As is well known, when purchasing tobacco leaves, raw tobacco is generally sorted according to quality grade, sundries, soil, rotten or variegated tobacco leaves are removed, then the sorted raw tobacco is compacted according to the standard of 50 kg per package to form a standard size, finally, the surfaces of the raw tobacco are sewn by hemp chips to form a rectangular tobacco package, and the rectangular tobacco package is transported to a redrying enterprise for redrying.
In the process of storage and transportation, the quality of raw cigarettes can change to a certain degree due to the influence of factors such as temperature, humidity, stacking extrusion and the like on the cigarette packets. Therefore, the tobacco bale is required to be scattered by redrying enterprises before threshing and redrying, and the compacted raw tobacco is manually scattered and sorted again (deteriorated and rotten tobacco leaves are removed). After sorting is finished, the raw cigarettes with different grades are respectively loaded into corresponding cigarette frames according to the standard of 600 kilograms per frame, and then the tobacco frames are transferred to a threshing and redrying production line for feeding production and processing.
When feeding, raw tobacco with different grades is manually laid on a conveyor belt one by one according to the raw material proportion determined by a threshing and redrying production process, then the stem heads of the raw tobacco are cut by a disc type cutting knife, and tobacco leaves enter the subsequent procedures along with the conveyor belt.
As can be seen from the above process, the current raw cigarette packaging mode has the following defects:
1) The cigarette packet forming can be realized only by a die and a press machine, the operation is troublesome and the efficiency is low;
2) The cigarette packet sewing and unpacking are troublesome, the labor intensity is high, and the efficiency is low;
3) Because the raw tobacco is compacted and compacted, and the tobacco bale is stored and transported in a laminating way, the ventilation is poor, and the core-spun tobacco is easy to press oil, burn the package or mildew;
4) Because the raw tobacco is compacted, the raw tobacco is easy to intertwine and wind and is not easy to separate when unpacked and fed, so that the dispersibility of the material is poor, the tobacco leaves are easy to be heated unevenly in the moisture regaining process, the breakage rate is increased, and the redrying quality is influenced;
5) The hemp flakes after unpacking have large loss, low recycling rate and high packing cost; in addition, the foreign matters such as twine and the like are easy to be entrained during feeding, and the preparation quality of the follow-up cut tobacco is influenced;
6) In the feeding step, manual leaf spreading is adopted, so that the labor intensity is high, the efficiency is low, more than 40 persons are needed, and the leaf spreading speed of each station is difficult to coordinate and unify, so that the raw material proportioning uniformity is greatly influenced by human factors;
