The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] See also Figure 1 and Figure 2 The utility model discloses a bra back buckle machine wing cloth pressing mechanism, which includes a support plate 100, a plurality of pressing blocks 200 and a plurality of elastic members 300.

[0032] One end of the support plate 100 is connected to the main body of the bra back fastener machine;

[0033] The plurality of pressing blocks 200 are distributed on the support plate 100 along the length direction of the support plate 100 . The plurality of pressing blocks 200 are disposed below the support plate 100 and can slide up and down relative to the support plate 100 .

[0034] The multiple elastic members 300 cooperate with the multiple pressing blocks 200 one by one. The elastic members 300 drive the pressing blocks 200 downward away from the support plate 100. The multiple pressing blocks 200 are used to fit different areas of the wing cloth to press the wing cloth down on the workbench of the bra back buckle machine.

[0035] The support plate 100 supports multiple pressing blocks 200 and multiple elastic members 300. One end of the support plate 100 is connected to the main body of the bra back buckle machine so that the support plate 100 and the multiple pressing blocks 200 are above the workbench of the bra back buckle machine. Under the action of the multiple elastic members 300, the multiple pressing blocks 200 move downward and maintain a downward pressed state, thereby pressing multiple areas of the wing cloth down on the workbench.

[0036] Since each pressing block 200 can move up and down and maintain a downward pressing state, multiple pressing blocks 200 can press down multiple areas of the wing cloth respectively. The downward movement degree of the pressing blocks 200 corresponding to the higher areas of the wing cloth is greater than the downward movement degree of the pressing blocks 200 corresponding to the lower areas of the wing cloth, so that all the pressing blocks 200 can stably press down multiple areas of the wing cloth on the workbench, so that the bra back buckle machine's wing cloth pressing mechanism can be suitable for different wing cloths, ensuring the stability of the downward pressing wing cloth, making it easier for the bra back buckle machine to sew the back buckles on the wing cloth, and improving work efficiency and sewing accuracy.

[0037] After the wing cloth is sewn with the back buckle, the support plate 100 is raised, which drives the multiple elastic members 300 and the multiple pressing blocks 200 upward, moving the multiple pressing blocks 200 away from the workbench, making it easier to remove the stitched wing cloth and back buckle from the workbench and place a new wing cloth and back buckle on the workbench. It is understood that the higher area of ​​the wing cloth can be a hem at the edge of the wing cloth or a decorative structure on the wing cloth.

[0038] See also Figure 1 and Figure 2 In some embodiments, the support plate 100 is connected to the pressing block 200 through a limiting member 400. The limiting member 400 limits the pressing block 200 on the support plate 100 to prevent the pressing block 200 from separating from the support plate 100, so that the support plate 100 can move with the pressing block 200. At the same time, the pressing block 200 can move closer to and away from the support plate 100 on the support plate 100.

[0039] See also Figure 2In some embodiments, the limiting member 400 includes a connecting portion 410 and a limiting portion 420 provided on the upper end of the connecting portion 410. The supporting plate 100 is provided with a limiting hole 110. The lower end of the connecting portion 410 is passed through the limiting hole 110 and is detachably connected to the pressing block 200. The limiting portion 420 abuts against the upper surface of the side wall of the limiting hole 110. The connecting portion 410 moves up and down in the limiting hole 110. The connecting portion 410 and the pressing block 200 move synchronously. When the connecting portion 410 and the pressing block 200 move downward, the limiting portion 420 abuts against the upper surface of the side wall of the limiting hole 110 to prevent the connecting portion 410 and the pressing block 200 from separating from the supporting plate 100.

[0040] It is understood that the connecting portion 410 and the limiting portion 420 are both cylindrical, the limiting hole 110 is a circular through hole, and the diameter of the limiting portion 420 is larger than the diameters of the connecting portion 410 and the limiting hole 110. The difference between the height of the connecting portion 410 protruding from the pressing block 200 and the height of the limiting hole 110 is the travel distance of the pressing block 200 in sliding up and down on the support plate 100.

[0041] In some embodiments, the lower end of the connecting portion 410 is threadedly connected to the pressing block 200, thereby achieving detachable installation of the connecting portion 410 and the pressing block 200. After the connecting portion 410 is passed through the limiting hole 110 from top to bottom, the lower end of the connecting portion 410 is threadedly connected to the pressing block 200, thereby completing the connection between the connecting portion 410 and the pressing block 200.

[0042] By relatively twisting the limiting member 400 and the pressing block 200 , the height of the connecting portion 410 protruding from the pressing block 200 can be adjusted, thereby adjusting the sliding stroke of the pressing block 200 .

[0043] See also Figure 3 In some embodiments, the limiting hole 110 is a stepped through hole that is larger at the top and smaller at the bottom, and the limiting portion 420 is passed through the upper end of the limiting hole 110, that is, the limiting portion 420 can be received in the upper end of the limiting hole 110 to prevent the limiting portion 420 from protruding from the support plate 100.

[0044] As needed, the depth of the upper end of the limiting hole 110 minus the height of the limiting portion 420 can be equal to the stroke of the pressing block 200 to ensure that when the limiting member 400 and the pressing block 200 move up to a high position on the support plate 100, the limiting portion 420 does not protrude from the support plate 100.

[0045] See also Figure 1 and Figure 2In some embodiments, the elastic member 300 is a spring, which is sleeved on the connecting portion 410, and the two ends of the elastic member 300 respectively abut against the support plate 100 and the pressing block 200. After the connecting portion 410 is passed through the limiting hole 110 from top to bottom, the elastic member 300 is sleeved on the connecting portion 410, so that one end of the elastic member 300 abuts against the support plate 100, the lower end of the connecting portion 410 is threadedly connected to the pressing block 200, and the other end of the elastic member 300 abuts against the pressing block 200. In this way, the limiting member 400, the elastic member 300, and the pressing block 200 are installed on the support plate 100.

[0046] See also Figure 1 and Figure 2 In some embodiments, a guide hole 120 is further provided on the support plate 100, and a guide column 500 is provided on the pressing block 200. The guide column 500 is passed through the guide hole 120. The cooperation between the guide column 500 and the guide hole 120 serves to guide the sliding direction of the pressing block 200.

[0047] It can be understood that the support plate 100 is plate-shaped, the support plate 100 is parallel to the horizontal plane, the length direction of the support plate 100 is horizontal, the axial direction of the guide hole 120, the axial direction of the guide column 500, the axial direction of the limiting hole 110, the axial direction of the limiting member 400 and the sliding direction of the pressure block 200 on the support plate 100 are all up and down directions.

[0048] See also Figure 2 In some embodiments, the lower surface of the pressing block 200 is provided with anti-slip grooves, which help the pressing block 200 to stably press the wing cloth on the workbench. The anti-slip grooves can be a wavy structure or a plurality of parallel or intersecting convex strips.

[0049] The lower surface of the support plate 100 is provided with a limiting groove in an area corresponding to the pressing block 200 , and the pressing block 200 can enter the limiting groove when moving upward.

[0050] See also Figure 1 and Figure 3 In some embodiments, a first connecting hole 130 is provided on one end of the support plate 100. The axial direction of the first connecting hole 130 is the up-down direction. The first connecting hole 130 is an oblong hole. The length direction of the first connecting hole 130 is perpendicular to the length direction and the up-down direction of the support plate 100. The support plate 100 is connected to the main body of the bra back buckle machine through a fastener passed through the first connecting hole 130.

[0051] When loosening the fasteners, the position of the support plate 100 can be adjusted along the length direction of the first connecting hole 130 so that as many pressing blocks 200 as possible are pressed on the wing cloth. When tightening the fasteners, the support plate 100 can be fixed to the main body of the bra back buckle machine.

[0052] An avoidance groove is provided on the lower surface of the support plate 100 in the area corresponding to the first connecting hole 130. When the support plate 100 is connected to the main body of the bra back buckle machine through the connecting plate, the connecting plate extends into the avoidance groove, so that the lower surface of the support plate 100 is as close to the workbench as possible. Even if the downward movement of the pressing block 200 is small, it can ensure that the pressing block 200 on the support plate 100 can press the wing cloth down onto the workbench.

[0053] It is understandable that the first connection hole 130 is a stepped hole with a larger top and a smaller bottom. The fastener can be a screw or a screw.

[0054] See also Figure 1 and Figure 3 In some embodiments, a second connecting hole 140 is provided on the other end of the support plate 100, and the second connecting hole 140 is used to connect to a presser foot, which can be the presser foot of the original bra back buckle machine or an additional presser foot.

[0055] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
