The structure of the shredder includes a feeding device, an upper copper chain, a lower copper chain, a knife roller and a discharge hopper. The feeding device conveys the tobacco sheets between the upper copper chain and the lower copper chain. The tobacco sheets are compacted by the upper copper chain and the lower copper chain and then output from the knife gate. Under the rapid rotation of the knife roller, the shredder installed on the knife roller cuts the tobacco sheets into shredded tobacco that meets the process quality requirements. After the shredded tobacco is separated by the rotating cutter of the knife roller, it is quickly discharged from the discharge hopper in rows along a certain motion trajectory under the action of centrifugal force. In the above process, a large number of strips and shreds will be formed, which will bring a series of problems to the subsequent processing.
