[0002] With the rapid development of society, all walks of life are moving towards automation. Of course, button sewing machines are no exception. The common operation method of button sewing machines is the manual button feeding method, which has low efficiency. And for some buttons, holes need to be punched first and then the buttons are sewn on the clothes, which will greatly increase the labor cost and reduce the work efficiency.

[0003] In this regard, Chinese Patent Publication No. CN215881877U discloses "a button sewing machine, including a frame and a moving frame. The moving frame is movably arranged on the frame in the front-back direction. Upper button feeding vibrating discs and lower button feeding vibrating discs are respectively arranged on the left and right sides of the frame. A button placing device is arranged at the middle end of the moving frame. Behind the button placing device, an upper button feeding device and a lower button feeding device fixed on the frame are provided. The upper button feeding device and the lower button feeding device are respectively communicated with the upper button feeding vibrating disc and the lower button feeding vibrating disc through feeding channels. The upper button feeding device is located above the lower button feeding device. An punching device and a button pressing device are also arranged on the moving frame, and the button placing device is located below the punching device and the button pressing device. When the moving frame moves, it drives the punching device, the button pressing device and the button placing device to move synchronously."

[0004] The above patent transports the lower nails through the lower button feeding device, mainly by vibrating the guide material through the vibrating disc. However, the vibrating guide completely depends on the gravity of the button itself to move, and is easily affected by the guide chute. If some impurities fall on the inner wall of the chute, the movement of the button will be blocked, and it is easy to cause the buttons to accumulate in the chute, resulting in the problem of importing multiple buttons at a time during feeding, thus affecting the normal button sewing work.

Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1 to 4 shown, the present utility model provides a nail feeding structure of an automatic button sewing machine, including a first cylinder 2, the first cylinder 2 is fixedly connected to the inner side of the button sewing machine frame 1, the output end of the first cylinder 2 is provided with a feeding assembly 3, the feeding assembly 3 includes a movable plate 31, one end of the movable plate 31 is fixedly connected to the output end of the first cylinder 2, the other end of the movable plate 31 is fixedly connected with a limiting plate 32, the middle part of the movable plate 31 is fixedly connected with a mounting seat 33, one end of the mounting seat 33 is fixedly connected with a second cylinder 34, and the output end of the second cylinder 34 is provided with a material clamping member 35 that clamps the button by abutting against the limiting plate 32.

[0020] By controlling the second cylinder 34, the material clamping member 35 is disengaged from the limit plate 32. Then, the material clamping member 35 guides the lower nails into the outlet end of the corresponding vibrating bowl. Next, control the second cylinder 34 to make the material clamping member 35 approach the limit plate 32, so that the lower nails introduced by the material clamping member 35 abut against the limit plate 32. Thus, both the limit plate 32 and the material clamping member 35 apply pressure to the lower nails and clamp them. Then, control the first cylinder 2 to move the movable plate 31 towards the feeding die 4, which can also convey the lower nails clamped by the limit plate 32 and the material clamping member 35 onto the feeding die 4. Finally, control the second cylinder 34 to disengage the material clamping member 35 from the limit plate 32, causing the lower nails to fall into the feeding die 4. By repeating this cycle, the entire structure can effectively introduce the lower nails into the feeding die 4 one by one, avoiding the problem of introducing multiple lower nails at once and improving the feeding efficiency.

[0021] Among them, the material clamping member 35 includes a connecting seat 351. One end of the connecting seat 351 is fixedly connected with a connecting plate 352. One end of the connecting plate 352 is fixedly connected with the output end of the second cylinder 34. The other end of the connecting plate 352 is fixedly connected with a clamping block 353. The clamping block 353 abuts against the end of the limit plate 32 through the movement of the connecting plate 352. A clamping groove 36 for clamping the nail buckle is formed at one end of the limit plate 32 away from the movable plate 31.

[0022] Among them, the connecting plate 352 is of an L-shaped structure. The vertical section of the connecting plate 352 is fixedly connected with the output end of the second cylinder 34. The horizontal section of the connecting plate 352 is slidably connected with the limit plate 32. The width of the limit plate 32 is the same as that of the connecting plate 352, and both are half of the width of the movable plate 31. The clamping block 353 is perpendicular to the connecting plate 352, and the width of the limit plate 32 is the same as that of the movable plate 31.

[0023] Working principle: First, control the second cylinder 34 to make the clamping block 353 guide the lower nails into the inner side of the clamping block 353 from the outlet end of the corresponding vibrating bowl. Then, control the second cylinder 34 to make the clamping block 353 approach the limit plate 32, so that the lower nails inside the clamping block 353 are clamped into the clamping groove 36 at the end of the limit plate 32. This causes the lower nails to be clamped under the pressure applied by the clamping block 353 and the limit plate 32. Then, control the first cylinder 2 to move the movable plate 31 towards the feeding die 4, which can also convey the lower nails clamped by the limit plate 32 and the material clamping member 35 onto the feeding die 4. Finally, control the second cylinder 34 to disengage the clamping block 353 from the limit plate 32, causing the lower nails to fall into the feeding die 4. By repeating this cycle, the entire structure can effectively introduce the lower nails into the feeding die 4 one by one, avoiding the problem of introducing multiple lower nails at once and improving the feeding efficiency.
