Description

Technical Field

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

[0002] Plastic products have a high temperature after molding. In order to improve production efficiency, it is usually necessary to cool the plastic products. After searching, the patent with announcement number CN221391858U discloses a continuous plastic product cooling device. Through the cooperation between the wire sleeve, the screw, the worm and the turbine, it can be driven by a motor to drive the screen frame to move up and down, and the cooling medium is circulated and cooled by the cold water circulation machine to maintain the low temperature environment at the bottom of the box. The position of the screen frame is controlled by the lifting mechanism so that the screen frame is located in the feeding area, the drainage area and the immersion area, so that it enters the bottom cooling medium for immersion cooling, with fast cooling speed and high efficiency.

[0003] Although the above solution can quickly cool down plastic products by immersion, it only has one immersion zone, and accordingly, the temperature of the cooling medium is also only one. If the temperature of the cooling medium is low, when the plastic product is immersed in cooling, the plastic product will generate large internal stress due to the sudden cooling, which may cause distortion, etc. If the temperature of the cooling structure is high, it will be difficult to reduce the temperature of the plastic product to the required level by immersion cooling, which needs to be improved.
