Screen head device of rotary screen printing machine

Abstract

The utility model discloses a screen head device of a circular screen printer, which comprises a circular screen seat, a middle sleeve and a chuck which are sequentially and coaxially sleeved from inside to outside, the circular screen seat is hinged with the middle sleeve through a first pin shaft assembly, and the middle sleeve is hinged with the chuck through a second pin shaft assembly. The axis of the first pin shaft assembly, the axis of the second pin shaft assembly and the axis of the rotary screen seat are perpendicular to one another in a pairwise mode. According to the screen head device of the rotary screen printing machine, the stress of the chuck in any direction can be decomposed into the force in the two directions of the axis of the first pin shaft assembly and the axis of the second pin shaft assembly; the chuck can swing along the axis of the first pin shaft assembly and swing along the axis of the second pin shaft assembly, in other words, the chuck can swing in any direction and change the direction to convert stress so as to adapt to installation and operation of the rotary screen, and the probability of screen twisting and screen breaking is greatly reduced.
