Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a powder-removing device for cleaning residual floating dust from the positive electrode of a battery. Background Technology

[0002] In traditional alkaline battery production, the positive electrode consists of a steel casing and a manganese ring, which is formed by pressing positive electrode powder using a pressure molding machine. After molding, the manganese ring's surface carries residual positive electrode dust, which is inserted into the steel casing along with the manganese ring and remains within the positive electrode. During the filling of the negative electrode material into the positive electrode, this residual positive electrode dust can contaminate the negative electrode material, causing micro-short circuits and affecting the battery's normal operating voltage. Therefore, effectively removing residual positive electrode dust to avoid its adverse effects on battery performance has become a pressing technical challenge in the battery manufacturing industry. Existing cleaning methods are inefficient and struggle to completely remove the dust, which not only affects battery quality and safety but also increases production costs and time.

[0017] To solve the above technical problems, such as Figure 1-4 As shown, this utility model designs a powder-removing device for cleaning residual floating dust from a battery positive electrode 3. It includes a base 1, a torsion guide assembly, and a fixing frame 2. The base 1 is fixed to the equipment frame. Several fixing frames 2 are spaced apart along the length of the base 1. The torsion guide assembly is connected to the fixing frame 2 and docked with a transmission mechanism. The torsion guide assembly is used to first torsion the horizontally introduced positive electrode 3 to a vertical state so that its opening faces downwards, and then torsion it back to a horizontal state for exiting. Specifically, the torsion guide assembly includes two first steel wires 4, two second steel wires 5, two third steel wires 6, and one fourth steel wire 7 that are twisted and bent. At the inlet and outlet ends of the torsion guide assembly, the two first steel wires 4 are located on the left side and are attached to the protrusion of the positive electrode 3. The two second steel wires 5 are attached to the top of the positive electrode 3, and the two third steel wires 6 are attached to the bottom of the positive electrode 3. The fourth steel wire 7... The first steel wire 4 is attached to the right opening of the positive electrode 3. In the middle of the twisting guide assembly, the two first steel wires 4 are twisted upwards, the second steel wire 5 is twisted to the right, the third steel wire 6 is twisted to the left, and the fourth steel wire 7 is twisted downwards. Multiple steel wires are precisely attached to different parts of the positive electrode 3, ensuring the stability and guiding effect of the positive electrode 3 during the twisting process. This allows the positive electrode 3 to be accurately positioned during the introduction and export process, improving the positioning accuracy of the positive electrode 3 and the controllability of the cleaning process. Utilizing the principle of gravity falling, the residual floating dust is allowed to fall freely when the positive electrode 3 is transmitted to the middle section of the steel wires through a pushing and shaking method, thereby achieving rapid separation and helping to remove floating dust more thoroughly, optimizing the cleaning effect. By effectively removing floating dust inside the positive electrode 3, this device reduces the risk of contamination of the negative electrode material in subsequent processes, thereby avoiding the problem of micro-short circuits in the battery cell and improving the safety and reliability of the battery.

[0018] In this embodiment, it is further preferred that the fixing frame 2 has a rectangular structure and a rectangular hole on its inner side. The first steel wire 4, the second steel wire 5, the third steel wire 6, and the fourth steel wire 7 pass through the rectangular hole on the inner side of the fixing frame 2 and are fixedly connected to the fixing frame 2 by welding. The rectangular structure design of the fixing frame 2 provides a sturdy frame, making the structure of the entire powder pouring device more stable, while ensuring the precise positioning and fixing of the steel wires. This precise positioning is crucial for ensuring the correct guidance and cleaning effect of the positive electrode 3 when passing through the torsion guide assembly.

[0019] In this embodiment, it is further preferred to include a valve seat 8, which is installed at the end of the base plate. The outer side of the valve seat 8 is provided with bolt holes for installing baffles, and the inner side of the valve seat 8 is provided with through holes for the torsion guide assembly to pass through. This can control the transmission and output process of the positive electrode 3, ensure that the positive electrode 3 is closely arranged, and achieve orderly transmission.

[0020] In this embodiment, it is further preferred that the fixing frame 2 has bolt holes on one side, and the fixing frame 2 is connected to the base 1 by bolts. This makes the installation and adjustment of the fixing frame 2 very convenient. The position or angle of the fixing frame 2 can be quickly adjusted according to actual needs, providing a robust connection method that helps improve the stability and durability of the entire powder pouring device. The bolt connection design also makes it easier to expand or upgrade the powder pouring device in the future. New components can be quickly replaced or added according to technological advancements or production needs.

[0021] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
