Technical Field

The invention belongs to the field of tobacco production equipment, and particularly relates to a secondary tobacco block slitting treatment device and method.

Background

In a tobacco production line, a tobacco flake loosening and conditioning machine is key equipment in a tobacco shred production line and has the functions of loosening raw material tobacco blocks so as to increase the moisture content and temperature of tobacco flakes, improve the processing resistance of the tobacco flakes, improve the sensory quality of the tobacco flakes and meet the production process requirements of subsequent shred production procedures. And because the raw material size is bigger, the production line mostly adopts the vertical slicer to process the tobacco block before the loosening and moisture regaining equipment, and vertically cuts the tobacco block according to the set cutting thickness along the height direction of the tobacco block, so that the tobacco sheet is easy to loosen in the loosening and moisture regaining machine, and fully absorbs moisture and temperature. However, in the actual production process, the phenomena of tobacco cake concentration and large volume in the materials subjected to loosening and moisture regaining still exist, particularly, when the tobacco leaves with higher production formula grades are produced, the tobacco leaves have high oiliness and long storage time, the adhesion among tobacco flakes is serious, the treatment effect of the loosening and moisture regaining machine is directly influenced, and the treatment effect of the subsequent tobacco making process is reduced.

At present, sorting machines are arranged behind a loosening and conditioning machine for processing tobacco cakes in part of enterprises, but due to the fact that the size of an inlet is limited, the situation of material blockage is easy to happen, and equipment is stopped; the manual picking method adopted by some enterprises is high in labor intensity and poor in controllability; some enterprises also adopt local winnowing equipment to remove the tobacco cakes and then carry out manual tearing treatment, so that the manual intervention degree is high, and the uniformity of material properties is poor; some enterprises improve the structural form of the raking nails and the shoveling plates in the loosening and conditioning machine, but the improvement range of the treatment effect is not obvious. Tracking observation shows that although the sliced tobacco blocks are closely arranged on the slicing discharge conveyor belt and the conveying flow is controlled by the electronic scale, the sliced tobacco blocks have the conditions of unstable block size and continuous dumping when being output from the electronic scale, so that the flow at the outlet of the electronic scale cannot be maintained, and the materials in the state have the problems of uneven heating of the core and the surface, insufficient indirect water and steam adding amount and large fragmentation rate after entering the loosening and conditioning machine.

In view of the above, it is necessary to develop a device that can reduce the size of the tobacco mass entering the loosening and conditioning machine and stabilize the feeding flow.
