[0002] In the garment and bag manufacturing industries, automatic button sewing machines are widely used for the automatic sewing of various types of buttons, and the feeding device is used to continuously feed metal buttons.
[0003] Currently, most automatic button-attaching machines have feeding mechanisms designed for specific models or single-direction button bodies, resulting in poor versatility. In actual production, button bodies often come in various shapes, commonly resembling the "I" shape or having an asymmetrical structure. There may also be differences in the direction of the front and back, or the wide and narrow ends. In some cases, due to static electricity or stacking methods, double-layer button bodies may overlap and enter the feeding channel, which can easily lead to jamming, missed feeding, or incorrect orientation. This requires frequent machine stops and manual intervention, seriously affecting the continuity and efficiency of automated production.
[0004] Therefore, an automatic button-attaching machine's feeding device is needed to improve the above-mentioned problems. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] Please see Figure 1-3 This utility model provides a technical solution: For an example, please refer to... Figure 1 , 23. A feeding device for an automatic button attaching machine includes a feeding tray 1, which has a conveying track inside that spirals upward from the bottom to the top. After a large number of buttons are fed into the feeding tray 1, the buttons move upward in an orderly manner along the conveying track under external drive. In order to overcome the problems of chaotic button orientation, easy stacking and blockage, and inconsistent discharge direction in traditional devices, this device integrates a button face front and back screening part, an anti-stacking part, and a direction adjustment part on the conveying path.
[0024] The buckle front and back screening section includes at least two screening grooves 4 machined on the side of the conveyor track. The cross-section of the grooves 4 is preferably triangular. An adjustable guide is installed nearby to guide the buckle body to the edge of the screening groove 4. Specifically, the guide can be a material guide piece b6. One end of the material guide piece b6 is fixed to the base of the feeding tray 1 by screws or other means, and the other end has a protrusion extending towards the center of the tray. This protrusion extends exactly to the side of the screening groove 4. When the buckle body is conveyed to this position along the track, the protrusion of the material guide piece b6 will interfere with the movement trajectory of the buckle body. For buckles body facing the required direction... The buckle body is wider at the top and narrower at the bottom. If the orientation is correct, it can smoothly pass through the screening groove 4 along the protrusion. If the orientation is incorrect, it will fall back to the bottom of the tray from the groove 4 when guided by the material guide plate b6 to the edge of the groove 4, thus achieving automatic screening. In order to adapt to buckle bodies of different sizes or types, the screening sensitivity needs to be adjustable. A hand screw 5 is also threaded on the side of the feeding tray 1. The end of the hand screw 5 directly abuts against the side of the protrusion of the material guide plate b6. By turning the hand screw 5, the material guide plate b6 can be pushed or released slightly, thereby changing the depth of its protrusion into the conveyor track, and finally achieving fine adjustment of the screening degree.
[0025] Please refer to Figure 1 , 2 To prevent the fasteners from stacking during vibratory conveying, an anti-stacking section is provided, including a protruding edge 3. This protrudes from the surface of the conveyor track and, together with the outer wall of the loading tray 1, forms an inclined conveying section with a cross-section that is higher on the outside and lower on the inside. This causes the fasteners to tend to move towards the inner inclined wall of the loading tray 1 under the action of gravity during conveying, thus straightening the queue in the lateral direction. To further solve the problem of longitudinal stacking, a serrated plate 10 is provided in the middle section of the protruding edge 3. The serrated plate 10 has a waist-shaped hole, through which screws are inserted to connect with the loading tray. The tray 1 is fixedly connected and can be adjusted according to different buckles. A slot 8 is opened on the tray body of the feeding tray 1. A buckle plate 9 is installed in this slot 8 by screws passing through its own waist-shaped hole. The inner side of the buckle plate 9 is designed to be arc-shaped. When the buckles pass through in a single row, they can pass smoothly from below. If two buckles are stacked, when they pass through the serrated plate 10, the buckles are screened because the widths of different parts are different. The function of the buckle plate 9 is to make the buckles that pass through the serrated plate 10 stand upright so as to screen the stacked buckles.
[0026] Please refer to Figure 1 , 2 3. The direction adjustment section includes a short upper buckle track, including a buckle plate b12, which is installed on the upper buckle short track and its position can be adjusted through the waist-shaped hole on it. The buckle plate a11 is installed through another mounting groove 15 opened at the discharge port and is presented at a certain tilt angle. The buckle plate a11 is also fixed in position through the waist-shaped hole. The buckle plate a11 and the buckle plate b12 are set opposite to each other, and the gap between them forms a buckle body adjustment channel 13. By adjusting the position of the two buckle plates respectively, the width, direction and exit angle of this channel can be precisely changed. In the final stage of leaving the feeding plate 1, the buckle body passes through the channel and its posture is corrected, so that it enters the subsequent upper buckle vibrating plate track 2 in a completely uniform direction, preparing for precise buckle fastening.
[0027] To improve the conveying efficiency of the buckle body on the spiral track, multiple material feeding plates 7 can be set at intervals on the track. To enhance the overall structural strength of the feeding plate 1 and prevent deformation caused by long-term vibration, multiple reinforcing ribs 14 can be set on its outer side.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
