Plastic particle cooling device

Abstract

The invention discloses a plastic particle cooling device which comprises a containing barrel, a rotation disc, a cooling column, a base plate, a rotating motor, a lifting hydraulic cylinder, a water inlet hose and a water return hose; a round through hole is formed in the bottom of the containing barrel; the rotation disc is rotationally arranged in the round through hole through a bearing; a plurality of vertically-extending sliding through holes are formed in the rotation disc; the upper end of the cooling column penetrates the sliding through holes and enters the containing barrel; the lower end of the cooling column is connected with the base plate; a cooling water containing cavity is formed in the cooling column; the cooling water containing cavity is opened at the end face of the lower end of the cooling column; a water colleting cavity is formed in the base plate; the water collecting cavity is communicated with the cooling water containing cavity; the water inlet hose and the water return hose are communicated with the water colleting cavity; a rotating shaft of the rotating motor is connected with the bottom face of the base plate; and a shell of the rotating motor is connected with a piston rod of the lifting hydraulic cylinder. The plastic particle cooling device is high in cooling efficiency and is suitable for plastic particles in different number.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a cooling device for plastic particles. Background technique [0002] In the process of processing plastic granules, it is necessary to melt the plastic first, and then mold the plastic through a mold to obtain plastic granules. Plastic pellets need to be cooled to a lower temperature before being processed in the next step. If the plastic is placed to allow it to dissipate heat naturally through the air, it will take a lot of time, resulting in reduced production efficiency. Although the cooling time can be reduced to a certain extent through vibration or stirring to assist heat dissipation, it still cannot meet the needs of rapidly cooling plastic particles to greatly improve production efficiency. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems of the prior art, and provide a cooling device for plastic gra...

If the plastic is left to cool naturally through the air, it will take a lot of time, resulting in reduced production efficiency

Although the cooling time can be reduced to a certain extent through vibration or stirring to assist heat dissipation, it still cannot meet the needs of rapidly cooling plastic particles to greatly improve production efficiency.
