Elliptical printing machine and printing method of elliptical printing machine in movement of printing bedplates

Abstract

The invention relates to an elliptical printing machine and a printing method of the elliptical printing machine in movement of printing bedplates. The method comprises the steps as follows: printing stock bedplates and a printing stock bedplate bracket of the elliptical printing machine are in continuous running under the driving of a delivery mechanism; when the printing stock bedplate bracket runs to the preset position of a printing station, printing head brackets and printing head components thereof in the printing station are in synchronized running with the printing stock bedplate bracket, and the printing head components begin to execute the printing action, and after printing is completed, the printing head brackets and the printing head components thereof stop forward-movement and return to the preset position; the printing stock bedplate bracket and the printing stock bedplates continuously keep moving forwards. As the printing stock bedplate bracket and the printing stock bedplates can be in synchronized running with the printing head components, a common motor can be adopted as a conveyer belt power source without using a servo motor, and the cost of the whole equipment is greatly reduced; meanwhile, continuous running can also improve the production efficiency, and the synchronized operation method can eliminate the positioning errors, and further improve the printing precision.

Description

Technical field: [0001] The invention relates to the technical field of printing machines, in particular to an elliptical printing machine and a printing method thereof during the movement of a printing platen. Background technique: [0002] The printing head bracket of the existing elliptical printing machine is fixedly installed on the main platform. When the platen of the substrate is driven by the conveyor belt and runs below the printing head bracket, it stops running immediately, and then the printing head bracket on the printing head The printing head assembly is lowered and pressed against the substrate platen for printing. After printing, the print head assembly is separated from the substrate platen, and the substrate platen bracket is driven away by the transmission mechanism. The prior art mainly has the following deficiencies: this operation method needs to use a servo motor to drive the transmission belt device, which has high cost, and the work efficiency of p...

AI Technical Summary

Problems solved by technology

The prior art mainly has the following deficiencies: this operation method needs to use a servo motor to drive the transmission belt device, which has high cost, and the work efficiency of printing processing in the intermittent start-stop operation method is low; secondly, the printing head support The one-static-one-moving mode of fixed substrate platen movement is more prone to positioning errors with the increase of running time and equipment wear, and with the lengthening of the assembly line, the positioning error will be further enlarged, which will affect the printing accuracy and printing effect. There are printing errors such as ghosting and blurring; moreover, when using servo motor control, many electronic components are used, and the electronic components are easily malfunctioned or malfunctioned by external interference, which will adversely affect the operation of the entire equipment
