Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for PVC pipe production, in particular to a PVC pipe pulling machine. Background Art

[0002] In the process of pipe manufacturing, when the plastic pipe after sizing and cooling enters the next stage of processing, the plastic pipe is relatively long, and the front end has been cooled, but the rear end has not been sized. During the manual operation and transmission process in production, once the front tension is too large, the pipe is easily deformed, affecting the product quality. The existing patent is a traction machine for PVC water pipe production, with patent number CN208070982U. When in use, the pipe can be horizontally transmitted through the upper and lower transmission devices, and the sponge layer can shrink when in contact with the pipe to prevent the pipe from being deformed under pressure due to its soft texture.

[0003] After searching, it was found that the announcement number was CN219256421U, and the name was a PVC pipe traction machine. The application proposed a patent number CN208070982U. In the process of traction and transmission of the PVC pipe, there was no mechanism to limit the PVC pipe, which caused the PVC pipe to easily break away from the traction mechanism during the traction and transmission process, resulting in the problem that the PVC pipe could not be normally pulled and transmitted. By manually driving the screw to rotate, the guide block slides in the guide groove set at the column, so that the position of the movable plate can be adjusted to make the position of the limiting hole opened on the movable plate correspond to the traction mechanism, and then the PVC pipes that need to be pulled and transmitted pass through the limiting holes opened on the movable plates set by the two limiting mechanisms respectively, and then Then the chassis controls the traction mechanism to traction and transmission of the PVC pipe, thereby ensuring the normal traction and transmission of the PVC pipe. At the same time, by arranging multiple balls on the inner side of the limiting hole, after the PVC pipe passes through the limiting hole, the balls are used to abut against the outer wall of the PVC pipe. When the PVC pipe is in the process of traction and transmission, it will drive the balls to roll, thereby effectively reducing the friction between the PVC pipe and the limiting hole, thereby reducing the wear of the PVC pipe in the process of traction and transmission. However, when the application is actually used, the spacing between the balls cannot be adjusted, which means that it cannot adapt to the use of PVC pipes of different diameters, and it has high limitations. At the same time, when the height is adjusted, multiple sets of screws need to be rotated at the same time, which is inconvenient to adjust and use, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
