Sliding support device for printing structure of printing machine
Technical Field
The invention relates to a supporting device of a printing machine, in particular to a sliding supporting device for a printing structure of the printing machine, and belongs to the technical field of printing.
Background
A printer is a machine that prints text and images. Modern printing presses typically consist of mechanisms for plating, inking, stamping, feeding (including folding), etc. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is applied to the position on the printing plate where the characters and images are placed by hand or printing machine, then it is directly or indirectly transferred to other printing material.
When large-scale printing stocks (such as huge posters) with small quantity are printed, a guide rail type printing machine is needed to be used, a guide rail type printing assembly slides back and forth on the huge printing stocks to print and dye, the existing guide rail type printing guide rail has a simple supporting structure, is easy to deflect, has an imperfect rolling structure for the printing stocks, and is easy to cause the situations of repeated printing or blank printing due to the deflection and the fold of the printing stocks.
