Roll type lifting mechanism for thin film digital printing

Abstract

The invention discloses a roll type lifting mechanism for thin film digital printing. The roll type lifting mechanism comprises a base. A vertical plate is vertically connected to the rear end of theupper portion of the base. A top plate is vertically connected to the upper end of the front side face of the vertical plate. Square sliding rods are connected to the left side and the right side of the front end face of the vertical plate. Sliding grooves arranged in a U shape are in sliding connection to the square sliding rods, and a lifting plate is connected between the two sliding sleeves. The left end and the right end of the bottom of the lifting plate are rotationally connected with first connecting rods pairwise through pin shafts. According to the roll type lifting mechanism, the first connecting rods and second connecting rods are driven by synchronously-operating hydraulic cylinders to be bent and get close, and therefore the lifting plate operates downwards; supporting rods,the lifting plate and a printing plate are integrally formed, and then a printing spray head at the bottom of the printing plate carries out ink jet printing on printing paper on the upper portion ofa workbench; and in the whole process, stress of the printing plate can be uniform through the four hydraulic cylinders and the paired supporting rods, and the printing effect is good.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a roll lifting mechanism for film digital printing. Background technique [0002] Digital printing is a printing technology that has developed rapidly in recent years. It adopts the method of directly transmitting, processing and printing data. That is to say, the imaging data is input once, and the imaging component is directly imaged by the control system. For the commonly used digital printing equipment of on-demand inkjet printing, the imaging component is under the control of the control system. When the surface of the substrate such as paper reaches a predetermined position, the piezoelectric crystal in the nozzle generates a pulse to squeeze out the ink, and directly Spray mist ink droplets on the surface of the substrate such as paper to form an image. A major problem faced by the existing printer technology is that the position adjustment of the digital printing platf...

Problems solved by technology

[0004] Although it can solve the above-mentioned problems in the adjustment of the position of the printing platform, there are still shortcomings. Only the motor drives the screw to rotate. When the force is uneven, the force in the middle is larger and the outer side is smaller, which leads to the tilt of the printing nozzle and the printing effect is not ideal.
