Problems solved by technology

At present, most of the cigarette industry enterprises still use the air-inflated cigarette case sealing degree measuring instrument, and repurchasing the negative pressure suction method cigarette case sealing degree measuring instrument will inevitably cause waste of equipment resources
On the other hand, with the alternation of old and new standards, there are two kinds of equipment in the cigarette industry, the inflation method and the negative pressure suction method, to simultaneously inspect and control the sealing degree of cigarette packages. It is difficult to compare the sealing degree of cigarette packages under different test methods.
In addition, even if the same equipment under the same test method is used for the same cigarette case test, the measurement data will have a large error, and the comparability between the data is poor.
At the same time, when re-inspecting the samples of the tightness of the small cigarette box, the test data due to the damage of the small box seal cannot be well corresponded to

Embodiment 1

[0042] Cigarette case samples 1-4 were tested with a negative pressure suction method cigarette case sealing degree measuring instrument. The instrument model is: PSTNE100 negative pressure suction type cigarette case sealing degree tester (Hefei Zhongwo Instrument Technology Co., Ltd. ), the pumping flow rate is 200mL / min, and the measuring range is 0~-5.00kPa. Among them, -5.00kPa is also the same as 5.00-kPa.

[0043] The specific test method is: pre-punching a hole in the center of the cigarette box, using negative pressure suction method equipment to punch holes with a diameter of 0.30 mm on the cigarette box, and then using the ring suction cup 444 to suck the cigarette box 555, and the ring Through hole 333 is arranged in the middle of shape suction cup 444 (through hole 333 is all greater than small box pre-punched hole diameter), negative pressure suction method (see Figure 9 One end of the through hole 333 communicates with the cigarette case 555, and the other end...

Embodiment 2

[0053] Cigarette case samples 1-4 were tested by an inflatable cigarette case airtightness measuring instrument, the instrument model is: YM-OPT type inflatable cigarette case airtightness tester (YM International Technology, South Korea), working pressure 0.5MPa, Range 0~1500mL / min.

[0054] The specific test method is as follows: pre-punching a hole in the center of the cigarette case, using the inflation method equipment to punch a hole with a diameter of 0.40 mm on the cigarette case, and then using the ring-shaped suction cup 444 to suck the cigarette case 555, and the middle of the ring-shaped suction cup 444 There are through holes 333 (through holes 333 are all greater than the pre-punched diameter of the small box), and the inflation method (see Figure 10 ) One end of the through hole 333 communicates with the cigarette case 444, and the other end is inflated through the ventilation pipe 222 under a stable working pressure. During the measurement, the gas filling me...

Embodiment 3

[0063] Two samples of soft pack cigarette case sample 5 and cigarette case sample 6 were taken respectively.

[0064] The cigarette case sample 5 was tested by a negative pressure suction method cigarette case sealing degree measuring instrument, and the detection method was the same as in Example 1. The test result was that the negative pressure suction method sealing degree of the cigarette case sample 5 was 4.25-kPa, Further, the method of Example 1 was used to test the standard part, and the result was that when the sealing degree of the negative pressure suction method was 4.25-kPa, the scale mark of the standard part was 2, and the sealing performance of the sample was excellent.

[0065] Cigarette case sample 6 is tested by an air-inflated cigarette case sealing degree measuring instrument, the detection method is the same as in Example 2, and the test result is that the air-inflating method sealing degree of cigarette case sample 6 is 120mL / min, further, using the embod...

Abstract

The invention discloses a rotary cigarette case sealing performance test standard component comprising: a base (1) which comprises a supporting part (11) and an extending part (12), wherein a first airflow channel (13) is formed in the base (1), and a first through hole (14) which is formed in the side wall of the base (1) and communicates with the first airflow channel (13) is formed in the sidewall of the base (1); a cover cap (2), wherein a cavity (21) is formed in the cover cap (2), and a second through hole (22) penetrating through the side wall of the cover cap (2) and communicating with the cavity (21) is formed in the side wall of the cover cap (2); and an extending part (12) which is located in the cavity (21), wherein the cover cap (2) can rotate relative to the base (1), and the first through hole (14) and the second through hole (22) are completely overlapped or partially overlapped or completely not overlapped. According to the invention, the rotary cigarette case sealingperformance test standard component is designed and is used for rapid proofreading and association of detection data of two devices with different principles, and the problem that the sealing degreesof cigarette cases are difficult to compare under different test methods is avoided.

Description

technical field [0001] The invention belongs to the field of cigarette packaging boxes, and in particular relates to a rotary cigarette box sealing test standard part. Background technique [0002] The airtightness of cigarette packs is closely related to the moisture content of cigarettes, anti-mildew and preservation of original fragrance, storage life, etc. Therefore, controlling the airtightness of cigarette packs is of great significance to maintain the quality of cigarettes. The poor sealing of cigarette packs is mainly caused by the packaging machine during the production process due to film folds, slack, air bubbles in hot-sticking, not tight and smooth cut surfaces, improper use of BOPP film specifications, etc. Cigarette production workers are concerned about the above reasons. Corresponding adjustment methods and improvement measures are put forward for different packaging models, which can effectively improve the airtightness of small boxes. At the same time, qua...
