Die cutting machine usually includes a frame and a die cutting knife group arranged on the frame. The die cutting knife group includes an upper knife frame and a lower knife frame. There are several blades on the upper and lower knife frames for efficient cutting of battery cells. In the process of cutting battery cells, due to the shape and size of battery cells, the shape and size of battery cells are often cut. Small has different needs, so it is also necessary to adjust the gap between each blade on the upper knife holder and the lower knife holder by installing and removing gaskets to meet the cutting needs. However, when adjusting the blade gap of the above-mentioned die-cutting knife group, the upper knife holder or the lower knife holder needs to be pulled out and the gasket needs to be installed.
