Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a cardboard composite gluing and pressing device. Background Technique

[0002] When processing cardboard, in order to process cardboard with a specific thickness, multiple layers of cardboard need to be stacked in sequence for pressing operations to laminate the cardboard together, thereby increasing the thickness of the cardboard and improving its hardness. Using a pressing device to press multiple layers of cardboard can better complete the pressing operation. Currently, during pressing, the cooperation of two pressing rollers is mostly used to complete the pressing of the laminated cardboard, and the pressing effect mainly depends on the gluing effect. When too much glue is applied, it will cause wrinkles in the laminated cardboard after being pressed by the two pressing rollers, increasing the defective rate of the laminated cardboard. However, the existing gluing and pressing equipment cannot handle the excess glue during use. Therefore, a cardboard composite gluing and pressing device is needed to meet the requirements. Content of the Utility Model

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Embodiment 1: Refer to Figure 1-6 , a cardboard composite glue applying and pressing device, including a bottom plate 1 and a fixed plate 2. The fixed plate 2 is fixed on the bottom plate 1. The fixed plate 2 is in an inverted C-shaped structure. Two pressing rollers 3 are symmetrically and rotatably arranged on the fixed plate 2. Two glue applying rollers 4 are symmetrically and rotatably arranged on the fixed plate 2 on one side of the two pressing rollers 3. Driving mechanisms are fixed on both the two glue applying rollers 4 and the two pressing rollers 3. The two driving mechanisms are both fixed on the fixed plate 2. The two driving mechanisms drive the two glue applying rollers 4 and the two pressing rollers 3 to rotate respectively. And the two pressing rollers 3 press the cardboard after glue application on the two glue applying rollers 4 and the inner and outer layer cardboard, so that the cardboard after glue application is bonded inside the inner and outer layer cardboard. At the same time, the rotation of the two glue applying rollers 4 and the two pressing rollers 3 can drive the movement of the cardboard to be glued, the inner and outer layer cardboard, and the composite cardboard.

[0022] A first glue storage mechanism and a second glue storage mechanism are respectively fixed on the fixed plate 2 and the bottom plate 1. The two glue applying rollers 4 are continuously glued by using the first glue storage mechanism and the second glue storage mechanism. A first scraper 8 and a second scraper 11 are respectively arranged on the two glue applying rollers 4 in an inclined and sliding manner. The first scraper 8 and the second scraper 11 are respectively fixed on the second glue storage mechanism and the first glue storage mechanism. The first scraper 8 and the second scraper 11 can scrape off the excess glue on the two glue applying rollers 4, ensuring that the glue amount on the two glue applying rollers 4 when gluing the cardboard to be glued will not be excessive, and further ensuring that the composite cardboard after being pressed by the two pressing rollers 3 will not wrinkle due to excessive glue.

[0023] During use, the first glue storage mechanism and the second glue storage mechanism apply glue to the two glue rollers 4 continuously. The two rotating glue rollers 4 apply the glue onto the cardboard that needs to be glued. Then, the two rotating pressing rollers 3 press the glued cardboard and the inner and outer layers of cardboard together, enabling the glued cardboard to adhere inside the inner and outer layers of cardboard. When the two glue rollers 4 are rotating, the first scraper 8 and the second scraper 11 are used to scrape off the excess glue on the two glue rollers 4, ensuring that the amount of glue applied to the cardboard by the two glue rollers 4 is not excessive.

[0024] Embodiment 2: On the basis of Embodiment 1, referring to Figure 1 、 2 、4, 5 and 6, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the second glue storage mechanism includes a second glue box 7. The second glue box 7 is fixed on the bottom plate 1. One of the glue rollers 4 is inserted into the second glue box 7. The glue roller 4 picks up the glue in the second glue box 7 during rotation. A first adjustment mechanism is jointly fixed on the second glue box 7 and the first scraper 8. The first adjustment mechanism can adjust the distance between the first scraper 8 and the glue roller 4, and thus can adjust the thickness of the glue applied by the glue roller 4. The first adjustment mechanism includes a first electric telescopic rod 10. The first electric telescopic rod 10 is fixed on the second glue box 7. A first connecting plate 9 is fixed on the first electric telescopic rod 10. The first connecting plate 9 is fixed on the first scraper 8. The first electric telescopic rod 10 can adjust the distance between the first scraper 8 and the lower glue roller 4 through the first connecting plate 9.

[0025] The first glue storage mechanism includes a first glue box 5. The first glue box 5 is fixedly penetrated on the fixing plate 2. A plurality of glue spraying nozzles 6 are equidistantly and communicatively fixed on the first glue box 5. The plurality of glue spraying nozzles 6 spray the glue in the first glue box 5 onto the upper glue roller 4. A second adjustment mechanism is jointly fixed on the first glue box 5 and the second scraper 11. The second adjustment mechanism is used to adjust the distance between the second scraper 11 and the upper glue roller 4.

[0026] The second adjustment mechanism includes two second electric telescopic rods 14. The two second electric telescopic rods 14 are both fixed on the first glue box 5. Second connecting plates 13 are fixed on the two second electric telescopic rods 14. A recycling box 12 is jointly fixed on the two second connecting plates 13. The recycling box 12 is fixed on the second scraper 11. The excess glue scraped off by the second scraper 11 flows along the second scraper 11 into the recycling box 12, preventing the excess glue scraped off by the second scraper 11 from contaminating the cardboard that needs to be glued and enabling the recycling of the excess glue. A pump 15 is fixed in the recycling box 12. A pipeline 16 is fixed on the pump 15. The end of the pipeline 16 away from the pump 15 is inserted into the first glue box 5. The pump 15 recycles the glue recovered in the recycling box 12 back into the first glue box 5.

[0027] In use, with the assistance of the first electric telescopic rod 10 and the two second electric telescopic rods 14, the distances between the second scraper 11 and the first scraper 8 and the two glue rollers 4 can be adjusted, so that different thicknesses of glue can be present on the two glue rollers 4, meeting the requirements for different amounts of glue when bonding different cardboard sheets. Moreover, the excess glue scraped off by the first scraper 8 is recovered into the second glue box 7, and the glue scraped off by the second scraper 11 is collected into the recovery box 12 and finally recovered into the first glue box 5 through the pump 15 and the pipeline 16, thereby avoiding waste of glue.

[0028] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
