Secondary slitting treatment device and method for tobacco block

Abstract

The invention discloses a secondary slitting processing device for a tobacco block. The secondary slitting processing device comprises a rack, stripping mechanisms, a slicing mechanism and a separation aiding mechanism, wherein the stripping mechanisms are connected to the two ends of the rack and can slide in a tobacco block discharging direction; the slicing mechanism is fixed to the stripping mechanism and comprises a cutter, and the cutter can move in a direction perpendicular to the tobacco block discharging direction and can rotate and swing; and the separation aiding mechanism is fixed to the upper middle portion of the rack and comprises an auxiliary separation piece capable of moving up and down. The invention further discloses a treatment method of the device. According to the invention, tobacco blocks vertically slit by the slicing machine can be subjected to sheet-shaped single block decomposition again so as to improve the treatment effect of a next procedure; meanwhile, metered conveying flow can not be influenced so as to realize continuous production, and feeding flow is stabilized so as to uniformize the properties of materials to be treated by the next procedure; and the device has fault-tolerant capability and can adapt to the accidental material state change of upstream equipment, the possibility of breakage of tobacco leaves in a processing process is small since the chance that the tobacco leaves are cut off is small, the integrality of the device is high, and the device is convenient to install.

Description

technical field [0001] The invention belongs to the field of tobacco production equipment, and more particularly relates to a device and method for secondary cutting and processing of cigarette blocks. Background technique [0002] In the tobacco production line, the tobacco flake loosening and dampening machine is the key equipment in the tobacco shred production line. The sensory quality of the tobacco sheet meets the production process requirements of the subsequent silk-making process. Due to the large size of the raw material, the production line usually uses a vertical slicer to process the cigarette blocks before the loosening and rehydration equipment, and vertically cuts the cigarette blocks according to the set cutting thickness along the height direction of the cigarette blocks, so that the tobacco sheets are easy to loose in the loosening and rehydration machine. And fully absorb moisture and temperature. However, in the actual production process, there will st...

Problems solved by technology

However, in the actual production process, there will still be the phenomenon of concentrated tobacco cakes and large volumes in the materials after loosening and moisture resurgence, especially when producing tobacco leaves with high formula grades, the tobacco leaves are oily and stored for a long time. The bonding between them is relatively serious, which directly affects the treatment effect of the loose moisture regainer and reduces the treatment effect of the subsequent silk making process.

[0003] At present, some enterprises have set up sorting machines to process the smoke cakes after loosening the dampening machine, but due to the limited size of the entrance, material blockages are prone to occur, resulting in equipment shutdown; while some enterprises use manual sorting methods, which are labor-intensive , poor controllability; there are also some enterprises that use on-site winnowing equipment to remove the tobacco cakes and then manually tear them, the degree of manual intervention is high, and the uniformity of material properties becomes poor; The structural form of the nail and copy board is improved, but the improvement of the processing effect is not obvious

Through follow-up observation, it is found that although the sliced ​​cigarette blocks are closely arranged on the slice discharge conveyor belt and the conveying flow is controlled by the electronic scale, the sliced ​​cigarette blocks are output from the electronic scale due to unstable block size and implicated dumping. In such a situation, the flow rate at the outlet of the electronic scale cannot be maintained. After entering the loose moisture conditioner, the material in this state has the problems of uneven heating of the center and surface, insufficient indirect water and steam addition, and high crushing rate.
