Description

Technical Field

[0001] This utility model relates to the field of adhesive application devices, and in particular to an adhesive application device for preparing large picture books that can be easily pasted on walls. Background Technology

[0002] Gravure coating machines are commonly used in printing, packaging, and coating industries. Their main function is to evenly and precisely apply coating liquid to the surface of materials. During operation, the machine rotates, carrying the coating liquid with it. A doctor blade scrapes away excess coating liquid from the anilox surface, leaving the liquid in the pores. A back pressure roller presses the substrate against the anilox roller surface. The anilox roller, carrying the substrate, moves in the same direction as the back pressure roller, transferring the coating liquid from the pores to the substrate at a predetermined ratio. This process completes the coating. Because the anilox roller, back pressure roller, and substrate move in the same direction, this process is called co-directional coating. The use of a coating structure in the coating device is crucial.

[0003] Existing glue coating devices have certain drawbacks. First, during operation, the coating roller has a large contact area with the coating box, and the glue or release agent is constantly stirred in the glue box as the coating roller rotates. Over time, this causes moisture loss in the glue and deactivation of the release agent, resulting in reduced product processing efficiency and increased waste of glue and release agent. To address this, we propose a glue coating device that is convenient for preparing large picture books that can be pasted on walls. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a gluing device for preparing large picture books that can be pasted on walls. By setting up a second linkage roller, which is separate from the roller body and coaxially connected by a connecting shaft, this two-section series combination design can effectively handle the required coating area. In addition, the small size of the glue box reduces the amount of glue or release agent used during operation. The small spread area of ​​glue or release agent in the glue box makes the adhesive force of the glue or release agent more stable during operation. This makes the gluing device more practical for the preparation and processing of large picture books that can be pasted on walls, improving product quality and reducing the waste of glue and release agent.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A gluing device for preparing large picture books that can be easily pasted on a wall includes a gluing device body, a roller body rotatably connected to the inner side of the gluing device body, a connecting shaft installed at the inner end of the roller body, and a second linkage roller sleeved at the outer end of the connecting shaft, the second linkage roller having a gluing part.

[0007] By installing the second linkage roller, product quality was improved and waste of glue or release agent was reduced.

[0008] Furthermore, a glue box is movably connected below the second linkage roller, and the length of the glue box matches that of the second linkage roller.

[0009] The practical effect of the glue coating device is further improved by installing a glue box that matches the second linkage roller.

[0010] Furthermore, a scraper is movably connected to one side of the upper part of the second linkage roller.

[0011] By installing a scraper, the scraper length is shortened, the installation process is changed, and the glue application work becomes more convenient.

[0012] Furthermore, a support frame is installed at the bottom of the glue box, and connecting frames are installed at both ends of the support frame, the connecting frames being L-shaped.

[0013] By installing a support frame, the stability of the device structure during use is improved.

[0014] Furthermore, an assembly bracket is mounted on the outer end of the scraper.

[0015] By installing an assembly frame, the scraper can be used stably.

[0016] Furthermore, connecting discs are installed at both ends of the connecting shaft, and the connecting discs are connected to the body of the adhesive applicator.

[0017] By installing the connecting plate, the connecting shaft is stably connected to the glue application device body.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. By setting up a second linkage roller, which is separate from the main roller and coaxially connected by a connecting shaft, this two-section series combination design can effectively handle the required coating area. In addition, the small size of the glue box reduces the amount of glue or release agent used during operation. The small spread area of ​​glue or release agent in the glue box makes the adhesive force of the glue or release force of the release agent more stable. This makes the glue coating device more practical for the preparation and processing of large picture books pasted on the wall, improving product quality and reducing the waste of glue and release agent.

[0020] 2. By setting a glue box that matches the second linkage roller, the glue box differs from the traditional design with a larger length. The size is reduced, which effectively cooperates with the second linkage roller to apply glue or release agent. This effectively avoids the problem that the glue or release agent is constantly stirred in the glue box as the roller rotates during use, which would cause the glue to lose moisture and the release agent to become ineffective over time. This further improves the effect of the glue application device.

[0021] 3. By setting a scraper, which is designed to match the length of the second linkage roller, and by changing the installation process, it can be used to facilitate glue application with the second linkage roller. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0029] Reference Figure 1-4 As shown, this is a preferred embodiment of the present invention for preparing a large picture book that can be pasted on a wall. It includes a glue applicator body 1, a roller body 2 rotatably connected to the inner side of the glue applicator body 1, a connecting shaft 3 installed at the inner end of the roller body 2, and a linkage roller 4 sleeved on the outer end of the connecting shaft 3. The linkage roller 4 is provided with a glue applicator part 5.

[0030] By installing the linkage roller 2 4 separately from the roller body 2 and coaxially connected by the connecting shaft 3, this two-section series combination design can effectively handle the required coating parts. The small size of the glue box 6 reduces the amount of glue or release agent used during operation. The small spread area of ​​glue or release agent in the glue box 6 makes the adhesive force of the glue or the release force of the release agent more stable during operation. This makes the glue coating device more practical for the preparation and processing of large picture books that are pasted on the wall.

[0031] Reference Figure 2-3 As shown, a glue box 6 is movably connected below the second linkage roller 4, and the length of the glue box 6 matches that of the second linkage roller 4.

[0032] By installing the glue box 6, the traditional design with a larger length is distinguished. The size is reduced, which can effectively cooperate with the linkage roller 2 4 to apply glue or release agent. This effectively avoids the problem that the glue liquid inside the glue box 6 is constantly stirred with the rotation of the roller body 2 during the use of glue or release agent, which will cause the glue to lose moisture and the release agent to become ineffective over time.

[0033] Reference Figure 1 and Figure 4 As shown, a scraper 7 is further movably connected to one side of the upper part of the linkage roller 4.

[0034] By installing the scraper 7 and adopting a design that matches the length of the linkage roller 4, and by changing the installation process, it is possible to easily apply adhesive in conjunction with the linkage roller 4.

[0035] Reference Figure 2 As shown, a support frame 8 is further installed at the bottom of the plastic box 6, and connecting frames 9 are installed at both ends of the support frame 8. The connecting frames 9 have an L-shaped structure.

[0036] Reference Figure 2 As shown, the outer end of the scraper 7 is further equipped with an assembly bracket 10.

[0037] Reference Figure 2-3 As shown, furthermore, connecting discs 11 are installed at both ends of the connecting shaft 3, and the connecting discs 11 are connected to the glue applicator body 1.

[0038] By installing the support frame 8 and connecting frame 9, a support structure can be formed at the outer end of the glue box 6, making the glue box 6 more stable during use. The assembly frame 10 can form a support connection structure at the outer end of the scraper 7, making the scraper 7 stable during use. The connecting plate 11 can form a connection structure at both ends of the connecting shaft 3, making the connection between the connecting shaft 3 and the glue application device body 1 stable.

[0039] Specific implementation process: When producing large-format picture book products that can be pasted on walls, this device only requires applying a 35-65mm strip of glue or release agent. The roller body 2 rotates, and the second linkage roller 4, which is separate from the roller body 2 but coaxially connected by a connecting shaft 3, rotates simultaneously. This two-section series combination design effectively handles the required coating area. Furthermore, the small size of the glue box 6 reduces the amount of glue or release agent used during operation. The small spread of glue or release agent within the glue box 6 makes the adhesive strength of the glue or the release force of the release agent more stable. The distance between the second linkage roller 4 and the contact point with the substrate is shortened. The lower glue box 6 differs from the traditional design with a larger length; its size is smaller, and the slurry tank volume is smaller, storing less coating liquid and requiring less replacement. The small amount of coating liquid required significantly reduces development costs. It effectively works in conjunction with the second linkage roller 4 to apply adhesive or release agent, effectively avoiding the problem of the adhesive liquid inside the glue box 6 being constantly stirred as the roller body 2 rotates, which would cause moisture loss of the adhesive and failure of the release agent over time. During the coating process, the scraper 7 is designed to match the length of the second linkage roller 4, and the installation process has been modified to facilitate convenient coating in conjunction with the second linkage roller 4. During coating, the section of coating liquid from the concave roller leaving the liquid surface to the contact point or surface of the substrate is an arc of less than 90 degrees. Therefore, the exposed area of ​​the coating liquid is small and the time is short, which is very suitable for highly volatile solvent-based coating liquids. Moreover, it will not cause clogging of the mesh cavities, thus increasing the coating effect of the device.
