Embodiment Construction
[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0012] In the accompanying drawings of this embodiment, only a schematic diagram of the relevant part of the present invention is shown. In practice, the closed hot air generator 1 also needs to be connected with an air pump structure that can continuously input air and an exhaust structure that can discharge high-temperature air to heat the workpiece. , the exhaust structure and the air pump structure can adopt mature prior art, and this embodiment will not describe in detail.
[0013] The implementation of the present invention will be described in detail below in conjunction with specific drawin...

The invention relates to the technical field of plastic welding, and discloses a closed hot air generator and plastic welding equipment, wherein the closed hot air generator includes a heating inner cylinder for heating air and an insulating outer cylinder wrapped outside the heating inner cylinder, the heating inner cylinder There is a heat pipe inside the cylinder, one end of the insulation outer cylinder is provided with an input end for air inflow, and the other end is provided with an output end for air flow out, and there is a gap between the heating inner cylinder and the insulation outer cylinder for air to flow through. In the heated gap, there is an air guide structure for increasing the air stroke in the gap, and the air guide structure includes a plurality of air guide walls arranged in the gap, and an air guide cavity for air to flow through is formed between the air guide walls. The closed hot air generator in the present invention adopts double-layer sleeves to heat the air in the gap between the heating inner cylinder and the heat preservation outer cylinder, and uses hot air as the heating medium to preheat the workpiece as a whole to achieve The welding fusion effect is good, the purpose of leaving no weld seam, and the final welding result is firm.
Description
technical field [0001] The invention relates to the technical field of plastic welding, in particular to a closed hot air generator and plastic welding equipment. Background technique [0002] In the heat treatment process of thermoplastic welding of workpieces such as plastic parts, it is necessary to heat the workpiece to soften it and then weld it. In the prior art, aluminum or copper is generally used as the heat conduction medium, which is heated by a heating pipe, and the heated heat conduction medium directly contacts the workpiece to soften or melt, and then welding is performed. [0003] In this heating method, parts of the workpiece are directly melted at high temperature in a short period of time, and there is no preheating and softening process as a whole. After welding, only the melted part is attached to the surface of another workpiece. There is a gap between the welds, and the two workpieces cannot be integrated. . The two workpieces welded by this welding ...
