[0029] Example: An extrusion cooling and shaping device for producing plastic pipes, such as... Figs. 1-3 As shown, a cooling box 1 includes a water outlet 2 at the bottom and a valve 13 at the water outlet 2. Two opposing vertical rotating disks 3 are rotatably arranged inside the cooling box 1. The rotating disks 3 can be divided into an upper cooling part 4 and a lower cooling part 5. The upper cooling part 4 and the lower cooling part 5 are symmetrically arranged and each has three placement holes 6. The placement holes 6 on the front rotating disk 3 and the placement holes 6 on the rear rotating disk are located on the same straight line in a one-to-one correspondence. A rotating shaft 7 is rotatably arranged on the top of the cooling box 1. The rotating shaft 7 passes through the center of the two rotating disks 3 in sequence and is slidably connected to the rotating disks 3. The rotating shaft 7 is threaded. Limiting rings 8 are provided on both sides of the rotating disks 3. The limiting rings 8 are threadedly connected to the rotating shaft 7 to limit the rotation of the rotating disks 3.

[0030] Specifically, it also includes a drive motor 9, with a gear 10 fixed at the output end of the drive motor 9 and a gear 2 11 fixed at one end of the rotating shaft 7, the gear 10 meshing with the gear 2 11.

[0031] Its working principle is as follows: First, the limiting ring 8 is turned to release the limiting of the rotating disk 3. The distance between the two rotating disks 3 is adjusted by sliding according to the length of the plastic pipe. After adjustment, the limiting ring 8 is turned closer to the rotating disk 3 until the rotating disk 3 is tightened and fixed on the rotating shaft 7. Then, a sufficient amount of cooling water is introduced into the cooling box 1, and multiple plastic pipes to be cooled are squeezed into the placement hole 6 of the upper cooling part 4, so that they are supported on the front and rear rotating disks 3. The drive motor 9 is started to drive the gear 10 to rotate, the gear 10 drives the gear 2 11 to rotate, thereby driving the rotating shaft 7 to rotate. The rotating shaft 7 drives the rotating disk 3 to rotate 180 degrees automatically each time. At this time, the upper cooling section 4 is completely immersed in the cooling water, so that the cooling water evenly wraps around the pipe and achieves all-round cooling. During the cooling process, plastic pipes can be squeezed into the placement hole 6 of the lower cooling section 5 located above, completing the loading of the lower cooling section 5. After cooling is completed, the rotating shaft 7 is rotated again to drive the rotating disk 3 to rotate 180 degrees. At this time, the pipes of the lower cooling section 5 enter the cooling water, and the upper cooling section 4 is exposed above the water surface. During the cooling process of the lower cooling section 5, the plastic pipes of the upper cooling section 4 are naturally dried, unloaded and loaded. The cycle is repeated to achieve continuous and efficient cooling. Multiple plastic pipes can be cooled at one time, with uniform cooling, good cooling effect and high efficiency.

[0032] Specifically, a V-shaped retractable transport channel 12 is fixedly connected between the placement hole 6 on one turntable 3 and the placement hole 6 on the next turntable. When the transport channel 12 moves to the top, its opening faces upward. Multiple transport channels 12 are arranged in parallel, which makes it convenient to slide the plastic tube through one placement hole 6 into another placement hole 6 to be supported on the turntable 3, thereby improving the feeding efficiency.

[0033] Specifically, the transport channel 12 is made of silicone or thermoplastic polyurethane material to ensure that the transport channel 12 can deform appropriately according to the distance between the rotating disks 3 and can also protect the plastic pipe.

[0034] Specifically, the top of the cooling box 1 is provided with circular sliding holes 14 on both sides, and the rotating shaft 7 is rotatably connected in the sliding holes 14 to realize the rotatable connection between the rotating shaft 7 and the cooling box 1.

[0035] Specifically, a sealing ring is provided on the outside of the sliding hole 14, and the rotating shaft 7 is rotatably and sealingly connected to the sealing ring, thereby rotatably and sealingly connecting the rotating shaft 7 to the cooling box 1 to prevent cooling water leakage.

[0036] Specifically, it also includes a bracket 15, on which the cooling box 1 is fixedly connected to achieve stable support for the cooling box 1.
