Description

A shredded tobacco sorting device and process

technical field

The invention belongs to the technical field of on-line sorting shredded tobacco, and in particular relates to a shredded tobacco sorting device and process.

Background technique

With the continuous innovation and development of cigarette processing technology and process concepts, cigarette processing is entering the stage of refined processing in an all-round way. Among them, group processing, flexible processing and product homogenization are the difficulties in the implementation of fine processing and the hot spots of technology development. Judging from the current development status, the raw material modular processing technology that adopts different processing methods and processing parameters according to different origins and grades of tobacco leaf raw materials is relatively mature, which has laid an important foundation for improving the use value of raw materials and broadening the scope of raw materials. However, judging from the level of product quality homogeneity, which is a key evaluation standard for refined processing, there are still some problems to be solved, mainly the uniformity of blending of each component of shredded tobacco within a batch and the uniformity of flavoring and adding materials that need to be further improved , the key influencing factor is the uniformity of tobacco length.

Existing studies have shown that the optimal length of shredded leaf structure distribution should be 2.00-4.75 mm (different formula products have slight differences), but the length distribution of shredded leaf is extremely uneven in actual production, and the test data show that the proportion of shredded leaf > 10mm Accounting for about 40%, the longest shredded leaves can reach more than 100mm. These over-long shredded shreds are easy to entangle and curl each other during processing, and intertwined to form braids or agglomerated shredded tobacco, which is not easy to mix evenly with other shredded tobacco. The fluctuation of the arrangement during the rolling process is also relatively large. It not only affects the stability of the physical quality of rolling, but also directly affects the uniformity of the actual blending of different components of shredded tobacco and different modules of shredded tobacco, which in turn affects the uniformity of flavoring and feeding. For consumers, there are differences in the stability and consistency of the smoking quality of each cigarette. Therefore, it is necessary to optimize and regulate the structure of leaf silk, eliminate excessively long leaf silk, reduce the filament rate, and obtain leaf silk with better length uniformity. However, too short shredded tobacco also has adverse effects. Firstly, too short shredded tobacco affects the filling performance of shredded tobacco. Secondly, if the shredded tobacco ratio is too high, the short-cut ratio of cigarettes will increase, and the amount of shredded shreds at the end will deteriorate, thereby increasing defective products and affecting cigarette consumption.

Preferably, a sundry collection box is arranged below the shredded tobacco loose box.

Preferably, the positive pressure fan is connected to the left and right sides of the bottom of the shredded tobacco loose box through left and right positive pressure pipelines respectively.

Preferably, a brush is provided on the upper surface of the lower web of the mesh conveyor belt located on the right side of the loose shredded tobacco box.

Preferably, an air blowing pipe is provided on the upper surface of the lower web of the mesh conveyor belt located on the right side of the shredded tobacco loose box.

Preferably, the throwing belt is inclined upwards, and the included angle with the horizontal plane is 2.5-3.5°.

The shredded tobacco sorting process includes the following steps: turn on the positive pressure fan, send the shredded tobacco into the feeding hood by the vibrating conveyor, then the shredded tobacco falls on the throwing belt through the feeding air lock, and the throwing belt throws the shredded tobacco into the loose shredded tobacco The shredded tobacco moves upward in the loose shredded tobacco box under the action of wind force, the shorter shredded tobacco passes through the lower section of the mesh conveyor belt and enters the negative pressure suction duct, and the longer shredded tobacco is adsorbed on the lower section of the mesh conveyor belt. The lower surface moves to the right with the mesh conveyor belt, and finally enters the filament blanking box.

The beneficial effect produced by the present invention is that the present invention adopts flexible wind sorting. Compared with mechanical screening and sorting, it can effectively separate long filaments and short filaments without additionally increasing shredded tobacco. It has a loose and impurity removal effect.
