[0001] The invention relates to the field of welding technology, in particular to a hot welding spacer, a hot welding arm group, a gantry type hot welding machine and a hot welding method. Background Art

[0002] When welding the board body or the tip of a traditional brushed cloth surfboard, it is necessary to pre-weld the board body material edges to align them, which is called pre-fixing. During pre-fixing, the welding points are prone to loose welding and easy to desolder, and the edge welding is prone to wrinkles. Or excessive welding damages the board body material, causing air leakage in the later stage, and a high scrap rate. The obvious pre-fixing marks seriously affect the appearance of the product. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-4 As shown, the hot-melt spacer comprises a metal sheet 3, wherein the metal sheet 3 is fixedly arranged between the upper and lower wheels, and a clearance area is arranged on the outward side of the end of the metal sheet 3, and a bevel is arranged on the inward side.

[0021] The clearance area is a bending portion 1, and the bending portion 1 forms a horizontal U-shaped area with an opening facing the material body.

[0022] The edges 2 of the metal sheet 3 do not have a blade surface.

[0023] During the forward process, the metal sheet 3 will separate the upper and lower fabrics of the drawing cloth, that is, the metal sheet 3 is located in the middle of the upper and lower fabrics of the drawing cloth. When the upper and lower wheels press the material at the same time, the metal sheet 3 will block the material and will not interfere with the other layer of the material due to the speed difference of the material wheel. In this way, they can be operated separately. The U-shaped area of ​​the metal sheet 3 can be limited to prevent the material from being over-positioned. The bevel can prevent the wire from being caught during the movement. The edge 2 can be processed to prevent the edge 2 from being too sharp to scratch the wire.

[0024] The hot-melt arm group includes a metal sheet 3, which is fixed on a frame 5. The upper and lower rows of wheels on the metal sheet 3 are respectively connected to a power source. The movement of the upper and lower wheels in the outer row is controlled by a lifting assembly on the frame 5, and the movement of the upper and lower wheels in the inner row is controlled by a lifting assembly in the frame 5. The heating assembly is fixed on the lifting assembly that controls the movement of the upper and lower wheels in the outer row.

[0025] A lifting assembly for controlling the movement of an upper and lower wheel body in an outer row is provided with a distance displacement assembly and a swing assembly for controlling the distance and swing angle of the heating assembly.

[0026] The frame 5 is provided with a hemming material conveying assembly for forming the hemming material into a V-shape and hot-melting the hemming material with the drawing cloth through the heating part of the heating assembly.

[0027] When the welding arm group is in use, the hemming cloth will be fed in and melted before the material wheel presses the material. At this time, the material wheel presses down. During use, the heating component can adjust the distance between the heating component and the material wheel, as well as the swing angle of the heating component to achieve multi-directional adjustment.

[0028] The gantry-type hot-melt welding machine comprises a hot-melt welding arm group with a metal sheet body 3. The hot-melt welding arm group is provided with at least two groups, and both are provided on the gantry through a moving component. The bottom of the gantry is provided on a ground rail through a sliding component. A material placing table is provided between the ground rails on both sides. When the gantry moves, the hot-melt welding arm group operates the material body on the material placing table.

[0029] The hot-melt welding arm group is arranged on the gantry, and when the gantry moves, the hot-melt welding arm group can operate along the edge of the material body.

[0030] The hot-melt method comprises the following steps: step 1: stacking two groups of materials of different lengths; step 2: placing the upper and lower wheels of the inner row of the hot-melt arm group against the upper and lower stacked materials respectively, placing the metal sheet between the upper and lower materials, and separating the contact surfaces of the materials; step 3: the packaging material is wrapped around the upper and lower materials by conveying, and after hot-melting, the upper and lower wheels of the outer row of the hot-melt arm group are pressed and fused; step 4: the hot-melt arm group starts to move along the side walls of the upper and lower materials, and the upper and lower wheels of the outer row are pressed and moved at the same time. During the movement of the upper and lower wheels of the inner row, in order to align the side walls of the upper and lower materials, the speed is adjusted when they are against the metal sheet.
