Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe cooling equipment, in particular to a cooling device for cooling plastic pipes. Background Art

[0002] Plastic pipe equipment can also be called plastic pipe production line. Plastic pipe equipment is an important component of chemical building materials. It is widely accepted by users for its excellent performance, health, environmental protection, low power consumption, etc. Among them, the cooling process plays a vital role in the quality of plastic pipes.

[0003] After searching: the existing patent with authorization announcement number CN216760520U proposes a plastic pipe cooling device. During use, the fixed plate and the plastic pipe are driven to rotate and cool down by starting the motor and cooperating with the rotating shaft. After the cooling is completed, the plastic pipe is pushed to the wiper plate through the hydraulic cylinder to remove the stains on the surface of the plastic pipe, thereby solving the problem that the plastic pipe cooling device cannot evenly contact and cool down the plastic pipe.

[0004] After research, it was found that in the above-mentioned existing patent, when cooling the plastic pipe, the plastic pipe is fixed horizontally on the fixed plate. As is known to all, plastic pipes are easily deformed under high temperature conditions. The above-mentioned method will cause the plastic pipe that has not been cooled to be deformed. After cooling, the plastic pipe is likely to be bent. At the same time, even if the plastic pipe is short, there will be no deformation that affects normal use after cooling. However, when cooling, the plastic pipes that need to be cooled need to be installed on the fixed plate in turn before the subsequent cooling operations can be performed. This method takes a lot of time, which will affect the continuity of the work and further reduce the work efficiency. Therefore, the utility model proposes a cooling device for cooling plastic pipes to solve the above problems. Utility Model Content
