[0042] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0043] First, the roll cleaning device 100 according to an embodiment of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0044] As Figures 1 to 5 shown, the roll cleaning device 100 according to an embodiment of the present invention includes: a frame 1, a roll, at least one spray-brush module 10, and a residual liquid adsorption module 20.

[0045] Specifically, the roll 2 is rotatably disposed on the frame 1 about its own axis, the spray-brush module 10 is disposed on the frame 1, the spray-brush module 10 is configured to be adapted to spray a cleaning liquid onto the outer peripheral surface of the roll 2 and brush off the dirt on the outer peripheral surface of the roll 2, the spray-brush module 10 is provided with a negative pressure adsorption cover 11, the negative pressure adsorption cover 11 is adapted to collect the brushed-off dirt and / or cleaning liquid, the residual liquid adsorption module 20 and the spray-brush module 10 are distributed along the circumferential direction of the roll 2, the residual liquid adsorption module 20 is disposed on the frame 1, and the residual liquid adsorption module 20 is adapted to adsorb the cleaning liquid on the outer peripheral surface of the roll 2.

[0046] In other words, as Figures 1 to 5 shown, the roll cleaning device 100 according to an embodiment of the present invention mainly includes a frame 1, a roll, a spray-brush module 10, and a residual liquid adsorption module 20. Among them, the frame 1 can provide an installation position for other structures of the roll cleaning device 100, the roll 2 is rotatably installed on the frame 1 about its own axis, the number of the spray-brush modules 10 can be one or more, and it can be selected according to actual needs. The spray-brush module 10 is installed on the frame 1, and the spray-brush module 10 can correspond to the position of the roll 2, so that the spray-brush module 10 can spray a cleaning liquid onto the outer peripheral surface of the roll 2, and the sprayed cleaning liquid can soften the toner (i.e., dirt) on the outer peripheral surface of the roll 2, so as to facilitate subsequent brushing off the softened toner from the outer peripheral surface of the roll 2 by the spray-brush module 10.

[0047] As Figure 1 and Figure 2As shown in the figure, the spraying and brushing module 10 is provided with a negative pressure adsorption hood 11. Through the negative pressure adsorption hood 11, the carbon powder and cleaning liquid brushed off can be collected by negative pressure, which can effectively avoid secondary pollution during the cleaning process and is conducive to cleaning the outer peripheral surface of the rolling roll 2 thoroughly. The residual liquid adsorption module 20 and the spraying and brushing module 10 are distributed along the circumferential direction of the rolling roll 2. The residual liquid adsorption module 20 is installed on the frame 1, and the position of the residual liquid adsorption module 20 can correspond to that of the rolling roll 2. During use, the residual liquid adsorption module 20 is located downstream of the spraying and brushing module 10. Through the residual liquid adsorption module 20, the cleaning liquid remaining on the outer peripheral surface of the rolling roll 2 can be adsorbed, which can ensure the dryness of the outer peripheral surface of the rolling roll 2 during the subsequent roll pressing process, thereby effectively avoiding the pollution of the product (such as the electrode sheet) by the cleaning liquid.

[0048] Therefore, for the rolling roll cleaning device 100 provided by this embodiment, through the arranged spraying and brushing module 10, the carbon powder on the outer peripheral surface of the rolling roll 2 can be softened, and the softened carbon powder can be brushed off, which is convenient for cleaning the outer peripheral surface of the rolling roll 2 thoroughly. Moreover, through the arranged residual liquid adsorption module 20, the cleaning liquid remaining on the outer peripheral surface of the rolling roll 2 can be cleaned up, which can ensure the production quality of the electrode sheet.

[0049] In some embodiments of the present utility model, the rolling roll cleaning device 100 includes a plurality of spraying and brushing modules 10. The plurality of spraying and brushing modules 10 are distributed along the circumferential direction of the rolling roll 2. In the circumferential direction of the rolling roll 2, the plurality of spraying and brushing modules 10 are located on one side of the residual liquid adsorption module 20.

[0050] That is to say, as Figure 1 shown, a plurality of spraying and brushing modules 10 are installed on the frame 1. The plurality of spraying and brushing modules 10 can be distributed along the circumferential direction of the rolling roll 2. Through the plurality of spraying and brushing modules 10, multiple cleaning operations can be performed on the outer peripheral surface of the rolling roll 2, which is conducive to cleaning the outer peripheral surface of the rolling roll 2 thoroughly and can effectively improve the cleanliness of the outer peripheral surface of the rolling roll 2. Moreover, one of the plurality of spraying and brushing modules 10 can be used as a spare. When the other spraying and brushing modules 10 are damaged or malfunction, etc., the spare spraying and brushing module 10 can be used to replace the damaged or malfunctioning spraying and brushing module 10 to work, thereby effectively ensuring the reliability of the rolling roll cleaning device 100. In the circumferential direction of the rolling roll 2, the plurality of spraying and brushing modules 10 are located on one side of the residual liquid adsorption module 20. Thus, the residual liquid adsorption module 20 can adsorb the cleaning liquid remaining on the outer peripheral surface of the rolling roll 2 after multiple cleaning processes, which can ensure the dryness of the outer peripheral surface of the rolling roll 2 during the subsequent roll pressing process.

[0051] Furthermore, in the circumferential direction of the rolling roll 2, the angle between adjacent spraying and brushing modules 10 is about 24 degrees. That is, in two adjacent spraying and brushing modules 10, the included angle between the line connecting the axis of the flexible brush roll 13 of the first spraying and brushing module 10 and the axis of the rolling roll 2 and the line connecting the axis of the flexible brush roll 13 of the second spraying and brushing module 10 and the axis of the rolling roll 2 is about 24 degrees.

[0052] According to one embodiment of the present invention, a negative pressure adsorption hood 11 is provided on a frame 1, and the negative pressure adsorption hood 11 is provided with an installation space. The brushing module 10 also includes: a nozzle assembly 12, a flexible brush roller 13 and a driving member. The nozzle assembly 12 is provided on the frame 1, and the nozzle assembly 12 is suitable for spraying cleaning liquid onto the outer peripheral surface of the roller 2. The flexible brush roller 13 extends along the axial direction of the roller 2, and the flexible brush roller 13 is rotatably provided around its own axis in the installation space. The bristles of the flexible brush roller 13 are suitable for abutting against the outer peripheral surface of the roller 2. The driving member is provided on the frame 1, and the driving member is connected to one end of the flexible brush roller 13. The driving member is used to drive the flexible brush roller 13 to rotate to brush the dirt off the outer peripheral surface of the roller 2.

[0053] Specifically, if Figure 1 As shown, the spray brush module 10 mainly includes a nozzle assembly 12, a negative pressure adsorption cover 11, a flexible brush roller 13 and a driving part, wherein the nozzle assembly 12 can be fixed to the frame 1, and the nozzle assembly 12 is provided with a plurality of nozzles, and the flow rate, atomization, spraying angle and spray width of the nozzles can be adjusted. The plurality of nozzles are spaced apart and distributed along the axial direction of the roller 2, and the carbon powder area on the outer peripheral surface of the roller 2 can be sprayed with cleaning liquid through the plurality of nozzles; the negative pressure adsorption cover 11 is fixedly connected to the frame 1, and the negative pressure adsorption cover 11 is provided with an installation space suitable for installing the flexible brush roller 13, and the flexible brush roller 13 is rotatably arranged around its own axis in the installation space.

[0054] Furthermore, the bristles of the flexible brush roller 13 can abut against the outer peripheral surface of the roller 2, so that the carbon powder on the surface of the roller 2 can be brushed off when the flexible brush roller 13 rotates; the driving member can be a motor, and the driving member can be installed on the frame 1. The output end of the driving member can be connected to one end of the flexible brush roller 13 through transmission, so that the driving member can drive the flexible brush roller 13 to rotate, which is beneficial to cleaning the carbon powder on the surface of the roller 2, and the rotation speed of the flexible brush roller 13 can be controlled according to demand to ensure the cleanliness of the surface of the roller 2.

[0055] In this embodiment, the flexible brush roller 13 can be driven to rotate by the driving member, and the flexible brush roller 13 can clean the carbon powder on the surface of the roller 2. Compared with the prior art that uses a scraper to clean the carbon powder, the spray brush module 10 of the utility model effectively avoids damage to the roller 2 during the cleaning process, and the flexible brush roller 13 is not easily damaged, thereby effectively reducing the maintenance cost of the roller 2 equipment.

[0056] Furthermore, the rotation speed of the flexible brush roller 13 can be controlled by the provided driving member, so that the rotation speed of the flexible brush roller 13 can be adjusted according to the rotation speed of the roller 2 , thereby ensuring the cleanliness of the outer peripheral surface of the roller 2 .

[0057] According to some embodiments of the present invention, the flexible brush roller 13 can be detachably mounted on the frame 1 via a connecting piece.

[0058] In some embodiments of the present invention, the negative pressure adsorption cover 11 is provided with a negative pressure chamber 111, and the side of the negative pressure adsorption cover 11 close to the installation space is provided with an adsorption hole 112, the adsorption hole 112 is connected to the negative pressure chamber 111, and the negative pressure adsorption cover 11 is provided with a first negative pressure adsorption port 113 and a first liquid supply pipe 114, and the first negative pressure adsorption port 113 and the first liquid supply pipe 114 are respectively connected to the negative pressure chamber 111.

[0059] That is to say, if Figure 2 and Figure 3 As shown, the negative pressure adsorption cover 11 has a negative pressure chamber 111. A plurality of adsorption holes 112 are provided on the side of the negative pressure adsorption cover 11 close to the installation space, connected to the negative pressure chamber 111. Furthermore, the negative pressure adsorption cover 11 is provided with a first negative pressure adsorption port 113 and a first liquid supply pipe 114 connected to the negative pressure chamber 111. During use, the first negative pressure adsorption port 113 is connected to a negative pressure generating device, thereby generating a negative pressure within the negative pressure chamber 111. This allows the adsorption holes 112 to utilize the negative pressure to adsorb carbon powder, cleaning fluid, or carbon sludge formed by a mixture of carbon powder and cleaning fluid. Furthermore, the first liquid supply pipe 114 can be used to supply cleaning fluid to the negative pressure chamber 111. The cleaning fluid can be mixed with the carbon powder or carbon sludge to form a carbon-water mixture, and the first negative pressure adsorption port 113 can extract the carbon-water mixture from the negative pressure chamber 111.

[0060] Therefore, the first liquid supply pipe 114 can provide cleaning liquid to the negative pressure chamber 111, which is conducive to extracting the carbon mud in the negative pressure chamber 111, avoiding the occurrence of blockage problems, and effectively improving the reliability of the roller cleaning device 100.

[0061] According to one embodiment of the present invention, the negative pressure chamber 111 has a first end and a second end relatively arranged in the axial direction of the roller 2, the first negative pressure adsorption port 113 is arranged at the first end of the negative pressure chamber 111, and the first liquid supply pipe 114 is arranged at the second end of the negative pressure chamber 111.

[0062] In an embodiment, the first negative pressure adsorption port 113 and the first liquid supply pipe 114 are arranged at both ends of the negative pressure chamber 111, so that the cleaning liquid provided by the first liquid supply pipe 114 can fully contact the inner wall surface of the negative pressure chamber 111, which is conducive to the cleaning liquid cleaning the inner wall surface of the negative pressure chamber 111.

[0063] In some embodiments of the present invention, a liquid distribution pipe 115 is provided on the side of the negative pressure adsorption hood 11 close to the installation space. The liquid distribution pipe 115 extends along the axial direction of the roller 2. The position of the liquid distribution pipe 115 and the adsorption hole 112 are staggered. The outer peripheral surface of the liquid distribution pipe 115 is provided with multiple liquid outlet holes, which are suitable for flowing out cleaning liquid to flush dirt that falls on the liquid distribution pipe 115.

[0064] In other words, the dirt brushed off by the flexible brush roll 13, in addition to being directly sucked away by the adsorption holes 112, will also fall on the areas where the adsorption holes 112 are not provided. The long-term accumulation of dirt will affect the cleaning effect of the spraying and brushing module 10.

[0065] Based on this, as Figure 2 and Figure 3 shown, on the side of the negative pressure adsorption cover 11 close to the installation space, a liquid distribution pipe 115 extending along the axial direction of the rolling roll 2 is provided. The liquid distribution pipe 115 is located in the area of the negative pressure adsorption cover 11 where the adsorption holes 112 are not provided, and a plurality of liquid outlet holes are provided on the outer peripheral surface of the liquid distribution pipe 115. One end of the liquid distribution pipe 115 is provided with an opening and is connected to a liquid supply pipeline (for example, the second liquid supply pipe 117). During use, the cleaning liquid in the liquid distribution pipe 115 can flow out from the liquid outlet holes, so as to wash the dirt falling on the liquid distribution pipe 115, causing the dirt to fall off from the liquid distribution pipe 115. The adsorption holes 112 can suck away the fallen dirt, thereby ensuring the cleaning effect of the spraying and brushing module 10.

[0066] According to an embodiment of the present invention, at least one blocking strip 116 is provided on the side of the negative pressure adsorption cover 11 close to the installation space, and the blocking strip 116 is adapted to knock off the dirt on the bristles.

[0067] Specifically, a plurality of blocking strips 116 are fixedly connected to the side of the negative pressure adsorption cover 11 close to the installation space. The plurality of blocking strips 116 are spaced apart along the circumferential direction of the flexible brush roll 13 and extend along the axial direction of the flexible brush roll 13. The blocking strips 116 can extend into the bristles of the flexible brush roll 13. When the flexible brush roll 13 rotates, the blocking strips 116 can knock off the dirt on the bristles, and the adsorption holes 112 can suck away the knocked-off dirt, thereby ensuring the cleaning effect of the flexible brush roll 13 on the rolling roll 2.

[0068] In some embodiments of the present invention, the residual liquid adsorption module 20 includes: a first negative pressure liquid suction member 21 and a liquid suction roll 22. The first negative pressure liquid suction member 21 is provided on the frame 1, and the first negative pressure liquid suction member 21 is adapted to adsorb the cleaning liquid on the outer peripheral surface of the rolling roll 2. The liquid suction roll 22 is located on the side of the first negative pressure liquid suction member 21 away from the spraying and brushing module 10. The liquid suction roll 22 is rotatably provided on the frame 1 around its own axis, and the outer peripheral surface of the liquid suction roll 22 is attached to the outer peripheral surface of the rolling roll 2 to adsorb the cleaning liquid on the outer peripheral surface of the rolling roll 2.

[0069] In other words, as Figure 1As shown, the residual liquid adsorption module 20 according to an embodiment of the present utility model mainly includes a first negative pressure liquid suction member 21 and a liquid suction roller 22. In the circumferential direction of the rolling roller 2, the first negative pressure liquid suction member 21 is located on the side of the liquid suction roller 22 close to the spraying and brushing module 10. The first negative pressure liquid suction member 21 is fixed to the machine frame 1, and the position of the first negative pressure liquid suction member 21 corresponds to the position of the rolling roller 2. After the outer peripheral surface of the rolling roller 2 is cleaned by the spraying and brushing module 10, the first negative pressure liquid suction member 21 can adsorb the cleaning liquid remaining on the outer peripheral surface of the rolling roller 2; the liquid suction roller 22 extends along the axial direction of the rolling roller 2, and the liquid suction roller 22 is rotatably mounted on the machine frame 1 along its own axis, and the outer peripheral surface of the liquid suction roller 22 is attached to the outer peripheral surface of the rolling roller 2, so that the liquid suction roller 22 can be driven to rotate when the rolling roller 2 rotates, and the liquid suction roller 22 can adsorb the cleaning liquid remaining on the outer peripheral surface of the rolling roller 2 when it rotates.

[0070] In this embodiment, the liquid suction roller 22 is located on the side of the first negative pressure liquid suction member 21 away from the spraying and brushing module 10. The liquid suction roller 22 can further process the outer peripheral surface of the rolling roller 2 after the first negative pressure liquid suction member 21 adsorbs the residual liquid, which can further ensure the dryness of the outer peripheral surface of the rolling roller 2, thereby ensuring the quality of the product.

[0072] In this embodiment, a sponge roller can be used as the liquid suction roller 22. The sponge roller is detachably and rotatably provided on the machine frame 1 by means of clamping or the like. During use, the sponge roller can be replaced according to the water content of the sponge roller. The removed sponge roller can be reused after drying, thereby effectively reducing the cleaning cost of the rolling roller 2.

[0073] It should be noted that when the liquid suction speed of the sponge roller is less than or equal to the evaporation speed of the cleaning liquid, there is no need to replace the sponge roller, and this embodiment will not be elaborated.

[0074] In some embodiments of the present utility model, the machine frame 1 includes: an outer housing 30, the spraying and brushing module 10 is arranged inside the outer housing 30, one side of the outer housing 30 is defined with an avoidance opening 31, the avoidance opening 31 is adapted to accommodate a part of the rolling roller 2, and the outer housing 30 is adapted to block the splashing dirt and / or cleaning liquid.

[0075] That is to say, the rolling roller cleaning device 100 may generate splashing dirt and / or cleaning liquid when cleaning the rolling roller 2. Based on this, as Figure 1 and Figure 4As shown, in this embodiment, at least a part of the frame 1 is configured as an outer housing 30.

Moreover, the outer housing 30 can block the splashing dirt and / or cleaning liquid, thereby effectively avoiding the pollution of the environment by the splashing dirt and / or cleaning liquid.

[0076] In some alternative examples of the present utility model, the frame 1 may further include components of the sub-structure in the pressure roll device where the rolling roll cleaning device 100 can be installed, which will not be elaborated in this embodiment.

[0079] Optionally, the bottom of the outer housing 30 is formed into a funnel structure.

[0080] In some embodiments of the present utility model, the rolling roll cleaning device 100 further includes: a second negative pressure liquid suction member 40. The second negative pressure liquid suction member 40 is provided inside the outer housing 30. The second negative pressure liquid suction member 40 is located on the side of the spraying and brushing module 10 away from the residual liquid adsorption module 20, and the second negative pressure liquid suction member 40 is suitable for adsorbing the cleaning liquid on the outer peripheral surface of the rolling roll 2.

[0081] If the amount of cleaning liquid sprayed by the spraying and brushing module 10 is too small, the cleaning effect of the spraying and brushing module 10 will be affected. If the amount of cleaning liquid sprayed by the spraying and brushing module 10 is too much, the cleaning liquid will flow to the product rolled by the rolling roll 2.

[0082] Based on this, as Figure 1 shown, a second negative pressure liquid suction member 40 is provided inside the outer housing 30. The second negative pressure liquid suction member 40 is located on the side of the spraying and brushing module 10 away from the residual liquid adsorption module 20. Thus, when the amount of cleaning liquid sprayed by the spraying and brushing module 10 is too much, the second negative pressure liquid suction member 40 can be used to adsorb the cleaning liquid, and further, the cleaning liquid can be prevented from flowing to the product, and the product can be prevented from being damaged.

[0083] According to an embodiment of the present utility model, the first negative pressure liquid suction member 21 and the second negative pressure liquid suction member 40 respectively include: a housing 41 and an elastic water blocking portion 42. The housing 41 is disposed on the frame 1. A first opening is provided on one side of the housing 41 close to the roller 2. The elastic water blocking portion 42 is disposed inside the housing 41. The elastic water blocking portion 42 is adapted to be in contact with the outer peripheral surface of the roller 2. A negative pressure adsorption cavity 43 is defined between the wall surface of the elastic water blocking portion 42 close to the brushing module 10 and the inner wall surface of the housing 41. A second opening is provided on one side of the negative pressure adsorption cavity 43 close to the roller 2. The housing 41 is provided with a third negative pressure adsorption port, and the third negative pressure adsorption port is communicated with the negative pressure adsorption cavity 43.

[0084] In other words, the structures of the first negative pressure liquid suction member 21 and the second negative pressure liquid suction member 40 may be the same or different. In this embodiment, the structures of the first negative pressure liquid suction member 21 and the second negative pressure liquid suction member 40 are the same. Hereinafter, the second negative pressure liquid suction member 40 will be taken as an example for specific description.

[0085] As Figure 5 shown, the second negative pressure liquid suction member 40 mainly includes a housing 41 and an elastic water blocking portion 42. Among them, the length of the housing 41 is substantially the same as the length of the roller 2. The housing 41 is fixedly connected to the frame 1. A first opening is provided on one side of the housing 41 close to the roller 2. A part of the elastic water blocking portion 42 can be installed inside the housing 41 through the first opening. The surface of the elastic water blocking portion 42 away from the housing 41 is in close contact with the outer peripheral surface of the roller 2. Thus, the cleaning liquid can be blocked by the elastic water blocking portion 42, and the cleaning liquid can be prevented from flowing to the product. Moreover, in the circumferential direction of the roller 2, a negative pressure adsorption cavity 43 is defined between the side of the elastic water blocking portion 42 close to the brushing module 10 and the inner wall surface of the housing 41. The remaining surface of the elastic water blocking portion 42 is in contact with the inner wall surface of the housing 41. The part of the first opening not blocked by the elastic water blocking portion 42 serves as the second opening of the negative pressure adsorption cavity 43.

[0086] In this embodiment, a third negative pressure adsorption port communicated with the negative pressure adsorption cavity 43 is provided on one side of the housing 41. During use, the third negative pressure adsorption port is connected to a negative pressure generating device, so that a negative pressure can be generated in the negative pressure adsorption cavity 43, so that the cleaning liquid on the outer peripheral surface of the roller 2 can be sucked away from the second opening, and further, the product can be prevented from being damaged by the cleaning liquid.

[0087] In this example, the elastic water blocking portion 42 of the second negative pressure liquid suction member 40 is in contact with the outer peripheral surface of the roller 2. When the roller 2 rotates towards the second negative pressure liquid suction member 40, the side of the elastic water blocking portion 42 away from the brushing module 10 can initially scrape off the toner on the outer peripheral surface of the roller 2, which is beneficial to cleaning the toner thoroughly subsequently. Moreover, the scraped-off toner is adsorbed and collected by the outer cover 30, so that the toner can be prevented from overflowing, and the production quality of the product can be ensured.

[0088] Optionally, the elastic water retaining part 42 is configured as a trapezoidal rubber block or a trapezoidal silica gel block.

[0090] Furthermore, the roll cleaning system according to the embodiment of the present invention further includes a filtration and sedimentation device. For example, the filtration and sedimentation device may include a filter and a sedimentation tank, so that the filtration and sedimentation device can filter and sediment the carbohydrate mixture (i.e., the used cleaning liquid) collected by negative pressure through the roll cleaning device 100. After filtration and sedimentation treatment, the reusable cleaning liquid can be obtained, which can be transported into the corresponding pipeline by using a water pump. Thus, the recycling of the cleaning liquid can be realized, and the cleaning cost of the roll 2 can be effectively reduced.
