[0033] The preferred embodiments of the present invention will be further described with reference to the accompanying drawings. Figure 4 As shown, an automatic underwear forming device includes a folding mechanism 100 and a laminating mechanism 200. A conveying mechanism 300 is arranged at the bottom of the folding mechanism 100. The folding mechanism 100 includes a workbench 110. The workbench 110 is used to place a sheet 10 to be processed. Figure 1 As shown, the sheet 10 includes a substrate portion 11, a first bending portion 12 is provided on the substrate portion 11, a second bending portion 13 is provided at one end of the substrate portion 11, and the first bending portion 12 and the second bending portion 13 are connected by a connecting portion 14, as shown in FIG. Figure 3 As shown, the folding mechanism 100 is used to keep the first bending portion 12 and the second bending portion 13 stacked on top of the substrate portion 11, and the conveying mechanism 300 is used to convey the workbench 110 to the bottom of the bonding mechanism 200, and the bonding mechanism 200 is used to heat and bond the first bending portion 12 and the second bending portion 13 together.

[0034] In the working state of this embodiment, if Figure 1 As shown, the sheet 10 to be processed is first placed on the workbench 110, and then the folding mechanism 100 is started. Figure 2 As shown, the folding mechanism 100 first bends the first bending portion 12 relative to the substrate portion 11, and then Figure 3 As shown, the second bending portion 13 is bent relative to the base material portion 11 so that the second bending portion 13 is located above the base material portion 11, and at the same time, the first bending portion 12 and the second bending portion 13 are kept stacked together above the base material portion 11. Next, the conveying mechanism 300 is started to convey the workbench 110 to the bottom of the fitting mechanism 200. During this process, the folding structure always keeps the first bending portion 12 and the second bending portion 13 stacked above the base material portion 11. Finally, the fitting mechanism 200 is started to heat and fit the stacked first bending portion 12 and the second bending portion 13 to form underwear.

[0035] Compared with the prior art, the present application utilizes a folding mechanism 100, a fitting mechanism 200 and a conveying mechanism 300, so that the sheet 10 can be directly formed into the shape of underwear after automatic folding and heating. The molding quality is high and the speed is fast. The entire process does not require human intervention and is completed automatically, which greatly improves the efficiency of underwear production and saves production costs.

[0036] On the basis of the above embodiments, Figure 5 As shown, a supporting arm 120 is disposed above the workbench 110, and the supporting arm 120 is located between the substrate portion 11 and the first bending portion 12. First bending devices 130 are disposed on both sides of the workbench 110. Figure 2 As shown, the first bending device 130 is used to bend the first bending portion 12 relative to the substrate portion 11, and a second bending device 140 is provided on one side of the bottom edge of the workbench 110. Figure 3 As shown, the second bending device 140 is used to bend the second bending portion 13 relative to the substrate portion 11 so that the second bending portion 13 is located above the substrate portion 11, while keeping the first bending portion 12 and the second bending portion 13 stacked together above the substrate portion 11.

[0037] On the basis of the above embodiments, Figure 6 As shown, the first bending device 130 includes a first movable plate 131. When the sheet 10 is placed on the workbench 110, the first movable plate 131 is located below the first bending portion 12. The first movable plate 131 is axially connected to both sides of the workbench 110. A first propulsion cylinder 132 is arranged obliquely below the outer side of the first movable plate 131. The driving end of the first propulsion cylinder 132 is connected to the outer side of the first movable plate 131. When the first propulsion cylinder 132 is started, the first propulsion cylinder 132 bends the first movable plate 131 toward the inner side of the workbench 110, so that the first bending portion 12 is bent relative to the substrate.

[0038] In some embodiments, Figure 6 As shown, a second movable plate 133 is arranged on the outer side of the first movable plate 131. When the sheet 10 is placed on the workbench 110, the second movable plate 133 is located below the first bending portion 12. The second movable plate 133 is axially connected to both sides of the first movable plate 131. When the first thrust cylinder 132 bends the first movable plate 131 toward the inner side of the workbench 110, the second movable plate 133 can perform a second bend on the first bending portion 12 so that the outer side of the first bending portion 12 can be placed on the supporting arm 120, which makes it easier to keep the first bending portion 12 and the second bending portion 13 stacked on top of the substrate portion 11.

[0039] On the basis of the above embodiments, Figure 6 As shown, the second bending device 140 includes a third movable plate 141, and the third movable plate 141 is connected to the workbench 110 through a hinge 142, so that the two are axially connected. When the sheet 10 is placed on the workbench 110, the third movable plate 141 is located below the second bending portion 13, and the connecting portion 14 is located above the hinge 142. A second propulsion cylinder 143 is provided at the bottom of the workbench 110, and a first connecting plate 144 is provided at the bottom of the third movable plate 141. The first connecting plate 144 is connected to the driving end of the second propulsion cylinder 143. When the second propulsion cylinder 143 is started, the second propulsion cylinder 143 can bend the third movable plate 141 toward the inner side of the workbench 110 with the hinge 142 as the axis, so that the second bending portion 13 is bent relative to the substrate.

[0040] In some embodiments, when the second thrust cylinder 143 bends the third movable plate 141 with the hinge 142 as the axial inner side of the workbench 110, the third movable plate 141 comes into contact with the supporting arm 120, thereby making the first bending portion 12 and the second bending portion 13 come into contact on the supporting arm 120, thereby keeping the first bending portion 12 and the second bending portion 13 stacked above the substrate portion 11.

[0041] In some embodiments, Figure 7 As shown, a first support plate 134 is provided at the bottom of the first bending device 130, the first movable plate 131 and the first propulsion cylinder 132 are installed on the first support plate 134, a first rotating motor 135 is provided at the bottom of the first supporting plate 134, a screw rod 136 is connected to the first rotating motor 135, a connecting seat 137 is sleeved on the screw rod 136, a first guide rail 138 is provided on one side of the connecting seat 137, a first sliding seat 139 is provided on the first guide rail 138, and the first sliding seat 139 is provided on the first sliding seat 139. 39 is connected to the connecting seat 137, and the first support plate 134 is installed on the first sliding seat 139. When the first rotating motor 135 is started, it drives the screw rod 136 to rotate, thereby driving the connecting seat 137 to move along the screw rod 136, and at the same time drives the first sliding seat 139 to move along the first guide rail 138, thereby driving the first support plate 134 to move relative to the workbench 110, so that the distance between the first bending device 130 and the workbench 110 can be adjusted, so that it can adapt to the placement of sheets 10 of various sizes.

[0042] On the basis of the above embodiments, Figure 8As shown, the bonding mechanism 200 includes a first bracket 210, a second support plate 220 is installed on the top of the first bracket 210, and two lifting cylinders 230 are installed on the second support plate 220. When the workbench 110 is located below the bonding mechanism 200, the lifting cylinder 230 is located directly above the supporting arm 120, and a second connecting plate 240 is arranged at the bottom of the lifting cylinder 230, and a heating plate 250 is arranged at the bottom of the connecting plate, and a spring 260 is arranged between the heating plate 250 and the second connecting plate 240. When the folding mechanism 100 completes its work, the workbench 110 is moved to the bottom of the bonding mechanism 200 through the conveying mechanism 300, and then the lifting cylinder 230 is started to drive the second connecting plate 240 and the heating plate 250 to descend at the same time until the heating plate 250 contacts the supporting arm 120. Since the first bending portion 12 and the second bending portion 13 form contact on the supporting arm 120, and the sheet 10 involved in the present application also has thermoplastic yarns, the heating plate 250 can heat the first bending portion 12 and the second bending portion 13 and then bond the first bending portion 12 and the second bending portion 13 together to form the shape of underwear. The function of the spring 260 is to reduce the impact of the heating plate 250 on the supporting arm 120.

[0043] On the basis of the above embodiments, Fig. 9 The conveying mechanism 300 includes two parallel second guide rails 310 arranged at the bottom of the folding mechanism 100, a second sliding seat 320 is arranged on the second guide rails 310, the folding mechanism 100 is installed on the second sliding seat 320, a third propulsion cylinder 330 is arranged between the second guide rails 310, and the driving end of the third propulsion cylinder 330 is connected to the folding mechanism 100. When the folding mechanism 100 needs to be moved to the bottom of the laminating mechanism 200, the third propulsion cylinder 330 is started to pull the folding mechanism 100 to move along the second guide rails 310.
