[0020] Example 1

[0021] This embodiment provides an auxiliary tool for treating the joints of PVC floor rolls, such as... Figure 1 As shown, this utility model includes a positioning bracket 1, a mounting shaft 2, two rollers 3, a positioning component 4, a quick-release component 5, and a hot melt welding gun 6 for welding; the mounting shaft 2 is located at the bottom of the positioning bracket 1, the two rollers 3 are respectively located at both ends of the mounting shaft 2, the positioning component 4 is located in the middle of the mounting shaft 2, the quick-release component 5 is located at the top of the positioning bracket 1, and the hot melt welding gun 6 is detachably mounted on the quick-release component 5.

[0022] In this embodiment, the positioning component 4 is set between two PVC rolls for positioning the seam. The end of the manual auxiliary tool is supported by two rollers 3, and the front end is fixed with the hot melt welding gun 6 by the quick-release component 5, so that the positioning component 4 of the manual auxiliary tool can move along the seam, ensuring a smooth overall weld line, reducing construction difficulty, reducing construction intensity, improving worker efficiency and the welding quality of the rolls.

[0023] The positioning bracket 1 has a triangular structure and is symmetrically arranged on both sides. The axis of the hot melt welding gun 6 is located on the plane where the positioning component 4 is located. This ensures the manual auxiliary tool is balanced from left to right and prevents deviation in the direction of travel.

[0024] Example 2

[0025] Based on Example 1, such as Figure 4 As shown, the quick-release assembly 5 includes a first half-hoop 51, a second half-hoop 52, and a rubber pad 53. The first half-hoop 51 is rotatably connected to one side of the second half-hoop 52. The rubber pad 53 is disposed on the inner wall of the first half-hoop 51 and the second half-hoop 52. The first half-hoop 51 is fixedly connected to the top of the positioning bracket 1.

[0026] In this embodiment, the first half-hoop 51 and the second half-hoop 52 are used in combination, which can be adapted to most sizes of hot melt welding guns 6 on the market.

[0027] The second half-clamp 52 is rotatably connected to a connecting stud 54 on its side, and the first half-clamp 51 is provided with a retaining seat 55 on its side. A fastening screw 56 is threaded onto the connecting stud 54. This allows for the quick disassembly and installation of the hot melt welding gun 6.

[0028] Example 3

[0029] Based on Example 1, such as Figure 2 , 3As shown, the positioning assembly 4 includes two position-adjustable positioning discs 41 and an internal thread 42; the middle surface of the mounting shaft 2 is provided with an external thread 21; the internal thread 42 is located in the middle of the positioning discs 41, and the positioning discs 41 are threadedly connected to the mounting shaft 2 through the cooperation of the internal thread 42 and the external thread 21.

[0030] In this embodiment, since the weld seam of PVC roll is generally set between 1.5mm and 5mm, in order to ensure accurate positioning, positioning disk 41 is set to position the two edges of PVC roll respectively, further ensuring accurate positioning. At the same time, the movable positioning disk 41 also facilitates the adjustment of the positioning reference, and facilitates the calibration of manual auxiliary tools after positioning deviation occurs after long-term use.

[0031] The positioning component 4 also includes two hand-tightening screws 46. The sides of the two positioning discs 41 respectively abut against the sides of the two hand-tightening screws 46, and the hand-tightening screws 46 are threaded onto the surface of the external thread 21. The hand-tightening screws 46 can be used in conjunction with the positioning discs 41 to prevent the positioning discs 41 from shaking or shifting.

[0032] The positioning component 4 also includes a mounting groove 44 and a spring 45. The mounting groove 44 is formed on the side of the positioning disk 41, and the spring 45 is disposed in the mounting groove 44 between the two positioning disks 41. By setting the spring 45 between the two positioning disks 41, a supporting force can be provided to the positioning disks 41 when adjusting their positions, so that the positioning disks 41 are accurately positioned and at the same time the positioning disks 41 are securely fastened.

[0033] The positioning disc 41 has a guide edge 43 on its edge. The thickness of the guide edge 43 does not exceed 0.75mm to prevent the two guide edges 43 from failing to fit together even when fully aligned.

[0034] Implementation steps:

[0035] 1. Welding gun adapter installation: Open the quick-release assembly 5 and insert the hot melt welding gun 6 into the half-clamp cavity; tighten the fastening screw 56 to deform the rubber pad 53 to complete the clamping;

[0036] 2. Adjustment of positioning components: Rotate the positioning disk 41 to the target distance according to the designed seam width (1.5-5mm) to ensure that the overlap error between the hot melt welding gun 6 and the midplane of the positioning component 4 is ≤0.2mm;

[0037] 3. Joint positioning calibration: Embed the positioning plate 41 into both sides of the joint of the roll material to be welded; push the tool to run for 3-5cm and observe the fit between the guide edge 43 and the edge of the roll material; fine-tune the positioning plate 41 and the hand screw 46 to eliminate lateral offset and ensure straight-line travel accuracy;

[0038] 4. Continuous welding implementation: Maintain constant thrust to make roller 3 advance at a uniform speed; monitor the welding gun angle in real time through quick-release component 5 and maintain an inclination angle of 70-80°; stop the machine to check the weld penetration depth after every 10 meters of welding.
