Description

Technical Field

[0001] This utility model relates to the field of cooling technology, and more specifically, to a cooling device for a thermosetting powder coating tablet press. Background Technology

[0002] In the existing cooling device technology for thermosetting powder coating tablet presses, the cooling water circulation system, as a key device for maintaining the normal operating temperature of the tablet press and ensuring product quality, has certain defects in the connection method between its inlet and outlet ends and the external water pipes.

[0003] Traditional cooling water pipe connections typically employ threaded connections, compression fittings, or welding for fixation. In practical use, when maintenance, cleaning, or component replacement is required, operators must use specialized tools to perform complex disassembly of the inlet and outlet connections. This is not only cumbersome and time-consuming but also demands specialized skills and experience, increasing the difficulty and cost of equipment maintenance. Secondly, due to limitations in the connection structure design and the aging and wear of sealing materials, traditional connection methods are prone to deterioration in sealing performance over long-term use, leading to leakage or seepage of cooling water at the connection points. This not only wastes cooling water and pollutes the environment but also affects the stability of the cooling system's circulation pressure and flow rate, consequently impacting the uniformity and continuity of the cooling effect. These disadvantages affect the normal operation and production efficiency of thermosetting powder coating tablet presses, and also increase equipment maintenance costs and the risk of failure.

[0009] Preferably, a first push rod is connected to the other side of the first sealing disc, and a first retaining ball is provided at the middle position of the surface of the first push rod. A second push rod is connected to the other side of the second sealing disc, and a second retaining ball is provided at the middle position of the second push rod.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a cooling device for a thermosetting powder coating tablet press, which has the following advantages: This cooling device for a thermosetting powder coating tablet press solves the problems of complex connection between the water inlet and outlet, difficult disassembly and assembly, and poor sealing in traditional cooling devices, and realizes convenient operation and reliable sealing of cooling water pipeline connection.

[0013] This device allows operators to reliably connect the first and second pipelines with a simple insertion action, eliminating the need for any special tools or complex operations.

The dual-sealing system, through the tight contact between the sealing disc and the partition plate, combined with the differential thrust mechanism of the compression spring and the ring spring, ensures complete sealing of the pipeline in the disconnected state and automatic opening in the connected state. The compression spring provides continuous sealing pressure to the sealing disc, and the ring spring switches the thrust direction by changing the position of the retaining ball, forming a self-locking sealing control system that effectively prevents cooling water leakage. To prevent the intrusion of external contaminants, the linkage design of the push rod and the locking ball enables synchronous control of the sealing state of the two pipelines. When the pipelines are connected, the push rods abut against each other to push the sealing disc to move, and the locking ball passes through the ring spring to form a reverse locking force, ensuring the stable maintenance of the connection state. When it is necessary to disconnect the connection, simply push the push rod at the same time to easily release the connection and restore the sealing state. The entire cooling device achieves efficient circulation of cooling water through the through connection of the cold water tank in the pressure plate and the water pipe, solving the problems of inconvenient installation and disassembly and poor sealing of traditional cooling devices, and improving the maintenance efficiency and reliability of the equipment.

[0019] Please see Figures 1 to 6A cooling device for a thermosetting powder coating tablet press includes a pressure plate 11 with a cold water tank 12 inside; it also includes a connecting mechanism, which includes a first pipe 21, a first water pipe 22 on the side wall of the first pipe 21, the first water pipe 22 being connected to the cold water tank 12 inside the pressure plate 11, a first threaded pipe 23 being threaded into the first pipe 21, multiple sets of elastic hooks 24 on the other end of the surface of the first pipe 21, and a second pipe 25 detachably connected to the side wall of the first pipe 21, the side wall of the second pipe 25 having a second water pipe 24. 6. The surface of the second pipe 25 is provided with a groove 27 that matches the elastic hook 24. The inner wall of the other end of the second pipe 25 is threaded with a second threaded pipe 28. The first pipe 21 is provided with a first partition 29. The first threaded pipe 23 is slidably connected with a first push rod 210. The other end of the first push rod 210 is provided with a first sealing disc 211. The first sealing disc 211 is sealed to the first partition 29. The second pipe 25 is provided with a second partition 212. The second threaded pipe 28 is slidably connected with a second push rod 213. The other end of the second push rod 213 is provided with a... A second sealing disc 214 is provided, which is sealed to the second partition 212. A first compression spring 215 is provided on the side wall of the first threaded tube 23, and the other end of the first compression spring 215 is fixedly connected to the side wall of the first sealing disc 211. A second compression spring 216 is provided on the side wall of the second threaded tube 28, and the other end of the second compression spring 216 is fixedly connected to the side wall of the second sealing disc 214. A first push rod 217 is connected to the other side of the first sealing disc 211, and a first retaining ball 218 is provided at the middle position of the surface of the first push rod 217. A second sealing disc 214 is connected to the other side of the second sealing disc 214. The second push rod 219 has a second locking ball 220 at its middle position. The first pipe 21 has a first limiting ring 221, and the first push rod 210 is slidably connected to the first limiting ring 221. The second pipe 25 has a second limiting ring 222, and the second push rod 213 is slidably connected to the second limiting ring 222. The first pipe 21 has a first annular spring 223, which abuts against the first locking ball 218. The second pipe 25 has a second annular spring 224, which abuts against the second locking ball 220.

[0020] Under normal conditions, the first water pipe 22 of the first pipeline 21 is connected to the cold water tank 12 inside the pressure plate 11, and the second water pipe 26 of the second pipeline 25 is connected to the external cold water circulation mechanism. When the first pipeline 21 and the second pipeline 25 are not connected, the first pipeline 21 is in a sealed state. The first sealing disc 211 is tightly abutted against the side wall of the first partition 29 by the thrust of the first compression spring 215. At the same time, the first ring spring 223 abuts against one side of the first retaining ball 218, providing the first retaining ball 218 with a thrust in the same direction as the thrust of the first compression spring 215, further reinforcing the seal of the first sealing disc 211 and the first partition 29, thereby achieving the seal of the cold water tank 12 and preventing leakage. Similarly, the second pipeline 25 operates on the same principle to achieve the seal of the external cold water circulation mechanism. When it is necessary to connect the external cold water circulation mechanism and the cold water tank 12, the operator needs to forcefully insert the second pipe 25 into the first pipe 21. The elastic hook 24 engages in the slot 27 to connect the first pipe 21 and the second pipe 25. At this time, the first push rod 217 and the second push rod 219 abut against each other. Under the action of external force, the first push rod 217 will slide towards the first partition 29, thereby pushing the first sealing disc 211 to move and release the seal with the first partition 29. The first push rod 210 moves synchronously, and the first locking ball 218 will also move with the first push rod 217, passing through the first annular spring 223. At this time, the first annular spring 223 abuts against the other side of the first locking ball 218. The first annular spring 223 begins to provide a thrust opposite to the first compression spring 215, and the thrust of the first annular spring 223 is greater than that of the first compression spring 215. The thrust of the compression spring 215 fixes the position of the first push rod 217. Similarly, the second push rod 219 slides towards the second partition 212, thereby pushing the second sealing disc 214 to move and release the seal with the second partition 212. The second push rod 213 moves synchronously, and the second locking ball 220 also moves with the second push rod 219, passing through the second annular spring 224. At this time, the second annular spring 224 abuts against the other side of the second locking ball 220. The second annular spring 224 begins to provide a thrust opposite to that of the second compression spring 216. Similarly, the thrust of the second annular spring 224 is greater than that of the second compression spring 216, thereby fixing the position of the second push rod 219. At this time, the first pipe 21 and the second pipe 25 are in a connected state, and the external cold water circulation mechanism is in a connected state with the cold water tank 12. The other end of the cold water tank 12 inside the pressure plate 11 is equipped with the same connecting mechanism. Cooling water flows into the second pipe 25 through the second water pipe 26, then into the first pipe 21, and then into the cold water tank 12 through the first water pipe 22, thus cooling the pressure plate 11. Afterwards, it flows through the first water pipe 22 on the other side, through the first pipe 21 and the second pipe 25, and finally back to the external cold water circulation mechanism through the second water pipe 26, realizing the circulation of cooling water. When it is necessary to disconnect the connection between the first pipe 21 and the second pipe 25, the machine... The operator simultaneously pushes the first push rod 210 and the second push rod 213 inward, forcing the first sealing disc 211 and the second sealing disc 214 to once again achieve a tight seal with the first partition 29 and the second partition 212. The first retaining ball 218 and the second retaining ball 220 are pressed back to the other side of the first annular spring 223 and the second annular spring 224, thereby achieving the initial sealing state again. The pressure provided by the first compression spring 215 and the second compression spring 216 can be adjusted by rotating the first threaded tube 23 and the second threaded tube 28.

For all the fixed connections mentioned above, welding is preferred.
