Description

Knife gate structure and tobacco leaf filament cutter Technical Field The utility model relates to the technical field of tobacco processing equipment, in particular to a cutter door structure and a tobacco cutter. Background When the tobacco cutting machine is used, the tobacco leaves are cut into cut tobacco with a specified width through the processing of the tobacco cutting machine, so that the physical shape of the tobacco leaves is changed, and the tobacco leaves are convenient to process and produce cigarettes. At present, a tobacco cutter adopting horizontal feeding comprises a conveying chain, a cutter gate and a tobacco cutter roller, tobacco leaves form tobacco cakes under the compaction action of the conveying chain and are conveyed to the cutter gate, the cutter gate encloses a discharge hole, and the tobacco cakes are cut by the tobacco cutter roller to form tobacco shreds after extending out of the discharge hole. Compared with a common vertical feeding mode, the tobacco cake is conveyed to the cutter gate in the horizontal feeding mode approximately along the horizontal direction, so that the tobacco cake is not easy to compact under the pressure of the upper cutter gate and the lower cutter gate, tobacco leaves cannot be cut uniformly in the shredding process, and the problem of sheet running of the shredder is caused. Disclosure of utility model The utility model aims to provide a knife gate structure and a tobacco leaf shredder, which can solve the problems that a horizontal feeding mode cannot cut uniformly and run a piece.
