Technical Field

The invention belongs to the technical field of PVC pipe processing, and particularly relates to equipment for processing PVC pipes.

Background

The cable guide pipe is a commonly used protective pipe in cable laying in various places in recent years, and frequently-used plastic pipes such as MPP, PVC and the like have poor strength, cannot bear heavy pressure, are flammable and fragile, are not heat-resistant, are not anti-aging and have short service life. In order to solve the above problems, a glass fiber tube in which glass fiber is wound around a PVC tube has been known in the prior art, and a series of apparatuses have been proposed for processing the tube. When the existing equipment is used for processing the pipe, after a metal pipe penetrates through the PVC pipe, the PVC pipe is driven to rotate through the rotation of the metal rod, so that the glass fiber is wound outside the PVC pipe. Because the metal rod is usually directly arranged on the platform, the friction resistance between the metal rod and the platform is large during rotation, the rotation speed of the metal rod is slow, and the processing efficiency is low; if a high-power motor is used for driving, the energy consumption is very large.
