Specifically, a strip-shaped hole 212 may be formed in the ink blocking plate 211, and a bolt may be inserted through the strip-shaped hole 212 to mount the ink blocking plate 211 to the doctor blade 210. More specifically, the two ends of the ink blocking plate 211 may be bent at a certain angle, and a plurality of screw holes matched with the bolts are formed on the bent surface, so that the ink blocking plate 211 is mounted on the bent surface of the doctor blade 210 through at least two bolts; at least two bolts can be arranged on the doctor blade 210, and the ink baffle 211 is arranged on the doctor blade 210 through the matching of nuts and bolts; two mounting plates may be welded to both ends of the ink blocking plate 211, and the ink blocking plate 211 may be mounted on the mounting plates by the cooperation of bolts and nuts. In addition, a slider engaged with the strip hole 212 may be provided on the doctor blade 210, and a latch may be provided to fix the ink blocking plate 211 after the adjustment. It should be noted that the connection manner of the ink blocking plate 211 and the doctor blade 210 is not limited to the above-mentioned embodiments, and only allows the position of the ink blocking plate 211 relative to the doctor blade 210 to be adjusted and locks the ink blocking plate 211 after the adjustment.
Furthermore, the doctor blade 210 is marked with scale marks along the length direction of the strip-shaped hole 212, when the position of the ink blocking plate 211 relative to the doctor blade 210 is adjusted, the scale marks can be used as a standard, and the ink blocking plates 211 at two ends of the same doctor blade 210 can be ensured to be positioned on the same horizontal plane after adjustment, so that the situation that the amount of slurry at two ends of the doctor blade 210 passing through a printing plate is different during printing is prevented, and the printing quality is influenced.
As a further optimization of the present embodiment, the screen printing apparatus of the present embodiment further includes 2 balancing mechanisms 400, and the balancing mechanisms 400 and the doctor blade 210 may be fixedly connected by welding, riveting, or the like, or detachably connected by screwing. The balancing mechanism 400 is provided to provide an upward force to the doctor blade 210 when the doctor blade 210 descends, so that the descending speed of the doctor blade 210 is continuously slowed down, and the doctor blade 210 is prevented from scraping printing plates. To achieve this, a balance cylinder 410 may be provided on the mounting block 100, and a movable end of the balance cylinder 410 is connected to the doctor blade 210. After the doctor blade 210 descends for a certain distance, the balancing cylinder 410 starts to work and provides upward force to the doctor blade 210, the speed of the lower carriage of the doctor blade 210 is continuously reduced to the extent that the printing plate is not scratched under the resistance provided by the balancing cylinder 410, and the edge of the doctor blade 210 finally contacts the printing plate at a slower speed and finally stops on the printing plate. The balancing cylinder 410 may be a hydraulic cylinder as long as it can provide resistance to the doctor blade 210.
As another embodiment, in the present embodiment, the 2 ink recovery blades 220 are located between the 2 scraping blades 210.
