Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cardboard coating technology, and in particular relates to a cardboard coating device for advertising production. Background Technology
[0002] Advertising production refers to the commercial activities of creating advertising works that can be published, set up, posted, and distributed according to advertising design requirements. Advertising boards are a means of publicity that uses a certain form of media to publicly and widely convey information to the public for a specific need. In the process of making advertising boards, it is often necessary to paste the graphic paper onto the advertising cardboard, and before pasting the graphic paper, a layer of glue is often applied to the advertising cardboard.
[0003] For example, patent application number CN202223496535.1 discloses an advertising cardboard gluing device for advertising production, belonging to the technical field of gluing devices. It includes a base, with columns fixedly connected to the four corners of the base's top surface. A top plate is fixedly connected to the top of the four columns, and a mounting plate is fixedly connected to the top surface of the base. Under the action of the driving mechanism, the gluing nozzles and smoothing rollers can achieve uniform horizontal movement, facilitating the even application of glue to the sides of the advertising cardboard. Furthermore, the servo motor drive makes it easier to control, increasing the device's practicality. Under the action of the adjustment mechanism, the positions of the three gluing nozzles can be adjusted, facilitating gluing of advertising cardboard of different sizes. Under the action of the spring telescopic rod, the smoothing rollers always adhere to the top surface of the cardboard, facilitating the smoothing of the glue strip. The cooperation of the locking groove and locking seat ensures that the mounting frame can rotate, facilitating re-applying of glue.
[0004] Existing technology enables the glue-applying nozzle and smoothing roller to move horizontally at a uniform speed under the action of a drive mechanism, which facilitates the even application of glue to the sides of the advertising cardboard. However, there are still some shortcomings in its overall use: First, existing technology involves spraying glue onto the surface of the cardboard and then applying the glue with a coating roller. This method is prone to excessive glue penetration or splashing, resulting in low utilization. Furthermore, if the initial spraying is uneven, the coating roller is difficult to completely correct, leading to localized delamination or insufficient strength of the cardboard. Secondly, if the glue roller does not remove the glue after applying the glue and immediately applies glue to the next piece of cardboard, the dried glue or dirt remaining on the roller will cause the newly applied glue line to be intermittent or dripping, resulting in poor local bonding of the cardboard and a significant reduction in strength. The air bubbles in the residual glue will be transferred to the new cardboard, resulting in white spots, bubbles or hollows after lamination, which seriously affects the appearance and bonding strength of the product. Finally, the traditional method of fixing cardboard can easily create dead corners, resulting in some areas not being properly glued during the gluing process, thus reducing the quality of the glue application. Utility Model Content
[0005] This invention addresses the technical problems of existing technologies where spraying followed by roller coating can easily lead to glue splashing and uneven penetration, resulting in localized delamination of cardboard, unstable bonding strength, and the inability of the coating roller to be cleaned in time, causing residual glue residue and air bubbles to directly contaminate the next coating, resulting in quality defects such as discontinuous glue lines, air bubbles, and hollow areas. It also addresses the inflexible cardboard fixing methods that easily create blind spots in the coating process, leading to incomplete coating in some areas and affecting the overall bonding quality. The invention provides a cardboard coating device for advertising production.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cardboard gluing device for advertising production, comprising a base, a placement groove on the upper surface of the base, a U-shaped mounting frame above the placement groove, a gluing roller rotatably mounted between the two sides of the mounting frame, a vertical plate slidably mounted on one side of the top of the mounting frame, a limit block fixedly mounted at the top of the vertical plate, a brush abutting against the gluing roller at the bottom of the vertical plate, a support block fixedly mounted at the bottom of the mounting frame, a roller assembly slidably mounted at the bottom of the support block, and a connecting rod fixedly mounted between the outer side of the vertical plate and the frame of the roller assembly.
[0007] Optionally, a spring is fixedly installed inside the support block, and the frame of the roller assembly is fixed to the top of the spring.
[0008] Optionally, a counterweight is fixedly installed at the bottom of the vertical plate, and the brush is fixedly installed at the bottom of the counterweight.
[0009] Optionally, electric slide rails are fixedly installed on both sides of the base, a bracket is fixedly installed on the top of the slider of the electric slide rail, a top plate is fixedly installed on the top of the bracket, and an electric push cylinder is fixedly installed on the top of the top plate. The output end of the electric push cylinder is fixed to the upper surface of the mounting frame.
[0010] Optionally, a glue box is fixedly installed on the top of the top plate, a glue inlet pipe is provided on the top of the glue box, and a conduit is connected to the bottom of the glue box.
[0011] Optionally, the upper surface of the base is fixedly equipped with sliding grooves on both sides of the placement groove, and the roller assembly moves inside the sliding grooves.
[0012] Optionally, one end of the base has a groove, and a removable collection box is installed inside the groove.
[0013] Optionally, side plates are fixedly installed on the upper surface of the base on both sides of the collection box, and a scraper is fixedly installed between the two side plates.
[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This utility model, through the setting of a coating roller, a brush, a support block, a spring and a roller assembly, can evenly apply glue to the coating roller before the cardboard is coated, so that the cardboard can be coated evenly, effectively improving the coating effect. At the same time, it is different from the existing technology, which helps to improve the uniformity of glue application and achieve extremely high glue application accuracy and stability. (2) This utility model can quickly limit the cardboard by setting up a placement groove, a collection box and a scraper, and expose the upper surface of the cardboard, so that the entire surface of the cardboard can be coated with glue. At the same time, it can remove the glue residue on the coating roller before the next coating, avoid the residue of glue and air bubbles from contaminating the next coating, improve the coating quality, and collect the dripping glue for recycling, reducing the cost of use.

Detailed Implementation
[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] refer to Figure 1 and Figure 2 An adhesive applicator for advertising cardboard includes a base 10. A placement groove 11 is formed on the upper surface of the base 10 for placing cardboard. The placement groove 11 is designed to be slightly larger than the width of the cardboard, with a standard deviation of 1-2 mm. The placement groove 11 secures the cardboard through precise dimensional fitting and multi-directional physical restraint via side walls, baffles, and the bottom of the groove. The bottom of the placement groove 11 is also roughened to increase friction, effectively preventing the cardboard from shaking during the adhesive application process. Unlike traditional spraying followed by scraping and spreading, this application uses an adhesive roller 17 for rolling adhesive application. The downward pressure applied by the roller, compared to the inclined pressure applied by a scraper, also applies downward pressure to the cardboard during adhesive application, further preventing cardboard shaking. Therefore, this application avoids using a clamping and fixing mechanism to limit its position through the above-mentioned structure, reducing the generation of dead corners in the coating. In addition, in this application, the height of the cardboard is more than one-third higher than the depth of the placement groove 11, so that the placement groove 11 can fully expose the upper surface of the cardboard, thereby enabling the entire surface of the cardboard to be coated with glue, improving the coating effect. One end of the base 10 has a groove, and a detachable collection box 33 is fixedly installed inside the groove to collect excess glue for recycling, reducing the cost of use.
[0019] Further reference Figure 1 , Figure 2 , Figure 5 and Figure 8 Electric slide rails 12 are fixedly installed on the front and rear sides of the base 10. The electric slide rails 12 are existing technology, and the slider is driven by an electric motor to move on the rails. They will not be described in detail in this solution. A bracket 13 is fixedly installed on the upper surface of the slider of the electric slide rail 12. A top plate 14 is fixedly installed on the top of the bracket 13. An electric push cylinder 15 is fixedly installed on the top of the top plate 14. The conveying end of the electric push cylinder 15 slides through the top plate 14. A U-shaped mounting bracket 16 is fixedly installed on the end of the electric push cylinder 15. A glue-applying roller 17 is rotatably installed between the opposite surfaces of the mounting bracket 16. Furthermore, a motor 18 for driving the glue application roller 17 is fixedly installed on one side of the mounting frame 16, and a glue tank 19 is fixedly installed on the upper surface of the top plate 14 on one side of the electric push cylinder 15. The glue tank 19 has a built-in delivery pump, which is existing technology and will not be described in detail in this solution. A glue inlet pipe 20 is provided on the top of the glue tank 19 for replenishing glue into the glue tank 19. Multiple conduits 21 connected to the delivery pump are provided at the bottom of the glue tank 19. A fixing block 22 for limiting the conduits 21 is fixedly installed on the lower surface of the mounting frame 16, and a glue spraying head 23 is fixedly installed at the bottom end of the conduits 21. In use, the initial position of the coating roller 17 is above the collection box 33. The glue in the glue box 19 is sprayed onto the surface of the coating roller 17 through the glue spray head 23. At this time, the motor 18 drives the coating roller 17 to rotate, so that the outer surface of the coating roller 17 is covered with glue. Excess glue drips into the collection box 33 for collection. Then, the electric push cylinder 15 pushes the mounting frame 16 and the coating roller 17 to move downward, so that the coating roller 17 abuts against the upper surface of the cardboard. Then, the electric slide rail 12 drives the coating roller 17 to move laterally, so that the entire cardboard can be covered with glue. Unlike the existing technology that first sprays glue onto the surface of the cardboard and then uses the coating roller 17 to apply glue, this setting can help improve the uniformity of glue application, achieve extremely high glue application accuracy and stability, and greatly improve the glue application effect.
[0020] Further reference Figure 5 A vertical plate 28 is slidably installed inside the mounting frame 16. A counterweight 30 is fixedly installed at the bottom of the vertical plate 28. A brush 31 that abuts against the glue coating roller 17 is fixedly installed at the top of the counterweight 30. When the glue coating roller 17 rotates, the brush 31 abuts against the glue coating roller 17, allowing the brush 31 to scrape the glue coating roller 17, so that the glue is applied more evenly to the surface of the glue coating roller 17 and enters the groove of the glue coating roller 17. When applying glue to the cardboard, it is more even and effectively improves the glue coating effect.
[0021] Further reference Figure 1 , Figure 5 , Figure 6 and Figure 7The upper surface of the base 10 has two symmetrically arranged sliding grooves 24 on both sides of the placement groove 11. Support blocks 25 are fixedly installed on the bottom of both sides of the mounting frame 16. Springs 26 are fixedly installed inside the support blocks 25. Roller assemblies 27 that slide inside the support blocks 25 are fixedly installed on the outer ends of the springs 26. The roller assembly 27 includes rollers and a frame for fixing the rollers. A limit block 29 is fixedly installed on the top of the vertical plate 28, and a connecting rod 32 is fixedly installed between the outer side of the vertical plate 28 and the frame of the roller assembly 27. When the cardboard is coated with glue, the mounting frame 16 and the glue roller 17 move downward, thereby driving the connected support blocks 25 and roller assembly 27 to move downward as well, so that the frame of the roller assembly 27 slides inside the sliding grooves 24 during glue application. This improves the stability of the roller assembly 27 during glue application. The rollers of the roller assembly 27 rotate inside the slide groove 24, reducing friction between the slide grooves and thus extending its service life. During glue application, the frame of the roller assembly 27 slides into the support block 25 and compresses the spring 26. As the support block 25 moves upward, it drives the connecting rod 32, which in turn moves the vertical plate 28 upward, disengaging the brush 31 from the glue application roller 17 and preventing interference with the glue application. After glue application, the mounting frame 16 and the glue application roller 17 are raised. The compressed spring 26 resets the roller assembly 27, and the weight of the counterweight 30 pulls the brush 31 back to its original position until the limit block 29 abuts against the mounting frame 16, facilitating the next glue application.
[0022] Further reference Figure 2 Side plates 34 are fixedly installed on both sides of the collection box 33 on the upper surface of the base 10. A scraper 35 is fixedly installed on the top of the side plates 34. After the glue is applied, the glue roller 17 returns to the initial state. At this time, the blade of the scraper 35 abuts against the surface of the glue roller 17. The glue roller 17 is rotated by the motor 18, so that the scraper 35 scrapes off the remaining glue on the surface of the glue roller 17 and falls into the collection box 33 below for recycling. At the same time, it ensures that the glue layer transferred to the cardboard is uniform in thickness during the next glue application, avoiding excessive or insufficient glue in some areas, and effectively improving the glue application quality.
[0023] Finally, it should be noted that the connection and fixing of each part of the cardboard gluing device for advertising production of this utility model can be achieved by conventional mechanical connection structure, and the control system and connection method required between multiple electrical components and driving components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as it can achieve its beneficial effect or the specific actions in the above work, it can be implemented.
