Embodiment Construction
[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0013] see Figure 1-2 , the present invention provides a technical solution: a combined flexographic printing machine, including an operating platform 1, a flexographic printing unit 7 and a gravure printing unit 8; A moving block 3 is installed, and an electric push rod 4 is arranged on the side of the moving block 3; a supporting frame 5 is arranged on the top of the moving block 3, and a drying box 6 is installed on the top of the supporting frame 5; the o...

The invention discloses a flexible printing combination printer. The printer comprises an operation platform, a flexible printing unit and a gravure printing unit; by controlling an electric push rodto drive a moving block to move on a moving track, a drying box moves along with the transformation of the printing mode, and the drying efficiency is ensured to be unchanged; platforms of the flexible printing and the gravure printing unit are modularized, and free switching can be realized according to the printing process requirements; when gravure printing is carried out, a driving cylinder drives a plate roller seat to move forwards on a pushing sliding groove, so that a plate roller shaft is close to the operation platform, and therefore the plate roller shaft is matched with an impressing roller; after gravure printing is finished, the process of retracting the impressing roller originally is changed into that the plate roller seat is integrally retracted, and the paper is not movedalong a gravure printing roller, so that the paper is stable, and overprinting is guaranteed to be stable; and the tension is physically separated after the gravure printing, the tension is controlled by the acceleration and deceleration of a servo motor, a tension detection device is installed before and after the gravure printing, and the dead cycle tension control is achieved.
Description
technical field [0001] The invention relates to the technical field of printing equipment, in particular to a combined flexographic printing machine. Background technique [0002] With the country's prevention of air pollution, the emission of VOCs in the printing industry has become a key control object. In order to reduce environmental pollution, gravure printing in the printing industry is facing a huge survival crisis because of 70% VOCs emissions. At present, the most common method is to treat the emitted VOCs so that they will not be directly discharged into the atmosphere, but the treatment cost is high. Another way is gravure solvent ink, ink ink. Because the VOCs of ink are extremely low, it meets the national requirements for direct emission of environmental protection. However, due to the low quality of printed matter caused by ink-based printing, it is still under research and development, so there is currently no good alternative to gravure printing. Conten...
