Description

Technical Field

[0001] This utility model relates to corrugated paper production equipment, and more specifically, to a corrugated cardboard composite device. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, generally divided into three-layer and five-layer corrugated paper. Corrugated paper is made by pressing the inner liner into a corrugated core paper with a corrugated roller, and then laminating it with a face paper with glue on one side to form corrugated cardboard. Currently, because the top face paper cannot be glued, corrugated cardboard can often only be laminated with one face paper before laminating with the other face paper, and it is not possible to laminate two face papers at the same time. This reduces the production efficiency of three-layer corrugated paper, so there is an urgent need to improve this. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a corrugated cardboard composite device. By setting a first gluing device and a second gluing device, the first face paper and the second face paper can be glued respectively, thereby realizing the simultaneous composite of the first face paper, the corrugated inner paper and the second face paper, which is beneficial to improving the production efficiency of corrugated paper.

[0008] Furthermore, the composite box is equipped with a push plate inside, which is moved by a cylinder. A baffle is provided on one side of the push plate, which can be inserted into or removed from the dispensing nozzle.

[0009] Furthermore, the lower part of the dispensing nozzle is provided with a platform, and the lower part of the platform is provided with multiple baffles arranged along the length of the platform.

[0010] Furthermore, the lower part of the entire platform is provided with a guide strip, the length of which is longer than the dispensing nozzle. Both ends of the guide strip are connected to a baffle through a bending section. The lower opening of the dispensing nozzle is located in the area enclosed by the guide strip, the bending section, and the baffle.

[0021] 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.

[0022] like Figures 1 to 4 As shown, this embodiment discloses a corrugated cardboard laminating device, including a laminating box 1. The laminating box 1 has a first opening 11 and a second opening 12 on both sides. A corrugated forming device (not shown in the figure) for liner paper is provided outside the first opening 11. The liner paper is formed into corrugated liner paper 9 by a corrugated roller 100 and then conveyed into the laminating box 1 through the first opening 11 for lamination.

[0023] The composite box 1 is equipped with a first gluing device 2 inside, a first conveying roller 14 is provided above the first gluing device 2, and a composite roller 18 is provided above the first conveying roller 14. The first gluing device 2 includes a first glue storage tank 21, and a glue inlet pipe 23 is provided on the side of the first glue storage tank 21. The glue inlet pipe 23 is connected to an external glue supply device (not shown in the figure). The external glue supply device can supply glue to the first glue storage tank 21. The glue used in this embodiment is starch water-based glue. The first glue storage tank 21 is equipped with a gluing roller 22, which is partially immersed in the glue. The gluing roller 22 can rotate. The composite box 1 is equipped with a pressure roller 15 inside, which is located above the gluing roller 22 and between the composite roller 18 and the first conveying roller 14.

[0024] The first sheet 7 is conveyed into the laminating box 1 from outside the second opening 12 through the first conveying roller 14. When the first sheet 7 passes between the pressure roller 15 and the gluing roller 22, the rotating roller 22 can coat the glue in the first glue storage tank 21 onto one side surface of the first sheet 7. The first sheet 7 coated with glue is conveyed through the laminating roller 18 and then bonded to the lower surface of the corrugated liner paper 9, which is also conveyed through the laminating roller 8. The bonding surface is the glued surface of the first sheet 7, thereby realizing the lamination of the first sheet 7 and the corrugated liner paper 9. After lamination, it is conveyed out of the laminating box 1 from the second opening 12. The pressure roller 15 and the gluing roller 22 rotate in the same direction, both clockwise. The mechanism that drives the pressure roller 15 and the gluing roller 22 to rotate is existing technology, and its specific structure will not be described in detail in this specification.

[0025] A second conveyor roller 16 is provided above the composite roller 18. A second gluing device is provided on the upper part of the composite box 1, and the second gluing device is located above the second conveyor roller 16. A third conveyor roller 17 is also provided inside the composite box 1. The composite roller 18 and the second gluing device are located between the second conveyor roller 16 and the third conveyor roller 17. The second gluing device includes a second glue storage tank 3, and a glue outlet 31 is provided at the lower part of the second glue storage tank 3. A narrow glue outlet 32 ​​is provided at the lower part of the glue outlet 31. The glue outlet 32 ​​is located inside the composite box 1. The second face paper 8 is located above the first face paper 7. The second face paper 8 is conveyed by the second conveyor roller 16 and enters the composite box 1 from the second opening 12, and then passes through the third conveyor roller 17. After being folded back, the paper enters the composite roller 18. The second face paper 8 is located in the horizontal section between the second conveyor roller 16 and the third conveyor roller 17. The second gluing device is located above this horizontal section and contains glue. The glue nozzle 32 passes through the third opening 13 at the top of the composite box 1. The lower end of the glue nozzle 32 is in clearance fit with the upper surface of the second face paper 8, allowing the glue to flow from the glue nozzle 32 onto the upper surface of the second face paper 8, thus achieving the gluing operation of the second face paper 8. After the second face paper 8 is glued, it is folded back by the third conveyor roller 17 and then laminated with the upper surface of the corrugated liner paper 8 by the composite roller 18, thereby achieving the simultaneous lamination of the first face paper 7, the corrugated liner paper 9, and the second face paper 8, which is beneficial to improving the production efficiency of three-layer corrugated paper.

[0026] The composite box 1 is equipped with two guide plates 19. The distance between the two guide plates 19 is the thickness of the first face paper 7, the second face paper 8 and the corrugated liner paper 9 after being composited. After the corrugated paper is composited, it is conveyed through the guide plates 19, which can make the first face paper 7, the second face paper 8 and the corrugated liner paper 9 bond more firmly.

[0027] The composite box 1 is equipped with a push plate 4, which is movable by a cylinder 5. A baffle 41 is provided on one side of the push plate 4. The baffle 41 can be inserted into or detached from the glue dispensing nozzle 32. The push plate 4 is connected to the telescopic rod of the cylinder 5. When glue needs to be applied, the baffle 41 detaches from the glue dispensing nozzle 32, and at the same time, the end of the baffle 41 away from the push plate 4 blocks the side wall of the glue dispensing nozzle 32. At this time, the glue dispensing nozzle 32 is open. When glue does not need to be applied, the cylinder 5 drives the push plate 4 to move, and the baffle 41 is inserted into the glue dispensing nozzle 32, thereby blocking the glue dispensing nozzle 32 and preventing glue from falling.

[0028] like Figure 3 and Figure 4 As shown, the lower part of the dispensing nozzle 32 is provided with a platform 33, and the lower part of the platform 33 is provided with multiple baffles 34 arranged along the length direction of the platform 33. The lower part of the platform 33 is provided with a guide strip 35, the length of the guide strip 35 is longer than the dispensing nozzle 32, and the two ends of the guide strip 35 are connected to a baffle 34 through a bending section 36. The lower opening of the dispensing nozzle 32 is located in the area enclosed by the guide strip 35, the bending section 36 and the baffle 34, and the lower part of the baffle 34 is lower than the lower part of the guide strip 35.

[0029] The platform 33 has a large area, and when the glue drips onto the surface of the second paper 8, the platform 33 can spread the glue evenly. However, the glue may not be completely spread evenly on the surface of the second paper 8. Therefore, by setting the glue guide strip 35, the distance between the lower part of the glue guide strip 35 and the upper surface of the second paper 8 is further reduced. Thus, the glue guide strip 35 can further smooth the glue on the surface of the second paper 8. Furthermore, by setting the bending section 36 and the baffle 34, the overflow of glue can be effectively reduced.

[0030] like Figure 1 As shown, it also includes an adhesive circulation device 6, which is connected to the first adhesive application device 2 and the second adhesive application device. The adhesive circulation device 6 includes a first pump body 61, a first connecting pipe 62, a second connecting pipe 63, and a second pump body 64. The inlet end of the first pump body 61 is connected to the first adhesive storage tank 21, and the outlet end is connected to the first connecting pipe 62. The other end of the first connecting pipe 62 is connected to the second adhesive storage tank 3. One end of the second connecting pipe 63 is connected to the second adhesive storage tank 3, and the other end is connected to the inlet end of the second pump body 64. The outlet end of the second pump body 64 is connected to the first glue storage tank 21 through a third connecting pipe 65. A glue outlet pipe 37 is provided in the second glue storage tank 3 along the length direction of the lower glue port 31. The glue outlet pipe 37 is connected to the first connecting pipe 62. A plurality of nozzles 38 facing the lower glue port 31 are provided on the side of the glue outlet pipe 37. The second glue storage tank 3 and the third connecting pipe 65 are connected through a fourth connecting pipe 66. The height of the connection end of the fourth connecting pipe 66 and the second glue storage tank 3 is higher than the height of the connection end of the second connecting pipe 63 and the second glue storage tank 3.

[0031] The first pump 61 operates, transporting the glue in the first glue storage tank 21 from the first connecting pipe 61 to the glue outlet pipe 37, and finally flowing into the second glue storage tank 3 from multiple nozzles 38. The nozzles 38 are designed along the length of the glue outlet 31, so that the glue can quickly and evenly fill the glue outlet 31. When the amount of glue in the second glue storage tank 3 is sufficient (when the glue level is higher than the connection end between the second connecting pipe 63 and the second glue storage tank 3), the second pump 64 transfers the glue in the second glue storage tank 3 from the third connecting pipe 63 and the fourth connecting pipe 64 to the first glue storage tank 21, thereby realizing the circulation of glue in the first glue storage tank 21 and the second glue storage tank 22.

[0032] A liquid level sensor or a pressure sensor can be installed in the second glue storage tank 3. When the liquid level is higher than the set high value of the liquid level sensor, the second pump body 64 works, and when the liquid level is lower than the set low value, the second pump body 64 stops working; or when the weight of the second glue storage tank 3 exceeds the set value, the second pump body 64 works, and when it is lower than the set value, the second pump body 64 stops working. The above sensors and control logic are all existing technologies commonly used in glue circulation, so they will not be described in detail in this specification.

[0033] By setting the fourth connecting pipe 66, the glue can be prevented from overflowing. By setting the glue circulation device 6, the second glue application device can be supplied.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
