The automatic feeding device 2 includes a fixed base 20 and a conveying panel 21 disposed on the fixed base 20 and slidably arranged left and right. A lower drive roller 22 is disposed at the discharge end of the conveying panel 21. An L-shaped fixed plate 12 is disposed on the buttonhole machine body 10. A first guide is disposed at the bottom of the fixed plate 12. The first guide rail 13 has a first slider 14 that is slidably coupled to the left and right. The first slider 14 has a crossbar 23. One end of the crossbar 23 near the main body 10 of the buttonhole machine has a vertical bar 24 that is engaged with the pressure plate 11. The other end has a rotating bracket 25 that is rotatably coupled to the top and bottom. One end of the rotating bracket 25 extends above the lower transmission roller 22. At the bottom of the rotating bracket 25 is an upper transmission roller 26 that is rotatably coupled to the lower transmission roller 22. The upper transmission roller 26 is located above the lower transmission roller 22 and is in a gap-fitting arrangement with the lower transmission roller 22.

[0018] Furthermore, a fixing rod 3 is provided on the side of the fixed base 20 away from the buttonhole machine body 10. A top plate 30, spaced apart from the fixed base 20, is provided at the end of the fixing rod 3. A cylinder-driven feed rod 54 is provided at the end of the fixed base 20 near the top plate 30. The feed rod 54 can slide to engage with the top rod. An air nozzle for feeding is also provided at one end of the fixed base 20. Through the cooperation of the feed rod 54 and the top plate 30, the sewn fabric is pressed onto the top rod by the feed rod 54, and then blown by the air nozzle from between the upper drive roller 26 and the lower drive roller 22 onto the top rod for collection, which is very practical.

[0019] Furthermore, the fixed base 20 is provided with two second guide rails 200 spaced apart, and a second slider 201 that slides with the second guide rails 200 is provided at the bottom of the conveying panel 21. A transmission belt 6 is provided inside the fixed base 20, extending along the length of the conveying panel 21. A drive block 60 is fixed to the transmission belt 6, and the end of the drive block 60 is fixedly connected to the bottom of the conveying panel 21. A first drive motor 202 and a belt fixing seat 203 are provided inside the fixed base 20. One end of the transmission belt 6 is connected to the first drive motor 202 in a transmission connection, and the other end is rotatably connected to the belt fixing seat 203. The cooperation of the second guide rails 200 and the second slider 201 enables stable left-right driving of the conveying panel 21, resulting in better synchronization.

[0020] Furthermore, the upper end of the buttonhole machine body 10 is provided with a fixed panel 7 located above the upper transmission roller 26. A drive cylinder 70 is hinged to the bottom of the fixed panel 7, and a universal joint 71 is provided on the output shaft of the drive cylinder 70. A connecting seat 72, which is rotatably connected and fixed to the universal joint 71, is provided at the end of the rotating bracket 25. By providing a drive cylinder 70, it is possible to easily rotate and lift the rotating bracket 25 when laying the fabric, so that the fabric can be laid flat on the conveying panel 21, making the operation more convenient.

[0021] Furthermore, a second drive motor 212 is fixed to the bottom of the conveying panel 21 inside the fixed base 20. A drive belt 213 is provided on the output shaft of the second drive motor 212. A gear 220 that is in transmission cooperation with the drive belt 213 is provided at one end of the lower transmission roller 22.

[0022] Furthermore, the crossbar 23 is provided with two rotating seats 8 spaced apart, one end of the rotating bracket 25 is located between the two fixed seats, and a fixed shaft 80 passing through the rotating bracket 25 is provided on the two rotating seats 8.

[0023] Furthermore, the discharge end of the conveying panel 21 is provided with an installation opening 210 for mounting the lower drive roller 22, and lower mounting seats 211 are provided on both sides of the lower drive roller 22 at the bottom of the conveying panel 21. The lower drive roller 22 is rotatably fixed to the lower mounting seats 211. The lower mounting seats 211 enable stable rotation of the lower drive roller 22.

[0024] Furthermore, the bottom of the rotating bracket 25 is provided with upper mounting seats 250 located on both sides of the upper drive roller 26, and the upper drive roller 26 is rotatably fixed to the upper mounting seats 250. The upper mounting seats 250 enable stable rotation of the upper drive roller 26.

[0025] Working Principle: When using this buttonhole machine, first lay the fabric flat on the conveyor panel 21, then pass one end of the fabric between the upper drive roller 26 and the lower drive roller, and press the side of the fabric to be sewn into the buttonhole under the pressure plate 11 of the buttonhole machine body 10. When the buttonhole machine body 10 starts sewing, the pressure plate 11 will drive the fabric to move left and right to sew the buttonhole. When the pressure plate 11 moves left and right, it will drive the vertical rod 24 to move left and right. When the vertical rod 24 moves, it will drive the horizontal rod 23 to move left and right on the first guide rail 13. At this time, the rotating bracket 25 set on the horizontal rod 23 will also drive the upper drive roller 26 to move left and right. During this process, the conveyor panel 21 slides left and right along the fixed base 20 via the drive belt 6, thereby driving the lower drive roller 22 and the fabric to slide left and right synchronously. This ensures that during the buttonhole sewing process, the upper drive roller 26 and the lower drive roller 22 can always cooperate with the pressure plate 11 to press the fabric onto the conveyor panel 21 for stable left and right sliding and buttonhole sewing. When one buttonhole is sewn, the second drive motor 212 is started, which drives the lower drive roller 22 to rotate via the drive belt 213. During the rotation of the lower drive roller 22, the fabric is moved a certain distance with the cooperation of the upper drive roller 26 to sew the next buttonhole. The entire operation does not require manual feeding and sewing, achieving fully automatic continuous buttonhole sewing.

[0026] This practical buttonhole machine uses an automatic feeding device 2, which can achieve continuous feeding and effectively improve the processing efficiency of the buttonhole machine.
