Description

Technical Field

[0001] This application relates to the field of corrugated paper manufacturing equipment, and in particular to a corrugated board laminating device. Background Art

[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper in a waveform formed by processing through a corrugating roll. Generally, it is divided into two categories: single corrugated board and double corrugated board, and is divided into five types according to the size of the corrugation: A, B, C, E, and F. When corrugated paper is produced, multiple layers of corrugated paper need to be laminated to form a corrugated board.

[0003] For example, in a corrugated paper laminating device with the patent number CN202120022359.4, the following deficiencies exist in actual use:

[0004] The forming effect of the corrugated corrugated paper of the above device is not good. At the same time, when multiple layers of corrugated paper are laminated, glue needs to be coated on the upper end of the corrugated corrugated paper. The above patent coats it through a glue coating roll, which may cause extrusion and deformation of the corrugated corrugated paper during coating, affecting the lamination of the corrugated paper and resulting in poor coating effect. Summary of the Invention

[0005] In order to improve the problem of poor glue coating effect on the surface of corrugated corrugated paper, this application provides a corrugated board laminating device.

[0006] A corrugated board laminating device provided by this application adopts the following technical solutions:

[0007] A corrugated board laminating device includes compounding rollers symmetrically and fixedly arranged at one end of the installation frame up and down. On the upper and lower sides at one end of the installation frame away from the compounding rollers, a forming mechanism one and a forming mechanism two are respectively arranged, and the structural dimensions of the forming mechanism one and the forming mechanism two are the same;

[0008] The forming mechanism one includes a corrugated roll rotatably arranged in the middle of the bracket. A number of teeth are evenly arranged around the surface of the corrugated roll. A discharge pipe communicating with the inner cavity of the corrugated roll for discharging glue is arranged between every two teeth. The teeth of the forming mechanism one mesh with the teeth of the forming mechanism two and can extrude the corrugated paper into a wave shape.

[0009] By adopting the above technical solutions, the setting of the discharge pipe can discharge the glue inside the corrugated roll, and then coat the glue on the wave crests of the formed corrugated corrugated paper, which is very convenient and effective, saves the space of the device, and makes the structural setting more reasonable.

[0010] Preferably, the bracket of the forming mechanism one is fixed to the inner wall of the installation frame, and a slider is fixedly arranged on one side of the inner wall of the installation frame for the bracket of the forming mechanism two.

[0011] By adopting the above technical solution, the slider is set as a rectangle, which can limit the movement of the bracket and make its movement more stable.

[0012] Preferably, longitudinal grooves for the slider to slide are formed at positions corresponding to the slider on the outer surface of the installation frame. A bidirectional screw is movably inserted through both ends inside the longitudinal groove, and the threaded part of the bidirectional screw is threadedly arranged with the middle part of the slider.

[0013] By adopting the above technical solution, the setting of the bidirectional screw can drive the slider to longitudinally move in the longitudinal groove, thereby changing the height of the bracket of the second forming mechanism, and can be adjusted according to corrugated paper of different thicknesses to increase the practicability of the device.

[0014] Preferably, a plurality of guide rollers are rotatably arranged at one end of the bracket away from the corrugated roller.

[0015] By adopting the above technical solution, the guide rollers can reduce the friction between the surface corrugated paper and the bracket, and at the same time can make the device more compact in volume and make the structural design more reasonable.

[0016] Preferably, a conveying pipe communicating with the inner cavity of the corrugated roller is fixedly penetrated through one end of the corrugated roller away from the slider. One end of the conveying pipe movably penetrates through the bracket, and a rotating shaft movably inserted into the bracket is fixed at one end of the corrugated roller away from the conveying pipe.

[0017] By adopting the above technical solution, the setting of the conveying pipe can play a role in support and conveying glue. At the same time, the surface of the conveying pipe is set as a smooth surface, which can reduce the friction with the bracket and reduce wear.

[0018] Preferably, a first gear is sleeved and fixed on one side of the conveying pipe close to the bracket, and the end face of the first gear abuts against the end face of the bracket.

[0019] By adopting the above technical solution, the abutment of the end face of the first gear against the end face of the bracket can achieve the effect of limiting.

[0020] Preferably, a motor is embedded on one side of the bracket of the first forming mechanism. The output shaft of the motor is fixed with a second gear meshing with the first gear of the first forming mechanism, and the upper part of the second gear is meshed with the first gear of the second forming mechanism through a chain.

[0021] By adopting the above technical solution, the chain provided can make the first gear of the first forming mechanism and the first gear of the second forming mechanism rotate synchronously, realizing the extrusion effect on the corrugated paper.

[0022] Preferably, a guide plate in an "eight" shape is fixedly arranged in the middle of the inner cavity of the installation frame, and the merged end of the guide plate corresponds to the gap between the composite rollers.

[0023] By adopting the above technical solution, the guide plate can limit the two-sided corrugated paper, facilitating the lamination of the corrugated paper and enhancing the lamination effect.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The glue is transported to the inner cavity of the corrugated roller through the conveying pipe and then discharged from the discharge pipe to bond at the wave crests of the corrugated paper. This enables the glue to be coated at the initial stage of the formation of the corrugated paper, without affecting the structure of the corrugated paper. At the same time, it can make the glue coating more comprehensive and increase the structural strength of the laminated corrugated paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is a further detailed description of the present application in conjunction with the attached Figures 1-5 to the present application.

[0037] The embodiment of the present application discloses a corrugated board laminating device.

[0038] Embodiment 1

[0039] Refer toFigure 1 , a corrugated cardboard composite device, including a composite roller 2 symmetrically and fixedly arranged at one end of the inner cavity of the installation frame 1 up and down. The composite roller 2 is a prior art and the structure in the above-mentioned comparative document can be adopted. Since it is not the main technology, it will not be described in detail. On the upper side of the inner part of the installation frame 1 away from the composite roller 2, a forming mechanism 4 is arranged. On the lower side of the inner part of the installation frame 1 away from the composite roller 2, a forming mechanism 7 is arranged. The structural dimensions of the forming mechanism 4 and the forming mechanism 7 are the same. One end of the bracket 41 away from the corrugated roller 44 is provided with a rectangular groove. A number of guide rollers 46 are rotatably arranged in the groove through a connecting shaft. The guide rollers 46 are set as cylinders and the vertices protrude from the surface of the bracket 41. A guiding plate 3 in a shape of "eight" is fixedly arranged between the composite roller 2 and the forming mechanism 4 in the inner cavity of the installation frame 1. The merging end of the guiding plate 3 corresponds to the gap with the composite roller 2. The open end of the guiding plate 3 is located on one side of the guide rollers 46.

[0040] Through the above settings, the surface corrugated paper can drive the guide rollers 46 to rotate when it fits on the surfaces of the two guide rollers 46. And the surface corrugated paper passes through the middle parts of the opposite ends of the two guiding plates 3 to achieve the merging effect and at the same time passes through the middle gap of the composite roller 2. This setting can composite the two surface corrugated papers and the corrugated cardboard. It should be noted that the guiding plate 3 plays a role of limiting. At the same time, one end of the guiding plate 3 has an extended horizontal end, which can make the corrugated paper to be composite fit together and play a role of leveling.

[0041] Refer to Figure 1 、 2 、4, 5, the forming mechanism 4 includes a corrugated roller 44 rotatably arranged in the middle of the bracket 41. One end of the corrugated roller 44 away from the slider 10 is fixedly penetrated with a conveying pipe 43. The conveying pipe 43 is communicated with the inner cavity of the corrugated roller 44. And the conveying pipe 43 is preferably a steel pipe, which can play a supporting role. One end of the conveying pipe 43 located outside penetrates through one end of the bracket 41 movably. One end of the corrugated roller 44 away from the conveying pipe 43 is fixed with a rotating shaft 12. One end of the rotating shaft 12 is movably inserted into the bracket 41. A number of teeth 45 are evenly fixed around the surface of the corrugated roller 44 in an equidistant manner. A discharge pipe 47 for discharging glue is arranged between every two teeth 45. The discharge pipe 47 is communicated with the inner cavity of the corrugated roller 44. The discharge pipe 47 is set as a long strip to evenly apply glue to the convex parts of the corrugated cardboard. The teeth 45 of the forming mechanism 4 are meshed with the teeth 45 of the forming mechanism 7 and there is a gap. This gap squeezes the corrugated paper into a wave shape. The difference from the meshing mode of two gears is that the distance between two teeth 45 of the forming mechanism 4 is greater than the width of a single tooth 45 of the forming mechanism 7 and there is a gap for accommodating the corrugated paper.

[0042] With the above settings, the corrugated paper passes through between the teeth 45 of the forming mechanism 1 and the teeth 45 of the forming mechanism 2. Through the extrusion of the teeth 45 of the forming mechanism 1 and the teeth 45 of the forming mechanism 2, corrugated paper is formed. Subsequently, the conveying pipe 43 is connected to the glue pumping mechanism outside, so that the glue inside the glue tank is transported to the inside of the conveying pipe 43 through the glue pump and flows into the inner cavity of the corrugated roller 44 to gather. Then, the glue is discharged through the discharge pipe 47 and adhered to the convex end of the corrugated paper. This setting can coat the glue at the beginning of the formation of the corrugated paper, so it will not affect the structure of the corrugated paper.

[0043] Refer to Figure 2 、 4 , a first gear 42 is fixedly sleeved on one side of the conveying pipe 43 located outside. The end face of the first gear 42 abuts against the end face of the bracket 41 and rotates. An installation groove is provided on the bracket 41 of the forming mechanism 1 on one side of the conveying pipe 43. The inside of the installation groove is fixed to the installation end of the motor 11 by screws. The motor 11 is preferably a reduction motor. A second gear 5 is fixed to the output shaft of the motor 11. The second gear 5 meshes with the first gear 42 of the forming mechanism 1. The upper part of the second gear 5 meshes with one end of the chain 8. The other end of the chain 8 meshes with the first gear 42 of the forming mechanism 2.

[0044] With the above settings, when the motor 11 is powered on, the output shaft of the motor 11 drives the second gear 5 to rotate. The second gear 5 can drive the first gear 42 of the forming mechanism 1 to rotate and drive the first gear 42 of the forming mechanism 2 to rotate through the chain 8 at the same time. Thus, the corrugated rollers 44 of the forming mechanism 1 and the corrugated rollers 44 of the forming mechanism 2 rotate synchronously, providing a driving force for the corrugated paper while extruding the corrugated paper.

[0045] Refer to Figure 3 , one end of the bracket 41 of the forming mechanism 1 away from the conveying pipe 43 is fixed to the inner wall of the installation frame 1 by bolts. One end of the bracket 41 of the forming mechanism 2 is welded and fixed to one end of the slider 10 on the inner wall of the installation frame 1. A longitudinal groove 9 is provided on the outer surface of the installation frame 1 corresponding to the slider 10. The slider 10 slides longitudinally inside the longitudinal groove 9. It should be noted that, under normal conditions, the slider 10 is in the middle and lower part of the longitudinal groove 9, leaving space for the slider 10 to move at the lower end and the upper end of the longitudinal groove 9. Thus, the distance between the corrugated rollers 44 of the forming mechanism 1 and the corrugated rollers 44 of the forming mechanism 2 can be changed and adjusted according to corrugated paper of different thicknesses. The upper end of the longitudinal groove 9 is movably inserted through the smooth surface of the upper end of the double-threaded screw 6, and the lower end of the longitudinal groove 9 is movably inserted through the smooth surface of the lower end of the double-threaded screw 6. Both ends of the double-threaded screw 6 are provided with smooth surfaces. An internal threaded hole is provided in the middle of the slider 10. The threaded part of the double-threaded screw 6 is threadedly connected to the internal threaded hole of the slider 10.

[0046] With the above settings, the user can rotate the bidirectional screw 6 through the tool to drive the slider 10 to move longitudinally in the longitudinal groove 9. The slider 10 can drive the bracket 41 of the second forming mechanism 7 to move longitudinally, and the bracket 41 of the second forming mechanism 7 can drive the corrugated roller 44 of the second forming mechanism 7 to move longitudinally, thereby changing the gap between the corrugated roller 44 of the second forming mechanism 7 and the corrugated roller 44 of the first forming mechanism 4. It can be adjusted according to corrugated paper of different thicknesses to increase the usage range of the equipment and the practicability of the device.

[0047] This device also includes a corrugated paper traction device, etc. Other devices not described are set as existing devices to cooperate with this device. At the same time, this device is also provided with devices such as switches, wires, and controllers, which will not be elaborated in detail because they are not the main technologies.

[0048] The implementation principle of a corrugated board composite device according to an embodiment of this application is as follows: After installing two surface corrugated papers and the corrugated paper to be formed into a waveform, then, turn on the switch, and the controller controls the motor 11 to start. The motor 11 drives the second gear 5 to rotate. The second gear 5 can simultaneously drive the first gear 42 of the first forming mechanism 4 and the first gear 42 of the second forming mechanism 7 to rotate, thereby extruding the corrugated paper into a waveform. During the process of the corrugated paper forming into a waveform, the glue inside the corrugated roller 44 is discharged through the discharge pipe 47 to the surface of the wave crest of the corrugated paper. Under the action of the guide plate 3, the two surface corrugated papers clamp the corrugated paper, and then the two surface corrugated papers and the corrugated paper are bonded through the glue, and then are compounded through the compounding roller 2, thereby realizing the corrugated board.

[0049] With the above settings, this device coats the glue at the beginning of the formation of the corrugated paper, which will not affect the structure of the corrugated paper. At the same time, it can make the glue coating more comprehensive and increase the structural strength of the corrugated paper composite.

[0050] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
