[0034] See also Figure 1 Now, the roller wiping device provided in the embodiment of the present application is described. The roller wiping device provided in the embodiment of the present application is used to clean the roller 70.
[0035] Reference Figure 1 The wiping roller device includes a reeling and unreeling mechanism 10 and a pressing and wiping mechanism 20.
[0036] Reference Figure 1 and Figure 2 The unwinding and rewinding mechanism 10 is used to rewind and rewind the wiping belt 50. The wiping belt 50 is a tool for wiping and cleaning the roller 70. It functions as a rag, but it can be automatically unwinded and rewound, taking away the dirty part that has been wiped, and wiping with the new, unwiped part to ensure the cleaning effect of the roller 70. The unwinding and rewinding mechanism 10 includes an unwinding mechanism 11 and a rewinding mechanism 12. The unwinding mechanism 11 and the rewinding mechanism 12 are arranged at intervals. The wiping belt 50 is wound around the unwinding mechanism 11 and the rewinding mechanism 12. The unwinding mechanism 11 is used to unwind the wiping belt 50, and the rewinding mechanism 12 is used to rewind the wiping belt 50. The unwinding mechanism 11 and the rewinding mechanism 12 can be installed on the frame 60 on one side of the roller 70. The unwinding mechanism 11 and the rewinding mechanism 12 can be arranged at intervals up and down, for example, the unwinding mechanism 11 is located above the rewinding mechanism 12. The wiping tape 50 is in a roll and installed on the unwinding mechanism 11. When in use, it is unwound from the unwinding mechanism 11 and then rewound by the rewinding mechanism 12. During the process from unwinding to rewinding, the wiping tape 50 can be pressed onto the roller 70 by the pressing and wiping mechanism 20. Through the rewinding movement and / or the rotation of the roller 70, friction occurs between the wiping tape 50 and the roller 70, thereby cleaning the surface of the roller 70. Specifically, the wiping tape can be a cloth, preferably a non-woven fabric.
[0037] Reference Figure 1 and Figure 2 The wiping mechanism 20 includes a wiping roller 21 and a first driver 22. The wiping roller 21 is located between the unwinding mechanism 11 and the winding mechanism 12. The wiping roller 21 has a concave arc surface 213 that matches the outer peripheral surface shape of the roller 70. The first driver 22 can drive the wiping roller 21 to approach or move away from the roller 70. The concave arc surface 213 pushes the wiping belt 50 to contact the roller 70. The wiping belt 50 unwound by the unwinding mechanism 11 passes through the concave arc surface 213 in sequence and is wound on the winding mechanism 12. The wiping roller 21 can approach or move away from the roller 70 along the first direction X under the drive of the first driver 22. Since the wiping tape 50 unwound by the unwinding mechanism 11 passes through the concave arc surface 213 and is wound up by the winding mechanism 12, when the wiping roller member 21 approaches the roller 70, the wiping tape 50 is sandwiched between the concave arc surface 213 and the roller 70. As the roller 70 rotates and / or the wiping tape 50 is wound up, friction occurs between the roller 70 and the wiping tape 50, thereby cleaning the roller 70. Since the concave arc surface 213 of the wiping roller member 21 matches the shape of the outer peripheral surface of the roller 70, the concave arc surface 213 can fit the peripheral surface of the roller 70 (sandwiching the wiping tape 50), which is a surface contact, the contact area is larger during cleaning, the cleaning is more stable, and the cleaning effect is better.
[0038] The first direction X may be a horizontal direction, or may be at an angle to the horizontal direction. Specifically, the first driver 22 may be a cylinder or a linear motor, and the wiping roller 21 may be connected to the frame 60 via a guide rail, and the length direction of the guide rail is along the first direction X, so that the wiping roller 21 can move in the first direction X along the guide rail, which is more stable.
[0039] Reference Figure 1 , Figure 3 and Figure 4 The wiping roller member 21 includes a main body 211 and a plurality of strip structures 212. One end of the main body 211 is connected to the first driver 22, and the other end is provided with a plurality of strip structures 212 at intervals. One end of each strip structure 212 facing away from the main body 211 protrudes from the main body 211 and is arranged in a concave arc shape, and together forms a concave arc surface 213. The main body 211 is connected to the first driver 22, so that it can move closer to or away from the roller 70 along the first direction X. The strip structure 212 protrudes from the main body 211, and a plurality of strip structures 212 are arranged on the main body 211. The strip structure 212 protrudes from the main body 211, and one end of the protruding end is arranged in an arc shape. Through this arc arrangement, the ends of the strip structures 212 together form a concave arc surface 213. Therefore, when cleaning, the main body 211 drives the strip structure 212 to approach the roller 70, so that the ends of the strip structure 212 press the wiping belt 50 on the roller 70. That is, the main body 211 does not contact the wiping belt 50 or the roller 70 , but the wiping belt 50 is contacted by the plurality of protruding strip structures 212 .
[0040] In some embodiments, reference Figure 4The main body 211 has a plane, and multiple strip structures 212 are arranged on the plane, but the protruding height values of each strip structure 212 are not equal. For example, the height of the strip structure 212 protruding from the plane decreases from top to bottom, and then increases, thereby forming a concave arc.
[0041] In some embodiments, reference Figure 3 The main body 211 has a concave arc surface 213, and each strip structure 212 is arranged on the concave arc surface 213. The height of each strip structure 212 protruding from the concave arc surface 213 is equal, so that the protruding end of each strip structure 212 also forms a concave arc surface 213. Specifically, the cross-section of the strip structure 212 is semicircular or circular, and can make line contact with the circumferential surface of the roller 70 through the circumferential surface, and multiple strip structures 212 form multiple line contacts, which are combined together to form surface contact. Preferably, the strip structure 212 is a rubber roller, which has a certain elasticity and can be deformed when pressed against the roller 70, thereby changing from line contact to surface contact, further improving the cleaning effect on the roller 70. The length direction of the strip structure 212 is parallel to the axial direction of the roller 70.
[0042] Reference Figure 1 and Figure 3 The wiping mechanism 20 further includes a first roller 23, a second roller 24 and two connecting frames 25. The two connecting frames 25 are arranged at both ends of the wiping roller 21. The first roller 23 is rotatably connected to one end of the connecting frame 25 close to the unwinding mechanism 11, and the second roller 24 is rotatably connected to one end of the connecting frame 25 close to the winding mechanism 12. The wiping tape 50 unwound by the unwinding mechanism 11 passes through the first roller 23, the concave arc surface 213 and the second roller 24 in sequence, and is wound up by the winding mechanism 12. The first roller 23 and the second roller 24 arranged in the wiping mechanism 20 can make the wiping tape 50 pass through the wiping roller 21 more smoothly.
[0043] Reference Figure 1 The winding mechanism 12 includes a first air-expanding shaft 111 and a second driver. The first air-expanding shaft 111 is rotatably disposed on the frame 60, and the second driver is used to drive the air-expanding shaft to rotate. The first air-expanding shaft 111 can fix or loosen the wipe belt 50 by expanding and contracting. The second driver drives the air-expanding shaft to rotate, thereby winding the wipe belt 50 on the air-expanding shaft. The second driving mechanism can be a motor.
[0044] Reference Figure 1The unwinding mechanism 11 includes a second air-expanding shaft 121 and a damper. The second air-expanding shaft 121 is rotatably disposed on the frame 60. The damper is used to provide resistance when the second air-expanding shaft 121 rotates. The second air-expanding shaft 121 can fix or loosen the wipe belt 50 by expanding and contracting. The resistance provided by the damper can prevent the unwinding mechanism 11 and the rewinding mechanism 12 from rotating too fast, thereby failing to tighten the wipe belt 50 and affecting the cleaning effect.
[0045] Reference Figure 1 and Figure 2 The wiping roller device also includes an atomizing spray mechanism 30 located above the wiping roller member 21. The atomizing spray mechanism 30 includes a cleaning liquid supply pipeline and an atomizing nozzle 31. The atomizing nozzle 31 is connected to the cleaning liquid supply pipeline. The atomizing nozzle 31 is also connected to an external high-pressure gas circuit to spray the supplied cleaning liquid through high-pressure gas. The cleaning liquid supply pipeline supplies the cleaning liquid to the atomizing nozzle 31. The atomizing nozzle 31 sprays the cleaning liquid into mist with the help of external high-pressure gas. The mist cleaning liquid falls on the roller 70 below. The wiping belt 50 wipes the roller 70 with the cleaning liquid. The cleaning liquid supply pipeline specifically includes a reservoir, a tube body and a peristaltic pump. The reservoir is filled with cleaning liquid. The tube body connects the reservoir and the atomizing nozzle 31. The peristaltic pump is arranged on the tube body. The cleaning liquid in the reservoir is continuously transported to the atomizing nozzle 31 through the peristaltic pump. A plurality of atomizing nozzles 31 can be provided, and connected to the frame 60 via a mounting frame, and the angle of the atomizing nozzle 31 can be adjusted on the mounting frame.
[0046] Reference Figure 1 and Figure 2 The wiping roller device also includes a blowing mechanism 40 for blowing air toward the roller 70, using positive pressure blowing to quickly evaporate the atomized cleaning agent scattered to the periphery. The blowing mechanism 40 can adjust the air volume to adjust the evaporation amount.
[0047] Reference Figures 1 to 4 The embodiment of the present application further provides a rolling device, including a roller 70 and a wiping roller device as described above, wherein the wiping roller device is arranged on one side of the roller 70.
[0048] Since the rolling equipment of the embodiment of the present application includes the wiping roller device in any of the above embodiments, it has the beneficial effects brought by the wiping roller device in any of the above embodiments, which will not be described in detail here.
[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
