Polyolefin plastic steel reinforced winding pipeline production line and production process

The invention relates to a polyolefin plastic steel reinforced winding pipeline production line which comprises a steel belt unwinding mechanism, a plastic material melting mechanism, a belt material forming mechanism, a cooling mechanism, an adhesive coating mechanism and a winding mechanism. Mounting blocks are slidably arranged on the mounting disc in the axial direction perpendicular to the mounting disc, the sliding blocks correspond to the mounting blocks one to one, the mounting shafts correspond to the sliding blocks one to one, the two ends of each mounting shaft are connected with the corresponding sliding block and the corresponding mounting block respectively, each mounting shaft is coaxially and rotationally sleeved with a guide roller, and a spiral groove is formed in the side wall of each guide roller. And the strip pressure transferring assembly is used for pressing the steel-plastic composite strip on one of the guide rollers and driving the strip to move. The device has the advantages that p
