Description

Technical Field

[0001] The present invention belongs to the technical field of corrugated paper manufacturing, and particularly relates to a composite component, device and method for a single-layer corrugated paper and a face paper. Background Art

[0002] Currently, in the world, the manufacturing of composites for duty is heated by a tin furnace or a large amount of electric energy (because in the prior art, high temperatures are used for the formed composite structures). During this process, a large amount of high-temperature wastewater and high-temperature waste gas are generated. Direct discharge is likely to pollute the environment, and there are certain safety hazards, with high energy consumption and high production costs.

[0003] In the existing production process, due to the influence of drying at high temperature and high humidity, the original physical indexes of the paper are greatly reduced, and it is easy to cause the paper to curl, which affects subsequent processing. Moreover, due to the uncertainty of the shrinkage of the paper itself during the heating process, there is a risk of reducing the finished product rate of fully automatic pre-printed paper products. Summary of the Invention

[0004] The purpose of the present invention is to: in order to overcome the disadvantages in the prior art, provide a composite component and device for a single-layer corrugated paper and a face paper. The present application adopts a rolling composite and static movement method, that is, it is composite in static movement. The gluing surface and the composite surface are stationary and move within two conveyor belts. Therefore, it is ensured that the composite surface does not slide. In this way, the amount of adhesive used can be reduced. Similarly, it can meet the requirement of rapid drying at normal temperature. Therefore, normal-temperature glue can be used, producing an effect different from high-temperature heating, and at the same time saving energy.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A composite component for a single-layer corrugated paper and a face paper, including a frame. A composite roller is rotatably connected to the frame. A first composite belt and a second composite belt are sequentially sleeved on the composite roller from the inside to the outside. The first composite belt sequentially passes through a first driving roller, a second driving roller and the composite roller. The second composite belt sequentially passes through a first turning roller, a second turning roller, a third turning roller, a fourth turning roller, a fifth turning roller and the composite roller.

[0007] Further preferably, the first composite belt, the second composite belt and the composite roller maintain relative synchronous transmission.

[0008] A composite device for a single-layer corrugated paper and a face paper, including the above composite component, a single-layer corrugated paper feeding unit and a face paper feeding unit;

[0009] At least one single-layer corrugated paper feeding unit is arranged on the frame. The single-layer corrugated paper feeding unit includes a feeding conveyor belt and a glue coating roller. The glue coating roller is fixedly arranged on the frame. The first conveyor belt is a structure for transmitting the single-layer corrugated paper;

[0010] At least one face paper feeding unit is arranged on the rack, and the face paper feeding unit includes a base paper rack, a first limiting roller, a second limiting roller, a third limiting roller, a fourth limiting roller and a fifth limiting roller;

[0011] At least one synchronization unit is connected to both the single-layer corrugated paper feeding unit and the face paper feeding unit. The synchronization unit includes a driving roller, a synchronous belt and a synchronous roller. The driving roller is connected to a driving unit. The driving roller is in transmission connection with the synchronous roller through the synchronous belt, and the synchronous roller is also in synchronous transmission connection with a first transmission roller;

[0012] An output conveyor belt is arranged at the upper end of the compounding roller.

[0013] A further preference of the present invention is that the driving unit includes a driving motor, a speed reducer and a universal joint coupling. A driving motor is arranged on the rack. The driving motor is in transmission connection with the speed reducer, the speed reducer is in transmission connection with the universal joint coupling, and the universal joint coupling is in transmission connection with the driving roller.

[0014] A further preference of the present invention is that a plurality of pressing rollers are arranged on the rack. The lower end surfaces of the pressing rollers are arranged on the same horizontal line. The pressing rollers are arranged above the output conveyor belt and are used to apply pressure to the corrugated paper after sizing.

[0015] A further preference of the present invention is that the compounding roller, the first compounding belt, the second compounding belt, the output conveyor belt and the input conveyor belt are kept in synchronous transmission.

[0016] A compounding method for single-layer corrugated paper and face paper, and at least three-layer corrugated paper board compounded by using the above compounding device.

[0017] A further preference of the present invention is that the corrugated paper board includes but is not limited to three-layer board, five-layer board or seven-layer board.

[0018] A further preference of the present invention is that the temperature for compounding the single-layer corrugated paper and the face paper is normal temperature.

[0019] A further preference of the present invention is that the transmission ratio of the output conveyor belt and the input conveyor belt is 100:97.

[0020] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are:

[0021] 1. The present invention adopts the method of adhesive pressing and static movement, that is, adhesive pressing and compounding during static movement, where the gluing surface and the compounding surface move within the relatively stationary first compounding belt and the second compounding belt. Therefore, it is ensured that there is no relative sliding on the compounding surface, which can reduce the amount of glue used. Also, it can maintain rapid bonding and rapid drying at normal temperature. Therefore, normal temperature glue can be used, producing an effect different from the high-temperature heating compounding of existing corrugated paper, and at the same time, saving energy.

[0022] 2. The quality of the corrugated paper product of the present invention is improved because the original physical indexes of the paper are maximally guaranteed during normal temperature compounding.

[0023] 3. The corrugated paper product of the present invention has greater adaptability because the color of the printing remains unchanged during normal temperature compounding. In the prior art, high temperature is prone to cause color change and high-temperature evaporation, which is likely to make the film blister, resulting in a poor finished product effect and a low finished product rate. Moreover, the present invention can smoothly compound products with film laminating or pre-printing on the film.

[0024] 4. The corrugated paper product of the present invention saves materials. Due to the lack of the characteristic of high-temperature shrinkage and no shrinkage in the paper, it can maintain the paper area of the original material.

[0025] 5. The present invention is provided with pressing rollers arranged side by side, and the pressing rollers are arranged on the upper side of the compounding surface of the corrugated paper. When the corrugated cardboard is discharged, the pressure of the pressing rollers directly acts on the compounding surface of the single-layer corrugated paper and the facing paper, and provides a certain pressure, making the compounding effect of the corrugated paper and the facing paper better.

[0026] 6. The transmission ratio of the discharge conveyor belt and the feed conveyor belt of the present invention is 100:97, which can weaken the elimination of the expansion coefficient of the corrugated paper after gluing, ensuring uniform and flat paper tension.

[0035] The following will Figure 1 and Figure 2 describe the present invention in detail.

[0036] Embodiment 1: A composite component of single-layer corrugated paper and facestock, comprising a frame 1, on which a composite roller 2 is rotatably connected. A first composite belt 3 and a second composite belt 4 are sequentially sleeved on the composite roller 2 from inside to outside. The first composite belt 3 sequentially passes through a first driving roller 5, a second driving roller 6 and the composite roller 2, and the second composite belt 4 sequentially passes through a first turning roller 7, a second turning roller 8, a third turning roller 9, a fourth turning roller 10, a fifth turning roller 11 and the composite roller 2.

[0037] A further preference of the present invention is that the first composite belt 3, the second composite belt 4 and the composite roller 2 maintain relative synchronous transmission.

[0038] Working principle: The present invention utilizes the fact that the gluing surface and the composite surface move within the relatively stationary first composite belt 3 and second composite belt 4, thus ensuring that there is no relative sliding on the composite surface, which can reduce the amount of glue used. Since both the first composite belt 3 and the second composite belt 4 are wound around the composite roller 2, the first composite belt 3 and the second composite belt 4 provide a huge pressure for the lamination of the facestock 17 and the single-layer corrugated paper 12. In cooperation with the adhesive, the single-layer corrugated paper 12 and the facestock 17 are quickly bonded and dried at room temperature.

[0039] Embodiment 2: A composite device for single-layer corrugated paper and facestock, comprising the aforementioned composite component, a single-layer corrugated paper feeding unit and a facestock feeding unit;

[0040] A single-layer corrugated paper feeding unit is arranged on the frame 1. The single-layer corrugated paper feeding unit includes a feeding conveyor belt 20 and a glue application roller 21. The glue application roller 21 is fixedly arranged on the frame 1. The first conveyor belt is a structure for transporting the single-layer corrugated paper 12;

[0041] A facial paper feeding unit is arranged on the frame 1. The facial paper feeding unit includes a base paper rack 13, a first limiting roller 14, a second limiting roller 15, a third limiting roller 16, a fourth limiting roller 18 and a fifth limiting roller 19;

[0042] A single-layer corrugated paper feeding unit and the facial paper feeding unit are both connected with a synchronization unit. The synchronization unit includes a driving roller 23, a synchronous belt 24 and a synchronous roller 22. The driving roller 23 is connected with a driving unit 25. The driving roller 23 is in transmission connection with the synchronous roller 22 through the synchronous belt 24. The synchronous roller 22 is also in synchronous transmission connection with a first transmission roller 5;

[0043] A discharge conveyor belt 27 is arranged above the compounding roller 2.

[0044] The driving unit 25 includes a driving motor, a speed reducer and a universal joint coupling. The driving motor is arranged on the frame 1. The driving motor is in transmission connection with the speed reducer. The speed reducer is in transmission connection with the universal joint coupling. The universal joint coupling is in transmission connection with the driving roller 23. A plurality of pressing rollers 26 are arranged on the frame 1. The lower end surfaces of the pressing rollers 26 are on the same horizontal line. The pressing rollers 26 are arranged above the discharge conveyor belt 27. The pressing rollers 26 are used to apply pressure to the corrugated paper after sizing.

[0045] The compounding roller 2, the first compounding belt 3, the second compounding belt 4, the discharge conveyor belt 27 and the feeding conveyor belt 20 are kept in synchronous transmission, so that the compounding surface and the sizing surface are kept in a relatively static state. Therefore, it is ensured that there is no relative sliding on the compounding surface, which can reduce the amount of glue used. Similarly, it can maintain fast bonding and fast drying at normal temperature.

[0046] Working principle: The present invention utilizes a single-layer corrugated paper 12 to be sequentially transmitted through a feeding conveyor belt 20. A glue applicator roller 21 provided at the lower end of the single-layer corrugated paper 12 is used to apply glue to the side where the single-layer corrugated paper 12 is laminated with the face paper 17. Under the action of a driving motor, a reducer, a universal joint coupling, a driving roller 23, a synchronous belt 24, a synchronous roller 22, and a first composite belt 3, since the inner side of the first composite belt 3 is in frictional contact with the second composite belt 4, the composite roller 2 is driven to rotate, and the composite roller 2, the first composite belt 3, the second composite belt 4, the discharging conveyor belt 27, and the feeding conveyor belt 20 are kept in synchronous transmission, so that the glue-applied surface and the composite surface move within the relatively stationary first composite belt 3 and second composite belt 4. Therefore, relative sliding between the composite surface and the glue-applied surface is prevented, which can reduce the amount of glue used. The first composite belt 3 and the second composite belt 4 provide a huge pressure for laminating the face paper 17 and the single-layer corrugated paper 12. In cooperation with the adhesive, the single-layer corrugated paper 12 and the face paper 17 can be quickly laminated and dried at room temperature. Moreover, multiple groups of pressing rollers 26 are provided on the upper side of the discharging conveyor belt. The length of the pressing rollers 26 can be set according to actual requirements. The pressing rollers 26 are arranged on the upper side of the corrugated paper composite surface. When the corrugated board is discharged, the pressure of the pressing rollers 26 directly acts on the composite surface of the single-layer corrugated paper 12 and the face paper 17, and provides a certain pressure, making the lamination effect of the corrugated paper and the face paper 17 better.

[0047] Embodiment 3: As Figure 2 shown, a composite device for a single-layer corrugated paper and a face paper includes the aforementioned composite assembly, two single-layer corrugated paper feeding units, and one face paper feeding unit;

[0048] Two single-layer corrugated paper feeding units are provided on a frame 1. The single-layer corrugated paper feeding unit includes a feeding conveyor belt 20 and a glue applicator roller 21. The glue applicator roller 21 is fixedly arranged on the frame 1. The first conveyor belt is a structure for transmitting the single-layer corrugated paper 12;

[0049] One face paper feeding unit is provided on the frame 1. The face paper feeding unit includes a base paper rack 13, a first limiting roller 14, a second limiting roller 15, a third limiting roller 16, a fourth limiting roller 18, and a fifth limiting roller 19;

[0050] Both the single-layer corrugated paper feeding unit and the face paper feeding unit are connected with a synchronous unit. The synchronous unit includes a driving roller 23, a synchronous belt 24, and a synchronous roller 22. The driving roller 23 is connected with a driving unit 25. The driving roller 23 is in transmission connection with the synchronous roller 22 through the synchronous belt 24. The synchronous roller 22 is also in synchronous transmission connection with a first transmission roller 5;

[0051] A discharging conveyor belt 27 is provided at the upper end of the composite roller 2.

[0052] The driving unit 25 includes a driving motor, a reducer and a universal joint coupling. The driving motor is arranged on the frame 1, the driving motor is transmission-connected to the reducer, the reducer is transmission-connected to the universal joint coupling, the universal joint coupling is transmission-connected to the active roller 23, a plurality of pressure rollers 26 are arranged on the frame 1, the lower end surfaces of the pressure rollers 26 are arranged on the same horizontal line, the pressure rollers 26 are arranged at the upper end of the discharge conveyor belt 27, and the pressure rollers 26 are used to provide pressure to the corrugated paper after gluing.

[0053] The composite roller 2, the first composite belt 3, the second composite belt 4, the discharge conveyor belt 27 and the feed conveyor belt 20 maintain synchronous transmission, so that the composite surface and the glue surface remain in a relatively static state, thereby ensuring that the composite surface does not slide relative to each other, which can reduce the amount of glue used and also maintain rapid bonding and rapid drying at room temperature.

[0054] Working principle: The present invention utilizes the single-layer corrugated paper 12 to be sequentially transmitted through the feeding conveyor belt 20, and utilizes the glue coating roller 21 provided at the lower end of the single-layer corrugated paper 12 to coat the glue on the side where the single-layer corrugated paper 12 and the face paper 17 are composited. Under the action of the driving motor, the reducer, the universal joint coupling, the active roller 23, the synchronous belt 24, the synchronous roller 22 and the first composite belt 3, the inner side of the first composite belt 3 is in frictional contact with the second composite belt 4, thereby driving the composite roller 2 to rotate, and maintaining the composite roller 2, the first composite belt 3, the second composite belt 4, the discharging conveyor belt 27 and the feeding conveyor belt 20 to maintain synchronous transmission, so that the glued surface and the composite surface are kept moving in the relatively stationary first composite belt 3 and the second composite belt 4 , thereby ensuring that the composite surface and the gluing surface do not slide relative to each other, and thus reducing the amount of glue used, so that the first composite belt 3 and the second composite belt 4 provide huge pressure on the composite of the facing paper 17 and the single-layer corrugated paper 12, and cooperate with the adhesive glue to ensure that the single-layer corrugated paper 12 and the face paper 17 are quickly bonded and dried at room temperature, and multiple groups of pressing rollers 26 are arranged on the upper side of the discharge conveyor belt, and the length of the pressing roller 26 can be set according to actual needs, and the pressing roller 26 is arranged on the upper side of the corrugated paper composite surface, so that when the corrugated board is discharged, the pressure of the pressing roller 26 directly acts on the composite surface of the single-layer corrugated paper 12 and the face paper 17, and provides a certain pressure, so that the composite effect of the corrugated paper and the face paper 17 is better.

[0055] Implementation Case 4: A method for compounding a single-layer corrugated paper and a face paper, using the aforementioned compounding device to compound at least three layers of corrugated paperboard.

[0056] Corrugated paperboard includes but is not limited to three-layer paperboard, five-layer paperboard or seven-layer paperboard. The present invention can be based on actual needs and only needs to increase or decrease a single single-layer corrugated paper feeding unit, so that multiple single-layer corrugated papers 12 are glued and superimposed on each other to form the three-layer corrugated paper, five-layer corrugated paper or seven-layer corrugated paper required by the user.

[0057] The temperature for the lamination of the single-layer corrugated paper 12 and the face paper 17 is normal temperature. Due to the pressure of the first lamination belt 3 and the second lamination belt 4, the lamination of the single-layer corrugated paper 12 and the face paper 17 can be achieved without high-temperature lamination. Similarly, rapid adhesion and rapid drying can be maintained at normal temperature. Therefore, normal-temperature glue can be used, resulting in an effect different from the high-temperature heating lamination of the existing corrugated paper. At the same time, energy is saved.

[0058] Embodiment 5: The transmission ratio of the discharge conveyor belt and the feed conveyor belt is 100:97, which can weaken the elimination of the expansion coefficient of the corrugated paper after sizing, ensure uniform and flat paper tension, and can also adjust different transmission ratios according to actual needs.

[0059] The fixed connection, fixed installation or fixed setting methods include existing common technologies, such as bolt fixation, welding, riveting, etc., all of which are for the purpose of fixation and do not affect the overall effect of the device.
