Shoe sole positioning device

Abstract

The invention provides a shoe sole positioning device. The shoe sole positioning device comprises a first push element, a U-shaped frame, pressing mechanisms and a base block which are sequentially connected from top to bottom, a groove is formed in the bottom face of the base block, and vacuum openings are formed in the bottom of the groove; a pushing end of the first push element faces downwards, and a push rod of the first push element drives the U-shaped frame to move up and down; each pressing mechanisms comprise a second push element and a first push rod, the second push elements are installed on the U-shaped frame, and the first push rods are installed on push rods of the second push elements; the base block is provided with guide holes for moving of the first push rods, the guide holes run through the bottom of the groove, and the first push rods are arranged in the corresponding guide holes. In the shoe sole positioning device, the shoe sole is positioned through the groove inthe bottom face of the base block, the shoe sole is adsorbed to be fixed through the vacuum openings, the shoe sole is pressed on a shoe tree through the pressing mechanisms, and then, it is achievedthat a shoe upper is closely stuck to the shoe sole.

Description

technical field [0001] The invention belongs to the field of shoe-making production, and in particular relates to a shoe sole positioning device. Background technique [0002] In the production of shoes, when the sole and upper are assembled, the sole is placed flat on the workbench, and then the sole and the upper fitted on the last are matched manually, and the sole and upper are bonded by pressing down the last. This assembly method The sole and the upper are tightly fitted by pressing down on the shoe last. Since the upper is set on the shoe last, the structure of the pressing device for shoe last pressing is relatively complicated, and the bonding surface of the shoe last and the sole is sometimes an arc structure. Therefore, the shoe last It is difficult for the whole pressing device of the last to realize the tight fit of the upper and the sole, which causes the upper and the sole to be glued reasonably and unevenly, and then the local easy-to-open glue phenomenon occ...

Therefore, the shoe last It is difficult for the overall pressing device of the last to achieve a tight fit between the upper and the sole, resulting in a reasonable and uneven fit between the upper and the sole, which in turn leads to the occurrence of local easy-to-open glue
