Shoe sole pressing device

Abstract

The invention relates to a shoe sole pressing device which comprises a rotating disc conveying mechanism and a plurality of shoe sole pressing machines. Each shoe sole pressing machine comprises a machine frame and a double-air-bag pressing device which comprises a shoe fixing seat, a shoe sole pressing mechanism and a locking mechanism. Each shoe sole pressing mechanism comprises an outer cover, a first rubber sleeve and a second rubber sleeve, the first rubber sleeve is arranged at the opening position of the outer cover and is recessed inwards, the second rubber sleeve is arranged in the middle portion of the inner wall of the outer cover, the outer cover is divided into an upper cavity and a lower cavity which are airtight through the first rubber sleeve and the second rubber sleeve, and an upper vent and a lower vent are formed in the outer cover. Due to the fact that first air bags completely and closely wrap a shoe sole and the periphery of the shoe sole, pressing is achieved through air pressure, the shoe sole and the periphery of the shoe sole are even in stress, the bonding effects of all portions are consistent, the shoe sole and the periphery of the shoe sole are further pressed through downward extruding of the second rubber sleeves, bonding of the shoe sole and the periphery of the shoe sole is firmer, and shoe quality is improved.

Description

technical field [0001] The invention relates to a shoe-making device, in particular to a shoe sole pressing device. Background technique [0002] In the manufacturing process of shoes, it is necessary to bond the upper and the sole. In the process of bonding, an external force is required to attach the parts that have been glued and need to be bonded to each other and apply a certain pressure. The sole pressing machine is to implement the above Process machinery. [0003] The sole pressing device is the main working part of the sole pressing machine. The sole pressing machine generally includes a sole pressing device, a working platform and a rubber mold. The rubber mold similar to the shape of the sole is placed on the working platform, and the leather shoes that have been glued are placed in the rubber mold, and the inside of the leather shoes is used for support. Inner last. The shoe sole pressing device is located on the working platform and includes a hydraulic cylin...

AI Technical Summary

Problems solved by technology

[0007] Obviously, the air bag in the above-mentioned fast shoe upper and sole pressing machine only plays the role of auxiliary pressing, and the pressing effect it plays is also only aimed at the bottom surface of the sole, and cannot solve the two problems between the toe and the heel of the front and rear of the shoes. The problem that the bonding effect of the arc position on the side is weaker than other places

[0008] In addition, since the glue needs to wait for the solidification of the sole, it takes a long time to wait for pressing. The production efficiency of the above-mentioned fast shoe upper and sole pressing machine is obviously low, and it is difficult to meet the needs of automated production.
