Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

A limiting plate 8 is fixedly connected to the top side of the sliding rod 5. An electrode plate 9 is installed on the top side of the limiting plate 8. An L-shaped plate 10 is installed on the top side of the support frame 1. An electrode piece 11 is installed on the inner wall of the top side of the L-shaped plate 10 directly above the electrode plate 9. A water storage tank 12 is installed directly below the support frame 1. The top side of the water storage tank 12 is connected to a circulation pipe 13. One end of the circulation pipe 13 is connected to the water storage tank 2. A circulation pump 14 is installed on the outer wall of the circulation pipe 13. One side of the water storage tank 2 is connected to a delivery pipe 15. One end of the delivery pipe 15 is connected to the water storage tank 12. A water pump 16 is installed on the outer wall of the water storage tank 12. A control panel 39 is installed on one side of the support frame 1. During operation, in practical applications, the water temperature change in the water storage tank 2 cannot be understood in real time, and the water temperature may be too high, so that suitable cooling conditions cannot be stably provided for the powder coating after tablet pressing, thus reducing the cooling effect on it. When the water temperature in the water storage tank 2 rises, the water will expand and enter the connection cavity 3. As the water pressure increases, the piston plate 6 is pushed to move upward along the connection cylinder 4, and the compression spring 7 is compressed. The limiting plate 8 drives the electrode plate 9 to approach the electrode piece 11. When the electrode plate 9 contacts the electrode piece 11, an electrical signal is generated and transmitted to the control panel 39. The control panel 39 controls the operation of the circulation pump 14 and the water pump 16. The hot water is pumped from the water storage tank 2 into the water storage tank 12 through the circulation pipe 13 by the circulation pump 14. At the same time, the cold water in the water storage tank 12 is sent back to the water storage tank 2 through the delivery pipe 15 by the water pump 16.

Three buffer springs 24 are equidistantly and fixedly connected between the scraper 23 and the installation frame 21. The buffer springs 24 are respectively sleeved on the outer walls of the T-shaped rods 22. During operation, in order to ensure that the tablet pressing operation can be carried out stably and continuously, the raw materials after tablet pressing will fall onto the conveyor belt 19. The conveyor motor 20 is started to drive the rotating shaft 17 to rotate, so that the rotating roller 18 rotates accordingly, thereby driving the conveyor belt 19 to move. The conveyor belt 19 conveys the tablet pressings. Among them, the water storage tank 2 is made of stainless steel. During the conveying process, the bottom side of the powder tablet pressings is cooled by water through the conduction of the conveyor belt 19. When the conveyor belt 19 is running, the scraper 23 always fits with the bottom outer wall of the conveyor belt 19 under the combined action of the buffer spring 24 and the damper. The scraper 23 scrapes off the powder or impurities remaining on the surface of the conveyor belt 19, keeping the conveyor belt 19 clean and ensuring the cooling effect and the stability of the conveying.

During operation, the tablet pressing device extrudes the molten material to form tablets. After cooling, it is pulverized, ground and sieved to obtain the finished powder coating. In order to improve the cooling effect, the driving motor 31 is started to drive one of the rotating shafts 27 to rotate. The driving wheel 28 on this rotating shaft 27 drives the driven wheel 29 to rotate through the belt 30, so that the other rotating shaft 27 also rotates synchronously.

The driving gear 35 and the driven gear 36 mesh with each other, causing the two pressing rollers 37 to rotate towards each other to perform a tablet pressing operation on the powder coating.

[0030] The tableted raw material will fall onto the conveyor belt 19. The conveyor motor 20 is started to drive the rotating shaft 17 to rotate, causing the rotating roller 18 to rotate accordingly, thereby driving the conveyor belt 19 to move. The conveyor belt 19 conveys the tablets. Among them, the water storage tank 2 is made of stainless steel. During the conveying process, the bottom side of the powder tablets is cooled by water through the conduction of the conveyor belt 19. At the same time, the scraper 23 always fits against the outer wall of the bottom side of the conveyor belt 19 under the combined action of the buffer spring 24 and the damper.

The rotating shaft 27 drives the fan blades 32 to rotate, generating a downward airflow to perform air cooling on the surface of the powder tablets passing through the cooling chamber 25 and accelerating the cooling process.

[0032] When the water temperature in the water storage tank 2 rises, the water will expand and enter the connection cavity 3. As the water pressure increases, the piston plate 6 is pushed to move upward along the connection cylinder 4, and the compression spring 7 is compressed. The limit plate 8 drives the electrode plate 9 to approach the electrode piece 11. When the electrode plate 9 contacts the electrode piece 11, an electrical signal is generated and transmitted to the control panel 39. The control panel 39 controls the operation of the circulation pump 14 and the water extraction pump 16. The hot water is pumped from the water storage tank 2 into the water storage tank 12 through the circulation pipe 13 by the circulation pump 14. At the same time, the cold water in the water storage tank 12 is sent back to the water storage tank 2 through the delivery pipe 15 by the water extraction pump 16. Ice cubes or cold water can be added to the water storage tank 12 to reduce the temperature of the water inside it, so as to adjust the water temperature and avoid the influence of too high water temperature on the cooling effect.
