Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a tax invoice pasting device. Background Technology

[0002] In the ZB45 packaging unit, the CH small box transparent packaging machine requires the tax stamp pasting process to be completed during the cigarette pack conveying process. In this process, the tax stamp needs to be precisely pasted onto the surface of the cigarette pack after being treated with adhesive. The cigarette pack then continues to be conveyed forward, passing through key components such as the transition bin and forming roller, and finally completing the transparent packaging process. However, in actual production, because the adhesive on the tax stamp cannot fully cure in a short time after application, the adhesion strength between the tax stamp and the surface of the cigarette pack is insufficient. As the cigarette pack moves forward with the conveyor mechanism, the tax stamp is easily lifted due to factors such as airflow disturbance, slight collisions between adjacent cigarette packs, or the tension of its own material. When a cigarette pack with a lifted tax stamp enters the transition bin, the edge of the lifted tax stamp is very likely to scratch the inner wall of the channel in the transition bin; and when the cigarette pack enters the forming roller, the edge of the forming roller needs to precisely fit with the surface of the cigarette pack to form the transparent paper, causing the lifted tax stamp to be scraped over by the edge of the forming roller. Both of these situations will cause the tax stamp to completely fall off the surface of the cigarette pack, thus causing the problem of missing tax stamps on cigarette packs. On the one hand, missing tax invoices directly cause cigarette products to fail to meet circulation compliance requirements, resulting in a significant drop in product qualification rate and increased costs for product rework or scrapping. On the other hand, detached tax invoices accumulate in the transition warehouse, forming wheels, and conveyor channels, which may cause equipment jamming and malfunctions, requiring frequent machine shutdowns, manual cleaning of detached tax invoices, and a comprehensive inspection of equipment operation. This not only interrupts the continuous production process and leads to a significant decrease in production efficiency, but also greatly increases the workload and time costs of manual maintenance, severely restricting the large-scale production of tobacco companies.

[0003] Therefore, there is an urgent need to develop a tax invoice pasting device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide a tax invoice bonding device to achieve rapid and secure bonding of tax invoices to cigarette packs, preventing tax invoices from falling off during transport, adapting to the structure and transport characteristics of CH small box transparent packaging machines, improving production efficiency and reducing labor costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tax stamp pasting device includes at least one pasting mechanism. The pasting mechanism includes a mounting bracket, a rotating shaft, a roller, a mounting base, an adjusting component, and an elastic element. The mounting bracket is connected to the upper side of the upper cover plate of the cigarette pack conveying channel. The adjusting component is slidably connected to the mounting bracket in the vertical direction and is fixedly connected to the mounting base. The elastic element is disposed between the mounting base and the mounting bracket. The axis of the rotating shaft extends horizontally and is perpendicular to the cigarette pack conveying direction. The rotating shaft is connected to the mounting base. The roller is rotatably sleeved on the rotating shaft and is located on the movement path of the tax stamp. The upper cover plate has a rolling groove for avoiding the roller, so that the roller can roll the tax stamp.

[0007] In some optional embodiments, the adjusting assembly includes an adjusting screw and an adjusting nut, the mounting bracket has a mounting hole extending in a vertical direction, the adjusting screw passes through the mounting hole and the lower end of the adjusting screw is connected to the mounting base, and the adjusting nut is located above the mounting bracket and is threadedly engaged with the adjusting screw.

[0008] In some optional embodiments, the thread specification of the adjusting screw is M6 to M8; and / or,

[0009] The thread length of the adjusting screw is 30~50mm.

[0010] In some alternative embodiments, the elastic element is sleeved around the adjusting screw.

[0011] In some optional embodiments, the elastic modulus of the elastic element is 5~15 N / mm.

[0012] In some optional embodiments, the mounting bracket has a guide groove extending in a vertical direction, and the mounting base slides in conjunction with the guide groove.

[0013] In some alternative embodiments, the roller is rotatably connected to the shaft via a bearing.

[0014] In some alternative embodiments, the roller is made of rubber or nylon; and / or,

[0015] The surface hardness of the roller is Shore 60~80HS-D.

[0016] In some alternative embodiments, the mounting bracket is bolted to the top cover.

[0017] In some alternative embodiments, the number of bonding mechanisms is at least two, and the at least two bonding mechanisms are arranged at even intervals along the conveying direction of the cigarette pack.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a tax stamp pasting device, including at least one pasting mechanism. The pasting mechanism includes a mounting bracket, a rotating shaft, a roller, a mounting base, an adjusting component, and an elastic element. The mounting bracket is connected to the upper side of the upper cover plate of the cigarette pack conveying channel. The adjusting component is slidably connected to the mounting bracket in the vertical direction and is fixedly connected to the mounting base. The elastic element is disposed between the mounting base and the mounting bracket. The axis of the rotating shaft extends in the horizontal direction and is perpendicular to the cigarette pack conveying direction. The rotating shaft is connected to the mounting base. The roller is rotatably sleeved on the rotating shaft and is located on the movement path of the tax stamp. The upper cover plate has a rolling groove for avoiding the roller. The lower end of the roller can pass through the rolling groove and contact the cigarette pack and the tax stamp on its surface so that the roller can roll the tax stamp. The elastic element is placed between the mounting base and the mounting bracket, giving the mounting base a downward tendency, so that the roller contacts the surface of the cigarette pack and the tax invoice. When the cigarette pack passes the roller, the roller moves passively with the cigarette pack, rolling the tax invoice, thereby preventing the tax invoice from lifting, accelerating the curing of the adhesive, and enhancing the adhesion between the tax invoice and the cigarette pack.

[0020] The adjustment component is slidably connected to the mounting bracket in the vertical direction. The elastic element is set between the mounting base and the mounting bracket. When the roller is subjected to excessive pressure, the mounting base can squeeze the elastic element to move upward, so that the roller can adaptively adjust its height according to the slight changes in the thickness of the cigarette pack, thereby ensuring stable bonding pressure.

[0021] By adopting the tax invoice pasting device of this embodiment, the problem of difficulty in mechanizing tax invoice pasting and reinforcement is solved, and the tax invoice is quickly and firmly pasted onto the cigarette pack, which can prevent the tax invoice from falling off during transportation; and it is adapted to the structure and transportation characteristics of the CH small box transparent packaging machine, improving production efficiency and reducing labor costs.

[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 this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0032] In this invention, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0033] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0034] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0035] In this utility model, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely 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.

It should also be understood that directional terms such as "upper side," "lower side," "left side," "right side," "front side," and "rear side" not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" of the first feature and the second feature include the first feature being directly above, to the upper left, to the upper right, to the upper front, and to the upper rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0036] In the process of pasting tax invoices 200, due to the slight difference in thickness of each cigarette pack 100, it is difficult for mechanized equipment to achieve continuous and stable pressure-assisted pasting. Currently, manual temporary pressing is usually used for reinforcement, which is inefficient and the uneven pressure of manual pressing can easily lead to new problems such as wrinkles and positional displacement of the tax invoices 200, further increasing labor costs, product rework or scrap costs.

[0037] To solve the above problems, such as Figures 1-3 As shown, this embodiment provides a tax invoice pasting device, including at least one pasting mechanism 1. The pasting mechanism 1 includes a mounting bracket 11, a rotating shaft 12, a roller 13, a mounting base 14, an adjusting component 15, and an elastic element 16. The mounting bracket 11 is connected to the upper side of the upper cover plate 300 of the cigarette pack conveying channel. The adjusting component 15 is slidably connected to the mounting bracket 11 in the vertical direction, and the adjusting component 15 is fixedly connected to the mounting base 14. The elastic element 16 is disposed between the mounting base 14 and the mounting bracket 11. Between the frames 11, the axis of the rotating shaft 12 extends horizontally and is perpendicular to the conveying direction of the cigarette pack 100. The rotating shaft 12 is connected to the mounting base 14. The roller 13 is rotatably sleeved on the rotating shaft 12 and is located on the moving path of the tax invoice 200. The upper cover plate 300 has a rolling groove 310 for avoiding the roller 13. The lower end of the roller 13 can pass through the rolling groove 310 and contact the cigarette pack 100 and the tax invoice 200 on its surface so that the roller 13 can roll the tax invoice 200.

[0038] The elastic element 16 is disposed between the mounting base 14 and the mounting bracket 11, so that the mounting base 14 has a downward tendency, thereby causing the roller 13 to contact the surfaces of the cigarette pack 100 and the tax invoice 200. When the cigarette pack 100 passes the roller 13, the roller 13 rotates passively as the cigarette pack 100 moves, rolling the tax invoice 200, thereby preventing the tax invoice 200 from lifting, accelerating the curing of the adhesive, and enhancing the adhesion between the tax invoice 200 and the cigarette pack 100.

[0039] The adjusting component 15 is slidably connected to the mounting bracket 11 in the vertical direction. The elastic element 16 is disposed between the mounting base 14 and the mounting bracket 11. When the roller 13 is subjected to excessive pressure, the mounting base 14 can squeeze the elastic element 16 to move upward, so that the roller 13 can adaptively adjust its height according to the slight change in the thickness of the cigarette pack 100, thereby ensuring stable bonding pressure.

[0040] By adopting the tax invoice pasting device of this embodiment, the problem of difficulty in mechanizing the pasting and reinforcement of tax invoices 200 is solved, realizing the rapid and firm pasting of tax invoices 200 and cigarette packs 100, which can prevent tax invoices 200 from falling off during transportation; and it is fully compatible with the existing cigarette pack 100 conveying path, spatial layout and conveying speed of the CH small box transparent packaging machine in the ZB45 packaging unit. Installation and debugging can be completed without large-scale disassembly and modification of the original equipment, which can reduce equipment modification investment, improve the practicality and promotion value of the device, meet the needs of tobacco companies for large-scale and automated production, improve production efficiency and reduce labor costs.

[0041] It should be noted that in actual production, the thickness of different models of cigarette packs 100 varies significantly, resulting in changes in the height of the tax invoice 200. Furthermore, the type of adhesive, the material, and the thickness of the tax invoice 200 all affect the required bonding pressure. For example, thin tax invoices 200 require less pressure to avoid wrinkles, while thicker tax invoices 200 require slightly more pressure to ensure a firm bond. Thin adhesives require less pressure to prevent overflow, while thick adhesives require more pressure to ensure full adhesion between the tax invoice 200 and the cigarette pack 100. Therefore, the adjustment component 15 in this embodiment includes an adjustment screw 151 and an adjustment nut 152. The mounting bracket 11 has a mounting hole extending vertically. The adjustment screw 151 passes through the mounting hole, and its lower end is connected to the mounting base 14. The adjustment nut 152 is located above the mounting bracket 11 and is threaded into the adjustment screw 151. Depending on the specifications of the cigarette pack 100, the thickness and material of the tax stamp 200, and the type of adhesive, the operator can adjust the height of the roller 13 by turning the adjusting nut 152, thereby adjusting the bonding pressure applied by the roller 13 to the tax stamp 200 through the mounting base 14. This adapts to different production conditions and significantly improves the versatility of the tax stamp bonding device.

[0042] In some optional embodiments, the thread specification of the adjusting screw 151 is M6~M8, and its pitch range is 0.5~1.25mm, so that the adjustment accuracy can reach the 0.1N level, which can cover most scenarios from "fine adjustment" to "fast adjustment", avoiding insufficient accuracy or low efficiency caused by excessively large or small pitch; and it has sufficient axial stiffness and vibration resistance, which can prevent deformation under force or dynamic displacement from destroying the accuracy and ensure long-term stable adjustment effect.

[0043] In some optional embodiments, the thread length of the adjusting screw 151 is 30~50mm, so that the rolling height adjustment range of the roller 13 is sufficient to meet the tax invoice 200 pasting requirements of most cigarette packs 100 in existing production scenarios.

[0044] In some optional embodiments, the elastic element 16 is circumferentially fitted onto the adjusting screw 151, providing a uniform and stable elastic force to the mounting base 14, ensuring balanced force distribution on the mounting base 14 and providing a stable and reliable support foundation for the roller 13. Furthermore, the adjusting screw 151 guides and limits the compression of the elastic element 16, preventing it from bending under pressure and affecting the rolling effect, thus improving the reliability of the tax invoice bonding device.

[0045] In this embodiment, the elastic element 16 is a spring, which has a simple structure, is easy to obtain, and has a low cost. Optionally, the elastic element 16 may include, but is not limited to, rubber tubing or air springs, and is not limited here.

[0046] In some optional embodiments, the elastic element 16 has an elastic coefficient of 5~15N / mm. The elastic element 16 works in conjunction with the adjustment component 15 to precisely adjust the pressure of the roller 13 according to the specifications of the cigarette pack 100, the thickness and material of the tax invoice 200, and the type of adhesive, so that the pressure adjustment range of the roller 13 reaches 0.5-5N, adapting to different production conditions.

[0047] like Figure 2 As shown, in some optional embodiments, the mounting bracket 11 has a guide groove 111 extending in the vertical direction. The mounting seat 14 is slidably engaged with the guide groove 111. The guide groove 111 provides guidance for the vertical movement of the mounting seat 14, which helps to ensure that the mounting seat 14 rises and falls smoothly, thereby ensuring that the pressure applied by the roller 13 to the tax invoice 200 is balanced and stable.

[0048] Specifically, the mounting base 14 and the guide groove 111 are fitted with a clearance to ensure that the mounting base 14 can be raised and lowered smoothly without jamming.

[0049] Both the mounting base 14 and the mounting bracket 11 are made of metal, which has good wear resistance and structural strength, and can provide a stable and reliable mounting foundation for the roller 13, which is conducive to improving the service life and reliability of the tax invoice bonding device.

[0050] In some optional embodiments, the roller 13 and the shaft 12 are rotatably connected by bearings, which helps to improve the smoothness of the roller 13's rotation, thereby reducing the frictional resistance between the roller 13 and the cigarette pack 100 and tax invoice 200, avoiding damage to the cigarette pack 100 and tax invoice 200 due to excessive friction, and preventing obstruction to the conveying of the cigarette pack 100, thus ensuring the transportation efficiency of the cigarette pack 100.

[0051] In some optional embodiments, the mounting bracket 11 and the upper cover plate 300 are connected by bolts, which can facilitate the quick and easy assembly of the tax invoice pasting device and the CH small box transparent packaging machine, and is easy to disassemble and maintain, which is conducive to improving the practicality and promotion value of the tax invoice pasting device.

[0052] In this embodiment, the upper cover plate 300 and the mounting bracket 11 are respectively provided with threaded holes, and the bolt can be threaded into the threaded holes of both to achieve a fixed connection of the mounting bracket 11. Of course, in other embodiments, the mounting bracket 11 is provided with mounting holes, and the upper cover plate 300 is respectively provided with threaded holes. The bolt passes through the mounting holes and is threaded into the upper cover plate 300, which can also achieve a fixed connection of the mounting bracket 11. Optionally, the bolt can also pass through the upper cover plate 300 and the mounting bracket 11 in sequence and be threaded into a nut. The bolt is locked by the nut to further improve the connection stability and reliability between the mounting bracket 11 and the upper cover plate 300. This is not limited here.

[0053] The upper cover plate 300 has a countersunk hole for accommodating the bolt head, which allows the bolt head to be embedded in the hole and prevents it from protruding from the underside of the upper cover plate 300 and interfering with the movement of the cigarette pack 100.

[0054] In some optional embodiments, the roller 13 is made of rubber or nylon. Compared with hard materials such as metal or ceramic, rubber or nylon has lower hardness and the material itself has a certain elasticity and cushioning ability and appropriate friction. This can prevent damage to the cigarette pack 100 and tax invoice 200, and also prevent the roller 13 from slipping, thereby ensuring the adhesion strength between the tax invoice 200 and the cigarette pack 100.

[0055] Among them, the surface hardness of roller 13 is Shore 60~80HS-D, which can ensure effective compression of tax invoice 200 without damaging the surface of cigarette pack 100 or tax invoice 200, and ensure the adhesion effect of tax invoice 200; and has good wear resistance, which can meet the loss control of long-term continuous production.

[0056] Optionally, the diameter of roller 13 is 15~25mm. On the one hand, a diameter of roller 13 of not less than 15mm can increase the contact area between roller 13 and tax invoice 200 or cigarette pack 100, reduce the rotation speed of roller 13, and help improve the stability of rolling; on the other hand, a diameter of roller 13 of not more than 25mm can fit the compact space of the conveyor channel of CH small box transparent packaging machine and avoid the risk of interference.

[0057] In this embodiment, there is one bonding mechanism 1, which rolls the tax invoice 200 once to improve the bonding effect.

[0058] In other alternative embodiments, the number of bonding mechanisms 1 is at least two, and the at least two bonding mechanisms 1 are evenly spaced along the conveying direction of the cigarette pack 100, rolling the tax invoice 200 at least twice, thereby improving the bonding effect. It is readily understood that the number of bonding mechanisms 1 can be adaptively selected based on the length of the tax invoice 200 and the curing time of the adhesive. The longer the tax invoice 200 and the longer the adhesive curing time, the more bonding mechanisms 1 are needed, and the more times the tax invoice 200 is rolled, thereby improving the bonding effect.

[0059] It should be noted that, considering the length of the conveyor channel of the CH small box transparent packaging machine and the size of the roller 13, the number of bonding mechanisms 1 is no more than three.

[0060] 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.
