A kind of pre-pressing packing process of filamentous tobacco material

Abstract

The invention discloses a process for pre-pressing and boxing filamentary tobacco materials, through material temporary storage-cigarette box flipping and docking-feeding lifting-thinning metering-reciprocating material spreading-material pre-pressing-material boxing-cigarette box The production process of temporary storage and distribution adopts the traditional vertical box packing process, which can not only improve the packing uniformity and packing density of tobacco materials in the box, reduce transportation costs, but also have low requirements on the site and reduce process equipment The floor area and factory design requirements can indirectly reduce the equipment cost, and can effectively reduce the shred rate. It is suitable for packing and distribution of tobacco materials such as shredded tobacco, expanded shredded tobacco, thin slices, and shredded stems. It has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of material boxing, in particular to a process for prepressing and boxing filamentary tobacco materials. Background technique [0002] During the processing of cigarette tobacco materials, including threshing, re-cured tobacco sheets, reconstituted tobacco leaves, and reconstituted tobacco shreds, tobacco materials need to be boxed for transshipment or storage in the next process. At present, the packing process of tobacco materials adopts the vertical packing method, that is, the mouth of the material box faces upwards, and the tobacco material falls into the box from the mouth of the box. Since the material box used for loading tobacco materials often has a small space, Coupled with the fluffy characteristics of the tobacco material, the tobacco material is easy to form a pile in the middle after falling into the box, and it is impossible to realize the uniform distribution of the tobacco material in the b...

At present, the packing process of tobacco materials adopts the vertical packing method, that is, the mouth of the material box faces upwards, and the tobacco material falls into the box from the mouth of the box. Since the material box used for loading tobacco materials often has a small space, Coupled with the fluffy characteristics of the tobacco material, the tobacco material is easy to form a pile in the middle after falling into the box, and it is impossible to realize the uniform distribution of the tobacco material in the box, resulting in poor packing density uniformity. At the same time, Tobacco materials are packed in natural stacks, and the loading capacity is low, which greatly increases the use of cigarette boxes and the floor space of storage warehouses, reduces the transportation efficiency of tobacco materials, and increases transportation costs

Although the current threshing and re-curing tobacco sheet and reconstituted tobacco leaves have used pre-pressing packaging for packing, that is, after the materials are piled up to a certain height, a compacting device is used to pre-press and pack the packing box once, but because the filling bin adopts a vertical design , the indenter must be lifted out of the compaction system before the material can be fed. The compaction device should meet the travel requirements of the compaction system. The height of the entire processing process exceeds 20 meters. The system is huge and has high requirements for the design of the plant, which greatly increases the equipment cost. And the shredded tobacco rate is high, which causes a great waste of materials
