Description

Tipping paper on-line punching structure and method based on cigarette data detection

Technical Field

The invention relates to the technical field of cigarette preparation, in particular to an on-line perforating structure and method for tipping paper based on cigarette data detection.

Background

The cigarette material is mainly three paper and one rod (cigarette paper, tipping paper, forming paper and filter rod) directly determines the physical parameters of the cigarette, influences the combustion state of the cigarette, plays a key role in the appearance quality of the cigarette, the main stream smoke components, the sensory quality and the like, is one of main control modes of smoke indexes in the cigarette production, and can be divided into a cigarette paper combustion end and a filter rod filtering end according to an action mechanism. The combustion state of the conventional cigarette is determined by the cigarette material to a certain extent, and the main stream smoke component proportion is influenced through the filtering and dilution effects, so that the sensory quality of smoke is finally influenced. Through the design and the proportion of the parameters of the materials for the cigarettes, the method is one of the most direct and simple conventional technical approaches for improving the indexes and the sensory quality of the cigarette smoke. The combustion state of the conventional cigarette is determined by the cigarette material to a certain extent, and the main stream smoke component proportion is influenced through the filtering and dilution effects, so that the sensory quality of smoke is finally influenced. Through the design and the proportion of the parameters of the materials for the cigarettes, the method is one of the most direct and simple conventional technical approaches for improving the indexes and the sensory quality of the cigarette smoke.

There are two ways to realize the ventilation of tipping paper: in-line punching and pre-punching. The high-permeability filter rods and rods rolled from high-permeability formed paper are usually produced by pre-perforating, i.e. by perforating tipping paper (electrostatic perforation or laser perforation). The main stream smoke is diluted or reduced by adopting filter stick ventilation, so that the purpose of reducing tar is achieved, the conventional tipping paper is perforated in a linear circumferential direction, the perforated hole belts are generally controlled in 1-5 rows, and 10-25 holes can be perforated in each row according to the different diameters of cigarettes.

In addition, the current laser on-line punching mechanism is single in machine, only the power and time of laser punching are set for punching tipping paper and forming paper, for example, chinese patent invention patent No. 101862910A discloses a parallel type laser punching method for cigarette tipping paper, K paths of pulse laser beams output by a laser array formed by K paths of pulse lasers which are arranged in parallel are coupled and transmitted by a light path conversion system and focused on the surface of tipping paper which moves continuously, so that K paths of punching pulse lasers which are arranged densely in a straight line shape or oblique line shape along the width direction of the tipping paper are formed; the method comprises the steps of detecting the movement speed of tipping paper in real time by a tipping paper online speed detection system, feeding back speed information of the tipping paper to a control system, sending control signals to control the light emitting time sequence, the pulse frequency and the pulse interval time of each pulse laser in the laser array by the control system, and punching small holes distributed in a pattern or character arrangement mode on the surface of the tipping paper in cooperation with the continuous movement of the tipping paper, wherein K=2-10. Said invention also provides a device for implementing said method, and said device is simple in structure, stable in operation and high in processing efficiency.

However, the following problems still remain in the laser drilling method: when punching holes on tipping paper, the positions of the holes are different according to the different layers of the filter stick forming paper, the positions of the tipping paper openings are different, and taking the most extreme ternary composite filter stick cigarette punching as an example, the punching positions are at the positions of the tipping paper openings, if the positions of the tipping paper openings of the filter stick base stick forming paper, the positions of the primary composite forming machine openings and the positions of the secondary composite forming paper openings are all positioned at the same position, the tipping paper needs to be punched through 8 layers of paper in an online punching mode, and the other positions only need to be punched through 4 layers of paper, and the layers of paper needing to be punched are between 4 and 8 layers due to the fact that the laser punching equipment power is the same. Because the punching position is not fixed, the number of layers of paper is more in some positions, and the paper is probably not opened, so that the ventilation effect cannot be realized. According to the proportion of the lap opening width of 2mm accounting for the circumference of the cigarettes, the circumference of the slim cigarettes is 17mm, the circumference of the medium cigarettes is 20mm, and the circumference of the conventional cigarettes is 24mm, if no holes are punched at the lap opening position, ventilation rate is generally affected by about 10%, so that tar and sensory quality are greatly fluctuated; in addition, the filling property of the internal tows of the filter rod cannot be detected, and dynamic change cannot be carried out according to the difference of the tightness degree of the internal tows.

Therefore, in order to solve the above problems, it is necessary to design a reasonably efficient on-line punching structure of tipping paper based on smoke data detection.

In the invention, the production process of the cigarettes is as follows: wrapping the cigarette tow and the filter rod on forming paper at a cigarette forming part 4; then delivering the cut-off paper to a cigarette tipping part 5 for tipping, leading tipping paper out of a bobbin paper device in the cigarette tipping part 5, cutting the tipping paper into pieces after passing through an automatic tipping paper tipping device, a paper feed roller and a gluing device, delivering the pieces to a closing drum, adhering the pieces to the outer side of a cigarette wrapped with formed paper, rubbing and drying the pieces, and ironing the tipping paper glue solution; finally, the cigarettes after being assembled are conveyed to a cutting part 6 through a conveying part 7 for cutting, and the subsequent cigarettes are obtained; and a laser perforating part 8 is arranged above the conveying part 7 for perforating around the outside of the cigarettes.
