Problems solved by technology
At present, the cigarette factory cigarette labels printed by the company are all gravure printing products. The original gravure printing machine squeegee locking adjustment device (see figure 1 ), in the process of use, it is found that the handwheel of the locker cannot be locked tightly and the handwheel of the locker cannot be loosened after locking. Company production efficiency and product qualification rate
Through long-term careful observation by the inventor, it is found that the main reason is that the locking device A and locking device B are not synchronized during the operation, which causes the scraper to tilt, resulting in a gap between the front end of the locking screw and the connecting groove of the locking device connection block. The force on the side makes the lock screw and the screw teeth of the lock screw mounting seat fit incorrectly, resulting in the adjustment screw not being able to rotate, and it can only be rotated by force; if the synchronization difference between lock A and lock B is too large, It will also cause the distance between the two locking screws and the distance between the two locking screw mounting seats to be unequal, causing the locking screw to not rotate, and it is difficult to achieve the locking device A and locking when operating the locking adjustment device. Device B is fully synchronized

Embodiment 1
[0019] Such as figure 1 As shown, in the original gravure printing machine scraper locking adjustment device, since the two scraper connecting seats are respectively fixed on the locking device connecting block by two bolts, the two locking screw mounting seats 5 are also respectively It is fixed on the bottom plate 9 of the doctor blade by two bolts, so when the locker is used to adjust the parallelism between the doctor blade and the printing plate roller, if the locker A and the locker B are out of sync, the doctor blade 10 Tilting will make the front end of the locking screw 4 and the side of the connecting groove of the locking device connecting block be stressed, and the fit between the locking screw 4 and the locking screw mounting seat 5 will not be correct, resulting in the locking screw 4 not turning. , can only be forced to rotate through afterburner. There is another situation: if the locker A and the locker B have too much difference in synchronization, it will a...

The invention discloses an improved type doctor blade locking and adjusting device for an intaglio printing press. The improved type doctor blade locking and adjusting device for the intaglio printing press comprises doctor blade connecting bases, locking threaded rods, locking threaded rod mounting bases, locking device hand wheels, doctor blade base plates and a doctor blade. The locking device hand wheels are arranged at the rear ends of the locking threaded rods, and the doctor blade is connected to the two doctor blade connecting bases. The improved type doctor blade locking and adjusting device for the intaglio printing press is characterized by further comprising movable connecting blocks, movable connecting block fixing shafts, adjustable locking threaded rod mounting bases and spacer bushes. The movable connecting blocks are arranged in the front ends of the locking threaded rods in a penetrating mode, the doctor blade connecting bases are connected to the movable connecting blocks through the movable connecting block fixing shafts, the adjustable locking threaded rod mounting bases are fixedly arranged on the doctor blade base plates through the spacer bushes, and the locking threaded rods are arranged in the adjustable locking threaded rod mounting bases in a penetrating mode through locking threaded rod mounting thread tooth holes. According to the improved type doctor blade locking and adjusting device for the intaglio printing press, when operators change and adjust the doctor blade, convenience and fastness are achieved, and time and labor are saved.
Description
technical field [0001] The invention relates to a gravure printing machine, in particular to a doctor blade locking adjustment device of the gravure printing machine. Background technique [0002] Gravure printing machine is the most important printing equipment in cigarette label printing enterprises. Gravure printing machine is the abbreviation of gravure printing machine. Gravure printing refers to the printing method in which text and images are lower than the surface of the printing plate. The working principle of the gravure printing machine is that the printing plate roller is soaked in the ink tank. After the plate roller rotates up, the scraper scrapes off the excess ink on the surface of the printing plate, and then presses the paper on the printing plate roller through the embossing roller to make the gravure The ink on the incoming graphic is transferred to the paper, thus completing the printing. At present, the cigarette factory cigarette labels printed ...
