[0036] Seamless underwear is beautiful and comfortable and is favored by women. In pursuit of comfort, seamless underwear often uses hemming technology during production. The hemming jigs used in traditional hemming technology are mostly flat closed structures, and the part used for molding in traditional hemming jigs is longer, and the contact area with the patch is large. Since the surface of the patch is coated with a layer of glue, the patch is easily stuck to the surface of the jig, which makes the friction resistance of the patch during the hemming process large, affecting the hemming quality and efficiency.

[0037] Aiming at the defects of the prior art, the utility model provides an underwear edge binding fixture, Figure 1-5 As shown, the hemming jig includes a mounting base and a jig body, and the jig body is fixed to a designated position on the hemming equipment by means of the mounting base.

[0038] The fixture body includes a carrier plate 1, a guide assembly 2 mounted on the carrier plate 1, and a molding component 3 fixed to the discharge end of the carrier plate 1. In this embodiment, the feed end of the carrier plate 1 is located on the right side of the carrier plate 1, and the discharge end is located on the left side of the carrier plate 1.

[0039] The front side of the carrier plate 1 is provided with a guide groove 11 for accommodating the patch 100 . The guide assembly 2 is fixed in the guide groove 11 and arranged parallel to the carrier plate 1 to confine the patch 100 between the guide groove 11 and the guide assembly 2 .

[0040] The molding component 3 is a semi-conical shell, the bottom of which is connected to the outlet end of the guide groove 11, the cone surface is located at the front side of the carrier plate 1, and the section opening of the semi-conical shell is located at the rear side of the carrier plate 1. The molding component 3 contains a molding channel 31 for the patch 100 to be folded and formed. The patch in the guide groove 100 enters the molding channel 31 from the opening of the bottom of the cone, passes through the portion of the section opening corresponding to the tip of the cone, and is folded and formed.

[0041] The conical tip of the forming member 3 is provided with a U-shaped through groove 32 for the fabric 200 to be hemmed to pass through. The U-shaped through groove 32 penetrates the forming member 3 from the front to the back along the carrier plate 1 and communicates with the forming channel 31. The forming channel 31 is divided into a first limiting groove 311 and a second limiting groove 312 arranged in the upper and lower parts at the U-shaped through groove 32. Figure 3 When entering the forming channel 31 in the direction of the middle arrow A, the upper edge and the lower edge of the patch material 100 are located in the first limiting groove 311 and the second limiting groove 312 respectively, and the patch material 100 moves from the bottom of the cone to the tip of the cone, and gradually folds in half under the restriction of the semi-conical structure. Figure 3 The direction of the middle arrow B passes through the U-shaped slot 32 into the folded patch 100, and the two pass through the hot pressing device together to make the patch 100 fit and fix to the upper and lower surfaces of the edge of the fabric 200 to be hemmed, completing the hemming operation.

[0042] In one embodiment, the guide groove 11 is extended along the length direction of the carrier plate 1 , extending from the feed end of the carrier plate 1 to the discharge end of the carrier plate 1 .

[0043] In a specific embodiment, Figure 2 As shown, a slot plate 33 is disposed in the U-shaped slot 32, and the slot plate 33 is arranged in a shape corresponding to the U-shaped slot 32, and is used to form a channel for the fabric 200 to be hemmed to pass through. The slot plate 33 is fixed in the forming channel 31, and the part of the forming channel 31 corresponding to the U-shaped slot 32 is divided into a first limiting slot 311 and a second limiting slot 312 arranged up and down. The patch 100 is folded in half through the first limiting slot 311 and the second limiting slot 312 to form, and the slot plate 33 provides a channel for the fabric 200 to be hemmed to enter between the folded patches, so that the patch 100 is folded in half and located at the upper and lower sides of the fabric 200 to be hemmed, and after passing through the hot pressing device, the patch 100 is attached to the edge of the fabric 200 to be hemmed, and the hemming operation is completed.

[0044] In one embodiment, Figure 1 As shown, the guide assembly 2 includes a pressure rod 21 and a pressure sheet 22 disposed on the pressure rod 21. The two ends of the pressure rod 21 are respectively fixed to the upper and lower groove walls of the guide groove 11, and the patch 100 is restricted between the pressure rod 21 and the guide groove 22 by the pressure rod 21. A connecting ring 220 is disposed at one end of the pressure sheet 22, and the pressure sheet 22 is sleeved on the pressure rod 21 through the connecting ring 220. The pressure sheet 22 contacts the patch 100 and is used to cooperate with the pressure rod 21 to restrict the patch in the guide groove 11, ensuring that the patch 100 always remains flat during the process of moving along the guide groove 11. Furthermore, the pressure sheet 22 is an arc-shaped structure, with one end away from the pressure rod 21 tilted up, and one end close to the pressure rod 21 in contact with the patch 100, providing guidance for the patch 100.

[0045] In a specific embodiment, three pressing plates 22 are arranged on the pressing rod 21, and the three pressing plates 22 are evenly distributed on the pressing rod 21. The three pressing plates 22 are used to press the patch 100 flat in the guide groove 11 instead of using a whole large pressing plate in order to reduce the contact area with the patch, thereby reducing the friction force of the patch 100 during the movement, avoiding adhesion with the guide assembly 2, and ensuring the hemming quality and hemming efficiency.

[0046] Furthermore, the width of the pressing sheet 22 is 3 mm, which can ensure that the patch 100 is effectively restricted and that the contact area between the pressing sheet 22 and the patch 100 is not too large to cause adhesion.

[0047] In one embodiment, the fixture body includes two sets of guide components 2, which are respectively arranged near the feeding end and the discharging end of the carrier plate 1, so that the patch 100 can be located flatly in the guide groove 11. Excessive increase of guide components will not only increase the manufacturing cost, but also increase the friction between the guide components 2 and the patch 100. The two sets of guide components 2 are arranged in sequence along the advancing direction of the patch 100, and the center lines of the pressure rods 21 of the two sets of guide components 2 are in the same plane, and the plane is parallel to the plane where the carrier plate 1 is located, so as to avoid affecting the limiting effect on the patch 100.

[0048] If the upper and lower layers of the patch 100 are staggered after being folded in half, the quality of the hemming and the appearance of the patch 100 will be affected. Figure 1 As shown, the molding component 3 is provided with a first limiting piece 34 and a second limiting piece 35. The first limiting piece 34 is wrapped around the side of the first limiting groove 311 facing the U-shaped through groove 32, and the second limiting piece 35 is wrapped around the side of the second limiting groove 312 facing the U-shaped through groove 32, which are used to limit the patch 100 in the molding channel to prevent the patch 100 from passing through the front side of the molding component 3, thereby ensuring the stable operation of the hemming operation. The first limiting piece 34 and the second limiting piece 35 are made of stainless steel material with Teflon sprayed on the surface. Since the first limiting piece 34 and the second limiting piece 35 are the parts that directly contact the rubber surface of the patch 100, Teflon coated plates with good lubricity are selected for production. Compared with ordinary stainless steel plates, under the same conditions, the surface friction coefficient of Teflon coated stainless steel plates is only one-fourth of that of ordinary stainless steel plates.

[0049] In one embodiment, the guide groove is used to prevent the patch 100 from shifting in the up and down directions during the forward movement, thereby ensuring the quality of the hemming. Specifically, the length of the guide groove 11 is 6 cm. The length of the guide groove 11 should not be too long. Too long will result in poor guiding effect, causing the patch 100 to shift, resulting in different hemming areas on the front and back of the fabric, thereby reducing the rework rate. Compared with traditional hemming jigs, the overall length of the jig body is 10 mm, which is about one-fifth of the length of traditional hemming jigs. The length of the jig body is shortened, thereby reducing the friction between the patch and the jig body. Its hemming quality and efficiency are better than traditional hemming jigs.

[0050] In a specific embodiment, Figure 4 As shown, the mounting base includes a bottom plate 4 and a vertical plate 5 which are vertically arranged to each other, and the bottom edge of the vertical plate 5 is slidably connected to the bottom plate 4. The jig body is mounted on the vertical plate 5, and the bottom plate 4 is fixed to the hemming equipment. The relative position between the vertical plate 5 and the bottom plate 4 is adjusted, thereby adjusting the installation position of the jig body on the hemming equipment.

[0051] The vertical plate 5 is provided with a first mounting hole 51, and the fixture body is mounted on the vertical plate 5 through the first mounting hole 51. Specifically, a mounting plate 6 is welded and fixed to the back side of the fixture body, and a threaded hole 61 is provided on the mounting plate 6. The first mounting hole 51 and the threaded hole 61 are connected by bolts to fix the fixture body to the vertical plate 5.

[0052] The bottom plate 4 is provided with a second mounting hole 41 , and the second mounting hole 41 is used for mounting the hemming jig on the hemming equipment.

[0053] Another embodiment of the utility model provides an edge binding device, including a heat pressing device and the underwear edge binding jig provided in the above embodiment. The heat pressing device is connected to the rear side of the underwear edge binding jig, and after the edge binding fabric and the patch are aligned, they enter the heat pressing device together for bonding and fixing to complete the edge binding operation.

[0054] The underwear hemming jig and hemming equipment provided by the embodiment of the utility model guide the patch smoothly and steadily into the forming component through the cooperation of the guide assembly and the guide groove so that the patch is folded in half to form. The guide assembly reduces the contact area between the patch and the jig body, thereby reducing the friction force encountered by the patch during its movement, reducing the probability of defective products due to adhesion between the patch and the jig body during the hemming process, reducing production rework, and reducing the rework rate by 2%, thereby improving the hemming quality and production efficiency. Compared with the traditional hemming jig, the overall length of the jig body is 10mm, which is about one-fifth of the length of the traditional hemming jig, shortening the length of the jig body, thereby reducing the friction between the patch and the jig body, making its hemming quality and hemming efficiency better than the traditional hemming jig.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
