[0002] The vertical button is also called mushroom, which is divided into medium-long handle vertical button and short handle vertical button with buttonhole close to the button cover, including a button cap and a button handle with a stitching hole. In order to realize efficient automatic buttoning of the vertical button, a vertical button sewing machine is currently used to achieve it. When sewing the button, the vertical button sewing machine fixes the button cap of the vertical button vertically on the needle plate through the clamping arm, and the button handle is attached to the fabric for buttoning. A thread cutter is provided on the lower side of the needle plate. After the button is sewn, the thread cutter cuts the stitching. The vertical button is a common button sewn on clothes, but the existing clamping plate will occupy a part of the buckle foot of the vertical button, resulting in the device being unsuitable for the vertical button with a shorter buckle foot.

[0003] The prior art CN202321519768.0 discloses a tooling vertical buckle clamp, which includes a mounting seat, a positioning seat and a clamping mechanism, the positioning seat is provided with a processing notch, a first locking hole and a second locking hole, the clamping mechanism includes a clamping hand and a positioning member, the clamping hand and the positioning member form a clamping space for fixing the buckle cover, the positioning member has a positioning space for positioning the buckle piece, the clamping space and the positioning space are connected, the positioning seat is detachably connected to the mounting seat, and the clamping hand and the positioning member are both detachably connected to the positioning seat. Although the utility model can be adjusted according to the model of the vertical buckle to be applicable to the clamping of most common vertical buckles, the following problems still exist:

[0004] 1. When the device processes a vertical buckle with a shorter buckle foot, the clamping plate still occupies a part of the buckle foot, which not only limits its scope of application, but also may cause the buckle foot to deform or be damaged during the buckle sewing process, thereby reducing the yield rate.

[0005] 2. During use, the adaptability of the device to vertical buckles of different sizes and shapes still needs to be improved. Although the positioning seat and the clamping mechanism can be disassembled and connected, in actual operation, the process of replacing different components to adapt to different vertical buckles is rather cumbersome, which affects production efficiency.

[0006] 3. Existing clamping devices all apply pressure to the end face of the buckle cap of the standing buckle to fix it. Different buckle caps have different thicknesses. If the clamping force is insufficient, the standing buckle may be displaced during the buckling process, affecting the buckling effect. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a vertical button clamping device and a sewing machine using the device, which realizes the clamping and release of the circumferential surface of the button cap through the coordinated action of the upper clamping plate, the elastic clip, the lifting member and the limiting member, thereby avoiding the problem of the clamping plate occupying the button foot in the traditional device.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0010] One end of the upper clamping plate is horizontally arranged on the mounting seat through a rotating shaft and can rotate around the rotating shaft. One end of the elastic clip is fixed to the lower surface of the upper clamping plate, and the other end can be clamped by the circumferential surface of the buckle cap of the matching opposite buckle with the upper clamping plate. The upper clamping plate is provided with a limiting through hole for a limiting member to pass through and a lifting member that can rotate the upper clamping plate. The limiting member abuts on the elastic clip after passing through the limiting through hole. The lifting member can change the distance between the upper clamping plate and the elastic clip by cooperating with the limiting member.

[0011] It should be noted that the core of the present invention lies in the coordinated use of the upper clamping plate, the elastic clip, the lifting member and the limiting member. The upper clamping plate is connected to the mounting seat through a rotating shaft at one end so that it can rotate around the rotating shaft. One end of the elastic clip is fixed to the lower surface of the upper clamping plate, and the other end cooperates with the upper clamping plate to clamp the circumferential surface of the buckle cap of the standing buckle through elastic deformation. When the upper clamping plate rotates, one end of the lower clamping claw of the elastic clip is kept in position unchanged under the action of the limiting member, thereby ensuring the position stability of the standing buckle in the clamping state, so that the buttonhole can be accurately aligned with the needle hole of the sewing needle; and the lifting member can lift the upper clamping plate, thereby opening the distance between the upper clamping plate and the elastic clip, which is convenient for putting in or taking out the standing buckle. The elastic clip can enable the upper clamping plate to be reset under the elastic force of the elastic clip after being lifted and rotated, thereby clamping it on the circumferential surface of the buckle cap of the standing buckle.

[0012] Preferably, the upper clamping plate includes an upper pressing plate and an upper clamping claw, one end of the upper pressing plate is connected to the mounting seat via a rotating shaft, the upper clamping claw is detachably connected to the other end of the upper pressing plate, and the limiting through hole is arranged on the upper pressing plate.

[0013] It should be noted that the detachable design of the upper clamp can replace the appropriate upper clamp according to the different sizes or shapes of the buckles, which greatly improves the adaptability of the device, especially for those buckles with different sizes or thicknesses of buckle caps, which can be clamped more accurately.

[0014] Preferably, the elastic clip comprises an elastic sheet and a lower clamping jaw, one end of the elastic sheet is connected to the lower surface of the upper pressure plate, the lower clamping jaw is connected to the other end of the elastic sheet corresponding to the upper clamping jaw, and the elastic sheet and the lower clamping jaw are integrally formed.

[0016] Preferably, the front ends of the upper clamping jaw and the lower clamping jaw are provided with a "7"-shaped bending portion, and the center of the bending portion is correspondingly provided with a clamping opening along its axial direction, and the clamping opening can automatically center the clamped buckle cap.

[0017] It should be noted that the design of the "7"-shaped bending portion can make the vertical buckle automatically approach the end of the clamping claw when being clamped, and the setting of the clamping opening can make the vertical buckle automatically centered when clamping. Therefore, through the cooperation of the "7"-shaped bending portion and the clamping opening, the buckle cap of the vertical buckle can be guided into the correct clamping position, and a good centering effect can be maintained even under high-speed operation, thereby improving production efficiency and finished product quality.

[0018] Preferably, the limiting member includes a limiting rod and a positioning plate, the lower end of the limiting rod abuts against the elastic clip, the upper end is set on the positioning plate by a bolt, and the distance between the lower end of the limiting rod and the positioning plate can be adjusted by adjusting the position of the bolt on the limiting rod.

[0019] It should be noted that by adjusting the distance between the lower end of the limit rod and the positioning plate, the clamping device can be installed to adjust the size of the opening between the elastic clip and the upper clamping plate, so as to be suitable for clamping vertical buckle caps of different diameters.

[0020] Preferably, the lifting member comprises a lifting ring and a lifting rod, the lifting ring is arranged on the upper clamping plate between the limiting through hole and the mounting seat, the lifting rod is vertically arranged above the upper clamping plate, and the lower end thereof is hinged to the lifting ring.

[0021] It should be noted that the combined design of the lifting ring and the lifting rod provides a convenient means of control for the operator. By lifting the lifting rod, the upper clamping plate can be driven to rotate around the rotating axis, thereby increasing the distance between the upper clamping plate and the elastic clip, which is convenient for the placement or removal of the vertical buckle. The hinged design of the lifting ring and the lifting rod allows the lifting rod to move freely in the vertical direction while maintaining the connection with the lifting ring, ensuring the smoothness and stability of the lifting action. The lifting device can also be used to automatically control the lifting and lowering of the lifting rod, especially in continuous operation, which can significantly reduce the operator's manual adjustment time and reduce labor intensity.

The limiter is connected to the button sewing machine so that the elastic clip can be set in a fixed position, ensuring the correct position of the elastic clip during the button sewing process, so that the buckle cap of the vertical button can be accurately aligned with the needle hole of the sewing needle, avoiding the problem of the buckle foot being occupied by the clamping plate, which is particularly suitable for vertical buttons with shorter buckle feet. The pulling member is connected to the driving device of the button sewing machine. Through the control of the driving device, the rotation of the upper clamping plate can be automatically controlled, that is, the opening and closing between the upper clamping plate and the elastic clip can be controlled. This process does not require manual adjustment by the operator, which greatly improves production efficiency and convenience of operation; at the same time, due to the cooperation between the lifting member and the driving device, precise control can be achieved to ensure consistent clamping force during each button sewing process, avoiding the displacement of the vertical button due to insufficient clamping force, and ensuring the consistency and high quality of the button sewing effect.

[0025] Preferably, a needle plate is provided below the sewing needle of the button sewing machine, a positioning groove is provided on the needle plate corresponding to the button sewing clamping position, and the end of the elastic clip is correspondingly arranged in the positioning groove.
