[0012] In a preferred example, the utility model can be further configured as follows: the fan blades are arranged inside the air inlet channel and outside the filter plate.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] In the utility model, after the raw materials are put into the main material cavity, the motor drives the rotating shaft, the cylinder body and the box body to rotate. Each time the box body rotates one circle, a part of the raw materials will be filled, and then thrown into the inside of the sprinkling trough, and then diverted by two material distribution channels, which increases the movement diameter of the raw materials and makes it easier for the raw materials to dissipate heat. Then, under the cooperation of the pulley and the belt, the bevel gear shaft one rotates simultaneously with the rotating shaft, and then the bevel gear shaft two meshing with the bevel gear shaft one rotates with the fan blades.

[0024] A cooling mixer for producing polyvinyl chloride pellets provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] Combination Figure 1-4 As shown, the utility model provides a cooling mixer for the production of polyvinyl chloride pellets, comprising a mixing device 100 and a cooling device 200, wherein the mixing device 100 comprises a drying box 110, a main material cavity 120 and a material sprinkling trough 130 opened on the top of the drying box 110, two material distribution channels 140 opened inside the drying box 110, a rotating shaft 150 movably installed inside the main material cavity 120, a motor 160 connected between the drying box 110 and the rotating shaft 150, a cylinder 170 sleeved on the outside of the rotating shaft 150, a plurality of box bodies 180 enclosed on the outside of the cylinder body 170, and a filter plate 190 installed inside the drying box 110, wherein the box body 180 is in contact with the inner wall of the main material cavity 120;

[0027] The cooling device 200 includes an L-shaped plate 210 installed on one side of the drying box 110, a bevel gear shaft 220 movably passing through the rear side of the L-shaped plate 210, two pulleys 230 respectively sleeved on the rotating shaft 150 and the rear end of the bevel gear shaft 220, a belt 240 connected between the two pulleys 230, a bevel gear shaft 250 meshed on one side of the bevel gear shaft 220 and movably connected to the L-shaped plate 210, and a fan blade 260 sleeved on the inner end of the bevel gear shaft 250.

[0028] Furthermore, the material sprinkling trough 130 is arranged on one side of the main material chamber 120 and is connected to the interior of the main material chamber 120. The two ends of the material distribution channel 140 are respectively connected to the interior of the main material chamber 120 and the material sprinkling trough 130. This structural design ensures that the raw materials can circulate, increases the activity space of the raw materials, and increases the cooling efficiency.

[0029] Furthermore, an air inlet channel is opened on one side of the drying box 110, and the air inlet channel is connected to the inside of the two material distribution channels 140. The filter plate 190 is located inside the air inlet channel. This structural design ensures that the wind generated by the fan blades 260 can be smoothly blown into the material distribution channel 140, and the filter plate 190 can prevent the raw materials from spilling into the air inlet channel.

[0030] Furthermore, the bevel gear shaft 1 220 and the bevel gear shaft 2 250 have the same structure, and the length of the bevel gear shaft 1 220 is greater than the length of the bevel gear shaft 250. This structural design reduces the difficulty of manufacturing the device.

[0031] Embodiment 2:

[0032] Combination Figure 1-2 As shown, based on the first embodiment, the bottom of the inner cavity of the material sprinkling trough 130 is set as an inclined surface. With this structural design, the raw materials sprinkled into the material sprinkling trough 130 can slide into the material distribution channel 140 by themselves, thereby avoiding the accumulation of raw materials and improving the heat dissipation effect.

[0033] Embodiment three:

[0034] Combination Figure 4 As shown, in the above embodiment, the fan blades 260 are arranged inside the air inlet channel and located outside the filter plate 190. With this layout design, the fan blades 260 can rotate flexibly.

[0035] The working principle and use process of the utility model are as follows: when the device is put into actual use, the raw materials are mainly placed inside the main material chamber 120, and then the motor 160 is started, and the rotating shaft 150 rotates with the cylinder 170 and the box body 180. Every time the box body 180 rotates one circle, it will be filled with a portion of the raw materials, and then thrown into the inside of the sprinkling trough 130, and then diverted by the two material distribution channels 140, so that the raw materials can circulate, which increases the movement diameter of the raw materials and makes it easier for the raw materials to dissipate heat. Then, under the cooperation of the pulley 230 and the belt 240, the bevel gear shaft 1 220 rotates simultaneously with the rotating shaft 150, and then the bevel gear shaft 250 meshing with the bevel gear shaft 1 220 rotates with the fan blades 260, and the wind generated by the fan blades 260 blows towards the raw materials entering the material distribution channel 140 at all times, effectively improving the heat dissipation efficiency.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
