Technical Field

The invention relates to the field of cigarette production, in particular to a pre-compacted cigarette bundle wing plate assembly capable of reducing cigarette end filament drop.

Background

The cigarette end cut tobacco is the phenomenon that cut tobacco at the ignition end of a cigarette is loose in filling and falls off. The method for calculating the cut tobacco quantity of the cigarette end part comprises the steps of firstly weighing the weight of 20 cigarette sample cigarettes by using balance, then placing the 20 cigarette sample cigarettes into a special instrument to be turned over for two minutes, taking out the 20 turned cigarette sample cigarettes after turning over after the special instrument stops turning over, placing the 20 cigarette sample cigarettes into a balance to weigh the weight of the cigarette sample cigarettes, and subtracting the turned-over weighing value from the weighing value before turning over, wherein the final cut tobacco quantity of the end part of the cigarette sample is expressed by milligrams per cigarette (mg/cig).

According to the national standard of tobacco industry, the cut tobacco quantity of the end part of the filter tip cigarette should be less than or equal to 8.0mg/cig, otherwise, according to the national standard, the cigarette with the B-type quality defect is determined according to the physical index condition. Because the phenomena that the end drop filaments do not accord with the quality standard specified by the national standard often occur in the production of the new world of the Fine Branch (the fine Branch is 5.4mm), the flat blue fashion (the fine Branch is 5.4mm), the green water Qingshan (the fine Branch is 5.4mm) and the Yipin lotus (the coarse Branch is 7.8mm), the research on the problem of solving the problem that the end drop filaments do not accord with the technological index value specified by the national standard is very important.

The method does not consider the process characteristics of the cut tobacco structure, and only analyzes and improves the parts influencing the end part cut tobacco quantity exceeding the national standard requirement in the production process of the cut tobacco suction forming part of the ZJ17 cigarette making machine set.

Fig. 1 is a schematic view of the main structure of a wire suction forming part of a conventional ZJ17 cigarette making machine set. The working principle is that the silk suction belt 11 moves between a front wing plate and a rear wing plate, and the inner sides of the front wing plate and the rear wing plate are respectively provided with an alloy partition plate 12 to prevent the cigarette tows in motion from wearing the front wing plate and the rear wing plate; the positioning block 13 is positioned between the two alloy partition plates 12, the positioning block 13 is fixed by the positioning pin and the positioning sleeve, the bottom surface and the top surface of the positioning block 13 are not parallel, and the bottom surface is not in contact with the wire suction belt 11, so that the wire suction belt can only play a role in positioning the distance between the front wing plate and the rear wing plate, and is used for ensuring that the wire suction belt 11 runs stably, does not shake or is blocked in the front wing plate and the rear wing plate. The cigarette tow is adsorbed on the silk suction belt 11 with certain tension force, and the magnetic beads 14 play a role in supporting the silk suction belt 11. After the tobacco bundles are leveled by the preorder cleaver mechanism, the density of the tobacco stream in the operating state can form a regular multi-few-micro wave state, and the tobacco stream enters the front wing plate section and the rear wing plate section after being combed at the rear end of the front guide rail for a short time. The cigarette tows run between the front wing plate and the rear wing plate, the compaction wheel 15 is a driven wheel, the cigarette tows which are about to enter the filament shoveling knife 16 are rapidly compacted to ensure the compactness of the cigarette tows, and finally the cigarette tows are stripped from the filament sucking belt 11 under the action of the filament shoveling knife 16.

Wherein the length of the front wing plate is 140mm, the diameter of the compaction wheel 15 is 95.5mm, the distance from the compaction wheel 15 to the bottom plate of the tobacco pipe is 5.2-5.4mm, and the compaction wheel 15 is used for shaping and compacting the tobacco bundles. Thus, a sharp compacting point is formed between the bottom end of the compacting wheel 15 and the surface of the bottom plate of the tobacco pipe, and the sharp compacting point is used for compacting and shaping tobacco bundles with different thicknesses. In the process, the cigarette tows in operation are changed in displacement, and when the compacting wheel 15 is pressed rapidly, the nylon cut tobacco suction belt 11 with a certain tension force can be slightly deformed and bent upwards under the action of backward displacement of the cigarette shreds, and the cigarette shreds are deformed along with the deformation of the nylon cut tobacco suction belt, so that the position of the ignition end of the cigarette end is changed.

Referring to fig. 2, this is mainly because a cavity (black area shown) with a height of about 2mm and a length of about 40mm is formed between the suction belt 11 and the front and rear wing plate positioning blocks 13 during operation. The displacement cut tobacco after the rapid compaction of the compaction wheel 15 jacks up the cut tobacco suction belt 11 and fills the cavity area which is approximately triangular, thereby influencing the accuracy of the cigarette end tightening position and the cut tobacco dropping amount.

Therefore, in order to solve the problem that the cut tobacco quantity of the end part of the cigarette exceeds the national standard requirement, the problem of the cigarette end tightening offset generated by the part needs to be overcome, the structure of the cut tobacco suction forming part of the cigarette making and tipping machine set is reformed, and the triangular cavity area is eliminated.
