Tobacco leaf slitting machine

The utility model discloses a tobacco leaf slitting machine which comprises a machine frame, a belt conveying device and a shearing device which are installed in the machine frame, the belt conveying device conveys tobacco leaves to the shearing device for tobacco leaf shearing, and the tobacco leaf slitting machine further comprises a plurality of tobacco leaf self-adaptive thickness buffering mechanisms which are installed on the machine frame and used for adjusting the belt tensioning degree of the belt conveying device. The device has the advantages that tobacco leaves are extruded up and down through the belt and run at the same speed, displacement of the tobacco leaves is reduced as much as possible in the slitting process, and the sheet type structure is guaranteed; 2, the tobacco leaf self-adaptive thickness buffer mechanism is matched with the belt, so that the effects of flattening, conveying and position stabilizing of tobacco leaves with different thicknesses and tobacco leaves with different part
