Vacuum die-free forming sole pressing machine and using method thereof

Abstract

The invention relates to the field of shoemaking equipment, in particular to a vacuum die-free forming sole pressing machine and a using method thereof, and is characterized in that the vacuum die-free forming sole pressing machine comprises an upper rack, a pressing driving mechanism, a side pressurizing mechanism, a pressing assembly, a vacuum assembly, a lifting mechanism and a clamping mechanism; the vacuum assembly is fixed to the bottom of the upper rack, the pressing assembly is located over the vacuum assembly, the pressing assembly is driven by the pressing driving mechanism to be attached to or away from the vacuum assembly, and the side edge pressurizing mechanism is connected with the upper rack, the pressing driving mechanism and the pressing assembly in a pivoted mode. According to the vacuum die-free forming sole pressing machine, the pressing assembly and the vacuum assembly can be tightly matched, and the sealing performance and the pressing effect are improved; the shoe tree and the shoe body are positioned and fixed in all directions through the clamping mechanism, and the shoe sole and the vamp are prevented from deviating in the pressing process; the mode of combining hydraulic positioning and vacuumizing positioning is adopted, the operation steps are simple, positioning is accurate, and meanwhile the pressing speed is increased.

Description

Technical field [0001] The invention relates to the field of shoemaking equipment, in particular to a vacuum mouldless forming sole press and a method of use thereof. Background technique [0002] After the raw materials are cut, stitched, and stretched, they have the embryonic form of the shoe. After the upper is glued, it can become a shoe. The bonding of the upper sole is the process of bonding the outsole and the upper foot and the inner sole of the stretched upper with an adhesive. The process of combining the upper sole is a major process in the shoemaking process. The methods of combining the upper sole include There are many types. Gluing, vulcanization, molding, injection, and seam are the five basic processes. Among them, the viscose process is the most commonly used on the market. The pressing machine is the abbreviation of viscose pressing machine. The traditional pressing machine is divided into pneumatic pressing machine and hydraulic pressing machine. In order to ...

AI Technical Summary

Problems solved by technology

Pressing machine is the abbreviation of viscose pressing machine. The traditional pressing machine is divided into pneumatic pressing machine and hydraulic pressing machine. The lower part is attached to the vacuum component. The existing method of closing the upper pressure component only through the hydraulic cylinder. Since the upper pressure component is rectangular, the two ends in the long direction are prone to air leakage due to insufficient pressurization, which affects the seal. Sex, which in turn affects the pressing of the sole

In order to form the positioning of the sole and the upper before pressing and prevent the sole from running off during pressing, the sole, upper and shoe last need to be clamped and fixed before pressing. The existing manual fixing method is often used, which is inconvenient to operate. Inefficient and poorly positioned

In addition, in order to form a pre-positioning of the sole and the upper before pressing and prevent the sole from wandering during one pressing, the prior art solves this by setting up two-stage airbags, the first-stage airbag covers the sole under the action of air pressure, and the second-stage The airbag is further pressurized under the action of air pressure. Although the existing technology can solve the problem of sole pre-positioning, there are still the following problems: two pressurized air ports need to be set on the upper pressure cylinder, and the structure and control are relatively complicated; Multiple steps such as vacuuming, first-stage airbag pressurization, and second-stage airbag pressurization are complicated to operate, and the operation time is long, which affects production efficiency; there is no sealing structure between the airbag and the cylinder, and the sealing is poor, resulting in air leakage and increasing energy consumption. At the same time, the production efficiency is reduced; the airbag is inconvenient to disassemble and replace as a wearing part; due to the strong compressibility of the gas, the pressurization speed is relatively slow.
