Description

A uniformly ventilated cigarette online punching structure and method

Technical field

The present invention relates to the technical field of cigarette preparation. In particular, the present invention relates to a uniformly ventilated cigarette online punching structure and method.

Background technique

Smoking materials directly determine the physical parameters of cigarettes, affect the burning state of cigarettes, and play a key role in the appearance quality of cigarettes, mainstream smoke components, and sensory quality. They are the main control method for smoke indicators in cigarette production. One, it can be divided into cigarette paper burning end and filter rod filtering end according to its mechanism of action. Smoking materials determine the combustion state of conventional cigarettes to a certain extent, and affect the proportion of mainstream smoke components through filtration and dilution, ultimately affecting the sensory quality of smoke. The design and proportioning of cigarette material parameters is one of the most direct and simple conventional technical ways to improve the smoke indicators and sensory quality of cigarettes. Smoking materials determine the combustion state of conventional cigarettes to a certain extent, and affect the proportion of mainstream smoke components through filtration and dilution, ultimately affecting the sensory quality of smoke. The design and proportioning of cigarette material parameters is one of the most direct and simple conventional technical ways to improve the smoke indicators and sensory quality of cigarettes.

There are two ways to achieve ventilation of cigarette paper: online punching and pre-punching. Pre-punching is often used in production, that is, perforated cigarette paper (electrostatic drilling or laser drilling) is used to connect high-transparency filter rods and cigarette rods rolled from high-transparency forming paper. By using filter rod ventilation to dilute or reduce the mainstream smoke, the purpose of reducing coke is achieved. Currently, cigarette paper is perforated in a linear circumferential direction. Generally, the perforation zone is controlled in 1-5 rows, and each row is different according to the diameter of the cigarette. Can drill 10-25 holes.

In addition, the current laser online punching mechanism is a single machine, which only sets the power and time of laser punching to punch through the tipping paper and forming paper. For example, the Chinese patent invention patent CN101862910A discloses a parallel laser punching method for cigarette tipping paper. Hole method, the K pulse laser beam output from the laser array composed of K pulse lasers arranged in parallel is coupled and transmitted through the optical path conversion system, and then focused on the surface of the continuously moving tipping paper to form a pattern along the width direction of the tipping paper. K-channel punching pulse lasers densely arranged in linear or diagonal shapes; the tipping paper online speed detection system detects the movement speed of the tipping paper in real time, and feeds the speed information back to the control system, and then sends out signals through the control system The control signal controls the light emission timing, pulse frequency and pulse interval time of each pulse laser in the laser array, and cooperates with the continuous movement of the tipping paper to punch small holes arranged in patterns or characters on the surface of the tipping paper, where K= 2~10. The above invention also provides a device for implementing the above method, which has a simple structure, stable operation and high processing efficiency.

technical problem

However, the above-mentioned laser drilling method still has the following problems: when punching holes in cigarette paper, since the positions of different cigarettes are different, the number of layers of filter rod forming paper is different, and the position of the tipping paper is different. For example, when punching holes in ternary composite filter rod cigarettes, the punching position is at the overlap position of the tipping paper. If the overlap position of the filter rod base rod forming paper, the overlap position of the primary composite forming machine, and the overlap position of the secondary composite forming paper are all Located at the same position, online punching of the tipping paper requires punching through 8 layers of paper, while other locations only need to punch through 4 layers of paper. Since the power of the laser drilling equipment is the same, the number of paper layers that need to be punched is between 4-8. . Due to the changes in the punching positions, there are many layers of paper in some places, and the paper may not be punched through, so the ventilation effect cannot be achieved. According to the ratio of the overlap width of 2mm to the circumference of the cigarette, the circumference of slim cigarettes is 17mm, the circumference of medium cigarettes is 20mm, and the circumference of regular cigarettes is 24mm. If there are no holes in the overlap position, the ventilation rate will generally be affected by about 10%, resulting in tar and sensory effects. Large fluctuations in quality; in addition, it is impossible to detect the filling of the internal filament bundles in the filter rod, and cannot dynamically change according to the difference in tightness of the internal filament bundles, resulting in uneven ventilation at various locations around the circumference of the cigarette and poor smoking taste.

Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient cigarette online perforation structure with uniform ventilation.

The purpose of the present invention is to provide a device that is simple to set up. By adding a detector, the material, thickness and number of layers of cigarette paper are obtained, and the paper data is fed back to the laser drilling part in real time.

The formed cigarettes are sent to the conveying part 5 for transmission in the direction 6 of the cutting part, and the laser drilling part 3 is set above the conveying part 5 for cigarette making. The outside is surrounded by holes.

In this embodiment, when the cigarette 10 is transported on the conveying part 5, it is grabbed by the cigarette clamping part 1, and then one end of the cigarette 10 is clamped by the two clamping plates 12 of the cigarette clamping part 1 , the other side of the first chassis 11 for fixing the two clamping plates 12 is provided with a motor 13 that drives the first chassis 11 to rotate. When the motor 13 works, both the first chassis 11 and the cigarette 10 rotate, thereby making it convenient The punching part 3 can punch holes around the cigarette when punching the cigarette.

After one end of the cigarette 10 is clamped, a cigarette detection part 2 is provided in the extending direction of the other end of the cigarette 10. The second chassis 21 of the cigarette detection part 2 is provided with an isotope scan for obtaining the parameters of the cigarette 10. The instrument 22 is used to perform targeted drilling of the cigarette 10 in a convenient and parameterized manner. The punching part 3 is provided directly above the cigarette 10, and the laser output head 31 provided below the punching part 3 can emit laser light downward, thereby Make holes on the surface of the lower cigarette 10.

Here, the first chassis 11 of the cigarette clamping part 1 and the second chassis 21 of the cigarette detection part 2 are arranged in parallel and coaxially, and the cigarette 10 clamped by the output shaft of the motor 13 and the clamping plate 12 is also They are all coaxially arranged with the first chassis 11, and the laser output head 31 is arranged directly above a certain point on the central axis of the cigarette 10.

This ensures that the cigarette paper parameters are obtained, the cigarette paper can be punched through, and the ventilation of the cigarette is ensured. Rate.

In addition, the isotope scanner 22 takes a cross-sectional image of the cigarette, not only obtains the data of the cigarette paper, but also obtains the data of the tightness of the shredded tobacco inside the cigarette paper, and feeds it back to the motor 13. The motor 13 itself is an infinitely variable speed motor, which can adjust the tightness of the shredded tobacco according to the degree to adjust the rotational speed of the motor 13. Since the time interval between two laser outputs of the laser output head 31 is fixed, the rotational speed of the motor 13 directly affects the distance between the two adjacent laser holes 101 on the outside of the cigarette 10; For example: the higher the compactness of the tobacco, the higher the ventilation requirements, the motor 13 rotates slowly, and the distance between two adjacent laser holes 101 is short, that is, the laser holes 101 are denser; this can ensure uniform ventilation of the entire cigarette. higher.

It should be noted that the isotope scanner 22 is disposed on the outer edge of the second chassis 21. In fact, the isotope scanner 22 is aimed at the part of the cigarette 10 that is about to rotate below the laser output head 31, that is, the The direction in which the isotope scanner 22 faces is located in the rotational front of the direction in which the laser output head faces.

Finally, the lower end of the punching part 3 is also provided with an infrared probe 32 extending in the same direction as the laser output head 31; the infrared probe 32 detects the temperature of the laser hole 101 in real time to prevent the temperature from being too high during laser drilling and damaging the cigarette. The tobacco tows within 10 seconds cause burning, which affects the smoking texture of the cigarette. Here, the burning temperature of the cigarette paper and the tows is different. The infrared probe 32 detects the temperature of the punched part in real time. Once the tobacco shreds If the laser beam causes burning, it is an abnormal state of perforation, then a signal is sent to the power controller 33 to correct the laser perforation parameters, that is, the output power of the laser output head 31 is reduced; otherwise, the cigarette paper is burning by the laser, which is a normal perforation state. hole status, no correction signal is sent.
