[0001] The utility model relates to the technical field of button sewing machines, and more specifically, the utility model relates to a dust-proof structure for an automatic button sewing machine. Background Art

[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 mode of button sewing machines is the manual button feeding method. The manual button feeding method is inefficient, and some buttons need to be punched first and then sewn on the clothes. At present, many automatic button sewing machines have emerged on the market, greatly improving the work efficiency.

[0003] For example, the Chinese patent publication number 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 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 arranged. 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] Although this patent can automatically sew buttons on clothes in an automated manner, during the button sewing process, many cut clothing threads will fall onto the button die base. Once these threads easily fall into the interior of the frame through the holes and grooves of the top die mechanism, this makes the subsequent cleaning work very troublesome and affects the normal operation of the button sewing machine.
