearing; a plurality of crushing knives are arranged on the outer side of the crushing shaft; a first filter screen, a second filter screen and a third filter screen are sequentially arranged in the housing from top to bottom; temperature sensors are separately arranged on the motor, the bearing and the crushing shaft; a control device is arranged at the upper end of the housing; an alarm is arranged at the upper end of the control device; and a wireless sending module is also arranged on the control device. The multistage plastic crusher disclosed by the invention is simple in structure, convenient to use, high in safety, convenient to move, firm to fix and good in crushing effect.

Description

Technical field [0001] The invention relates to the technical field of plastic crushing devices, in particular to a multi-stage plastic crusher. Background technique [0002] With the development of the plastics industry, plastic products are widely used in industry, agriculture and people's daily lives, and a large number of waste plastics have followed. How to properly dispose of these waste plastics and reduce their impact on the environment is an urgent problem to be solved, and it is also a requirement for building a conservation-oriented society. The emergence of plastic shredders provides a good idea to solve this problem. The plastic shredder is used to crush waste plastics, scraps, plastic shells, plastic films and other plastic recycling, and can be used for secondary use of plastic products. However, when the grinder is working under a long load, the temperature of the grinder motor or the body is too high, which will affect the service life of the body parts and dir...

AI Technical Summary

Problems solved by technology

However, when the pulverizer works under load for a long time, the temperature of the motor or body of the pulverizer is too high, which will affect the service life of the parts of the machine, directly affect the normal operation and production efficiency of the equipment, and secondly, some hot-melt materials are easy to Adhesion, but the inner wall is easy to adhere to the material, resulting in blockage

At present, there is no relevant temperature detection device installed on the plastic pulverizer to monitor the temperature of its body or bearings in real time
