An equidistant roll printing machine

Abstract

The invention provides an equally-spaced roller type printing machine. The printing machine comprises a driving pull roller, a driven pull roller, a printing device, a rack, a drying device and a controller; the driving pull roller is driven to rotate by a first driving mechanism, and a metering device is arranged on the driving pull roller; the printing device and the drying device are sequentially arranged in the transmission direction of printing paper; the rack comprises stand columns which are arranged in a symmetrical mode, a crossbeam is arranged on the stand columns, the printing device comprises an ink jetting device, a printing roller and an imprinting roller, the two ends of the printing roller are slidably connected to the stand columns, a first air cylinder is arranged at each end of the crossbeam, the first air cylinders drive the printing roller to slide vertically along the stand columns, the printing roller is driven to rotate by a second driving mechanism, the ink jetting device is located over the printing roller, the two ends of the imprinting roller are rotably installed on the stand columns, the imprinting roller is driven to rotate by a third driving mechanism, the imprinting roller is located below the printing roller, and the imprinting roller and the printing roller are arranged in a parallel mode; the controller is connected with the first driving mechanism, the metering device, the second driving mechanism, the third driving mechanism and the first air cylinders.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to an equidistant roller printing machine. Background technique [0002] The general roller printing machine adopts the working method of continuous printing, and the printing roller is provided with printed text. When printing at equal intervals on the printing paper, if the printing roller's head-to-tail gap along its circumference is just equal to the interval When printing the required printing distance, the general roller printing machine can realize it. If the printing distance on the printing roller along its circumference is just not equal to the printing distance required for interval printing, the general roller printing machine cannot realize the printing distance. Print on paper with equal spacing as required. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an equidista...
