Three-dimensional mould with lifting degree for sewing shoes and boots and sewing method for pressing toe part on heel part

Abstract

The invention provides a three-dimensional mould with lifting degree for sewing shoes and boots and a sewing method for pressing a toe part on a heel part. The three-dimensional mould comprises a bottom plate, a heel part limiting plate, a toe part limiting plate, a toe part pressing plate and a heel part three-dimensional separation pressing plate; a thread groove is formed in the bottom plate; the heel part three-dimensional separation pressing plate forms the lifting degree; the bottom plate, the heel part limiting plate, the toe part limiting plate, the toe part pressing plate and the heelpart three-dimensional separation pressing plate are arranged from the bottom up in sequence, and the middle parts of the bottom plate, the heel part limiting plate, the toe part limiting plate, thetoe part pressing plate and the heel part three-dimensional separation pressing plate expose the thread groove; the heel part limiting plate is fixedly connected with the bottom plate; the toe part limiting plate is connected with the left side of the heel part limiting plate; the toe part pressing plate is hinged with the left side of the toe part limiting plate; and the heel part three-dimensional separation pressing plate is hinged with the right side of the heel part limiting plate. The technology that a computerized pattern sewing machine can only sew a plane is broken through, and the production efficiency is greatly improved while the product sewing problem is solved; and during sewing, operation can be carried out only by putting a material piece into a designated position, operation can be carried out by an operator who is not familiar with the sewing machine, long-time training is not needed, and the production skill level of the vast number of staff is further improved.

Description

technical field [0001] The invention belongs to the technical field of shoe-making sewing, and in particular relates to a three-dimensional mold with sway for sewing shoes and boots and a method for sewing a front upper and a rear upper. Background technique [0002] When the front of the shoe is pressed against the back of the shoe, because the back has been formed, it is not in a flat structure, and there is still a sway, so it is impossible to use intelligent automation equipment. It can only be operated manually by a sewing machine, but when sewing curved When the position is large, the sewing effect cannot meet the requirements of the process, and an operator with sewing experience must be required to sew, and the work efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a three-dimensional mold with sway for sewing shoes and boots, so as to overcome the above-mentioned technical problems in the prior art. [0004] A...

Problems solved by technology

[0002] When the front of the shoe is pressed against the back of the shoe, because the back has been formed, it is not in a flat structure, and there is still a sway, so it is impossible to use intelligent automation equipment. It can only be operated manually by a sewing machine, but when sewing curved When the camber is large, the sewing effect cannot meet the requirements of the process, and an operator with sewing experience must be required to sew, and the work efficiency is low.
