[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Please see Figure 1 The preferred embodiment of this utility model provides a roller cleaning and wiping device, including a cleaning drive 1, a mounting plate 2, a bracket 3 and a roller 4. The mounting plate 2 is fixedly connected to the bracket 3. The cleaning drive 1 is used to drive the mounting plate 2 to rotate, so that the mounting plate 2 and the bracket 3 rotate together, simplifying the number of power sources.

[0026] The cleaning drive component 1 includes a drive cylinder 11. The cylinder has a simple structure, which further simplifies the structure. There are two drive cylinders 11, which are respectively connected to the two ends of the mounting plate 2, which helps to ensure the smooth rotation of the mounting plate 2.

[0027] The mounting plate 2 is provided with a solvent box 21 and a first strip cleaning component 20. The solvent box 21 is used to provide cleaning agent to the first strip cleaning component 20, which is used to clean the roller 4 with the cleaning agent. The hanger 3 is provided with a second strip cleaning component 30, which is used to remove residual impurities and cleaning agent from the roller 4. The first strip cleaning component 20 and the second strip cleaning component 30 are spaced apart. The roller 4 is located between the first strip cleaning component 20 and the second strip cleaning component 30, and all three are in the same length direction. When the first strip cleaning component 20 abuts against the roller 4, the second strip cleaning component 30 is spaced apart from the roller 4. When the second strip cleaning component 30 abuts against the roller 4, the first strip cleaning component 20 is spaced apart from the roller 4. Since the roller 4 is placed between the first strip-shaped cleaning component 20 and the second strip-shaped cleaning component 30, cleaning agent is supplied to the first strip-shaped cleaning component 20 through the solvent box 21. The cleaning drive 1 drives the mounting plate 2 to rotate, causing the first strip-shaped cleaning component 20 to come into contact with the surface of the roller 4. Rotating the roller 4 allows the first strip-shaped cleaning component 20 to repeatedly wipe the surface of the roller 4. After the surface of the roller 4 is cleaned, the cleaning drive 1 further drives the mounting plate 2 to rotate, causing the second strip-shaped cleaning component 30 to come into contact with the roller 4 and rotate, allowing the second strip-shaped cleaning component 30 to wipe away any remaining impurities and cleaning agent on the roller 4. The entire process is automated, improving cleaning efficiency.

[0028] The mounting plate 2 is provided with a fixing block 23. The piston rod of the drive cylinder 11 is hinged to the fixing block 23. The drive cylinder 11 can control the mounting plate 2 to rotate, so that it is in an inclined state, so that the cleaning agent in the solvent box 21 can be output from the liquid outlet 211 and wet the cleaning sponge 22, so as to keep the cleaning sponge 22 moist and improve the cleaning effect of the roller 4.

[0029] Please see Figure 1 and Figure 4 Specifically, the piston rod of the drive cylinder 11 is connected to a Y-type connector 12. The fixing block 23 is provided with a first through hole 231. Both ears of the Y-type connector 12 are provided with second through holes 121. The first through hole 231 and the second through hole 121 are coaxially arranged, and a connector pin 122 passes through the first through hole 231 and the second through hole 121. The piston rod of the drive cylinder 11 is hinged to the mounting plate 2 through the cooperation of the connector pin 122 with the first through hole 231 and the second through hole 121. This ensures the connection strength between the two and allows them to rotate relative to each other, so that the drive cylinder 11 can drive the mounting plate 2 more stably.

[0030] The device also includes a mounting bracket (not shown in the figure), on which the cylinder body of the drive cylinder 11 is rotatably mounted. Please refer to [link to relevant documentation]. Figure 2In this embodiment, the end of the through shaft 34 away from the connecting strip 33 is rotatably connected to the fixing frame through the bearing 341, so that the mounting plate 2 has a fulcrum when rotating, which helps to ensure the accuracy of the rotation angle of the mounting plate 2.

[0031] Please see Figure 1 The first strip-shaped cleaning component 20 includes a cleaning sponge 22, a solvent box 21 and the cleaning sponge 22 are staggered, and the solvent box 21 is provided with a number of liquid outlet holes 211 on the side near the cleaning sponge 22. The mounting plate 2 is provided with a number of liquid inlet holes 24. The liquid outlet holes 211 and the liquid inlet holes 24 are connected by a pipe (not shown in the figure). The liquid inlet holes 24 are all connected to the cleaning sponge 22. When the mounting plate 2 is tilted, the liquid outlet holes 211 deliver the cleaning agent in the solvent box 21 to the liquid inlet holes 24 through the pipe. The cleaning agent then flows out from the liquid inlet holes 24 and wets the cleaning sponge 22, ensuring that the cleaning sponge 22 is always in a wet state.

[0032] Specifically, the outlet holes 211 are arranged in two rows. The first outlet hole 211 is located above the second outlet hole 211. The first outlet hole 211 is connected to the inlet hole 24 through a pipe, or the second outlet hole 211 is connected to the inlet hole 24 through a pipe. Several inlet holes 24 and several outlet holes 211 can be detachably connected with quick-connect fittings 241. When there is a lot of cleaning agent in the solvent box 21, the first outlet hole 211 and the inlet hole 24 are connected, and the second outlet hole 211 is blocked with quick-connect fittings 241. It should be noted that the initial height of the cleaning agent is lower than the first outlet hole 211, so that no cleaning agent will flow out when the mounting plate 2 is in a horizontal state. The cleaning agent will flow to the cleaning sponge 22 when the mounting plate 2 is tilted. When a large amount of cleaning agent is consumed, the mounting plate 2 is placed in a horizontal position, and the second drain hole 211 is connected to the inlet hole 24. Then, the mounting plate 2 is rotated so that the remaining cleaning agent can flow to the cleaning sponge 22, preventing excessive cleaning agent residue in the solvent box 21 and avoiding waste.

[0033] Please see Figure 5 The mounting plate 2 has a snap-fit ​​notch 25 and a snap-fit ​​strip 26 on one side. The two ends of the snap-fit ​​strip 26 are detachably connected to the inner wall of the snap-fit ​​notch 25. The snap-fit ​​strip 26 and the snap-fit ​​notch 25 together form a snap-fit ​​groove 27. Part of the cleaning sponge 22 is snapped into the snap-fit ​​groove 27, and several liquid inlet holes 24 are connected to the snap-fit ​​groove 27. The two ends of the snap-fit ​​strip 26 are connected to the inner wall of the snap-fit ​​notch 25 by bolts (not shown in the figure). By disassembling and assembling the snap-fit ​​strip 26, the cleaning sponge 22 can be separated from and snapped into the snap-fit ​​groove 27, which is convenient for replacement of the cleaning sponge 22 after it becomes worn out.

[0034] Please see Figure 2The second strip cleaning component 30 includes a wiping cloth roll 31. Specifically, the hanger 3 includes a roller 32 and two connecting strips 33. The roller 32 is connected between the two connecting strips 33. The wiping cloth roll 31 is wound around the roller 32. Both connecting strips 33 are connected to the mounting plate 2 through a through shaft 34. During the rotation of the mounting plate 2, the two connecting strips 33 swing accordingly, causing the roller 32 to move towards or away from the roller 4.

[0035] The device also includes a roller drive (not shown in the figure), which drives the roller 4 to rotate and automatically controls the rotation of the roller 4, reducing labor costs.

[0036] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
