Embodiment 1

[0087] like figure 2 and Figure 14 As shown, the hot air welding machine of this embodiment includes a frame on which a pressurizing mechanism and a metal conduction hot-melting mechanism are arranged. The metal conductive hot-melt mechanism is suitable for hot-melting the laminated brushed cloth C and the upper and lower edge bands at the entrance of the pressurizing mechanism. The pressurizing mechanism is suitable for pressurizing, welding and transporting the hot-melted drawing cloth C and the upper and lower edging belts. The internal heat is conducted through the metal conduction hot-melt mechanism, and the hot-melt brushed cloth C and the upper and lower edge bands are then pressurized and welded by the pressurizing mechanism. Avoid hot air heat diffusion, not easy to cause material wrinkle deformation, no bright edges around welding, improve welding quality.

[0088] Specifically, such as Figure 4 As shown, the metal conduction hot-melt mechanism includes two bl...

Embodiment 2

[0105] like image 3 , Figure 8 and Figure 15 As shown, the present invention provides another alternative embodiment of the press mechanism.

[0106] The difference from Example 1 is:

[0107] The pressurizing mechanism is a two-wheel set different-axis pressurization mechanism, and the double-wheel set different-axis pressurization mechanism includes upper and lower belt pulleys which are set to rotate synchronously. The outer section of the brushed cloth and the lower edge belt C are pressure welded and conveyed. The double-wheel group cross-axis pressurizing mechanism also includes upper and lower material wheels which are set to rotate synchronously, and the upper and lower material wheels are suitable for pressurizing, welding and transporting the inner section of the brushed cloth passing through. The lower pulley 8 and the upper pulley 7 have a synchronous rotation speed V1, and the lower material wheel 10 and the upper material wheel 9 have a synchronous rotation ...

Embodiment 3

[0114] like Figures 2 to 15 As shown, on the basis of the first or second embodiment, the third embodiment provides a working method of the hot air welding machine, which is implemented by using the hot air welding machine of the first or second embodiment.

[0115] The rolled edging tape is unwound through the tape unwinding reel 25, and then guided and drawn by the guide column 28. The edging tape passes through the auxiliary guide block 23 and is guided into a V shape, and the V-shaped edging tape passes through the guide block 22 and is guided into a V shape. After the U shape, it is laminated with brushed cloth.

[0116] The air heated by the outside penetrates into the hot air cavity 3 from the air inlet end 4 of the blower heat wedge, and is discharged through the air outlet end 5, forming a thermal cycle. During the circulating operation of the hot air, the heat of the hot air is conducted to the welding part 1 of the blowing hot wedge, so that the welding part 1 hea...

Abstract

The invention belongs to the technical field of plastic pressing and hot melting, and particularly relates to a hot air welding machine and a working method and using method thereof. The hot air welding machine comprises a rack, and a pressurizing mechanism and a metal conduction hot melting mechanism are arranged on the rack; the metal conduction hot melting mechanism is suitable for carrying outhot melting on a wiredrawing cloth, an upper edge covering belt and a lower edge covering belt laminated at the inlet of the pressurizing mechanism; and the pressurizing mechanism is suitable for pressurizing, welding and conveying the hot-melted wiredrawing cloth, the upper edge covering belt and the lower edge covering belt. According to the hot air welding machine, heat needed by welding is obtained in a heat conduction mode, hot air penetrates through a hot air cavity and then is exhausted, the hot air does not need to make direct contact with the wiredrawing cloth, the upper edge covering belt and the lower edge covering belt, the heat output range is centralized, hot air diffusion is prevented, material wrinkling deformation and bright edges generated in the periphery of the weldingposition are avoided, and the welding quality is improved. The small-size hot air cavity conducts heat conduction welding, high-temperature heat can be continuously output, and the welding efficiencyis high.

Description

technical field [0001] The invention belongs to the technical field of hot-melt plastic embossing, and in particular relates to a hot-air welding machine and its working method and usage method. Background technique [0002] Hot air welding machine is widely used in PVC, TPU or PE and other materials for sewing and sealing equipment. The sealing is realized by hot air welding and pressurization of tapes of the same material. The product and the tape can move synchronously during pressurization. [0003] As a hot-melt welding machine, CN109070485A discloses an inflatable structure welding device. It includes: a main body; a connecting part, which is arranged on the above-mentioned main body; an edge part supply part, which is arranged on the above-mentioned main part, and is used to supply the edge parts; a hot air injection unit, which is arranged on the above-mentioned connecting part, is used to supply hot air is sprayed from the edge part; and the pressurizing part is pr...
