Description

Technical Field

[0001] The present application relates to the field of cardboard processing, and in particular to a cardboard bonding device. Background Art

[0002] Cardboard, also known as paperboard, is a thick sheet of paper made from various pulps and interwoven with fibers. It's typically made from various plant fibers, though non-plant fibers may also be incorporated. It's manufactured on a cardboard machine. During the production process, glue is applied to the base cardboard layer according to production needs, and then bonded to the other layers. After laminating, the glue applied to the cardboard may overflow from the edges. If this overflow isn't promptly removed, it can cause the sheets to stick together when stacked, making them impossible to separate.

[0003] A cardboard bonding device is now provided. Utility Model Content

[0050] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0051] Reference Figure 1-Figure 3 A cardboard bonding device includes: a cardboard pressing machine 11, a bracket 12, a beam 14, a slider 16, a scraper 17, a first motor 18, a screw rod 19, a scraping block 21, and a connecting block 20.

[0052] Two brackets 12 are symmetrically mounted on one side of the cardboard press 11 and are erected on the ground. The ends of the crossbeam 14 are fixedly connected to the brackets 12 on both sides. A conveyor belt 13 is mounted on the brackets 12. One end of the conveyor belt 13 extends to the side of the cardboard press 11. One end of the conveyor belt 13 is flush with and in smooth contact with the discharge port of the cardboard press 11. The crossbeam 14 is located directly above the conveyor belt 13.

[0053] Two sliders 16 are provided and symmetrically slidably connected to the crossbeam 14. Two scrapers 17 are provided and fixedly connected to the bottom walls of the two sliders 16, and the blade tips of the two scrapers 17 are arranged opposite each other. Two first motors 18 are provided and fixedly connected to the two sliders 16, and two screw rods 19 are provided and fixedly connected to the output shafts of the two first motors 18. Two scraper blocks 21 are provided and slidably connected to the two scrapers 17. The scrapers 17 pass through the scraper blocks 21 and are in sliding contact with the scrapers 17. Two connecting blocks 20 are provided and fixedly connected to the two scraper blocks 21. The connecting blocks 20 are threadedly connected to the screw rods 19. The two scrapers 17 are suspended directly above the conveyor belt 13.

[0054] In order to drive the slider 16 to move, two sets of driving components are provided. The two sets of driving components are respectively provided on the two sliders 16. The driving components include: a second motor 22, a gear 23, and a rack 15;

[0055] The second motor 22 is fixedly connected to the slider 16, the gear 23 is fixedly connected to the output shaft of the second motor 22, and the rack 15 is fixedly connected to the bottom wall of the beam 14. The gear 23 meshes with the rack 15. The rack 15 passes through the slider 16 and the slider 16 slides relative to the rack 15.

[0056] In order to dry the glue, a drying unit is provided, which includes a drying box 24, a fan 26, and an electric heating tube 27;

[0057] A drying box 24 is fixedly connected to the bracket 12 and defines an upwardly opening drying chamber 25. Multiple fans 26 are evenly spaced and mounted on the walls of the drying chamber 25. Multiple electric heating tubes 27 are evenly spaced and mounted on the top wall of the drying box 24, with fans 26 positioned below the electric heating tubes 27. The drying box 24 is located below the other end of the conveyor belt 13.

[0058] Working or installation process:

[0059] After the cardboard is bonded and pressed by the cardboard pressing machine 11, the glue applied to the cardboard is squeezed and may overflow, and the glue overflows from the edge of the cardboard. The pressed cardboard slides out of the discharge port of the cardboard pressing machine 11 and slides smoothly onto the conveyor belt 13. The distance between the two scrapers 17 is set in advance according to the width of the cardboard, and the two second motors 22 are started, and the two second motors 22 are started in forward and reverse directions respectively. The output shaft of the second motor 22 drives the gear 23 to rotate. The gear 23 meshes with the rack 15 and drives the slider 16 to move. The slider 16 moves along the extension direction of the rack 15 and the two sliders 16 move toward each other. The slider 16 drives the scraper 17 to move, and the distance between the blade tips of the two scrapers 17 is made the same as that of the cardboard.

[0060] When the pressed cardboard slides onto the conveyor belt 13, the conveyor belt 13 starts to transport the cardboard. The tip of the scraper 17 slides in contact with the edge of the cardboard. At this time, the glue overflowing from the edge of the cardboard has not yet hardened, so the tip of the scraper 17 scrapes off the glue on the edge of the cardboard without affecting the conveyor belt 13 to transport the cardboard.

[0061] When the cardboard passes between the two scrapers 17, the scrapers 17 scrape off the glue on the edge of the cardboard, and the cardboard is continuously conveyed by the conveyor belt 13 and conveyed to the side of the conveyor belt 13 away from the cardboard pressing machine 11. At this time, the electric heating tube 27 is started, the electric heating tube 27 is heated, and the fan 26 is started. The fan 26 generates an upward airflow and blows the heat generated by the electric heating tube 27 upward, so that the cardboard conveyed to the top of the drying box 24 is dried, thereby accelerating the bonding and drying of the cardboard;

[0062] When a cardboard passes between the two scrapers 17, the first motor 18 is started, and the output shaft of the first motor 18 drives the screw 19 to rotate. The screw 19 rotates and is threadedly connected to the connecting block 20, thereby driving the connecting block 20 to move from top to bottom along the extension direction of the screw 19. The connecting block 20 drives the scraping block 21 to move from top to bottom. The scraping block 21 scrapes off the glue attached to the tip of the scraper 17. Then the first motor 18 is started in the reverse direction. The first motor 18 drives the scraping block 21 to move from bottom to top until the scraping block 21 is in contact with the bottom wall of the slider 16, and the first motor 18 stops working. At this time, the second cardboard passes between the two scrapers 17, and the scraper 17 scrapes off the overflowing glue on the edge of the cardboard again.

[0063] Repeat the above steps until all the cardboards are glued together.

[0064] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
