Tab cutting device

Abstract

The application provides a tab cutting device, which comprises a driving mechanism, an upper knife seat, an upper cutting knife, a lower knife seat, a lower cutting knife and at least two adjusting blocks, wherein the upper cutting knife is installed on the upper knife seat through a first mounting seat, the lower cutting knife is fixedly installed on the lower knife seat and is arranged in a staggered manner with the upper cutting knife, and the position of the first mounting seat is adjustable; the first end of each adjusting block is installed on the first mounting seat in parallel with the upper cutting knife, each adjusting block has a first reference surface corresponding to the cutting surface of the upper cutting knife and a second reference surface abutting against the cutting surface of the lower cutting knife, and the first reference surface and the second reference surface are coplanar; and the driving mechanism is used for driving the upper cutting knife to ascend and descend. By adjusting the second reference surface of the adjusting block to be coplanar with the cutting surface of the lower cutting knife, the relative position relationship between the upper cutting knife and the lower cutting knife can be ensured. When the upper cutting knife is replaced, the relative position between the new upper cutting knife and the lower cutting knife can be ensured without re-adjusting the first mounting seat, so that the debugging efficiency of the tab cutting device is improved.
