Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a roller cleaning device and a roller pressing device. Background Art

[0002] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in areas such as energy storage.

[0003] In the production and manufacturing process of batteries, rolling the electrode sheet is one of the important production processes. In this process, rollers are needed to roll the electrode sheet material to produce battery electrode sheets that meet the requirements. However, the electrode sheet material is easy to adhere to the surface of the roller, affecting the quality of the subsequent rolled electrode sheets. How to reduce the impact of the electrode sheet material adhering to the roller on the electrode sheet production is one of the research topics in the industry. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a roller cleaning device and a roller pressing equipment which can clean the surface of the roller while the roller is working.

[0005] In the first aspect, an embodiment of the present application provides a roller cleaning device, comprising: a wetting mechanism for spraying cleaning liquid onto the outer peripheral surface of the roller; a scraping mechanism for scraping the cleaning liquid on the outer peripheral surface of the roller, wherein the scraping mechanism is located on the downstream side of the wetting mechanism along the rotation direction of the roller; and a wiping mechanism for wiping the outer peripheral surface of the roller, wherein the wiping mechanism is located on the downstream side of the scraping mechanism along the rotation direction of the roller; wherein the wiping mechanism comprises an unwinding assembly for unwinding the wiping piece and a winding assembly for winding the wiping piece, wherein when the unwinding assembly unwinds the wiping piece, the winding assembly can rotate under the friction between the unwinding wiping piece and the outer peripheral surface of the roller, thereby winding up the wiping piece.

[0006] In the embodiment of the present application, since a soaking mechanism is provided, the cleaning liquid sprayed by the soaking mechanism can soften or even dissolve the stains on the outer peripheral surface of the roller, which helps to reduce the adhesion of the stains. Since a scraping mechanism for scraping the outer peripheral surface of the roller is provided on the downstream side of the soaking mechanism, the stains can be scraped off by the scraping mechanism, and at least part of the cleaning liquid carrying the stains can be scraped off. Since the wiping mechanism is provided at the most downstream position, the stains on the outer peripheral surface of the roller can be wiped off by the wiping mechanism after soaking and scraping, and the cleaning liquid remaining on the roller can be adsorbed, further reducing the residue on the surface of the roller.

[0007] In addition, since the winding assembly can rotate under the action of the friction between the wiping member and the outer peripheral surface of the roller, when replacing the wiping member, it is only necessary to control the unwinding assembly to unwind, and there is no need to set up an additional driving device to drive the winding assembly to rotate, which reduces the number of mechanism parts and components, reduces the development cost of the overall device, and also helps to save energy and simplify the control method. Moreover, since the various mechanisms of the roller cleaning device operate while the roller rotates, the cleaning of the roller can be carried out simultaneously when the roller is operating, which helps to improve the quality of the products pressed out by the roller and improve production efficiency.

[0008] In some embodiments, the wiping mechanism also includes a wiping frame, the winding assembly includes a first abutment shaft for abutting the wiping member against the outer peripheral surface of the roller, a winding shaft for winding the wiping member, and a transmission member connecting the first abutment shaft and the winding shaft, and the first abutment shaft and the winding shaft are respectively rotatably connected to the wiping frame; wherein, when the unwinding assembly unwinds the wiping member, the first abutment shaft can rotate under the friction between the unwinding wiping member and the outer peripheral surface of the roller, thereby driving the winding shaft to rotate.

[0009] Thus, the first abutting shaft abuts the wiping member against the roller, so that the wiping member can better wipe the stains on the roller and absorb the liquid thereon. When the wiping member is unwound, the wiping member can move with the rotation of the roller and drive the first abutting shaft to rotate. The first abutting shaft drives the reeling shaft to rotate through the transmission member, thereby reeling in the unwound wiping member, thereby realizing automatic reeling of the wiping member, with a simple structure and ingenious design.

[0010] In some embodiments, a diameter of the first abutment shaft is less than or equal to a diameter of the take-up shaft.

[0011] Therefore, when the winding assembly is working and the first abutment shaft and the winding shaft are rotating, the moving path of the wiping member wound up by the winding shaft is longer than the moving path of the wiping member driven by the first abutment shaft, so that the wiping member can remain in a tensioned state and better clean the surface of the roller.

[0012] In some embodiments, the transmission member includes a first transmission wheel, a second transmission wheel and a transmission belt, the first abutment shaft is connected to the first transmission wheel, the winding shaft is connected to the second transmission wheel, and the transmission belt surrounds the first transmission wheel and the second transmission wheel, so that the first transmission wheel and the second transmission wheel rotate synchronously.

[0013] Thus, the first abutment shaft and the winding shaft can be rotated synchronously through the cooperation of the first transmission wheel, the second transmission wheel and the transmission belt.

[0014] In some embodiments, the winding shaft is connected to the second transmission wheel via a damper, and when the resistance applied to the winding shaft is greater than a preset resistance of the damper, the winding shaft stops rotating.

[0015] Therefore, when the resistance to the winding shaft is too great, the damper can block the synchronous rotation of the winding shaft and the second transmission wheel, thereby reducing the possibility of damage to the wiping member due to excessive tension and improving the reliability of the winding assembly.

[0016] In some embodiments, the unwinding assembly includes a power assembly, an unwinding shaft wound with the wiping piece, and a second abutment shaft for abutting the wiping piece against the outer circumferential surface of the roller, the second abutment shaft and the first abutment shaft are arranged at intervals along a first direction; the unwinding shaft and the second abutment shaft are respectively rotatably connected to the wiping frame, and the unwinding shaft can rotate under the drive of the power assembly to unwind the wiping piece; wherein the first direction is the height direction of the wiping frame.

[0017] Thus, the first abutting shaft and the second abutting shaft can spread the wiping member from both sides, so that the wiping member can provide a larger wiping surface to the roller, which helps to improve the wiping effect. The unwinding of the unwinding shaft can be controlled in an automated manner through the power assembly, which is conducive to saving labor costs.

[0018] In some embodiments, the wiping frame includes a fixed frame, a movable frame and a first cylinder, the first cylinder is arranged on the fixed frame, and the telescopic end of the first cylinder is connected to the movable frame; the unwinding shaft and the winding shaft are connected to the fixed frame, the first abutment shaft and the second abutment shaft are connected to the movable frame, and the movable frame can reciprocate along a second direction intersecting with the first direction under the drive of the first cylinder.

[0019] Therefore, the movable frame can be moved in the second direction by driving the first cylinder, thereby changing the distance between the first abutment shaft and the second abutment shaft relative to the roller. Regardless of the size of the roller, the first abutment shaft and the second abutment shaft can be fitted to the outer circumferential surface of the roller, so that the wiping member can be fitted to the outer circumferential surface of the roller, and the compatibility is better.

[0020] In some embodiments, the transmission member includes a transmission belt, the winding assembly also includes a tensioning assembly, the first abutment shaft, the winding shaft and the tensioning assembly are connected via the transmission belt, and the tensioning assembly is configured to keep the transmission belt in a tensioned state.

[0021] Therefore, when the position of the movable frame changes along the second direction, the tensioning assembly can always maintain the tensioned state of the transmission belt, so that the first abutment shaft and the winding shaft can rotate synchronously, which helps to improve the reliability of the automatic winding function.

[0022] In some embodiments, the tensioning assembly includes a slider, a first elastic member and a rotating wheel; a slide groove extending along the first direction is opened on the movable frame, and the slider is arranged in the slide groove in a manner that it can slide in the slide groove, and the first elastic member is located on the side of the slide groove close to the winding shaft along the first direction, and one end of the first elastic member abuts the slider, and the other end abuts the groove wall of the slide groove, the rotating wheel is connected to the slider, and the first abutting shaft, the winding shaft and the rotating wheel are connected through the transmission belt.

[0023] Thus, the first elastic member provides a force to the slider in a direction away from the winding shaft, so that the rotating wheel on the slider provides a force to the transmission belt in a direction away from the winding shaft, thereby keeping the transmission belt in a tensioned state, which helps to improve the reliability of the automatic winding function.

[0024] In some embodiments, the power assembly includes a first gear coaxially connected to the unwinding shaft, a rack meshing with the first gear, and a second cylinder; the second cylinder is arranged on the wiping frame, and the telescopic end of the second cylinder is connected to the rack, and the rack can reciprocate under the drive of the second cylinder, thereby driving the first gear and the unwinding shaft coaxially connected to the first gear to rotate.

[0025] Thus, the second cylinder can provide stable and easily controllable power, so that the rack moves smoothly and controllably. Since the rack is meshed with the first gear, and the first gear is coaxially connected to the unwinding shaft, the first gear can rotate with the movement of the rack, so that the horizontal movement can be converted into rotation, and then the unwinding shaft can be rotated, so that the wiping piece to be replaced leaves the position of abutting the roller, and the clean wiping piece abuts the roller for wiping.

[0026] In some embodiments, the first gear and the unwinding shaft are coaxially connected via a one-way bearing, and the one-way bearing is configured to enable the unwinding shaft to rotate together with the first gear when the first gear rotates along the unwinding direction, and to enable the unwinding shaft to remain stationary when the first gear rotates in a direction opposite to the unwinding direction.

[0027] Thus, the unwinding shaft will only rotate along the unwinding direction, so that the unwinding shaft will only unwind the wiping member, and will not rewind the unwound wiping member to be replaced, thereby continuously providing clean wiping members to the roller.

[0028] In some embodiments, the one-way bearing includes a bearing outer ring and a bearing inner ring, the first gear is connected to the bearing outer ring, and the unwinding shaft is connected to the bearing inner ring; when the first gear rotates along the unwinding direction, the bearing inner ring is fixed relative to the bearing outer ring, and when the first gear rotates in a direction opposite to the unwinding direction, the bearing inner ring rotates relative to the bearing outer ring.

[0029] As a result, the unwinding shaft can only rotate along the unwinding direction, so that the wiping member wound thereon can move in one direction, thereby continuously providing clean wiping members to the roller.

[0030] In some embodiments, the cross section of the unwinding shaft is polygonal, and the unwinding shaft is engaged and connected to the inner ring of the bearing, and the cross section is perpendicular to the extension direction of the unwinding shaft.

[0031] Thus, the unwinding shaft can be engaged with the inner ring of the bearing and rotate synchronously with the inner ring of the bearing, and the two are not prone to relative rotation with each other, which is beneficial to improving the unwinding reliability.

[0032] In some embodiments, the reel-up shaft is detachably connected to the wiping frame, and the unreeling shaft is detachably connected to the wiping frame.

[0033] As a result, it is easier to replace the wiping piece. When the wiping piece on the unwinding shaft is used up or you want to replace it with another type of wiping piece, you can remove the unwinding shaft and the winding shaft, take out the wiping piece to be replaced, and replace it with a new one. The replacement operation is simple, which is conducive to improving replacement efficiency.

[0034] In some embodiments, a second elastic member is formed on the shaft wall of the unwinding shaft, and the second elastic member can undergo elastic deformation under the action of external force. When the reel wound with the wiping member is sleeved on the unwinding shaft, the second elastic member abuts against the inner wall of the reel.

[0035] Thus, the position of the reel relative to the unwinding shaft is fixed, and when the unwinding shaft is unwinding, the reel can rotate synchronously with the unwinding shaft. Moreover, the reel can be taken out of or inserted into the unwinding shaft by applying an external force greater than the second elastic member, so that the position of the reel relative to the unwinding shaft can be adjusted, and a new wiping member and a reel wound with the wiping member can be replaced, which is flexible and convenient to use.

[0036] In some embodiments, the winding shaft is provided with a pressing block, and the pressing block is used to press the wiping member onto the surface of the winding shaft, and the pressing block is detachably connected to the winding shaft via a threaded member.

[0037] Therefore, it is convenient to install and remove the wiping piece on the winding shaft, and the distance between the pressing block and the winding shaft can be adjusted by rotating the screw member. The distance can be reduced so that the pressing block can press the wiping piece tightly on the surface of the winding shaft, and the distance can be increased to loosen the wiping piece. The structure is simple and easy to use.

[0038] In some embodiments, the roller cleaning device also includes a support frame, the wiping mechanism is arranged on the support frame in a manner that it can rotate between a working position and a replacement position, a first matching piece is provided on the support frame, and a second matching piece is provided on the wiping mechanism; wherein, in the working position, the second matching piece is connected with the first matching piece in a matching manner.

[0039] Thus, the wiping mechanism can wipe the roller when it is in the working position. The wiping mechanism is away from the roller when changing positions, thereby reducing the impact on the roller operation when replacing the wiping member or maintaining the wiping mechanism. The wiping member can be replaced without affecting the roller operation, which helps to improve production efficiency.

[0040] In some embodiments, the first mating piece can be switched between a first posture and a second posture by rotating. When the first mating piece is in the first posture, the first mating piece is locked with the second mating piece. When the first mating piece is in the second posture, the first mating piece is unlocked with the second mating piece.

[0041] Therefore, the wiping mechanism can be fixed on the support frame or released from the support frame by rotating the first matching piece, thereby changing the position of the wiping mechanism, with a simple structure and ingenious design.

[0042] In some embodiments, the roller cleaning device also includes a support frame, and the scraping mechanism is arranged on the support frame; the scraping mechanism includes a scraping assembly and a third cylinder, and the scraping assembly can rotate relative to the support frame; the telescopic end of the third cylinder is connected to the scraping assembly, and the scraping assembly can rotate toward or away from the outer circumferential surface of the roller under the drive of the third cylinder.

[0043] Therefore, when performing scraping operations, the third cylinder can drive the scraping assembly to rotate, thereby changing the angle of the scraping assembly relative to the roller, so that the scraping assembly can abut the outer circumferential surface of the roller, and for rollers of different sizes, the scraping assembly can be driven by the third cylinder to abut the outer circumferential surface of the roller, thereby performing a good scraping operation and having better compatibility.

[0044] In some embodiments, a first limit member is provided on the support frame, and a second limit member is provided on the scraping assembly; the second limit member protrudes from the surface of the scraping assembly, and the first limit member is located on the rotation path of the scraping assembly, and is used to limit the rotation of the scraping assembly through the cooperation of the first limit member and the second limit member.

[0045] Therefore, after the scraper assembly rotates to a certain angle, the second limit member contacts the first limit member and is blocked by the first limit member, thereby limiting the rotation angle of the scraper assembly and maintaining the angle of the scraper assembly relative to the roller within a reasonable range, thereby reducing the possibility of the scraper assembly causing damage to the outer surface of the roller.

[0046] In some embodiments, the scraping assembly includes a scraping frame and a scraper, the scraper is installed on the scraping frame, and the telescopic end of the third cylinder is connected to the scraping frame; the scraping mechanism also includes at least one press-release assembly, and the scraper is detachably installed on the scraping frame through the press-release assembly.

[0047] Therefore, the scraper can be replaced by pressing and releasing the assembly, so that the scraper can meet the scraping requirements and maintain the scraping effect. In addition, the third cylinder can pull the scraper frame away from the roller, so that the scraper can be replaced while the roller is operating normally, without the need to stop the roller and wait, which helps to improve production efficiency.

[0048] In some embodiments, the scraper frame includes a first plate and a second plate facing each other, the pressing and releasing assembly includes a cam and a connecting piece passing through the first plate and the second plate, the cam is rotatably connected to one end of the connecting piece, the scraper is located between the first plate and the second plate, and the cam can switch between a first state and a second state by rotating. When the cam is in the first state, the cam presses the first plate and the second plate; when the cam is in the second state, the cam loosens the first plate and the second plate.

[0049] Therefore, the scraper can be fixed between the first plate and the second plate by rotating the cam, or the scraper can be taken out from between the loosened first plate and the second plate, so that the scraper can be easily disassembled and replaced.

[0050] In some embodiments, the scraping mechanism further includes a water receiving tray, and the water receiving tray is located below the scraping assembly along the direction of gravity.

[0051] Therefore, the liquid scraped by the scraping assembly can be collected in the water receiving tray, which is helpful for the centralized treatment of the liquid and can reduce the impact of the random flow and splashing of the liquid on the working environment of the roller.

[0052] In some embodiments, the scraping mechanism further includes a storage box, and the water receiving tray is connected to the storage box.

[0053] Therefore, the storage box can collect the liquid in the water receiving tray in a centralized manner, which is helpful for the subsequent centralized processing of the liquid, and can also improve the problem of liquid overflowing and splashing from the water receiving tray, and reduce the impact of random flow and splashing of liquid on the working environment of the roller.

[0054] In some embodiments, the wetting mechanism includes a wetting frame and a nozzle capable of spraying the cleaning liquid onto the roller. The nozzle is multiple in number and the multiple nozzles are arranged on the wetting frame at intervals along the extension direction of the wetting frame.

[0055] As a result, the spraying area of ​​multiple nozzles working together can cover a larger area of ​​the roller, which helps to reduce cleaning dead corners and improve the cleaning effect.

[0056] In some embodiments, the roller cleaning device further comprises a support frame; the soaking frame is arranged on the support frame in a manner capable of rotating relative to the support frame.

[0057] Thereby, the angle of the wetting frame relative to the nip roller can be changed, and thus the spraying angle of the nozzle relative to the nip roller can be adjusted.

[0058] In some embodiments, the soaking rack includes a third plate, a fourth plate, a rotating shaft and an adjustable angle bolt. Along the extension direction of the third plate, the fourth plate is located on opposite sides of the third plate. The fourth plate is rotatably connected to the support rack through the rotating shaft, and the nozzle is arranged on the third plate; wherein, the fourth plate is provided with an arc-shaped slide groove, the adjustable angle bolt passes through the arc-shaped slide groove and is threadedly connected to the support rack, and the angle of the adjustable angle bolt relative to the support rack is adjustable.

[0059] Thus, the fourth plate supports the third plate from both sides of the third plate, which helps to improve the firmness of the fourth plate supporting the third plate. The fourth plate can rotate relative to the support frame, and the angle of the third plate and the nozzle disposed thereon can be changed by rotating the fourth plate, so that the nozzle can spray the cleaning liquid at a suitable angle. The position of the third plate with the adjusted angle can be kept unchanged by rotating the adjustable angle bolt.

[0060] In some embodiments, the roller cleaning device includes a protective cover with an opening facing the roller, and the protective cover covers the wetting mechanism.

[0061] Therefore, the protective cover can reduce the possibility of the cleaning liquid sprayed by the immersion mechanism splashing into the surrounding environment, and reduce the impact of liquid dripping on the working environment of the roller.

[0062] A second aspect of the present application provides a rolling device for rolling coated pole pieces, comprising a rolling roller and a rolling roller cleaning device provided in the first aspect and arranged corresponding to the rolling roller.

[0063] As a result, the rollers can be cleaned using a roller cleaning device while the rollers are operating, which helps to improve the quality of the products pressed out by the rollers and improve production efficiency.

[0094] Below, this application is described in detail.

[0095] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in areas such as energy storage.

[0096] In the production and manufacturing process of batteries, rolling the electrode sheet is one of the important production processes. In this process, rollers are needed to roll the electrode sheet material to produce battery electrode sheets that meet the requirements. However, the electrode sheet material is easy to adhere to the surface of the roller, affecting the quality of the subsequent rolled electrode sheets. How to reduce the impact of the electrode sheet material adhering to the roller on the electrode sheet production is one of the research topics in the industry.

[0097] In the related art, after the rollers have been working for a period of time, they will be stopped for cleaning by staff, and then resumed. However, manual cleaning is time-consuming and labor-intensive, slowing down the pace of battery production, and it is difficult to stop the machine immediately after adhesion occurs, which may have a certain impact on the quality of the electrode and may also reduce the production efficiency of battery production.

[0098] The present application hopes to provide a roll cleaning device and a rolling equipment which can clean the surface of the roll while the roll is working.

[0099] Based on such a design concept, the present application proposes a roller cleaning device, including: a wetting mechanism, a scraping mechanism and a wiping structure. The wetting mechanism is used to spray cleaning liquid onto the outer peripheral surface of the roller; the scraping mechanism is used to scrape the cleaning liquid on the outer peripheral surface of the roller, and along the rotation direction of the roller, the scraping mechanism is located on the downstream side of the wetting mechanism; the wiping mechanism is used to wipe the outer peripheral surface of the roller, and along the rotation direction of the roller, the wiping mechanism is located on the downstream side of the scraping mechanism; wherein the wiping mechanism includes an unwinding assembly for unwinding the wiping member and a winding assembly for winding the wiping member, and when the unwinding assembly unwinds the wiping member, the winding assembly can rotate under the friction between the unwinding wiping member and the outer peripheral surface of the roller, thereby winding the wiping member.

[0100] Since the soaking mechanism is provided, the cleaning liquid sprayed by the soaking mechanism can soften or even dissolve the stains on the outer peripheral surface of the roller, which helps to reduce the adhesion of the stains. Since a scraping mechanism is provided on the downstream side of the soaking mechanism to scrape the outer peripheral surface of the roller, the scraping mechanism can scrape off the stains and at least part of the cleaning liquid carrying the stains. Since the wiping mechanism is provided at the most downstream position, the wiping mechanism can wipe off the stains and absorb the cleaning liquid remaining on the roller after soaking and scraping, further reducing the residue on the surface of the roller.

[0101] In addition, since the winding assembly can rotate under the action of the friction between the wiping member and the outer peripheral surface of the roller, when replacing the wiping member, it is only necessary to control the unwinding assembly to unwind, and there is no need to set up an additional driving device to drive the winding assembly to rotate, which reduces the number of mechanism parts and reduces the development cost of the overall device, while also helping to save energy and simplify the control method. Moreover, while the roller rotates, each mechanism operates, so the cleaning of the roller can be carried out simultaneously when the roller is operating, which helps to improve the quality of the product pressed out by the roller and improve production efficiency.

[0102] The roller cleaning device of the embodiment of the present application can be used for rolling equipment, and can also be used for cleaning other equipment with rotatable rollers.

[0103] The rolling device of the embodiment of the present application can be used in the production process of the battery, for example, for rolling the pole piece of the battery, etc. Of course, those skilled in the art should understand that the rolling device provided in the embodiment of the present application is not only used for rolling the pole piece in the production process of the battery, but can also be used for rolling other components that need to be rolled in the production process of the battery.

[0104] The pole piece includes a positive electrode, a negative electrode and a separator, and the separator is arranged between the negative electrode and the positive electrode. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are embedded and released back and forth between the positive electrode and the negative electrode. The separator is arranged between the positive electrode and the negative electrode to prevent the positive and negative electrodes from short-circuiting, while allowing active ions to pass through.

[0105] In some embodiments, the positive electrode may be a positive electrode sheet, and the positive electrode sheet may include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0106] As an example, the positive electrode current collector has two surfaces facing each other in its thickness direction, and the positive electrode active material is disposed on either or both of the two facing surfaces of the positive electrode current collector.

[0107] As an example, the positive electrode current collector may be a metal foil, a conductive polymer material, a carbon material or a composite current collector. For example, as the metal foil, a pure metal, an alloy, a surface-treated metal may be used, including but not limited to stainless steel, copper, aluminum, nickel, nickel, titanium or silver. The composite current collector may include a polymer material base layer and a metal layer.

[0108] In some embodiments, the negative electrode may be a negative electrode sheet, and the negative electrode sheet may include a negative electrode current collector.

[0109] As an example, the negative electrode current collector may be a metal foil, a conductive polymer material, a carbon material or a composite current collector. For example, as the metal foil, a pure metal, an alloy, a surface-treated metal may be used, including but not limited to stainless steel, copper, aluminum, nickel, nickel, titanium or silver. The composite current collector may include a polymer material base layer and a metal layer.

[0110] In some embodiments, the material of the positive electrode current collector may be aluminum, and the material of the negative electrode current collector may be copper.

[0113] In some embodiments of the present application, a first direction is set for ease of description. Figures 1 to 8 As shown, the direction of arrow Z is the first direction, that is, the height direction of the wiping rack. The direction of arrow X is the second direction, which is perpendicular to the first direction.

[0114] like Figure 1As shown, a first aspect of the present application provides a roller cleaning device 2000 , which includes a wetting mechanism 10 , a scraping mechanism 20 and a wiping mechanism 30 . The wetting mechanism 10 is used to spray cleaning liquid onto the outer peripheral surface of the roller 100; the scraping mechanism 20 is used to scrape the cleaning liquid on the outer peripheral surface of the roller 100, and the scraping mechanism 20 is located on the downstream side of the wetting mechanism 10 along the rotation direction of the roller 100; the wiping mechanism 30 is used to wipe the outer peripheral surface of the roller 100, and the wiping mechanism 30 is located on the downstream side of the scraping mechanism 20 along the rotation direction of the roller 100; wherein, the wiping mechanism 30 includes a wiping member 31, an unwinding assembly 32 for unwinding the wiping member 31, and a winding assembly 33 for winding the wiping member 31, and when the unwinding assembly 32 unwinds the wiping member 31, the winding assembly 33 can rotate under the friction between the unwinding wiping member 31 and the outer peripheral surface of the roller 100, thereby winding the wiping member 31.

[0115] The roller cleaning device 2000 is disposed on one side of the roller 100 and faces the outer peripheral surface of the roller 100. The roller 100 may be configured as a cylinder, and the outermost surface along the radial direction of the roller 100 is the outer peripheral surface of the roller 100. The roller 100 rotates around its own axis, and the outer peripheral surface of the roller 100 can cooperate with another surface to compact the material, and the other surface may be the outer peripheral surface of another roller 100.

[0116] The roller cleaning device 2000 comprises a wetting mechanism 10, a scraping mechanism 20 and a wiping mechanism 30. Along the rotation direction of the roller 100, the wetting mechanism 10 is located at the most upstream, the wiping mechanism 30 is located at the most downstream, and the scraping mechanism 20 is located between the wetting mechanism 10 and the wiping mechanism 30.

[0117] As the roller 100 rotates continuously, the outer peripheral surface of the roller 100 first passes through the soaking mechanism 10, and the soaking mechanism 10 sprays the cleaning liquid onto the outer peripheral surface of the roller 100 facing it. The cleaning liquid adheres to the outer peripheral surface of the roller 100 and is driven to the scraping mechanism 20 as the roller 100 rotates, and is scraped by the scraping mechanism 20. The outer peripheral surface of the roller 100 scraped by the scraping mechanism 20 then passes through the wiping mechanism 30, and is wiped by the wiping mechanism 30, completing the entire cleaning operation.

[0118] The wetting mechanism 10 is a mechanism for spraying cleaning liquid onto the outer peripheral surface of the roller 100. The wetting mechanism 10 can be connected to a liquid supply tank storing cleaning liquid through a pipeline, and the wetting mechanism 10 can spray the cleaning liquid in the liquid supply tank onto the roller 100.

[0119] The scraping mechanism 20 is a mechanism for scraping off the cleaning liquid on the outer peripheral surface of the roller 100. The scraping mechanism 20 includes at least a scraper 212 that contacts the roller 100.

[0120] The wiping mechanism 30 is a mechanism for wiping the outer peripheral surface of the roller 100. The wiping mechanism 30 has at least a wiping member 31 that abuts against the roller 100, and the wiping member 31 absorbs the cleaning liquid remaining on the roller 100 and removes the foreign matter on the surface of the roller 100.

[0121] Next, the structure of the wiping mechanism 30 will be described in detail.

[0122] In the embodiment of the present application, the wiping mechanism 30 includes an unwinding assembly 32 and a winding assembly 33, and the outer peripheral surfaces of the unwinding assembly 32 and the winding assembly 33 are used to carry the wiping member 31. Along the rotation direction of the roller 100, the unwinding assembly 32 is located on the upstream side of the winding assembly 33. Part of the wiping member 31 is wound on the unwinding assembly 32, and part of the wiping member 31 is wound on the winding assembly 33. The part of the wiping member 31 located between the unwinding assembly 32 and the winding assembly 33 can abut against the outer peripheral surface of the roller 100, thereby wiping the outer peripheral surface of the roller 100.

[0123] When the roller 100 rotates, the wiping member 31 tends to be driven by the roller 100 and move from the unwinding assembly 32 to the winding assembly 33. When the unwinding assembly 32 unwinds part of the wiping member 31, the portion of the wiping member 31 between the unwinding assembly 32 and the winding assembly 33 has redundancy, so that the wiping member 31 can move toward the winding assembly 33 under the friction of the roller 100, and the winding assembly 33 can be driven to rotate by the movement of the wiping member 31, thereby winding up the redundant amount of the wiping member 31.

[0124] The wiping member 31 is a flexible member with a certain degree of surface roughness and capable of absorbing liquid. For example, the wiping member 31 can be linen, fiber cloth, nylon cloth, flannel, etc. The embodiment of the present application does not specifically limit the type of the wiping member 31, as long as it can wipe and clean the outer peripheral surface of the roller 100.

[0125] The unwinding component 32 is a component that can wind up the wiping member 31 and release a part of the wiping member 31 from its winding state by rotating in the unwinding direction.

[0126] The winding assembly 33 is an assembly capable of fixing and winding the wiping member 31 .

[0127] In the embodiment of the present application, since the soaking mechanism 10 is provided, the cleaning liquid sprayed by the soaking mechanism 10 can soften or even dissolve the stains on the outer peripheral surface of the roller 100, which helps to reduce the adhesion of the stains. Since a scraping mechanism 20 is provided on the downstream side of the soaking mechanism 10 to scrape the outer peripheral surface of the roller 100, the scraping mechanism 20 can scrape off the stains, and at least part of the cleaning liquid carrying the stains can also be scraped off. Since the wiping mechanism 30 is provided at the most downstream position, the wiping mechanism can wipe off the stains and absorb the cleaning liquid remaining on the roller 100 after soaking and scraping, further reducing the residue on the surface of the roller 100.

[0128] In addition, since the winding assembly 33 can rotate under the friction between the wiping member 31 and the outer peripheral surface of the roller 100, when replacing the wiping member 31, it is only necessary to control the unwinding assembly 32 to unwind, and there is no need to set up an additional driving device to drive the winding assembly 33 to rotate, which reduces the number of mechanical parts and components, reduces the development cost of the overall device, and also helps to save energy and simplify the control method. Moreover, since the various mechanisms of the roller cleaning device 2000 operate while the roller 100 rotates, the cleaning of the roller 100 can be carried out simultaneously when the roller 100 operates, which helps to improve the quality of the products pressed out by the roller and improve production efficiency.

[0129] In some embodiments of the present application, Figures 2 to 4 As shown, the wiping mechanism 30 also includes a wiping frame 34, and the winding assembly 33 includes a first abutment shaft 331 for abutting the wiping member 31 against the outer peripheral surface of the roller 100, a winding shaft 332 for winding the wiping member 31, and a transmission member 333 for connecting the first abutment shaft 331 and the winding shaft 332, and the first abutment shaft 331 and the winding shaft 332 are respectively rotatably connected to the wiping frame 34; wherein, when the unwinding assembly 32 unwinds the wiping member 31, the first abutment shaft 331 can rotate under the friction between the unwinding wiping member 31 and the outer peripheral surface of the roller 100, thereby driving the winding shaft 332 to rotate.

[0130] The wiping mechanism 30 further includes a wiping frame 34. The wiping frame 34 is used to carry various components for realizing the functions of the wiping mechanism 30. For example, the winding assembly 33 and the unwinding assembly 32 can be arranged on the wiping member 31, and can be installed on an external support surface through the wiping frame 34. The wiping frame 34 can be a frame body or a plate-like body. The present application does not impose any special restrictions on the specific structure of the wiping frame 34.

[0131] like Figure 6As shown, the winding assembly 33 includes a first abutting shaft 331, a winding shaft 332 and a transmission member 333. The first abutting shaft 331 is rotatably connected to the wiping frame 34 and can abut against the roller 100. The winding shaft 332 is rotatably connected to the wiping frame 34, and the winding shaft 332 can be connected to the wiping member 31. When the winding shaft 332 rotates, the wiping member 31 can be wound on its radial surface. Part of the wiping member 31 is wound on the unwinding assembly 32, and part of the wiping member 31 is wound on the winding shaft 332. The part of the wiping member 31 located in the unwinding assembly 32 and the winding shaft 332 passes through the first abutting shaft 331 and covers the side of the first abutting shaft 331 facing the roller 100. The transmission member 333 is transmission-connected to the first abutting shaft 331 and the winding shaft 332, so that the first abutting shaft 331 and the winding shaft 332 can rotate simultaneously.

[0132] When the unwinding assembly 32 unwinds part of the wiping member 31, the part of the wiping member 31 between the unwinding assembly 32 and the winding shaft 332 has a redundant amount, so that the wiping member 31 can move toward the winding shaft 332 under the friction of the roller 100. The first abutting shaft 331 is driven to rotate under the friction of the wiping member 31, and the transmission member 333 transmits the rotation of the first abutting shaft 331 to the winding shaft 332, so that the winding shaft 332 rotates, thereby winding up the redundant amount of the wiping member 31.

[0133] Specifically, the wiping frame 34 has two installation surfaces spaced apart from each other, and the winding assembly 33 is arranged between the two installation surfaces. The two ends of the first abutting shaft 331 are rotatably connected to the two installation surfaces respectively, and the two ends of the winding shaft 332 are rotatably connected to the two installation surfaces respectively. The extension direction of the first abutting shaft 331 is parallel to the extension direction of the winding shaft 332. The first abutting shaft 331 and the winding shaft 332 are spaced apart from each other. The first abutting shaft 331 and the winding shaft 332 rotate together under the drive of the transmission member 333.

[0134] Exemplarily, the transmission member 333 may include a transmission structure such as a chain, a transmission belt 3333, a gear set, etc.

[0135] Thus, the first abutting shaft 331 abuts the wiping member 31 against the roller 100, so that the wiping member 31 can better wipe the stains on the roller 100 and absorb the liquid thereon. When the wiping member 31 is unwound, the wiping member 31 can move with the rotation of the roller 100, and drive the first abutting shaft 331 to rotate. The first abutting shaft 331 drives the reeling shaft 332 to rotate through the transmission member 333, so as to reel in the unwound wiping member 31, thereby realizing the automatic reeling of the wiping member 31. The structure is simple and the design is ingenious. In addition, the reeling assembly 33 does not need to be provided with an additional driving device, which is conducive to reducing the number of parts, reducing the device cost, and also conducive to energy saving and environmental protection.

[0136] In some embodiments of the present application, the diameter of the first abutting shaft 331 is smaller than or equal to the diameter of the winding shaft 332 .

[0137] The transmission member 333 is configured to drive the first contact shaft 331 and the winding shaft 332 to rotate at the same rotation angle.

[0138] Therefore, when the winding assembly 33 is working and the first abutment shaft 331 and the winding shaft 332 are rotating, the moving path of the wiping member 31 wound up by the winding shaft 332 is longer than the moving path of the wiping member 31 driven by the first abutment shaft 331, so that the wiping member 31 can maintain a tensioned state and better clean the surface of the roller.

[0139] In some embodiments of the present application, Figure 4 As shown, the transmission member 333 includes a first transmission wheel 3331, a second transmission wheel 3332 and a transmission belt 3333, the first abutment shaft 331 is connected to the first transmission wheel 3331, the winding shaft 332 is connected to the second transmission wheel 3332, and the transmission belt 3333 surrounds the first transmission wheel 3331 and the second transmission wheel 3332, so that the first transmission wheel 3331 and the second transmission wheel 3332 rotate synchronously.

[0140] The transmission member 333 includes a first transmission wheel 3331, a second transmission wheel 3332 and a transmission belt 3333. The first transmission wheel 3331 is coaxially connected to the first abutting shaft 331, the second transmission wheel 3332 is coaxially connected to the winding shaft 332, and the transmission belt 3333 surrounds the first transmission wheel 3331 and the second transmission wheel 3332.

[0141] Specifically, both ends of the first abutting shaft 331 penetrate the wiping frame 34, and at least one end of the first abutting shaft 331 is coaxially connected to the first transmission wheel 3331. Both ends of the winding shaft 332 penetrate the wiping frame 34, and at least one end of the winding shaft 332 is coaxially connected to the second transmission wheel 3332. The transmission belt 3333 surrounds the first transmission wheel 3331 and the second transmission wheel 3332, so that the first abutting shaft 331 and the winding shaft 332 can rotate synchronously through the cooperation of the first transmission wheel 3331, the second transmission wheel 3332 and the transmission belt 3333.

[0142] Exemplarily, the diameters of the first transmission wheel 3331 and the second transmission wheel 3332 are the same, so that the first transmission wheel 3331 and the second transmission wheel 3332 rotate at the same rotation angle, thereby making the first abutting shaft 331 and the winding shaft 332 rotate in the same direction at the same rotation angle.

[0143] Exemplarily, the transmission belt 3333 may be made of an elastic material.

[0144] In some other embodiments, the transmission member 333 may also be a gear transmission member, including a second gear and a third gear. The second gear and the third gear are meshed, the second gear and the first transmission wheel 3331 are coaxially connected, and the third gear and the winding shaft 332 are coaxially connected. Further, the transmission member 333 may also include a fifth gear, which is located between the second gear and the third gear and is meshed with the second gear and the third gear respectively.

[0145] In some embodiments of the present application, the winding shaft 332 is connected to the second transmission wheel 3332 via a damper, and when the resistance encountered by the winding shaft 332 is greater than the preset resistance of the damper, the winding shaft 332 stops rotating.

[0146] A damper is a device that provides a force to resist motion and consumes the energy of motion.

[0147] Therefore, when the resistance encountered by the winding shaft 332 is too great, that is, when the speed at which the winding shaft 332 winds up the wiping element 31 is much greater than the supply speed of the wiping element 31, the damper can block the synchronous rotation of the winding shaft 332 and the second transmission wheel 3332, thereby reducing the possibility of damage to the wiping element 31 due to excessive tension, and improving the reliability of the winding assembly 33.

[0148] In some embodiments of the present application, Figure 6 As shown, the unwinding assembly 32 includes a power assembly 321, an unwinding shaft 322 wound with the wiping element 31, and a second abutting shaft 323 for abutting the wiping element 31 against the outer peripheral surface of the roller 100, and the second abutting shaft 323 and the first abutting shaft 331 are arranged at intervals along the first direction Z; the unwinding shaft 322 and the second abutting shaft 323 are respectively rotatably connected to the wiping frame 34, and the unwinding shaft 322 can rotate under the drive of the power assembly 321, thereby unwinding the wiping element 31; wherein, the first direction Z is the height direction of the wiping frame 34.

[0149] The unwinding assembly 32 includes a power assembly 321, an unwinding shaft 322 and a second abutting shaft 323. The unwinding shaft 322 is rotatably connected to the wiping frame 34. The second abutting shaft 323 can be rotatably connected to the wiping frame 34, and can also be fixedly connected to the wiping member 31. The extension direction of the unwinding shaft 322, the extension direction of the second abutting shaft 323, the extension direction of the first abutting shaft 331 and the extension direction of the winding shaft 332 are all parallel to each other. The power assembly 321 is connected to the unwinding shaft 322 and can drive the unwinding shaft 322 to rotate.

[0150] Exemplarily, the power assembly 321 includes a rotary motor, and an output end of the rotary motor is connected to the unwinding shaft 322 .

[0151] Furthermore, the unwinding assembly 32 may also include a controller, which is electrically connected to the power assembly 321 and is used to control the operation of the power assembly 321 according to a preset time, so that the unwinding assembly 32 unwinds a clean wiping member 31 at preset time intervals.

[0152] The second abutting shaft 323 and the first abutting shaft 331 abut against the roller 100 respectively, and the second abutting shaft 323 and the first abutting shaft 331 can be arranged at the position of the wiping frame 34 close to the roller 100. The wiping member 31 passes through the second abutting shaft 323 and the first abutting shaft 331 from the unwinding shaft 322 to the winding shaft 332 in sequence, and the wiping member 31 covers the side of the second abutting shaft 323 facing the roller 100, and the wiping member 31 covers the side of the first abutting shaft 331 facing the roller 100.

[0153] Specifically, both ends of the unwinding shaft 322 penetrate the wiping frame 34 and can rotate relative to the wiping frame 34. The power assembly 321 is disposed on the wiping frame 34 and connected to the unwinding shaft 322, and is used to drive the unwinding shaft 322 to rotate. Both ends of the second abutting shaft 323 can penetrate the wiping frame 34 and can rotate relative to the wiping frame 34, or can be fixedly connected to the wiping frame 34.

[0154] The first abutting shaft 331 and the second abutting shaft 323 may be arranged at intervals along the first direction Z. When the wiping member 31 of the wiping mechanism 30 performs a wiping operation, the connecting line between the first abutting shaft 331 and the second abutting shaft 323 is tangent to the outer peripheral surface of the roller 100, and the extending direction of the connecting line is the first direction Z. Further, the height direction of the wiping frame 34 may be the same as or intersect with the first direction Z.

[0155] Thus, the first abutting shaft 331 and the second abutting shaft 323 can open the wiping member 31 from both sides, so that the wiping member 31 can provide a larger wiping surface to the roller 100, which helps to improve the wiping effect. The power assembly 321 can control the unwinding of the unwinding shaft 322 in an automated manner, which helps to save labor costs.

[0156] In some embodiments of the present application, Figure 6 As shown, the wiping frame 34 includes a fixed frame 341, a movable frame 342 and a first cylinder 343. The first cylinder 343 is arranged on the fixed frame 341, and the telescopic end of the first cylinder 343 is connected to the movable frame 342; the unwinding shaft 322 and the winding shaft 332 are connected to the fixed frame 341, the first abutment shaft 331 and the second abutment shaft 323 are connected to the movable frame 342, and the movable frame 342 can reciprocate along the second direction X intersecting with the first direction Z under the drive of the first cylinder 343.

[0157] The wiping frame 34 includes a fixed frame 341, a movable frame 342 and a first cylinder 343. The movable frame 342 can move toward or away from the roller 100 under the drive of the first cylinder 343. The first abutting shaft 331 and the second abutting shaft 323 can be arranged on the movable frame 342, and the unwinding shaft 322 and the winding shaft 332 can be arranged on the fixed frame 341. The winding shaft 332, the first abutting shaft 331 and the second abutting shaft 323 can also be arranged on the movable frame 342, and the unwinding shaft 322 can be arranged on the fixed frame 341. The winding shaft 332, the unwinding shaft 322, the first abutting shaft 331 and the second abutting shaft 323 can also be arranged on the movable frame 342.

[0158] The first cylinder 343 includes a cylinder barrel and a piston rod that can reciprocate relative to the cylinder barrel, and the end of the piston rod away from the cylinder barrel is regarded as the telescopic end of the first cylinder 343. The extension direction of the piston intersects with the outer peripheral surface of the roller 100. The cylinder barrel is connected to any one of the fixed frame 341 and the movable frame 342, and the piston rod is connected to the other of the fixed frame 341 and the movable frame 342. Exemplarily, the cylinder barrel is connected to the fixed frame 341, and the end of the piston rod away from the cylinder barrel is connected to the movable frame 342.

[0159] In some embodiments, a guide rail extending along the second direction may be provided on the fixed frame 341, and a sliding member may be provided on the side of the movable frame 342 facing the fixed frame 341. The sliding member is supported on the guide rail in a manner capable of moving along the guide rail, thereby making the movement of the movable frame 342 along the second direction driven by the first cylinder 343 smoother and the movement trajectory less likely to change.

[0160] The extending direction of the piston is regarded as the second direction X. The piston rod can drive the movable frame 342 to move toward or away from the roller 100, so that the first abutting shaft 331 and the second abutting shaft 323 are close to or away from the roller 100, so that the wiping member 31 can contact the roller 100, and no matter what size of the roller 100, the position of the movable frame 342 can be adjusted by the first cylinder 343, so that the first abutting shaft 331 and the second abutting shaft 323 can fit the outer peripheral surface of the roller 100, and then the wiping member 31 can fit the outer peripheral surface of the roller 100, which is conducive to improving the compatibility of the wiping mechanism 30.

[0161] For example, along the radial direction of the roller 100, the piston rod of the first cylinder 343 may be arranged to face the center of the roller 100. This helps to reduce the moving path of the telescopic end. When the connecting line of the first abutting shaft 331 and the second abutting shaft 323 is tangent to the outer peripheral surface of the roller 100, the second direction X is perpendicular to the first direction Z.

[0162] Therefore, the movable frame 342 can be moved along the second direction X by driving the first cylinder 343, thereby changing the distance between the first abutment shaft 331 and the second abutment shaft 323 relative to the roller 100. Regardless of the size of the roller 100, the first abutment shaft 331 and the second abutment shaft 323 can be fitted to the outer circumferential surface of the roller 100, so that the wiping member 31 can be fitted to the outer circumferential surface of the roller 100, and the compatibility is better.

[0163] In some embodiments of the present application, Figure 7 As shown, the transmission member 333 includes a transmission belt 3333, and the winding assembly 33 also includes a tensioning assembly 335. The first abutment shaft 331, the winding shaft 332 and the tensioning assembly 335 are connected through the transmission belt 3333, and the tensioning assembly 335 is configured to keep the transmission belt 3333 in a tensioned state.

[0164] The winding assembly 33 further includes a tensioning assembly 335. The tensioning assembly 335 is disposed on the wiping frame 34. For example, the tensioning assembly 335 can be disposed on the fixed frame 341 or the movable frame 342.

[0165] The transmission member 333 includes a transmission belt 3333. The transmission belt 3333 surrounds the first abutting shaft 331, the winding shaft 332 and the tensioning assembly 335. The tensioning assembly 335 has a tendency to push the transmission belt 3333 away from the first abutting shaft 331 and / or the winding shaft 332, so that the transmission belt 3333 is kept in a tensioned state.

[0166] Therefore, when the position of the first abutment shaft 331 changes along the second direction with the movable frame 342, the tensioning assembly 335 can always maintain the tensioning state of the transmission belt 3333, so that the first abutment shaft 331 and the winding shaft 332 can rotate synchronously, which helps to improve the reliability of the automatic winding function.

[0167] In addition, even if the relative positions of the first abutment shaft 331 and the winding shaft 332 remain unchanged, the transmission belt 3333 may fail in elasticity after long-term use, that is, it cannot maintain the tensioned state. At this time, providing a tensioning component 335 can also help the transmission belt 3333 maintain the tensioned state, thereby improving the reliability of the winding function and the service life of the winding component 33.

[0168] In some embodiments of the present application, the tensioning assembly 335 includes a slider 3351, a first elastic member 3352 and a rotating wheel 3353; a slide groove 3354 extending along the first direction Z is opened on the movable frame 342, and the slider 3351 is arranged in the slide groove 3354 in a manner that it can slide in the slide groove 3354, and the first elastic member 3352 is located on the side of the slide groove 3354 close to the winding shaft 332 along the first direction Z, and one end of the first elastic member 3352 abuts the slider 3351, and the other end abuts the groove wall of the slide groove 3354, and the rotating wheel 3353 is connected to the slider 3351, and the first abutting shaft 331, the winding shaft 332 and the rotating wheel 3353 are connected through a transmission belt 3333.

[0169] The tensioning assembly 335 includes a slider 3351, a first elastic member 3352 and a rotating wheel 3353. The slider 3351 is slidably connected to the wiping frame 34. One end of the first elastic member 3352 is fixed relative to the wiping frame 34, and the other end of the first elastic member 3352 is connected to the slider 3351. The rotating wheel 3353 is connected to the slider 3351 and can rotate relative to the slider 3351. The transmission belt 3333 surrounds the first abutting shaft 331, the winding shaft 332 and the rotating wheel 3353, so that the three rotate synchronously.

[0170] Specifically, the movable frame 342 is provided with a slide groove 3354, and illustratively, the extending direction of the slide groove 3354 is parallel to the first direction Z. One end of the first elastic member 3352 abuts against a side of the slide groove 3354 close to the winding shaft 332, and the other end of the first elastic member 3352 abuts against the slider 3351. The slider 3351 is engaged in the slide groove 3354 and can slide along the slide groove 3354, and the slider 3351 is provided with a pulley that can rotate relative to the slider 3351. The transmission belt 3333 surrounds the first abutting shaft 331, the winding shaft 332 and the rotating wheel 3353, and the first abutting shaft 331, the winding shaft 332 and the rotating wheel 3353 stretch the transmission belt 3333, and the first elastic member 3352 is in a compressed state, so that the transmission belt 3333 is surrounded by a closed figure that is approximately triangular.

[0171] The first elastic member 3352 refers to a member that can undergo elastic deformation. Exemplarily, the first elastic member 3352 includes a compression spring.

[0172] When the position of the movable frame 342 changes along the second direction, the spacing distance between the first abutment shaft 331 and the winding shaft 332 will change, while the length of the transmission belt 3333 will never change. Therefore, when the spacing distance between the first abutment shaft 331 and the winding shaft 332 increases, the transmission belt 3333 will be too tight, which may pose a risk of damage. When the spacing distance between the first abutment shaft 331 and the winding shaft 332 becomes smaller, the transmission belt 3333 may loosen from the first abutment shaft 331 or the winding shaft 332 due to elastic failure, thereby adversely affecting the winding operation of the winding assembly 33.

[0173] In the embodiment of the present application, since a tensioning assembly 335 is additionally provided, the spacing distance between the rotating wheel 3353 of the tensioning assembly 335 and the first abutment shaft 331 remains unchanged. When the spacing distance between the first abutment shaft 331 and the winding shaft 332 increases, the slider 3351 of the tensioning assembly 335 will slide in the slide groove 3354 toward the winding shaft 332, compressing the first elastic member 3352, so that the spacing distance between the rotating wheel 3353 and the winding shaft 332 becomes smaller, thereby making the sum of the spacing distances between the first abutment shaft 331, the winding shaft 332 and the rotating wheel 3353 remain unchanged with the sum of the spacing distances between the two in the initial state, so that the transmission belt 3333 will not be too tight, thereby reducing the possibility of damage to the transmission belt 3333. When the distance between the first abutment shaft 331 and the winding shaft 332 becomes smaller, the slider 3351 will slide in the direction away from the winding shaft 332 under the elastic force of the first elastic member 3352, so that the distance between the rotating wheel 3353 and the winding shaft 332 increases, thereby keeping the sum of the distances between each two of the first abutment shaft 331, the winding shaft 332 and the rotating wheel 3353 unchanged from the sum of the distances between each two in the initial state, thereby reducing the possibility of the transmission belt 3333 loosening.

[0174] Therefore, when the position of the movable frame 342 changes along the second direction, the tensioning assembly 335 can always maintain the tensioned state of the transmission belt 3333, so that the first abutment shaft 331 and the winding shaft 332 can rotate synchronously. While ensuring the compatibility of the winding assembly 33, the service life of the winding assembly 33 is improved, and it also helps to improve the reliability of the automatic winding function.

[0175] In some embodiments of the present application, Figure 8As shown, the power assembly 321 includes a first gear 3211 coaxially connected to the unwinding shaft 322, a rack 3212 meshing with the first gear 3211, and a second cylinder 3213; the second cylinder 3213 is arranged on the wiping frame 34, and the telescopic end of the second cylinder 3213 is connected to the rack 3212. The rack 3212 can reciprocate under the drive of the second cylinder 3213, thereby driving the first gear 3211 and the unwinding shaft 322 coaxially connected to the first gear 3211 to rotate.

[0176] The power assembly 321 includes a first gear 3211, a rack 3212, and a second cylinder 3213. The second cylinder 3213 is disposed on the wiping frame 34, and the rack 3212 is connected to the telescopic end of the second cylinder 3213 and can reciprocate under the drive of the second cylinder 3213. The first gear 3211 is coaxially connected to the unwinding shaft 322, and the first gear 3211 is meshed with the rack 3212, so that the first gear 3211 can be driven by the rack 3212 to rotate.

[0177] For example, in the embodiment of the present application, the telescopic end of the second cylinder 3213 is arranged toward the roller 100. When the telescopic end extends out of the cylinder body of the second cylinder 3213, the second cylinder 3213 drives the rack 3212 to move toward the roller 100, so that the first gear 3211 rotates, driving the unwinding shaft 322 to rotate, thereby unwinding the wiping member 31. Thus, the second cylinder 3213 can provide a stable and easily controllable power, so that the rack 3212 moves smoothly and controllably. Since the rack 3212 is meshed with the first gear 3211, and the first gear 3211 is coaxially connected with the unwinding shaft 322, the first gear 3211 can rotate with the movement of the rack 3212, so that the horizontal movement can be converted into rotation, thereby realizing the rotation of the unwinding shaft 322, so that the wiping member 31 to be replaced leaves the position of abutting the roller 100, and the clean wiping member 31 abuts the roller 100 for wiping.

[0178] Of course, those skilled in the art should understand that in some other embodiments, the power assembly 321 may also include a rotary motor, which is disposed on the wiping frame 34, and the output end of the rotary motor is coaxially connected to the unwinding shaft 322, thereby driving the unwinding shaft 322 to rotate along the unwinding direction. The embodiment of the present application does not specifically limit the type of the power assembly 321, as long as it can drive the unwinding shaft 322 to unwind the wiping member 31.

[0179] In some embodiments of the present application, the first gear 3211 and the unwinding shaft 322 are coaxially connected via a one-way bearing 324, and the one-way bearing 324 is configured such that when the first gear 3211 rotates along the unwinding direction, the unwinding shaft 322 rotates together with the first gear 3211, and when the first gear 3211 rotates in a direction opposite to the unwinding direction, the unwinding shaft 322 remains stationary.

[0180] The one-way bearing 324 refers to a bearing that can rotate freely in one direction and is locked in another direction. For example, the one-way bearing 324 can be a ramp-roller one-way bearing 324 or a wedge-type one-way bearing 324.

[0181] In the embodiment of the present application, the extension stroke of the telescopic end of the second cylinder 3213 is limited. Therefore, when the extension stroke of the telescopic end reaches the upper limit, the telescopic end needs to be retracted into the cylinder body before the next extension operation can be performed. When the telescopic end is retracted into the cylinder body, the second cylinder 3213 will drive the rack 3212 to move in a direction away from the roller. At this time, the first gear 3211 will rotate in the opposite direction to the rotation direction when the telescopic end is extended, which will cause the unwinding shaft 322 to rotate in the opposite direction, thereby rewinding the wiping member 31. Therefore, the unwinding assembly 32 of the embodiment of the present application also includes a one-way bearing 324, which ensures that when the first gear 3211 rotates in the direction opposite to the unwinding direction, it will not drive the unwinding shaft 322 to rotate together.

[0182] Specifically, the first gear 3211 and the unwinding shaft 322 are coaxially connected via a one-way bearing 324. When the rack 3212 drives the first gear 3211 to rotate in the unwinding direction under the drive of the second cylinder 3213, the one-way bearing 324 is locked, so that the position of the unwinding shaft 322 relative to the first gear 3211 is fixed, so that the two can rotate together. When the rack 3212 drives the first gear 3211 to rotate in the direction opposite to the unwinding direction under the drive of the second cylinder 3213, the one-way bearing 324 is unlocked, so that the first gear 3211 rotates independently relative to the unwinding shaft 322, that is, the unwinding shaft 322 does not rotate.

[0183] Thus, the unwinding shaft 322 will only rotate in the unwinding direction, so that the unwinding shaft 322 will only unwind the wiping member 31, and will not rewind the unwound wiping member 31 to be replaced, thereby continuously providing clean wiping members 31 to the roller 100.

[0184] In some embodiments of the present application, the one-way bearing 324 includes a bearing outer ring and a bearing inner ring, the first gear 3211 is connected to the bearing outer ring, and the unwinding shaft 322 is connected to the bearing inner ring; when the first gear 3211 rotates along the unwinding direction, the bearing inner ring is fixed relative to the bearing outer ring, and when the first gear 3211 rotates in a direction opposite to the unwinding direction, the bearing inner ring rotates relative to the bearing outer ring.

[0185] As a result, the unwinding shaft 322 can only rotate along the unwinding direction, so that the wiping member 31 wound thereon can move in one direction, thereby continuously providing clean wiping members 31 to the roller 100 .

[0186] The embodiment of the present application does not specifically limit the type of the one-way bearing 324, and any suitable one-way bearing can be selected.

[0187] In some embodiments of the present application, the cross section of the unwinding shaft 322 is polygonal, and the unwinding shaft 322 is engaged and connected to the inner ring of the bearing, and the cross section is perpendicular to the extension direction of the unwinding shaft 322 .

[0188] In the embodiment of the present application, the cross section of the unwinding shaft 322 is generally a polygon such as a triangle, a rectangle, a pentagon, etc. In some other embodiments, the cross section of the unwinding shaft 322 can also be generally a teardrop shape, an ellipse, etc. The inner ring of the bearing is formed with a groove or a through hole that fits the cross-sectional shape of the unwinding shaft 322, so that the unwinding shaft 322 can be engaged with the inner ring of the bearing.

[0189] Thus, the unwinding shaft 322 can be engaged with the inner ring of the bearing and rotate synchronously with the inner ring of the bearing, and the two are not prone to relative rotation with each other, which is beneficial to improving the unwinding reliability.

[0190] In some embodiments of the present application, Figure 6 As shown, the reel-up shaft 332 is detachably connected to the wiping frame 34 , and the unreeling shaft 322 is detachably connected to the wiping frame 34 .

[0191] One end of the reel shaft 332 is detachably connected to the wiping frame 34 via a coupling 37, and the other end of the reel shaft 332 can be connected to the wiping frame 34 via a coupling 37, or can be configured to be pluggable and rotatable relative to the wiping frame 34. Specifically, the reel assembly 33 also includes a first auxiliary shaft, one end of which is rotatably connected to the wiping frame 34, and the other end of the first auxiliary shaft is connected to the reel shaft 332 via a coupling 37. By removing the screws on the coupling 37, the connection between the coupling 37 can be released so that the coupling 37 can move along the reel shaft 332, thereby creating a gap between the reel shaft 332 and the first auxiliary shaft so that the reel shaft 332 can be removed.

[0192] If the end of the winding shaft 332 away from the first auxiliary shaft can be plugged in and out relative to the wiping frame 34, the winding shaft 332 can be directly pulled out; if the end of the winding shaft 332 away from the first auxiliary shaft is connected to the second auxiliary shaft through the coupling 37, and the second auxiliary shaft is rotationally connected to the wiping member 31, the screws of the coupling 37 can be removed, and the connection of the coupling 37 can be released so that the winding shaft 332 can be removed.

[0193] One end of the unwinding shaft 322 is detachably connected to the wiping frame 34 through the coupling 37, and the other end of the unwinding shaft 322 is detachably connected to the one-way bearing 324 through the coupling 37, or can be configured to be pluggable relative to the one-way bearing 324. Specifically, the unwinding assembly 32 also includes a third auxiliary shaft, one end of which is rotatably connected to the wiping frame 34, and the other end of the third auxiliary shaft is connected to the unwinding shaft 322 through the coupling 37. By removing the screws on the coupling 37, the connection between the coupling 37 can be released so that the coupling 37 can move along the unwinding shaft 322, thereby creating a gap between the unwinding shaft 322 and the third auxiliary shaft so that the unwinding shaft 322 can be removed.

[0194] If the end of the unwinding shaft 322 away from the third auxiliary shaft can be plugged in and out relative to the one-way bearing 324, the unwinding shaft 322 can be directly pulled out; if the end of the unwinding shaft 322 away from the third auxiliary shaft is connected to the fourth auxiliary shaft through the coupling 37, and the fourth auxiliary shaft is connected to the one-way bearing 324, the screws of the coupling 37 can be removed to release the connection of the coupling 37 so that the unwinding shaft 322 can be removed.

[0195] As a result, it is easier to replace the wiping piece 31. When the wiping piece 31 on the unwinding shaft 322 is used up or you want to replace it with another type of wiping piece 31, you can remove the unwinding shaft 322 and the winding shaft 332, take out the wiping piece 31 to be replaced, and replace it with a new one. The replacement operation is simple, which is conducive to improving the replacement efficiency.

[0196] In some embodiments of the present application, Figure 8 As shown, a second elastic member 325 is formed on the shaft wall of the unwinding shaft 322. The second elastic member 325 can be elastically deformed under the action of external force. When the reel wound with the wiping member 31 is sleeved on the unwinding shaft 322, the second elastic member 325 abuts against the inner wall of the reel.

[0197] The second elastic member 325 is arranged on the surface of the unwinding shaft 322, and the wiping member 31 is wound on the reel. When the reel is sleeved on the unwinding shaft 322, the second elastic member 325 is compressed by the reel to provide a radial abutment force to the reel, so that the relative position of the reel and the unwinding shaft 322 is fixed, so that the reel can rotate along the unwinding direction with the unwinding shaft 322.

[0198] The second elastic member 325 refers to a member that can be elastically deformed under the action of an external force. Exemplarily, the second elastic member 325 includes but is not limited to a rubber block.

[0199] Exemplarily, the second elastic member 325 may be disposed at either end of the unwinding shaft 322 .

[0200] As another example, the second elastic member 325 may be disposed at a middle position of the unwinding shaft 322 .

[0201] As another example, the number of the second elastic members 325 can be multiple, and the multiple second elastic members 325 are arranged at intervals on the unwinding shaft 322. For example, the multiple second elastic members 325 can be arranged at intervals on the unwinding shaft 322 along the same direction, and the multiple second elastic members 325 can also be arranged at intervals along the circumferential direction of the unwinding shaft 322.

[0202] The embodiment of the present application does not impose any specific limitation on the number and arrangement direction of the second elastic members 325 , as long as the positions of the sleeve and the unwinding shaft 322 are not easily moved relative to each other when they are engaged.

[0203] Thus, the position of the reel relative to the unwinding shaft 322 is fixed, and when the unwinding shaft 322 is unwinding, the reel can rotate synchronously with the unwinding shaft 322. Moreover, the reel can be taken out of or inserted into the unwinding shaft 322 by applying an external force greater than the second elastic member 325, so that the position of the reel relative to the unwinding shaft 322 can be adjusted, and a new wiping member 31 and a reel wound with the wiping member 31 can be replaced, which is flexible and convenient to use.

[0204] In some embodiments of the present application, Fig. 9 As shown, the winding shaft 332 is provided with a pressing block 334, and the pressing block 334 is used to press the wiping member 31 to the surface of the winding shaft 332. The pressing block 334 is detachably connected to the winding shaft 332 through a screw member.

[0205] The wiping member 31 needs to be at least partially connected to the reel 332. In the embodiment of the present application, the reel 332 fixes the wiping member 31 through a pressing block 334 and a screw. The screw passes through the pressing block 334 and the reel 332 in sequence, and the pressing block 334 is detachably mounted on the reel 332. When in use, the screw is loosened to form a gap between the pressing block 334 and the reel 332, and a portion of the wiping member 31 is placed in the gap, and then the screw is tightened so that the pressing block 334 presses the wiping member 31 against the reel 332.

[0206] Illustratively, the threaded member may be a screw, a nut, or the like.

[0207] Thus, it is convenient to install and remove the wiping member 31 to the winding shaft 332, and the distance between the pressing block 334 and the winding shaft 332 can be adjusted by rotating the screw member, and the distance can be reduced so that the pressing block 334 can press the wiping member 31 tightly against the surface of the winding shaft 332, and the distance can be increased to loosen the wiping member 31. The structure is simple and easy to use.

[0208] In some embodiments of the present application, Figures 3 to 5 As shown, the roller cleaning device 2000 also includes a support frame 40, and the wiping mechanism 30 is arranged on the support frame 40 in a manner that it can rotate between a working position and a replacement position. A first matching piece 35 is provided on the support frame 40, and a second matching piece 36 is provided on the wiping mechanism 30; wherein, in the working position, the second matching piece 36 is matched and connected with the first matching piece 35.

[0209] The roller cleaning device 2000 further includes a support frame 40. The wiping mechanism 30 is rotatably connected to the support frame 40. When the wiping member 31 of the wiping mechanism 30 abuts against the roller 100 and performs a wiping operation, the wiping mechanism 30 is considered to be in a working position; a certain position of the wiping mechanism 30 away from the roller 100 is considered to be a replacement position, for example, a position where the wiping mechanism 30 contacts the support surface in a stable state can be considered to be a replacement position.

[0210] The support frame 40 is provided with a first matching piece 35, and the wiping mechanism 30 is provided with a second matching piece 36. The first matching piece 35 and the second matching piece 36 can be connected to each other in a matching manner, and can also be disconnected.

[0211] Two support frames 40 may be provided, and the two support frames 40 are spaced apart from each other in the axial direction of the roller 100, and the wiping frame 34 is located between the two support frames 40. A rotating shaft is provided to sequentially penetrate one support frame 40, the wiping frame 34, and the other wiping frame 34, so that the wiping frame 34 can rotate relative to the two wiping frames 34 around the rotating shaft. A second matching piece 36 is provided at one end of the wiping frame 34 away from the rotating shaft, and a first matching piece 35 is provided on at least one support frame 40, and the first matching piece 35 is located on the rotating path of the second matching piece 36 rotating with the wiping frame 34.

[0212] Thus, when the wiping mechanism 30 is in the working position, it can wipe the roller 100. When the wiping mechanism 30 is changed, it is away from the roller 100, thereby reducing the influence on the operation of the roller 100 when replacing the wiping member 31 or performing maintenance on the wiping mechanism 30, and the wiping member 31 can be replaced without affecting the operation of the roller 100, which helps to improve production efficiency.

[0213] In some embodiments of the present application, see Figures 3 to 5The first mating piece 35 can be switched between the first posture and the second posture by rotating. When the first mating piece 35 is in the first posture, the first mating piece 35 and the second mating piece 36 are locked. When the first mating piece 35 is in the second posture, the first mating piece 35 and the second mating piece 36 are unlocked.

[0214] The first matching piece 35 is rotatably connected to the wiping mechanism 30, and the second matching piece 36 has a gap for the first matching piece 35 in the second posture to pass through. When the wiping mechanism 30 is in the working position and the first matching piece 35 is in the first posture, in the same projection plane parallel to the first direction Z, the projection of the first matching piece 35 and the projection of the second matching piece 36 partially overlap; when the wiping mechanism 30 is in the working position and the first matching piece 35 is in the second posture, in the same projection plane parallel to the first direction Z, the projection of the first matching piece 35 and the projection of the second matching piece 36 do not overlap.

[0215] Specifically, the first matching piece 35 can be configured to be approximately bar-shaped, and the second matching piece 36 can be configured to be approximately U-shaped. When the first matching piece 35 rotates to the second posture, the first matching piece 35 can pass through the gap of the second matching piece 36 from one side of the second matching piece 36 to the other side of the second matching piece 36. When the first matching piece 35 rotates to the first posture, the first matching piece 35 is blocked by the second matching piece 36 and cannot pass through the second matching piece 36.

[0216] When in use, the first matching piece 35 is rotated to the second posture, and the wiping mechanism 30 is rotated to the working position, so that the first matching piece 35 passes through the gap of the second matching piece 36. Then the first matching piece 35 is rotated to the first posture, so that the first matching piece 35 and the second matching piece 36 abut against each other to achieve the engagement of the two.

[0217] Therefore, by rotating the first matching member 35 , the wiping mechanism 30 can be fixed on the support frame 40 , or released from the support frame 40 , thereby changing the position of the wiping mechanism 30 , with a simple structure and ingenious design.

[0218] In some embodiments of the present application, Fig.10 As shown, the roller cleaning device 2000 also includes a support frame 40, and the scraping mechanism 20 is arranged on the support frame 40; the scraping mechanism 20 includes a scraping assembly 21 and a third cylinder 22, and the scraping assembly 21 can rotate relative to the support frame 40; the telescopic end of the third cylinder 22 is connected to the scraping assembly 21, and the scraping assembly 21 can rotate toward or away from the outer peripheral surface of the roller 100 under the drive of the third cylinder 22.

[0219] The scraping mechanism 20 includes a scraping assembly 21 and a third cylinder 22. The third cylinder 22 is disposed on the support frame 40, and the extension direction of the telescopic end of the third cylinder 22 has an intersection with the outer peripheral surface of the roller 100, so that the scraping assembly 21 can be driven by the third cylinder 22 to rotate toward or away from the outer peripheral surface of the roller 100.

[0220] Exemplarily, the telescopic end of the third cylinder 22 is connected to the scraper assembly 21 via a rod end joint bearing.

[0221] Exemplarily, the third cylinder 22 may be a pen-shaped cylinder.

[0222] Therefore, when performing scraping operations, the third cylinder 22 can drive the scraping component 21 to rotate, thereby changing the angle of the scraping component 21 relative to the roller 100, so that the scraping component 21 can abut against the outer peripheral surface of the roller 100, and for rollers 100 of different sizes, the scraping component 21 can be driven by the third cylinder 22 to abut against the outer peripheral surface of the roller 100, thereby performing a good scraping operation with better compatibility.

[0223] In some embodiments of the present application, Fig.11 As shown, a first limiting member 23 is provided on the support frame 40, and a second limiting member 24 is provided on the scraping assembly 21; the second limiting member 24 protrudes from the surface of the scraping assembly 21, and the first limiting member 23 is located on the rotation path of the scraping assembly 21, and is used to limit the rotation of the scraping assembly 21 through the cooperation of the first limiting member 23 and the second limiting member 24.

[0224] The second limiter 24 can be disposed on the surface of the scraper assembly 21 facing the roller 100 , or on the edge of the scraper assembly 21 . The first limiter 23 is disposed on the support and on the rotation path of the second limiter 24 .

[0225] Therefore, after the scraper assembly 21 rotates to a certain angle, the second limit member 24 contacts the first limit member 23 and is blocked by the first limit member 23, thereby limiting the rotation angle of the scraper assembly 21, so that the angle of the scraper assembly 21 relative to the roller 100 is maintained within a reasonable range, reducing the possibility of the scraper assembly 21 causing damage to the outer peripheral surface of the roller 100.

[0226] In some embodiments of the present application, Fig.12 and Fig.13 As shown, the scraping assembly 21 includes a scraping frame 211 and a scraper 212. The scraper 212 is installed on the scraping frame 211, and the telescopic end of the third cylinder 22 is connected to the scraping frame 211. The scraping mechanism 20 also includes at least one pressing and releasing assembly 25, and the scraper 212 is detachably installed on the scraping frame 211 through the pressing and releasing assembly 25.

[0227] The scraping assembly 21 includes a scraping frame 211 and a scraper 212. The two support frames 40 are spaced apart from each other, and the scraping frame 211 is located between the two support frames 40. The rotating shaft passes through one support frame 40, the scraping frame 211, and the other support frame 40 in sequence, and the scraping frame 211 can rotate relative to the support frame 40 around the rotating shaft. The telescopic end of the third cylinder 22 is connected to the scraping frame 211. The scraper 212 is installed on the side of the scraping frame 211 facing the roller 100.

[0228] The scraping mechanism 20 further includes a pressing assembly 25. The pressing assembly 25 can press the scraper 212 against the scraping frame 211, and can also release the scraper 212 so that the scraper 212 can be removed from the scraping frame 211. A plurality of pressing assemblies 25 can be provided, and the plurality of pressing assemblies 25 are spaced apart and arranged along the extension direction of the scraping frame 211.

[0229] Thus, the scraper 212 can be replaced by the pressing assembly 25, so that the scraper 212 can meet the scraping requirements and maintain the scraping effect. In addition, the third cylinder 22 can pull the scraper frame 211 away from the roller 100, so that the scraper 212 can be replaced while the roller 100 is operating normally, without the roller 100 stopping to wait, which helps to improve production efficiency.

[0230] In some embodiments of the present application, Fig.12 and Fig.13 As shown, the scraper frame 211 includes a first plate 2111 and a second plate 2112 facing each other, the pressing assembly 25 includes a cam 251 and a connecting member 252 that passes through the first plate 2111 and the second plate 2112, the cam 251 is rotatably connected to one end of the connecting member 252, the scraper 212 is located between the first plate 2111 and the second plate 2112, and the cam 251 can switch between a first state and a second state by rotating. When the cam 251 is in the first state, the cam 251 presses the first plate 2111 and the second plate 2112; when the cam 251 is in the second state, the cam 251 releases the first plate 2111 and the second plate 2112.

[0231] The scraper frame 211 includes a first plate 2111 and a second plate 2112. The first plate 2111 and the second plate 2112 face each other, and the scraper 212 is located between the first plate 2111 and the second plate 2112. A portion of the pressing assembly 25 penetrates the first plate 2111 and the second plate 2112, and is configured to be able to change the movable spacing of the first plate 2111 relative to the second plate 2112, thereby achieving the pressing of the scraper 212.

[0232] The pressing and releasing assembly 25 includes a cam 251 and a connecting member 252. One end of the connecting member 252 forms a stopper abutting against the first plate 2111, and the other end of the connecting member 252 is provided with a through hole extending along its radial direction. The cam 251 is provided with an eccentric through hole, and the rotating shaft passes through the through hole on the connecting member 252 and the through hole on the cam 251, so that the cam 251 is rotatably connected to the connecting member 252. Rotating the cam 251 can change the distance between the surface of the cam 251 close to the second plate 2112 and the second plate 2112. Rotating the cam 251 minimizes the distance between the surface of the cam 251 close to the second plate 2112 and the second plate 2112, and this state is regarded as the first state; rotating the cam 251 maximizes the distance between the surface of the cam 251 close to the second plate 2112 and the second plate 2112, and this state is regarded as the second state. When the cam 251 is in the first state, the cam 251 presses the first plate 2111 and the second plate 2112 ; when the cam 251 is in the second state, the cam 251 releases the first plate 2111 and the second plate 2112 .

[0233] Furthermore, a handle is provided on the cam 251, and the handle can drive the cam 251 to rotate relative to the connecting member 252. By pressing down or lifting the handle, the first plate 2111 and the second plate 2112 can be clamped or loosened quickly.

[0234] Therefore, the scraper 212 can be fixed between the first plate 2111 and the second plate 2112 by rotating the cam 251, or the scraper 212 can be taken out from between the loosened first plate 2111 and the second plate 2112, so as to facilitate the disassembly and replacement of the scraper 212.

[0235] In some embodiments of the present application, Fig.10 As shown, the scraping mechanism 20 further includes a water receiving tray 26 , and the water receiving tray 26 is located below the scraping assembly 21 along the direction of gravity.

[0236] The scraping mechanism 20 further includes a water receiving tray 26. The shape of the water receiving tray 26 can be configured to be approximately rectangular. In the direction of gravity, the water receiving tray 26 is located below the scraping assembly 21. The liquid is blocked by the scraper 212 and moves along the scraper 212 toward the scraping frame 211, flows through the scraping frame 211 to the edge of the scraping frame 211, and drips from the scraping frame 211 into the water receiving tray 26, and is collected by the water receiving tray 26. The water receiving tray 26 can be connected to a sewage treatment pipeline, and the liquid in the water receiving tray 26 can be discharged through the sewage treatment pipeline.

[0237] Furthermore, a scraper capable of contacting the roller 100 is provided on one side of the water receiving tray 26 close to the roller 100. The liquid is first scraped off by the scraper 212, and then scraped off by the scraper for the second time, and the liquid flows into the water receiving tray 26 along the scraper.

[0238] Therefore, the liquid scraped by the scraping assembly 21 can be collected in the water receiving tray 26, which is helpful for the centralized treatment of the liquid and can reduce the impact of the random flow and splashing of the liquid on the working environment of the roller 100.

[0239] In some embodiments of the present application, the scraping mechanism 20 further includes a storage box, and the water receiving tray 26 is connected to the storage box.

[0245] The soaking mechanism 10 further comprises a cleaning liquid pipeline and a cleaning liquid storage tank. The cleaning liquid pipeline is connected to the nozzle 12 and the cleaning liquid storage tank. A pump is provided on the cleaning liquid pipeline to provide power for conveying the cleaning liquid.

[0246] Therefore, the spraying area formed by the coordinated spraying of the plurality of spray heads 12 can cover a larger area of ​​the roller 100, which helps to reduce cleaning dead angles and improve the cleaning effect.

[0247] In some embodiments of the present application, the roller cleaning device 2000 further includes a support frame 40 ; the soaking frame 11 is disposed on the support frame 40 in a manner that it can rotate relative to the support frame 40 .

[0248] The two support frames 40 are spaced apart from each other, and the soaking frame 11 is located between the two support frames 40. The soaking frame 11 is rotatably connected to the support frames 40.

[0249] Thus, the angle of the wetting frame 11 relative to the roll 100 can be changed, and the spraying angle of the nozzle head 12 relative to the roll 100 can be adjusted.

[0250] In some embodiments of the present application, Fig.15 and Fig.16 As shown, the soaking rack 11 includes a third plate 111, a fourth plate 112, a rotating shaft 113 and an adjustable angle bolt 114. Along the extension direction of the third plate 111, the fourth plate 112 is located on the opposite sides of the third plate 111. The fourth plate 112 is rotatably connected to the support frame 40 through the rotating shaft 113, and the nozzle 12 is arranged on the third plate 111; wherein, the fourth plate 112 is provided with an arc-shaped slide groove 115, and the adjustable angle bolt 114 passes through the arc-shaped slide groove 115 and is threadedly connected to the support frame 40, and the angle of the adjustable angle bolt 114 relative to the support frame 40 is adjustable.

[0251] The soaking frame 11 includes a third plate 111, a fourth plate 112, a rotating shaft 113 and an adjustable angle bolt 114. The extension direction of the third plate 111 is parallel to the axial direction of the roller 100. Along the extension direction of the third plate 111, the support frames 40 are respectively located on both sides of the third plate 111. The fourth plate 112 is arranged between the third plate 111 and the support frame 40, and the fourth plate 112 is connected to the third plate 111. The rotating shaft 113 is arranged to pass through the support frame 40 and the soaking frame 11. The extension direction of the rotating shaft 113 is parallel to the extension direction of the third plate 111. The soaking frame 11 can rotate relative to the support frame 40 around the rotating shaft 113.

[0252] The fourth plate 112 is provided with an arc-shaped slide groove 115. The adjustable angle bolt 114 passes through the arc-shaped slide groove 115 and is threadedly connected to the support frame 40. The extension direction of the adjustable angle bolt 114 has an angle less than 90 degrees with the plate surface of the fourth plate 112. In the same projection plane perpendicular to the third plate 111, the adjustable angle bolt 114 is rotated so that the projection of the adjustable angle bolt 114 coincides with the projection of the slide groove 3354, and the adjustable angle bolt 114 can slide in the slide groove 3354. In the same projection plane perpendicular to the third plate 111, the adjustable angle bolt 114 is rotated so that the projection of the adjustable angle bolt 114 coincides with the projection of the slide groove 3354, and one side of the adjustable angle bolt 114 abuts against the slide groove 3354 to prevent the slide groove 3354 from moving.

[0253] Thus, the fourth plate 112 supports the third plate 111 from both sides of the third plate 111, which helps to improve the firmness of the fourth plate 112 supporting the third plate 111. The fourth plate 112 can rotate relative to the support frame 40, and the angle of the third plate 111 and the nozzle 12 disposed thereon can be changed by rotating the fourth plate 112, so that the nozzle 12 can spray the cleaning liquid at a suitable angle. The angle of the third plate 111 adjusted at a certain angle can be kept constant by rotating the adjustable angle bolt 114.

[0270] The non-woven fabric lifting mechanism includes a rotating wheel 3353, a transmission belt 3333, a tensioning mounting block (slider 3351), a limiting slider 3351, a spring (first elastic member 3352), a spring mounting seat, a floating plate (movable frame 342), a non-woven fabric pressing shaft (second abutting shaft 323), a cylinder connecting plate (movable frame 342), a sliding groove, a cylinder mounting plate (fixed frame 341), and a first cylinder 343.

[0271] The mechanism mounting base plate (wiping frame 34) includes a cylinder mounting plate (fixed frame 341) and a floating plate (moving frame 342), the first cylinder 343 is arranged on the cylinder mounting plate (fixed frame 341), the floating plate (moving frame 342) is provided with a cylinder connecting plate, and the telescopic end of the first cylinder 343 is connected to the cylinder connecting plate. The cylinder mounting plate (fixed frame 341) is provided with a sliding groove, and the floating plate (moving frame 342) has a matching piece, which is engaged with the sliding groove and can slide relative to the sliding groove. The two floating plates (moving frames 342) are arranged to be separated from each other, and the first abutting shaft 331 and the non-woven fabric pressing shaft (second abutting shaft 323) are provided between the two floating plates (moving frames 342). The first cylinder 343 drives the non-woven fabric pressing shaft (second abutting shaft 323) to approach the roller 100, so that the non-woven fabric (wiping member 31) presses the roller 100, ensuring that the non-woven fabric can effectively rub the roller 100.

The transmission belt 3333 surrounds the first abutting shaft 331, the winding shaft 332, and the rotating wheel 3353. The spring (first elastic member 3352 ) is in a compressed state, and is used to keep the transmission belt 3333 in a tensioned state.

[0273] The non-woven fabric winding mechanism includes a first transmission wheel 3331, a damper 38, a support plate, a pressure block 334, a winding shaft 332, a coupling 37, and a connecting shaft (third auxiliary shaft).

[0274] One side of the non-woven fabric (wiping member 31) is pressed against the reel 332 by a pressing block 334. Two support plates are spaced apart from each other and are arranged on the mechanism mounting base plate (wiping frame 34). The first transmission wheel 3331 is rotatably connected to one support plate, and one end of the reel 332 is coaxially connected to the first transmission wheel 3331 through a damper 38. When the resistance of the reel 332 is greater than the set value of the damper 38, the reel 332 does not rotate synchronously with the first transmission wheel 3331. The connecting shaft (third auxiliary shaft) is rotatably connected to the other support plate, and the reel 332 is connected to the connecting shaft (third auxiliary shaft) through a coupling 37. The damper 38 is configured with a hexagonal through hole, and the cross section of the reel 332 is configured to be hexagonal and inserted into the through hole. When replacing the non-woven fabric (wiping member 31), the coupling 37 is loosened and the reel 332 is taken out.

[0275] The nonwoven fabric unwinding mechanism includes a second cylinder 3213, a rack 3212 mounting plate, a rack 3212, a one-way bearing 324, a first gear 3211, a tensioning block (a second elastic member 325), a mounting plate, an unwinding shaft 322, a coupling 37, and a first auxiliary shaft.

[0276] The two mounting plates are separated from each other and are arranged on the mechanism mounting base plate (wiping frame 34). A second cylinder 3213 is arranged on one mounting plate, and the telescopic end of the second cylinder 3213 is connected to the rack 3212 mounting plate, and the rack 3212 is arranged on the rack 3212 mounting plate. The one-way bearing 324 is installed in the first gear 3211, and the inner ring of the one-way bearing 324 is configured with a hexagonal through hole. The unwinding shaft 322 is configured as a hexagonal prism inserted into the hexagonal through hole, and the first gear 3211 is meshed with the rack 3212. A tensioning block (second elastic member 325) is arranged on the unwinding shaft 322 to abut against the roll of non-woven fabric (wiping member 31). One end of the unwinding shaft 322 away from the first gear 3211 is connected to the first auxiliary shaft through a coupling 37, and the first auxiliary shaft is rotatably connected to the mounting plate.

[0277] When the rack 3212 drives the first gear 3211 to rotate in the unwinding direction, the unwinding shaft 322 rotates in the unwinding direction under the action of the one-way bearing 324 to unwind the nonwoven fabric (wiping member 31). When the rack 3212 drives the first gear 3211 to rotate in the winding direction, the unwinding shaft 322 is stationary under the action of the one-way bearing 324.

[0278] The first abutment shaft 331 is coaxially connected with the first transmission wheel 3331, and the transmission belt 3333 is transmission-connected with the first transmission wheel 3331, the second transmission wheel 3332 and the rotating wheel 3353. When the non-woven fabric (wiping member 31) is unwound, the friction of the roller 100 drives the non-woven fabric (wiping member 31) to press against the first abutment shaft 331 and rotate, and the first transmission wheel 3331 rotates accordingly, driving the second transmission wheel 3332 and the winding shaft 332 to rotate, so that the replaced dirty fabric can be automatically wound up. The diameter of the first abutment shaft 331 is smaller than the diameter of the reel shaft 332, and the transmission belt 3333 drives the first transmission wheel 3331 and the second transmission wheel 3332 to rotate at the same rotation angle. The path of the non-woven fabric (wiping piece 31) around the reel shaft 332 is larger than the path of the non-woven fabric (wiping piece 31) around the first abutment shaft 331, so that the non-woven fabric is kept in a tensioned state, and under the action of the damper 38, the tensioning force will not be too large to cause the belt to break. The second cylinder 3213 can be controlled to move regularly to achieve the regular replacement of the non-woven fabric (wiping piece 31), and the replacement time can be set according to the actual use time and cleanliness of the non-woven fabric.

[0279] A sensor may be provided on the unwinding shaft 322 to give an alarm when the nonwoven fabric (wiping member 31) has been used up.

[0280] The roller cleaning device 2000 can sequentially wet, scrape and dry-wipe the roller 100. First, the cleaning liquid is sprayed on the roller 100 through the soaking mechanism 10, and then the cleaning liquid, particles, carbon powder and other dirt on the roller 100 are scraped into the water receiving tray 26 for reflux treatment through the scraping mechanism 20, and finally the non-woven fabric (wiping piece 31) that is automatically rolled up is used for dry wiping to ensure that the front surface of the roller 100 and the pole piece 200 is clean and free of particles, carbon powder and cleaning liquid. The wiping mechanism 30 can unwind and automatically roll up the non-woven fabric (wiping piece 31) at a regular time, without the need for frequent manual replacement of the non-woven fabric. The time for changing the fabric can be controlled according to the effect of the non-woven fabric (wiping piece 31) wiping the roller, and the non-woven fabric (wiping piece 31) can be automatically replaced at a regular time to avoid friction damage and rolling into the roller pole piece 200. The use of the roller cleaning device 2000 can avoid the trouble and waste of manual roller wiping, and can replace the scraper 212 in time, thereby reducing the cost of lithium batteries in the production process and improving the battery quality.
