Printing equipment

Abstract

The invention relates to the field of printing devices, and discloses printing equipment. The printing equipment comprises a machine frame and a fixing frame, wherein a through groove which penetratesthrough the fixing frame is formed in the fixing frame, and a through hole is formed in the side wall of the fixing frame; cross shafts are fixedly connected to the two ends of the fixing frame, thecross shafts are coaxially and fixedly connected with gears, and a crankshaft is arranged below the fixing frame; a main journal of the crankshaft is rotationally connected with a first connecting rod, the other end of the first connecting rod is rotationally connected with a printing tube, the printing tube is slidably connected to the machine frame, and the top of the printing tube is connectedwith a printing plate; the printing tube is further connected with a cutting knife, push rods are rotationally arranged on the portions, on the two sides of the printing tube, of the main journal correspondingly, the other ends of the push rods are rotationally connected with racks, the racks are slidably connected to the machine frame, and the racks can be meshed with the gears, and second connecting rods are rotationally connected to the portions, at the two ends of the printing tube, of the main journal; the other ends of the second connecting rods are rotationally connected with screw rods, the screw rods are in threaded connection with nuts, and the top ends of the nuts are hinged to rotating blades. According to the device, automatically turning over a paper board during printing isrealized.

Description

technical field [0001] The invention relates to the field of printing devices, in particular to a printing device. Background technique [0002] Printing (Printing, Graphic Art) is to transfer the ink to the surface of paper, fabrics, plastics, leather and other materials through the process of plate making, ink application, and pressure to copy the original content in batches. Technology. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. According to the relative positions of graphic and non-graphical areas on the printing plate, common printing methods can be divided into four categories: letterpress printing, gravure printing, lithographic printing and stencil printing. [0003] Traditional printing devices usually print on one side, which cannot meet the needs of double-sided printing for some cardboards. Therefore, in order to meet the needs, double-sided printing devices are currently wide...

AI Technical Summary

Problems solved by technology

[0004] The present invention intends to provide a printing equipment to solve the problem that traditional double-sided printing equipment requires two printing rollers to drive the cardboard forward, which may easily cause paper jams and inconsistent rotation of the two printing rollers, which will affect the printing quality.
