Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of battery production equipment, and specifically relates to a spraying device for alkaline battery production. Background Technology
[0002] Alkaline zinc-manganese batteries are batteries made with zinc as the negative electrode, manganese dioxide as the positive electrode, and sodium hydroxide or potassium hydroxide as the electrolyte, employing a reverse polarity structure. Current manufacturing processes for alkaline zinc-manganese rechargeable batteries involve spraying a conductive emulsion onto the inner surface of the steel casing to reduce the overall battery resistance.
[0003] A search revealed that Chinese Patent CN211637047U discloses a spraying device for the production of alkaline zinc-manganese batteries, comprising a spraying box, a nozzle bracket, a nozzle, and a liquid delivery device. The nozzle bracket is fixedly mounted on the top surface inside the spraying box, and the nozzle is mounted on the bottom surface of the nozzle bracket. The liquid delivery device includes a delivery pipe, a liquid tank, and a pump. The pump delivers liquid from the liquid tank to the nozzle through the delivery pipe. The spraying device also includes a spraying disc with a rectangular mounting groove on its top surface. A placement disc is detachably mounted in the rectangular mounting groove, and a water passage hole penetrating the side of the spraying disc is opened on one side of the bottom surface of the rectangular mounting groove. A placement cavity is provided on the top surface of the placement disc, the diameter of which is larger than the outer diameter of the battery casing. A cross-shaped support structure is provided on the bottom surface of the placement cavity, and the length from the top opening of the placement cavity to the cross-shaped support structure is greater than the length of the battery casing. The cross-shaped support structure consists of mutually perpendicular horizontal and vertical bars.
[0004] As can be seen from the existing technology, during the production process of alkaline batteries, a conductive layer needs to be coated inside the cylindrical steel casing of the battery. This involves spraying graphite conductive liquid onto the inner wall. Existing battery liquid spraying devices generally use conventional nozzles, which can only spray the conductive liquid onto the inner wall and cannot achieve a uniform formation of the conductive liquid layer on the inner wall. This will affect the performance of the battery. Utility Model Content

One end of the support plate 10 is fixedly installed to the lifting seat 704. The screw 702 is driven by the output end of the drive motor 703 to move in the mounting groove 701. Rotation at slot 701 causes the lifting seat 704, threadedly connected to the outer side of screw 702, to slide. The lifting seat 704 then moves the nozzle 15 downwards and inserts it into the battery casing of the battery casing mold 4. Subsequently, the pump 12 distributes the paint from the material box 13 through the main conveying pipe 18 to the conveying branch pipe 14, and then through the conveying branch pipe 14 to the nozzle 15. Engaging the rotating mechanism 16 at the nozzle 15, uniform spraying of the inner wall of the battery casing can be achieved.

The battery casing mold 4 can be easily positioned and placed through the slot 19 on the mold frame 2. Excess paint during the spraying process can be received through the through hole 20 at the slot 19.
[0028] Operating principle and advantages: During use, the output end of the drive motor 703 drives the screw 702 to rotate at the mounting slot 701, causing the lifting seat 704 connected to the outer thread of the screw 702 to slide. The lifting seat 704 drives the nozzle 15 to move down and extend into the battery shell of the battery shell mold 4. Then, the material pump 12 distributes the paint from the material box 13 to the conveying branch pipe 14 through the conveying main pipe 18, and then conveys it to the nozzle 15 through the conveying branch pipe 14. At the same time, the output end of the electric push rod 161 extends and retracts through the push frame 162 to simultaneously link multiple racks 163 to slide. The racks 163 mesh with the toothed ring 164 on the outside of the nozzle 15, allowing the nozzle 15 to rotate on the support plate 10, which facilitates uniform spraying of the inner wall of the battery shell.
[0029] The positioning hole 5 on the battery casing mold 4 allows for easy positioning of the battery casing cylinder. The battery casing mold 4 is inserted into the mold frame 2 on the base plate 1. During the spraying process, the positioning hole 5 is positioned directly above the collection box 3, which allows for easy recycling of some of the paint. After recycling, the collection box 3 can be removed directly, and the paint can be transferred to the material box 13.
