Sole adhesion method

Abstract

The invention relates to a sole adhesion method. The sole adhesion method comprises a preparation step, a sealing step, a pressurizing step and a taking-out step, the preparation method comprises thefollowing steps: putting a shoe tree into a semi-finished shoe product formed by combining a vamp and a midsole; coating the bottom surface and the sole of the semi-finished product of the shoe with colloid and combining to form the shoe; in the sealing step, shoes are placed in a sealed bag body; air in the sealed bag body is pumped out; the shoe sole and the shoe edge between the sealing bag body and the shoe tree are extruded to the bottom of the semi-finished shoe product through vacuum pressure; in the pressurizing step, the sealing bag body is further extruded in a forward pressure barrel through internal pressure, the shoe sole and the shoe edge are further attached and extruded to the bottom of the shoe semi-finished product, in the taking-out step, the forward pressure barrel is decompressed, the sealing bag body is opened under the atmospheric pressure, and the shoe is taken out; therefore, the shoe sole and the shoe edge can be prevented from deforming in the adhesion process, and the production cost can be further reduced.

Description

Technical field [0001] The invention relates to a sole adhesion method, in particular to a sole adhesion method through a vacuum sealed bag. Background technique [0002] The existing shoe sole adhesion method uses a shoe-sticking machine using glue as the adhesive material to directly squeeze the shoe sole and the edge of the shoe and the bottom surface of the shoe semi-finished product with rigid mechanical force to bond the shoe. It is targeted for different shoes and different sizes. For shoes, the shoe sticking machine needs to adjust the pressing pressure of the rolling wheel and the path of the rolling wheel according to the shoe type and size, which not only causes trouble and inconvenience during the operation, but also affects ordinary small and medium-sized enterprises. In other words, the shoe sticking machine is a high unit price production equipment, which in turn causes the production cost of producing footwear to increase. [0003] Furthermore, the shoe-sticking ma...

Problems solved by technology

[0004] In order to solve the existing method of sticking soles, through shoe sticking presses, the lack and insufficiency of the deformation of the sole and the edge of the shoe are caused. The purpose of the present invention is to propose a method of sticking soles. The semi-finished shoe is placed in a sealed bag together with the sole coated with the heated colloid, and the air in the sealed bag is drawn out to present a negative pressure vacuum state, and the sealed bag is pushed toward the semi-finished shoe and the semi-finished shoe through the vacuum negative pressure. The direction of the sole shrinks, so that the sole and the edge of the shoe are tightly squeezed on the bottom of the semi-finished shoe, and then the sealed bag is further squeezed by air through pressure adjustment in the positive pressure barrel, so that the sole and the edge of the shoe Further sticking and extruding on the bottom of the semi-finished shoe, the present invention can prevent the deformation between the sole, the edge of the shoe and the upper, and reduce the production cost
