Under the action of the servo motor 117, the lead screw 116 is driven to rotate inside the device frame 1. When the lead screw 116 rotates, the threaded joint of the lead screw 116 and the adjusting screw barrel 114 drives the adjusting screw barrel 114 to move in the guide groove. The inner sliding of 113 guides the adjusting screw 114 under the action of the guide slot 113. At this time, the adjusting screw 114 drives the second electric push rod 115 to move to the desired position. The user then operates the control button 101, so that the control button 101 controls the second electric push rod 115 to work, and the cleaning cotton 108 and the arc-shaped cleaning plate 109 are driven to contact the surface of the fixing roller body 105 under the action of the second electric push rod 115. The surface of the fixing roller body 105 is cleaned under the joint action of the cleaning cotton 108 and the arc-shaped cleaning plate 109. Subsequently, the user operates the control button 101 again, so that the control button 101 controls the driving motor 111 to work, and the driving motor 111 drives the second supporting member 112 and the first supporting member 106 to rotate on the surfaces of the second movable frame 104 and the first movable frame 103 respectively, thereby adjusting the angle of the fixing roller body 105, so that the cleaning cotton 108 and the arc-shaped cleaning plate 109 can clean different positions of the fixing roller body 105.

[0033] Then, the user operates the control button 101 again, so that the control button 101 controls the pump body 45 inside the fixed box 44 to work. Under the action of the pump body 45, the dust on the surface of the device frame 1 is sucked into the interior of the holding cavity 43 through the pump body 45, and the dust settles into the interior of the collection frame 42. Under the action of the collection frame 42, the dust is collected in a centralized manner. Then, the user pulls the door body 102 on the surface of the device frame 1, removes the door body 102 from the surface of the device frame 1, and then pulls the collection frame 42 inside the holding cavity 43. The collecting frame 42 drives the block 41 to slide inside the device frame 1, and the collecting frame 42 is guided under the action of the block 41, so that the collecting frame 42 is pulled out from the inside of the containing cavity 43, and the dust and other impurities inside the collecting frame 42 are processed to realize the function of the cleaning device to collect the cleaned dust in a centralized manner, so that the cleaning device can collect the dust cleaned from the surface of the fixing roller body 105 together when in use, so that the cleaning device can have a better cleaning effect on the fixing roller body 105 when in use.

[0034] Afterwards, the user needs to replace the cleaning cotton 108 and the arc-shaped cleaning plate 109 regularly. The user pulls the cleaning cotton 108 and the arc-shaped cleaning plate 109 upward, so that the connecting block 332 slides on the inner wall of the groove body 333. Under the joint action of the connecting block 332 and the groove body 333, the arc-shaped cleaning plate 109 and the fixing member 118 are guided. At this time, the connecting block 332 drives the anti-slip clamp 331 away from the inside of the fixing member 118. At this time, the fixing member 118 drives the first magnet 31 away from the surface of the second magnet 32, thereby The cleaning plate 109 and the fixing part 118 are removed from the output end of the second electric push rod 115, and the cleaning cotton 108 and the arc-shaped cleaning plate 109 are replaced to realize the function of the cleaning device to facilitate the replacement of the cleaning cotton 108 and the arc-shaped cleaning plate 109, so that when the cleaning device is used, it is convenient for the user to remove the cleaning cotton 108 and the arc-shaped cleaning plate 109 from the output end of the second electric push rod 115 to ensure the cleaning effect of the surface of the fixing roller body 105, so that the use effect of the cleaning device is better, and finally the use of the cleaning device is completed.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
