A plastic particle shredder

Abstract

The invention discloses a plastic particle crushing machine which comprises a cutting machine body. A feeding port is formed in the top end of the cutting machine body. A punched hole is formed in the outer wall of an installing rod. A limiting disc is arranged on the outer side of the installing rod. A limiting rod is arranged on the inner side of the limiting disc. The limiting rod penetrates through the punched hole and is connected with a fixing seat. The limiting rod is in threaded connection with the fixing seat. The left side and the right side of the bottom end inside the cutting machine body are each provided with a rotary shaft. A cutter is arranged outside each rotary shaft. A discharging port is formed in the bottom end of the cutting machine body. According to the plastic particle crushing machine, by pulling a connecting plate towards the inner side, a sliding block is driven by the connecting plate to slide towards the inner side in a sliding groove in a sliding plate, the installing rod is fixed by the limiting rod so that a push rod can be fixed, plastic particles are decelerated through a deceleration plate, the phenomenon that due to the fact that the falling speed of the plastic particles is too high, the cutting effect of the cutters to the plastic particles is poor is effectively avoided, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of plastic particle machinery, in particular to a plastic particle pulverizer. Background technique [0002] In the process of extrusion production technology in plastic processing, the extruder produces the required plastic particles through processes such as stranding and pelletizing. The pelletizing quality of the pelletizer will affect the quality of the product. This is the guarantee of product quality in the plastics processing industry. An important production link, but there are still problems in the existing plastic particle crushing. For example, the patent application number 201320704311.7 includes a cutting machine base, a slitting mechanism and a shaft cutting mechanism. The slitting mechanism is provided with a rubber The slitting mechanism includes a slitting knife, an adjusting plate, an adjusting rod and an elastic part. The adjusting plate is set on the top of the cutting machine base and i...

[0002] In the process of extrusion production technology in plastic processing, the extruder produces the required plastic particles through processes such as stranding and pelletizing. The pelletizing quality of the pelletizer will affect the quality of the product. This is the guarantee of product quality in the plastics processing industry. An important production link, but there are still problems in the existing plastic particle crushing. For example, the patent application number 201320704311.7 includes a cutting machine base, a slitting mechanism and a shaft cutting mechanism. The slitting mechanism is provided with a rubber The slitting mechanism includes a slitting knife, an adjusting plate, an adjusting rod and an elastic part. The adjusting plate is set on the top of the cutting machine base and is separately set from the cutting machine base. There is a rotating handle at the top, and the other end of the adjusting rod is fixed to the cutter shaft of the slitting knife. There is a connecting pin on the adjusting rod between the cutter shaft and the cutting machine base. Although the cutting knife wears little, the cutting machine cannot be lowered. The falling speed of the plastic particles inside, when the falling speed of the plastic particles is too fast, the cutting effect of the cutter on the plastic particles will be poor, thus affecting the quality of the product
