In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0027] The first embodiment of the present application proposes a cleaning device, which is used to clean the roller 200. It should be explained that the roller 200 can be a ceramic roller or a silicon roller. The cleaning device of the present application is suitable for cleaning rollers 200 made of various materials. Figures 1 to 3 As shown, the cleaning device includes a base 500, a rotating mechanism 400, a cleaning mechanism 100 and a moving mechanism 300. The base 500 includes a bottom plate 550, two mounting seats 540 and two first connecting members 510. The first connecting member 510 is a support plate arranged in a vertical direction, and the two first connecting members 510 are arranged opposite to each other so that the two ends of the roller 200 are supported on the top of the two first connecting plates respectively. The bottom plate 550 is arranged between the two first connecting members 510 and is located at the bottom of the moving mechanism 300. The two mounting seats 540 are respectively located on the outside of the two first connecting members 510, and the bottom plate 550 is located on the inside of the two first connecting members 510.

[0028] The rotating mechanism 400 is disposed on the base 500, and includes a second motor 410, a second reducer 440, a belt 420, and a first pulley 430. A second pulley is fixed to one end of the roller 200, and the first pulley 430 and the second pulley are connected by the belt 420 to realize linkage, so as to drive the roller 200 to rotate. The second motor 410 and the second reducer 440 are installed on the mounting seat 540, and the second motor 410 is connected to the first pulley 430 through the second reducer 440, so that the second motor 410 drives the roller 200 to rotate.

[0029] like Figure 2 As shown, the cleaning mechanism 100 includes a first cleaning member 101 and a second cleaning member 102. When the roller 200 is placed on the base 500, the first cleaning member 101 and the second cleaning member 102 are both located on the lower side of the roller 200. The first cleaning member 101 and the second cleaning member 102 respectively adopt different cleaning methods. Specifically, the first cleaning member 101 is used to separate the dirt on the outer peripheral surface of the roller 200 from the roller 200. The first cleaning member 101 includes but is not limited to grinding members such as sandpaper and sand blocks, which need to abut against the outer peripheral surface of the roller 200 to remove the dirt. Alternatively, the first cleaning member 101 can also be a laser head that can emit a laser toward the roller 200 to melt the dirt at high temperature. The second cleaning member 102 is used to wipe the roller 200 to remove the dirt and dust polished by the first cleaning member 101 or the melt formed by the first cleaning member 101 from the roller 200. The second cleaning member 102 includes but is not limited to a cloth soaked in water, a dust-free cloth soaked in pure water, etc. It should be noted that the second cleaning member 102 and the first cleaning member 101 are sequentially arranged at intervals along the first direction. It should be noted that the first direction and the second direction described below are both parallel to the length direction of the roller 200, but the first direction and the second direction point to opposite directions respectively.

[0030] like Figure 2As shown, the mobile mechanism 300 comprises a first motor 330, a first speed reducer 350, a lead screw, a moving member and a coupling 360. The lead screw is arranged above the base plate 550 and is arranged along the length direction of the roller 200. The first motor 330 and the first speed reducer 350 are both mounted on the mounting base 540, and the first motor 330 is connected with the lead screw through the first speed reducer 350 and the coupling 360 successively to drive the lead screw to rotate. The moving member is sleeved on the lead screw so that the moving member moves along the first direction. The cleaning mechanism 100 is connected with the moving member so that the cleaning mechanism 100 moves along the first direction, thereby, the first cleaning member 101 and the second cleaning member 102 clean the outer peripheral surface of the roller 200 successively. After the first cleaning member 101 separates the dirt on the outer circumference of the roller 200 from the roller 200 , if some of the dirt still re-attaches to the outer circumference of the roller 200 after being separated from the roller 200 , the second cleaning member 102 can wipe off the dirt attached to the roller 200 .

[0031] The cleaning device has a first mode. In the first mode, the rotating mechanism 400 drives the roller 200 to rotate, and the moving mechanism 300 drives the cleaning mechanism 100 to move along a first direction, so that the cleaning mechanism 100 can clean the outer circumference of the entire roller 200 in both the circumferential direction and the axial direction of the roller 200 in the first mode.

[0032] In some embodiments, the cleaning mechanism 100 further includes an air outlet 130. The cleaning device also has a second mode. In the second mode, the moving mechanism 300 drives the cleaning mechanism 100 to move along a second direction. The air outlet 130 is used to form a wind flow blowing toward the roller 200 to take away moisture and dust on the outer peripheral surface of the roller 200.

[0033] The second mode is often executed after the first mode, so that the air outlet member 130 of this embodiment can blow away the moisture remaining on the roller 200 by the second cleaning member 102 and the dust still attached to the roller 200 after cleaning by the first cleaning member 101 through the wind flow. Further, the air outlet member 130 can blow out hot air to dry the moisture on the roller 200. The moving directions of the first mode and the second mode are opposite, that is, the first direction is opposite to the second direction, so that after the cleaning device finishes cleaning the outer circumference of the entire roller 200, it can use the end position of the first mode as the starting position of the second mode, and move in the opposite direction of the first mode until it returns to the starting position of the first mode, thereby completing the further cleaning or drying of the outer circumference of the entire roller 200.

[0034] It is understandable that by setting the first mode and the second mode with opposite moving directions, the cleaning mechanism 100 can return to the starting position of the initial state after the entire cleaning device completes the first mode and the second mode, so that there is no need to move the idle stroke. It should be explained that the idle stroke refers to the movement stroke that does not have a corresponding effect after the working stroke, that is, the stroke in which the cleaning mechanism 100 does not have a cleaning effect. After the cleaning mechanism 100 cleans one roller 220, it returns to the initial position, so that the cleaning of the next roller 220 can continue, and there is no need to manually move the cleaning mechanism 100 to the initial position, thereby improving the efficiency of the cleaning device.

[0035] In some embodiments, Figure 2 As shown, the cleaning mechanism 100 also includes a first mounting member 110 and a second mounting member 120, and the first mounting member 110 is arranged above the second mounting member 120. The first cleaning member 101 and the second cleaning member 102 are both arranged on the second mounting member 120, and one end of the first mounting member 110 of the second cleaning member 102 is detachably connected to the second mounting member 120, and the other end is hinged to the second mounting member 120 through a hinge 140. It can be understood that the first mounting member 110 and the second mounting member 120 can also be hinged through the cooperation of the rotating shaft and the rotating hole. When both ends of the first mounting member 110 are connected to the second mounting member 120, an installation space for accommodating the roller 200 is formed between the first mounting member 110 and the second mounting member 120, and the roller 200 is arranged in the installation space.

[0036] Specifically, the cleaning mechanism 100 has an installed state and a disengaged state. In the disengaged state, one end of the first mounting member 110 that is detachable from the second mounting member 120 is separated from the second mounting member 120 and forms an opening, so that the roller 200 can be placed in the installation space through the opening or taken out from the installation space through the opening. In the installed state, both ends of the first mounting member 110 are connected to the second mounting member 120 to restrict the roller 200 in the installation space and prevent the roller 200 from falling off the cleaning mechanism 100. The opening and closing arrangement of the first mounting member 110 and the second mounting member 120 in this embodiment facilitates the disassembly and assembly of the roller 200.

[0037] Furthermore, the air outlet member 130 is disposed on the first mounting member 110. In the installed state, the combination of the first cleaning member 101 and the second cleaning member 102 and the air outlet member 130 are respectively located on both sides of the roller 200. It can be understood that in some embodiments, the second mounting member 120 is disposed below the roller 200, and the first mounting member 110 is disposed above the roller 200, so that Figure 2As shown, the two cleaning members are located below the roller 200, and the air outlet member 130 is located above the roller 200. Alternatively, in other embodiments, the first mounting member 110 is disposed below the roller 200, and the second mounting member 120 is disposed above the roller 200.

[0038] The height positions of the first mounting member 110 and the second mounting member 120 can be adjusted by the cooperation of the second connecting member 150 and the third connecting member 160 (detailed description will be given later). For example, the first cleaning member 101 is sandpaper and the second cleaning member 102 is a cloth soaked in water. In the first stroke, the positions of the first cleaning member 101 and the second cleaning member 102 are raised so that the first cleaning member 101 and the second cleaning member 102 are both in contact with the roller 200. In the second stroke, the positions of the first cleaning member 101 and the second cleaning member 102 are lowered so that the first cleaning member 101 and the second cleaning member 102 are separated from the roller 200, and the height of the air outlet member 130 is lowered accordingly, so that the distance between the air outlet member 130 and the roller 200 is reduced to enhance the drying effect of the air outlet member 130.

[0039] In some embodiments, the cleaning mechanism 100 further includes a second connecting member 150 and a third connecting member 160. The second connecting member 150 and the third connecting member 160 are slidably connected, the second connecting member 150 is connected to the moving mechanism 300, and the third connecting member 160 is connected to the cleaning mechanism 100. By adjusting the position of the second connecting member 150 relative to the third connecting member 160, the height of the cleaning mechanism 100 is adjusted, so as to adjust the position of the combination of the first cleaning member 101 and the second cleaning member 102 and the air outlet member 130 relative to the roller 200 in the vertical direction.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, the moving mechanism 300 also includes a moving member and a guide member 310. The moving member is a lead screw nut, the guide member 310 is mounted on the bottom plate 550, and the lead screw nut is arranged in the guide member 310. A slide groove 320 is provided on the guide member 310 along the length direction of the roller shaft 200, and the slide groove 320 is arranged at the top of the guide member 310. The second connecting member 150 is penetrated through the slide groove 320 and connected to the lead screw nut, so that the slide groove 320 limits the rotation of the second connecting member 150.

[0041] In some embodiments, the moving mechanism 300 includes two first stoppers 340. The two first stoppers 340 are mounted on the guide member 310, and the two first stoppers 340 are disposed at both ends of the slide slot 320 and above the slide slot 320 to define two extreme positions of the cleaning mechanism 100 in the length direction of the roller 200.

[0042] In some embodiments, Figure 2As shown, one of the second connecting member 150 and the third connecting member 160 is provided with a positioning groove in the vertical direction, and the other is provided with a limiting hole. The cleaning mechanism 100 has a locking state and an adjustment state. In the locking state, the locking member 170 is inserted into the positioning groove and the limiting hole, and limits the relative displacement of the second connecting member 150 and the third connecting member 160. In the adjustment state, the locking member 170 can slide relative to the length direction of the positioning groove, so that the third connecting member 160 can slide relative to the second connecting member 150.

[0043] In some embodiments, a bearing is disposed at one end of the roller shaft 200. A bearing receiving groove for receiving the bearing is disposed on the first connecting member 510, and the bearing receiving groove penetrates the first connecting member 510 along the length direction of the roller shaft 200. At least two second stoppers 530 are disposed on the first connecting member 510, and at least one second stopper 530 is disposed on both sides of the first connecting member 510 along the length direction of the roller shaft 200. The projection of the second stopper 530 along the length direction extends to the projection area of ​​the bearing receiving groove, so that when the bearing is installed in the bearing receiving groove, the second stopper 530 can limit the displacement of the bearing along the length direction.

[0044] In some embodiments, a rotating member 520 is provided on the first connecting member 510. The rotating member 520 is rotatably connected to the first connecting member 510, and the rotating shaft of the rotating member 520 is parallel to the rotating shaft of the roller shaft 200. The rotating member 520 is used to abut against the outer circumference of the roller shaft 200 to support the roller shaft 200, so as to reduce the friction between the roller shaft 200 and the first connecting member 510, so as to stabilize the rotation of the roller shaft 200. Further, a plurality of rotating members 520 are provided to define a gap between the outer circumference of the roller shaft 200 and the first connecting member 510, so as to reduce the friction between the roller shaft 200 and the first connecting member 510.

[0045] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
