Description

Technical Field

[0001] The invention relates to the technical field of cigarette packaging, in particular to a processing device and a processing technology of color-changing window lining paper. Background Art

[0002] The inner lining paper of cigarette boxes is made of a composite of aluminum foil and inner lining paper. It is the most common type of paper in cigarette packaging boxes. It is mainly used for moisture-proof, anti-corrosion and fragrance preservation. Aluminum foil has high barrier properties to light, gas and water, and can effectively protect cigarettes from the influence of external natural factors.

[0003] At present, the existing cigarette boxes have anti-counterfeiting marks on the outside of the cigarette boxes. The existing anti-counterfeiting identification method is to identify by observing the anti-counterfeiting marks on the outside of the cigarette boxes. However, due to the increasingly rampant counterfeiting of recycled cigarette boxes in recent years, it is easy to pass off fake cigarettes as genuine ones, which leads to consumers only identifying the authenticity by observing the fake marks on the outside of the cigarette boxes, making it difficult to distinguish the authenticity of the cigarette products, causing losses to the rights and interests of consumers;

[0004] The Chinese patent announcement number (CN112572902B) "discloses a liner paper packaging machine, including a paper rack mechanism, a paper guide mechanism, a paper cutting mechanism, a feeding mechanism, a pushing mechanism, a bottom surface two long side forming mechanism, a turret forming mechanism, an end ear folding mechanism, and a top surface short side forming mechanism; the liner paper enters the bottom surface two long side forming mechanism to fold the bottom surface two long sides upward; the pushing mechanism pushes the product and the liner paper into the turret forming mechanism; the turret forming mechanism drives the material to rotate while the liner paper top is folded through the end ear folding mechanism and the top surface short side forming mechanism The folding and forming are completed by opening the surface; the present application can complete the lining paper packaging fully automatically and efficiently; wherein, the hob shaft assembly realizes one-way rotation for one circle through the one-way rotation limiting assembly, which can facilitate the installation and maintenance of the blade and effectively improve the installation and maintenance efficiency; in addition; the lining paper sealing action is completed by the turret forming mechanism, the end folding ear mechanism, and the top short side forming mechanism, and the structural design is reasonable; the degree of automation is high "The above patent documents, although they can efficiently complete the packaging and processing of the lining paper, are difficult to anti-counterfeit in the tobacco products, and are prone to counterfeiting of tobacco products to disrupt the market.

[0021] Preferably, a processing device and a processing technology of color-changing window lining paper include the following steps:

[0022] S1. The inner lining paper is conveyed from the guide roller a to the slide roller, and the inner lining paper is placed on the conveying roller to ensure that the inner lining paper is in contact with the load-bearing plate. The inner lining paper is printed with an anti-counterfeiting mark by the pressing unit.

[0024] S3. After completing the pressing of the anti-counterfeiting mark on the inner lining paper, add a sufficient amount of photosensitive ink into the ink cartridge through the feed tube to ensure that the ink-coating belt is in full contact with and absorbs the photosensitive ink in the ink cartridge. The servo motor drives the roller to rotate synchronously, and the meshing transmission between the teeth and the toothed grooves is used to make the ink-coating belt run. The scraper scrapes off the excess photosensitive ink on the surface of the ink-coating belt, and the photosensitive ink is applied to the inner lining paper through the ink-coating belt.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention adds a unique anti-counterfeiting mark on the inner lining paper of the cigarette box and uses photosensitive ink to paint on the inner lining paper. After purchasing tobacco products, consumers can carefully observe the anti-counterfeiting mark on the outside of the cigarette box and the anti-counterfeiting mark on the inner lining paper for detailed comparison. If any abnormality or inconsistency is found during the comparison process, consumers can preliminarily determine that the purchased tobacco products may be counterfeit or inferior products. In this way, consumers can take timely measures to avoid further economic losses and report the situation to relevant market supervision departments or consumer protection agencies. In this way, the legitimate rights and interests of consumers are effectively protected, and at the same time, a powerful means is provided in the market to stop and crack down on the sale of counterfeit cigarettes. The investment and application of this anti-counterfeiting technology not only improves consumers' identification ability, but also enhances the standardization and fairness of the entire market, so that both legal businesses and consumers can benefit from it.

[0027] (2) The present invention drives the tensioning roller to move upward synchronously during the downward movement of the gravure plate. The coordinated movement can be used to adjust the tension of the inner lining paper through the pushing action of the tensioning roller during the pressing process of the gravure plate, thereby ensuring that the inner lining paper can maintain an appropriate tension state during the pressing process, thereby effectively preventing the inner lining paper from wrinkling due to insufficient tension, ensuring that the inner lining paper remains flat during the gravure printing process, and avoiding quality problems that may occur when processing the inner lining paper. This not only improves the overall effect of printing on the inner lining paper, but also improves the quality of the product.

[0028] (3) The present invention drives the ink coating belt to operate through a servo motor. The ink coating belt is in close contact with the inner lining paper to ensure that the photosensitive ink can be evenly applied to the surface of the inner lining paper. The photosensitive ink contains special photosensitive color-changing materials. When the light and the observation angle change, the anti-counterfeiting mark on the inner lining paper will show a variety of colors such as red and green, green and blue, gold and silver, etc. The optical color contrast feature is very obvious, so that the anti-counterfeiting mark on the inner lining paper shows different colors at different observation angles, thereby greatly increasing the complexity and difficulty of anti-counterfeiting. The application of this technology effectively improves the anti-counterfeiting performance of the inner lining paper, further prevents counterfeit tobacco products from entering the market, and thus protects the rights and interests of consumers.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figure 1-Figure 9 The device for processing color-changing window lining paper shown in the figure includes: a casing 1 and a guide roller a2 rotatably connected to the casing 1, two guide rollers a2 are provided, and the two guide rollers a2 are vertically symmetrically distributed, the lining paper is wound between the two guide rollers a2, and a conveying roller 3 is rotatably connected to the casing 1, two conveying rollers 3 are provided, and the two conveying rollers 3 are distributed in parallel, and also includes a guide roller a4, which is rotatably connected to the casing 1, a pressing unit 5 is provided on the casing 1, and the pressing unit 5 is used to press the anti-counterfeiting mark on the lining paper, a tensioning component 6 matched with the pressing unit 5 is provided on the casing 1, and the tensioning component 6 is used to adjust the tensioning force when pressing the lining paper, and an inking unit 7 provided on the casing 1, and the inking unit 7 is used to apply photosensitive ink to the lining paper.

[0042] It should be noted that photosensitive ink is an existing product. The principle of photosensitive ink is mainly based on photochemical reaction. When the photosensitive ink is exposed to light of a specific wavelength, such as ultraviolet light, the photosensitive agent in the ink will absorb light energy and undergo a chemical reaction, causing the physical properties of the photosensitive ink to change. When the lining paper absorbs light, the photosensitive ink changes color, making it easier for consumers to identify the anti-counterfeiting mark on the lining paper.

[0043] In this scheme: a processing device and a processing technology of color-changing window lining paper include the following steps:

[0044] S1. The liner paper is conveyed from the guide roller a2 to the slide roller 9, and the liner paper is placed on the conveying roller 3 to ensure that the liner paper is in contact with the load-bearing plate 54. The anti-counterfeiting mark is printed on the liner paper by the pressing unit 5. The liner paper is conveyed between the ink coating belt 74 and the conveying roller 3, and the photosensitive ink is applied to the liner paper by the ink coating unit 7;

[0045] S2. The gravure plate 53 is driven downward by the cylinder 52, and the gravure plate 53 forms an anti-counterfeiting mark on the inner lining paper. When the gravure plate 53 moves downward, the toothed plate a62 is driven to move, and the toothed plate a62 is meshed with the spur gear 64 to rotate the shaft 63, and the spur gear 64 is meshed with the toothed plate b67 to drive the tensioning roller 66 to move upward when the gravure plate 53 moves downward, so as to increase the tension of the inner lining paper when the anti-counterfeiting mark is pressed on the inner lining paper;

[0046] S3. After completing the pressing of the anti-counterfeiting mark on the inner lining paper, add a sufficient amount of photosensitive ink into the ink cartridge 71 through the feed tube 72 to ensure that the ink-coating belt 74 is in full contact with and absorbs the photosensitive ink in the ink cartridge 71, and the roller 73 is driven by the servo motor 75 to rotate synchronously, and the ink-coating belt 74 is operated by the meshing transmission effect between the teeth 76 and the toothed grooves 77, and the scraper 78 scrapes off the excess photosensitive ink on the surface of the ink-coating belt 74, and the photosensitive ink is applied to the inner lining paper through the ink-coating belt 74.

[0047] Further Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, it is worth to explain in detail that the pressing unit 5 includes a mounting plate 51, the mounting plate 51 is fixed on the housing 1, and a cylinder 52 is fixed on the mounting plate 51, and a gravure plate 53 is fixed on the output end of the cylinder 52, and the anti-counterfeiting mark is pressed on the lining paper through the gravure plate 53, and a bearing plate 54 is fixed on the housing 1, and the bearing plate 54 is located directly below the gravure plate 53;

[0048] It should be noted that the inner lining paper is pressed by the gravure plate 53 to form a concave anti-counterfeiting mark on the inner lining paper, and the anti-counterfeiting mark is printed by gravure printing, which is a prior art to achieve accurate printing of the anti-counterfeiting mark on the inner lining paper. This is a conventional setting in the art, so it will not be described in detail here.

[0049] It should also be noted that by adding anti-counterfeiting marks on the lining paper and using photosensitive ink to paint it, consumers can compare the anti-counterfeiting marks on the outside of the cigarette box and the anti-counterfeiting marks on the lining paper after purchasing tobacco products. If they find any abnormalities, they can judge that the tobacco products may be counterfeit, so they can stop the loss in time and report the situation to the relevant departments. This can reasonably protect the consumer rights and interests, is suitable for use in the market, and can effectively stop the sale of counterfeit cigarettes.

[0050] Further Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, it is worth specifically explaining that the tensioning assembly 6 includes a connecting plate 61, the connecting plate 61 fixed on the gravure plate 53, two toothed plates a62 fixed on the connecting plate 61, a rotating shaft 63 rotatably connected to the housing 1, and a spur gear 64 meshing with the toothed plate a62 is fixed on the rotating shaft 63, a slide groove 65 is opened on the housing 1, a tensioning roller 66 is slidably connected to the slide groove 65, and a toothed plate b67 meshing with the spur gear 64 is fixed on the tensioning roller 66, the length value of the toothed plate a62 is greater than the length value of the toothed plate b67, and the length value of the toothed plate b67 is consistent with the opening length value of the slide groove 65;

[0051] It should be noted that, by moving the gravure plate 53 downward, the toothed plate a62 is driven to move synchronously, and the toothed plate a62 is meshed with the spur gear 64 to drive the gravure plate 53 downward while driving the tensioning roller 66 upward. When the gravure plate 53 moves downward, the tensioning roller 66 is driven to move upward synchronously. The purpose of the coordinated movement is to adjust the tension of the inner lining paper through the pushing action of the tensioning roller 66 during the process of the gravure plate 53 pressing the inner lining paper, thereby ensuring that the inner lining paper can maintain an appropriate tension state during the pressing process, thereby effectively preventing the inner lining paper from wrinkling due to insufficient tension, ensuring that the inner lining paper remains flat during the gravure printing process, avoiding quality problems that may occur during the processing of the inner lining paper, and improving the overall printing effect and product quality of the inner lining paper.

[0052] Embodiment 2:

[0053] Based on the first embodiment, according to Figure 2 , Figure 5 , Figure 7 and Fig. 9As shown, it is worth specifically explaining that the inking unit 7 includes an ink cartridge 71, the ink cartridge 71 is fixed on the housing 1, and a feed pipe 72 connected to the inside of the ink cartridge 71 is fixed on the housing 1. Through the setting of the feed pipe 72, a predetermined amount of photosensitive ink can be added to the ink cartridge 71 in a convenient and timely manner to avoid the situation where the printing effect is poor due to the lack of photosensitive ink in the ink cartridge 71. A plurality of rollers 73 are rotatably connected to the ink cartridge 71, and an inking belt 74 is commonly sleeved on the plurality of rollers 73. A scraper 78 is arranged on a side wall of the ink coating belt 74 with a smooth arc surface. The setting of the belt 74 ensures that the inking belt 74 maintains sufficient smoothness when brushing the photosensitive ink on the lining paper. The vertical cross-section of the inking belt 74 is set in a triangular shape. A servo motor 75 coaxially fixed with one of the rollers 73 and teeth 76 fixed on the roller 73 are fixed on the casing 1, and the inking belt 74 is provided with a toothed groove 77 meshing with the teeth 76. A scraper 78 is fixed on the ink cartridge 71, and the scraper 78 is in contact with the inking belt 74. The conveying roller 3 is located directly above the inking belt 74, and the feed pipe 72 and the ink cartridge 71 are arranged in an inclined distribution.

[0054] It should be noted that the inking belt 74 is driven by the servo motor 75 to operate, and the inking belt 74 is in contact with the lining paper, and the photosensitive ink is applied to the surface of the lining paper, so that the photosensitive ink can be evenly applied to the lining paper. Through the photosensitive color-changing material in the photosensitive ink, as the light and viewing angle change, two colors such as red and green, green and blue, gold and silver can be seen alternating. This optical color contrast feature is obvious, so that the anti-counterfeiting mark on the lining paper presents different colors when observed from multiple angles, which increases the complexity and difficulty of anti-counterfeiting, and further prevents counterfeit cigarettes from circulating in the market and affecting the rights of consumers.

[0055] Example 3: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , this embodiment further explains other embodiments, and it is worth specifically explaining that a plurality of guide grooves 14 are fixed on the casing 1, and the toothed plates a62 and the toothed plates b67 are slidably connected to the inside of the guide grooves 14. The toothed plates a62 and the toothed plates b67 slide in different guide grooves 14 respectively, which not only can guide the toothed plates a62 and the toothed plates b67, but also effectively improve the stability of the toothed plates a62 and the toothed plates b67 when moving. A guide groove 8 is provided on the casing 1, and a sliding roller 9 is slidably connected to the guide groove 8. The sliding roller 9 is located on one side of the conveying roller 3. A mounting frame 10 is fixed on the casing 1, and a screw rod 11 is rotatably connected to the mounting frame 10. A knob 12 is fixed to one end of the screw rod 11, and a threaded sleeve 13 fixed to the sliding roller 9 is threadedly connected to the screw rod 11, and the threaded sleeve 13 is slidably connected to the mounting frame 10;

[0056] It should be noted that by turning the knob 12, the screw rod 11 can be rotated synchronously. The screw rod 11 and the wire sleeve 13 are driven by thread. When the wire sleeve 13 is subjected to force, it moves smoothly along the inside of the mounting frame 10, thereby driving the sliding roller 9 to move accordingly along the inside of the guide groove 8. The tension of the lining paper during the processing can be easily adjusted according to actual processing requirements, which can effectively solve the problem of poor processing effect of the lining paper caused by insufficient tension. In addition, the adjustment method is easy to operate and has strong practicality, making the entire processing process more efficient and precise.

[0057] In this scheme, when it is necessary to press the anti-counterfeiting mark on the lining paper and apply light-sensitive ink, the working principle of the lining paper processing is as follows:

[0058] First, the lining paper is conveyed from the guide roller a2 to the slide roller 9, and the lining paper is placed on the conveying roller 3 to ensure that the lining paper is in contact with the load-bearing plate 54. The anti-counterfeiting mark is printed on the lining paper by the pressing unit 5. The lining paper is conveyed between the ink coating belt 74 and the conveying roller 3, and the photosensitive ink is applied to the lining paper by the ink coating unit 7.

[0059] Secondly, the tension of the liner paper is adjusted according to the actual processing requirements. By turning the knob 12, the screw rod 11 is rotated synchronously. The threaded transmission between the screw rod 11 and the thread sleeve 13 is used to make the slide roller 9 move along the guide groove 8 after receiving the force. The tension of the liner paper can be adjusted according to the actual needs, thereby meeting the processing requirements of the liner paper in different situations.

[0060] Then, the cylinder 52 drives the gravure plate 53 to move downward after receiving force, and the gravure plate 53 applies pressure to the inner lining paper to form an anti-counterfeiting mark on the inner lining paper. When the gravure plate 53 moves downward, the toothed plate a62 is driven to move downward, and the meshing transmission effect between the toothed plate a62 and the spur gear 64 is utilized, and the meshing transmission effect between the spur gear 64 and the toothed plate b67 is coordinated to drive the tensioning roller 66 to move along the slide groove 65 after receiving force, so that when the anti-counterfeiting mark is pressed on the inner lining paper, the tension of the inner lining paper is increased by the tensioning roller 66, and then the flatness of the inner lining paper during printing and processing can be improved;

[0061] Finally, when it is necessary to apply photosensitive ink on the lining paper, the servo motor 75 is driven to make the roller 73 rotate synchronously, and the meshing transmission effect between the teeth 76 and the toothed grooves 77 is used to drive the ink belt 74 to operate, and the scraper 78 is used to scrape the excess ink on the ink belt into the ink cartridge 71, and the ink belt 74 comes into contact with the lining paper, thereby forming a photosensitive ink layer on the lining paper.

[0062] The cylinder 52 and the servo motor 75 can both be purchased from the market and equipped with a separate power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.

[0063] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
