Abstract

The invention discloses a screen frame lifting device for a printing machine. The screen frame lifting device for the printing machine comprises a machine frame, a lifting transmission device and a screen frame, wherein the lifting transmission device is installed on the machine frame, and the screen frame is installed on the lifting transmission device. The screen frame can be widely applied to large-area self-aligning printing machines, the space of the whole device is greatly reduced, and meanwhile the demands for precision and rigidity of the screen frame in the process of lifting are met.

Description

technical field [0001] The invention relates to the technical field of printing machines, and more specifically relates to a screen frame lifting device for printing machines that occupies less space and has high motion precision. Background technique [0002] With the development of the packaging substrate and flat panel display industry, the size of the printed items needs to increase continuously, and the corresponding screen frame size also increases accordingly; take the printed item size of 600mm×600mm as an example: the screen frame size needs to be at least 1100mm×1100mm. The minimum size of the lifting device for fixing the screen frame needs to be 1500mm×1500mm; the traditional small-area printing machine places the screen frame lifting mechanism on the platen of the equipment, and uses a motor to drive the screen frame up and down synchronously; Due to the large footprint and low motion accuracy, it cannot be realized by traditional methods. Therefore, need to de...
