Description

Technical Field

[0001] The utility model relates to the technical field of welding gun boots, in particular to a polyethylene welding gun boot with adjustable angle. Background Art

[0002] The polyethylene welding gun boot is an important tool used in conjunction with the welding gun during the polyethylene material welding process. Its main function is to protect the welding nozzle of the welding gun and ensure the smooth progress of the welding process. By controlling the welding temperature and airflow, the gun boot can effectively improve the uniformity and quality of the welding and reduce weld defects.

[0003] When the welding gun is used in conjunction with the gun shoe for welding, if the fixed angle of the welding shoe is too large or too small, the welding gun will inevitably vibrate, slide, and other phenomena when moving, affecting the quality of welding. In particular, critical welds have sealing requirements. If a problem occurs, subsequent investigation and repair will be very difficult. Utility Model Content

[0004] The utility model provides a polyethylene welding gun shoe with adjustable angle, which solves the problems raised by the above background technology.

[0005] In order to solve the above technical problems, the technical solutions of the present utility model are as follows:

[0006] An embodiment of the present utility model provides a gun shoe for a polyethylene welding gun with adjustable angle, comprising: a gun shoe body, a surface of the gun shoe body fixedly connected to a connecting shaft, a surface of the connecting shaft rotatably connected to two rotating plates, surfaces of the two rotating plates are rotatably connected to a driving plate, a surface of the gun shoe body fixedly connected to two fixed plates, surfaces of the two fixed plates are fixedly connected to an adjusting caliper, an inner wall of the adjusting caliper is rotatably connected to a bidirectional screw, the driving plate is slidably connected to the adjusting caliper, a surface of the bidirectional screw is threadedly connected to two rings, and the two rings are slidably connected to the driving plate

[0007] Through the above technical solution, by rotating the bidirectional screw, the ring can drive the two drive plates to move to both sides, thereby adjusting the position and angle of the connecting plate to achieve the effect of adapting to different positions.

[0008] Furthermore, two baffles are slidably connected to the surface of the driving plate, and an insertion rod is slidably connected to the surface of the driving plate, and both of the baffles are fixedly connected to the insertion rod.

[0009] Through the above technical solution, the baffle can cover the chute at the driving plate position when the fixed angle is not adjusted, so that foreign matter will not enter the chute.

[0010] Furthermore, a spring is sleeved on the surface of the insertion rod, and two ends of the spring are fixedly connected to the insertion rod and the driving plate respectively.

[0011] Through the above technical solution, the spring can self-adaptively adjust the adjustment distance of the baffle without the need for manual operation by the staff.

[0012] Furthermore, an anti-slip sleeve is glued to the surface of the bidirectional screw, and the arc surface of the anti-slip sleeve has a plurality of protrusions in a circumferential array.

[0013] Through the above technical solution, the protrusions on the mating surface of the anti-slip sleeve can increase the friction with the hands of the staff, thereby facilitating the driving of the bidirectional screw.

[0014] Furthermore, a marking block is fixedly connected to the surface of the driving plate, and the cross section of the marking block is triangular.

[0015] Through the above technical solution, the marking block can help staff understand the size of the adjusted distance and angle.

[0016] Furthermore, an elastic rope is fixedly connected to the surface of the gun boot body, a pull strip is fixedly connected to the surface of the elastic rope, a push rod is slidably connected to the surface of the elastic rope, and a slot is provided on the surface of the push rod.

[0017] Through the above technical solution, the push rod can push out and clean the polyethylene inside the gun boot body after welding is completed, and it will not solidify, thereby reducing the efficiency of subsequent glue injection. The elastic rope is inserted into the slot to achieve stable positioning of the push rod.

[0018] Furthermore, both ends of the push rod are fixedly connected with auxiliary blocks, and the cross-section of the auxiliary blocks is trapezoidal.

[0019] Through the above technical solution, the auxiliary block facilitates the staff to quickly connect to the output position of the gun boot body when the push rod is performing cleaning work.

[0020] The above solution of the utility model includes at least the following beneficial effects:

[0021] 1. The utility model increases the practicability of the gun shoe body by arranging a bidirectional screw in conjunction with a circular ring to drive the driving plate and the rotating plate to adjust the fixed angle, so that the gun shoe body will not vibrate when welding in different places, which will affect the quality. There is no need to frequently replace the gun shoe of the welding gun, which increases the convenience of welding work. The weld seal is more stable and does not require later inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

The surface of the driving plate 4 is slidingly connected to two baffles 10, and the surface of the driving plate 4 is slidingly connected to the plug rod 11. The two baffles 10 are fixedly connected to the plug rod 11. The baffle 10 can cover the chute at the position of the driving plate 4 when the fixed angle is not adjusted, so that foreign matter will not enter the chute. The surface of the plug rod 11 is covered with a spring 12, and the two ends of the spring 12 are respectively connected to the plug rod 11 and the driving plate 4 fixed connection, the spring 12 can self-adapt to adjust the adjustment distance of the baffle 10, and does not require manual operation by the staff. The surface of the bidirectional screw 7 is glued with an anti-slip sleeve 13, and the arc surface circumferential array of the anti-slip sleeve 13 has several protrusions. The protrusions on the matching surface of the anti-slip sleeve 13 can increase the friction with the staff's hand, thereby facilitating the driving of the bidirectional screw 7. The surface of the drive plate 4 is fixedly connected with a marking block 9. The cross-section of the marking block 9 is triangular. The marking block 9 can facilitate the staff to understand the size of the adjusted distance and angle. The surface of the gun boot body 1 is fixedly connected with an elastic rope 16. The elastic rope The surface of 16 is fixedly connected with a pull strip 17, and the surface of the elastic rope 16 is slidably connected with the push rod 14.

At the same time, the bidirectional screw 7 is rotated in the opposite direction to adjust the rotation angle to the minimum. At this time, the baffle 10 will be affected by the spring 12 to cover the sliding groove on the surface of the drive plate 4.
