Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it is understood that "first" and "second" are only used for convenience of expression and should not be understood as limitations to the embodiments of the present invention, and the following embodiments do not describe any more.
In an embodiment provided by the present invention, referring to fig. 1, a doctor blade device includes: a first doctor blade 1, a frame 2 and at least one second doctor blade 3;
one end of a first ink scraping knife 1 is connected with a frame 2, and in the first ink scraping process, the other end of the first ink scraping knife 1 is used for acting with a screen printing plate 4 bearing ink;
one end of the second doctor blade 3 is connected with the frame 2, and in the second doctor process, the other end of the second doctor blade 3 is used for acting with the screen 4 when the first doctor blade 1 does not act with the screen 4.
Specifically, the action means that the doctor blade comes into contact with the screen 4 and presses the ink, thereby completing printing.
The first ink scraping knife 1 is arranged at one point of the rack 2, the second ink scraping knife 3 is arranged at the other point of the rack 2, when ink scraping is carried out for the first time, the first ink scraping knife 1 and the screen printing plate 4 are arranged at a certain angle, and proper pressure is applied to realize ink printing; and after the first ink scraping is finished, the first ink scraping knife 1 is far away from the screen printing plate 4, and the second ink scraping knife 3 is close to the screen printing plate 4, so that the second ink scraping is carried out. Specifically, the first wiping refers to applying pressure to the screen 4 from one side to print ink to the other side, but in the process, the ink is not wiped and printed back and forth; the second wiping is to print the ink from the other side to the original side. Obviously, applying a suitable pressure to achieve a suitable pressure in ink printing means that at this pressure level, the doctor blade is able to achieve printing without damaging the screen 4 due to excessive pressure.
It should be explained that, in the process of performing ink scraping printing, the ink scraping printing is performed between the ink scraping blade and the screen 4 at a certain inclination angle, that is, the ink scraping blade does not act on the screen 4 perpendicularly, after the ink scraping is completed for one time, the ink is concentrated on one side of the ink scraping blade forming an acute angle with the screen 4, and if the ink is to be scraped again, the ink needs to be transferred to the original side by the ink returning blade, and then the ink is scraped by the ink scraping blade. The ink return blade does not have the ink scraping function, and in the process of scraping ink, for the speed of accelerating printing ink printing, the utility model discloses set up first ink scraping blade 1 and at least one second ink scraping blade 3, first ink scraping blade 1 is after scraping ink, through second ink scraping blade 3, has both played the effect of ink return, has also played the speed of scraping ink for the speed of scraping ink printing can improve probably and be the twice before. If only one first doctor blade 1 is arranged, ink still needs to be returned in the ink scraping process, at the moment, the frame 2 needs to be adjusted, the position of the first doctor blade 1 is adjusted to the position of the second doctor blade 3, the adjustment difficulty is increased, the required time is prolonged, and the ink printing speed cannot be increased. Therefore, the utility model provides a doctor blade device has simplified operation process greatly for printing ink printing speed.
In this embodiment, the frame 2 is provided with a first adjusting mechanism and a second adjusting mechanism; the first adjusting mechanism is connected with one end of the first ink scraping knife 1 and is used for adjusting the first ink scraping knife 1 to move along the direction vertical to the screen printing plate 4; the second adjusting mechanism is connected with one end of the second doctor blade 3, and the second adjusting mechanism is used for adjusting the second doctor blade 3 to move along the direction vertical to the screen 4.
Specifically, in the present embodiment, the first adjustment mechanism includes: a groove extending along the direction vertical to the screen 4 and an adjusting screw arranged on the groove; one end of the first doctor blade 1 is connected with the frame 2 through an adjusting screw.
