[0002] A coating machine is mainly used for surface coating processes of films, paper, etc. It applies materials such as adhesives and coatings to the surface of the material. During coating, humidification treatment is required according to the characteristics of the material. The most common humidification treatment mechanism is the three-roll humidification mechanism.

[0003] A patent application with patent number 201510729383.0 and publication date of January 4, 2017, discloses a three-roller humidification and transfer device for paper rewetting, which relates to the field of mechanical equipment technology. A rewetting roller motor is mounted on the shaft of the rewetting roller, a transfer roller is located at the lower right end of the rewetting roller, a transfer roller motor is mounted on the shaft of the transfer roller, an installation sleeve is installed inside the transfer roller, a spring is installed at the bottom of the installation sleeve, a transfer ball is installed at the upper end of the spring, a humidification roller is located on the upper right side of the transfer roller, a humidification roller motor is mounted on the shaft of the humidification roller, and a humidification head is installed inside the humidification roller. 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, different materials have different requirements for the amount of water required during coating. Adjusting the amount of water according to different materials can improve the quality of material forming. However, current coating machines do not have a good way to adjust the amount of water. Therefore, when different materials are humidified on the same coating machine, the quality results are inconsistent. Utility Model Content

[0005] The present invention aims to provide a three-roller humidification mechanism that can adjust the amount of water applied to different materials.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a three-roller humidification mechanism, including a housing, a transfer roller, a power roller and a humidification roller are provided inside the housing, and three independent motors are provided on the housing. The motors are divided into a first motor connected to the transfer roller, a second motor connected to the power roller and a third motor connected to the humidification roller.

[0007] The speeds of the first motor and the second motor are independent of each other.

[0008] The transfer roller is a rubber roller.

[0009] The transfer roller and the power roller are in close contact with each other, and a cloth is provided between the transfer roller and the power roller.

[0010] The humidifying roller is in contact with the power roller.

[0011] The lower half of the humidifying roller is submerged in water.

[0012] The transfer roller, power roller, and humidifying roller are arranged from top to bottom.

[0013] The technical advantages of this invention are as follows: By using three independent motors to control the transfer roller, the power roller, and the humidifying roller respectively, the rotation speeds of the three rollers are made independent of each other. By controlling the rotation speeds of the power roller and the transfer roller, a speed difference is created between them. When the rotation speed of the power roller is greater than that of the transfer roller, the power roller can carry more water to adhere to the fabric, while when the rotation speed of the power roller is lower than that of the transfer roller, less water adheres to the fabric. Thus, the amount of water adhering can be adjusted according to the different requirements of the material. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1 A three-roller humidification mechanism includes a housing 1, within which a transfer roller 2, a power roller 3, and a humidification roller 4 are disposed. The housing 1 is equipped with three independent motors: a first motor 5 connected to the transfer roller 2, a second motor 6 connected to the power roller 3, and a third motor 7 connected to the humidification roller 4. These three independent motors control the transfer roller 2, power roller 3, and humidification roller 4 respectively, ensuring that the rotational speeds of the three rollers are independent. By controlling the rotational speeds of the power roller 3 and the transfer roller 2, a speed difference is created between them. When the rotational speed of the power roller 3 is greater than that of the transfer roller 2, the power roller 3 can carry more water and adhere it to the fabric; conversely, when the rotational speed of the power roller 3 is lower than that of the transfer roller 2, less water adheres to the fabric. This allows for adjustment of the water application amount according to the different requirements of the material.

[0019] The rotational speeds of the first motor 5 and the second motor 6 are independent of each other; thus, the rotational speed between the transfer roller 2 and the power roller 3 can be controlled to adjust the amount of water applied.

[0020] The transfer roller 2 is a rubber roller, which makes the adhesive properties of the transfer roller 2 stronger than those of the power roller 3. Thus, the movement of the fabric is controlled by the transfer roller 2, and the power roller 3 has less impact on the movement of the fabric.

[0021] The transfer roller 2 and the power roller 3 are in close contact with each other, and a cloth is placed between the transfer roller 2 and the power roller 3; the transfer roller 2 drives the cloth to move, and the power roller 3 sticks water onto the cloth.

[0022] The humidifying roller 4 is in contact with the power roller 3; water is adhering to the power roller 3 through the humidifying roller 4, thereby transferring and adhering it to the fabric.

[0023] The lower half of the humidifying roller 4 is immersed in water; water adheres to the humidifying roller 4.

[0024] The transfer roller 2, the power roller 3, and the humidifying roller 4 are arranged from top to bottom; the humidifying roller 4 transfers water from the bottom of the machine to the power roller 3, and then transfers it to the fabric.

[0025] The technical effect of this utility model is as follows: By using three independent motors to control the transfer roller 2, the power roller 3, and the humidifying roller 4 respectively, the rotation speed of the three rollers is made independent of each other. By controlling the rotation speed of the power roller 3 and the transfer roller 2, a speed difference is generated between the power roller 3 and the transfer roller 2. When the rotation speed of the power roller 3 is greater than that of the transfer roller 2, the power roller 3 can carry more water to adhere to the fabric, while when the rotation speed of the power roller 3 is lower than that of the transfer roller 2, less water adheres to the fabric, thereby adjusting the amount of water adhering according to different material requirements.

[0026] 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.
