Description

Technical Field

[0001] The present application relates to the field of particle manufacturing technology, and in particular to a plastic particle manufacturing device. Background Art

[0002] With the increasing awareness of environmental protection and the increasing scarcity of resources, plastic recycling has become one of the focuses of global attention. As the basic raw materials of various plastic products, the quality of plastic particles in the production process directly affects the performance of the final product.

[0003] Currently, in order to improve the recycling rate of waste plastics, existing technologies provide several solutions. The first is the physical crushing method, which uses mechanical force to crush waste plastics into fine particles. This method is simple and easy to use, but the size of the crushed particles is uneven and easily mixed with impurities, which reduces the quality of the finished product. The second is the chemical dissolution method, which uses a specific solvent to dissolve the waste plastics and then solidify them into a shape. Although this method can produce relatively pure particles, it is expensive and there is a risk of environmental pollution. The third is the pyrolysis and gasification method, which uses high temperature to decompose waste plastics into low-molecular compounds, and then obtains plastic particles through processes such as condensation. This method can effectively remove harmful substances in plastics, but the equipment is complex and difficult to maintain, making it unsuitable for small businesses.

[0004] These traditional treatment methods generally have problems of high energy consumption and low efficiency. Especially when dealing with large amounts of waste plastics, it is difficult to achieve a balance between economy and environmental friendliness. In addition, due to the lack of effective cleaning measures, the recycled plastic particles are often of unstable quality, affecting subsequent processing and applications. Utility Model Content

[0037] See Figure 1 The inner wall of the transfer pipe 10 is provided with a solenoid valve, the screw 15 is made of stainless steel, and the cutting knife 24 is made of high-speed steel. The bottom of the cleaning chamber 2 is fixedly connected to the water outlet pipe 8, and the outer edge of the water outlet pipe 8 is installed with a control valve, so that the solenoid valve can be opened to put the plastic cleaned in the inner cavity of the cleaning chamber 2 into the inner cavity of the melt extrusion chamber 11, and water and plastic will not enter the interior at will during cleaning.

[0038] See Figure 2 and Figure 3 A protective cover is fixedly installed on the outside of the melt extrusion chamber 11, and the transmission belt 14 and the transmission wheel 13 are both arranged in the inner cavity of the protective cover, so that the protective cover can be used to protect the transmission wheel 13 and the transmission belt 14, ensuring that they will not be directly exposed to the outside, and thus will not come into contact with the body of the staff during the operation, thereby improving safety.

[0039] Working principle: First, waste plastic is fed into the inner cavity of the cleaning chamber 2 through the feeding chamber 3, and then the motor 15 is driven to drive the spiral blade 4 to rotate. A gear 6 can be used to cooperate with another gear 6 to transmit the rotational force to the other spiral blade 4, so that the two spiral blades 4 can rotate synchronously to stir the material fed into the inner cavity of the cleaning chamber 2, which is used to remove dust and other pollutants on the surface of the plastic, ensure that the plastic entering the melt extrusion chamber 11 is clean and pollution-free, and ensure its thorough cleaning.

After the plastic strip is extruded from the die head 16, it is immediately immersed in the cooling water tank 17. After it is completely cooled, the electric telescopic rod 23 is started to drive the cutting knife 24 to move downward to cut it into small segments of a specified length. The screw 21 is driven to rotate by the driving motor 20, and then the slider 22 can be used to drive the electric telescopic rod 23 and the cutting knife 24 to move their positions, so as to facilitate cutting the plastic strips into different lengths.
