step 1: an operator rotates the sleeve 6 clockwise, the sleeve 6 moves towards the direction close to the pipe extruder 2 along the direction of the transverse bearing rod 3, the sleeve 6 drives the mounting block 8 to move together, the mounting block 8 drives the second connecting rod 5 to move, and the second connecting rod 5 drives the first connecting rod 4 to move, so that the inclination angle of the first connecting rod 4 is increased, and the position of the conical plate 10 is adjusted;
step 2: an operator sleeves the mounting pipe 12 on the outer side of the transverse bearing rod 3 and moves the mounting pipe 12 until one end of the mounting pipe 12 is in contact with one side of the stop block 11, and the operator sleeves the fastening block 13 on the outer side of the transverse bearing rod 3 in a threaded manner until the fastening block 13 and the stop block 11 clamp the mounting pipe 12 tightly;
and 3, step 3: an operator starts the pipe extruder 2, the pipe extruder 2 extrudes the pipe body 18, and the first driving shaft 20 and the first driven shaft 21 respectively drive the first traction wheel 22 on the outer side to rotate and push the pipe body 18 to move towards the inside of the first molding pipe 16;
and 4, step 4: the pipe body 18 penetrates through the heating pipe and heats the pipe body 18 through the heating pipe, the pipe body 18 is in contact with the outer side of the conical plate 10, the inner wall of the pipe body 18 moves along the outer side of the conical plate 10, so that the diameter of the pipe body 18 is enlarged, the pipe body 18 continues to move until the outer side of the pipe body 18 is in contact with the inner wall of the first molding pipe 16, and the outer diameter of the pipe body 18 is restrained through the first molding pipe 16;
and 5: the correction tube 15 and the second modeling tube 17 realize the restraint of the inner diameter and the outer diameter of the tube body 18, so that the diameter of the output tube body 18 is integrally consistent, and the tube body 18 continues to move until the tube body 18 passes through the two second traction wheels 31.
