[0029] The feeding adjusting assembly 4 comprises a synthetic leather support plate 401 provided at the top end of the punching support table 1, a punching support plate 402 provided at the top end of the synthetic leather support plate 401, two side fixing plates 403 symmetrically provided on the two sides of the punching support plate 402, two side connecting blocks 404 symmetrically provided on the two sides of the synthetic leather support plate 401, an adjusting screw 405 threadedly inserted in the middle part of the side connecting block 404, the end part of the adjusting screw 405 rotatably connected with the side fixing plate 403, two limiting plug rods 406 symmetrically provided on the two sides of the side fixing plate 403, the end part of the limiting plug rod 406 penetrating through the side connecting block 404, a synthetic leather fixing groove 407 formed on the side of the side fixing plate 403, two resisting screws 408 symmetrically threadedly inserted on the two sides of the end part of the side fixing plate 403, and a fixed resisting piece 409 rotatably connected at the bottom end of the resisting screw 408.

[0030] The middle part of the top end of the punching support table 1 is provided with a top driving groove 410, and the upper feeding screw 411 is rotatably arranged in the top driving groove 410. The side of the punching support table 1 is provided with a servo motor 412, the driving end of the servo motor 412 is fixedly connected with the upper feeding screw 411, the upper feeding screw 411 is sleeved with a driving screw sleeve 413, the top end of the driving screw sleeve 413 is fixedly connected with the bottom end of the synthetic leather supporting plate 401, and two upper feeding grooves 414 are symmetrically arranged on the two sides of the top driving groove 410. The two connecting sliding blocks 415 are slidably arranged in the upper feeding grooves 414, and the top end of the connecting sliding block 415 is connected with the bottom end of the synthetic leather supporting plate 401.

[0031] Embodiment two: the difference between this embodiment and embodiment one is that the bottom end of the driving screw 302 is provided with a baffle.

[0032] So that the driving screw 302 drives the driving connecting seat 304 to move up and down without falling off.

[0033] Embodiment three: the difference between this embodiment and embodiment one is that the bottom end surface of the fixed abutting piece 409 is provided with anti-skid lines.

[0034] So that the fixed abutting piece 409 abuts against and fixes the side edge of the synthetic leather more stably.

[0035] Embodiment four: the difference between this embodiment and embodiment one is that the longitudinal section of the driving screw sleeve 413 and the top driving groove 410 is rectangular.

[0036] So that the driving screw sleeve 413 translates more stably in the top driving groove 410 with the rotation of the upper feeding screw 411.

[0037] In this embodiment, because the existing fiber synthetic leather material automatic punching device is relatively simple in feeding and fixing the synthetic leather during actual use, does not have a tightness adjusting function, so that the synthetic leather is prone to relaxation during punching processing, and needs to be repeatedly disassembled and fixed, which is complicated to operate, affects the accuracy of hole punching, and is not convenient for users to use.

[0038] In summary, when the user needs to punch the fiber synthetic leather small material, the user first needs to place the synthetic leather of appropriate size on the top end of the punching support plate 402 in the feeding adjusting assembly 4, and because the top end surface of the punching support plate 402 and the bottom wall of the synthetic leather fixing groove 407 are located on the same horizontal plane, the side edge of the synthetic leather can be inserted into the synthetic leather fixing groove 407, and the user can rotate the abutting screw 408 at this time.

[0039] The user can also rotate the adjusting screw 405 inserted in the side connecting block 404 to make the adjusting screw 405 pull the side fixing plate 403 of the fixed synthetic leather to move to both sides, so that the tension of the fixed synthetic leather is effectively adjusted, and the tight state is maintained, thereby facilitating the subsequent accurate punching operation.

[0040] When the synthetic leather is fixed, the servo motor 412 is started to drive the feeding screw 411 to rotate, so that the driving screw sleeve 413 can slide in the top driving groove 410, thereby driving the synthetic leather support plate 401 connected to the top end of the driving screw sleeve 413 to move towards the bottom of the puncher 305, and the puncher 305 is used to punch the synthetic leather. This process greatly reduces the participation of manual feeding, improves the safety of workers during operation, and can quickly adjust the tension of the synthetic leather to a tight state when the synthetic leather is loose. It does not need to repeatedly disassemble and assemble the synthetic leather back and forth, and the operation is convenient. The punching accuracy and punching operation efficiency of the synthetic leather are greatly improved.
