Abstract
The utility model belongs to coating roller applied technical field, is specifically related to a kind of doctor blade device protecting coating roller.This doctor blade device comprises doctor blade holder, and the doctor blade holder near coating roller one end is provided with scraper, and be provided with deflection plate below scraper, deflection plate comprises upper, middle and lower segment, and epimere is vertical plate, and stage casing is hang plate, and hypomere is arc.The utility model is provided with a deflection plate in the below of scraper; in the process that coating roller runs up; the ink scraped flows to deflection plate with linear velocity quickly; reflex to the region that scraper contacts with coating roller again; solid particle between scraper and coating roller splits away off under the ink that quick reflex is gone back rinses; avoid coated panel roller to be scratched by solid particle, greatly reduce the generation of coating substandard products simultaneously.
Description
technical field
The utility model belongs to coating roller applied technical field, is specifically related to a kind of doctor blade device protecting coating roller.
background technology
In coating is produced; need to use coating roller to be coated with product; in the process of coating, often can run into solid particle in ink be stuck between wing and coating roller to fall; directly cause long normal society appears in coated product; produce substandard products, time serious, also can cause the damage of coating roller.
First the way addressed this is that at present is strengthen the filtration to ink, removes solid particle as much as possible, but cannot remove completely; Secondly during coating, coating blade, along the reciprocal short-distance movement of applicator roll generatrix direction, but still there will be solid particle in using and is stuck between wing and roller, causes the damage of coating substandard products and roller.
utility model content
The purpose of this utility model is to provide a kind of doctor blade device protecting coating roller.
For achieving the above object, the utility model is by the following technical solutions:
Protect a doctor blade device for coating roller, comprise doctor blade holder, the doctor blade holder near coating roller one end is provided with scraper, and be provided with deflection plate below scraper, deflection plate comprises upper, middle and lower segment, and epimere is vertical plate, and stage casing is hang plate, and hypomere is arc.
Hypomere is designed to arc, in order to avoid the scuffing to roller when deflection plate contacts with coating roller; Guiding function is played to the discharge falling ink simultaneously.
The height of vertical plate is 20-30mm, and vertical plate is positioned at doctor blade holder one end near coating roller.
The radius of the arc of deflection plate hypomere is 20-30mm, and the minimum range between arc and coating roller is 3-10mm.
Hang plate tilts to the direction near coating roller, and the angle between hang plate and vertical plate is 135-150 °.
The top of vertical plate has been provided with the level board of fixation.
Doctor blade holder is provided with pressing plate by screw, and scraper is arranged between pressing plate and doctor blade holder, is provided with liner plate between scraper and pressing plate, and the level board at deflection plate top to be fixed between scraper and doctor blade holder thus to be fixed on below scraper by deflection plate.
The utility model is provided with a deflection plate in the below of scraper, so can in coating roller, territory, a class leg-of-mutton ink collecting area is formed between scraper and deflection plate, in the process that coating roller runs up, ink in coating roller scrapes by scraper, the ink scraped flows to deflection plate with linear velocity quickly, the region contacted with coating roller below scraper is reflexed to again under the reflex of deflection plate, solid particle between scraper and coating roller splits away off under the ink that quick reflex is gone back rinses, finally clear up away from the two ends of coating roller and the space between deflection plate arc and coating roller, thus the protective effect played coated panel roller, coated panel roller is avoided to be scratched by solid particle, greatly reduce the generation of coating substandard products simultaneously.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structural representation of the present utility model.
detailed description of the invention
Protect a doctor blade device for coating roller, as shown in Figure 1, 2, comprise doctor blade holder 7, the doctor blade holder 7 near coating roller 1 one end is provided with scraper 2; Doctor blade holder 7 is provided with pressing plate 5 by screw 6, and scraper 2 is arranged between pressing plate 5 and doctor blade holder 7, is provided with liner plate 3 between scraper 2 and pressing plate 5; Deflection plate 4 is provided with below scraper 2, deflection plate 4 comprises upper, middle and lower segment, epimere is vertical plate, stage casing is hang plate, hypomere is arc, the top of vertical plate 4 has been provided with the level board of fixation, and level board to be fixed between scraper 2 and doctor blade holder 7 thus to be fixed on below scraper 2 by deflection plate 4.
The height of vertical plate is 20-30mm, and vertical plate is positioned at doctor blade holder 7 one end near coating roller 1; The radius of the arc of deflection plate 4 is 20-30mm, and the minimum range L between arc and coating roller 1 is 3-10mm; Hang plate tilts to the direction of coating roller 1, and the angle R between vertical plate is 135-150 °; Arc avoids the scuffing to roller when deflection plate 4 contacts with coating roller 1, plays guiding function to the discharge falling ink simultaneously.
When the utility model uses, can in coating roller 1, territory, a class leg-of-mutton ink collecting area is formed between scraper 2 and deflection plate 4, in the process that coating roller 1 runs up, ink in coating roller 1 scrapes by scraper 2, the ink scraped flows to deflection plate 4 with linear velocity quickly, the region contacted with coating roller 1 below scraper 2 is reflexed to again under the reflex of deflection plate 4, solid particle between scraper 2 and coating roller 1 splits away off under the ink that quick reflex is gone back rinses, finally clear up away from the two ends of coating roller 1 and the space between deflection plate 4 arc and coating roller 1.
