An anti-deviation device for pvc pipe production line

Abstract

The invention discloses an anti-deviation device for a PVC pipe production line, relates to the technical field of pipe production equipment, and specifically relates to an anti-deviation device for a PVC pipe production line, including a fixed table, a limiting rod, and a top of the fixed table. The right side is fixedly installed with two fixed frames, and the middle part of the top of the two fixed frames is fixedly installed with a fixed top plate, and the top of the fixed top plate is provided with a chute, and the inside of the chute is clamped with five clamps. The inner side below the card frame is fixedly installed with a limit guard. The anti-deviation equipment used in the PVC pipe production line fixes the connecting screw at the right end of the limiting rod at the outlet of the extruder, thereby fixing the top of the limiting rod. When the pipe is extruded, the pipe will be stuck outside the limiting rod , because the limiting pulleys are evenly distributed on the outside of the limiting rod, the sliding friction is changed into rolling friction, which solves the problem of easy scratches caused by using the limiting plate for limiting in the past.

Description

technical field [0001] The invention relates to the technical field of pipe production equipment, in particular to an anti-deviation equipment for a PVC pipe production line. Background technique [0002] PVC pipes are usually produced by extruders. The plastic compounding materials are melted inside the extruder barrel, and then the pipes are extruded according to the appropriate size through the extrusion die. Since the PVC pipe is a slender structure, in During the production process of the extruder, the pipe may deviate from the correct moving direction, causing the pipe to be stuck or even bent due to excessive deviation during the moving process. Usually, it is necessary to install an anti-deviation device Limit to ensure the quality of pipe production. [0003] The existing anti-deviation device usually installs a placing plate with a circular top surface on the bottom of the pipe to limit the pipe. This method can only limit the pipe simply. When restricting some pi...

Problems solved by technology

[0003] The existing anti-deviation device usually installs a placing plate with a circular top surface on the bottom of the pipe to limit the pipe. This method can only limit the pipe simply. When restricting some pipes with larger diameters When the anti-deviation effect is not good, the pipe is easy to break away from the top of the limiting plate, causing the pipe to bend and reducing the quality of the pipe. In addition, the limiting plate at the top of the arc can only limit some fixed-sized pipes. When the size of the pipe changes greatly, because the pipe cannot fully contact with the top of the limiting plate, the pipe will shake during the moving process, further reduced pipe quality
