[0002] Plastic pellet mixer is a kind of equipment widely used in plastic processing industry. It is used to mix, melt and plasticize plastic pellets. During the mixing process, plastic pellets are subjected to high temperature and high pressure, which will generate a lot of heat. In order to ensure the quality and performance of plastic pellets, it is necessary to dissipate the heat in time to prevent the plastic pellets from overheating and causing performance degradation or defects.

[0003] Traditional plastic pellet mixers usually use water cooling or air cooling for cooling. However, these methods have certain limitations in practical applications. Although the water cooling method has a better cooling effect, the equipment structure is complex, the maintenance cost is high, and the direct contact between the cooling water and the material may cause product quality problems. Although the air cooling method has a simple structure, the cooling efficiency is low and it is difficult to meet the needs of large-scale production. For this reason, we propose a plastic pellet mixer with cooling function. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the plastic pellet mixer with cooling function, the motor switch is turned on during the cooling process to drive the cam to rotate.

[0024] Specifically, when the cooling assembly is turned on, the driving assembly is started to drive the moving plate 12 to move up and down continuously, so that the material on the surface of the moving plate 12 is lifted up, thereby improving the cooling efficiency of the material.

[0025] Wherein: a movable material blocking member is arranged in the channel connecting the internal mixer 1 and the cooling box 2 , and the material blocking member is controlled to move to a position where the channel is not blocked, so that the material in the internal mixer 1 can enter the cooling box 2 .

[0026] Wherein: the cooling assembly includes a cold air device 5 and an air outlet pipe 6, the cold air device 5 is installed on one side of the internal mixer 1, the air outlet pipe 6 is fixedly installed at the air outlet of the cold air device 5, and the other end of the air outlet pipe 6 is connected to the inner cavity of the cooling box 2. Turn on the switch of the cold air device 5, so that the air outlet pipe 6 blows air into the cooling box 2 for heat dissipation and cooling.
