Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to hot-air welding equipment for airship capsules. Background Art

[0002] Hot air welding is a method of using preheated compressed air or inert gas to heat plastic weldments and electrodes to make them viscous and perform welding under low pressure. Hot air welding is mainly used for welding plastics such as polyvinyl chloride, polyolefins, polyoxymethylene, nylon, etc. It can also be used for welding plastics such as polystyrene, ABS, polycarbonate, chlorinated polyether, chlorinated polyethylene, etc. It is mainly composed of an air compressor, a pressure storage tank and an air filter. The function of the filter is to remove moisture, dust and grease from the air, which is beneficial to improve the strength of the weld and extend the service life of the welding gun. The compression capacity of the air compressor is generally 2-6m3 / h, and 12 for fast welding guns. m3 / h. The gas used varies with the type of plastic. For general plastics, air can be used. For easily oxidized plastics, such as polyethylene, polypropylene, etc., it is best to use inert gases such as nitrogen or carbon dioxide. Welding guns can be mainly divided into three types: gas welding guns, electric welding guns and fast welding guns. Gas welding guns use the combustion of combustible gas to heat the compressed air. Electric welding guns use electric heating wires to heat the compressed air. Fast welding guns are improved electric welding guns that increase the amount of air. The working efficiency of electric welding guns is not as good as that of gas welding guns, but there is no fire and explosion and danger, and the safety factor is higher than that of gas welding guns. Fast welding guns are generally not used for welds with a thickness of less than 2mm.

[0003] However, it still has some disadvantages. For example, in the welding of airship bladder, different positions need to use welding heads of different calibers. Usually, the connection method between the welding head and the air outlet pipe is more complicated, and different welding machines are required for welding. The process of disassembling and replacing the welding head is more complicated, which will waste a lot of working time of the staff and reduce work efficiency.
