Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a mold for verifying the detection depth of a cigarette pack missing pack detector. Background Technology

[0002] The missing pack detector is a device fixed in the tobacco bridge channel to detect whether there are missing packs inside the tobacco sticks, ensuring that tobacco sticks without missing packs can enter the next process.

[0003] The GDX1 and GDX2 packaging machines commonly used in China have high sensitivity and stable detection of missing packages. However, due to long-term use and some unpredictable external influences, their detection depth may change, resulting in the inability to detect missing packages. Therefore, after a period of use, it is necessary to verify the detection depth of the missing package detector. If it is found that the detection depth is insufficient and the missing package is not detected, the detection depth of the missing package detector needs to be corrected.

[0004] In existing technologies, genuine cigarette pack detectors are used to determine the accuracy of their detection. However, the presence or absence of packs inside genuine cigarette packs is uncertain, meaning the verification results are not entirely reliable. Furthermore, the cigarette packs need to be disassembled to check the results after verification. This process is repeated multiple times (verification is typically required before the machine starts operation each day), resulting in a waste of cigarette packs.

[0005] Therefore, there is an urgent need to design a mold and a cigarette production line to verify the detection depth of the cigarette pack missing detector in order to solve the above problems. Utility Model Content

[0006] One objective of this invention is to provide a mold for verifying the detection depth of a cigarette pack missing detector, which can accurately determine the detection accuracy of the cigarette pack detector, avoid the use of the cigarette pack detector when the detection depth is inaccurate, causing missing cigarette packs to flow into subsequent processes, and reduce cigarette pack waste.

[0007] Another objective of this invention is to provide a cigarette production line that can accurately detect cigarette packs with missing packs, thereby preventing these packs from entering the market.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] The mold used to verify the detection depth of the cigarette pack missing detector includes:

[0010] The cigarette stick mold has several cigarette pack spaces on its front side, and these spaces are arranged in a matrix.

[0011] Several cigarette pack molds are set up one-to-one with the aforementioned cigarette pack spaces, and each of the aforementioned cigarette pack molds can be placed in or taken out of the corresponding aforementioned cigarette pack space.

[0012] As an optional solution, the materials of the above-mentioned cigarette stick mold and the above-mentioned cigarette pack mold are both ethylene-vinyl acetate copolymer.

[0013] As an alternative, there are ten cigarette pack spaces, arranged in an M-row N-column matrix, where M < N.

[0014] As an alternative, M=2, N=5.

[0015] As an alternative, in the M cigarette pack spaces in the same column, the interval between two adjacent cigarette pack spaces is L1, where 5mm≤L1≤10mm.

[0016] As an alternative, among the N cigarette pack spaces in the same row, the interval between two adjacent cigarette pack spaces is L2, where 3mm≤L2≤5mm.

[0017] As an optional solution, in the cigarette pack space adjacent to the upper or lower side of the cigarette stick mold, the distance between the cigarette pack space and the corresponding upper or lower side of the cigarette stick mold is L3, where 5mm≤L3≤10mm.

[0018] As an optional solution, in the cigarette pack space adjacent to the left or right side of the cigarette stick mold, the distance between the cigarette pack space and the corresponding left or right side of the cigarette stick mold is L4, where 5mm≤L4≤10mm.

[0019] As an alternative, the space in the cigarette pack can be a through hole running from front to back; or

[0020] The space in the cigarette pack is a recess.

[0021] The cigarette production line includes the molds used to verify the detection depth of the cigarette pack missing detector.

[0022] The beneficial effects of this utility model are as follows:

[0023] This invention provides a mold for verifying the detection depth of a cigarette pack missing detector. By setting up a cigarette pack mold and several cigarette bag molds, the detection depth of the missing cigarette pack detector is verified instead of using actual cigarette packs. During verification, assuming the total number of cigarette bag molds is A, then A verifications are sufficient to completely verify whether the missing cigarette pack detector is working properly. Specifically, the radiation emitted by the missing cigarette pack detector enters from the front of the cigarette pack mold. One cigarette bag space is left empty of a cigarette bag mold, while the remaining spaces are filled with cigarette bag molds. One verification is performed. If the missing cigarette pack detector detects a missing pack, it means that the radiation is insufficient in the cigarette pack space where no cigarette bag mold is placed. The detection depth of the empty cigarette pack space is qualified. In verification A, the empty cigarette pack space settings are alternated each time until after verification A, each cigarette pack space has been independently verified once, indicating that the detection depth of the missing pack detector is qualified in each cigarette pack space. Conversely, if the missing pack detector does not report a missing pack signal, it means that the detection depth at the corresponding cigarette pack space position is unqualified and needs to be adjusted. The above mold replaces the real cigarette pack to verify the detection depth of the missing pack detector, and during verification, the operator can accurately know the problem position of the missing pack detector's ray, which is convenient for subsequent correction.

[0024] This invention also provides a cigarette production line, including the mold for verifying the detection depth of the missing pack detector. This cigarette production line can accurately detect missing packs of cigarettes, preventing them from entering the market. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] A missing pack detector is a device fixed in the cigarette bridge channel to detect whether cigarette packs are missing from the inside of the cigarette packs, ensuring that cigarette packs without missing packs proceed to the next process. Domestically used GDX1 and GDX2 packaging machines have high sensitivity and stable missing pack detection; however, due to long-term use and unpredictable external influences, their detection depth requires frequent adjustments, necessitating sensitivity calibration. In existing technologies, the accuracy of cigarette pack detectors is assessed using genuine cigarette packs. However, the missing pack status within genuine cigarette packs is uncertain—they may or may not contain missing packs—making the verification results not entirely reliable.

[0034] To address the aforementioned issues, this embodiment provides a mold for verifying the detection depth of a cigarette pack missing item detector, hereinafter referred to as the mold. Figures 1-2 As shown ( Figure 1Only one cigarette pack mold 20 is shown. The mold includes a cigarette stick mold 10 and several cigarette pack molds 20. Several cigarette pack spaces 11 are opened on the front side of the cigarette stick mold 10. The several cigarette pack spaces 11 are arranged in a matrix. Several cigarette pack molds 20 are set one-to-one with the cigarette pack spaces 11. Each cigarette pack mold 20 can be placed in or taken out of the corresponding cigarette pack space 11.

[0035] The aforementioned mold, by setting up a cigarette stick mold 10 and several cigarette pack molds 20, replaces the existing real cigarette sticks to verify the detection depth of the missing pack detector. During verification, assuming the total number of cigarette pack molds 20 is A, then A verifications are sufficient to completely verify whether the missing pack detector is working properly. Specifically, the radiation emitted by the missing pack detector enters from the front of the cigarette stick mold 10. One cigarette pack space 11 is not filled with a cigarette pack mold 20, while the remaining cigarette pack spaces 11 are filled with cigarette pack molds 20. One verification is performed. If the missing pack detector verifies a missing pack, it means that the radiation is insufficient in the cigarette pack space 11 where no cigarette pack mold 20 is placed. The detection depth at the location is qualified. In verification A, the setting of the empty cigarette pack space 11 is changed alternately each time until after verification A, each cigarette pack space 11 has been independently verified once, indicating that the detection depth of the missing pack detector is qualified in each cigarette pack space 11. Conversely, if the missing pack detector does not report a missing pack signal, it means that the detection depth at the corresponding cigarette pack space 11 is unqualified and needs to be adjusted. The above mold replaces the real cigarette pack to verify the detection depth of the missing pack detector. During verification, the operator can accurately know the problem location of the missing pack detector's ray, which is convenient for subsequent correction.

[0036] In this embodiment, as Figure 2 As shown, there are ten tobacco pack spaces 11, arranged in an M x N matrix, where M < N. Specifically, M = 2 and N = 5. This arrangement of the ten tobacco pack spaces 11 simulates the arrangement of existing conventional cigarette packs.

[0037] In other embodiments, the number of cigarette pack spaces 11 can be adjusted according to the arrangement of real cigarette packs to be simulated, and is not limited here.

[0038] Optionally, both the cigarette stick mold 10 and the cigarette pack mold 20 are made of EVA (Ethylene Vinyl Acetate Copolymer). This material is commonly used in the processing and manufacturing of shoe soles. Using this material to manufacture the cigarette stick mold 10 and the cigarette pack mold 20 results in better toughness and impact resistance, extending the service life of the mold.

[0039] Optionally, in the M cigarette pack spaces 11 within the same column, the interval between two adjacent cigarette pack spaces 11 is L1, where 5mm ≤ L1 ≤ 10mm. Due to the properties of EVA material, L1 is chosen within this range to ensure sufficient strength of the partition walls in the cigarette pack spaces 11 during multiple takes-ups and drops. In this embodiment, since the side corresponding to the cigarette pack space 11 within the same column is relatively long, the frictional force experienced during cigarette pack take-ups and drops is greater; therefore, L1 is set relatively large, preferably 10mm.

[0040] Optionally, among the N cigarette pack spaces 11 in the same row, the interval between two adjacent cigarette pack spaces 11 is L2, where 3mm ≤ L2 ≤ 5mm. The thickness direction of the cigarette pack corresponding to the opposite side of the N cigarette pack spaces 11 in the same row is smaller, resulting in a smaller friction area between the cigarette pack and the sidewall where L2 is located. Therefore, the pulling force is smaller, and the strength of the sidewall where L2 is located can be slightly less than the strength of the sidewall where L1 is located. Therefore, L2 can be set slightly smaller than L1. Preferably, 5mm.

[0041] Optionally, in the tobacco pouch space 11 adjacent to the upper or lower side of the tobacco stick mold 10, the distance between the tobacco pouch space 11 and the corresponding upper or lower side of the tobacco stick mold 10 is L3, where 5mm ≤ L3 ≤ 10mm. And / or in the tobacco pouch space 11 adjacent to the left or right side of the tobacco stick mold 10, the distance between the tobacco pouch space 11 and the corresponding left or right side of the tobacco stick mold 10 is L4, where 5mm ≤ L4 ≤ 10mm. That is to say, the thickness of the outer ring of the tobacco stick mold 10 needs to be within this range, preferably 10mm, to ensure that the outer wall of the tobacco stick mold 10 has sufficient strength and is not easily damaged.

[0042] Optionally, such as Figure 2 As shown, the cigarette pack space 11 is a through hole running through the front and back directions, which facilitates the taking out and putting in the cigarette pack; or the cigarette pack space 11 is a groove, which prevents the cigarette pack from easily coming out of the through hole when the transfer mold is being used. Therefore, a through hole can be opened at the bottom of the groove to facilitate the removal of the cigarette pack.

[0043] This embodiment also provides a cigarette production line, including the mold described above for verifying the detection depth of the cigarette pack shortage detector. This cigarette production line can accurately detect cigarette packs with missing packs, preventing them from entering the market.

[0044] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments 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.
