[0005] However, this patent still has the following problems: the device directly cools the cutter and plastic through the water flow in the water tank. Although this can cool the plastic and the cutter, the plastic particles discharged from the water tank will still contain a large amount of water and need to be drained again, which increases the operation steps and affects production efficiency.

[0020] The cutting mechanism 3 includes a protective frame 301, which is fixed to the front side of the granulator body 1. The protective frame 301 is fixed with a driving motor 302, and the output shaft of the driving motor 302 is fixed with a cutter 303;

[0021] The protection frame 301 is used to support the driving motor 302 and protect the cutter 303. When the driving motor 302 is started, it can drive the cutter 303 to rotate, so that the cutter 303 can cut the extruded plastic strips to form plastic particles.

[0022] The cooling mechanism 2 mainly includes a bracket 201 and a material receiving box 209; the bracket 201 is installed on the periphery of the cutting mechanism 3, a cooling box 202 is fixed on the top of the bracket 201, a semiconductor refrigerator 203 is fixed on the top of the cooling box 202, a water pump 204 is connected to the surface of the cooling box 202, the discharge end of the water pump 204 is connected to a serpentine tube 205, the serpentine tube 205 is fixedly connected to the surface of the bracket 201, a first fan 206 is also fixed on the surface of the serpentine tube 205, and the serpentine tube 205 is connected to a return pipe 207, and the other end of the return pipe 207 is connected to the cooling box 202. The top of the cooling box 202 is connected; the material receiving box 209 is located below the cutting mechanism 3, and a second fan 210 is fixed on the surface of the material receiving box 209, and the second fan 210 is connected to the first diversion pipe 211 and the first diversion pipe 211 extends to the upper edges of both sides of the material receiving box 209; a blanking plate 212 is fixed to the bottom of the inner wall of the material receiving box 209, and a plurality of heat absorption tubes 213 are passed through the inner wall of the blanking plate 212, and both sides of the surface of the heat absorption tube 213 are connected to the second diversion pipe 214, and the second diversion pipe 214 passes through the material receiving box 209, and a dispersion structure is installed at the bottom of the material receiving box 209.

[0023] During the cutting process of the cutter 303, the cold water in the cooling box 202 can be transported to the inside of the serpentine tube 205 through the water pump 204, and then flow back to the cooling box 202 through the return pipe 207. In this process, the cold water itself will be transferred to the serpentine tube 205, and the first fan 206 can blow the cold water on the surface of the serpentine tube 205 to the cutter 303 when it is working, so that the cutter 303 can be cooled and prevented from overheating and adhering to the plastic.

[0030] Furthermore, a heat conducting fin 219 is fixed on the surface of the semiconductor cooler 203, and a third fan 220 is fixed on the surface of the heat conducting fin 219;

[0031] When the semiconductor cooler 203 is working, its top surface will generate heat. The heat-conducting fins 219 can absorb the heat on the surface of the semiconductor cooler 203.
