A pressing plate for driving the riveting die head to press down synchronously and a downward pressing air cylinder for driving the pressing plate to act are further arranged on the frame.

[0029] Through the above technical solution, when punching the fabric, the longitudinal driving assembly pulls the moving frame backward, so that the connecting chuck on the punching die head is stuck into the connecting card slot. At this time, the riveting die head will be stuck into the pressing plate. Under the action of the downward pressing power head, the punching die head presses down to punch the fabric. During this process, the downward pressing air cylinder acts synchronously to press down the riveting die head to suck the face buckle on the face buckle mold, so as to realize the synchronous operation of fabric punching and face buckle grasping, greatly improving the processing efficiency.

[0030] After the fabric punching is completed, the punching die head and the riveting die head reset under the action of the second elastic member.

[0031] When performing surface snap riveting, the longitudinal drive assembly pushes the moving frame forward, causing the connecting chuck on the riveting die head to snap into the connecting slot.

The lifting assembly 62 includes a lifting plate 621 fixed to the bottom buckle conveying frame 612, a fixing plate 622 fixed to the second mounting bracket 611, and a second adjusting screw 623 threadedly connected to the fixing plate 622 and its end rotatably connected to the lifting plate 621. By rotating the second adjusting screw 623, the lifting plate 621 can be lifted, thereby lifting the bottom buckle conveying frame 612, so that the height of the second feeding groove 614 is increased; by rotating the second adjusting screw 623 in the reverse direction, the height of the second feeding groove 614 can be reduced, realizing the adaptive adjustment of the height of the second feeding groove 614.

[0067] See the attachment Figure 8, the bottom buckle pushing component 63 includes a moving plate 631 slidably connected to the frame 1, a bottom buckle clamping portion 632 provided on the moving plate 631, and a second driving portion 633 for driving the moving plate 631 to move towards the punching and feeding module 3. The bottom buckle clamping portion 632 includes a first clamping plate 6321 fixed to the moving plate 631, and a second clamping plate 6322 rotatably connected to one side of the first clamping plate 6321 in the middle. The second clamping plate 6322 is equivalent to a lever structure. An end of the first clamping plate 6321 is provided with a bottom buckle clamping opening 6323 for connecting to the second feeding groove 614. One end of the second clamping plate 6322 is provided with a pressing plate 226 end for pressing the bottom buckle at the bottom buckle clamping opening 6323, and the other end of the second clamping plate 6322 is provided with a driving end 6325. A compression spring 6326 is further provided between the driving end 6325 of the second clamping plate 6322 and the first clamping plate 6321. The moving plate 631 is provided with a push block 6327 for squeezing the driving end 6325 to open the bottom buckle clamping opening 6323 and a pushing cylinder 6328 for driving the push block 6327 to move. The compression spring 6326 makes the pressing plate 226 end always press at the bottom buckle clamping opening 6323. Initially, the push block 6327 presses the driving end 6325, and the pressing plate 226 end is opened to facilitate the bottom buckle to enter the bottom buckle clamping opening 6323. When the bottom buckle in the second feeding groove 614 enters the bottom buckle clamping opening 6323, the pushing cylinder 6328 retracts, and the push block 6327 disengages from the driving end 6325, so that the pressing plate 226 end buckles at the bottom buckle clamping opening 6323, and the bottom buckle is clamped. Then the second driving portion 633 pushes the moving plate 631 to drive the bottom buckle clamping portion 632 to move towards the punching and feeding module 3. When the movement reaches the position, the pushing cylinder 6328 moves forward again, the push block 6327 presses the driving end 6325, and the pressing plate 226 end opens the bottom buckle clamping opening 6323 to make the bottom buckle fall into the designated position.

[0068] Combined with the attached Figure 8 and 9 , the punching and feeding module 3 includes a third mounting frame 31 provided below the head mechanism 2, a die holder 32 provided on the third mounting frame 31, and a top-up component 33 for top-up the bottom buckle. The third mounting frame 31 is provided with a sliding guide rail 34, and the die holder 32 is slidably connected to the sliding guide rail 34. The frame 1 is further provided with a third driving portion 35 for driving the die holder 32 to move. The top of the die holder 32 is provided with a backing plate 36, and the backing plate 36 is provided with a bottom buckle hole 361 and a fabric punching hole 362. During operation, the fabric punching hole 362 is aligned with the punching die head 212, and the bottom buckle hole 361 is aligned with the riveting die head 213. The third driving portion 35 drives the die holder 32 to reciprocate to switch back and forth between punching and bottom buckle feeding.

[0069] Among them, the upper top component 33 includes a support column 331 passing through the bottom of the die holder 32, a driving block 332 slidably connected to the bottom of the support column 331, and a fourth driving part 333 for pushing the driving block 332 to move upward to support the column 331. A guiding inclined surface 334 for cooperating with the bottom of the support column 331 is provided on the driving block 332. After the bottom buckle is sent to the support column 331 by the bottom buckle pushing assembly 63, the fourth driving part 333 drives the driving block 332 to move forward, and the support column 331 is lifted through the guiding inclined surface 334, so as to push the bottom buckle into the bottom buckle hole 361 for the riveting die head 213 to suck.

[0070] The working process of the button sewing machine is described below:

[0071] Initially, the downward pressing power head 221 is located above the punching die head 212, the fabric punching hole 362 is aligned with the punching die head 212, and the riveting die head 213 is clamped into the pressing plate 226.

[0072] During operation, the top button feeding mechanism 4 and the bottom button feeding mechanism 6 operate simultaneously.

[0073] First, the top button feeding mechanism 4 pushes a single top button into the top button die 45 for the riveting die head 213 to suck; the bottom button clamp 6323 in the bottom button pushing assembly 63 grabs the bottom button sent by the bottom button conveying assembly 61 and pushes the bottom button to the support column 331 for standby.

[0074] Then, the downward pressing power head 221 drives the punching die head 212 to press down and punch the fabric; synchronously, the pressing plate 226 drives the riveting die head 213 to press down to suck the top button on the lower top button die 45 directly below.

[0075] Then, the punching die head 212 and the riveting die head 213 are reset, and the third driving part 35 drives the die holder 32 to move so that the bottom button hole 361 is aligned with the riveting die head 213.

[0076] After that, the fourth driving part 333 pushes the driving block 332 to drive the support column 331 to rise, so that the bottom button is located in the bottom button hole 361 for standby; the first driving motor 233 drives the die head assembly 21 to move forward so that the downward pressing power head 221 is located directly above the riveting die head 213.

[0077] Finally, the downward pressing power head 221 drives the riveting die head 213 to press down, so that the top button and the bottom button are riveted to the fabric.

[0078] In this way, the automatic button sewing is repeated in a cycle.

[0079] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
