Embodiment

[0023] The new automatic flat film scraping machine of this example includes: a base (1), a scraping table (2), a flat scraper (3), a flat scraper adjustment device, a scraper unit, and a drive unit.

[0024] A new type of flat film scraping machine, the bottom of which is a cuboid base (1) for supporting the whole scraping machine, the level of the base (1) is adjusted by adjusting the base lifting rod (15). The film scraping table (2) is located above the base (1). The film scraping table (2) and the film scraping plate (3) are connected by four double-helix screws (4), and the film scraping is adjusted by rotating the double-helix screws (4). The height and level of the slab (3). The scraper (6) is suspended below the scraper bracket crossbeam (11) by two springs (9), and the two spiral micrometers (7) on the crossbeam (11) are against the top of the scraper (6), and the spiral micrometer (7) Used to adjust the height and level of the scraper. After the position of the sc...

Abstract

The invention discloses a novel automatic flat-plate film-coating machine, which includes a pedestal, a film-coating bench, a film-coating plate, a film-coating plate adjustment device, a scraper unit and a driving unit. The scraper unit includes: a scraper, a scraper adjustment device and a scraper support, wherein the driving unit is connected to the scraper unit for controlling the operation of the scraper. The film-coating plate adjustment device is used for adjust the height and the level of the film-coating plate. The scraper adjustment device is used for adjust the height and the level of the scraper. The thickness and uniformity of a film are accurately controlled by means of cooperative effects of the film-coating plate adjustment device and the scraper adjustment device. By means of a rotary lifting device, the scraper rotates around a shaft, so that the scraper is convenient to clean after film coating. The novel automatic flat-plate film-coating machine can not only coat glass with a film but also coat a film on the base materials such as nonwoven cloths according to requirement. The machine is uniform in film thickness, is good in repeatability, is simple in processes and is convenient to use.

Description

technical field [0001] The invention specifically refers to an automatic flat film scraping machine. Background technique [0002] The traditional film casting method is to use a flat plate to manually scrape the film, that is, pour the casting liquid on the flat plate, manually scrape the film with a scraper, and control the film thickness through the wire on the scraper. Obviously, it is difficult to control the strength of the hand and the speed of scraping the film when scraping the film, resulting in uneven thickness of the film, which affects the regularity and reproducibility of the film making, resulting in errors in the experimental data. For this reason, people have designed some film scraping machines that can automatically scrape the film. However, the existing flat film scraping machines only control the thickness of the film by adjusting the height of the scraper. It cannot be kept constant continuously, and the film thickness cannot be precisely controlled; i...
