Description

Technical Field

[0001] This utility model relates to the field of cardboard box manufacturing technology, and more specifically, to a cardboard coating device for cardboard box production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of various types of paper are different, and the paper produced by different manufacturers also varies in color and texture. Cardboard boxes are currently a widely used packaging method in commodity production. Cardboard boxes are made by folding and connecting cardboard. During the production of cardboard boxes, the surface of the cardboard needs to be coated with glue.

[0003] Currently, gluing of cardboard is generally done manually using a gluing roller. This is not only time-consuming and labor-intensive, but also results in uneven glue application. This reduces cardboard production efficiency, affects the final product quality, and leads to significant glue waste. Furthermore, after gluing, a large amount of glue remains on the outside of the roller. If this glue is not scraped off, it will not only affect the gluing effect on the cardboard but also cause further glue waste. Utility Model Content

[0004] The purpose of this utility model is to provide a cardboard gluing device for carton production, including a base, and further comprising:

[0005] A support frame is fixedly connected to the upper surface of the base;

[0006] Support plates are symmetrically arranged on the upper surface of the base. A glue storage basin is fixedly connected between the two support plates. A drive motor is fixedly connected to the outside of one of the support plates. The output shaft of the drive motor is fixedly connected to a glue application roller through a coupling. The other end of the glue application roller is rotatably connected to the outside of the other support plate. A glue discharge pipe is connected to the bottom of the glue storage basin through a solenoid valve.

[0007] A coating assembly is disposed outside the glue storage basin and is used to coat the glue on the outside of the coating roller, thereby making the glue on the outside of the coating roller more uniform.

Herringbone anti-slip grooves are equally spaced on the bottom of the multiple anti-slip pads.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this cardboard coating device for carton production, a coating component and a scraping component are installed. When the cardboard needs to be coated, the cardboard is placed between the coating roller and the limiting roller, and glue is added to the glue storage basin. At this time, the drive motor starts running, driving the coating roller to rotate synchronously. During the rotation of the coating roller, the glue inside the glue storage basin will adhere to it. At this time, the cardboard can be effectively coated by the coating roller. During the rotation of the coating roller, the coating component can effectively coat the glue on the surface of the coating roller, thereby improving the uniformity of the glue on the outside of the coating roller. When it is necessary to scrape off the glue on the outside of the coating roller, the scraping component starts running. At this time, the scraping component can effectively scrape off the glue on the outside of the coating roller, thereby preventing the glue from affecting the normal coating effect of the coating roller, and avoiding glue waste, saving time and labor.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 7 As shown, this embodiment provides a cardboard coating device for carton production, including a base 1, and further comprising:

[0028] Support frame 2 is fixedly connected to the upper surface of base 1;

[0029] Support plates 3 are symmetrically arranged on the upper surface of the base 1. A glue storage basin 6 is fixedly connected between the two support plates 3. A drive motor 4 is fixedly connected to the outside of one of the support plates 3. The output shaft of the drive motor 4 is fixedly connected to a glue application roller 5 through a coupling. The other end of the glue application roller 5 is rotatably connected to the outside of the other support plate 3. A glue discharge pipe 25 is connected to the bottom of the glue storage basin 6 through a solenoid valve 24.

[0030] The coating assembly is located outside the glue storage basin 6 and is used to coat the glue on the outside of the glue coating roller 5, thereby making the glue on the outside of the glue coating roller 5 more uniform.

[0031] The C-shaped plate 8 is located below the support frame 2, and the internal part of the C-shaped plate 8 is rotatably connected to the limit roller 7;

[0032] The scraping component is located outside the glue storage basin 6 and is used to scrape and collect the glue outside the glue application roller 5.

[0033] The working principle is as follows: When it is necessary to coat the cardboard with glue, simply place the cardboard between the coating roller 5 and the limiting roller 7, and then add glue to the glue storage basin 6. At this time, the drive motor 4 starts running, driving the coating roller 5 to rotate synchronously. During the rotation of the coating roller 5, the glue will adhere to the glue inside the glue storage basin 6. At this time, the coating roller 5 can effectively coat the cardboard with glue. During the rotation of the coating roller 5, the coating component can effectively coat the glue on the surface of the coating roller 5, thereby improving the uniformity of the glue on the outside of the coating roller 5. When it is necessary to scrape off the glue on the outside of the coating roller 5, the scraping component starts running. At this time, the scraping component can effectively scrape off the glue on the outside of the coating roller 5, thereby preventing the glue from affecting the normal coating effect of the coating roller 5, and avoiding glue waste, saving time and effort.

[0034] To improve the adhesion between the limiting roller 7 and the coating roller 5 and the cardboard, the bottom of the support frame 2 is symmetrically provided with abutment sleeves 9. The inside of the abutment sleeve 9 is provided with abutment plate 26. The bottom of the abutment plate 26 is fixedly connected with a movable rod 10. The bottom of the abutment sleeve 9 is provided with a guide groove for the movable rod 10 to move. The upper surface of the abutment plate 26 is fixedly connected with an abutment spring 27. The other end of the abutment spring 27 is fixedly connected to the top of the inside of the abutment sleeve 9. The bottom ends of the two movable rods 10 are fixedly connected to the upper surface of the shaped plate 8. Through the abutment plate 26, the abutment spring 27 and the movable rod 10, the limiting roller 7 can always be in contact with the upper surface of the cardboard, thereby effectively improving the adhesion between the limiting roller 7 and the coating roller 5 and the cardboard, and thus effectively improving the coating effect of the coating roller 5 on the cardboard.

[0035] Considering that when using the coating roller 5 to coat the cardboard, it is necessary to evenly apply the glue to the outside of the coating roller 5, the coating assembly includes a fixing plate 19 fixedly connected to the outside of the glue storage basin 6. A mounting plate 20 is fixedly connected to the upper surface of the fixing plate 19. A guide groove for the connecting plate 21 to move is opened on the upper surface of the mounting plate 20. The connecting plate 21 and the mounting plate 20 are fixedly connected by bolts. A coating brush 22 is fixedly connected to the upper surface of the connecting plate 21. During the rotation of the coating roller 5, the coating brush 22 can effectively coat the glue on the outside of the coating roller 5, thereby effectively improving the uniformity of the glue on the outside of the coating roller 5. When it is necessary to disassemble, clean or replace the coating brush 22, simply unscrew the bolts and pull the connecting plate 21 out of the guide groove on the upper surface of the mounting plate 20. At this time, the coating brush 22 can be disassembled, which makes it convenient for the staff to replace or clean it.

[0036] In order to effectively scrape off the glue on the outside of the coating roller 5, the scraping assembly includes an outer plate 11 fixedly connected to the outside of the glue storage basin 6. An upper plate 12 is fixedly connected to the upper surface of the outer plate 11. Electric telescopic rods 13 are symmetrically arranged on one side of the upper plate 12. The telescopic ends of the two electric telescopic rods 13 are fixedly connected to a moving plate 14. A scraper 15 is fixedly connected to the upper surface of the moving plate 14. When it is necessary to scrape off the glue on the outside of the coating roller 5, the electric telescopic rods 13 start to run, driving the moving plate 14 to move synchronously. The moving plate 14 then drives the scraper 15 to move synchronously. When the scraper 15 comes into contact with the coating roller 5, the glue on the outside of the coating roller 5 can be scraped off by the scraper 15.

[0037] In order to effectively collect and process the glue scraped off the outside of the glue coating roller 5, a positioning frame 16 is fixedly connected to the upper surface of the outer plate 11. The positioning frame 16 is equipped with a collection frame 17. During the rotation of the glue coating roller 5, the scraper 15 can effectively scrape off the glue on the outside of the glue coating roller 5. At this time, the scraped glue will slide down into the collection frame 17 through the scraper 15. The collection frame 17 can effectively collect and process the glue, thereby effectively preventing glue waste. When it is necessary to process the glue in the collection frame 17, simply pull the collection frame 17 out of the positioning frame 16.

[0038] In addition, to prevent displacement of the device during operation, the bottom of the outer panel 11 is symmetrically provided with support feet 18. Anti-slip pads 23 are glued to the bottom of the two support feet 18 and the bottom of the base 1. Herringbone anti-slip grooves are equally spaced on the bottom of the multiple anti-slip pads 23. The anti-slip pads 23 and the herringbone anti-slip grooves can effectively play an anti-slip role, thereby preventing displacement of the device during operation and affecting the glue coating effect and efficiency of the cardboard.
