NOVELTY - Reinforced rigid polyvinyl chloride cable pipe comprises 100-150 pts. wt. polyvinyl chloride resin, 5-30 pts. wt. coupling agent, 0.1-15 pts. wt. modifying white graphene, 5-40 pts. wt. filler, 0.1-10 pts. wt. heat stabilizer, and 0.5-15 pts. wt. lubricant, where he reinforced rigid polyvinyl chloride cable pipe is prepared by (1) providing each raw material and adding to a high mixer to obtain a mixture, (2) drying the mixture n a vacuum drying box to obtain a pre-made powder, and (3) adding the pre-formed powder into the hopper, introducing the pre-formed powder into the vertical extrusion barrel through the pipe, extruding the pre-formed powder from the bottom of the vertical extrusion barrel into the horizontal extrusion barrel by the first screw, during the extrusion process, heating the cast aluminum heating sheet of the pre-formed powder in the horizontal extrusion barrel, blowing outside air using two blowers into the upper casing, cooling and cooling the upper casing. USE - Used as reinforced rigid polyvinyl chloride cable pipe. ADVANTAGE - The method: solves the complex structure of the fixed-length cutting device. DETAILED DESCRIPTION - Reinforced rigid polyvinyl chloride cable pipe comprises 100-150 pts. wt. polyvinyl chloride resin, 5-30 pts. wt. coupling agent, 0.1-15 pts. wt. modifying white graphene, 5-40 pts. wt. filler, 0.1-10 pts. wt. heat stabilizer, and 0.5-15 pts. wt. lubricant, where he reinforced rigid polyvinyl chloride cable pipe is prepared by (1) providing each raw material and adding to a high mixer to obtain a mixture, (2) drying the mixture n a vacuum drying box to obtain a pre-made powder, (3) adding the pre-formed powder into the hopper, introducing the pre-formed powder into the vertical extrusion barrel through the pipe, extruding the pre-formed powder from the bottom of the vertical extrusion barrel into the horizontal extrusion barrel by the first screw, during the extrusion process, heating the cast aluminum heating sheet of the pre-formed powder in the horizontal extrusion barrel, blowing outside air using two blowers into the upper casing, cooling and cooling the upper casing, forming the preformed powder into a preformed tube through a die through horizontal extrusion, where the three conveyor tracks hold the preformed tube, and the third motor drives the conveyor track to convey the preformed tube, then blowing the blower below the cooling box air into the cooling box, and then blowing the cold air from the ice box to the surface of the preformed tube and cooling the preformed tube to form a semi-finished tube, and (4) transmitting the semi-finished product tube from the fixing ring on the other side through the inlet to the cable pipe, periodically cutting the cutting blade at the bottom of the lifting plate to the semi-finished tube to obtain the finished reinforced rigid polyvinyl chloride cable pipe, where the drive shaft rotates the first bevel gear rotates, the first bevel gear meshes and the second bevel gear rotates, and the second bevel gear drives the sheave through the connecting rod, the sheave periodically drives the crank to rotate, the crank drives the support rod to rotate, and the support rod drives the top cable base support to rotate, and the tube pushes the finished reinforced rigid PVC cable pipe on the cable pipe base from the outlet to obtain the finished reinforced rigid polyvinyl chloride cable pipe.
