The joint is located directly below the hot air gun 8. Then, the drive motor is controlled to drive the drive gear 11 to rotate, which in turn drives the rotating outer sleeve 4 to rotate, thereby causing multiple driven gears 26 and screws 25 to rotate. Under the action of the guide rod 30, the moving sleeve 27 drives the clamping block 28 to move until the plastic tubes 3 are clamped. Then, the locking bolt 36 is rotated to allow rotation between the rotating inner sleeve 2 and the fixed sleeve 16. Then, the drive motor is started. The machine can rotate the outer sleeve 4 to drive the inner sleeve 2 to rotate, thereby causing the plastic tube 3 to rotate. During the rotation of the plastic tube 3, the hot air spray gun 8 is activated, and then the operator holds the plastic welding rod to perform plastic welding. When the welded area passes through the forming groove 22, the forming roller 21 will roll the welded area. Under the action of friction, the rotation of the plastic tube 3 will drive the passive rotating wheel 19 to rotate. When the passive rotating wheel 19 rotates, it drives the internal gear 34 to rotate intermittently, thereby causing the intermittent rotating wheel 20 to rotate intermittently, so that different forming rollers 21 are switched to roll the welded part.
