Description

Technical Field

[0001] This utility model relates to the field of cooling technology in modified plastics production, and in particular to a cooling device for modified plastics production. Background Technology

[0002] In the production process of modified plastics, after precise proportioning and pretreatment, the raw materials are fed into a thermoplasticizer for high-temperature plasticization and extrusion. To ensure the dimensional accuracy and structural integrity of the modified plastics in subsequent processing and to prevent breakage or deformation due to excessive temperature, they must be cooled quickly and effectively immediately.

[0003] Traditional cooling methods generally use water cooling. As the cooling process continues, the water temperature in the tank gradually rises, causing the cooling efficiency to gradually decrease. It is difficult to guarantee the cooling effect of the plastic. Furthermore, the continuous rise in water temperature in the tank will further affect the uniformity of cooling of modified plastics, increasing the risk of quality problems during plastic production, such as structural changes or performance degradation caused by local overheating, which in turn affects the stability of the entire production line and the quality of the final product.

[0023] Working principle: First, the plastic to be cooled is placed above the conveyor belt 204. The first motor 203 is started to rotate the rotating rod 202. The rotating rod 202 drives the conveyor belt 204 to transfer the plastic into the box 2. The second water pump 504 is started to transfer the cold water in the water tank 503 to the first pipe 302. The cold water is conducted through the first pipe 302 to the branch pipe 301. It is sprayed for cooling through the nozzle 3 connected to one end of the branch pipe 301. At the same time, the second motor 402 is started to rotate the lead screw 401. The lead screw 401 rotates the moving ring 403 and the crossbar 404 to move up and down. The movement of the crossbar 404 drives the mixing rotating rod 406 to screen the plastic up and down and cool it evenly. Then, the first water pump 502 is started to discharge the cold water through the second pipe 501 to the water tank 503. The cold water is then transferred back to the first pipe 302 by the second water pump 504 for recycling.
