[0002] Tissue paper is a common type of paper used in daily life, and is named for its convenience in extraction. Tissue paper needs to be cut into equal-distance segments during the processing process, such as a tissue paper processing cutter with application number CN202420287483.7. The patent changes the patent by starting the servo motor to drive the screw rod located in the slider to rotate, which can drive the two sets of sliders located in the slide to move relative to each other. At the same time, the guide plates at the bottom of the slider will also move synchronously. At this time, the spacing between the two sets of guide plates can be adjusted so that the spacing between the guide plates can be adjusted according to the paper size, ensuring that papers of different sizes can move stably on the conveyor, avoiding the tilt of the paper during cutting that affects the cutting quality, greatly improving the applicability, and the adjustment method is simple and convenient. However, the cutting efficiency of tissue paper is insufficient, and only one section can be cut out each time. In order to solve the above problem, the present invention proposes a tissue paper cutting device. Utility Model Content
