Description

Technical Field

[0001] The utility model relates to the technical field of cigarette printing, in particular to a laminating and gluing device capable of adjusting the glue position. Background Art

[0002] Lamination is a printing process in which a transparent plastic film is applied to the surface of printed materials through heat and pressure to protect and enhance the gloss. Lamination is widely used for surface binding and protection on book covers, albums, commemorative books, postcards, product brochures, calendars, and maps. Lamination production requires a certain amount of glue to be injected into the laminating machine's glue tank to ensure effective adhesion between the film and the paper. During mass lamination production, a significantly higher amount of glue than the tank capacity is typically required. A tank overflow circulation system ensures that the glue level in the tank remains at a constant level, ensuring contact with the applicator roller, ensuring consistent and stable lamination. However, during low-volume production or proofing, when only minimal glue is consumed, a larger amount of glue must be added to ensure effective contact with the applicator roller. This poses challenges in both storage and use, as well as recycling and disposal.

[0003] Patent document CN203739417U discloses a liquid level adjustment mechanism for an ink cartridge in a unit-type gravure printing press. This mechanism addresses technical issues in existing unit-type gravure printing presses, such as the lowering of the ink level, which can result in insufficient ink supply to the printing plate roller and thus affect printing quality. The liquid level adjustment mechanism comprises a plurality of airbags. The ink cartridge has an ink chamber for holding ink. The airbags are fixed to the bottom of the ink chamber. The airbags are arranged in two rows along the length of the ink cartridge, one on each side of the ink chamber. An inflator is fixed to the frame, and an inflation hose is provided between the inflator and the airbags. The inflation hose comprises a main pipe and a plurality of branch pipes corresponding to the airbags. The main pipe is connected to the inflation port of the inflator, one end of the branch pipe is connected to the main pipe, and the other end of the branch pipe is connected to the corresponding airbag.

[0004] This prior art changes the volume of the ink cartridge's ink-holding portion by inflating and deflating the airbag. This reduced volume allows even a small amount of ink to be maintained at a higher level. However, the airbag is fixed to the cartridge's inner bottom, so deformation occurs upward. Furthermore, an ink roller for absorbing ink is located above the cartridge, and upward deformation of the airbag could potentially contact the roller, affecting not only its ability to absorb ink but also its position, potentially shifting and impacting printing results. The laminating process is similar, with a glue roller located above the glue tank to absorb the glue. This drawback prevents its effective application within the glue tank. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a laminating and gluing device which can adjust the glue position to assist the laminating glue to contact the gluing roller when the laminating glue is insufficient and will not affect the gluing roller.

[0006] The technical solution to the problem solved by the present invention is to provide a film-coating and gluing device with adjustable glue position, comprising a glue groove and a glue coating roller arranged above the glue groove; further comprising an adjusting structure for adjusting the glue liquid level in the glue groove; the adjusting structure comprises an internally hollow support tube and a deformable capsule; the support tube is suspended in the glue groove, the support tube comprises a bottom close to the bottom of the glue groove, the bottom is provided with an opening; the capsule is closed in the opening; the adjusting structure further comprises an inflatable member for inflating the inner cavity of the support tube to deform the capsule.

[0007] As a preferred embodiment of the present invention, the length direction of the support tube is parallel to the bottom of the glue groove, and the bottom of the support tube is provided with a plurality of openings along the length direction.

[0008] As a preferred embodiment of the present invention, the length direction of the support tube is perpendicular to the bottom of the glue groove.

[0009] As a preferred embodiment of the present invention, the bladder casing includes an outer ring connecting portion connected to the inner wall of the bottom, and a central deformation portion covering the opening.

[0010] As a preferred embodiment of the present invention, a gravity pressure plate is provided in the support tube, and the outer ring connecting portion is provided between the gravity pressure plate and the bottom; and an air hole is provided in the portion of the gravity pressure plate located above the opening.

[0011] As a preferred embodiment of the present invention, the inner wall of the bottom is provided with a card slot, and the gravity pressure plate is provided with a card block engaged with the card slot; the outer ring connecting portion includes an anti-slip portion located between the card slot and the card block.

[0012] As a preferred embodiment of the present invention, the gravity pressure plate is magnetically connected to the bottom.

[0013] As a preferred embodiment of the present invention, the adjustment structure also includes a fixing member for suspending the support tube in the glue groove, and the fixing member includes a overlapping portion for overlapping the top of the glue groove side plate, and a connecting portion connected to the support tube.

[0014] As a preferred embodiment of the present invention, the connecting portion is hollow inside and communicates with the inner cavity of the support tube. The connecting portion is provided with an inflation port and an air plug for closing the inflation port.

[0015] As a preference of the present invention, the angle between the side wall of the opening and the bottom is a rounded angle.

[0016] Beneficial effects of the utility model:

[0017] 1. In this application, the bladder is placed at the bottom of the support tube and then placed in the glue tank. When the support tube is inflated, the bladder can only expand and deform downward. On the one hand, the expanded bladder occupies the inner cavity of the glue tank, reducing the volume of the portion of the glue tank that can accommodate the glue liquid, allowing a small amount of glue to be maintained at a high liquid level for effective contact with the glue roller. In addition, due to the support tube's fixed effect on the bladder, the bladder will not float to the liquid surface after inflation, ensuring that the airbag structure is always below the glue liquid level. On the other hand, because the bladder expands and deforms downward, no matter how much air is inflated, the bladder will not deform to the point of contacting the glue roller and causing adverse effects, thus ensuring the glue coating effect.

[0018] 2. In some embodiments, the support tube can be installed vertically on the inner wall of the glue groove, and the glue groove and the glue coating roller do not need to be moved during the installation and disassembly process. It is suitable for retrofitting and modifying the existing laminating and gluing device to avoid the position of the glue groove or the glue coating roller being offset during the modification process, thereby affecting the laminating and gluing effect.

[0019] 3. In some embodiments, the capsule cover is fixed in the support tube by a gravity pressure plate. After the gravity pressure plate is removed, the capsule cover can be disassembled and replaced, which is convenient for cleaning the adjustment structure and replacing the capsule cover after it is damaged.

[0025] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] Example 1

[0027] A film-coating and gluing device with adjustable glue position, such as Figure 1 As shown, it includes a glue tank 11 and a glue coating roller 12 arranged above the glue tank 11. When in use, the glue coating roller 12 rotates until it contacts the glue in the glue tank 11, and the mesh on it can absorb the glue. Then the glue coating roller 12 continues to rotate, and the glue in the mesh can be transferred to the printed matter unfolded between the glue coating roller 12 and the support roller to complete the gluing.

[0028] In the film-coating and gluing device, the positions of the glue tank 11, the glue roller 12, and the support roller are usually fixed and should not be easily adjusted. When the glue in the glue tank 11 decreases and the glue level drops, the glue roller 12 will be unable to absorb the glue. However, during the small-scale production or proofing process of the film-coating and gluing device, only a very small amount of glue is usually consumed. However, in order to maintain the glue level in the glue tank 11, a large amount of glue must be prepared. This is not only inconvenient for storing and using the glue, but also not conducive to the recycling and disposal of the glue after use. Therefore, the present application also includes an adjustment structure for adjusting the liquid level of the glue in the glue tank 11.

[0029] The adjustment structure includes a hollow support tube 21, a deformable bag cover 22, and an inflatable member. The support tube 21 is arranged in the glue groove 11. In this embodiment, Figure 1 As shown, the support tube 21 is arranged parallel to the glue groove 11, that is, the length direction of the support tube 21 is parallel to the bottom of the glue groove 11. In this application, the support tube 21 should be suspended in the glue groove 11 and there should be a gap between it and the bottom of the glue groove 11 to provide space for the subsequent deformation of the capsule 22. Therefore, the adjustment structure also includes a fixing member 24 for suspending the support tube 21 in the glue groove 11, such as Figure 1 As shown, fixing parts 24 are respectively provided at both ends of the support tube 21. The fixing parts 24 include a horizontal overlapping portion 241 for overlapping the top of the side panel of the glue groove 11, and a vertical connecting portion 242 connected to the support tube 21. Furthermore, a stopper portion for abutting against the outer wall of the glue groove 11 can be connected to the overlapping portion 241, so that the fixing part 24 forms an inverted U-shaped structure stuck on the side panel of the glue groove 11.

[0030] The support tube 21 includes a bottom portion 211 near the bottom of the adhesive groove 11. The support tube 21 can be a round tube or a square tube. In this embodiment, in order to facilitate the subsequent installation of the gravity pressure plate 23, the support tube 21 is a square tube, formed by sealingly connecting four non-deformable hard plates. At the same time, openings are formed at both ends of the support tube 21. When the support tube 21 is placed parallel to the adhesive groove 11, the plate at the bottom becomes the bottom portion 211. Based on the structure of the above-mentioned fixing member 24, the two ends of the support tube 21 are respectively connected to the connecting portion 242. When the connecting portion 242 is a solid structure, the two openings can be closed by the connecting portion 242. Then, an inflation port is opened at other positions of the support tube 21 and connected to the inflation member through an air pipe to achieve inflation into the support tube 21. In some embodiments, the connecting portion 242 can also be configured as a square tube that is hollow inside and connected to the inner cavity of the support tube 21. Therefore, the end opening of the support tube 21 is connected to the lower end opening of the connecting portion 242, and the upper end opening of the connecting portion 242 forms an inflation port. Generally, an air plug for closing the inflation port is also provided at this inflation port.

[0031] The bottom 211 of the support tube 21 is provided with a plurality of openings along the length direction, and the openings are then sealed with the bladder 22. In some embodiments, as Figure 2 As shown, the angle between the side wall of the opening and the solid portion of the bottom 211 is rounded to prevent the capsule 22 from being damaged by a sharp end angle.

[0032] The capsule 22 and the support tube 21 can be fixedly connected: for example, the outer ring portion of the capsule 22, referred to as the outer ring connection portion 221 in this embodiment, can be directly fixed to the inner wall of the opening by gluing, and the central portion of the capsule 22, referred to as the central deformation portion 222 in this embodiment, naturally covers the opening; or, in order to increase the connection area and thus improve the fixing effect, the outer ring connection portion 221 can be further fixed to the inner wall of the bottom 211. The capsule 22 and the support tube 21 can also be movably connected as in this embodiment: as Figure 2 As shown, a gravity pressure plate 23 is provided in the support tube 21. The area of the gravity pressure plate 23 is consistent with the area of the bottom 211. The side surfaces of the gravity pressure plate 23 are in contact with the inner wall of the support tube 21. The outer ring connecting portion 221 of the bladder 22 is clamped between the gravity pressure plate 23 and the bottom 211. At the same time, the part of the gravity pressure plate 23 located above the opening is provided with an air hole 231 for gas to enter the bladder 22 to cause the central deformation portion 222 to expand.

[0033] The gravity pressure plate 23 is preferably made of a material with a high density, such as lead, to increase the pressure on the outer ring connection portion 221 to prevent the bag 22 from falling off. In some embodiments, the gravity pressure plate 23 can also be magnetically connected to the bottom 211 to further clamp the outer ring connection portion 221. In some embodiments, such as Figure 2As shown, the inner wall of the bottom 211 is provided with a slot, and the gravity pressure plate 23 is provided with a block 232 that engages with the slot. The outer ring connecting portion 221 includes an anti-slip portion located between the slot and the block 232, which prevents the capsule 22 from falling off by forming a concave-convex structure. When the capsule 22 needs to be removed or replaced, the gravity pressure plate 23 is lifted upward to release the pressure on the outer ring connecting portion 221 of the capsule 22.

[0034] In some embodiments, in order to facilitate lifting the gravity pressure plate 23 upward, as shown in FIG. Figure 1 As shown, lifting plates are installed in the connecting portions 242 at each end of the support tube 21. As mentioned above, the connecting portion 242 is a square tube. The side panels near the overlapped portion 241, referred to in this embodiment as the outer panels, are provided with notches. The lifting plates are attached to the inner walls of the outer panels. The lower ends of the lifting plates are connected to the gravity pressure plate 23, while the upper ends protrude from the outer panels and are provided with stoppers that engage the notches. Controlling the stoppers can drive the gravity pressure plate 23 upward.

[0035] Based on the above structure, when the inflatable member is inflated, gas enters the inner cavity of the support tube 21 through the inflation port. Continued inflation, when the gas volume exceeds the volume of the connecting portion 242 and the inner cavity of the support tube 21, causes the central deformable portion 222 of the bladder casing 22 to expand outward. The expansion of the bladder casing 22, located in the adhesive liquid, causes the adhesive liquid level to rise. By adjusting the amount of gas inflated, the amount of expansion of the bladder casing 22, and thus the height of the adhesive liquid rise, can be adjusted until the adhesive liquid effectively contacts the upper adhesive coating roller 12.

[0036] Example 2

[0037] This embodiment is basically the same as the first embodiment, except that:

[0038] like Figure 3 As shown, in this embodiment, the support tube 21 is vertically arranged in the glue groove 11, that is, the length direction of the support tube 21 is perpendicular to the bottom of the glue groove 11. The support tube 21 can be a round tube or a square tube. The lower end of the support tube 21 becomes its bottom 211, and is provided with an opening and a bag 22, and the upper end forms an inflation port. Since the area of the bottom 211 of the support tube 21 is limited at this time, only one or two bags 22 can be set. Therefore, multiple support tubes 21 can be set, respectively arranged on the four side panels of the glue groove 11. Compared with the design mode of the horizontal support tube 21, the design mode of the vertical support tube 21 does not require the support tube 21 to pass through the space between the glue coating roller 12 and the glue groove 11 when installing and disassembling, and is not easy to cause unnecessary influence on the glue coating roller 12 and the glue groove 11 during the installation and disassembly process.

[0039] Based on the vertically arranged support tube 21, the structure of the fixing member 24 changes. In this embodiment, as shown in FIG. Figure 4As shown, the fixing member 24 includes a horizontal overlapping portion 241 for overlapping the top of the side panel of the glue groove 11. The end surface of the overlapping portion 241 close to the glue groove 11 becomes a connecting portion 242, which is fixedly connected to the outer side of the support tube 21. At the same time, the lifting structure for lifting the gravity pressure plate 23 is changed. The lifting structure is a lifting tube that is in contact with the inner wall of the support tube 21. The lifting tube is used to allow gas to flow to the bladder 22.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
