Description

Technical Field

[0001] The utility model relates to a positioning and fixing structure for a shoe pressing machine. Background Art

[0002] In the process of shoemaking, glue is usually used to bond multiple layers of soles, such as bonding the outsole that contacts the ground and the midsole that is located on the outsole. The process of bonding the outsole and the midsole is called bonding in the industry. Glue is also used to bond the sole and the upper. The process of bonding the sole and the upper is called molding in the industry. In addition, some shoes require additional materials, such as rubber, to be glued to the toe or other parts to increase the functional effects of the shoe body. In the above gluing process, pressure needs to be applied to the bonding parts to ensure the firmness of the bonding. The traditional shoemaking process is manual pressing, which is inefficient and difficult to ensure consistency in processing quality.

[0003] The shoe press machines with a high degree of automation used in the prior art are, to a certain extent, effective, but also have certain problems: in the automated production line, the shoe is generally put on the shoe base, and the shoe base is conveyed to the shoe press through a conveyor line. Workers or other equipment place the shoe base on the fixed structure of the shoe press, and the shoe press then performs shoe pressing operations on the shoe on the shoe base. However, the shoe base and the fixed structure of the shoe press are not stable, resulting in inaccurate relative positioning between the upper and the sole. During the downward pressing process of the shoe press, the positioning deviation will cause the force position to change, causing the shoe base to shift, resulting in shoe pressing failure, making it difficult to ensure the product qualification rate. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and provide a positioning and fixing structure for a shoe press machine.

[0005] In order to solve the above technical problems, the utility model provides a positioning and fixing structure for a shoe press machine, comprising a sliding guide rail, a shoe base, a positioning and locking mechanism, and a hanging mechanism;

[0010] The shoe press is used to move upward to correspond to the shoe base suspended on the suspension mechanism.

[0011] In a more preferred embodiment, the first positioning sliding component includes two sliding protrusions, and the second positioning sliding component includes two sliding recesses, the two sliding recesses are arranged on both sides of the positioning base, and the sliding recesses slide correspondingly on the sliding protrusions.

[0035] The second positioning sliding component slides on the first positioning sliding component. When the positioning base 222 slides to the working position, the sliding between the second positioning sliding component and the first positioning sliding component is limited by the locking position of the positioning column 231 and the positioning hole 2223.
