[0002] There is a problem of cleaning the coating steel roller in lithium battery coating equipment or printing equipment. Take lithium battery coating equipment as an example. During the coating process, if the foil is damaged, the slurry on the foil will stick to the coating steel roller through the damaged part. If the coating steel roller is not cleaned in time, the roller diameter of the coating steel roller in this area will increase, and the coating thickness on the foil will become thinner, affecting the coating quality.

[0003] At the same time, if the roller diameter is too large, there will be a risk of scraping the foil, causing the foil to be damaged again, seriously affecting production.

[0004] When the foil is damaged, the slurry on the foil leaks onto the surface of the coating steel roller and easily forms dry lumps. The friction between the dry lumps on the surface of the coating steel roller and the foil will cause scratches on the foil, affecting the coating quality.

[0005] In existing coating equipment, scrapers, brushes and non-woven fabrics are generally used to clean pollutants in the coating steel roller. Cleaning tools such as scrapers, brushes and non-woven fabrics are difficult to completely clean the pollutants on the surface of the coating steel roller, which affects the coating quality.

[0036] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0037] Reference Figures 1 to 5 An example of the present invention provides a steel roller wiping device, which includes a frame 100, a wiping mechanism 300 and a spraying mechanism 400 arranged on the frame 100.

[0038] The frame 100 includes two wall panels and a connecting rod for connecting the two wall panels, and both ends of the steel roller 200 are rotatably connected to the two wall panels respectively.

[0039] In terms of position, the wiping mechanism 300 is located on one side of the steel roller 200 , and the spraying mechanism 400 is located above the wiping mechanism 300 .

[0040] Structurally, the wiping mechanism 300 includes a support roller 310, a plurality of wiping sponges 320 arranged on the support roller 310, and a first driving assembly 330 for driving the support roller 310 to rotate. The plurality of wiping sponges 320 are distributed in a circular array along the axis of the support roller 310. The wiping sponges 320 are of a rectangular structure. The length direction of the wiping sponges 320 extends along the axial direction of the support roller 310. The support roller 310 is parallel to the steel roller 200.

[0041] Specifically, the number of the wiping sponges 320 is four.

[0042] Furthermore, the spray mechanism 400 is used to spray cleaning liquid onto the wiping sponge 320, and includes a liquid supply component 410, a spray pipe 420 and a plurality of spray heads 430 arranged on the spray pipe 420. The liquid supply component 410 is used to provide cleaning liquid into the spray pipe 420, and the plurality of spray heads 430 are arranged in sequence along the length direction of the spray pipe 420. The spray pipe 420 is parallel to the support roller 310 and is located above the support roller 310, and the plurality of spray heads 430 are all facing the support roller 310.

[0043] When contaminants adhere to the surface of the steel roller 200, the wiping sponge 320 is fixed on the supporting roller 310 at the side of the supporting roller 310 away from the steel roller 200, and the first driving assembly 330 drives the supporting roller 310 to rotate, and the supporting roller 310 drives the wiping sponge 320 to rotate around the axis of the supporting roller 310. When one of the wiping sponges 320 rotates to the top of the supporting roller 310, the first driving assembly 330 stops working. Then, the liquid supply assembly 410 provides cleaning liquid into the spray pipe 420, and the cleaning liquid is sprayed from the spray head 430 onto the wiping sponge 320 on the top of the supporting roller 310. After the wiping sponge 320 absorbs the cleaning liquid, the liquid supply assembly 410 stops working. Then, the first driving assembly 330 continues to drive the supporting roller 310 to rotate 90 degrees, so that the wiping sponge 320 absorbing the cleaning liquid abuts against the roller surface of the steel roller 200, and the other wiping sponge 320 is located on the top of the supporting roller 310. Then, the steel roller 200 rotates, and the wiping sponge 320 absorbing the cleaning liquid wipes the pollutants on the roller surface of the steel roller 200. At the same time, the liquid supply assembly 410 provides the cleaning liquid into the spray pipe 420, and the cleaning liquid is sprayed from the spray head 430 onto the wiping sponge 320 on the top of the supporting roller 310. Then, the first driving assembly 330 continues to drive the supporting roller 310 to rotate 90 degrees, so that the other wiping sponge 320 absorbing the cleaning liquid abuts against the roller surface of the steel roller 200. Then, the steel roller 200 rotates, and the wiping sponge 320 absorbing the cleaning liquid wipes the pollutants on the roller surface of the steel roller 200. The wiping sponge 320 that has wiped the pollutants is removed and replaced with a new wiping sponge 320. If the contaminants on the roller surface of the steel roller 200 are wiped clean, the spray mechanism 400 does not need to spray the cleaning liquid on the wiping sponge 320 located on the top of the supporting roller 310. Then, the first driving assembly 330 continues to drive the supporting roller 310 to rotate 90 degrees, so that the dry wiping sponge 320 abuts against the roller surface of the steel roller 200. Then, the steel roller 200 rotates, and the dry wiping sponge 320 wipes the liquid remaining on the roller surface of the steel roller 200.

[0044] Therefore, the embodiment of the present invention sprays cleaning liquid on the wiping sponge 320 through the spray mechanism 400, so that the wiping sponge 320 that absorbs the cleaning liquid can easily wipe off the pollutants on the steel roller 200, and the dry wiping sponge 320 can also be used to wipe off the liquid remaining on the roller surface of the steel roller 200, thereby ensuring that the roller surface of the steel roller 200 is clean and improving the coating quality.

[0045] In some preferred embodiments, the support roller 310 includes an adsorption shaft 311 and an outer sleeve 312 sleeved on the adsorption shaft 311, the adsorption shaft 311 is fixed on the frame 100, a vacuum chamber 313 is arranged inside the adsorption shaft 311, one end of the vacuum chamber 313 is connected to a negative pressure device 340, a plurality of first through holes 314 connected to the vacuum chamber 313 are arranged on the outer periphery of the adsorption shaft 311, a plurality of accommodating grooves 315 are arranged on the outside of the outer sleeve 312, the accommodating grooves 315 are used to accommodate the wiping sponge 320, a plurality of second through holes 316 are arranged between the accommodating grooves 315 and the inner ring of the outer sleeve 312, and the first driving assembly 330 is used to drive the outer sleeve 312 to rotate relative to the adsorption shaft 311.

[0046] It can be understood that when the negative pressure device 340 is started, negative pressure is formed in the vacuum chamber 313 in the adsorption shaft 311, and the vacuum chamber 313 is connected to the inner ring of the outer sleeve 312 through the first through hole 314, and the inner ring of the outer sleeve 312 is connected to the accommodating groove 315 through the second through hole 316. When the wiping sponge 320 is placed in the accommodating groove 315, the wiping sponge 320 is adsorbed in the accommodating groove 315, thereby facilitating the fixation of the wiping sponge 320 and not being affected by the rotation of the outer sleeve 312.

[0047] Specifically, the negative pressure device 340 is a vacuum pump, which is connected to the adsorption shaft 311 through a vacuum tube. The vacuum tube is also connected to a pressure gauge, which can display the real-time pressure in the vacuum chamber 313, making it easier for operators to monitor the working data.

[0048] In some preferred embodiments, the number of the accommodating grooves 315 is four, and two partition plates 317 are arranged on the adsorption shaft 311. The outward side of the partition plate 317 is an arc surface, and the outer sleeve 312 is sleeved on the partition plate 317. The two partition plates 317 divide the adsorption shaft 311 and the outer sleeve 312 into an adsorption chamber 318 and a non-adsorption chamber 319. The first through hole 314 is connected to the adsorption chamber 318, and the adsorption chamber 318 faces the top and the side close to the steel roller 200, so that the accommodating groove 315 located at the top of the outer sleeve 312 and the side close to the steel roller 200 is connected to the adsorption chamber 318, and the accommodating chamber located at the bottom of the outer sleeve 312 is connected to the non-adsorption chamber 319.

[0049] It can be understood that the wiping sponge 320 located at the top of the outer sleeve 312 and close to the side of the steel roller 200 is adsorbed in the accommodating groove 315. When the wiping sponge 320 has finished wiping, the first driving assembly 330 drives the outer sleeve 312 to rotate 90 degrees, so that the wiping sponge 320 that has finished wiping is located at the bottom of the outer sleeve 312. At this time, the accommodating cavity at the bottom of the outer sleeve 312 is connected to the non-adsorption cavity 319, and the wiping sponge 320 at the bottom of the outer sleeve 312 loses its adsorption force and falls freely under the action of gravity, thereby realizing automatic unloading of waste wiping sponges 320.

[0050] In some preferred embodiments, a waste box 500 is further included. The waste box 500 is located directly below the outer sleeve 312. The waste box 500 is used to receive the wiping sponge 320 after wiping.

[0051] It is understandable that the wiping sponge 320 at the bottom of the outer sleeve 312 loses its adsorption force and falls freely into the waste box 500 under the action of gravity, so that the waste wiping sponge 320 can be recycled to prevent the waste wiping sponge 320 from falling to the ground. Moreover, in the process of spraying the cleaning liquid, the spilled cleaning liquid will also drip into the waste box 500 along the bottom of the outer sleeve 312 to prevent the cleaning liquid from dripping onto the ground, thereby ensuring the cleanliness of the production environment.

[0052] In some preferred embodiments, a feeding mechanism 600 is further included. The feeding mechanism 600 is located on the side of the outer sleeve 312 away from the steel roller 200. The feeding mechanism 600 includes a material box 610, a push block 620 and a second drive assembly 630 for pushing the push block 620 to translate. The push block 620 is a long structure. The material box 610 is used to carry a plurality of wiping sponges 320. A discharge port and an opening for allowing the push block 620 to pass through are respectively provided on both sides of the material box 610.

[0053] It can be understood that after multiple wiping sponges 320 are placed in the material box 610, the first drive component 330 drives the outer sleeve 312 to rotate so that the empty receiving groove 315 corresponds to the discharge port of the material box 610. Then, the second drive component 630 drives the push block 620 to push the wiping sponge 320 in the material box 610 and approach the outer sleeve 312, so that the wiping sponge 320 is pushed into the receiving groove 315 of the outer sleeve 312. Then, the first drive component 330 drives the outer sleeve 312 to rotate so that the wiping sponge 320 in the receiving groove 315 is transferred to the top of the outer sleeve 312. At this time, the wiping sponge 320 is adsorbed in the receiving groove 315, thereby realizing automatic loading of the wiping sponge 320, reducing the labor intensity of workers and saving labor costs.

[0054] Furthermore, the second driving member includes a crossbeam 631, a base plate 632, a first motor 633, a screw rod 634, a nut 635 and a translation frame 636. The crossbeam 631 is fixed on the frame 100, the base plate 632 is arranged on the crossbeam 631, the first motor 633 is installed on the base plate 632, the two ends of the screw rod 634 are respectively installed on the base plate 632 through two bearing seats 637, the main shaft of the first motor 633 is connected to one end of the screw rod 634, the nut 635 is threadedly connected to the screw rod 634, the translation frame 636 is fixedly connected to the nut 635, the push block 620 is connected to the translation frame 636, a guide rail is arranged on the base plate 632, a slider is slidably connected to the guide rail, the translation frame 636 is fixed on the slider, and the length direction of the guide rail extends along the axial direction of the screw rod 634.

[0055] It can be understood that the first motor 633 drives the screw rod 634 to rotate, and the screw rod 634 drives the nut 635, the translation frame 636 and the slider to translate along the length direction of the guide rail, and the translation frame 636 drives the push block 620 to translate, thereby accurately controlling the moving distance of the push block 620.

[0056] Furthermore, the bottom plate 632 is arranged in the middle of the cross beam 631, two fixed seats 638 are arranged on the cross beam 631, and a guide sleeve 639 is arranged on the fixed seat 638. The two fixed seats 638 are symmetrical along the middle of the cross beam 631, and two guide rods 621 are arranged on the push block 620. The length direction of the guide rod 621 extends along the length direction of the screw rod 634, and the guide sleeve 639 is sleeved on the outer periphery of the guide rod 621.

[0057] It can be understood that during the movement of the push block 620, the push block 620 drives the two guide rods 621 to translate, and the two guide rods 621 slide along the two guide sleeves 639 respectively, thereby ensuring the stability of the push block 620 during translation, so that the wiping sponge 320 can accurately enter the accommodating groove 315.

[0058] In some preferred embodiments, the first drive assembly 330 includes a second motor 331, a reducer 332 connected to the output end of the second motor 331, a connecting shaft 333 transmission-connected to the output end of the reducer 332, and a mounting flange 334 arranged at one end of the connecting shaft 333. One end of the outer sleeve 312 is mounted on the mounting flange 334. The reducer 332 can reduce the output speed of the second motor 331 and increase the output torque, thereby facilitating precise control of the rotation angle of the outer sleeve 312 so that the accommodating groove 315 on the outer sleeve 312 can accurately stay at different corresponding workstations.

[0059] Furthermore, a driving wheel 335 is provided at the output end of the reducer 332, and a driven wheel 336 is provided at the end of the connecting shaft 333 away from the mounting flange 334. The driving wheel 335 and the driven wheel 336 are connected by a belt 337. On the one hand, the stability during the transmission process can be improved and the vibration can be reduced. On the other hand, it can facilitate the arrangement of the motor and the reducer 332 to avoid interference with other components.

[0060] In some preferred embodiments, the spray head 430 includes a universal bamboo tube 431 and a nozzle 432 , one end of the universal bamboo tube 431 is connected to the spray pipe 420 , the nozzle 432 is connected to the other end of the universal bamboo tube 431 , and a flow regulating valve 433 is provided on the universal bamboo tube 431 .

[0061] It can be understood that the universal bamboo tube 431 has the characteristic of free positioning at any angle, and can be bent and positioned at will without any supporting object, so as to facilitate adjustment of the position and direction of the nozzle 432, thereby ensuring that the cleaning liquid can be accurately sprayed onto the corresponding wiping sponge 320 and reducing splashing of the cleaning liquid.

[0062] Furthermore, the universal bamboo tube 431 is a Y-shaped double-ended tube having two liquid outlet ends, and two nozzles 432 are respectively arranged at the two liquid outlet ends, thereby increasing the number of nozzles 432 so that the cleaning liquid can be evenly sprayed on the wiping sponge 320.

[0063] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
