This invention facilitates rapid rewetting, transfer, and humidification, is convenient to use, easy to operate, highly efficient, and saves time.

[0004] In the existing technology, the positions of the humidifying roller, the power roller, and the transfer roller are relatively fixed. Therefore, the contact area between the paper and the power roller and the transfer roller is also relatively fixed. This makes it impossible to adjust when dealing with the different processing requirements of different papers for the amount of water adhering, resulting in unsatisfactory humidification effect. Utility Model Content

[0005] The present invention aims to provide a three-roller humidification mechanism that can adjust the humidification contact area during paper humidification treatment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a three-roller humidification mechanism, including a humidification roller, a power roller and a transfer roller, and a housing, wherein the humidification roller, the power roller and the transfer roller are all disposed inside the housing, and the housing is provided with a moving mechanism connected to the transfer roller, the moving mechanism being divided into a moving block disposed on the housing and connected to the transfer roller, and a screw disposed on the moving block.

[0007] The housing is provided with a mounting frame, the movable block is disposed within the mounting frame, and the screw is disposed on the side of the movable block.

[0008] The mounting frame is U-shaped, and a sealing plate is provided at the opening of the mounting frame. The screw passes through the sealing plate and is connected to the moving block.

[0009] The inner side of the mounting frame is provided with a guide rail that cooperates with the moving block.

[0010] The moving block is threadedly connected to the screw, and the moving block is hinged to the transfer roller.

[0011] The housing is equipped with a first motor and a second motor. The first motor is connected to the humidifying roller, and the second motor is connected to the power roller.

[0012] The humidifying roller is in contact with the power roller, the power roller is located between the humidifying roller and the transfer roller, and the transfer roller is in close contact with the power roller.

[0013] The humidifying roller, the power roller, and the transfer roller are arranged vertically, while the screw is arranged horizontally.

[0014] The screw is provided in multiple parts.

[0015] The technical effect of this utility model is as follows: by adjusting the position of the transfer roller through the moving mechanism, the distance between the transfer roller and the shaft of the power roller can be adjusted. Since the transfer roller is a rubber roller, when the transfer roller and the power roller are far apart, the compression of the transfer roller is small and the contact area between the transfer roller and the power roller is small. Conversely, the contact area increases. In this way, the area of ​​paper adhering to the power roller can be adjusted, thereby adjusting the amount of water on the paper. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0022] Please see Figure 1-3 A three-roller humidification mechanism includes a humidifying roller 1, a power roller 2, and a transfer roller 3, and a housing 4. The humidifying roller 1, power roller 2, and transfer roller 3 are all disposed within the housing 4. The housing 4 is provided with a moving mechanism connected to the transfer roller 3. The moving mechanism consists of a moving block 5 disposed on the housing 4 and connected to the transfer roller 3, and a screw 6 disposed on the moving block 5. The position of the transfer roller 3 is adjusted by the moving mechanism to adjust the distance between the axis of the transfer roller 3 and the power roller 2. Since the transfer roller 3 is a rubber roller, when the transfer roller 3 is far away from the power roller 2, the compression of the transfer roller 3 is small, and the contact area between the transfer roller 3 and the power roller 2 is small. Conversely, the contact area increases as the distance increases. This can adjust the area of ​​paper adhering to the power roller 2, thereby adjusting the amount of water on the paper. The position of the transfer roller 3 is adjusted by moving the moving block 5 through the screw 6.

[0023] The housing 4 is provided with a mounting frame 7, the movable block 5 is set inside the mounting frame 7, and the screw 6 is set on the side of the movable block 5; the movement of the movable block 5 is restricted, thereby protecting the position of the transfer roller 3.

[0024] The mounting frame 7 is U-shaped, and a sealing plate 8 is provided at the opening of the mounting frame 7. The screw 6 passes through the sealing plate 8 and is connected to the movable block 5. The screw 6 drives the movable block 5 to move, and the sealing plate 8 can prevent the movable block 5 from detaching from the mounting frame 7.

[0025] The inner side of the mounting frame 7 is provided with a guide rail 9 that cooperates with the movable block 5; this facilitates the movement of the movable block 5 within the mounting frame 7.

[0026] The movable block 5 is threadedly connected to the screw 6, and the movable block 5 is hinged to the transfer roller 3: the movable block 5 can be moved by rotating the screw 6. The screw 6 is hinged to the sealing plate 8 to prevent the screw 6 from falling off.

[0027] The housing 4 is equipped with a first motor 10 and a second motor 11. The first motor 10 is connected to the humidifying roller 1, and the second motor 11 is connected to the power roller 2. Power is supplied to the humidifying roller 1 and the power roller 2 through the first motor 10 and the second motor 11.

[0028] The humidifying roller 1 is in contact with the power roller 2, and the power roller 2 is located between the humidifying roller 1 and the transfer roller 3; the humidifying roller 1 transfers the adhering water to the power roller 2, thereby adhering it to the paper.

[0029] The humidifying roller 1, the power roller 2, and the transfer roller 3 are arranged vertically, while the screw 6 is arranged horizontally, allowing the screw 6 to move along a tangential direction, making it easier to adjust the position of the transfer roller 3. The transfer roller 3 is in close contact with the power roller 2, ensuring that the transfer roller 3 is always in contact with the power roller 2.

[0030] Multiple screws 6 are provided; this makes the position of the moving block 5 more secure after it is moved, reducing the occurrence of errors caused by shaking.

[0031] Working principle: The paper is located between the power roller 2 and the transfer roller 3. The water adhering to the surface of the humidifying roller 1 is squeezed and moved to the power roller 2. As the power roller 2 moves, it is transported and adhered to the surface of the paper. The position of the transfer roller 3 is adjusted by the moving mechanism. Since the transfer roller 3 is a rubber roller, it is attached to the power roller 2. As the transfer roller 3 moves, the contact area between the transfer roller 3 and the power roller 2 will change, thereby adjusting the area of ​​the paper adhering to the power roller 2, and thus adjusting the amount of water absorbed by the paper.

[0032] The technical effect of this utility model is as follows: by adjusting the position of the transfer roller 3 through the moving mechanism, the distance between the transfer roller 3 and the axis of the power roller 2 can be adjusted. Since the transfer roller 3 is a rubber roller, when the transfer roller 3 and the power roller 2 are far apart, the compression of the transfer roller 3 is small and the contact area between the transfer roller 3 and the power roller 2 is small. Conversely, the contact area increases. In this way, the area of ​​paper attached to the power roller 2 can be adjusted, thereby adjusting the amount of water on the paper.

[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
