[0029] The connecting plate 100 is arranged vertically, and the horizontal sliding mechanism 110, the positioning clamping mechanism 200 and the linear driving mechanism 400 are all arranged on the side of the connecting plate 100. The connecting plate 100 is arranged below the workbench, and the connecting plate 100 is slidably connected to the main body of the back buckle machine, so that the material transfer mechanism can carry the back sheet and the back buckle to move, and the material transfer mechanism can move the back sheet and the back buckle from the loading station to the sewing station.

[0030] The horizontal sliding mechanism 110 includes a first slide rail and a first slider that cooperate with each other. The first slide rail is horizontally arranged on the side of the connecting plate 100. The positioning clamping mechanism 200 is located on the extension line of the first slide rail, and the movable clamping mechanism 300 is arranged on the first slider.

[0031] In some of the embodiments, the movable clamping mechanism 300 also includes a horizontal sliding plate 320, the output end of the linear drive mechanism 400 is connected to the horizontal sliding plate 320, the movable hook 310 is arranged on the horizontal sliding mechanism 110 through the horizontal sliding plate 320, the linear drive mechanism 400 drives the horizontal sliding plate 320 to move in the horizontal direction, and the horizontal sliding plate 320 carries the movable hook 310 to move in the horizontal direction, so that the movable hook 310 is close to or away from the positioning hook 210.

The hook portion of the movable hook 310 can pass through the guide hole and extend to the top of the workbench, ensuring that the movable hook 310 can hook the back sheet and the back buckle and press the back sheet and the back buckle on the workbench.

[0033] The horizontal sliding plate 320 is connected to the first lifting plate 330 through the first lifting sliding mechanism 322, and the first lifting sliding mechanism 322 can reduce the resistance encountered by the lifting and moving of the first lifting plate 330. The first lifting sliding mechanism 322 includes a second slide rail and a second slider that cooperate with each other, the second slide rail is vertically arranged on the first lifting plate 330, and the second slider is connected to the first lifting plate 330. First, the movable hook 310 is rotatably installed on the first lifting plate 330, and then the height of the first lifting plate 330 is adjusted to complete the height adjustment of the movable hook 310, and then the first lifting plate 330 is fixed on the horizontal sliding plate 320.

[0034] It can be imagined that the second slider or the first lifting plate 330 is threadedly connected with a screw or a screw rod. By turning the screw or the screw rod, the screw or the screw rod is pressed against the horizontal sliding plate 320, so as to fix the height position of the first lifting plate 330 and the movable hook 310 on the horizontal sliding plate 320, and ensure that the hook portion of the movable hook 310 can pass through the guide hole and extend to the top of the workbench, and the movable hook 310 can hook the back sheet and the back buckle and press the back sheet and the back buckle onto the workbench.

[0035] In some of the embodiments, a first lifting block 321 is provided on the horizontal sliding plate 320. The first lifting block 321 can extend into the guide hole. The first lifting block 321 is located below the hook portion of the movable hook 310.

The first lifting block 321 can block the area of ​​the guide hole that is opposite to the hook portion of the movable hook 310, thereby preventing the back sheet and the back buckle from being pressed into the guide hole by the hook portion of the movable hook 310.

[0036] It is understandable that there are two first lifting blocks 321, and the two first lifting blocks 321 can be arranged along the length direction of the guide hole to ensure that the length of the guide hole is long enough to prevent the back sheet and the back buckle from entering the guide hole from top to bottom. The upper surface of the first lifting block 321 is flush with the upper surface of the workbench.

[0037] In some embodiments, the movable hook 310 includes a first driving mechanism 311, a rotating arm 312 and a hook plate 313, the middle part of the rotating arm 312 is hinged to the first lifting plate 330, the first driving mechanism 311 is hinged to the first lifting plate 330, the output end of the first driving mechanism 311 is hinged to one end of the rotating arm 312, the other end of the rotating arm 312 is connected to the hook plate 313, the first driving mechanism 311 drives the rotating arm 312 and the hook plate 313 to rotate, the hook plate 313 performs a circular motion, the hook plate 313 passes through the guide hole from bottom to top and extends to the top of the workbench, and then one end of the hook plate 313 descends and hooks the back sheet and back buckle on the workbench. One end of the hook plate 313 is the hook part of the movable hook 310, which is used to hook on the back sheet and back buckle and press the back sheet and back buckle on the workbench. The middle part of the rotating arm 312 is hinged to the first lifting plate 330 through the first hinge shaft.

[0038] It can be understood that the other end of the rotating arm 312 is connected to the middle part of the hook plate 313, and the other end of the rotating arm 312 is perpendicular to the hook plate 313. When the rotating arm 312 rotates, one end of the hook plate 313 first passes through the guide hole from bottom to top and extends to the top of the workbench until the other end of the rotating arm 312 forms an angle of 45° with the horizontal plane, and one end of the hook plate 313 moves to the highest position. The rotating arm 312 continues to rotate, and one end of the hook plate 313 begins to move from bottom to top until the other end of the rotating arm 312 is in a vertical state. The connection point between the other end of the rotating arm 312 and the hook plate 313 is at the highest position and above the workbench. At this time, one end of the hook plate 313 will be hooked on the back sheet and back buckle on the workbench.

[0040] In some of the embodiments, an anti-slip mechanism is provided on the side of the hook plate 313 facing the rotating arm 312, and the hook plate 313 is pressed on the back sheet and the back buckle through the anti-slip mechanism.

[0041] It is conceivable that the anti-skid mechanism is an anti-skid pattern.

[0042] In some of the embodiments, the linear drive mechanism 400 includes a motor 410, a lead screw 420 and a lead screw nut provided on the lead screw 420, the lead screw 420 is rotatably provided on the connecting plate 100, the motor 410 is provided on the connecting plate 100, the output end of the motor 410 is transmission-connected to the lead screw 420, the lead screw nut is connected to the horizontal sliding plate 320, the motor 410 drives the lead screw 420 to rotate, and under the guiding action of the horizontal sliding mechanism 110, the lead screw 420 drives the lead screw nut and the horizontal sliding plate 320 to move.

[0044] In some of the embodiments, the positioning and clamping mechanism 200 also includes a second lifting plate 220 and a second driving mechanism 230. The second lifting plate 220 can be lifted and lowered on the connecting plate 100, and the second lifting plate 220 can be lifted and lowered on the connecting plate 100 to adjust the height of the second lifting plate 220.

[0045] The second driving mechanism 230 is hinged on the second lifting plate 220, the middle part of the positioning hook 210 is hinged to the second lifting plate 220, the output end of the second driving mechanism 230 is hinged to one end of the positioning hook 210, and the other end of the positioning hook 210 is provided with a hook.
