[0026] The present application will be further described below in conjunction with the drawings:

[0027] As Figures 1 to 4 shown, the present application provides a stepless compensation belt cleaning device, the cleaning device is arranged on the rotating side 11 of the feeding belt 1, the floating cleaning mechanism 2 includes a shower assembly 21, a scraper assembly 22, a wiping assembly 23 and a compensation mechanism 24, the shower assembly 21, the scraper assembly 22 and the wiping assembly 23 are arranged in sequence along the moving direction of the rotating side 11 of the feeding belt 1, the rotating side 11 of the feeding belt 1 is adapted to cooperate with the shower assembly 21 prior to the scraper assembly 22 and the wiping assembly 23, the shower assembly 21 is adapted to spray water to the feeding belt 1, the compensation mechanism 24 is connected to the scraper assembly 22 and the wiping assembly 23, the compensation mechanism 24 is adapted to make the scraper assembly 22 and the wiping assembly 23 float to contact the surface of the feeding belt 1 in a direction perpendicular to the surface of the feeding belt 1, the scraper assembly 22 is used to remove the relatively firm block dust on the surface of the feeding belt 1, and the wiping assembly 23 is used to wipe the dirt and water stains on the surface of the feeding belt 1, so that the surface of the feeding belt 1 remains clean.

[0028] The compensation mechanism 24 can receive instructions from the system background, and actively control the squeegee assembly 22 and the wiping assembly 23 to increase the pressure on the feeding belt 1 when necessary, so as to effectively reduce the excessive wear between the squeegee assembly 22, the wiping assembly 23 and the feeding belt 1, thereby prolonging the service life of the system and reducing the maintenance cycle.

[0029] As shown in the embodiment shown in Figures 1 to 3 The compensation mechanism 24 includes a compensator 241 and a connecting plate 242, the connecting plate 242 is connected with the squeegee assembly 22 and the wiping assembly 23 in a plane parallel to the rotating side 11 of the feeding belt 1, the compensation direction of the compensator 241 and the connecting plate 242 is perpendicular to the rotating side 11 of the feeding belt 1, the connecting plate 242 has elastic deformation ability, the elasticity of the connecting plate 242 at the squeegee assembly 22 is greater than that at the wiping assembly 23, and when the compensator 241 drives the connecting plate 242 to compensate, the connecting plate 242 can drive the squeegee assembly 22 and the wiping assembly 23 to change the distance between them and the feeding belt 1, so as to realize the adjustment of the cleaning effect by changing the contact force, wherein the squeegee assembly 22 has stronger wear on the feeding belt 1, so the connecting plate 242 is designed as an elastic structure, when the squeegee assembly 22 is subjected to a larger external force, the connecting plate 242 can deform to a certain extent, thereby relieving the impact between the squeegee assembly 22 and the feeding belt 1, and protecting the feeding belt 1 and the squeegee assembly 22.

[0030] In some embodiments, the compensator 241 uses a pneumatic cylinder, and the control logic is simple and the failure rate is low.

[0031] In some embodiments, the compensator 241 uses a motor, and the connecting plate 242 is connected with the compensator 241 through a lead screw, the motor can realize precise control of the height of the connecting plate 242, realize stepless adjustment, and then finely control the contact force between the squeegee assembly 22 and the wiping assembly 23 connected with the connecting plate 242 and the feeding belt 1, thereby realizing the adjustment of the cleaning effect.

[0032] As shown in the embodiment shown in Figures 1 to 3 The number of wiping assemblies 23 is multiple, the connecting position of the compensator 241 and the connecting plate 242 is located at the central axis of the connecting line of all wiping assemblies 23 (see the dotted line at the compensator 241 in Figure 1 , so that the contact force between each wiping assembly 23 and the feeding belt 1 is similar, the cleaning effect is similar, and the wear degree can also be kept similar.

An elastic reset member 243 is provided between the connecting plate 242 and the scraper assembly 22, as well as between the connecting plate 242 and the wiping assembly 23. The elastic reset member 243 is suitable for bringing the scraper assembly 22 or the wiping assembly 23 closer to the connecting plate 242. Due to the vibration that will occur during the operation of the feeding belt 1, and the unevenness of the surface of the feeding belt 1, the elastic reset member 243 can be used to further alleviate the impact that may occur between the scraper assembly 22 and the wiping assembly 23 and the feeding belt 1, thereby protecting the feeding belt 1, the scraper assembly 22 and the wiping assembly 23.

The scraper holder 221 and the first lifting shaft 222 are rotatably connected. The compensators 241 on the left and right sides of the scraper holder 221 are independent of each other. After decoupling by the rotating structure, the two ends of the scraper holder 221 can be controlled to rise or fall respectively, so as to realize the tilt compensation of the scraper holder 221. This allows the scraper holder 221 to clean the feeding belt 1 in more ways.

The detachable design facilitates the replacement and maintenance of the scraper 223, thereby ensuring the cleaning effect and protecting the feed belt 1, preventing the worn scraper 223 from damaging the feed belt 1.

[0037] like Figures 1 to 3In the shown embodiment, the erasing assembly 23 comprises an erasing frame 231 and a second lifting shaft 232, the erasing frame 231 is parallel to the turning side 11 of the feeding belt 1, the second lifting shaft 232 and the connecting plate 242 are slidingly connected, the erasing frame 231 and the second lifting shaft 232 are rotationally connected, the compensators 241 on the left and right sides of the erasing frame 231 are independent of each other, and after decoupling by the rotating structure, the two ends of the erasing frame 231 can be respectively controlled to rise or fall, the inclination compensation of the erasing frame 231 is realized, so that the erasing frame 231 can have more forms to clean the feeding belt 1.

[0038] As shown in the embodiment, Figure 3 In the shown embodiment, one or more sponge strips 233 are detachably arranged on the erasing frame 231, the sponge strip 233 is a consumable part, and the detachable design can facilitate the replacement and maintenance of the sponge strip 233, thereby ensuring the cleaning effect.
