Technical Field
[0001] This invention relates to the field of transfer paper positioning technology, specifically to a positioning photolithography device for positioning transfer paper using photolithography cat's eye technique on cigarette packs. Background Technology
[0002] Transfer paper is a high-end packaging material that achieves special appearance, anti-counterfeiting, or protective functions through functional layer transfer technology. The core logic is to precisely transfer the functional coating on plastic films such as PET and OPP to a paper substrate (such as white cardboard or coated paper) through a composite and peeling process, ultimately forming a composite packaging material that combines the advantages of paper substrate and the characteristics of functional layers. The core of cat-eye positioning transfer paper lies in the platinum cat-eye aluminized layer, which forms a micro-nano structure on the PET film through a UV coating molding process. After vacuum aluminization, it presents a dynamic optical effect similar to a cat's eye. With its technological barriers and aesthetic value, cat-eye positioning transfer paper has become the mainstream choice for high-end cigarette packaging. The photolithography device of the cat-eye transfer paper in cigarette packaging is the core shaping tool for the production of this material. It directly determines the optical effect, positioning accuracy, and application compliance of the transfer paper. It is the core hub connecting anti-counterfeiting security, brand value, production compliance, and cost control.
[0003] When the photolithography device for positioning and transferring the cigarette pack cat's eye paper is misaligned, the correction action is simple and has low precision. It is difficult to make targeted adjustments according to the degree of misalignment. Moreover, it is easy to overcorrect, leading to new positional deviations, or to not correct completely.

[0014] This invention provides a positioning photolithography device for positioning transfer paper of a cigarette pack using photolithography for cat's eye printing. It has the following beneficial effects: (i) The positioning photolithography device for the cigarette pack photolithography cat's eye positioning transfer paper, through the loading mechanism, pushes the disassembly block to slide along the hollow rod by the upward push rod, which can flexibly adjust the spacing to adapt to different paper rolls. With the cooperation of the deformation sleeve being squeezed and expanded by the inclined block, the paper roll is internally supported and fixed. The shaft end retaining ring can also limit the axial displacement of the paper roll to avoid the paper roll from loosening. The driving component of the feeding component drives the feeding roller to transport the transfer paper. The connecting pad prevents the feeding roller from shaking, ensuring uniform and stable conveying, and effectively avoiding the deviation of subsequent processes caused by unstable loading and conveying fluctuations.
[0015] (II) The positioning photolithography device for the cigarette pack cat-eye positioning transfer paper first performs an initial offset scan on the transfer paper through the initial detection component, and the offset detection component further assists in the confirmation. The dual detection can promptly capture initial and minor offset problems. The correction mechanism pushes the top plate to quickly correct obvious offsets through the correction push rod of the fast correction component. The guide rod ensures stable operation. The tensioning component adjusts the tension to avoid secondary offsets. The fine adjustment component uses fine adjustment push rods, inclined blocks, etc. to correct minor deviations, forming a closed-loop control to ensure that the transfer paper is always transported along the preset trajectory.
[0016] (III) The positioning photolithography device for the cigarette pack photolithography cat's eye positioning transfer paper, through the coordinated operation of the winding, conveying, detection and correction links, enables the transfer paper to enter the photolithography machine in a precise position and stable state, effectively avoiding pattern misalignment and offset caused by the offset of the transfer paper during photolithography, significantly reducing the scrap rate, eliminating the need for frequent manual adjustments of each mechanism, reducing processing interruption time, improving overall production efficiency, meeting the strict requirements of photolithography positioning accuracy for cigarette pack transfer paper, and ensuring product processing consistency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1, please refer to Figures 1 to 2This invention provides a positioning photolithography device for a cigarette pack cat's eye positioning transfer paper, including a photolithography machine 1. A winding mechanism 2 is mounted on one side of the photolithography machine 1. A feed detection mechanism 3 is mounted on the surface of the photolithography machine 1. A correction mechanism 4 is provided inside the feed detection mechanism 3. The feed detection mechanism 3 includes a feed component 31, the surface of which is in contact with the surface of the photolithography machine 1. An offset detection component 32 is provided on one side of the feed component 31. An initial detection component 33 is mounted on the surface of the offset detection component 32. The correction mechanism 4 includes... The rapid correction component 41 has a surface that contacts the surface of the initial detection component 33. A tensioning component 42 is mounted on the surface of the rapid correction component 41, and a fine-tuning component 43 is provided on the surface of the tensioning component 42. The rapid correction component 41 includes a guide rod 412 and a correction push rod 413. A top plate 414 is fixedly connected to the end of the guide rod 412. The fine-tuning component 43 includes a recess 431, a connecting block 437 is fixedly connected to the outer surface of the recess 431, and a fine-tuning push rod is fixedly connected to the outer surface of the connecting block 437. 436, the inner wall of the concave block 431 is slidably connected to the inclined plate 432, and the surface of the inclined plate 432 is fixedly connected to the sliding member 433. The feed detection mechanism 3 integrates the correction mechanism 4, which can correct the position deviation of the transfer paper in real time. When the transfer paper is conveyed to the area by the feed component 31, the initial detection component 33 first performs a preliminary scan on the edge position and conveying trajectory of the transfer paper to identify whether there is a significant deviation. At the same time, the deviation detection component 32 assists in providing an initial deviation signal for subsequent correction. The surface of the fast correction component 41 in the correction mechanism 4 is in contact with the surface of the initial detection component 33. When the initial detection component 33 detects a significant deviation, the fast correction component 41 is activated, and the correction push rod 413 inside it generates a thrust, which drives the guide rod 412 to move along the preset direction. The top plate 414 fixed at the end of the guide rod 412 directly contacts the edge of the transfer paper. The thrust quickly pulls the transfer paper back to the approximate preset trajectory, correcting the significant position deviation. The guide rod 412 also plays a guiding role to prevent the top plate 414 from deviating when it moves, ensuring the stability of the fast correction action.

The structural stability of the 13 is ensured by the shaft end retaining ring 222 fixed at the end of the deformable sleeve 221, which restricts the axial displacement of the paper roll and prevents it from sliding axially. When the inner shaft 224, which is slidably connected to the inner wall of the deformable sleeve 221, is pushed, the inner wall of the groove 225 on the surface of the inner shaft 224 slides and engages with the inner wall of the inclined block 223 fixed to the inner wall of the deformable sleeve 221.

[0023] The working principle of the positioning photolithography device for the cigarette pack photolithography cat's eye positioning transfer paper is described in detail below: In use, the transfer paper roll is installed and fixed by the loading mechanism 2. The base plate 211 of the support component 21 is kept stable with the support frame 213 by means of the reinforcing member 212. The upward push rod 215 pushes the disassembly block 216 to slide along the hollow rod 214 to adjust the spacing to fit the paper roll. After the deformation sleeve 221 of the inner support component 22 is fitted with the paper roll, the inner shaft 224 slides to make the inclined block 223 squeeze the deformation sleeve 221 to expand and achieve internal support and fixation. The mounting shaft 226 further positions to ensure the stability of the paper roll. Then the feeding component 31 of the feeding detection mechanism 3 is started. The driving component 312 in the protective shell 311 drives the feeding roller 313 to rotate. Under the stabilizing effect of the connecting pad 314, the transfer paper is conveyed towards the photolithography machine 1. During the transfer paper conveying process, the deflection roller 333 of the initial detection component 33 changes the conveying angle, and the offset detector 334 performs initial detection. In the second offset detection, the drive motor 322 of the offset detection component 32 drives the positioning roller 324 to rotate, and the limiting ring 325 restricts the lateral displacement. The secondary detector 326 completes the second accurate detection and transmits the offset signal. Then, the correction mechanism 4 responds to the signal, and the correction push rod 413 of the fast correction component 41 pushes the top plate 414. Under the stabilization of the guide rod 412, the obvious offset is quickly corrected. The tension push rod 422 of the tensioning component 42 pushes the connecting rod 423 to slide along the directional rod 424, which drives the clamping roller 426 to adjust the tightness of the transfer paper to avoid loosening. The fine adjustment push rod 436 of the fine adjustment component 43 pushes the concave block 431 to slide along the guide rail 435. The inclined plate 432 achieves precise fine adjustment through a small thrust. Finally, the transfer paper with accurate positioning and stable state enters the photolithography machine 1, completes the processing of the cat's eye pattern on the cigarette pack, and is output along the subsequent path.
