[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-Figure 7 As shown, the online wiping roller device of the present invention has a sophisticated and efficient structural design and mainly includes the following core components: a base 1, a first bracket 2, a second bracket 3, an unwinding roller 4, a cleaning liquid spraying device 5, a pressure rod 6, a winding roller 7, a motor 8, a third bracket 9, a guide roller 10, a working roller 11, a cylinder 12, a spray port 13, a cleaning liquid drying device 14 (the device is further subdivided into an air compression pump 141 and an air knife 142) and a fixed plate 15.

[0030] like Figure 1 As shown, the base 1 forms the stable foundation of the entire device, with the first bracket 2 and second bracket 3 fixed to it. These two brackets not only provide support for the other components but also ensure the stability and firmness of the device. The unwinding roller 4 and the winding roller 7 are rotatably mounted on the second bracket 3 and the first bracket 2, respectively. Their main function is to unwind and rewind the dust-free cloth. The working roller 11, as the object to be cleaned, is placed in the transmission path of the dust-free cloth and is stably supported on the third bracket 9.

[0031] like Figure 5 As shown, the dust-free cloth is a key material for cleaning in this device. Its conveying path: it is slowly discharged from the unwinding roller 4, is precisely guided by the guide roller 10 and moderately pressed by the pressure rod 6, and is finally tightly wound on the winding roller 7. During this conveying process, the dust-free cloth is in close contact with the surface of the working roller 11. Through the relative movement between the two, the working roller 11 is effectively cleaned.

[0032] To drive the unwinding roller 4 and winding roller 7, motors 8 are installed on the second bracket 3 and first bracket 2, respectively. These motors 8 transmit power to the unwinding roller 4 and winding roller 7 through a transmission mechanism (such as gears and chains), thereby achieving continuous and smooth transportation of the dust-free cloth. The speed of motor 8 can be adjusted according to actual working requirements to ensure that the relative speed between the dust-free cloth and the working roller 11 is both moderate and efficient.

[0033] like Figure 2As shown, the guide roller 10 is cleverly mounted on the first bracket 2. Its primary function is to ensure that the dust-free cloth remains stable during transport, without shifting or wrinkling. The guide roller 10 is rotatably mounted on a bearing seat, which is securely fixed to the first bracket 2. By adjusting the position and angle of the guide roller 10, the dust-free cloth conveyance can be further optimized.

[0034] The pressure rod 6 is a key component of this device. Its primary function is to ensure good contact and friction between the dust-free cloth and the work roller 11. The pressure rod 6 is movable, driven by a cylinder 12 mounted on a fixed plate 15. By adjusting the stroke and pressure of the cylinder 12, the contact force between the dust-free cloth and the work roller 11 and the cleaning effect can be precisely controlled.

[0035] like Figure 2-Figure 3 As shown, the cleaning liquid spraying device 5 is another key component in this device, and its main task is to spray cleaning liquid on the dust-free cloth before the dust-free cloth contacts the working roller 11. The cleaning liquid spraying device 5 is mainly composed of a pump body, a nozzle and a spray port 13. The pump body is mounted on the first bracket 2, with its suction end tightly connected to the cleaning liquid storage container, and the discharge end is connected to the nozzle. The nozzle is carefully arranged on the conveying path of the dust-free cloth, and its spray port 13 is arranged toward the dust-free cloth. Specifically, the cleaning liquid storage container is an alcohol tank. When the cleaning liquid spraying device 5 is started, the pump body will draw alcohol from the alcohol tank and spray it evenly on the dust-free cloth through the nozzle, thereby wetting it. When the wetted dust-free cloth contacts the working roller 11 during the conveying process, it can more effectively remove dirt and residue on the surface of the working roller 11.

[0036] Yet, only rely on cleaning fluid and the wiping of dust-free cloth and be not enough, because the work roller 11 surface after wiping may remain some cleaning fluid.In order to solve this problem, we have installed the cleaning fluid drying device 14 on the base 1.

[0037] like Figure 2-Figure 4As shown, the cleaning liquid drying device 14 mainly consists of an air compressor 141 and an air knife 142. The air compressor 141 is mounted on the base 1, and its air outlet is closely connected to the air knife 142. The air jets of the air knife 142 are arranged toward one side of the work roll 11, and the number and arrangement of the jets can be adjusted according to the width of the work roll 11 and the drying requirements. After the work roll 11 is wiped with a dust-free cloth, the cleaning liquid drying device 14 is started. The air compressor 141 draws air through the air inlet, compresses it, and delivers it to the air knife 142. The compressed air in the air knife 142 is ejected at high speed through the jet outlet and blown onto the surface of the work roll 11. Due to the high speed of the compressed air, it can quickly remove any residual cleaning liquid on the surface of the work roll 11, thereby achieving a drying effect. At the same time, the air jets of the air knife 142 are arranged in the direction of the axis of the work roll 11 to ensure that the entire surface of the work roll 11 is evenly dried.

[0038] like Figure 1-7 As shown, when using this device, we follow the following steps: First, preparatory work is carried out, including checking whether all parts of the device are intact, ensuring that there are sufficient materials such as dust-free cloth and cleaning liquid, fixing the dust-free cloth roller sleeve to the unwinding roller 4, fixing the winding drum to the winding roller 7, adjusting the position and angle of the guide roller 10, and starting the air compression pump 141 and the pump body of the cleaning liquid spraying device 5 for inspection. Then, cleaning operations are carried out, including starting the motor 8 to drive the unwinding roller 4 and winding roller 7 to rotate, controlling the nozzle of the cleaning liquid spraying device 5 to spray alcohol onto the dust-free cloth, adjusting the stroke and pressure of the cylinder 12 to ensure good contact and friction between the dust-free cloth and the surface of the working roller 11. The dust-free cloth contacts and wipes the surface of the working roller 11 during the conveying process, and starting the air knife 142 of the cleaning liquid drying device 14 to spray compressed air onto the working roller 11 to dry its surface. Finally, the operation is completed, including stopping the motor 8 and the pump body of the cleaning liquid spraying device 5, turning off the air compression pump 141 and the air knife 142 of the cleaning liquid drying device 14, disassembling the winding drum and the dust-free cloth roller cover and replacing them with new dust-free cloth roller covers, and cleaning the dirt and residue on various components of the device.

[0039] The online roller wiping device of the present invention has many beneficial technical effects: by arranging the unwinding roller 4, the winding roller 7 and the cleaning liquid spraying device 5 to cooperate with each other, the continuous and uniform cleaning of the working roller 11 is achieved; the dust-free cloth contacts the working roller 11 after being moistened and wipes its surface, effectively removing dirt and residues; at the same time, the setting of the cleaning liquid drying device 14 can quickly dry the residual cleaning liquid on the surface of the working roller 11, avoiding secondary pollution; in addition, the device also realizes continuous and automatic cleaning operations, greatly improving work efficiency; the structural design and working principle of each component of the device have been optimized to ensure the stability and reliability of the device; finally, the device is suitable for cleaning operations of various types of working rollers 11, and has broad market application prospects and promotion value.
