Abstract
The invention belongs to the technical field of application of coating plate rollers, and particularly relates to a scraper device for protecting a coating plate roller. The scraper device comprises a scraper holder, wherein a scraper is arranged on a scraper holder close to one end of the coating plate roller; a baffle plate is arranged below the scraper; the baffle plate comprises an upper section, a middle section and a lower section; the upper section is a vertical plate; the middle section is an inclined plate; the lower section is an arc-shaped plate. According to the invention, the baffle plate is arranged below the scraper, and in the high-speed running process of the coating plate roller, ink scraped down flows towards the baffle plate at a relatively high linear speed and is then reflected to a contact area of the scraper and the coating plate roller, and solid particles between the scraper and the coating plate roller shed off under the flushing action of the quickly-reflected ink, so that the coating plate roller is prevented from being scratched by the solid particles, and coated defective products are greatly reduced.
Description
technical field
The invention belongs to coating roller applied technical field, be 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.
summary of the invention
The object of the present invention is to provide a kind of doctor blade device protecting coating roller.
For achieving the above object, the present invention 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 present invention 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 invention;
Fig. 2 is structural representation of the present invention.
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 present invention 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.
