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 process of transforming advertising concepts into works of art through design and other means based on the purpose and needs of the product. In this process, gluing equipment is often used to apply glue to the advertising cardboard to achieve a firm bond.

[0003] In the prior art, Chinese utility model patent CN222093842U discloses a cardboard coating device for advertising production, including an anti-slip mat, a support foot installed at the top of the anti-slip mat, a housing installed inside the support foot, and a second stirring shaft installed inside the housing. This utility model utilizes a second gear installed at the bottom of a second motor. The second motor drives the second gear to rotate, which in turn drives a first gear to rotate. The first gear then drives the second stirring shaft to rotate, which in turn drives a second stirring blade to rotate. The first stirring shaft passes through the second stirring shaft. The first motor's operation causes the first stirring shaft to rotate, which in turn drives the first stirring blade to rotate. The rotation of both the first and second stirring blades stirs the adhesive inside the housing, preventing it from solidifying. This achieves the purpose of facilitating the stirring of the adhesive inside the housing in the cardboard coating device for advertising production.

[0004] In existing technologies, stirring blades are used to stir the adhesive and prevent it from solidifying, but there are still some shortcomings in its overall use:

[0005] Firstly, in the existing gluing equipment, many use gluing rollers to apply glue to the cardboard. However, most gluing equipment requires manual cleaning of the surface of the gluing roller after the gluing is completed. Manual cleaning delays work efficiency and is slow, which is not conducive to improving work efficiency.

[0006] Secondly, the aforementioned existing technology, which uses a limiting plate to press the cardboard onto the worktable, prevents glue from being applied to both ends of the cardboard during gluing. This necessitates additional processing steps, increasing production and time costs. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this invention provides a cardboard gluing device for advertising production. This invention solves the technical problem that manual cleaning of the gluing roller is slow and detrimental to work efficiency. Furthermore, it addresses the issue of the inability to apply glue to both ends of the cardboard, which increases costs during subsequent processing.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cardboard gluing device for advertising production, comprising a base, a slider slidably mounted above the base, a U-shaped mounting frame slidably mounted below the slider, movable grooves at both ends of the mounting frame, movable blocks slidably mounted inside the movable grooves, a spring fixedly mounted between the upper surface of the movable blocks and the lower surface of the movable grooves, a gluing roller rotatably mounted between the two movable blocks for rolling and pressing the cardboard after the glue has been sprayed, a scraper fixedly mounted on one side of the movable grooves, and a scraper blade fixedly mounted on one side of the scraper for scraping off the glue adhering to the surface of the gluing roller.

[0009] In the above-mentioned cardboard coating device for advertising production, a column is fixedly installed on the upper surface of the base, a top plate is fixedly installed on the top of the column, a groove is opened inside the top plate, a lead screw is rotatably installed inside the groove, the slider is threadedly engaged with the surface of the lead screw, and slides inside the groove.

[0010] In the aforementioned cardboard coating device for advertising production, a cylinder is fixedly mounted on the lower surface of the slider, and the output end of the cylinder is fixed to the upper surface of the mounting frame.

[0011] In the above-mentioned cardboard coating device for advertising production, a coating box is fixedly installed on the side of the mounting frame away from the scraper, and multiple coating heads are provided on one side of the coating box.

[0012] In the aforementioned cardboard coating device for advertising production, the upper surface of the base is equipped with a collection box that works in conjunction with the coating roller.

[0013] In the aforementioned cardboard coating device for advertising production, a back-shaped placement groove is provided on the upper surface of the base.

[0014] In the above-mentioned cardboard coating device for advertising production, a limiting groove is provided inside the placement groove, and multiple air holes are provided inside the limiting groove.

[0015] In the aforementioned cardboard gluing device for advertising production, the upper surface of the base is provided with a support platform inside the placement groove. After the cardboard is placed on the support platform, the cardboard is embedded in the placement groove and is flush with the upper surface of the base.

[0016] In summary, compared with the prior art, the cardboard gluing device for advertising production provided by this utility model has the following beneficial effects:

[0017] 1. This utility model, through the installation frame, moving block, glue roller, scraper and glue box, can pre-spray glue on the cardboard and then roll it, so that the glue can be evenly distributed on the surface of the cardboard, promote the glue to penetrate into the gap between the cardboard fibers, and reduce the risk of delamination by further compaction, thus improving the glue coating quality. At the same time, it can automatically scrape off the sticky glue, eliminating the need for manual cleaning and improving work efficiency.

[0018] 2. This utility model, through the setting of placement groove, limiting groove and air hole, can fix the cardboard with negative pressure, without the need to fix it from both ends of the cardboard, there are no dead corners in fixing, and it can ensure that the entire cardboard can be coated with glue without additional processing steps, thus reducing the cost of use.

Detailed Implementation

[0025] 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. Example 1:

[0026] refer to Figure 1 An adhesive coating device for cardboard in advertising production includes a base 10, with legs 11 fixedly installed on the lower surface of the base 10, and a support platform 12 for placing cardboard on the upper surface of the base 10.

[0027] Further reference Figure 1 and Figure 3 Two symmetrically arranged columns 17 are fixedly installed on the upper surface of the base 10. A top plate 18 is fixedly installed on the top of the columns 17. A groove 19 is opened in the middle of the top plate 18. A lead screw 20 is rotatably installed inside the groove 19. A drive servo motor 21 is fixedly installed on one side of the top plate 18. A slider 22, which is slidably disposed inside the groove 19, is threadedly engaged with the surface of the lead screw 20. In use, the output end of the servo motor 21 drives the lead screw 20 connected to it to rotate. When the lead screw 20 rotates clockwise, due to the threaded engagement between the slider 22 and the lead screw 20, the slider 22 slides to the right inside the groove 19 under the limit of the groove 19. Similarly, when the base 10 rotates counterclockwise, the slider 22 slides to the left inside the groove 19.

[0028] Further reference Figure 1 and Figure 2 A cylinder 23 is fixedly installed on the lower surface of the slider 22. A U-shaped mounting bracket 24 is fixedly installed at the output end of the cylinder 23. A support plate 25 is fixedly installed on one side of the mounting bracket 24. A glue-applying box 26 is fixedly installed on the upper surface of the support plate 25. A glue-applying device is externally connected to the top of the glue-applying box 26. The glue-applying device is existing technology and will not be described in detail in this solution. Multiple glue-applying heads 27 are provided on one side of the glue-applying box 26. When in use, the cylinder 23 is activated to push the mounting bracket 24 to move downward, thereby causing the support plate 25 and the glue-applying box 26 connected to it to also move downward, thereby causing the glue-applying heads 27 to move downward and pre-apply glue to the cardboard.

[0029] Specifically, when the lead screw 20 rotates clockwise, the slider 22 drives the cylinder 23 to move to the right. When the slider 22 moves to the end of the slide groove 19, the cylinder 23 drives the mounting frame 24 to move downward, so that the glue applicator 27 is located directly above the end of the cardboard and sprays glue onto the cardboard. At the same time, the lead screw 20 rotates counterclockwise, causing the slider 22 to move to the left, which also drives the glue applicator 27 to move to the left. This allows the entire cardboard to be sprayed from right to left, thus improving the performance of the cardboard.

[0030] Further reference Figure 2The mounting bracket 24 has movable slots 28 at both ends. Movable blocks 29 are slidably mounted inside the movable slots 28. A spring 30 is fixedly installed between the upper surface of the movable block 29 and the lower surface of the movable slot 28. A glue-applying roller 31 is rotatably mounted between the two movable blocks 29. A glue-applying motor 32 that drives the glue-applying roller 31 is fixedly installed on one side of the movable block 29. When the movable slot 28 moves the glue-applying head 27 downwards for spraying, the movable slot 28 also moves the glue-applying roller 31, causing the glue-applying roller 31 to press against the upper surface of the end of the support plate. This movement is achieved through the movable blocks 29. The glue-applying roller 31 slides inside the moving groove 28, and with the help of the spring 30, the spring 30 always supports the moving block 29, so that the glue-applying roller 31 can always press against the upper surface of the cardboard. When the glue-applying head 27 moves, the glue-applying motor 32 drives the glue-applying roller 31 to rotate. The glue-applying roller 31 rolls on the upper surface of the cardboard, rolling and pressing the sprayed glue. The spraying first ensures that the glue initially adheres to the cardboard, and the rolling pressure of the glue-applying roller 31 can further compact the glue layer, promote the glue to penetrate into the gaps between the cardboard fibers, reduce the risk of glue separation, and greatly improve the use effect.

[0031] Further reference Figure 3 and Figure 5 A scraper 34 is fixedly installed on the side of the mounting bracket 24 away from the glue coating box 26. A scraper 34 is fixedly installed on one side of the scraper 34 to abut against the glue coating roller 31. In the initial state, the scraper 34 abuts against the glue coating roller 31. When the glue coating roller 31 moves downwards to press the cardboard, it causes the glue coating roller 31 to move upwards a certain distance, as shown in the attached diagram. Figure 5 As shown, at this time, the scraper 34 separates from the coating roller 31, which does not hinder the normal operation of the coating roller 31. After the coating roller 31 finishes rolling the cardboard, the cylinder 23 drives the moving groove 28 to move upward, so that the coating roller 31 is separated from the cardboard. Under the action of the spring 30 resetting, the moving block 29 is pushed to move the coating roller 31 downward, so that the coating roller 31 comes into contact with the scraper 34 again. The coating roller 31 continues to rotate, and the scraper 34 scrapes off the glue on the surface of the coating roller 31, realizing the function of automatically removing glue from the coating roller 31. After the work is completed, the glue removal work of the coating roller 31 can be completed automatically without manual cleaning, avoiding glue sticking to the surface of the coating roller 31 and affecting the next coating effect.

[0032] Further reference Figure 1 A detachable collection box 35 is mounted on the left side of the upper surface of the base 10. The collection box 35 is located at the left end of the slide 19. When in use, after the glue-applying roller 31 has finished rolling the cardboard, it is located at the left end of the slide 19 and directly above the collection box 35. At this time, the glue removal work is carried out, so that the scraped glue falls into the collection box 35 for collection, avoiding the scraped glue from falling onto the upper surface of the base 10 and contaminating the workbench, thus improving the use effect. Example 2:

[0033] A cardboard gluing device for advertising production, based on Embodiment 1, is further illustrated in the following embodiment. Figure 1 and Figure 4 The upper surface of the base 10 has a U-shaped placement groove 13, and the inside of the placement groove 13 has a limiting groove 14. The support platform 12 is located inside the limiting groove 14. After the cardboard is placed on the support platform 12, the cardboard is embedded in the placement groove 13 and is flush with the upper surface of the base 10. The limiting groove 14 has an air hole 15. A bidirectional air pump 16 communicating with the air hole 15 is fixedly installed on the lower surface of the base 10. The bidirectional air pump 16 is prior art, referring to a pump that can both suck in and expel air, and will not be described in detail in this solution. In use, the cardboard is placed on the upper surface of the support platform 12 and embedded in the placement groove 13, and the cardboard seals the limiting groove 14. At this time, the bidirectional air pump 16 operates through the air hole 15. 5. Air is extracted, and through the principle of negative pressure, the air pressure presses the cardboard into the placement groove 13 for fixation. The placement groove 13 supports the cardboard, preventing the cardboard from being suspended when the glue coating roller 31 rolls the cardboard, which would cause the cardboard to bend, resulting in incomplete rolling and affecting the rolling quality. There is no need to press and fix the cardboard from both ends, so that there are no dead corners when the cardboard is glued, and the entire cardboard can be glued. There is no need for subsequent end processing, which greatly improves the use effect. After the cardboard is glued, the bidirectional air pump 16 will inject high-pressure gas into the air hole 15. By spraying the high-pressure gas onto the bottom of the cardboard, the cardboard can be pushed out of the placement groove 13 for easy handling by the staff.

[0034] It should be noted that the size of the placement groove 13 is set according to the length and width of the cardboard. When the cardboard is placed inside the placement groove 13, the outer periphery of the cardboard will abut against the inner wall of the placement groove 13. The layout of the air holes 15 is much smaller than the size of the cardboard, so the glue will not flow to the air holes 15 and cause blockage. In addition, the air holes 15 and the bottom surface of the placement groove 13 are treated with anti-stick coating. Even if glue sticks to the surface, it can be quickly removed with a scraper without affecting production efficiency. The position and number of air holes 15 can be set according to the actual situation. This solution does not impose any restrictions. At the same time, flexible suction cups or other auxiliary adsorption structures can also be installed on the surface of the air holes 15, as long as the cardboard can be adsorbed. This is also existing technology, and this solution does not impose too many restrictions.
