Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder production, in particular to a cooling device for plastic powder production. Background Art

[0002] Plastic powder is a main material for plastic spraying process. Its components are a mixture of resin, pigment, additives and filler. In the production process of plastic powder, it needs to go through mixing, flaking, crushing and other process flows to produce the finished plastic powder.

[0003] After the production of plastic powder is completed, the temperature of the plastic powder is high and it needs to be cooled down quickly. Currently, most of them adopt natural cooling, which leads to too long cooling time and low production efficiency of the whole product. According to the search, Chinese patent document, authorization announcement number CN213055544U, discloses a plastic powder cooling device. The device can quickly reduce the temperature of plastic powder by setting a cooling box and a pipe, effectively improve the cooling efficiency and reduce the production cycle of the product. However, when the plastic powder in the device is cooled, it is accumulated inside the cooling box. This will easily cause the plastic powder in contact with the cooling box to cool quickly, while the plastic powder in the middle will cool slowly, resulting in uneven cooling and reducing the cooling efficiency of the device body. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
