Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and in particular relates to a negative electrode scraping device for nickel-hydrogen battery production. Background Art

[0002] In the production and processing of the negative electrode of the nickel-hydrogen battery, the wet slurry pulling process is generally adopted. The core material is immersed in the electrode mixture slurry, so that the electrode mixture slurry is coated on both sides thereof, and then the coating amount of the electrode mixture slurry is adjusted. The coating amount of the electrode and agent slurry is adjusted to the required range, that is, the core material coated with the electrode mixture slurry is passed through the gap between a pair of scraping fixtures to scrape off excess electrode mixture slurry.

[0003] After searching, the patent with application number 201620012233.8 discloses a nickel-metal hydride battery negative electrode scraping device. This patent effectively improves the ruler adjustment accuracy by setting a laser thickness gauge and a movable knife that can automatically adjust the gap. Automatic adjustment replaces manual adjustment, improves the adjustment efficiency, ensures the consistency of the electrode piece, and improves the quality rate of the final product. However, it uses a flat-mouthed fixed knife and a movable knife. During the scraping process of the electrode piece, due to the certain viscosity of the slurry, it will accumulate at the bottom of the fixed knife and the movable knife, and it is not easy to fall into the slurry tank, thus affecting the scraping effect.
