The first water spray cooling device is used to spray water to the first conveyor belt, while the second water spray cooling device sprays water to cool the second conveyor belt through components such as a temperature detector, a controller, a second water pipe, a second nozzle and a valve.

The driven bevel gear 10 is meshed with the active bevel gear 11. A second synchronous wheel is fixedly sleeved on the roller 12 and the stirring roller 16. A second synchronous belt 14 is commonly sleeved on the two second synchronous wheels. A conveying pipe 15 and a drain pipe 24 are respectively fixedly connected to the inside of the body 3 by screws. A temperature sensor 20 is installed inside the body 3. A controller 4 is installed on one side of the body 3. The temperature sensor 20, the controller 4 and the motor 18 are electrically connected. Through the arrangement of structures such as the motor 18 and the stirring component 17, when using the device, the coolant is first transported to the inside of the body 3 through the conveying pipe 15, and the conveying device 1 and the motor 18 are started at the same time. The conveying device 1 drives the pellets to pass through the water spray component 23 and the exhaust fan 5 for preliminary cooling, and then transported to the inside of the body 3. The motor 18 drives the stirring component 17 to stir the coolant, thereby accelerating the cooling efficiency and solving the problem of low cooling efficiency.

[0024] like Figure 1~Figure 4 As shown, a cavity is provided inside the machine body 3, and the stirring assembly 17 is rotatably installed inside the cavity.

[0025] like Figure 1~Figure 4 As shown, a through slot is provided inside the fixing block 13, and the roller 12 is rotatably installed inside the through slot.

[0026] like Figure 1~Figure 4 As shown, circular grooves are provided inside the two first synchronous wheels, the rotating column 6 is fixedly arranged inside one of the circular grooves, and the rotating rod 8 is fixedly arranged inside the other circular groove.

[0027] like Figure 1~Figure 4 As shown, two symmetrically arranged slide grooves are provided inside the body 3, a slider 21 is slidably connected inside the slide groove, and a spring 22 is commonly connected between the bottom of the slider 21 and the inner wall of the slide groove.

[0028] In this embodiment, when using the device, first, the coolant is transported to the inside of the machine body 3 through the conveying pipe 15, and then the conveying device 1 and the motor 18 are started at the same time, and the produced pellets are transported through the conveying device 1, and the motor 18 drives the stirring roller 16 to rotate, and the stirring roller 16 drives the roller 12 to rotate under the action of the second synchronous belt 14, and the roller 12 drives the active bevel gear 10 to rotate. Since the driven bevel gear 11 and the active bevel gear 10 are meshed and connected, the driven bevel gear 11 rotates accordingly, and the driven bevel gear 11 drives the rotating rod 8 to rotate, and the rotating rod 8 and the cooling fan 9 rotate, and the rotating rod 8 drives the rotating column 6 to rotate under the action of the first synchronous belt 7, and the rotating column 6 drives the exhaust fan 5 to rotate. At this time, the two water spraying components 23 are started at the same time, and the nozzles fixed inside the water spraying components 23 and the exhaust fan 5 are used. The surface of the pellets is initially cooled, and the exhaust fan 5 can quickly discharge the heat on the surface of the pellets to reduce its surface temperature. This initial cooling method can effectively reduce the heat of the pellets and reduce the risk of deformation or cracking. Then, the pellets are automatically transported to the inside of the body 3 and finally fall to the top of the placement plate 25. At this time, the stirring roller 16 drives the stirring component 17 to rotate, thereby stirring the coolant inside the body 3. By stirring the coolant, the contact area and contact time between the coolant and the surface of the pellets can be increased to achieve a uniform cooling effect. Stirring the coolant can promote the transfer of heat from the surface of the pellets to the coolant, speed up the heat transfer rate, and enable the pellets to reach the required cooling temperature faster, which can avoid local overheating of the pellet surface, reduce the risk of deformation or cracking, and solve the problem of low cooling efficiency.

[0029] Example 2

[0030] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the body 3 is internally hinged with a door panel, the body 3 is internally slidably equipped with a placement plate 25, both sides of the placement plate 25 are fixedly connected with sliders 21 by screws, the sliders 21 are slidably connected to the inside of the body 3, and a guide plate 19 is welded to the inside of the body 3.

[0031] like Figure 1~Figure 4 As shown, two symmetrically arranged slide grooves are provided inside the body 3, a slider 21 is slidably connected inside the slide groove, and a spring 22 is commonly connected between the bottom of the slider 21 and the inner wall of the slide groove.

[0032] In this embodiment, during use, when the ball falls to the top of the placement plate 25, due to the effect of gravity, a certain impact force will be generated on the placement plate 25. At this time, the slider 21 is slidably connected to the slide groove opened inside the shell under the action of the spring 22, which can absorb and disperse the impact force of the falling ball, thereby playing a shock-absorbing role and solving the problem of poor practicality.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
