Description

Positioning, boxing and compacting tobacco shred equipment

Technical Field

The invention relates to equipment for compacting a certain amount of cut tobacco in a tobacco box, which is used in a cigarette factory, in particular to equipment for compacting the cut tobacco in a positioning and boxing way, and belongs to the technical field of tobacco equipment.

Background

In the tobacco industry, the production of tobacco shreds is an important link, one link in the production of the tobacco shreds needs to be stored and transported in a special cigarette box, the invention aims at a paper cigarette box which is processed by using corrugated paper as a raw material, and the cigarette box can be recycled for many times.

At present, equipment for packing quantitative tobacco shreds into a tobacco box for compaction and protecting the tobacco box in the packing and compaction processes is lacked, most of tobacco factories manually pack the tobacco shreds and compact the tobacco shreds, and the problems of tobacco shred scattering, large dust, low efficiency, low tobacco shred compaction rate and the like generally exist in manual packing.

According to the initial search, the current prior art comprises a horizontal tobacco shred packing system and packing method (201810816687.4), an accurate metering automatic packing system (201821474291.8), tobacco shred compacting equipment (201822009213.7) in the tobacco shred packing process and the like.

Through research and analysis on the prior art, the technical means adopted by the prior art and the defects or shortcomings are mainly found as follows:

(1) the patent mainly discloses a mechanism for uniformly distributing and compacting tobacco shreds in a tobacco box, the mechanism is characterized in that materials such as the tobacco shreds are conveyed into the tobacco box through a bidirectional running belt conveyor capable of moving left and right on a sliding groove, the tobacco shreds inside the tobacco box are compacted through matching of an air cylinder and the tobacco box, and the compacted tobacco shreds are taken out by a manipulator and are conveyed to the next station on a conveying belt. It can be known from the description of the patent that after the tobacco shreds are compacted in the tobacco box, the tobacco box needs to be taken out from the pre-compaction bin by a left manipulator and a right manipulator and then placed on a conveying track after actions such as overturning. The manipulators arranged on the left side and the right side and the conveying tracks matched with the equipment occupy large space on the left side and the right side, and the use of the manipulators greatly increases the cost; on the other hand, in the process of boxing the materials such as tobacco shreds and the like, a sealing device is not needed, and a large amount of dust is diffused to the surrounding environment.

(2) The patent discloses a tobacco shred containing conveyor, a material stirring roller, a weighing system and a tobacco shred compacting system. The tobacco shreds are conveyed to the weighing system by the conveyor, after the weight of the tobacco shreds reaches a certain value, the weighing system conveys the weighed tobacco shreds into the metering pipe, the tobacco shreds in the metering pipe fall into the tobacco box under the control of the turning plate, the tobacco box rises upwards under the action of the jacking mechanism and is attached to the discharge port, and the air cylinder drives the pressure head to compact the tobacco shreds in the tobacco box downwards.

(3) The patent discloses a device for compacting tobacco shreds in a cigarette box by using a gear and rack driving pressure head.

In a word, the prior art can not realize positioning, boxing and compacting the tobacco shred packaging box (tobacco box) at the same time, and has the defects of not compact enough structure, large occupied area, unsealed integral structure, low boxing and compacting operation efficiency and the like in different degrees.
