The invention relates to a device for pressing expanded tobacco stems into pieces and belongs to the technical field of tobacco manufacturing. The device comprises a
machine frame (1), a fixed roller (2), an upper movable roller (3), a lower movable roller (4), a fixed roller scraper (5), a fixed roller lubricating
system (6), an upper movable roller lubricating
system (7), an upper movable roller scraper (8), a lower movable roller lubricating
system (9), a lower movable roller scraper (10), a first pressing gap adjustment device (11), a second pressing gap adjustment device (12), an upper movable roller hydraulic system (13), a lower movable roller hydraulic system (14), a stem sorting device (15) and a stem piece arrangement device (16). According to the device, piece pressing can be conducted on expanded tobacco stems twice continuously; the thickness of pieces obtained through pressing reaches 0.2-0.4 mm; the shapes of the pieces are good, and
cut stems are completely consistent with tobacco shreds in shape; the
utilization rate of the expanded tobacco stems can be effectively increased, and the areas occupied for storing the expanded tobacco stems and the
transportation cost of the expanded tobacco stems are reduced.
