Description

Technical Field

[0001] This utility model relates to the field of welding machines, and in particular to a multi-angle adjustable welding machine hot air gun bracket. Background Technology

[0002] Hot air welding machine is a special equipment used for welding waterproof membrane. It is widely used in water conservancy projects, municipal engineering, building waterproofing and other fields. It mainly uses hot air to heat the waterproof membrane (such as PVC, PE, EVA and other materials) to melt it and then weld it together to form a sealed waterproof structure.

[0003] In practical applications, hot-melt welding of the coil material is mainly achieved through contact and heat fusion between the hot air gun and the coil material. The tightness of the contact between the hot air gun and the coil material directly affects the welding effect. Existing hot air guns generally only rotate around a pivot point. This rotation is used to switch the welding machine between working and non-working states, and lacks adjustment capabilities (suitable only for two identical and flat coil materials). They cannot handle certain special welding environments and conditions, nor can they meet the requirements of irregularly shaped coil materials (such as those with height differences or sloped surfaces). Summary of the Invention

[0004] To solve the above problems, a multi-angle adjustable welding gun bracket was specially manufactured. This structure enables multi-angle adjustment of the air gun, which can adapt to hot melt welding of various coil specifications.

[0005] To achieve the above objectives, the present invention provides a multi-angle adjustable welding machine hot air gun bracket, comprising a hot air gun and a bracket. One end of the bracket is connected to the welding machine via a rotating shaft, and the other end of the bracket is connected to the hot air gun. The bracket includes a fixed swing arm and a movable swing arm. The fixed swing arm is fixedly mounted on the rotating shaft, and one end of the movable swing arm is rotatably mounted on the rotating shaft. The fixed swing arm has a first mounting hole, and the movable swing arm has a first adjusting waist hole. A bolt passes through the first adjusting waist hole and connects to the first mounting hole.

[0006] Furthermore, a second mounting hole is provided on the other end of the movable swing arm, and a retaining ring is installed on the second mounting hole. The movable swing arm is connected to the air gun through the retaining ring. A third mounting hole is provided on the retaining ring, and the retaining ring is connected to the movable swing arm by bolts and nuts.

[0007] Furthermore, the air gun includes an air gun body and a gun head. A connecting plate is provided at one end of the gun head. The connecting plate is provided with several second adjustment waist holes. Several third mounting holes corresponding to the second adjustment waist holes are provided at the connection between the air gun body and the gun head. Bolts pass through the second adjustment waist holes and connect with the third mounting holes.

[0008] Furthermore, the gun head also has a protective shield that serves a protective function.

[0009] Furthermore, the connecting plate is provided with several columns, and the surface of the columns is provided with threaded holes. The protective cover is fixedly installed on the columns.

[0010] The advantages of this utility model are:

[0011] This bracket allows for at least three dimensions of angle adjustment for the air gun: a first adjustment dimension where the air gun swings around the pivot axis, a second adjustment dimension where it swings around the second mounting hole, and a third adjustment dimension where the air gun rotates around its own axis. These three dimensions of adjustment ensure that the air gun nozzle and the welding coil are fully in contact, thus guaranteeing welding quality.

[0012] The air gun has a split structure consisting of the air gun body and the gun head. When the air gun malfunctions or needs maintenance, it can be carried out separately, which improves maintenance efficiency and reduces maintenance costs. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] A multi-angle adjustable welding gun holder includes a hot air gun and a holder. One end of the holder is connected to the welding machine via a rotating shaft 2, and the other end is connected to the hot air gun. The holder includes a fixed swing arm 7 and a movable swing arm 4. The fixed swing arm 7 is fixedly mounted on the rotating shaft 2, and one end of the movable swing arm 4 is rotatably mounted on the rotating shaft 2. The fixed swing arm 7 has a first mounting hole 13, and the movable swing arm 4 has a first adjusting slot 3. A bolt passes through the first adjusting slot 3 and connects to the first mounting hole 13. The other end of the movable swing arm 4 has a second mounting hole 14, on which a retaining ring 9 is installed. The movable swing arm 4 is connected to the hot air gun via the retaining ring 9. The retaining ring 9 has a third mounting hole 5, and the retaining ring 9 is connected to the movable swing arm 4 via bolts and nuts. The air gun includes a main body 1 and a nozzle 8. A connecting plate 10 is provided on one end of the nozzle 8. The connecting plate 10 has several second adjustment holes 11. Several third mounting holes 5 corresponding to the second adjustment holes 11 are provided at the connection point between the main body 1 and the nozzle 8. Bolts pass through the second adjustment holes 11 and connect to the third mounting holes 5. A protective cover 6 also exists on the outside of the nozzle 8. Several uprights 12 are provided on the connecting plate 10. Threaded holes are provided on the surface of the uprights 12, and the protective cover 6 is fixedly installed on the uprights 12.

[0021] The actual usage method is as follows:

[0022] The bracket includes three different angle adjustment methods, which will be explained one by one below.

[0023] The first angle adjustment method: with the rotating shaft 2 as the axis, the air gun swings up and down. The specific operation method is to loosen the bolt connecting the first adjustment waist hole 3 and the first mounting hole 13, adjust the up and down swing angle of the air gun, and then tighten the bolt again.

[0024] The second angle adjustment method: The air gun rotates around the first mounting hole 13 as the axis. The specific operation method is to loosen the bolt connecting the second mounting hole 14 and the third mounting hole 5, adjust the angle of the air gun, and then tighten the bolt again.

[0025] The third angle adjustment method: The air gun rotates around its own center axis. The specific operation method is to loosen the bolt in the second adjustment waist hole 11. There are usually several second adjustment waist holes 11. All bolts need to be loosened. After adjusting the rotation angle of the gun head 8, tighten the bolts again.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects.
