Description

Technical Field

[0001] This utility model relates to the field of alkaline zinc-manganese battery technology, and in particular to a spraying device for alkaline zinc-manganese batteries. Background Technology

[0002] Alkaline zinc-manganese batteries are batteries with zinc as the negative electrode, manganese dioxide as the positive electrode, and sodium hydroxide or potassium hydroxide as the electrolyte, using a reverse polarity structure. They consist of a positive electrode, a negative electrode, and an electrolyte. The positive electrode (cathode) is a mixture of manganese dioxide, graphite (to enhance conductivity), and potassium hydroxide electrolyte. The battery's outer casing, usually a steel cylinder, serves as the positive terminal and is in contact with the positive electrode material. The negative electrode (anode) is powdered zinc mixed with a gel-like electrolyte to form a paste, located in the center of the battery. The electrolyte is a highly concentrated potassium hydroxide solution, alkaline (hence the name), with better conductivity than ammonium chloride or zinc chloride.

[0003] In the production of alkaline zinc-manganese batteries, spraying is a key process, mainly used for insulation, rust prevention, lubrication, and marking. During long-term storage or under harsh conditions, the highly alkaline electrolyte may still corrode the inner wall of the battery's steel casing. Spraying an additional anti-corrosion coating on the inner wall can greatly improve the battery's leak-proof capability and storage life. Therefore, a spraying device for alkaline zinc-manganese batteries is proposed. Utility Model Content

[0016] Example: Refer to Figure 1-4 A spraying device for alkaline zinc-manganese batteries includes a spraying frame 1. A push plate 24 is mounted on the spraying frame 1 via a displacement component. Two placement frames 3 are mounted on the push plate 24, and battery steel shells 6 are placed on the placement frames 3. A spraying assembly is provided on the spraying frame 1. The spraying assembly includes a bracket 7 fixedly mounted on the spraying frame 1. A telescopic cylinder 8 is fixedly mounted on the bracket 7. The output end of the telescopic cylinder 8 is connected to a rotary motor 9. The output end of the rotary motor 9 is connected to a spraying pipe 10. The spraying pipe 10 is provided with multiple nozzles 12 and is located in the middle of the battery steel shell 6. An external pipe 11 is connected to one side of the spraying pipe 10. The battery steel shell 6 to be sprayed is placed in the placement frame. 3. Then, start the telescopic cylinder 8 to drive the spray pipe 10 to move down. After the spray pipe 10 moves down, it will be located in the middle of the battery steel shell 6. The outer pipe 11 is connected to the external paint box. The paint is delivered into the spray pipe 10 through the pump. The outer pipe 11 is a rubber tube. The rotary motor 9 drives the spray pipe 10 to rotate. The rotary motor 9 can be a stepper motor. It rotates only once each time and returns to its original position after rotation. Through forward and reverse spraying, the inner wall of the battery steel shell 6 can be effectively and evenly sprayed with anti-corrosion coating. A storage groove 13 is opened on one side of the placement frame 3. A drop hole 17 is opened on the top inner wall of the storage groove 13. The placement frame 3 is equipped with a bottom scraping component.

[0017] Specifically, the displacement assembly includes a guide post 4 fixedly installed on the spray frame 1, a guide block 5 fixedly installed at the bottom of the push plate 24, the guide block 5 slidingly sleeved on the guide post 4, a push cylinder 2 fixedly installed on the side of the spray frame 1, and the output end of the push cylinder 2 connected to the side of the push plate 24. After the spraying is completed, the spray pipe 10 moves upward, the battery steel shell 6 is removed, and then the push cylinder 2 is started to drive the push plate 24 to move. The movement of the push plate 24 drives the placement frame 3 to move. One placement frame 3 will move to one side, and the other placement frame 3 will be located below the spraying position. The guide post 4 and the guide block 5 can limit the horizontal position of the movement of the placement frame 3.

[0018] Specifically, the bottom scraping assembly includes a set of push columns 19 movably mounted on the placement frame 3. A push scraper 18 is fixedly mounted at one end of each push column 19, located inside the placement frame 3. An arc-shaped extrusion block 20 is fixedly mounted at the other end of each push column 19. A compression spring 21 is fixedly mounted between the arc-shaped extrusion block 20 and the side of the placement frame 3. An inclined guide column 22 is fixedly mounted on the top of the spray frame 1. A horizontal extrusion column 23 is fixedly mounted on one side of the inclined guide column 22. The arc-shaped extrusion block 20 is adapted to the inclined guide column 22 and the horizontal extrusion column 23. A storage box 14 is installed inside the storage slot 13. One side of the storage box 14 extends to the outside of the placement frame 3. A first magnetic block 15 is fixedly mounted on the side of the placement frame 3, and a second magnetic block 16 is fixedly mounted on the side of the storage box 14. The first magnetic block 15 and the second magnetic block 16 are attracted by opposite poles. During the movement of the placement frame 3, the arc-shaped extrusion block 20 will be driven... The curved extrusion block 20 moves, first contacting the inclined guide column 22. After contact, it is squeezed, and the movement of the curved extrusion block 20 drives the push column 19 to move, thereby driving the push scraper 18 to move. The bottom of the push scraper 18 contacts the bottom of the placement frame 3, which can scrape the excess paint from the previous spraying process to one side. As it moves continuously, the curved extrusion block 20 will be located inside the horizontal extrusion column 23. At this time, the push scraper 18 will be located above the drop hole 17. The scraped excess paint will be located in the collection box 14, realizing the collection operation. When a lot of paint is collected, the collection box 14 is pulled outward, and the first magnetic block 15 and the second magnetic block 16 separate. The collection box 14 can then be taken out to process and reuse the collected paint. By moving back and forth, it is convenient to automatically scrape the excess paint on the placement frame 3 without affecting the next battery steel shell 6 placement and spraying operation.

[0019] In use: During the production of alkaline zinc-manganese batteries, the interior of the battery steel shell 6 needs to be coated with an anti-corrosion spray. The battery steel shell 6 to be coated is placed on the placement frame 3. The telescopic cylinder 8 is activated to move the spray pipe 10 downward. The paint is delivered into the spray pipe 10 through an external pump. The rotary motor 9 drives the spray pipe 10 to rotate, performing rotary spraying, which can effectively and evenly coat the inner wall of the battery steel shell 6 with an anti-corrosion spray. After the spraying is completed, the spray pipe 10 is moved upward. The push cylinder 2 is activated to move the push plate 24. During the movement of the placement frame 3, the arc-shaped extrusion block 20 moves. The arc-shaped extrusion block 20 extrudes and moves, which in turn moves the push scraper 18, which can scrape the excess paint from the previous spraying process to one side. The scraped excess paint will be placed in the collection box 14 for collection. By moving back and forth, it is easy to automatically scrape the excess paint on the placement frame 3 without affecting the next battery steel shell 6 placement and spraying operation, making it convenient to use.
