Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a device for detecting the sealing performance of cigarette box packaging. Background Technology

[0002] Cigarette packs are the smallest unit of packaging commonly used for cigarettes. During production, a plastic sealing sleeve is wrapped around the cigarette pack to improve its airtightness. The airtightness of the cigarette pack significantly affects the storage period of cigarettes. Good airtightness effectively prevents the loss of aroma from cigarettes after long-term storage and reduces the impact of the external environment on the moisture content of the cigarettes, lowering the risk of mold growth. Currently, the tobacco industry tests the airtightness of cigarette packs by fully immersing them in water and manually observing for air bubbles to determine if there is a leak. However, this method is not only inefficient, but also limited by the observer's perspective. The observation angle needs to be constantly adjusted to ensure comprehensive observation, significantly increasing the observation time. Furthermore, the accuracy of the test results decreases as the inspector's attention wanes.

[0003] Therefore, there is an urgent need for a device to test the sealing performance of cigarette box packaging in order to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cigarette box packaging sealing detection device that can automatically identify whether there are air bubbles in the sealed container, and can identify and count the air bubbles, thereby quickly determining whether there is air leakage in the cigarette box and determining the location of the leak, thus ensuring the accuracy of the detection results.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A device for detecting the sealing performance of cigarette box packaging, comprising:

[0007] The base is positioned at the support point;

[0008] A sealed container is placed on the base. The sealed container contains test water. When the cigarette box is completely immersed in the test water, the leaking defective product will form bubbles in the test water. The sealed container is a transparent container.

[0009] The detection mechanism is disposed on the base and located on one side of the sealed container. The detection mechanism is configured to monitor whether the air bubbles exist in the sealed container and the location where the air bubbles are generated, so as to determine whether the cigarette box is a defective product and to determine the location of the air leakage of the defective product.

[0010] Preferably, the detection mechanism includes a crossbar and multiple detection components. The crossbar is disposed on one side of the base, and the multiple detection components are spaced apart along the length of the crossbar. The detection components are used to monitor whether the air bubble exists in the sealed container and the location where the air bubble is generated.

[0011] Preferably, the detection assembly includes a detection element, a locking rod, and two spaced-apart support blocks, wherein the locking rod can lock the detection element between the two support blocks.

[0012] Preferably, the detection assembly further includes an adjustment knob disposed on the outside of one of the support blocks and connected to the locking rod, and the locking rod can rotate when the adjustment knob is rotated.

[0013] Preferably, the detection assembly further includes two clamping blocks, which are disposed on both sides of the detection element. When the adjustment knob is rotated, the two clamping blocks can move simultaneously toward or away from the detection element, so as to clamp or release the detection element.

[0014] Preferably, the detection assembly consists of three parts, with the middle detection element facing the central axis of the sealed container, and the distance between the two detection elements at both ends not exceeding the diameter of the sealed container.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 2 As shown, this utility model provides a cigarette box packaging sealing test device, which includes a base 10, a sealing container 20, and a test mechanism 30. The base 10 is positioned in a supporting position. The sealing container 20 is placed on the base 10 and contains test water. When the cigarette box is completely immersed in the test water, leaking defective products will form bubbles in the test water. The sealing container 20 is a transparent container. The test mechanism 30 is placed on the base 10 and located on one side of the sealing container 20. The test mechanism 30 is configured to monitor whether there are bubbles in the sealing container 20 and the location where the bubbles are generated, so as to determine whether the cigarette box is a defective product and to determine the location of the leak in the defective product.

[0034] After immersing the cigarette box in the test water in the sealed container 20, if the cigarette box is a defective product with a leak, water will enter at the leak point, and bubbles will be generated in the test water. Since the sealed container 20 is transparent, the bubbles inside can be observed from the outside. The testing mechanism 30 can monitor the presence of bubbles in the test water in real time. If bubbles are continuously rising upwards, it proves that the cigarette box is a defective product. The testing mechanism 30 can also determine the location of the leak based on the position of the bubbles. The entire testing process requires no manual intervention; the testing mechanism 30 can automatically complete the testing, improving the accuracy of the test results.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, the detection mechanism 30 includes a crossbar 31 and multiple detection components 32. The crossbar 31 is disposed on one side of the base 10, and the multiple detection components 32 are spaced apart along the length of the crossbar 31. The detection components 32 are used to monitor whether air bubbles exist in the sealed container 20 and the location where the air bubbles are generated. In this structure, multiple detection components 32 can simultaneously monitor air bubbles in the sealed container 20, thereby increasing the number of monitoring points, ensuring comprehensive monitoring, and avoiding omissions. In addition, by setting the crossbar 31, not only can multiple detection components 32 be integrated onto the crossbar 31, but the entire detection mechanism 30 can also be easily fixed to the base 10, greatly improving the ease of installation.

[0036] Preferably, such as Figure 1 and Figure 2 As shown, the detection assembly 32 includes a detection element 321, a locking rod 322, and two spaced-apart support blocks 323. The locking rod 322 can lock the detection element 321 between the two support blocks 323. This arrangement can further improve the ease of installation of the detection element 321. The detection element 321 in each detection assembly 32 can be separated by the support blocks 323, which facilitates installation and positioning.

[0037] In addition, such as Figure 1 and Figure 2 As shown, the detection assembly 32 also includes an adjustment knob 324, which is located on the outside of a support block 323 and connected to a locking rod 322. Rotating the adjustment knob 324 allows the locking rod 322 to rotate. This arrangement allows the angle of the detection element 321 to be adjusted via the adjustment knob 324, enabling the detection element 321 to be adjusted to a convenient angle for monitoring, thereby improving the accuracy and convenience of monitoring.

[0038] Specifically, such as Figure 1 and Figure 2As shown, the detection assembly 32 also includes clamping blocks 325. Two clamping blocks 325 are positioned on both sides of the detection element 321. When the adjusting knob 324 is rotated, the two clamping blocks 325 can simultaneously move towards or away from the detection element 321 to clamp or release it. When the adjusting knob 324 is turned, the locking rod 322 rotates together, creating relative movement between the locking rod 322 and the clamping blocks 325. Due to the threaded action, the clamping blocks 325 can move towards or away from the detection element 321. When the clamping blocks 325 move away from the detection element 321, the sides of the detection element 321 are no longer clamped. At this point, the angle of the detection element 321 can be adjusted. After adjusting the angle, continue turning the adjusting knob 324 to re-clamp the detection element 321 with the two clamping blocks 325, fixing the detection element 321 at a preset angle. The structure is simple, significantly improving ease of use and user experience.

[0039] It should be noted that in this embodiment, the detection component 32 is provided with three components, with the middle detection element 321 facing the central axis of the sealed container 20, and the distance between the two detection elements 321 at both ends not exceeding the diameter of the sealed container 20. In this structure, the detection element 321 in the middle position can monitor whether air bubbles are generated in the middle of the sealed container 20, and the two detection elements 321 at both ends can monitor whether air bubbles are generated on both sides, thereby enabling comprehensive monitoring of the interior of the sealed container 20, avoiding any omissions, and fully ensuring the overall monitoring accuracy.

[0040] Furthermore, the inspection component 321 is an adjustable smart camera. It not only captures high-resolution images, but the three adjustable smart cameras can automatically allocate shooting areas, dividing the sealed container 20 into three independent RPI regions for monitoring, reducing computational redundancy. They can also perform collaborative tracking; when a bubble enters an adjacent monitoring area, SIFT feature matching is used to correlate the trajectory, solving the problem of bubble loss across regions and reducing single-point errors. This achieves full coverage of the internal space of the sealed container 20, enabling efficient bubble identification and counting. After image acquisition, the data is transmitted to an industrial computer in the analysis center for data analysis to determine whether the sealing performance is up to standard. The original image data, intermediate processing results, and final calculation results are stored in a database. This database storage facilitates subsequent data retrieval, analysis, and traceability, and provides historical data support for project optimization and algorithm improvement, helping to continuously improve project performance and accuracy. It avoids interference from manual judgment, effectively improving the accuracy of inspection results and the sealing quality of the product.

[0041] like Figure 1As shown, the sealed container 20 includes a cover 21 and a cylinder 22. The cover 21 is detachably mounted on the top of the cylinder 22 to close or open the opening of the cylinder 22. The separate and detachable structure of the cover 21 and the cylinder 22 can significantly improve the convenience of taking out and putting in cigarette boxes, and also facilitate the replacement of the test water inside the cylinder 22.

[0042] Preferably, such as Figure 1 As shown, a first supplementary lighting band 23 is provided at the bottom of the cylinder 22, and the first supplementary lighting band 23 is arranged around the outer periphery of the cylinder 22. In this structure, the first supplementary lighting band 23 can provide supplementary lighting to the cylinder 22 from the bottom. Since the cylinder 22 is made of transparent material, light can smoothly enter the interior of the cylinder 22, thereby providing good illumination conditions for the water being detected and ensuring that the detection element 321 can capture the generation of bubbles in a timely manner. Because the first supplementary lighting band 23 is annular, it can significantly improve the supplementary lighting effect.

[0043] In addition, such as Figure 1 As shown, a second supplementary lighting strip 24 is provided at one end of the cylinder 22 near the cover 21. The second supplementary lighting strip 24 is arranged around the outer periphery of the cylinder 22 and is lower than the height of the cover 21. The second supplementary lighting strip 24 can cooperate with the first supplementary lighting strip 23 to maximize the illumination effect. At the same time, the supplementary lighting strips at both ends will not affect the detection element 321 from capturing bubbles. Furthermore, since the height of the second supplementary lighting strip 24 is slightly lower than the cover 21, it will not interfere with the second supplementary lighting strip 24 when the cover 21 is removed or placed, thus improving ease of use.

[0044] like Figure 1 As shown, a switch 25 is provided on the side of the cylinder 22 opposite to the detection mechanism 30. The switch 25 is used to turn the first supplementary lighting strip 23 and the second supplementary lighting strip 24 on and off. By setting the switch 25, the on / off of the first supplementary lighting strip 23 and the second supplementary lighting strip 24 can be controlled with one button, avoiding the waste of resources caused by continuous illumination. At the same time, the position of the switch 25 is not only convenient to operate, but also will not interfere with the detection mechanism 30, which greatly improves the convenience of operation.

[0045] In summary, the cigarette box packaging sealing detection device in this embodiment can automatically identify whether there are air bubbles inside the sealed container 20, and can identify and count the air bubbles, thereby quickly determining whether there is air leakage in the cigarette box and determining the location of the leak, thus ensuring the accuracy of the detection results.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
