Joint elbow type lifting device of screen plate frame fixing rack

Abstract

The invention discloses a joint elbow type lifting device of a screen plate frame fixing rack. The device comprises the screen plate frame fixing rack, a front lifting mechanism and a rear lifting mechanism, wherein the rear lifting mechanism is connected with a traction pillar; the traction pillar is pivoted with the rear end of the screen plate frame fixing rack; and the front end of the screen plate frame fixing rack is placed on a rack. The rear end of the screen plate frame fixing rack and the traction pillar adopt a joint elbow type pivoting manner, and the front end of the screen plate frame fixing rack is placed on the rack and not fixed, so that the front end and the rear end of the screen plate frame fixing rack can be lifted synchronously or asynchronously, tilt stripping action can be performed, the screen plate frame fixing rack is suitable for printing workpieces with higher accuracy requirements, and the problems that a screen plate frame fixing rack of an ordinary printing device shakes during lifting motion and workpieces shift are solved. The joint elbow type lifting device of the screen plate frame fixing rack reasonably utilizes the space of the device, and is simple and compact in structure, and easy to implement.

Description

technical field [0001] The invention belongs to the field of printing equipment, and in particular relates to a lifting device for a screen frame fixing frame of printing equipment. Background technique [0002] At present, the screen frame fixing frame used in the printing equipment industry adopts the vertical lifting device of the reducer, and the impact and vibration cannot be effectively eliminated. When vertically lifting, it is easy to be caused by the large-area contact of the screen or the adhesion of printing chemicals. The workpiece to be printed is driven by the huge airflow, that is to say, the existing printing screen frame fixing frame lifting device is prone to vibration and workpiece displacement during the lifting movement, and is not suitable for high-speed reciprocating printing of relatively thin workpieces. Moreover, in the existing screen frame fixing frame lifting device, it is common to be unable to realize effective buffering, the design takes up a ...

[0002] At present, the screen frame fixing frame used in the printing equipment industry adopts the vertical lifting device of the reducer, and the impact and vibration cannot be effectively eliminated. When vertically lifting, it is easy to be caused by the large-area contact of the screen or the adhesion of printing chemicals. Huge airflow drives the workpiece to be printed, that is to say, the existing printing screen frame fixing frame lifting device is prone to vibration and workpiece displacement during lifting movement, and is not suitable for high-speed reciprocating printing of relatively thin workpieces

Moreover, in the existing lifting device of the screen frame fixing frame, it is common that effective buffering cannot be realized, the design takes up a large space, and there is no inclined stripping work piece, etc.
