Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material auxiliary equipment production, in particular to a polymer roof patch welding device, a hot melt patch and an adsorption device. Background Art

[0002] Traditionally, steel roof waterproofing membranes have relied on mechanical perforation for installation. In recent years, a flexible plastic gasket has emerged. During installation, hot air partially melts the waterproofing membrane and gasket, ensuring a perfect fit without gaps, thus resolving leaks in steel roofs.

[0003] The utility model patent application, publication number CN221392330U, with a publication date of July 23, 2024, discloses an automatic welding device for waterproof hot-melt patches, comprising a drive unit comprising a rotating frame, a drive wheel, and a drive unit; a heating unit comprising a hot air gun; and a connecting shaft, wherein the heating unit is connected to the drive unit via the connecting shaft. The drive unit drives the drive wheel to rotate, thereby driving the heating unit connected to the drive unit to move, so that the hot-melt patch in the receiving groove and the waterproof membrane are bonded. The main technical effect is that the drive unit of the drive unit drives the drive wheel inside the rotating frame to rotate, thereby causing the flexible patch located in the receiving groove to rotate with the drive wheel. At the same time, the hot air gun provided in the heating unit connected to the drive unit via the connecting shaft synchronously heats the flexible gasket and the waterproof membrane, and cooperates with the rotation of the drive wheel to weld the flexible gasket and the waterproof membrane, thereby replacing manual welding, greatly reducing manual labor and improving welding efficiency.

During welding, the operator cannot accurately control the heating time of the patch, resulting in insufficient heating of the patch and the coil, and insufficient welding strength. Therefore, a polymer roof patch welding device, a hot melt patch and an adsorption device are proposed, aiming to solve the problem in the prior art that the operator cannot accurately control the heating time of the patch, resulting in insufficient heating of the patch and the coil, and insufficient welding strength.

The buzzer 7 is magnetically connected to the first magnetic block 5. The magnetic force of the buzzer 7 can be increased by the first magnetic block 5, thereby increasing the volume of the buzzer 7 when it sounds, so that the operator can better obtain the timing information.

[0029] As a further embodiment provided by the present invention, Figure 3 and Figure 2 As shown, the welding nozzle 2 includes a connecting end 21, a first air outlet 22 and a second air outlet 23. The first air outlet 22 and the second air outlet 23 are respectively connected to the connecting end 21. The welding nozzle 2 is connected to the output end of the hot air gun body 1 through the connecting end 21. The first air outlet 22 and the second air outlet 23 are respectively located on the upper and lower sides of the connecting end 21. The welding nozzle 2 has a "T"-shaped structure as a whole.

[0033] A support portion 9 is provided in the cavity 81 provided inside the patch body 8. After the patch body 8 is hot-melt welded to the waterproof membrane, the exposed screws are located inside the support portion 9. Wrapping the screws with the support portion 9 can enhance the protection effect on the screws and prevent the screws from being damaged. At the same time, since the patch body 8 and the waterproof membrane are hot-melt welded, they have a good waterproof effect, which can provide waterproof protection for the screws, as well as good strength protection for the screws, thereby reducing the number of maintenance times.

The second magnetic block 13 can adsorb the support portion 9 inside the patch body 8, so that the patch body 8 can be located inside the accommodating portion 11. The operator can use the holding portion 10 to move the patch body 8 to the top of the welding nozzle 2 for heating by the hot air blown out by the first air outlet 22.

[0036] The second magnetic block 13 installed on the accommodating portion 12 opened inside the accommodating portion 11 can adsorb the support portion 9 inside the accommodating portion 11, and then the accommodating portion 11 can be moved by the holding portion 10 while driving the patch body 8 to move, which facilitates welding and improves welding efficiency.

[0037] Working principle:

[0038] The staff uses the gripping part 10 to absorb a new patch body 8 through the second magnetic block 13 provided inside the accommodating part 11, and places the preheated hot air gun body 1 near the screw to be welded, so that the screw is located below the second air outlet 23 of the welding nozzle 2.

[0039] Then place the patch body 8 inside the accommodating portion 11 above the first air outlet 22 of the welding nozzle 2, start the switch 6, and the timer 4 starts timing. After the heating time is reached, remove the hot air gun body 1 and use the grip 10 to weld the patch body 8 to the waterproof membrane.
