Paste baffle used for polar plate paste coating and arranged on storage battery paste coating machine

The utility model discloses a paste baffle used for polar plate paste coating and arranged on a storage battery paste coating machine. The paste baffle comprises a board, wherein the board is provided with at least one arc-shaped groove matched with a press roll of the paste coating machine; a strip-type paste outlet is formed in the arc-shaped groove; a side wall where one of the long side of the paste outlet is a paste guiding wall; the paste guiding wall comprises a paste guiding surface butted with the paste outlet; and the paste guiding surface is raised in the middle and gradually descends towards two ends along the length direction of the paste outlet. The paste baffle has the advantages that the paste guiding surface is raised in the middle and gradually descends towards two ends along the length direction of the paste outlet, so that paste is conveniently discharged at two sides of the paste outlet, the paste discharging quantity at two sides of the paste outlet is increased, the lead paste distribution can be uniformly controlled and the flatness of a polar plate is guaranteed; according to the current storage battery process design, the lead paste use ratio of the upper part of the polar plate is higher than that of the lower part of the polar plate, the active substance use ratio can be increased through balancing the active substance distribution and the battery performance is increased; the arc-shaped paste guiding groove is arranged, so that the problems that gap is left when paste is discharged at two sides of the paste outlet and the polar plate cannot be fully coated can be prevented.
