Automatic winding device for extrusion molding plastic pipe

The invention discloses an automatic winding device for an extrusion-molded plastic pipe. The automatic winding device comprises a rack and a PLC (Programmable Logic Controller) mounted on the rack, wherein a winding displacement assembly and a winding device used for winding a pipe are mounted on the rack, and the winding displacement assembly is used for guiding the pipe, so that the pipe is uniformly wound on the winding device; a central control rod movably connected with the winding device is further installed on the machine frame, and an automatic packaging mechanism is installed on the central control rod and the machine frame. The winding device is located between the automatic packaging mechanism and the rack. A limiting structure used for limiting the pipe is installed at the end, away from the rack, of the center control rod. Through the arrangement of the automatic packaging mechanism, after the winding device completes winding of the pipes, the pipes can be automatically packaged, and therefore t
