[0002] A hot air welding gun is a common tool in string welders, primarily used for welding and repairing thermoplastic materials. The nozzle is a crucial component of a hot air welding gun and directly impacts welding quality and efficiency. Hot air welding gun nozzles come in a variety of styles, each suited to different welding needs. Round nozzles are suitable for spot welding and localized welding, often used for thin films or small areas. Flat nozzles are ideal for large-area welding, providing uniform heating over larger weld surfaces. Duct nozzles, used for pipe welding, are shaped like pipes to better adapt to the weld object.

[0003] Currently, the traditional hot air welding gun nozzle is not equipped with a replaceable mechanism, which makes it impossible to meet different welding requirements. In addition, the entire equipment needs to be replaced to meet the welding requirements, which is cumbersome to operate and reduces welding efficiency. Therefore, improvements are needed.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] See also Figure 1-Figure 4 The utility model provides a technical solution: a hot air welding gun nozzle of a string welding machine, comprising a workbench 1 and a welding nozzle body 18, a support column 2 is symmetrically fixedly installed on the bottom of the workbench 1, an L-plate 3 is fixedly installed on the top of the workbench 1, a connecting column 4 is fixedly installed on the top bottom side of the L-plate 3, a hot air blower 5 is fixedly installed on the bottom end of the connecting column 4, a pipe 6 is fixedly installed on the input end of the hot air blower 5, and a pipe 2 is fixedly installed on the output end of the hot air blower 5, an electric telescopic rod 18 is fixedly installed on the bottom of the workbench 1, and a connecting plate 9 is fixedly installed on the output end of the hot air blower 5, a fixing column 10 is symmetrically fixedly installed on the top of the connecting plate 9, a material plate 11 is fixedly installed on the top of the fixing column 10, a fixing ring 12 is fixedly installed on the outer wall of the pipe 2 7, a frame 13 is symmetrically fixedly installed on the outer wall of the fixing ring 12, a threaded rod 14 is rotatably connected to the inside of the frame 13, and the outer wall of the threaded rod 14 is threadedly connected to the connecting frame 15, a clamping ring 16 is fixedly installed on the end of the connecting frame 15 away from the frame 13, and a knob 17 is fixedly installed on one end of the threaded rod 14.

[0025] By turning the knob 17 in sequence, the threaded rod 14 is driven to rotate inside the frame 13. During the rotation, the threaded rod 14 will drive the connecting frame 15 to slide inside the frame 13. During the sliding process, the connecting frame 15 will drive the clamping ring 16 to move together. After moving a certain distance, the clamping ring 16 will release the restriction on the welding nozzle body 18. After the restriction is released, the welding nozzle body 18 will slide down along the outer wall of the pipe 2 7. After sliding, the welding nozzle body 18 of another specification will slide upward along the outer wall of the pipe 2 7. After sliding the limit distance, the knob 17 is turned in sequence so that the two sets of clamping rings 16 clamp and fix the welding nozzle body 18. This design realizes the function of quick disassembly and replacement of the welding nozzle body 18, so that it can meet different welding requirements, and effectively avoids the need to replace the entire equipment when welding different types of objects.

[0026] like Figure 1 and Figure 4 As shown, the fixed column 10 is slidably connected to the workbench 1, and the connecting frame 15 is slidably connected to the frame 13. The sliding connection between the fixed column 10 and the workbench 1 improves the up and down adjustment effect of the storage plate 11, and the sliding connection between the connecting frame 15 and the frame 13 improves the limiting effect of the connecting frame 15 during adjustment.

[0027] like Figure 4 As shown, the clamping ring 16 is slidably connected to the welding nozzle body 18, and the welding nozzle body 18 is slidably connected to the pipe 2 7. The sliding connection between the clamping ring 16 and the welding nozzle body 18 improves the fixing effect of the welding nozzle body 18, and the sliding connection between the welding nozzle body 18 and the pipe 2 7 improves the disassembly and assembly efficiency of the welding nozzle body 18.

[0028] like Figure 4 As shown, a sealing groove 20 is provided at the bottom of the fixing ring 12, and a sealing ring 19 is fixedly installed on one end of the welding nozzle body 18 close to the fixing ring 12. The sealing ring 19 is slidably connected to the sealing groove 20. The sliding connection between the sealing ring 19 and the sealing groove 20 improves the sealing effect between the welding nozzle body 18 and the pipe 2 7.

[0029] like Figure 5-Figure 6As shown, a shell 21 is fixedly installed on the outer wall of the pipe 1 6, and an insert frame 22 is slidably connected to the interior of the shell 21. A filter screen 23 is fixedly installed inside the insert frame 22. A long plate 24 is fixedly installed on the top of the insert frame 22. Limiting holes 25 are symmetrically provided on the long plate 24 and the top of the shell 21. A fixing frame 26 is fixedly installed on the top of the L-plate 3. An electric telescopic rod 27 is fixedly installed on the bottom side of the top of the fixing frame 26. The output end of the electric telescopic rod 27 is fixedly installed on a bottom plate 28. The bottom of the bottom plate 28 is symmetrically fixed with limiting columns 29. The filter screen 23 improves the filtering effect of the air entering the hot air blower 5, effectively preventing impurities in the air from entering the hot air blower 5. At the same time, when the filter 23 is clogged, the electric telescopic rod 27 can be started, and the bottom plate 28 can be driven upward by the electric telescopic rod 27. During the upward movement, the bottom plate 28 will drive multiple groups of limit posts 29 to move upward together. After moving a certain distance, the limit posts 29 will be away from the limit holes 25. After moving away, the long plate 24 will be pulled upward, and the insertion frame 22 will be driven to slide upward inside the shell 21 through the long plate 24. During the upward sliding process of the insertion frame 22, the filter 23 will be driven upward together. After moving a certain distance, the filter 23 can be taken out for cleaning, thereby improving the disassembly and cleaning efficiency of the filter 23 and facilitating the operation of the operator.

[0030] like Figure 6 As shown, a sealing gasket 30 is fixedly installed at the bottom of the long plate 24, and a sealing groove 2 31 is opened at the top of the shell 21. The sealing groove 2 31 and the sealing gasket 30 are slidingly connected. The sliding connection between the sealing groove 2 31 and the sealing gasket 30 improves the sealing effect between the long plate 24 and the shell 21.

[0031] like Figure 6 As shown, the limiting column 29 is slidably connected to the limiting hole 25 , and the sliding connection between the limiting column 29 and the limiting hole 25 improves the fixing effect between the long plate 24 and the shell 21 .

[0032] The working principle of this embodiment is as follows: when in use, first place the items to be welded on the storage plate 11, and then start the electric telescopic rod 8 after placement. The electric telescopic rod 8 drives the connecting plate 9 to move upward. In the process of moving upward, the connecting plate 9 will drive multiple groups of fixed columns 10 to slide upward inside the workbench 1. In the process of sliding upward, the multiple groups of fixed columns 10 will drive the storage plate 11 and the items to move upward together. After moving a certain distance, the items on the storage plate 11 will fit with the welding nozzle body 18. After fitting, the electric telescopic rod 8 is closed, and then the hot air blower 5 is started again. When the hot air blower 5 is working, it will inhale air through the pipe 16. After entering the hot air blower 5, it will be heated to the required temperature by the heating element. The heated air is released into the interior of the welding nozzle body 18 through the pipe 2 7. The released hot air will blow from the welding nozzle body 18 to the surface of the item, thereby welding the item. When the hot air blower 5 is working, it will inhale air through the pipe 1 6, and the inhaled air will pass through the filter 23. When passing through, the filter 23 will filter impurities in the air. When the filter 23 is blocked, the electric telescopic rod 27 can be started, and the electric telescopic rod 27 can be used to drive the bottom plate 28 to move upward. During the upward movement, the bottom plate 28 will drive multiple groups of limiting columns 29 to move upward together. After moving a certain distance, the limiting columns 29 will move away from the limiting holes 25. After moving away, the long plate 24 will be pulled upward, and the insertion frame 22 will be driven to slide upward inside the shell 21 through the long plate 24. During the upward sliding process of the insertion frame 22, the filter 23 will be driven upward together. After moving a certain distance, the filter 23 can be taken out for cleaning, thereby improving the disassembly and cleaning efficiency of the filter 23 and facilitating the operation of the operator. When it is necessary to replace welding nozzle bodies 18 of different specifications according to different types of objects, first turn the knob 17 in sequence, and the knob 17 drives the threaded rod 14 to rotate inside the frame 13. During the rotation, the threaded rod 14 drives the connecting frame 15 to slide inside the frame 13, and the connecting frame 15 drives the clamping ring 16 to move together during the sliding process. After moving a certain distance, the clamping ring 16 will release the restriction on the welding nozzle body 18. After the release, the welding nozzle body 18 will slide down the outer wall of pipe 2 7. After sliding, the welding nozzle body 18 of another specification will slide upward along the outer wall of pipe 2 7. After sliding the limit distance, turn the knob 17 in sequence so that the two sets of clamping rings 16 clamp and fix the welding nozzle body 18. This design realizes the quick disassembly and replacement function of the welding nozzle body 18, thereby making it able to meet different welding requirements and effectively avoiding the need to replace the entire equipment when welding different types of objects.The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
