Open one-scraper structure

Abstract

The invention discloses an open one-scraper structure. The open one-scraper structure comprises a machine frame, a slide seat, a driving mechanism and a scraper assembly, wherein a micro concave roller is rotatably installed on the machine frame, and a material bowl is arranged below the micro concave roller; the slide seat is transversely and slidably installed on the machine frame, and the moving track of the slide seat is parallel to the center line of the micro concave roller; the driving mechanism is installed on the machine frame and used for driving the slide seat to move; and the scraper assembly is installed on the slide seat. Through the implementation mode, the slide seat is driven to slide on the machine frame through the driving mechanism, accordingly, the scraper assembly isdriven to transversely slide, even though a notch formed at the scraper edge of the scraper assembly, generated scraper lines can be removed through other complete positions of the scraper edge when the scraper assembly slides in the transverse direction, and the coating surface effect is ensured. The open one-scraper structure is simple and ingenious in structure and practical in effect.

Description

technical field [0001] The invention relates to an open single scraper structure. Background technique [0002] The scraper structure of the micro-groove roller on the existing lithium battery coating head mainly adopts the structure of the upper and lower scrapers. The diaphragm coating slurry is a water-based slurry. It is difficult to ensure the parallelism of the upper and lower scrapers. Difficult to adjust. In addition, the upper and lower double scrapers will wear the micro-concave roller greatly, resulting in a short service life of the micro-concave roller; The material cannot be scraped clean to form strip residues), cannot be eliminated, and affects the coating surface effect. The upper and lower scrapers need to be disassembled and cleaned frequently, and the repeat positioning accuracy is poor, which cannot meet the quality requirements of customers. Contents of the invention [0003] In order to solve the above problems, the present invention provides an ope...
