Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a four-axis coating machine. Background Technology

[0002] A coating machine is a key piece of equipment in lead-acid battery production, used to evenly coat lead paste onto the grids. Through a specific coating process, it ensures that the lead paste evenly covers one or both sides of the grids, thereby improving battery performance and quality. The working principle of the coating machine involves precise control of the lead paste pressure and flow rate to achieve continuous and uniform coating of lead paste onto the lead strip surface. Based on the traction method and coating process, coating machines can be divided into wheeled, belt-type, and combined wheeled / belt-type machines. Wheeled coating machines are suitable for high-precision and continuous production, belt-type coating machines are suitable for both large-size grids and intermittent production, while combined wheeled / belt-type machines combine the advantages of both, improving the equipment's versatility and flexibility.

[0003] Existing utility model patent CN221558866U proposes a lead paste extrusion device for coating plates. This utility model arranges an extrusion roller and two agitators within a frame, with a gap-filling component above the agitators. The gap-filling rod of the gap-filling component densifies the gaps between the agitators, making the lead paste subjected to uniform force and improving the uniformity and continuity of paste application.

[0004] As described in the above technical solution, the filling rod densifies the gaps between the mixing components, making the lead paste more uniformly stressed, improving the uniformity and continuity of the paste application, and reducing the problem of uneven paste application caused by the large extrusion stroke. However, the above device has the problem of being difficult to clean. After the coating machine finishes coating, it needs to be cleaned to remove residual lead paste and ensure the efficiency of subsequent production. However, the mixing components, extrusion rollers, and seals of this equipment are all located inside the frame, making the structure complex, the seals easily damaged, and inconvenient to disassemble.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] Please see Figure 1-7 The present application proposes a four-axis coating machine, which includes a receiving hopper 1, a feeding assembly 2, and a scraper assembly 3.

[0054] like Figure 1-2As shown, the feeding assembly 2 includes a feeding hopper 21 and a drive unit 22. The receiving hopper 1 is detachably connected to the top of the feeding hopper 21 for easy disassembly and cleaning; the scraper assembly 3 is detachably connected to the bottom of the feeding hopper 21, also for easy disassembly. The roller section includes a feeding shaft 23, a paste-coating roller 24, and a paste-discharging roller 25. There are two feeding shafts 23, parallel to each other on the top of the feeding hopper 21 and located below the receiving hopper 1, with their ends installed at mounting positions on the top of the feeding hopper 21 for lead paste mixing. The paste-discharging roller 25 is inserted into the feeding hopper 21 through an insertion position on the side wall of the feeding hopper 21 and is located above the scraper assembly 3, parallel to the feeding shafts 23, for discharging lead paste. The paste-coating roller 24 is installed at the bottom of the feeding hopper 21 and parallel to the feeding shafts 23, with its ends located at mounting positions at the bottom of the feeding hopper 21, for extruding lead paste. The drive unit 22 is installed on the outside of the side wall of the feeding hopper 21 and is driven to connect with the feeding shaft 23, the paste roller 24 and the paste roller 25.

[0055] Specifically, the receiving hopper 1 is fixed in the working area. When the equipment is running, the drive component 22 drives the feeding shaft 23 to rotate, thereby stirring the lead paste placed in the receiving hopper 1. The two feeding shafts 23 are parallel and staggered vertically. The upper feeding shaft 23 first stirs the lead paste, while the lower feeding shaft 23 stirs the pre-treated lead paste again. The dual stirring method makes the distribution of lead paste more uniform, creating better conditions for the subsequent coating process and further improving the uniformity and moisture content consistency of the lead paste. The lower paste roller 25, together with the coating roller 24, transports the stirred lead paste to the scraper assembly 3, and finally the scraper assembly 3 sprays the paste evenly onto the grid.

[0056] When disassembly and cleaning are required, the detachable design of the receiving hopper 1 and the scraper assembly 3 allows them to be quickly removed for easy cleaning. The feeding shaft 23 and the paste-coating roller 24 can be removed from their respective installation positions, while the lower paste roller 25 can be pulled out from its insertion position, significantly improving the ease of cleaning the coating machine, facilitating thorough cleaning, and enhancing the cleaning efficiency and quality of the equipment. Simultaneously, during operation, since the receiving hopper 1 and the scraper assembly 3 are respectively located at the top and bottom of the lower hopper 21, their installation positions can be sealed and fixed, ensuring stability after installation.

[0057] In some embodiments, such as Figure 4-5As shown, the feeding shaft 23 consists of a rotating shaft 231, a first bearing seat 232, and a first sealing plate 233. The rotating shaft 231 is installed on the top of the feeding hopper 21. First mounting grooves 101 are symmetrically opened at both ends of the top sidewall of the feeding hopper 21 for mounting the two ends of the rotating shaft 231. There are two first bearing seats 232, detachably connected to the two first mounting grooves 101 on the outer sidewall of the feeding hopper 21. The two ends of the rotating shaft 231 pass through the corresponding first bearing seats 232 and are rotatably connected to them to ensure stable rotation of the rotating shaft 231. There are two first sealing plates 233, respectively located on both sides of the outer sidewall of the feeding hopper 21 between the corresponding first bearing seats 232, and detachably connected to the feeding hopper 21. The first sealing plates 233 have clearance holes corresponding to the rotating shaft 231 to prevent lead paste leakage and maintain the cleanliness of the equipment interior.

[0058] Specifically, when disassembly or maintenance is required, simply remove the first bearing housing 232 and the first sealing plate 233 to easily remove the feeding shaft 23 upwards from the first mounting groove 101; installation is the reverse. This makes disassembly and assembly of the feeding shaft 23 very convenient, facilitating subsequent cleaning and maintenance. It effectively solves the problem of the feeding shaft 23 being difficult to disassemble and clean in traditional equipment, improving the maintenance efficiency and cleaning quality of the equipment. At the same time, the first bearing housing 232, in conjunction with the first sealing plate 233, ensures its stability after installation, thereby ensuring the smooth progress of the coating process and the stability of the coating quality.

[0059] In some embodiments, such as Figure 6 As shown, the feeding shaft 23 also includes feeding rods 234. Two feeding rods 234 are fixedly mounted in the middle of the rotating shaft 231 and are arranged parallel to the rotating shaft 231. The two feeding rods 234 are located on both sides of the rotating shaft 231 and are staggered. This staggered arrangement of feeding rods 234 can fully agitate and stir the lead paste when the rotating shaft 231 rotates.

[0060] Specifically, during operation, the feeding rod 234 rotates with the rotating shaft 231, agitating and stirring the lead paste. Because the feeding rod 234 is staggered, it can fully agitate and stir the lead paste, resulting in a more uniform distribution. This provides higher-quality raw materials for subsequent coating processes, improving coating uniformity. This optimizes the lead paste pretreatment process, improves the quality of the final coated product, reduces coating defects caused by uneven lead paste distribution, and enhances product performance and consistency.

[0061] In some embodiments, such as Figure 4-5As shown, the paste-applying roller 24 includes a first roller body 241, a second bearing seat 242, and a second sealing plate 243. The first roller body 241 is installed at the bottom of the feed hopper 21. Second mounting grooves 102 are symmetrically opened at both ends of the opposite sidewall of the bottom of the feed hopper 21 for mounting the first roller body 241. There are two second bearing seats 242, detachably connected to the two second mounting grooves 102 on the outer sidewall of the feed hopper 21. The two ends of the first roller body 241 pass through the corresponding second bearing seats 242 and are rotatably connected to them to ensure stable rotation of the first roller body 241. There are two second sealing plates 243, respectively located on both sides of the outer sidewall of the feed hopper 21 between the corresponding second bearing seats 242, and detachably connected to the feed hopper 21. The second sealing plates 243 have clearance holes corresponding to the first roller body 241 to prevent lead paste leakage.

[0062] Specifically, when disassembly or maintenance is required, simply remove the second bearing housing 242 and the second sealing plate 243 to easily remove the coating roller 24 downwards from the second mounting slot 102; installation is the reverse. This makes disassembly and assembly of the coating roller 24 very convenient, facilitating subsequent cleaning and maintenance. It effectively solves the problem of difficulty in disassembling and cleaning the coating roller 24 in traditional equipment, improving equipment maintenance efficiency and cleaning quality. Simultaneously, the second bearing housing 242, in conjunction with the second sealing plate 243, ensures stability after installation, thereby guaranteeing the smooth progress of the coating process and the stability of the coating quality.

[0063] In some embodiments, such as Figure 4-5 As shown, the paste roller 25 includes a second roller body 251, a third bearing seat 252, and a third sealing plate 253. The second roller body 251 is located in the middle of the feeding hopper 21. The sidewalls of the feeding hopper 21 have symmetrical insertion holes 103 corresponding to the second roller body 251 for insertion. The second roller body 251 is arranged parallel to the paste roller 24 to assist in the transfer of lead paste from the receiving hopper 1 to the paste roller 24. There are two third bearing seats 252, detachably connected to the two insertion holes 103 on the outer sidewalls of the feeding hopper 21. Both ends of the second roller body 251 pass through the corresponding third bearing seats 252 and are rotatably connected to them to ensure stable rotation of the second roller body 251. There are two third sealing plates 253, which are respectively located on the outer sides of the side wall of the hopper 21 and between the corresponding insertion holes 103, and are detachably connected to the hopper 21. The third sealing plate 253 has an avoidance hole at the location corresponding to the second roller body 251 to prevent lead paste leakage.

[0064] Specifically, when disassembly or maintenance is required, simply remove the third bearing housing 252 and the third sealing plate 253, and the second roller body 251 can be directly pulled out from the insertion hole 103; installation is the reverse. This makes the disassembly and assembly of the lower paste roller 25 very convenient, facilitating subsequent cleaning and maintenance. It effectively solves the problem of the lower paste roller 25 being difficult to disassemble and clean in traditional equipment, improving the maintenance efficiency and cleaning quality of the equipment. At the same time, the fixing of the third bearing housing 252 in conjunction with the third sealing plate 253 ensures its stability after installation, thereby ensuring the smooth progress of the coating process and the stability of the coating quality.

[0065] In some embodiments, such as Figure 1-3 As shown, the drive unit 22 includes a first gear 221, a second gear 222, a drive motor 223, and a linkage 224. The two first gears 221 are respectively mounted on the same side of the coating roller 24 and the lower coating roller 25 outside the feeding hopper 21, and the two first gears 221 mesh with each other to ensure synchronous rotation of the coating roller 24 and the lower coating roller 25. The two second gears 222 are respectively mounted on the same side of the two feeding shafts 23 outside the feeding hopper 21, and the two second gears 222 mesh with each other, allowing the lower coating roller 25 to rotate relative to the coating roller 24, facilitating stable feeding of lead paste. Simultaneously, the second gears 222 and the first gears 221 are located on opposite sides of the feeding hopper 21, enabling power transmission from both sides.

[0066] The drive motor 223 is installed on one side of the hopper 21 corresponding to the first gear 221 and is driven by one of the corresponding first gears 221 to provide power to the equipment. The linkage 224 includes a sprocket 2241 and a chain 2242. The two sprockets 2241 are respectively installed on the outer wall of one of the second gears 222 and the corresponding ends of the lower roller 25. The chain 2242 is sleeved on the two sprockets 2241 and is used to drive the second gear 222 to rotate.

[0067] Specifically, during operation, the drive motor 223 drives the lower paste roller 25 to rotate via the first gear 221. The rotation of the lower paste roller 25 ensures the synchronous rotation of the coating roller 24 through the meshing of the first gear 221. Simultaneously, the chain 2242 in the linkage 224 rotates under the drive of the sprocket 2241, transmitting the rotational power of the lower paste roller 25 to the second gear 222, which in turn drives the feeding shaft 23 to rotate, achieving simultaneous drive from both sides. This not only improves the efficiency of power transmission, ensuring smoother operation of the entire equipment and reducing malfunctions caused by insufficient power or poor transmission, but also ensures the coating machine operates stably and efficiently, meeting production needs. Furthermore, this dual-sided configuration facilitates later maintenance and replacement, improving the maintainability and operational stability of the equipment, and reducing maintenance costs and downtime. Through this optimized power transmission system, the long-term stable operation of the equipment is guaranteed, and production efficiency and economic benefits are significantly improved.

[0068] In some embodiments, such as Figure 5 , Figure 7 As shown, the scraper assembly 3 includes a baffle plate 31, a lower scraper roller 32, and a coating roller scraper 33. The baffle plate 31 is detachably connected to the bottom of the feed hopper 21, and has a discharge port 104 at its center corresponding to the coating roller 24 for controlling the output of lead paste. The lower scraper roller 32 is fixedly mounted on the top of the baffle plate 31 and located on one side of the coating roller 24, extending into the lower feed hopper 21 to the bottom of the lower scraper roller 25, for scraping off the lead paste from the surface of the lower scraper roller 25. The coating roller scraper 33 is fixedly mounted on the top of the baffle plate 31 and located on the other side of the coating roller 24, for scraping off the lead paste from the surface of the coating roller 24.

[0069] Specifically, during operation, the lower paste roller scraper 32 and the coating roller scraper 33 respectively scrape off the lead paste from the surfaces of the lower paste roller 25 and the coating roller 24, ensuring that the lower paste roller 25 delivers lead paste evenly downwards each time, guaranteeing the amount of lead paste delivered downwards, thereby ensuring coating quality. When cleaning or maintenance is required, the baffle plate 31 can be quickly removed. At the same time, the lower paste roller scraper 32 and the coating roller scraper 33, which are fixed on the baffle plate 31, can be removed and cleaned together, facilitating the cleaning and maintenance of the scraper assembly 3. This significantly improves the ease of cleaning the coating machine, allowing for thorough cleaning, improving the cleaning efficiency and quality of the equipment, thereby extending the service life of the equipment and ensuring coating quality.
