Embodiment 1

[0016] For the test method for the sealing degree of the soft pack of cigarettes of the same specification, (1) Take five packs of soft pack cigarettes (marked as a, b, c, d, e) and wipe them clean.

[0017] (2) Weigh with an electronic balance and record the data. The results are shown in Table 1.

[0018] (3) such as figure 1 As shown, the tested cigarette 1 is put into the cigarette fixing frame 6, and the cigarette is immersed into the liquid 2 in the container 4 through the telescopic rod 3. The pressure of the liquid 2 on the tested cigarette 1 is 3KPa, the immersion time is 20 minutes, and the liquid temperature 20°C.

[0019] (4) At the initial stage of immersion of the tested cigarette 1, observe whether there are bubbles on the surface of the package. If there are bubbles, record the parts of the cigarette. The results are shown in Table 1.

[0020] (5) After the immersion is completed, the cigarette fixing frame 6 is separated from the liquid by the telescopic rod 3, the c...

Embodiment 2

[0026] For the test method for the tightness of hard packs of cigarettes of the same specification, (1) Take five boxes of hard pack cigarettes (marked as A, B, C, D, E) and wipe them clean.

[0027] (2) Weigh with an electronic balance and record the data. The results are shown in Table 2.

[0028] (3) such as figure 1 As shown, the tested cigarette 1 is put into the cigarette fixed frame 6, and the cigarette is immersed into the liquid 2 in the container 4 through the telescopic rod 3. The pressure of the liquid 2 on the tested cigarette 1 is 5KPa, the immersion time is 30 minutes, and the liquid temperature 20°C.

[0029] (4) At the initial stage of immersion of the tested cigarette 1, observe whether there are bubbles on the surface of the package. If there are bubbles, record the locations of the bubbles. The results are shown in Table 2.

[0030] (5) After the immersion is completed, the fixed frame 6 of the tested cigarette 1 is separated from the liquid by the telescopic rod ...

Abstract

The invention relates to a testing method for cigarette packing sealing intensity. The method comprises the following steps of: weighing cigarettes by a high-accuracy balance scale; soaking the weighed cigarettes in a container with liquid; taking out the soaked cigarettes after a period of time; wiping the liquid on the surfaces of the cigarettes to be dry; weighing for the secondary time; judging the cigarette packing sealing intensity according to the change of the weights of the cigarettes before and after the soaking. The parts requiring improvement of the packing sealing intensity can be found by observing the bubbling positions of the cigarettes during the soaking and the moisten positions of the soaked cigarettes. The method can overcome the defects in the prior art that only the packing sealing intensity of small-box type soft packing can be tested, and the parts requiring improvement of the packing sealing intensity can bot be found, and can be used for performing sealing intensity testing on the cigarettes with different types of soft packing, hard packing, soft packing hardening and striped packing and finding the parts requiring improvement of the packing sealing intensity.

Description

Technical field [0001] The invention relates to the tobacco industry, in particular to a method for testing the tightness of cigarette packages. Background technique [0002] The existing cigarette package sealing test is to use the method of inflating the cigarette package. First, use the hole cone to penetrate all the packaging materials on the tested surface of the cigarette small box packaging to form a hole area not less than 1mm 2 Then place the cigarette box at the air nozzle of the test instrument. When placed, the air hole of the cigarette box under test is opposite to the air nozzle. The box is surrounded and absorbed by the sealing plate of the instrument at the same time, and finally the compressed air passes through the nozzle. The cigarette package is inflated, and when the pressure in the cigarette package is balanced with the pressure in the pressure measurement chamber, the pressure sensor indicates the measurement result. This leak tightness test method has the...
