Description

Technical Field

[0001] The utility model belongs to the field of shoe production equipment, and particularly relates to a shoe upper flattening device. Background Art

[0002] In the shoemaking process, after automatic polishing and gluing, the connection position of the upper parts will be warped, which affects the fit between the upper and the sole. Therefore, the upper needs to be hammered flat to ensure reliable fit between the upper and the sole. As we all know, the connection between the upper and the sole is an irregular surface. If a general clamping mechanism is used for clamping and hammering, due to uneven force, there will be new warping at the place with slight force. Therefore, it is impossible to use a general clamping mechanism for clamping and hammering. Therefore, manual hammering is mostly used at present, which has low production efficiency, is not conducive to mechanized and fully automatic production, and hinders the promotion of large-scale production.
