Production device of polyethylene pipeline

The utility model discloses a polyethylene pipeline production device which comprises a mounting base, and two supporting frames are fixedly connected to the upper surface of the mounting base. A servo motor is started, an output shaft of the servo motor drives a threaded rod to rotate, so that a threaded moving block drives a fixed mounting strip to move, a plurality of pushing plates push a pipeline to move, one end, far away from the pushing plates, of the pipeline enters two guide plates to be positioned, a first lifting air cylinder is started, and the pipeline is driven by the first lifting air cylinder to move. The piston end of a first lifting air cylinder drives a plurality of pressing blocks to descend through a fixing plate, so that the pressing blocks press the pipeline, then a second lifting air cylinder is started, the piston end of the second lifting air cylinder drives a cutter to descend, so that the cutter cuts off the pipeline, after cutting is completed, a pushing plate pushes the pipeline
