[0001] The utility model relates to the field of clothing processing equipment, in particular to a circumferential three-dimensional round edge overlock component. Background Art
[0002] With the development of society and the continuous improvement of people's living standards, clothing is generally hemmed in order to reduce the friction of the edges of components on the wearer when worn, prevent the edges from loosening, and improve comfort. At present, straight and arc hemming can basically be achieved using automatic equipment, but the circumferential three-dimensional structure with a convex part, such as a bra cup pad, requires manual operation for hemming, because this structure cannot be pressed down. After pressing, its edge is prone to warping, affecting the hemming seams. In addition, after pressing, bra cup pads of different shapes will also have various deformations in different positions, and the edge position cannot be guaranteed to be flattened. In this state, the hemming has a very high defect rate and is also prone to damage to the material. In view of this, a hemming component for the circumferential three-dimensional round edge structure is designed to ensure that the material to be processed is kept flat during the hemming process. The hemming component with a low defect rate has become an urgent problem to be solved. Utility Model Content

[0022] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.
[0023] like Figure 1 As shown, the utility model relates to a circumferential three-dimensional round edge seaming assembly, which includes a matching module 1, a pressing piece 2 and a driving module 4 capable of driving the matching module 1 to move, the matching module 1 has a pressing surface facing the material, the pressing piece 2 is fixedly connected to the matching module 1, and the pressing piece 2 protrudes from the pressing surface of the matching module 1, and a pressing convex portion protruding from the surface and in contact with the material is formed on the pressing surface, the contact surface between the pressing piece 2 and the material is a plane, and a buffer structure is provided on the contact surface. The device of the utility model is used for sewing edges at circumferential three-dimensional circular edge positions. Specifically, for example, for cup pads used in bras, when in use, the matching module 1 uses a shape that is compatible with the shape of the cup pad material. For example, for round cup pads, a round or polygonal matching module 1 is used (that is, the adaptation described in the utility model patent refers to the adaptation of the edge of the matching module 1 to the edge shape of the material to be hemmed. For example, for round cup pad materials, a square matching module 1 is used, and the pressing pieces 2 installed on the four edges of the matching module 1 can be pressed on the material near the edge, which is adaptation). The use of the adapted shape ensures that the material can be pressed as much as possible during sewing to prevent the edge from warping and affecting the hemming effect. The matching module 1 uses the pressing piece 2 to press the material at the edge to be hemmed, and uses a convex shape on the matching module 1. The pressing piece 2 on the surface of the module 1 can, when in use, allow the surface of the matching module 1 to contact the material, leaving a holding position for the convex part of the material, while the edge position is pressed by the pressing piece 2, and then the matching module 1 is driven by the driving module 4 to press the material and move the edge of the material to the working position of the hemming sewing machine, and then the driving module 4 drives the matching module 1 to rotate to adapt to the arc-shaped round edge of the material, thereby realizing the circumferential three-dimensional round edge hemming work and ensuring that the material will not warp and affect the hemming sewing problem during the working process. Since the pressing piece 2 uses a hard material to ensure that no deformation occurs during pressing, in order to avoid damage to the material by the pressing piece 2, a buffer structure is provided on the contact surface to increase the protection of the material to be processed and reduce the probability of defective products during processing.
[0024] like Figures 2 to 5As shown, the matching module 1 is a gasket with thickness, and a positioning and mounting portion 11 for mounting the press piece 2 is provided on the gasket, and the positioning and mounting portion 11 is arranged along the edge of the matching module 1. In order to ensure the stability of the structure when under pressure, the matching module 1 uses a gasket with thickness to avoid deformation when under pressure, which causes unstable pressing or displacement problems. When the press piece 2 is installed at the edge position, the edge position of the matching module 1 can be as close to the edge as possible when pressing the material, but can keep a distance from the edge to avoid hindering the hemming sewing work, and at the same time, the position that is not pressed is too close to the protruding position, causing the edge to be lifted and unable to sew the edge; in order to ensure the above effect, the matching module 1 can preferably use a module with an area smaller than the projected area of the material to ensure that the edge position does not protrude from the edge position of the material.
[0025] like Figure 2 As shown in the figure, as one of the embodiments, the pressing piece 2 is a strip structure arranged along the edge of the matching module 1, and a continuous protruding strip is formed along the edge of the pressing surface of the matching module 1. The pressing piece 2 installed in the matching module 1 uses a protruding strip arranged throughout the length, which is suitable for the edging of non-circular materials, such as half-cup coasters, arc-edge triangular coasters, etc. This continuous protruding strip can press this edge to prevent the non-standard shape of the workpiece from warping.
[0026] like Figure 3 , 4 As shown, in another embodiment, the pressing piece 2 is a columnar structure, and there are multiple of them. One end of the columnar structure is fixedly connected to the matching module 1, and there is a gap between adjacent pressing pieces 2. The other end protrudes from the pressing surface of the matching module 1. Multiple pressing pieces 2 together form a claw-shaped pressing structure. When in use, the multi-point pressing method composed of multiple pressing pieces 2 is suitable for standard-shaped workpieces to be processed, such as round bra coasters or oval bra coasters, etc. The use of a claw-shaped pressing structure can reduce the edge pressure area of the workpiece to be processed, and avoid edge warping due to a large pressure area at the edge.
[0027] like Figure 5 As shown, for materials with one end larger than the other such as "rabbit ear cup" and "petal cup", you can use Figure 5 The corresponding shape matching module 1 shown is used in conjunction with the strip-shaped pressing piece 2. The shapes are matched during use to ensure that the edge position can be pressed down, and for the large end side, it is ensured that no warping problem occurs during the hemming sewing process; the position of the mounting portion 11 on the matching module 1 can be the front side, the back side, or the side, to ensure that the pressing piece 2 is at the edge position of the matching module 1.
[0028] The contact surfaces of the plurality of pressing members 2 and one end of the material are located in the same plane, ensuring that the points of each pressing position are in the same plane, and ensuring that there will be no problem of uneven force on the pressure points and warping.
[0029] Auxiliary bristles 3 are arranged on the contact surface between the pressing piece 2 and the material. The auxiliary bristles 3 are elastic brushes, and the root of the brush is connected to the pressing piece 2, and the tip of the brush is directed outward from the center of the matching module 1 to the edge, forming an inverted buffer structure. A prostrate brush is arranged on the contact surface. When in use, it can not only act as a buffer between the rigid pressing piece and the soft material through the elasticity of the brush itself, but also when the prostrate bristles come into contact with the fabric fibers on the material, the tips will penetrate into the gap where the warp and weft threads of the fabric intersect for a short distance and then be fixed in position, so that the tip position is relatively fixed with the edge of the material to be processed. After the pressing piece continues to press down, the angle between the prostrate bristles and the contact surface will become smaller due to the pressure, or even stick to the surface. In this process, the tips of the bristles will push the edge of the material to be processed in an outward expansion direction for a short distance, so that the edge of the material to be processed can be in a flatter state for subsequent hemming and sewing operations, and the insertion position of the tip of the brush can be closer to the round edge of the material to be processed, and the elastic recovery of the bristles provides the bristles with force to press the edge of the material, so that it ensures a flat and fit state, and the bristles can be pulled out from the stitching position after the material is hemmed, which will not affect the processing effect. By arranging the bristles, the stability of the hemming effect when the component is used can be improved, and the yield rate can be improved.
[0030] The auxiliary bristles 3 have a sparse part 31 and a dense part 32, and the dense part 32 and the sparse part 31 are arranged in sequence from the root to the tip of the auxiliary bristles 3, forming a buffer structure from hard to soft in the outward expansion direction. By setting the dense part 32 and the sparse part 31, the dense part 32 located at the root position after pressing down during use can enhance the buffering effect between the rigid structure pressing piece and the material, and increase the protection effect. The sparse part 31 reduces the impact on the hemming sewing position through the larger spacing of the bristles or the more coefficient of the bristle tip, and can be easily pulled out, further enhancing the impact on the material to be processed during the use of the device and improving the neatness of the hemming effect of the finished product;
[0031] Specifically, the dense part 32 and the sparse part 31 can be formed in the following manner, such as: using two types of long and short bristles, the long bristles are arranged in sequence at intervals, so that the layer where the short bristles are located has both short bristles and the lower part of the long bristles, together forming a dense part, and the upper part has only the slight part of the long bristles, forming a sparse part;
[0032] You can also use bristles that are thick at the bottom and thin at the top. The thick bristles at the bottom take up more space, forming a dense part, while the upper bristles become thinner and the distance between the bristles is larger, forming a sparse part.
[0033] Alternatively, the lower part may be a yarn mesh structure formed by weaving warp and weft, and the lower part may have only a single warp / weft strip, forming a structure in which the lower part is dense and the upper part is sparse.
[0034] The angle between the auxiliary bristles 3 and the material contact surface of the pressing piece 2 is 5-10°. Within this angle range, the auxiliary bristles can provide effective buffering performance and also ensure the tip to push the edge of the material to be processed.
[0035] The driving module 4 includes a telescopic driving module 41, a rotating driving module 42 and a connecting member 43. The rotating end of the rotating driving module 42 is connected to the fixed end of the telescopic driving module 41. The moving end of the telescopic driving module 41 is connected to the matching module 1 through the connecting member 43, forming a motion mechanism that can drive the matching module 1 to do lifting and rotation. When in use, the driving module 4 acts as a mechanical arm. The telescopic driving module 41 can make the material pressing piece 2 on the matching module 1 press the material or lift and release the material. The rotating driving module 42 can rotate the matching module 1 at the hemming sewing position to achieve the hemming sewing effect of the hemming sewing machine with a fixed position. Specifically, the connecting member 43 can use a detachable screw nut for locking and fixing. In addition, the device also includes a workbench and an hemming sewing machine. The hemming sewing machine and the driving module 4 are both installed on the workbench. The material to be processed is pressed on the smooth workbench surface, which can ensure that after being pressed, the material to be processed can still move or rotate, and will not run out of position, so as to jointly achieve a complete hemming processing function.

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 embodiments here.
