Description

Technical Field

[0001] The utility model relates to a welding nozzle, in particular to a metal foil installation welding nozzle. Background Art

[0002] Linear low-density polyethylene (LLDPE) sheets are connected and sealed by hot-melt welding after overlapping. The current leak detection technology uses the electric spark leak detection process. Before welding, a metal foil is laid on the overlapping surface. Its function is to use high voltage electricity to hit the foil after welding. If there is a leak or a cold weld, it will generate an electric spark due to the air around the foil, which can be detected. However, the position fixation of the metal foil is relatively poor, and the laying is inconvenient. Utility Model Content

[0003] The utility model aims to provide a metal foil installation welding nozzle, which is convenient for laying metal foil.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a metal foil installation welding nozzle, including a welding machine connecting part and an air outlet nozzle, characterized in that two parallel convex parts are arranged on the air outlet nozzle, a groove structure is formed between the convex parts, one end of the convex part is aligned with the air outlet nozzle, and a fixing component is arranged at the other end, the fixing component is tubular, and connecting heads are respectively arranged on both sides of one end of the fixing component, and a connecting hole is arranged on the convex part near the end of the fixing component, and the connecting head and the corresponding connecting hole can be rotatably connected so that the fixing component can be movably installed on the convex part.

[0005] Further: an inclined surface structure is arranged at the bottom of the fixing component near the welding machine connection part.

[0006] Compared with the prior art, the utility model has the following beneficial effects: the utility model fixes the position of the metal foil through the fixing component and the groove structure, so as to facilitate the laying of the metal foil. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Example 1

[0014] See also Figures 1 to 4 A metal foil mounting welding nozzle comprises a welding machine connection part 1 and an air outlet nozzle part 2. The welding connection part and the air outlet nozzle part are prior arts. The air outlet nozzle part 2 is provided with two parallel convex parts 31, and a groove structure is formed between the convex parts 31. One end of the convex part 31 is aligned with the air outlet nozzle part 2, and a fixing component 32 is provided at the other end. The fixing component 32 is tubular, and connecting heads 32a are respectively provided on both sides of one end of the fixing component 32. The convex part 31 is provided with a connecting hole near the end of the fixing component, and the connecting head 32a and the corresponding connecting hole can be rotatably connected to movably install the fixing component on the convex part.

[0015] In the embodiment, an inclined surface structure 32b is provided at the bottom of the fixing component 32 near the welding machine connection portion. This design facilitates the angle adjustment of the fixing component.

[0016] Figure 5 The figure is a schematic diagram of metal foil laying, in which A is the overlapped plate part, B is the hot melt area, and C is the metal foil. During laying, one end of the metal foil passes through the fixing component 32 and enters the groove between the two protrusions 31, and finally the end of the metal foil slightly extends out of the end of the air outlet nozzle 2. The hot air welding machine works so that the hot air blown out of the air outlet nozzle 2 melts the overlapped surface, and the metal foil is fixed to the middle of the hot melt area on both sides through the pressing rod. As the air outlet nozzle 2 moves, the metal foil to be installed is gradually pressed to the middle position of the hot melt area until the metal foil is laid on the overlapped surface.

[0017] Instructions for use: ① Overlap the PE sheet to ensure that the overlapping parts overlap by 50㎜; ② Use 5mm (5mm width, in sheet form) strip metal foil and select the corresponding welding nozzle fixing parts; ③ Preheat the hot air welding machine for 10-15 minutes (the hot melt temperature can be adjusted according to the temperature requirements); ④ The metal foil passes through the welding nozzle fixing parts and is installed on the welding nozzle; ⑤ Connect the welding nozzle and the welding gun to carry out welding operations, with a welding speed of 45cm / minute; ⑥ Heat dissipation, and welding is completed.

[0018] Example 2

[0019] The difference between the scheme and embodiment 1 is that, in order to facilitate the use of the fixing component, see Figure 6 A first ring is provided at the upper end of the fixing component 32, a second ring is provided at the welding machine connecting part, and a first hook 41a and a second hook 41b are provided at both ends of the retaining ring 41 respectively. The first hook 41a is connected to the first ring, and the second hook 41b is connected to the second ring.

[0020] The above is only a preferred embodiment of the utility model, and the protection scope of the utility model is not limited to the above embodiment. All technical solutions belonging to the principle of the utility model belong to the protection scope of the utility model. For those skilled in the art, several improvements made without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
