This utility model discloses a leather shoe fabric cutting device for leather shoe production and processing, including: a cutting cabinet, a frame rail fixedly installed at one side of the cutting cabinet, a cutting head frame slidably installed at one side of the frame rail, a cutting head slidably installed at one upper end of the cutting head frame, and a lifting frame fixedly installed at one upper end of the cutting cabinet; in this utility model, during the cutting operation, a stepper motor drives the gear to rotate, which in turn drives the internal threaded tooth seat meshing with it to rotate within the U-shaped mounting frame. At this time, the position of the pressing frame within the lifting frame can be adjusted by the external threaded adjusting rod screwed to the internal threaded tooth seat, thereby adjusting the extension of the buffer elastic element. In this way, the buffer elastic force when the rotating material roller presses down and contacts the fabric can be adjusted, thus adapting to different fabric materials to adjust the buffer force and ensuring appropriate force when feeding the material.

The present application provides a kind of film processing system and method.The film processing system includes: first active roller, it is configured to controlled rotation, film strip is driven forward by first active roller via;Second active roller, it is configured to controlled rotation, film strip from the direction of first active roller is driven forward by second active roller via;Stretch detection device, it is configured to detect the distance value between the positioning mark on the film strip between first active roller and second active roller;Controller, it is configured to control the rotational speed of first active roller and second active roller based on the distance value obtained by the stretch detection device, so that the distance value converges to the predetermined distance threshold range.In this way, by controlling the rotational speed of first active roller and second active roller, the stretch of the film strip can be adjusted very accurately.
