[0001] The present invention relates to the technical field of button sewing machines, and in particular to a feeding device for a button sewing machine. Background Art

[0002] The existing riveting machine, also known as the button sewing machine, is widely used in garment factories and leather bag processing enterprises. It is mainly used to nail various types of metal buttons on knitted garments, down jackets, jeans, shoes and hats, leather and other products.

[0003] When attaching buttons to fabric, holes are usually punched first using a punching machine, and then riveted using a riveting machine. Currently, these two processes are separate, resulting in low efficiency.

[0004] Chinese patent CN202011346513.X discloses a multifunctional riveting machine, whose feeding and loosening device is driven by a cylinder to move horizontally to feed the material. It has a relatively simple function, cannot achieve automatic reset and clamping, and has poor stability.

[0005] Chinese patent CN202222669468.2 discloses a new type of button riveting machine, whose punching and riveting mechanism has a relatively complex structure and realizes vertical movement through multiple swinging parts, resulting in a high failure rate. Summary of the Invention

[0021] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, a feeding device of a button sewing machine includes a feeding drive mechanism 5, a primary transmission mechanism 6 and a secondary transmission mechanism 7. The feeding transmission mechanism first drives the clamping part 61 of the primary transmission mechanism 6 to move forward, and then drives the bearing part 71 of the secondary transmission mechanism 7 to move forward. At this time, the primary transmission mechanism 6 and the secondary transmission mechanism 7 move synchronously.

[0023] Specifically, the feeding drive mechanism 5 includes a feeding drive member 51, a feeding fork 53 and a feeding slider 55. The feeding drive member 51 is arranged in the frame 1 and has a feeding output shaft 52. The upper end of the feeding fork 53 is hinged in the frame 1, and the feeding output shaft 52 is connected to the middle part of the feeding fork 53. The feeding drive member 51 can drive the feeding fork 53 to rotate around the hinge point through the feeding output shaft 52. The lower end of the feeding fork 53 is arc-shaped and has a movable groove 54. The movable groove 54 is an annular groove. The feeding slider 55 is arranged on the frame 1 through a feeding slide rail. The front end of the feeding slider 55 is provided with an abutment portion 57, and the side end is provided with a movable portion 56. The movable portion 56 is movably placed in the movable groove 54, so that the feeding fork 53 can push the feeding slider 55 to move horizontally.

[0024] Furthermore, the feeding drive member 51 can be set as a driving cylinder or a driving motor. When the feeding drive member 51 is set as a driving cylinder, it can control the feeding output shaft 52 to move forward and backward and push the middle part of the feeding fork 53 to move, so as to realize the rotation of the feeding fork 53 around the hinge point, thereby realizing the forward and backward movement of the lower end of the feeding fork 53.

[0025] When the feeding drive member 51 is set as a driving motor, a feeding turn block is provided on the outer sleeve of the feeding output shaft 52. The driving motor drives the feeding turn block to rotate through the feeding output shaft 52. The feeding turn block and the middle part of the feeding fork 53 are connected by a feeding transmission rod, thereby driving the lower end of the feeding fork 53 to move forward and backward through the feeding transmission rod.

[0026] like Figure 2 As shown, the primary transmission mechanism 6 includes a transmission base 63, a first fixed block 64, a first feed push block 65, a first feed pull block 66, a clamping portion 61 and a first spring 62. The first fixed block 64 is arranged at the front end of the transmission base 63, the first feed push block 65 is movably arranged at the rear end of the transmission base 63, the first feed pull block 66 is arranged at the rear end of the first feed push block 65, the clamping portion 61 is arranged at the front end of the first feed push block 65, and the two ends of the first spring 62 are respectively connected to the first fixed piece and the first feed push block 65. The first spring 62 is used to make the first feed push block 65 always have a tendency to move forward, thereby To achieve the forward movement of the clamping part 61, a first guide column 67 is provided in the transmission base 63, and the lower end of the first feed push block 65 is sleeved outside the first guide column 67. The first feed pull block 66 has a long groove, and the feed slider 55 is movably engaged in the long groove. The feed slider 55 can drive the first feed pull block 66 to follow the movement by moving backward, thereby achieving the retreat of the clamping part 61. During this process, the first spring 62 is gradually stretched, and when the feed slider 55 moves forward, the first feed push block 65 automatically moves forward under the elastic force of the first spring 62 until the first feed push block 65 abuts against the rear end of the transmission base 63.

[0027] like Figure 3As shown, the secondary transmission mechanism 7 includes a bearing portion 71, a second feeding push block 73, a second spring 72, a second fixed block 74 and a second mounting portion 75. The second feeding push block 73 is movably arranged on the transmission base 63. The bearing portion 71 is arranged at the front end of the second feeding push block 73. The two ends of the second spring 72 are respectively connected to the second feeding push block 73 and the frame 1. The second spring 72 is used to make the second feeding push block 73 always have a tendency to move backward. The second fixed block 74 is arranged at the front end of the transmission base 63. The second mounting portion 75 is arranged at the front end of the second feeding push block 73 for mounting the bearing portion 71. When 53 is not moving, the second mounting portion 75 abuts against the second fixed block 74. At this time, the second spring 72 is in a stretched state. As the feed fork 53 moves forward, the clamping portion 61 places the nail button into the bearing portion 71, and the abutting portion 57 set at the front end of the feed slider 55 abuts against the rear end of the second feed push block 73. Then the feed fork 53 continues to push the second feed push block 73 to move until the bearing portion 71 is pushed to the riveting position 11. When the feed fork 53 moves backward, the second feed push block 73 automatically retreats and resets under the elastic force of the second spring 72 until the second mounting portion 75 abuts against the second fixed block 74.

[0028] Furthermore, in order to increase the stability of feeding, the travel rhythm can be changed by adjusting the length of the first feeding push block 65 and the second feeding push block 73. For example, after the clamping part 61 is placed in the rivet, the feeding slider 55 continues to move a certain distance before the abutment part 57 set at the front end of the feeding slider 55 abuts against the second feeding push block 73, which can effectively improve the stability of the rivet transportation.
