The utility model discloses a cutting and cloth pressing mechanism for a pocket opening machine, which comprises a base component, an external pressing component and an internal pressing component, both the external pressing component and the internal pressing component are fixed on the base component, the external pressing component can realize the functions of opening, folding and pressing pocket cloth, and the internal pressing component can realize the fixation of the pocket cloth and cloth to be sewn. A first limiting assembly and a second limiting assembly in the outer pressing assembly are matched with a third limiting assembly to be meshed and driven by a gear and a rack, the position of a bag opening of a cloth bag is adjusted, and therefore the width and the length of the bag opening are set to be changed, and a modularized pressing block in the inner pressing assembly is formed by combining a plurality of different pressing blocks. Various shapes can be formed according to requirements, the quick switching requirements of multi-specification bag openings are met, and the production efficiency is improved.

The application discloses a lining feeding device and a use method thereof, which comprises a lining feeding frame, a punching die and a punching cutter corresponding to the punching die are arranged on the lining feeding frame, a push plate connected with a transmission belt and capable of being driven to reciprocate is arranged above the punching die, a feeding roller is drivingly connected to the transmission belt, and a driven roller is installed on the lining feeding frame and is in clutch transmission cooperation with the feeding roller. The push plate and the feeding roller are driven by the shared transmission belt, so that the installation of the driving part is reduced, the structure of the equipment is more compact, meanwhile, the lining cloth is automatically pushed to a sewing station by the push plate, automatic, efficient and accurate feeding of the lining cloth is realized, and the subsequent sewing quality of the lining cloth is ensured.
