High-safety plastic crusher

Abstract

The invention discloses a high-safety plastic crusher. The high-safety plastic crusher comprises a rack, wherein a crushing box body is fixedly arranged on the rack; a crushing main shaft is rotatablymounted in the crushing box; a plurality of crushing movable knives are fixedly mounted in the peripheral direction of the crushing main shaft; two fixed knife mounting tables are arranged in the crushing box; each fixed knife mounting table is fixedly equipped with a crushing fixed knife; a crushing sieve is fixedly arranged in the crushing box; the upper end of the crushing box is equipped witha feeding machine head in a hinged mode; a hinged connecting device and a fixed connecting device are arranged between the crushing box and the feeding machine head; a machine head opening and closing device is connected between the rack and the feeding machine head; and a fixed knife regulating device is arranged between each fixed knife mounting table and each crushing fixed knife. Through thehinged type feeding machine head, opening-closing is more convenient, a great deal of labor power and equipment assistance is reduced, operation safety is remarkably improved, and the hinged structureis simple and reliable.

Description

technical field [0001] The invention relates to a plastic pulverizer, in particular to a high-safety plastic pulverizer. Background technique [0002] The plastic shredder is a device that regenerates and recycles plastics after crushing waste plastics and factory plastic scraps. The equipment mainly includes a crushing mechanism. The crushing box is equipped with a rotating and fixed crushing knife and a fixed crushing knife in the crushing box, and the crushing of plastics is realized through the cutting action of the crushing movable knife and the crushing fixed knife. [0003] There are many safety problems in the use of plastic pulverizers: (1) The feeding mechanism is usually a machine head set as a whole, and the machine head is fixedly connected to the crushing box through the structure of boom bolts and boom nuts; When maintaining other structures, it is often necessary to disassemble the machine head as a whole. As the machine head welded by steel plates and the s...

Problems solved by technology

[0003] There are many safety problems in the use of plastic pulverizers: (1) The feeding mechanism is usually a machine head set as a whole, and the machine head is fixedly connected to the crushing box through the structure of boom bolts and boom nuts; When maintaining other structures, it is often necessary to disassemble the machine head as a whole. As the machine head welded by steel plates and the size used as engineering equipment, the weight of the machine head is very large. Multi-manpower assistance and equipment assistance, such as driving auxiliary hoisting, human-assisted alignment installation, etc., have low work efficiency and are likely to cause injury to the staff; (2) Because the blade is used for cutting and crushing, the rotation speed of the crushing knife is very high , so in the plastic crushing process will be accompanied by a large amount of plastic splash, the splash is characterized by the direction is not fixed and the splash speed is high, the splashed plastic is easy to fly out from the feed port on the machine head, causing the splash to injure the staff, although now There are measures to add a splash screen at the feed inlet, but the effect is not satisfactory
