Cutting process of synthetic leather for shoes

Abstract

The invention discloses a cutting process of synthetic leather for shoes. The process comprises the following steps that several roll materials are placed on a material unwinding frame, then flat laidon a cutting die holder, and then wound around a winding frame, then a servo motor is started to drive a gland to press downwards, synthetic leather on the cutting die holder is cut into instep and toe cap materials, and then taken out and placed, then a winding motor is started to wind cut synthetic leather, an unwinding motor is started at the same time to release the roll materials, a non-cutsynthetic leather section is flat laid on the cutting die holder, and cutting is continuously performed according to the above steps. According to the process, the unwinding motor in the unwinding mechanism is started to synchronously drive the synthetic leather to extend, then is flat laid on an arranged cutting table and then wound around the arranged winding frame, therefore layer-by-layer synthetic leather is leveled on the cutting table to be integrally cut into the instep and toe cap materials through an instep cutter and a toe cap cutter, by means of the equipment, material laying and material winding are conducted in order, and acceleration of manufacturing and centralized management of residual materials are facilitated.

Description

technical field [0001] The invention relates to the technical field of shoe processing, in particular to a process for cutting synthetic leather materials for shoes. Background technique [0002] Synthetic leather is a plastic product that mimics the composition and structure of natural leather. It has a certain degree of air permeability and is closer to natural leather than ordinary artificial leather. Widely used in making shoes, boots, bags and ball games. Footwear processing is to sew the cut vamp and toe cap synthetic leather into a whole according to the design structure, and then glue the bottom of the shoe to the sole through injection molding. When cutting synthetic leather, the designed drawings are laid flat on the layered synthetic leather materials and fixed, and then the cloth cutting machine is manually pushed along the drawings to cut. The cutting preparation work is complicated and the cutting The leftover materials are piled up messily, which is inconve...

AI Technical Summary

Problems solved by technology

When cutting synthetic leather, the designed drawings are laid flat on the layered synthetic leather materials and fixed, and then the cloth cutting machine is manually pushed along the drawings to cut. The cutting preparation work is complicated and the cutting The leftover materials are piled up messily, which is inconvenient for centralized management. Care should be taken when handling the cut uppers and toe materials to avoid confusion, which affects the progress of shoe production as a whole.
