Vertical plastic crushing machine

Abstract

The invention discloses a vertical plastic crushing machine, and belongs to the technical field of environmental protection equipment. The vertical plastic crushing machine solves the problems that acutter of an existing plastic crushing device is difficult to replace when damaged, cleaning is inconvenient and the sizes of crushed particles are not uniform. The vertical plastic crushing machine comprises a rotary cutter assembling unit, a primary crushing mechanism, a rotary motor, a shell, air inlet equipment, a feeding hopper, a conveying device, a baffle, a sieve plate, a spring and a trolley. The rotary cutter assembling unit is arranged in the shell, the distance between the cutter on the rotary cutter assembly and the inner wall of the shell is gradually reduced from top to bottom,and multi-stage crushing is carried out; and the primary crushing mechanism can preliminarily crush plastic conveyed into the feeding hopper by the conveying device, the temperature in the shell is effectively reduced due to the arrangement of the air inlet equipment, the plastic adhesion caused by too high temperature rise is prevented, and a cleaning function is also achieved. The vertical plastic crushing machine has the advantages that the cutter is easy to replace, cleaning is facilitated, cutting is uniform and discharging is smooth, and has high practicability.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a vertical plastic pulverizer. Background technique [0002] Plastic crushing refers to the use of a certain recycling process to crush waste plastics and then recycle them to achieve the purpose of turning waste into treasure. Plastic crushing and recycling not only effectively solves the problem of plastic pollution, but also saves raw materials. It has formed a green and environmentally friendly industry and has been strongly advocated by the country. [0003] Existing plastic shredders crush plastics mainly through the impact, extrusion and shredding of the blades on the main shaft and the crushing chamber. Usually, the blades are welded on the main shaft. As the frequency of use increases, the knives cannot The avoidance will cause wear and tear, resulting in poor crushing effect. Since the cutter is welded on the spindle, it takes tim...
