Description

Technical Field

[0001] The utility model relates to the field of massage chair processing, in particular to an automatic leather punching device. Background Art

[0002] Most of the exteriors of massage chairs are made of leather products. In order to increase the air permeability of the leather, when processing massage chairs, it is necessary to punch holes in the leather. When punching holes, since the leather is relatively soft, it is inconvenient to position the leather, which easily causes the leather to be misaligned, reducing the punching accuracy and affecting the processing quality. A multi-position punching device for massage chairs with the application number 202321709694.7 can solve the problem that the leather is not easy to position. Since the leather is relatively soft, it is necessary to stretch the leather when punching holes, so it is necessary to position the leather, which is rather troublesome, so the punching of the leather will be uneven. In order to solve the punching problem of the leather, the inventor has invented an automatic leather punching device to solve the punching problem of the leather of the massage chair.
