Description

Technical Field

[0001] This utility model relates to a double-sided machine, and more particularly to a double-sided machine for simultaneously bonding and pressing corrugated paper. Background Technology

[0002] In the corrugated paper production industry, double-facers include a lower conveyor mechanism and an upper pressure roller mechanism located above the lower conveyor mechanism. During operation, corrugated paper with glue on its teeth is fed into the lower conveyor mechanism, while the face paper is fed into the upper pressure roller mechanism. This causes the teeth and face paper to be continuously bonded together under the pressure of the lower conveyor mechanism and the upper pressure roller mechanism, respectively, thus forming a three-layer corrugated paper structure. In this structure, the upper pressure roller mechanism consists of a row of horizontally arranged pressure rollers. During operation, the lower conveyor mechanism drives the corrugated paper with glue on its teeth forward, while the corrugated paper with glue on its teeth, through friction, drives the face paper forward, causing the pressure rollers to rotate accordingly, achieving continuous bonding between the corrugated paper with glue on its teeth and the face paper. However, this type of double-facer has a problem where the corrugated paper with glue on its teeth moves the face paper through friction. This can cause the teeth to be stretched horizontally, resulting in misalignment and leading to misalignment between the corrugated paper with glue on its teeth and the face paper. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems by providing a double-sided machine capable of simultaneously bonding and pressing corrugated paper and face paper with adhesive on the tooth tips. This double-sided machine can move and press the corrugated paper and face paper with adhesive on the tooth tips together synchronously, without causing misalignment, ensuring accurate alignment and improving the quality and production stability of three-layer corrugated paper.

[0004] The objective of this utility model can be achieved by the following technical solutions: A double-sided machine with simultaneous gluing and pressing of corrugated paper, including The lower conveyor mechanism is used to drive the corrugated paper with glue stuck to the tooth tips to move forward; The pressing mechanism is used to drive the face paper forward and press the face paper together with the tooth tips which are glued together; The upper pressing mechanism is equipped with a power device, which drives the upper pressing mechanism and the lower conveying mechanism to rotate synchronously, so that the corrugated paper with glue on the tooth tips located between the lower conveying mechanism and the upper pressing mechanism moves synchronously and is pressed together with the face paper.

[0005] As a preferred embodiment, the pressing mechanism includes an upper driving roller, an upper driven roller, a pressing belt, and a power device. The pressing belt is wound around the upper driving roller and the upper driven roller. The power output end of the power device is connected to the upper driving roller to drive the pressing belt to move. The pressing belt drives the face paper to move and presses the face paper against the corrugated paper with glue on the tooth tips.

[0006] As a preferred embodiment, a pressure roller is provided between the upper driving roller and the upper driven roller to press the pressure belt onto the face paper. The pressure roller applies pressure to the face paper in the direction of the corrugated paper with glue on the tooth tips through the pressure belt.

[0007] As a preferred embodiment, a pressure plate is provided between the upper driving roller and the upper driven roller to press the pressure belt against the face paper. The pressure plate applies pressure to the face paper in the direction of the corrugated paper with glue on the tooth tips through the pressure belt.

[0008] As a preferred embodiment, the pressing mechanism includes an active pressure roller, a transmission mechanism, and a power unit. The power unit drives the active pressure roller to rotate synchronously through the transmission mechanism. The active pressure roller applies pressure to the face paper in the direction of the corrugated paper with glue on the tooth tips.

[0009] As a preferred embodiment, the transmission mechanism includes a main synchronous pulley, a driven synchronous pulley, and a synchronous belt. The driven synchronous pulley is fixedly installed on one end of the driving pressure roller. The synchronous belt is wound around the main synchronous pulley and the driven synchronous pulley. The power output end of the power unit is connected to the main synchronous pulley.

[0010] As a preferred embodiment, the lower conveying mechanism includes a lower driving roller, a lower driven roller, a conveyor belt, and a second power device. The conveyor belt is wound around the lower driving roller and the lower driven roller. The power output end of the second power device is connected to the lower driving roller to drive the conveyor belt to move. The conveyor belt drives the corrugated paper with glue stuck to its tooth tips to move.

[0011] As a preferred embodiment, a heating device for heating the conveyor belt is provided between the lower driving roller and the lower driven roller.

[0012] As a preferred embodiment, the heating device is a heater; the power device is an electric motor.

[0013] As a preferred embodiment, the heating device includes a support plate for supporting the conveyor belt and a heater disposed on the support plate.

[0014] Implementing this utility model has the following beneficial effects: 1. During operation, the lower conveyor and upper pressing mechanisms rotate synchronously, causing the corrugated paper with glue on the tooth tips and the face paper to move forward simultaneously. Simultaneously, the upper pressing mechanism applies vertical downward pressure to the face paper, pressing it against the tooth tips of the corrugated paper, continuously bonding the face paper to the tooth tips to form a continuous three-layer corrugated board. Because the lower conveyor and upper pressing mechanisms drive the corrugated paper with glue on the tooth tips and the face paper to move synchronously, the corrugated paper with glue on the tooth tips does not need to drive the face paper forward through friction, preventing horizontal stretching deformation between the tooth tips and the face paper. This ensures accurate alignment between the tooth tips and the face paper, improving product quality and stability.

[0015] 2. This utility model can make the pressure distribution of the pressure belt on the paper more uniform by using a pressure roller, and make the pressure between the paper and the tooth tip more uniform, thereby improving the stability and reliability of their adhesion.

[0016] 3. This structure directly drives the face paper forward via an active pressure roller. The power unit drives multiple active pressure rollers to rotate synchronously through a transmission mechanism. This means the active pressure rollers not only drive the face paper forward but also apply pressure to the face paper towards the corrugated paper with adhesive on the tooth tips, causing the face paper and the corrugated paper with adhesive to continuously and synchronously adhere together. This structure only requires a single-specification and-sized active pressure roller to achieve the function and purpose of synchronous adhesion and pressing, eliminating the need for a pressure belt, upper active roller, and upper driven roller, simplifying the structure and reducing manufacturing costs.

[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. Example

[0022] Reference Figure 1 and Figure 2This embodiment relates to a double-sided machine with synchronously pressing corrugated paper, including a lower conveying mechanism 100 for driving the corrugated paper 2 with glue on the tooth tips 1 to move forward, and an upper pressing mechanism 200 for driving the face paper 3 to move forward. The upper pressing mechanism 200 presses the face paper 3 and the tooth tips 1 together with glue. The upper pressing mechanism 200 is provided with a power device (not shown in the figure). The power device drives the upper pressing mechanism 200 and the lower conveying mechanism 100 to rotate synchronously, so that the corrugated paper 2 with glue on the tooth tips 1 located between the lower conveying mechanism 100 and the upper pressing mechanism 200 moves synchronously and is pressed together with the face paper 3.

[0023] like Figure 1 and Figure 2 As shown, during operation, the lower conveying mechanism 100 and the upper pressing mechanism 200 rotate synchronously, causing the corrugated paper 2 with glue on the tooth tips 1 and the face paper 3 to move forward synchronously. Simultaneously, the upper pressing mechanism 200 applies vertical downward pressure to the face paper 3, pressing it against the tooth tips 1 of the corrugated paper 2, causing the face paper 3 to continuously adhere to the tooth tips 1, thus forming a continuous three-layer corrugated cardboard 300. Because the lower conveying mechanism 100 and the upper pressing mechanism 200 drive the corrugated paper 2 with glue on the tooth tips 1 and the face paper 3 to move synchronously, the corrugated paper 2 with glue on the tooth tips 1 does not need to drive the face paper 3 forward through friction, preventing horizontal stretching deformation between the tooth tips 1 and the face paper 3. This ensures accurate alignment between the tooth tips 1 and the face paper 3, improving product quality and stability.

[0024] The pressing mechanism 200 includes an upper driving roller 4, an upper driven roller 5, a pressure belt 6, and a power unit. The pressure belt 6 is wound around the upper driving roller 4 and the upper driven roller 5. The power output end of the power unit is connected to the upper driving roller 4 to drive the pressure belt 6. The pressure belt 6 drives the face paper 3 to move, and the pressure belt 6 presses the face paper 3 against the corrugated paper 2 with glue on the tooth tips 1. The power unit drives the pressure belt 6 to move through the upper driving roller 4; the pressure belt 6 drives the face paper 3 to move forward through friction. During operation, the pressure belt 6 drives the face paper 3 to move forward, and at the same time, the pressure belt 6 applies pressure to the face paper 3 towards the corrugated paper 2 with glue on the tooth tips 1, so that the face paper 3 and the corrugated paper 2 with glue on the tooth tips 1 are continuously bonded together. The power unit is an electric motor. By controlling the speed of the motor, the movement speed of the pressure belt 6 is made equal to the speed of the corrugated paper 2 with glue on the driving tooth tip 1 of the lower conveyor mechanism 100, thereby realizing the synchronous movement and pressing of the corrugated paper 2 with glue on the tooth tip 1 and the face paper 3.

[0025] A pressure roller 7 is provided between the upper driving roller 4 and the upper driven roller 5 to press the pressure belt 6 against the face paper 3. The pressure roller 7 applies pressure to the face paper 3 via the pressure belt 6 in the direction of the corrugated paper 2 with adhesive on the tooth tips 1. The pressure roller 7 ensures a more uniform pressure distribution between the pressure belt 6 and the face paper 3, resulting in more even pressure between the face paper 3 and the tooth tips 1, thereby improving the stability and reliability of their adhesion. Figure 1As shown, multiple pressure rollers 7 are provided and evenly distributed on the lower edge of the pressure belt 6. The pressure rollers 7 can be movable or fixed. A guide roller 8 is provided on the pressure belt 6 at the entrance of the face paper 3. The guide roller 8 mainly serves to tension the pressure belt 6.

[0026] The lower conveying mechanism 100 includes a lower driving roller 9, a lower driven roller 10, a conveyor belt 11, and a second power unit. The conveyor belt 11 is wound around the lower driving roller 9 and the lower driven roller 10. The power output end of the second power unit is connected to the lower driving roller 9 to drive the conveyor belt 11. The conveyor belt 11 drives the corrugated paper 2 with glue on its tooth tips 1 to move. During operation, the second power unit drives the lower driving roller 9, which in turn drives the conveyor belt 11. The second power unit is a motor. By controlling the speed of the motor, the conveyor belt 11 and the pressure belt 6 move at the same speed, so that the corrugated paper 2 with glue on its tooth tips 1 and the face paper 3 move forward synchronously, preventing horizontal stretching deformation between them and ensuring the accurate alignment of the face paper 3 and the tooth tips 1.

[0027] To increase the bonding speed between the corrugated paper 2 with glue on the tooth tips 1 and the face paper 3, a heating device 12 for heating the conveyor belt 11 is provided between the lower drive roller 9 and the lower driven roller 10. Heating the conveyor belt 11 by the heating device 12 raises the temperature of the space between the corrugated paper 2 with glue on the tooth tips 1 and the face paper 3, thereby increasing the bonding speed. The heating device 12 is a heater; or the heating device 12 includes a support plate for supporting the conveyor belt 11 and a heater disposed on the support plate. The heater heats the support plate, causing the support plate to transfer heat to the conveyor belt 11. Part of the heat is transferred to heat the corrugated paper 2 with glue on the tooth tips 1, and another part directly heats the space between the corrugated paper 2 with glue on the tooth tips 1 and the face paper 3, causing the space to rise. Example

[0028] This embodiment is based on Embodiment 1, and is an improvement on the pressure roller 7, such as... Figure 2 As shown, a pressure plate 13 is provided between the upper driving roller 4 and the upper driven roller 5 to press the pressure belt 6 against the face paper 3. The pressure plate 13 applies pressure to the face paper 3 via the pressure belt 6 in the direction of the corrugated paper 2 with adhesive on the tooth tips 1. The pressure plate 13 makes the pressure distribution of the pressure belt 6 on the face paper 3 more uniform, making the pressure between the face paper 3 and the tooth tips 1 more uniform, thereby improving the stability and reliability of their adhesion. Figure 2 As shown, multiple pressure plates 13 are provided and are evenly distributed on the lower edge of the pressure belt 6. The pressure plates 13 are fixedly mounted on the double-sided machine. Example

[0029] This embodiment is an improvement on the pressing mechanism 200 based on Embodiment 1, such as... Figure 3 As shown, the upper pressing mechanism 200 includes an active pressure roller 14, a transmission mechanism, and a power unit. The power unit drives the active pressure roller 14 to rotate synchronously through the transmission mechanism. The active pressure roller 14 applies pressure to the face paper 3 in the direction of the corrugated paper 2 with glue on the tooth tips 1. In this structure, the face paper 3 is directly driven forward by the active pressure roller 14. The power unit drives multiple active pressure rollers 14 to rotate synchronously through the transmission mechanism. That is, the active pressure roller 14 not only drives the face paper 3 to move forward, but also applies pressure to the face paper 3 in the direction of the corrugated paper 2 with glue on the tooth tips 1, so that the face paper 3 and the corrugated paper 2 with glue on the tooth tips 1 are continuously and synchronously bonded together. This structure only requires an active pressure roller 14 of a single specification and size to achieve the function and purpose of synchronous bonding and pressing, eliminating the need for a pressure belt 6, an upper active roller 4, and an upper driven roller 5, simplifying the structure and reducing manufacturing costs.

[0030] The transmission mechanism includes a main synchronous pulley, a driven synchronous pulley, and a synchronous belt. The driven synchronous pulley is fixedly mounted on one end of the driving pressure roller 14. The synchronous belt is wound around the main and driven synchronous pulleys. The power output end of the power unit is connected to the main synchronous pulley. When the power unit drives the main synchronous pulley to rotate, the main synchronous pulley drives the synchronous belt and the driven synchronous pulley to move synchronously. The synchronous belt drives multiple driven synchronous pulleys to rotate, ensuring that all driving pressure rollers rotate at the same speed, i.e., all driving pressure rollers 14 are in a synchronous rotational working state. The rotational speed of the driving pressure rollers 14 is controlled by controlling the rotational speed of the power unit, ensuring that the rotational speed of the driving pressure rollers 14 is equal to the running speed of the conveyor belt 11.

[0031] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
