Description

Technical Field

[0001] This invention belongs to the field of lead-acid battery plate manufacturing technology, and in particular relates to a paste coating system for lead-acid battery plates used in energy storage production. Background Technology

[0002] The electrode paste coating system refers to the entire set of key equipment and process lines used in the manufacturing process of lead-acid batteries to coat lead paste onto the grid to form positive and negative electrode plates. It is one of the core steps in lead-acid battery production, directly determining the quality, consistency, and final battery performance of the electrode plates. Typically, after the paste coating is completed, the wet electrode plate surface needs to be treated by acid leaching / immersion to form a layer of lead sulfate on the electrode plate surface. This facilitates rapid and uniform drying, prevents cracking, and improves initial capacity. Traditional acid immersion involves manually loading the electrode plates into an acid immersion tank, which is then placed in the tank for reaction. This method is unsuitable for acid immersion treatment of electrode plates produced through continuous casting, rolling, and coating. Summary of the Invention

[0003] The purpose of this invention is to provide a plate paste coating system for the production of energy storage lead-acid batteries. Through the optimized layout of the guide roller, feed roller and discharge roller, the plate belt runs stably in the acid immersion tank, reducing deviation and slippage, ensuring uniform application of lead paste, improving the consistency of battery performance, and solving the problems mentioned in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a plate coating system for the production of energy storage lead-acid batteries, comprising an acid immersion tank, inside which a guide roller is installed, and an infeed guide roller and an outlet guide roller are respectively installed on both sides of the guide roller. In use, the plate strip after coating is controlled to pass sequentially through the infeed guide roller, the guide roller, and the outlet guide roller; both the infeed guide roller and the outlet guide roller are higher than the top surface of the acid immersion tank; scraper A and scraper B are respectively installed between the guide roller and the outlet guide roller to remove residual acid from the upper and lower surfaces of the plate strip; scraper B is located between scraper A and the outlet guide roller; this achieves continuous acid immersion processing, with the scraper automatically removing residual acid from the surface of the plate strip, solving the problem of traditional continuous production.

[0006] Furthermore, it also includes a base plate, on the upper surface of which four L-shaped columns are fixed, and a rectangular frame is fixed to the top of the four columns; the four corner sides of the pickling tank are respectively fitted into the inner walls of the four columns; a drive mechanism for driving the pickling tank to move up and down is installed on the upper surface of the base plate. The modular design allows the pickling tank to be raised and lowered, which facilitates the adjustment of the length of the electrode strip immersed below the liquid surface of the pickling tank according to the needs during use, thereby adjusting the pickling time of the electrode strip.

[0007] Furthermore, a pair of fixed seats are respectively provided on the upper surfaces of both ends of the rectangular frame, and both ends of the feed guide roller and the discharge guide roller are installed on the fixed seats; a horizontal bar is connected to both of the opposite inner walls of the rectangular frame, and the end of the horizontal bar is connected to a vertical bar, and both ends of the guide roller are respectively installed on the two vertical bars.

[0008] Furthermore, the driving mechanism includes a lifting cylinder mounted on the upper surface of the base plate, and the end of the lifting cylinder abuts against the outer bottom side of the pickling tank.

[0009] Furthermore, both scraper A and scraper B are scraper bodies made of rubber or plastic with a triangular cross-section. The flexible material avoids damage to the electrode plate, and the triangular cross-section enhances the acid scraping efficiency.

[0010] Furthermore, the scraper A is fixed on a horizontal plate A, and both ends of the horizontal plate A are respectively connected to an L-shaped frame A. An elastic telescopic member A is connected between the horizontal section and the rectangular frame of the L-shaped frame A. The scraper B is fixed on a horizontal plate B, and both ends of the horizontal plate B are respectively connected to an L-shaped frame B. An elastic telescopic member B is connected between the horizontal section and the rectangular frame of the L-shaped frame B. The elastic telescopic members A and B can adapt to the fluctuation of the electrode plate thickness, ensuring that the scraper always fits the surface.

[0011] Furthermore, the elastic telescopic components A and B have the same structure, both including an inner sleeve, an outer sleeve, and a spring connected between them; in the use state, the spring of elastic telescopic component A is in a stretched state, and the spring of elastic telescopic component B is in a compressed state; the elastic telescopic component A of scraper A provides downward pressure in the stretched state, and the elastic telescopic component B of scraper B provides upward thrust in the compressed state, forming a bidirectional clamping scraping.

[0012] Furthermore, the vertical section and the horizontal plate A of the L-shaped frame A are connected by a connecting structure A, and the vertical section and the horizontal plate B of the L-shaped frame B are connected by a connecting structure B. The connecting structures A and B are identical. The connecting structure A includes a rectangular hole on the side wall of the vertical section of the L-shaped frame A and a rectangular block at the end of the horizontal plate A that is inserted into the rectangular hole. The bottom end of the vertical section of the L-shaped frame A is threaded with an adjusting bolt A whose end abuts against the bottom side of the rectangular block. The end of the rectangular block is threaded with a disc nut that abuts against the side wall of the vertical section of the L-shaped frame A through a stud, which facilitates adjustment of the installation height of scraper A and scraper B and the gap between them during use.

[0013] Furthermore, both the horizontal plate A and the horizontal plate B include a base plate, on which a dovetail groove for mounting the scraper body is formed. Limiting blocks are fixed to both ends of the dovetail groove by bolts. A threaded hole is provided on the bottom side of the dovetail groove, and an adjusting bolt B with its end abutting against the scraper body is threaded onto the threaded hole, which facilitates quick disassembly and assembly of the scraper and adjustment of the scraper pressure.

[0014] The present invention has the following beneficial effects:

[0015] This invention optimizes the layout of the guide roller, feed roller, and discharge roller, ensuring stable operation of the grid belt in the acid immersion tank, reducing deviation and slippage, ensuring uniform application of lead paste, improving battery performance consistency, and facilitating the removal of residual acid through the setting of scraper A and scraper B.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0026] Example 1:

[0027] Please see Figure 1-3 As shown, this invention is a plate coating system for the production of energy storage lead-acid batteries. In use, a base plate 1 is fixed to the ground, and four rectangular L-shaped columns 11 are installed on the upper surface of the base plate 1. A rectangular frame 12 is fixed to the top of the four columns 11, and a lifting cylinder 10 is installed on the upper surface of the base plate 1 to drive the acid immersion tank 2 to move up and down. The end of the lifting cylinder 10 abuts against the outer bottom side of the acid immersion tank 2, and the four corner sides of the acid immersion tank 2 are respectively fitted into the inner walls of the four columns 11. In use, the coated plate strip 100 is controlled to pass through the interior of the acid immersion tank 2.

[0028] Specifically, a pair of fixed seats 13 are respectively set on the upper surface of both ends of the rectangular frame 12, and feed guide rollers 15 and discharge guide rollers 14 are respectively installed at both ends of the rectangular frame 12 through the fixed seats 13. At the same time, crossbars 20 are connected to the two opposite inner walls of the rectangular frame 12, and vertical bars 22 are connected to the ends of the crossbars 20. A guide roller 21 is connected between the bottom ends of the two vertical bars 22. The guide roller 21 is located below the liquid surface inside the acid immersion tank 2. Thus, during use, the electrode belt 100 that has completed the coating of paste passes through the feed guide roller 15, the guide roller 21 and the discharge guide roller 14 in sequence to complete the acid immersion.

[0029] Specifically, the feed guide roller 15 and the discharge guide roller 14 are both higher than the top surface of the acid immersion tank 2; scraper A41 and scraper B31 are respectively arranged between the feed guide roller 21 and the discharge guide roller 14 to scrape off the residual acid on the upper and lower surfaces of the electrode belt 100; scraper B31 is located between scraper A41 and discharge guide roller 14.

[0030] Based on the above, the scraper A41 and scraper B31 provided by the present invention are both scraper bodies 400 made of rubber with a triangular cross-section. Scraper A41 and scraper B31 are detachably installed on horizontal plate A4 and horizontal plate B3, respectively. The two ends of horizontal plate A4 are respectively connected to L-shaped frame A42, and the two ends of horizontal plate B3 are respectively connected to L-shaped frame B32. L-shaped frame A42 and L-shaped frame B32 are respectively connected to rectangular frame 12 through vertically arranged elastic telescopic members A43 and B33. The setting of elastic telescopic members A43 and B33 can ensure that the scraper is in close contact with the electrode plate belt. The lifting cylinder 10 adjusts the acid immersion depth and thus adjusts the acid immersion time. Scraper A41 and scraper B31 can automatically scrape off residual acid.

[0031] Specifically, elastic telescopic components A43 and B33 have the same structure, both including an inner sleeve, an outer sleeve, and a spring connected between them; when in use, the spring of elastic telescopic component A43 is in a stretched state, and the spring of elastic telescopic component B33 is in a compressed state.

[0032] Example 2, based on Example 1, such as Figure 4To facilitate adjustment of the installation height and gap width between scrapers A41 and B31 during use, a connecting structure A is used to connect the vertical section of L-shaped frame A42 and the horizontal plate A4, and a connecting structure B is used to connect the vertical section of L-shaped frame B32 and the horizontal plate B3. The connecting structures A and B are identical. The connecting structure A includes a rectangular hole 421 on the side wall of the vertical section of L-shaped frame A42 and a rectangular block 401 at the end of the horizontal plate A4, which is inserted into the rectangular hole 421. The bottom end of the vertical section of L-shaped frame A42 is threaded with an adjusting bolt A422 whose end abuts against the bottom side of the rectangular block 401. The end of the rectangular block 401 is threaded with a disc nut 402 that abuts against the side wall of the vertical section of L-shaped frame A42 through a stud 403.

[0033] Meanwhile, in order to facilitate the replacement of scraper A41 and scraper B31 during use, the horizontal plate A4 and horizontal plate B3 provided by the present invention both include a base plate. The base plate is provided with a dovetail groove 301 for mounting the scraper body 400. The two ends of the dovetail groove 301 are respectively fixed with limit blocks 303 by bolts 302. The bottom side of the dovetail groove 301 is provided with a threaded hole, and an adjusting bolt B304 with its end abutting against the scraper body 400 is threadedly connected to the threaded hole.
