Problems solved by technology
[0002] At present, the traditional printing machine squeegee device adopts a fixed-position structure, and the squeegee device can only do overall reciprocating motion, and cannot move in translation
Since the scraper device is reciprocating as a whole, the whole scraper device has heavy mass and large inertia, so the required driving electric power is large and the vibration generated by the movement is large; at the same time, because the scraper cannot move in parallel, in order to ensure a suitable scraper angle, the printing plate The diameter cannot change greatly, so the difference between the maximum plate diameter and the minimum plate diameter will not exceed 200mm

The invention discloses a movable scraper device which comprises an upper scraper part, a lower scraper part and a fixing part, and further comprises a reciprocating motion mechanism, a front-back motion mechanism, a lifting mechanism and a rotating mechanism, wherein the reciprocating motion mechanism performs reciprocating motion towards the upper scraper part; the front-back motion mechanism moves front and back towards an entire scraper; the lifting mechanism moves up and down along a scraper box towards the upper scraper part; and the rotating mechanism rotates towards the upper scraper part. When the movable scraper device performs reciprocating motion, only the upper scraper part performs reciprocating motion, thereby effectively reducing driving power required for the motion and reducing vibration generated by the motion; meanwhile, the scraper can be adjusted by a plurality of degrees of freedom (front-back moving of the entire scraper; up-down moving of the upper scraper part along the scraper box; and rotating of the upper scraper part); and accordingly, the scraper can not only perform translation but also rotate to keep a proper scraper angle, so that the adaption to a big radius change can be achieved.
Description
Technical field [0001] The utility model is mainly used for printing presses with super-large diameter printing plates and printing plates whose diameters vary greatly. Background technique [0002] At present, the traditional printing machine squeegee device adopts a fixed-position structure, and the squeegee device can only perform an overall reciprocating movement, and cannot move in translation. Since the scraper device is reciprocating as a whole, the entire scraper device has heavy mass and large inertia, so the required driving electric power is large, and the vibration generated by the movement is large; at the same time, because the scraper cannot move in parallel, in order to ensure a suitable scraper angle, the printing plate The diameter cannot be changed greatly, so the difference between the maximum and minimum plate diameters will not exceed 200mm. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the utility model provides a...
