[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In this invention, the cooperation between the material cylinder and the material pump, as well as the material extraction pipe and the spray pipe, facilitates the coating of the lithium battery electrode sheet to be sprayed out from each nozzle in the material cylinder. The coating can be leveled by the brush roller. The cooperation between the U-shaped plate II, the U-shaped rod I, the spring and the material collection frame facilitates the close contact between the cleaning plate and the brush roller. Then, when the brush roller rotates, the coating adhering to its surface can be scraped off, so that the coating can fall into the material collection frame. The coating can be easily reintroduced into the material cylinder through the discharge hose, avoiding waste of coating and thus avoiding uneven coating caused by coating adhering to the brush roller.

[0017] (2) The invention facilitates the horizontal movement of the two screw nuts through the cooperation between the motor and the bidirectional screw, as well as the guide block and the guide rod. It also facilitates the limiting of the top plate through the cooperation between the U-shaped round rod and the lifting plate and the top rod, so that the top plate can only move up and down. The movable rod facilitates the descent of the top plate, thereby facilitating the brush roller to descend and level the coating.

[0018] (3) The invention facilitates the rotation of the stirring rod 2 through the cooperation between the motor 2 and the stirring shaft, and facilitates the rotation of the top cylinder through the cooperation between the driving gear and the driven gear, the driven shaft and the conveyor belt, and facilitates the rotation of the two scrapers through the cooperation between the connecting rod 1 and the scraper, and the connecting rod 2 and the support column, so as to scrape off the paint adhering to the inner wall of the material cylinder, thereby facilitating the subsequent cleaning of the inside of the material cylinder. At the same time, it makes the stirring rod 1 rotate. Since the rotation direction of the stirring rod 1 and the stirring rod 2 is opposite, it is convenient to fully stir the paint in the material cylinder to avoid solidification and agglomeration.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1-6 The present invention includes a frame 1, on which transmission rollers 5 are mounted at equal angles, a cleaning mechanism 2 is mounted on the frame 1, and an adjustment mechanism 3 and a stirring mechanism 4 are mounted on the cleaning mechanism 2.

[0030] In Embodiment 2, based on Embodiment 1, the cleaning mechanism 2 includes a U-shaped frame 201 fixed to the top of the frame 1. A U-shaped frame 202 is provided on the inner side of the U-shaped frame 201. A brush roller 2013 is rotatably connected inside the U-shaped frame 202. A U-shaped round rod 2016 is fixedly installed on the outer side of the U-shaped frame 202. A U-shaped plate 2014 is movably sleeved on the outer side of the U-shaped round rod 2016. Two U-shaped plates 2014 and the U-shaped frame 202 are symmetrically fixedly connected. Two springs 2015 are sleeved on the outside of the first U-shaped round rod 2016. A collection frame 2018 is fixedly installed on the second U-shaped plate 2014. An inclined plate 2022 is fixedly installed inside the collection frame 2018. A cleaning plate 2021 that fits against the brush roller 2013 is fixedly installed on the collection frame 2018. A sleeve plate 2017 is fixedly sleeved on the outside of the first U-shaped round rod 2016. The collection frame 2018 is located between the brush roller 2013 and the sleeve plate 2017. Between 17, a support plate 2019 is fixedly connected between the sleeve plate 2017 and the U-shaped frame 202. A limiting wheel 2020 is provided on the U-shaped plate 2014, located on the top of the support plate 2019. A base 208 is fixedly installed on the frame 1, and a material cylinder 205 is fixedly installed on the top of the base 208. The top of the material cylinder 205 has an opening 209, and a feed pipe 204 is fixedly installed on the outside of the material cylinder 205. The material cylinder 205 and the material collection... A discharge hose 203 is fixedly connected between the frames 2018. A material pump 207 is fixedly installed on the outside of the material cylinder 205. The material pump 207 is fixed to the top of the base 208. A U-shaped plate 2011 is fixedly installed on the outside of the U-shaped frame 202. A spray pipe 2012 is fixedly installed on the inside of the U-shaped plate 2011. Nozzles 2010 are provided at equal intervals on the bottom end face of the spray pipe 2012. A suction pipe 206 is fixedly connected between the spray pipe 2012 and the material pump 207.

[0031] Initially, both springs 2015 are stretched. The elastic force of the two springs ensures that the cleaning plate 2021 and brush roller 2013 are tightly fitted together. Simultaneously, the cooperation between the limiting wheel 2020 and the support plate 2019 provides support for the collection frame 2018. First, the paint is injected into the material cylinder 205 through the feed pipe 204. Then, the lithium battery electrode is placed on the transmission roller 5 for conveying. Next, the material pump 207 is started to extract the paint from the material cylinder 205. Simultaneously, the paint enters the spray nozzle 20 through the extraction pipe 206. Within 12, the paint is sprayed from each nozzle 2010 to coat the lithium battery electrode. Then, the brush roller 2013 descends to level the paint. While the brush roller 2013 is rotating, the cleaning plate 2021 scrapes off the paint adhering to its surface to prevent uneven coating caused by paint adhering to the brush roller 2013. The scraped paint falls into the collection frame 2018, and then the paint is guided by the inclined plate 2022 to re-enter the material cylinder 205 through the discharge hose 203. Finally, the paint is reused to avoid waste.

[0032] In embodiment three, based on embodiment one, the adjusting mechanism 3 includes a top plate 301 fixed to the top of the U-shaped frame 202. Two U-shaped rods 3012 are symmetrically fixedly installed on the top of the top plate 301. Both U-shaped rods 3012 penetrate the U-shaped frame 201 and are movably connected to it.

The L-shaped seat 305 is fixed to the outside of the U-shaped frame 201. Two nuts 303 are symmetrically threaded on the outside of the double-acting screw 302. Both nuts 303 are located on the inside of the U-shaped frame 201. Two movable rods 304 are symmetrically rotatably connected to the top of the top plate 301. The ends of the two movable rods 304 away from the top plate 301 are rotatably connected to the bottom of the two nuts 303 respectively. A guide rod 3011 located above the double-acting screw 302 is fixedly installed on the inside of the U-shaped frame 201. Two guide blocks 307 are symmetrically movably sleeved on the outside of the guide rod 3011. The two guide blocks 307 are fixed to the top of the two nuts 303 respectively.

[0033] First, start motor 306 to drive the rotation of bidirectional lead screw 302. Since the two guide blocks 307 are movably sleeved on the outside of guide rod 3011, the two lead screw nuts 303 move horizontally. Then, the top plate 301 moves longitudinally through the two movable rods 304. At the same time, the lifting plate 308 slides along the top rod 3010 through the two U-shaped round rods 3012 to ensure the stability of the top plate 301 when it moves. It also drives the U-shaped frame 202 to move longitudinally. Finally, it drives the brush roller 2013 to descend to level the paint.

[0034] In Example 4, based on Example 1, the stirring mechanism 4 includes an L-shaped base 401 fixed to the top of the cylinder 205. A motor 402 is fixedly mounted on the L-shaped base 401, and a stirring shaft 409 is fixedly mounted on the motor 402. A support column 408 is rotatably connected to the inner bottom wall of the cylinder 205. The bottom end of the stirring shaft 409 passes through the opening 209 and is rotatably connected to the support column 408. Stirring rods 406, all located inside the cylinder 205, are fixedly mounted at equal intervals on the outer side of the stirring shaft 409. Two connecting rods 407 are symmetrically fixedly connected to the outer side of the support column 408. Scraper rods 4010 are fixedly connected to the ends of the two connecting rods 407 away from the support column 408. Both scraper rods 4010 are in contact with the inner wall of the cylinder 205, and the sides of the two scraper rods 4010 that are close to each other are equidistant. A stirring rod 405 is fixedly installed. A top cylinder 4011 is provided inside the opening 209. A connecting rod 404 is fixedly connected between the two scraper rods 4010 and the top cylinder 4011. A bearing 403 is fixedly installed inside the opening 209 and is sleeved on the outside of the top cylinder 4011. The stirring shaft 409 passes through the top cylinder 4011 and is rotatably connected to the top cylinder 4011. A driven shaft 4014 is rotatably connected between the L-shaped seat 401 and the material cylinder 205. A transmission wheel is provided on the outside of both the driven shaft 4014 and the top cylinder 4011. A conveyor belt 4012 is connected between the two transmission wheels. A driven gear 4013 is fixedly installed on the outside of the driven shaft 4014. A driving gear 4015 is fixedly installed on the outside of the stirring shaft 409. The driving gear 4015 and the driven gear 4013 are meshed together.

[0035] First, start motor 2 402, which drives the stirring shaft 409 to rotate, and drives the stirring rod 2 406 to rotate to stir the paint in the barrel 205. At the same time, it drives the drive gear 4015 to rotate. Since the drive gear 4015 is meshed with the driven gear 4013, it drives the driven shaft 4014 to rotate. Then, the conveyor belt 4012 drives the top cylinder 4011 to rotate. With the cooperation between the support column 408 and the connecting rod 2 407, as well as the scraper 4010 and the connecting rod 1 404, the two scrapers 4010 are driven to rotate to scrape off the paint adhering to the inner wall of the barrel 205, which facilitates the cleaning of the inside of the barrel 205 later. At the same time, the stirring rod 1 405 rotates to stir the paint. The rotation direction of the stirring rod 1 405 is opposite to that of the stirring rod 2 406. Finally, the paint is fully stirred to prevent it from solidifying and clumping.
