Description

Technical Field

[0001] This utility model relates to the field of gluing device technology, specifically to a gluing device for corrugated cardboard lamination. Background Technology

[0002] The gluing device for corrugated board lamination is a key piece of equipment in the corrugated board production process. Its core function is to accurately and evenly apply adhesive during the corrugated board lamination process, so that different layers of board can be firmly bonded together to form corrugated board with specific strength and structure.

[0003] The existing technology has the following problems: The existing device cannot apply glue to the corrugated paper by moving it back and forth during use. The corrugated paper has height differences between its peaks and valleys, and the paper may also have slight left and right offsets. When applying glue along a fixed trajectory, some peaks may not be glued or the amount of glue may be too small, resulting in insufficient bonding of these parts during lamination. In addition, the existing device cannot stir the glue solution inside the storage tank. The glue used for corrugated paper is mostly water-based and contains solid components such as starch and fillers. If it is left to stand for a long time without stirring, the solid particles will settle to the bottom of the storage tank due to gravity, forming sediment. This causes the upper layer of glue to become thinner, while the lower layer becomes too thick or even clumps together. Utility Model Content

[0004] This invention provides a gluing device for corrugated cardboard lamination to solve the problems existing in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A gluing device for corrugated cardboard lamination includes a base, a support column fixedly connected to the upper side of the base, a first motor fixedly connected to the left side of the support column, a material roller fixedly connected to the output shaft of the first motor, two fixed columns fixedly connected to the upper side of the base, a liquid storage tank fixedly connected to the left side of the left fixed column, a liquid pump fixedly connected to the upper side of the liquid storage tank, an input pipe of the liquid pump fixedly connected to the liquid storage tank, a corrugated pipe fixedly connected to the output pipe of the liquid pump, and a fixed frame fixedly connected to the opposite faces of the two fixed columns.

[0015] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments: like Figure 1 As shown, this utility model provides a gluing device for corrugated cardboard lamination, including a base 1, a support column 3 fixedly connected to the upper side of the base 1, a first motor 4 fixedly connected to the left side of the support column 3, a material roller 5 fixedly connected to the output shaft of the first motor 4, two fixed columns 6 fixedly connected to the upper side of the base 1, a liquid storage tank 2 fixedly connected to the left side of the left fixed column 6, a liquid pump 7 fixedly connected to the upper side of the liquid storage tank 2, an input pipe of the liquid pump 7 fixedly connected to the liquid storage tank 2, and a corrugated pipe 9 fixedly connected to the output pipe of the liquid pump 7. The opposite surfaces of the two fixed columns 6 are... A fixed frame 8 is fixedly connected. When the device is working, the first motor 4 starts, and its output shaft drives the material roller 5 to rotate. The material roller 5 is used to transport the corrugated cardboard to be coated, so that it enters the coating area smoothly. The liquid storage tank 2 stores the adhesive required for corrugated cardboard lamination. The liquid pump 7 draws the adhesive from the liquid storage tank 2 through the input pipe, and then delivers it to the corrugated pipe 9 through the output pipe. The corrugated pipe 9 guides the adhesive into the moving frame 10 to provide the adhesive source for the subsequent coating process. The fixed frame 8 is fixed between two fixed columns 6 to provide support and installation foundation for the movement of the moving frame 10.

[0016] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, a support plate 12 is fixedly connected to the right side of the right-end fixed column 6, a second motor 13 is fixedly connected to the front side of the support plate 12, a turntable 20 is fixedly connected to the output shaft of the second motor 13, a rotating plate 14 is rotatably connected to the eccentric part of the turntable 20, a moving column 15 is rotatably connected to the other end of the rotating plate 14, a moving frame 10 is fixedly connected to the left end of the moving column 15, multiple glue-applying heads 11 are fixedly connected to both the upper and lower sides of the inner surface of the moving frame 10, the end of the corrugated pipe 9 away from the liquid pump 7 is fixedly connected to the moving frame 10, two limiting blocks 16 are fixedly connected to both the upper and lower sides of the moving frame 10, limiting grooves 17 are opened on both the upper and lower sides of the inner surface of the fixed frame 8, limiting rods 18 are fixedly connected to the inner surface of the limiting grooves 17, and the outer wall of the limiting rods 18 is slidably connected to the limiting blocks 16. After the motor 13 starts, its output shaft drives the turntable 20 to rotate. Since one end of the rotating plate 14 is rotatably connected to the eccentric part of the turntable 20, when the turntable 20 rotates, it will drive the moving column 15 to move back and forth through the rotating plate 14. The moving column 15 is fixedly connected to the moving frame 10. Therefore, the moving frame 10 moves back and forth synchronously with the moving column 15. The limiting blocks 16 on the upper and lower sides of the moving frame 10 are fitted onto the limiting rods 18 in the limiting grooves 17 of the fixed frame 8. The limiting blocks 16 slide along the limiting rods 18, which guides and limits the movement of the moving frame 10, ensuring its stable reciprocating movement. During the movement, the multiple glue application heads 11 on the upper and lower sides of the inner surface of the moving frame 10 evenly apply the glue delivered by the corrugated pipe 9 to the surface of the corrugated cardboard, realizing reciprocating glue application, adapting to the flute peaks and valleys of the corrugated paper, and avoiding missed application and insufficient glue.

[0017] like Figure 4-6As shown, this utility model provides a technical solution: Preferably, a feeding pipe 19 is fixedly connected to the rear side of the liquid storage tank 2, a partition 21 is fixedly connected to the inner surface of the liquid storage tank 2, a third motor 22 is fixedly connected to the upper side of the liquid storage tank 2, a threaded rod 23 is fixedly connected to the output end of the third motor 22, a support plate 29 is fixedly connected to the upper side of the partition 21, a guide post 28 is fixedly connected to the rear side of the support plate 29, a lifting plate 24 is threadedly connected to the outer wall of the threaded rod 23, and the upper side of the lifting plate 24 passes through... An opening is provided, and a rotating shaft 25 is rotatably connected to the inner surface of the opening. A stirring mechanism 26 is fixedly connected to the lower end of the rotating shaft 25. An annular groove 27 is provided on the outer wall of the rotating shaft 25. The outer wall of the guide post 28 is slidably connected to the annular groove 27. A limit ring 30 is fixedly connected to the inner surface of the opening. An annular groove 31 is provided at the upper end of the outer wall of the rotating shaft 25. The outer wall of the limit ring 30 is rotatably connected to the annular groove 31. After the third motor 22 is started, its output end drives the threaded rod 23 to rotate. The threaded lifting plate 24 moves up and down under the action of the threads. The rotating shaft 25 on the lifting plate 24 moves up and down synchronously with the lifting plate 24. At the same time, the annular groove 27 on the outer wall of the rotating shaft 25 slides with the guide post 28 on the support plate 29. When the rotating shaft 25 moves up and down, the guide post 28 exerts a force on the annular groove 27, forcing the rotating shaft 25 to rotate. The stirring mechanism 26 at the lower end of the rotating shaft 25 moves up and down and rotates simultaneously with the rotating shaft 25, thus agitating the adhesive in the storage tank 2. With thorough stirring, the limiting ring 30 is rotatably connected to the annular groove 31 of the rotating shaft 25, ensuring that the rotating shaft 25 rotates stably within the opening of the lifting plate 24 and preventing it from deviating. Through the compound movement of the stirring mechanism 26, the adhesive in the storage tank 2 is thoroughly mixed, preventing solid particles from settling and ensuring that the adhesive concentration is uniform. The feeding pipe 19 on the rear side of the storage tank 2 is used to add adhesive raw materials into the storage tank 2. The partition 21 divides the interior of the storage tank 2, providing reasonable space for the movement of the stirring mechanism 26.

[0018] The working principle of the gluing device used for corrugated cardboard lamination will be explained in detail below.

[0019] like Figure 1-6As shown, after the second motor 13 starts, its output shaft drives the turntable 20 to rotate. Since one end of the rotating plate 14 is rotatably connected to the eccentric part of the turntable 20, when the turntable 20 rotates, it will drive the moving column 15 to move back and forth through the rotating plate 14. The moving column 15 is fixedly connected to the moving frame 10, so the moving frame 10 moves back and forth synchronously with the moving column 15. The limiting blocks 16 on the upper and lower sides of the moving frame 10 are fitted onto the limiting rods 18 in the limiting grooves 17 of the fixed frame 8. The limiting blocks 16 slide along the limiting rods 18, which guides and limits the movement of the moving frame 10, ensuring its stable reciprocating movement. During the movement, the multiple glue applicators 11 on the upper and lower sides of the inner surface of the moving frame 10 evenly apply the glue delivered by the corrugated pipe 9 to the surface of the corrugated cardboard, realizing reciprocating glue application, adapting to the peak and valley structure of the corrugated paper, and avoiding missed application and insufficient glue. After the third motor 22 starts, its output end drives the threaded rod 23 to rotate, and the threaded rod 23 is threadedly connected to the threaded rod 23. The lifting plate 24 moves up and down under the action of the thread. The rotating shaft 25 on the lifting plate 24 moves up and down synchronously with the lifting plate 24. At the same time, the annular inclined groove 27 on the outer wall of the rotating shaft 25 slides and engages with the guide post 28 on the support plate 29. When the rotating shaft 25 moves up and down, the guide post 28 exerts a force on the annular inclined groove 27, forcing the rotating shaft 25 to rotate. The stirring mechanism 26 at the lower end of the rotating shaft 25 moves up and down and rotates simultaneously with the rotating shaft 25, which fully stirs the adhesive in the storage tank 2. The limiting ring 30 is rotatably connected to the annular groove 31 of the rotating shaft 25 to ensure that the rotating shaft 25 rotates stably within the opening of the lifting plate 24 and avoids its deviation. Through the compound movement of the stirring mechanism 26, the adhesive in the storage tank 2 is fully mixed to prevent solid particles from settling and to ensure that the adhesive concentration is uniform. The feeding pipe 19 on the rear side of the storage tank 2 is used to add adhesive raw materials into the storage tank 2. The partition 21 divides the interior of the storage tank 2 to provide reasonable space for the movement of the stirring mechanism 26.

[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
