[0021] Reference Figure 6 The internal thread gear seat 8 includes an external tooth lower seat body 80. A drive ring tooth 81 is fixedly installed in the middle of the outer side of the external tooth lower seat body 80.

The external thread adjustment rod 61 is located inside the adjustment internal thread hole 84 for adaptation and screw connection. The drive ring tooth 81 is adapted to mesh with the drive gear 77.

[0022] Using the above solution: the stepper motor 76 drives the drive gear 77 to rotate, which in turn drives the internal threaded gear seat 8, which meshes with it, to rotate within the U-shaped mounting frame 75. At this time, the position of the pressing frame 6 within the lifting frame 5 can be adjusted by the external threaded adjusting rod 61, which is screwed to the internal threaded gear seat 8. This adjusts the extension of the buffer elastic element 54, thereby adjusting the buffer elastic force when the rotating material roller 65 presses down and contacts the fabric. This allows for adjustment of the buffer force to suit different fabric materials, ensuring appropriate force during material feeding.

[0023] The working principle of this utility model is as follows: During use, the leather shoe fabric is placed on the concave curved edge table 12. At this time, the PLC control device controls four sets of identical electric telescopic cylinders 57 to drive four sets of electric cylinder telescopic rods 58 to extend and retract, pressing two sets of rotating material rollers 65 against both ends of the fabric. The cushioning elastic element 54 provides buffering, ensuring a certain degree of adhesion during pressing. Then, by controlling two sets of stepper motors 63 to drive the two sets of rotating material rollers 65 to rotate outwards in opposite directions, the fabric can be quickly stretched and flattened. The fabric can then be cut using the cutting head frame 3 and the cutting head 4 with cutting blades. After cutting, the two sets of rotating material rollers 65 are controlled... 5. With the fabric rotating in the same direction, it can be quickly fed out and fall through the side arc surface of the concave arc edge table 12. During the cutting process, the stepper motor 76 drives the drive gear 77 to rotate, which in turn drives the internal thread tooth seat 8, which meshes with it, to rotate within the U-shaped mounting frame 75. At this time, the position of the pressing frame 6 within the lifting frame 5 can be adjusted by the external thread adjusting rod 61, which is screwed to the internal thread tooth seat 8. This adjusts the extension of the buffer elastic element 54, thereby adjusting the buffer elastic force when the rotating material roller 65 contacts the fabric during the downward press. This allows for adjustment of the buffer force to adapt to different fabric materials, ensuring that the force is appropriate when feeding the material.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
