DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] The following further describes in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0035] As Figure 1As shown in the figure, a feeding device of a button sewing machine is slidably mounted on the button sewing machine and includes: a clamping rod 1, with a clamping groove 31 provided at its front end. The clamping rod 1 is slidably mounted on the button sewing machine and is driven by a driving source (cylinder or linear motor) on the button sewing machine to move the clamping rod 1 back and forth on the button sewing machine; a jaw member 2, which is slidably arranged at the side end of the clamping rod 1, and a jaw portion 41 is provided at the front end of the jaw member 2. The jaw portion 41 is located in front of the clamping groove 31; a driving member 5, which is mounted on the clamping rod 1, and the driving end of the driving member 5 is movably connected to the rear end of the jaw member 2. The driving member 5 is a driving cylinder or a linear motor; by driving the jaw member 2 to move linearly on the clamping rod 1, the jaw portion 41 is close to the clamping groove 31, so as to clamp the workpiece located at the clamping groove 31; after the feeding device feeds the workpiece to the riveting seat of the button sewing machine, the driving member 5 makes the jaw member 2 move forward, so that the jaw portion 41 is away from the clamping groove 31, realizing the release of the workpiece and ensuring that the workpiece can fall onto the riveting seat.

[0036] The feeding device of this design scheme is mounted on the button sewing machine and is used for clamping and transporting the lower button; the feeding device is slidably arranged on the guide rail of the button sewing machine and is driven by the cylinder of the button sewing machine to move on the guide rail, so as to transport the clamped workpiece to the riveting seat of the button sewing machine; a base is provided on the button sewing machine, and the base is located at the lower end of the feeding device and is used to support the lower end of the lower button. The base moves on the guide rail following the feeding device.

[0037] Combined with Figure 2 and Figure 5 , a sliding groove 21 is provided at the side end of the jaw member 2, and a sliding block 6 is provided at the side end of the clamping rod 1. The sliding block 6 is slidably placed in the sliding groove 21, realizing the sliding connection of the jaw member 2 on the clamping rod 1. The sliding groove 21 and the sliding block 6 cooperate to ensure the stability of the jaw member 2 when sliding.

[0038] Combined with Figure 2 and Figure 5 , an anti - detachment groove 22 is provided on the inner wall of the sliding groove 21, and an anti - detachment protrusion 61 is provided at the front end of the sliding block 6; when the sliding block 6 is slidably placed in the sliding groove 21, the anti - detachment protrusion 61 is placed in the anti - detachment groove 22, thus preventing the sliding block 6 from detaching from the notch of the sliding groove 21 and ensuring the stability of the connection between the jaw member 2 and the clamping rod 1.

[0039] As shown in Figure 5As shown, the rear end of the slider 6 has a fixing part 62. A fixing groove 11 is formed on the clamping rod 1. The fixing part 62 is inserted into the fixing groove 11. The end of the fixing member 12 passes through the side wall of the fixing groove 11 and is connected to the fixing part 62. The fixing member 12 is a rivet or a screw or a bolt. In this solution, connection holes are formed on the upper and lower side walls of the fixing groove 11. The fixing member 12 sequentially passes through the connection hole on the upper side wall, the fixing part 62, and the connection hole on the lower side wall. The two ends of the fixing member 12 are fixed on the edge of the connection hole by riveting, so as to realize the connection of the fixing part 62 in the fixing groove 11. The shapes of the fixing part 62 and the fixing groove 11 are adapted to each other.

[0040] Combined with Figure 1 and Figure 2 , the front end of the clamping rod 1 is movably connected with a clamping block 3. The front end of the clamping block 3 is formed with the clamping groove 31 described above. An adjustment hole one 32 is arranged on the clamping block 3. The adjustment hole one 32 is an oblong hole or a relatively large hole for the fastener one 13 to move therein. The end of the fastener one 13 passes through the adjustment hole one 32 and is connected to the front end of the clamping rod 1. The fastener one 13 is a bolt or a screw or a bolt. The convex part at the end of the fastener one 13 abuts against the edge of the adjustment hole one 32.

[0041] Combined with Figure 2 and Figure 4 , a limiting groove one 33 is arranged on the clamping block 3. The adjustment hole one 32 is formed at the bottom of the limiting groove one 33. A limiting block 14 is arranged at the front end of the clamping rod 1. The limiting block 14 is inserted into the limiting groove one 33. The limiting block 14 is movably connected to the fastener one 13 extending out of the adjustment hole one 32. When the clamping block 3 adjusts its position on the clamping rod 1, the limiting block 14 linearly slides back and forth in the limiting groove one 33, ensuring that the clamping block 3 can only move back and forth during adjustment, avoiding the rotation or left - right movement of the clamping block 3 on the clamping rod 1, and ensuring the stability of the connection.

[0042] Combined with Figure 1 , Figure 2 and Figure 4, a material blocking portion 15 is provided at the side end of the limit block 14, and an avoidance opening 34 is provided at the side end of the clamping block 3; when the limit block 14 is inserted into the first limit groove 33, the material blocking portion 15 is placed in the avoidance opening 34, so that the side wall of the material blocking portion 15 or the side wall of the clamping block 3 can movably block the protruding column at the upper end of the workpiece transported subsequently. Since the feeding device will move on the buttoning machine, the buttons on the conveying guide rail at its side end will abut against the side end of the clamping rod 1 of the feeding device. After the clamping block 3 adjusts its position at the front end of the clamping rod 1, a gap will appear between the rear end of the clamping block 3 and the front end of the clamping rod 1. When the feeding device moves backward, the workpiece (button) will be stuck in this gap, resulting in the jamming of the machine and causing the problem of inability to feed. The cooperation of the material blocking portion 15 and the avoidance opening 34 ensures that the button will abut against the side end of the material blocking portion 15 or the side end of the clamping block 3, avoiding the jamming of the button and ensuring the stability of feeding.

[0043] Combined with Figures 1 to 3 , the front end of the jaw member 2 is movably connected with an adjusting jaw 4, and a jaw portion 41 is formed by bending at the front end of the adjusting jaw 4; an adjusting hole two 42 is provided on the adjusting jaw 4, and at least one fixing hole 25 is provided at the front end of the jaw member 2. The end of the second fastener 23 passes through the adjusting hole two 42 and is connected in the fixing hole 25. The second fastener 23 is a bolt or a screw or a pin. When there are multiple fixing holes 25, the position of the adjusting jaw 4 at the front end of the jaw member 2 is adjusted by connecting the second fastener 23 with the fixing holes 25 at different positions, so as to adjust the distance between the jaw portion 41 and the clamping groove 31, thereby ensuring that buttons of different sizes can be clamped.

[0044] Combined with Figure 2 and Figure 3 , a second limit groove 43 is provided on the adjusting jaw 4, and an adjusting hole two 42 is provided at the bottom of the second limit groove 43. The front end of the jaw member 2 has a limit portion 24, and the limit portion 24 is inserted into the second limit groove 43 and movably connected with the second fastener 23. When the adjusting jaw 4 adjusts its position on the jaw member 2, the limit portion 24 moves in the second limit groove 43, and the sway of the adjusting jaw 4 on the jaw member 2 is restricted by the adaptation of the second limit groove 43 and the limit portion 24, ensuring the stability of the connection.

[0045] Combined with Figures 1 to 3 , the clamping groove 31 is a V-shaped groove, and its groove opening faces the jaw portion 41, which is used to ensure the accuracy of restricting the workpiece in the clamping groove 31.

[0046] Combined with Figure 1 and Figure 2 , the chute 21 conducts to the rear end of the jaw member 2. The rear end of the jaw member 2 has a bent portion 26, and the bent portion 26 is movably connected with a connecting block 7 by a bolt. One end of the connecting block 7 is located at the rear end of the chute 21, which is used to prevent the slider 6 from sliding out of the chute 21. The connecting block 7 is movably connected with the driving end of the driving member 5.

[0047] As shown Figure 2 in the figure, a connecting seat 16 is convexly provided at the side end of the clamping rod 1. A fixing seat 8 is bolted to the clamping rod 1. A connecting groove is formed between the front end of the fixing seat 8 and the connecting seat 16. The driving member 5 is placed in the connecting groove and clamped and fixed by both the fixing seat 8 and the connecting seat 16.
