Description

Automatic glue-coating cigarette filter ventilation hole sealing device

Technical Field

The invention relates to a cigarette filter ventilation hole sealing device.

Background technique

As countries around the world pay more and more attention to tobacco and health, the World Health Organization (WHO) has proposed in recent years to use the Canadian deep smoking mode to measure smoke emissions. The Canadian deep smoking mode stipulates smoking parameters such as puffing capacity and puffing interval, and requires that the measurement be carried out in the state of completely closing the ventilation holes of the cigarette filter. Closing the ventilation holes of the filter is a necessary means to carry out research on the deep smoking mode.

At present, there are two main ways to seal the ventilation holes of the filter: special cigarette holder sealing and tape winding sealing. The special cigarette holder sealing method is expensive and must be used in conjunction with a smoking machine, so it is not suitable for promotion and use; the tape winding sealing method is divided into manual sealing and mechanical sealing. The manual tape winding sealing method has low working efficiency and poor sealing effect. Although the mechanical tape winding sealing method avoids the shortcomings of the manual tape winding sealing method, the mechanical tape winding sealing method itself changes the properties of the cigarette because the tape is wound on the cigarette filter, and bubbles are easily generated between the tape and the filter, and the tape is easily debonded. When inserting the cigarette into the standard cigarette holder, it is easy for the tape and the labyrinth ring of the cigarette holder to rub, causing part of the tape to separate from the cigarette filter, affecting the sealing effect of the ventilation holes of the cigarette filter, thereby affecting the stability of the smoke release test results.

The cylinder wall of the cigarette fixing cylinder 20 is evenly provided with first air inlet and outlet holes 17. A rubber hose 19 is inserted into the cigarette fixing cylinder 20. The inner diameter of the rubber hose 19 is larger than the diameter of the cigarette. The two ends of the rubber hose 19 are respectively connected to the upper and lower ends of the cigarette fixing cylinder 20 through sealing rubber rings 16. An annular groove is respectively provided at the two ends of the cigarette fixing cylinder 20. After the two ends of the rubber hose 19 wrap the upper and lower ends of the cigarette fixing cylinder 20 respectively, the sealing rubber rings 16 are respectively clamped in the annular grooves at the two ends of the cigarette fixing cylinder 20, so that the cigarette fixing cylinder 20 and the sealing rubber ring 16 can be firmly connected. A first annular chamber 13 and a second annular chamber 14 are provided in the rotating sleeve 2. The bottom surface of the rotating sleeve 2 is provided with an air inlet 21 communicating with the first annular chamber 13 and a second air inlet and outlet 12 communicating with the second annular chamber 14, respectively. The top surface of the rotating sleeve 2 is provided with air outlets 3 communicating with the first annular chamber 13. The angle α between the axis of the air outlet 3 and the axis of the rotating sleeve 2 is 35°, so that the outlet of the air outlet 3 faces the direction of the cigarette filter 4 inserted in the rubber hose 19. After the cigarette fixing cylinder 20 equipped with the rubber hose 19 is inserted into the axial channel of the rotating sleeve 2, An annular channel 15 is formed between the sealing rubber ring 16, the cigarette fixing cylinder 20 and the axial channel. The inner wall surface of the second annular chamber 14 is provided with a third air inlet and outlet hole 18 communicating with the annular channel 15. The second air inlet and outlet hole 12 is connected to the annular channel (15) after passing through the second annular chamber 14 and the third air inlet and outlet hole 18 in sequence. The rotating sleeve 2 is movably connected to the channel opened on the base 1 so that the rotating sleeve 2 can rotate freely in the channel, and a driving device that can rotate the rotating sleeve 2 is installed in the base 1.

The specific method of use of the present invention is as follows:

After the rubber hose 19 is inserted into the cigarette fixing cylinder 20, the rubber hose 19 protruding from the two ends of the cigarette fixing cylinder 20 is turned over and wrapped around the two ends of the cigarette fixing cylinder 20 respectively, and then fixed at the annular grooves at the two ends of the cigarette fixing cylinder 20 with the sealing rubber ring 16. After the cigarette fixing cylinder 20 equipped with the rubber hose 19 is inserted into the axial hole of the rotating sleeve 2, a tight fit is formed between the axial hole and the sealing rubber rings 16 at the two ends of the cigarette fixing cylinder 20. The cigarette is inserted into the rubber hose 19 so that the cigarette is exposed to the entire cigarette filter 4. At this time, the air pump is turned on to allow the air flow to enter the annular channel 15 after passing through the second inlet and outlet holes 12, the second annular chamber 14, and the third inlet and outlet holes 18 in sequence. At this time, the rubber hose 19 is pressurized so that the rubber hose 19 tightly wraps the cigarette. , the damping limit sliding rod 7 is moved down, the cigarette filter 4 is inserted into the blind passage 11 at the axis of the glue-coating sleeve 5, and the narrow liquid outlet 9 contacts the circumferential surface of the cigarette filter 4 in a tangential direction. After the rotating sleeve 2 rotates 720° clockwise, the adhesive wiped out from the liquid outlet 9 can completely block the ventilation holes of the cigarette filter 4. At this time, the damping limit sliding rod 7 is moved up to raise the glue-coating sleeve 5, and then the air pump is used to make the air flow pass through the air inlet 21, the first annular chamber 13, and the air outlet 3 in sequence, and then the cigarette filter 4 is blown for 10 seconds to make the glue-coated part of the cigarette filter 4 quickly air-dry, and then the air pump is started to make the air flow flow out through the first air inlet and outlet 17, the annular channel 15, the third air inlet and outlet 18, the second annular chamber 14, and the second air inlet and outlet 12 in sequence, and the decompressed rubber hose recovers its deformation to release the fixed cigarette.

The present invention selects 5 different specifications and types of filter-tipped cigarettes, and the sample parameters are shown in the following table:

1/3 of the samples were selected and a thin layer of liquid glue was uniformly coated on the ventilation holes of the cigarette filter using the method of the present invention; 1/3 of the samples were selected and the ventilation holes were sealed with adhesive tape; and the remaining 1/3 of the samples were reserved.

The physical parameters of cigarettes were tested before and after equilibration in a constant temperature and humidity chamber (temperature: 22±1°C, relative humidity: 60±3﹪, equilibration time: 48h) in three states: unsealed ventilation holes, tape-sealed ventilation holes, and adhesive-coated sealed ventilation holes of the present invention. The test results are as follows:

The test results show that the weight of cigarettes with unsealed ventilation holes and those with sealed ventilation holes with glue are basically the same, while the weight of cigarettes with sealed ventilation holes with tape increases by 6.5 to 10.2%.

After the ventilation holes are sealed, the draw resistance of the cigarette increases significantly, and the draw resistance of the ventilation holes sealed with tape and the ventilation holes sealed with glue of the present invention are basically the same.

After the ventilation holes are sealed, the ventilation rate of the cigarette filter is significantly reduced. The ventilation rate of the cigarette filter after the ventilation holes are sealed with glue is between 0.1 and 0.6%, and the ventilation rate of the cigarette filter after the ventilation holes are sealed with tape is between 0.1 and 1.0%. It is obvious that the ventilation holes sealed with glue in the present invention are better than those sealed with tape.

After the ventilation holes are sealed, the ventilation rates of the filters are basically the same before and after the samples are balanced. The ventilation rate of the cigarette filters with the glue-sealed ventilation holes of the present invention before and after the balance varies between ±(0-0.1)%, and the ventilation rate of the cigarette filters with the tape-sealed ventilation holes before and after the balance varies between ±(0-0.3)%, indicating that the glue-sealed ventilation holes of the present invention are superior to the tape-sealed ventilation holes.

Without changing the weight of cigarettes, the other physical indicators of the ventilation holes sealed by glue coating of the present invention are basically consistent with the data of the ventilation holes sealing method with tape. The effect of sealing the ventilation holes by glue coating is better than sealing with tape. The data of various indicators before and after the sample is balanced do not change much, indicating that the stability and reliability of the present invention are good, and it is suitable for sealing the filter ventilation holes of cigarettes with different circumferences and different lengths. It is an ideal device for sealing the ventilation holes of cigarette filters.
