Edge cutting device

According to the edge cutting device, a circular knife blade is adopted, an adjusting mechanism and a driving device are arranged, and guide rollers on the two sides of a circular knife are adjusted to proper positions through the adjusting mechanism, so that a sheet can well pass through a cutting edge, the flatness is guaranteed, and the edge cutting effect can be guaranteed; by shaking the hand wheel and rotating the screw rod, the knife edge width of the circular knives on the two sides is consistent with the actual required width of a produced finished product; due to the fact that the rotating speeds of the circular knife blades corresponding to different production speeds are different, the rotating speeds of the circular knife blades need to be adjusted to be matched with the production speeds at the moment, the rotating speeds of the circular knife blades are adjustable by matching with a motor capable of adjusting the rotating speeds, the edge cutting effect is further guaranteed, and by means of th
