The support fixing components include a slide rail box 3, a screw 4, a moving sleeve block 5, a support frame 6 and a fixing roller 7.

[0025] Two slide rail boxes 3 are symmetrically fixed to the top surface of the support base 1 on the side of the heater 2. Each slide rail box 3 is rotatably connected to a lead screw 4 through a bearing. Each lead screw 4 is symmetrically threaded with a movable sleeve 5. Each movable sleeve 5 on the lead screw 4 has a threaded hole that mates with the lead screw 4. The threads of the two movable sleeve 5 on each lead screw 4 are opposite in direction. The ends of every two movable sleeves 5 extending to the outside of the slide rail box 3 are fixed to the bottom surface of the support frame 6. Each support frame 6 has a fixed roller 7 inside. The rear end of each set of two lead screws 4 is fixed with a driven roller. The wheel is connected to the two driven wheels by a belt 10. A protective box 9 is fixed between the two slide rail boxes 3 on the outer side of each belt 10. One end of the lead screw 4 extends to the rear side of the slide rail box 3 and is fixed to the output end of the servo motor 8. The servo motor 8 is mounted on the rear side wall of the lead screw 4. Another protective box 9 is fixed between the two adjacent slide rail boxes 3 in the two lower support and fixing components. The two adjacent lead screws 4 are connected to the driven wheels by another belt 10. The two upper support and fixing components are connected to the two lower support and fixing components in a liftable manner.

[0026] To drive the upper lead screw 4 to rotate via the servo motor 8, bevel gear 11 is fixed to one end of each of the four lead screws 4 extending to the rear side of the slide rail box 3. The bottom of the two lower bevel gears 11 is meshed with bevel gear 2 12, and the bottom of the bevel gear 2 12 is rotatably connected to the top surface of the fixed plate 18 via bearings. The fixed plate 18 is fixed to the rear wall of the support base 1. The top of each of the two bevel gear 2 12 is fixed with a guide rod 14, and the outer surface of the guide rod 14 is symmetrically fixed with limit blocks 15. The top of the two upper bevel gears 11 is meshed with a bevel gear 3 13, and each bevel gear 3 13 is slidably sleeved on the guide rod 14 and the limit block 15. The top of each of the two bevel gear 3 13 is fixed with a support cylinder 16, and a support plate 17 is rotatably sleeved on the support cylinder 16. The two support plates 17 are fixed to the top surface of the upper slide rail box 3. The diameters of the bevel gears 11, 2 12 and 3 13 are equal.

[0027] When fixed, in order to ensure that the fixed roller 7 can support the PE pipe, the diameter of the fixed roller 7 is greater than the height inside the support frame 6. The front edge of the heater 2 is fixed with a handle, and the distance between the two support frames 6 is greater than the thickness of the heater 2. The bevel gear 13 is provided with a sliding hole that cooperates with the guide rod 14. The sliding hole is provided with a rectangular groove that cooperates with the limit block 15 on both sides. This ensures that when the guide rod 14 and the limit block 15 rotate, the bevel gear 13 can be driven to rotate, and at the same time, it will not affect the sliding of the bevel gear 13 on the guide rod 14. Meanwhile, the support cylinder 16 is set as a hollow T-shape to facilitate the rotation of the guide rod 14 and the limit block 15 inside the support cylinder 16.

[0029] The operating method and working principle of this device are as follows: During welding, first adjust the distance between the two fixed rollers 7 according to the diameter of the PE pipe to be welded. Turn on the servo motor 8, which drives the lead screw 4 to rotate. When the lead screw 4 rotates, it drives the bottom lead screw 4 to rotate simultaneously through the protective box 9. During rotation, the two moving sleeves 5 on each lead screw 4 move in opposite directions, adjusting the distance between the two fixed rollers 7. While the outer lead screw 4 rotates, it drives the bevel gear 11 to rotate. The bevel gear 11 drives the meshing bevel gear 2 12 to rotate. When the bevel gear 2 12 rotates, it drives the transmission rod 14 and the limiting block 15 to rotate, thereby driving the bevel gear 3 13 it is fitted with to rotate. When the bevel gear 3 13 rotates, it drives the upper bevel gear 11 to rotate, which in turn drives the upper lead screw 4 to rotate, thus adjusting the distance between the two fixed rollers 7. After adjusting the distance between the two fixed rollers 7 in each upper group, place a PE pipe between the two fixed rollers 7 below. Rotate the handle 21 on this side to rotate the adjusting screw 19. When the adjusting screw 19 rotates, it causes the upper fixed roller 7 to move down and clamp the PE pipe. Then, place another PE pipe on top of the other fixed roller 7 so that the opposite sides of the two PE pipes are in contact with the side of the heater 2. Turn on the heater 2 to heat the end of the PE pipe. After heating, rotate the heater 2 to move it out between the two PE pipes and push the unfixed PE pipe to fit against the end of the fixed PE pipe, so that the two are fused and welded. Then, rotate the handle 21 above the unfixed pipe to clamp the pipe with the upper fixed roller 7. After the two pipes are fixed, rotate the two handles 21 in the opposite direction to remove the two welded pipes.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
