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.
