Wrapper processing system and method

The invention discloses a wrapper processing system and method. The wrapper processing system comprises a first conveyor belt, a slide carriage box, a push-pull device, a second conveyor belt and a controller, wherein a preset angle is formed between the first conveyor belt and a horizontal direction; an inlet of the slide carriage box is formed under the top end of the first conveyor belt, and wrapper cutter knives are arranged at an outlet of the slide carriage box; the push-pull device is connected with a casing of the slide carriage box; the second conveyor belt is positioned under the outlet of the slide carriage box; continuous wrappers are transmitted to the top end through the first conveyor belt, the wrappers flow into the slide carriage box through the inlet and flow out from the outlet to enter into the second conveyor belt, the push-pull device pushes the slide carriage box to do horizontal reciprocating movement so as to enable the wrappers to be folded on the second conveyor belt, the cutter knives cut off the wrappers according to the cut-off instructions of the controller, and the second conveyor belt is used for outputting the cut-off wrappers. Through the manner, the wrappers can be cut and transported fluently and orderly, so that not only is the human cost for processing the wrappers reduced, but also the wrapper processing efficiency is effectively improved.
