Description
Technical Field
[0001] The utility model relates to the technical field of crushing devices, in particular to a plastic particle crushing device. Background Art
[0002] Plastic granules are a kind of granular plastic material, mainly produced from raw materials or processed from waste plastics. They have the characteristics of chemical stability, cold resistance, heat resistance, moisture resistance, corrosion resistance, etc., and are easy to process and shape. They are widely used in the production of various plastic products, such as packaging bags, barrels, pipes, etc., and are also used in the manufacture of clothing, tools, doors and windows, etc.
[0003] In the process of crushing plastic particles, a lot of dust is often generated. During long-term processing and use, it is easy to affect the workshop environment. In addition, the plastic particles need to be cooled when they are crushed. Cooling helps to reduce the temperature of the plastic particles and prevent them from sticking or deforming due to high temperature during the cutting process. Cooling can make them hardened and easy to cut. However, the existing plastic particle crushing device does not have the function of cooling the plastic particles when in use, and does not propose a solution to the dust generated during the production of plastic particles. In order to solve the above problems, when processing plastic particles, it is convenient to cool them in advance to facilitate subsequent processing, and the dust generated when the plastic particles are crushed can be processed to facilitate use during processing. For this reason, we propose a plastic particle crushing device. Utility Model Content
