[0008] The circulating heat dissipation mechanism is located on the outside of the water tank body. It is used to re-transport the used cooling water into the water tank body for reuse and to cool the cooling water during the return flow process.

[0009] The sizing sleeve has a sliding ring rotatably mounted on its side, and a straight slide rail is slidably mounted on the side of the sliding ring. The side of the straight slide rail away from the sliding ring is connected to the inner side of the water tank body. The sliding ring moves under the drive of the adjusting mechanism, thereby adjusting the position of the sizing sleeve to connect with both ends of the pipe. The inner side of the sizing sleeve is used to install a clamping device to fix the pipe inside the sizing sleeve. The sizing sleeve rotates under the drive of the adjusting mechanism, so that the pipe rotates at a uniform speed during cooling.

[0010] Preferably, a sealing door is rotatably provided at the end of the water tank body, and a pull ring is provided on the side of the sealing door. There are two sealing doors symmetrically arranged about the water tank body.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] 1. By adjusting the mechanism, rotating the threaded rod drives the sliding ring to the end of the pipe for installation, thus adapting to pipes of different sizes. During spray cooling, the pipe rotates within the water tank, allowing the sizing sleeve to better fit the two ends of the pipe. This ensures uniform sizing pressure throughout the pipe's length, preventing dimensional deviations and surface unevenness caused by mismatch between the sizing sleeve and the pipe. Simultaneously, the cyclic rotation of the pipe ensures that all parts of the pipe are fully in contact with the cooling water, achieving uniform cooling. It also reduces stress concentration within the pipe, preventing cracking and deformation during subsequent use.

[0023] 2. Through the setting of the circulating heat dissipation mechanism, the second motor drives the spiral conveyor plate to rotate, thereby transporting the water at the bottom of the water tank to the top for reuse. During the transportation process, the cooling water is cooled down, which can significantly reduce the amount of fresh water used, thereby reducing water consumption and helping to achieve sustainable water use. At the same time, it can ensure that the cooling water maintains a stable temperature in the vacuum shaping water tank, thereby providing a stable cooling effect. This helps the plastic pipe maintain a uniform cooling rate during the shaping process and improves product quality. Attached Figure Description

[0031] The adjustment mechanism is located inside the water tank body 1. It is used to adjust the position according to the length of the produced plastic pipe to clamp both ends of the pipe and drive the pipe to rotate in a cycle during the cooling process.

[0032] The circulating heat dissipation mechanism is located on the outside of the water tank body 1, and is used to re-transport the used cooling water into the water tank body 1 for reuse, and to cool the cooling water during the return flow process.

[0033] A sliding ring 502 is rotatably provided on the side of the sizing sleeve 508, and a straight slide rail 501 is slidably provided on the side of the sliding ring 502. The side of the straight slide rail 501 away from the sliding ring 502 is connected to the inner side of the water tank body 1.

The inner side of the sizing sleeve 508 is used to install a clamping device, thereby fixing the pipe inside the sizing sleeve 508. The sizing sleeve 508 rotates under the drive of the adjusting mechanism, so that the pipe rotates at a uniform speed during cooling.

[0034] A sealing door 3 is rotatably provided at the end of the water tank body 1, and a pull ring 4 is provided on the side of the sealing door 3. There are two sealing doors 3 symmetrically arranged about the water tank body 1.

The rotating assembly includes a connecting frame 503, a motor 504, a rotating shaft 505, and a spur gear 506. The connecting frame 503 is located on the side of the sliding ring 502 away from the sizing sleeve 508. The motor 504 is located inside the connecting frame 503.

When the motor 504 is started, the motor 504 drives the rotating shaft 505 to rotate. The rotating shaft 505 drives the spur gear 506 to rotate. The spur gear 506 drives the sizing sleeve 508 to rotate through the gear ring 507, thereby driving the pipe clamped inside the sizing sleeve 508 to rotate.

[0037] Example 2

[0038] like Figures 1-4 As shown, this utility model proposes a vacuum-formed water tank for plastic pipes. Compared with Embodiment 1, this embodiment details the structure of the circulating heat dissipation mechanism.

[0039] The circulating cooling mechanism includes a first connecting pipe 601, a rotating pipe 602, a second connecting pipe 603, and a cooling pipe 611. The first connecting pipe 601 is located on the outside of the water tank body 1.

The second connecting pipe 603 is rotatably located at the top of the rotating pipe 602, and the end of the second connecting pipe 603 away from the rotating pipe 602 is connected to the outside of the water tank body 1. The cooling pipe 611 is located on the second connecting pipe 603. The top of the cooling pipe 611 has an upward-opening conical opening to increase the heat dissipation area of ​​the cooling water. A spiral conveying plate 604 is located on the inside of the rotating pipe 602, and a connecting shaft 605 is located at the axis of the spiral conveying plate 604. A second gear ring 606 is located on the outside of the rotating pipe 602, and a second spur gear 606 meshes with the side of the second gear ring 606. 07. A rotating shaft 608 is provided on the side of the second spur gear 607. A motor 609 is provided at the end of the rotating shaft 608 away from the second spur gear 607. A fixing frame 610 is provided on the outside of the motor 609. The side of the fixing frame 610 is connected to the outside of the water tank body 1. When the motor 609 is started, the motor 609 drives the second spur gear 607 to rotate through the rotating shaft 608. The second spur gear 607 drives the rotating tube 602 to rotate through the gear ring 606. The rotating tube 602 drives the internal spiral conveyor plate 604 to rotate. The end of the first connecting pipe 601 is connected to the lower chamber of the water tank body 1, and the end of the second connecting pipe is connected to the upper chamber of the water tank body 1. When the spiral conveyor plate 604 rotates, it transports the cooling water in the lower chamber upward and re-enters the upper chamber. During the transportation process, the cooling water is dissipated through the heat dissipation pipe 611.

[0040] In summary, when using this utility model, the sealing door 3 is opened by the pull ring 4, and the produced plastic pipe is then transported into the interior of the water tank body 1. Rotating the rotating rod 510 drives the threaded rod 509 to rotate. As the threaded rod 509 rotates, it moves within the water tank body 1, thereby moving the sliding ring 502 along the straight slide rail 501 to the end of the pipe. The clamping device then mounts both ends of the pipe onto the inner side of the sliding ring 502. The sealing door 3 is then closed, and simultaneously, motors 504 and 609 are started. The nozzles on the spray plate 7 spray cooling water from the upper chamber onto the pipe for cooling. During this process, motor 504 drives the rotating shaft 505 to rotate. Shaft 505 drives spur gear 506 to rotate. Spur gear 506 drives sizing sleeve 508 to rotate through gear ring, thereby causing the pipe clamped in sizing sleeve 508 to rotate. The used cooling water falls into the lower chamber. Motor 609 drives spur gear 607 to rotate through shaft 608. Spur gear 607 drives rotating tube 602 to rotate through gear ring 606. Rotating tube 602 drives the internal spiral conveyor plate 604 to rotate. When the spiral conveyor plate 604 rotates, it transports the cooling water in the lower chamber upward to re-enter the upper chamber. During the transportation process, the cooling water is dissipated through heat dissipation pipe 611, realizing the recycling of cooling water.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
