Description

PVC power tube production facility Technical Field The utility model relates to the technical field of PVC power tube production, in particular to PVC power tube production equipment. Background PVC power pipe is a plastic pipe specially used for protecting power system cable, and is called polyvinyl chloride (PVC) power cable protecting pipe, PVC belongs to semi-crystalline plastic, and when cut, the material will generate elastic deformation and plastic flow under the pressure of cutter. When the cutter penetrates through the pipe wall, the inner side material and the outer side material are different in stress release direction, so that tearing fracture can be generated on the edge to form burrs, for example, the inner side is extruded by the cutter to generate inward burrs, and the outer side is stripped to form outward burrs. The utility model patent with the bulletin number of CN217475575U discloses a C-PVC power tube polishing device, which comprises a workbench, wherein a first vertical plate is fixedly arranged at the center of one side of the top surface of the workbench, a round rod is fixedly arranged at one side of the first vertical plate, two top plates capable of vertically and axially displacing are arranged on the outer surface of the round rod, polishing wheels capable of horizontally and axially displacing are arranged on the other side of the top surface of the workbench, and the end surface of the PVC power tube is polished through the polishing wheels. The PVC power tube has different wall thicknesses according to the difference of using the scene, can produce inwards or outwards burr at the inner wall that the power tube is close to the terminal surface, outer wall owing to the characteristic of cutting after the PVC power tube is accomplished the cutting, and part just uses a big grinding wheel to polish with the terminal surface of power tube butt completely when polishing the power tube as above-mentioned patent's prior art, can't polish the burr of power tube tip inner wall and outer wall when polishing. Disclosure of utility model The utility model aims to provide PVC power tube production equipment for solving the defects in the prior art.
