[0002] As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption and other advantages. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, and polypropylene PPR hot water pipes. With the continuous development of society, plastic pipes have been widely used. Plastic pipes need to go through multiple processes in the production and processing process, among which the traction process is an important part.

[0003] The existing traction device for producing PVC drain pipes places the PVC drain pipes between conveyor belts, and then brings the conveyor belts close to each other to clamp and transport the PVC drain pipes. However, since the conveyor belts are in direct and rigid contact with the surface of the PVC drain pipes, the traction and clamping force on the PVC drain pipes may be too large, causing the outer circle of the PVC drain pipes to deform. In addition, the PVC drain pipes may deviate from the center line when being clamped and transported between the conveyor belts, causing the PVC drain pipes to bend and deform, which is quite inconvenient.

[0004] Therefore, a traction device for PVC drain pipe production has been developed, which can protect the surface of the PVC drain pipe, avoid deformation of the outer circle of the PVC drain pipe caused by direct hard contact, and can center the PVC drain pipe to avoid bending and deformation of the PVC drain pipe.
