Description

Technical Field

[0001] The invention relates to the field of cigarette package performance testing instruments, in particular to a cigarette package indentation performance testing instrument and a testing method. Background Art

[0002] Cigarette packaging boxes include paper cigarette boxes, aluminum cigarette boxes, and tinplate cigarette boxes. Paper cigarette boxes are the most widely used, including soft packs and hard packs. Soft packs are soft to the touch and round in appearance; hard packs are relatively hard and square in appearance. Cigarette packaging boxes need to have good air tightness and moisture resistance: prevent cigarettes from being damp and polluted by the air, and maintain the quality of cigarettes; good mechanical properties: ensure the stability and integrity of the packaging during transportation, storage and carrying; good heat sealing: facilitate the sealing operation during the packaging process to ensure that the packaging is well sealed; good printing performance: realize the identification and decoration of cigarettes, such as printing brand logos, patterns, warnings, etc.; environmental protection and safety: meet environmental protection requirements and do not use substances harmful to the environment; at the same time, ensure the health and safety of production workers and consumers.

[0003] Cigarette packaging indentation is an important link in the cigarette production process. In cigarette packaging, whether it is hard box or soft box packaging, indentation can make the paper bend accurately along the preset lines during the folding process, thereby forming a regular packaging box shape, ensuring the overall beauty and structural stability of the packaging. However, if the toughness of the packaging paper is poor, during the folding process, the paper fibers at the crease cannot withstand the stress generated by the folding, which can easily cause the ink layer and the aluminum layer to break along with the paper. For example, some low-quality papers have shorter fibers and are not tightly combined, and are easy to break when subjected to external force. Secondly, if the folding angle of the cigarette box does not meet the design requirements, too large or too small folding angles will cause uneven stress distribution at the crease, and ultimately increase the risk of bursting of the ink layer and the aluminum layer. Therefore, it is necessary to have corresponding instruments to test the indentation performance of cigarette packaging, observe whether the ink layer and the aluminum layer at the crease have bursting and the degree of bursting after multiple folding, and touch with fingers to observe whether de-inking or de-aluminization occurs. Summary of the invention

[0030] A table 11 is disposed on the upper plane of the base 1, a gap is left between the rear end of the table 11 and the support frame 2, and the sample pressing mechanism is located above the table. More specifically, the support frame 2 is mounted on the table 11, and the gap between the rear end of the table 11 and the support frame 2 is left as a space for the folding mechanism and / or the sample block mechanism to move.

The two sides of the bending arm 5 are movable fixed ends, and a pressure roller is arranged between the two ends of the movable fixed end; the side view of the movable fixed end is "レ", and its right end is connected to the transmission device 6, and is folded with the left end as the center of the circle, and the pressure roller is fixed at the turning point of "レ". When the bending arm 5 is working, it is flipped upward from the bottom through the transmission device 6 and contacts the cigarette packaging box through the reserved gap between the rear end of the table 11 and the support frame 2, and the pressure roller folds it upward along the indentation. Among them, the transmission device 6 drives the bending arm 5 to rotate through the belt drive and the connecting rod.

[0035] The cigarette package indentation performance tester can fold the cigarette package up to 180° through the sample pressing mechanism and the folding mechanism, and can reset and flatten the folded cigarette package through the cigarette package indentation reset mechanism, so that the next folding can be performed. Through the combination of the above actions, multiple folding of the cigarette package can be achieved.

[0036] As an optional embodiment of the present application, a sample block mechanism is provided on the base 1 as a reference line for placing the cigarette package. Figure 2 As shown, the sample block mechanism is located between the support frame 2 and the folding mechanism, and includes a blocking rod 71 and a shifting device, and the blocking rod 71 is arranged on the shifting device.

[0037] More specifically, the range of motion of the sample block mechanism is between the rear end of the table 11 and the support frame 2. After selecting the test mode, the blocking rod 71 is moved to the set position through the shifting device, and then the cigarette package is placed on the table 11 just against the blocking rod 71 to proceed to the next step of the test. After pressing the test button, the blocking rod 71 will move back to avoid blocking the bending arm 5.

[0038] As an optional embodiment of the present application, the displacement device includes a screw rod 73 and a moving rod 72 , the lower end of the moving rod 72 is arranged on the screw rod 73 , and the upper end of the moving rod 72 is connected to the blocking rod 71 .

[0042] As an optional embodiment of the present application, the base 1 is also provided with a power switch, a power socket, an antenna, a connection serial port and a WIFI network module.

[0043] As an optional embodiment of the present application, Figure 3 , 4 As shown, a dustproof cover shell 10 is arranged on the top of the support frame 2.

[0044] As an optional embodiment of the present application, Figure 3 , 4 As shown, the bottom of the base 1 is also provided with a foot.

[0045] The operation process of the cigarette packaging indentation performance tester is as follows: Turn on the instrument and perform calibration and parameter setting. After selecting the test mode, the sample block mechanism operates, the baffle 71 moves to the set position, and then the cigarette package is placed on the table 11 just against the baffle 71. After pressing the test button, the baffle 71 will move back to its position. At this time, the sample pressing mechanism starts to operate, and the first sample pressing mechanism 3 and the second sample pressing mechanism 4 are pressed on the cigarette package, and the second sample pressing mechanism 4 is at the front end close to the indentation of the cigarette package. Then the folding mechanism starts to operate, and the bending arm 5 starts to flip upward. When the part of the cigarette package located at the rear end of the indentation is folded 90° along the indentation, the second sample pressing mechanism 4 resets upward, and the bending arm 5 continues to fold the cigarette package forward, and a folding is completed.

[0046] After folding is completed, the bending arm 5 is reset, the cigarette package indentation reset mechanism on the first pressing mechanism 3 starts to operate, the push plate 33 is extended under the action of the cylinder to flatten the cigarette package and then reset it, the second pressing mechanism 4 is pressed down again, and then the first folding process is repeated, thereby achieving multiple folding.

[0047] During the test, the instrument collects test data through the operation panel 9 or remote connection, including the change of indentation depth, and the rupture area of ​​the ink layer and the aluminum layer.

[0048] The following is an example of experimental data designed for a cigarette package indentation performance tester in order to evaluate its performance and support the description of the effects of the invention: 1. Purpose of the experiment Test the indentation and folding resistance of different types of cigarette packaging (soft pack, hard pack) to evaluate the integrity of the ink layer and aluminum layer after multiple folding and the durability of the indentation.

[0049] 2. Experimental parameters Sample specifications: Soft packing: paper, thickness 80g / m²; Hard pack: paper, thickness 120g / m², with aluminum film on the surface; Folding angle: 90° and 180°; Folding times: 50 times, 100 times, 200 times; Test environment: temperature 23°C, humidity 50%RH.

[0050] 4. Evaluation indicators: Integrity of ink layer (expressed as percentage of ruptured area); Aluminum layer integrity (expressed as percentage of cracked area); Change in indentation depth (the difference between the initial indentation depth and the depth after folding, in mm).

[0051] 5. Experimental data Packaging Type Folding Angle Fold times Ink layer rupture area (%) Aluminum layer crack area (%) Indentation depth change (mm) Soft Case 90° 50 times 0 - 0.01 Soft Case 90° 100 times 1.2 - 0.02 Soft Case 180° 200 times 3.5 - 0.05 Hard Pack 90° 50 times 0.3 0.5 0.01 Hard Pack 90° 100 times 1.8 2.0 0.03 Hard Pack 180° 200 times 5.0 6.5 0.08 6. Data Analysis 1) Cracking of ink layer and aluminum layer: The ink layer of the soft package has a smaller rupture area after multiple folding, showing good folding resistance. The rupture area of ​​the ink layer and aluminum layer of the hard package increases significantly with the increase of folding times and angles, especially when folded at 180°.

[0052] 2) Change of indentation depth: The change in indentation depth of soft and hard packages increases linearly with the number of folding times, but the change in hard packages is slightly higher, indicating that hard package materials are more easily affected by folding.

[0053] 3) Influence of folding angle: Under the same folding number, the degree of rupture of 180° folding is significantly higher than that of 90°, indicating that a larger folding angle will aggravate the stress concentration of the material.

[0054] 7. Conclusion Experimental data show that the cigarette packaging indentation performance tester can effectively evaluate the folding resistance and indentation strength of packaging materials, and the test results provide an important reference for the optimization design of packaging materials. Due to its aluminum film structure, hard packaging has higher requirements for the indentation process and folding process; while soft packaging shows better folding resistance.
