Embodiment Construction

[0008] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0009] The structure of the drying device of the multi-color gravure printing machine oven of the present invention, as shown in the figure, the length of the oven is set to 10 meters, the temperature of the oven is positioned at 70 degrees, the printing roller material enters from one end of the oven, and passes through in 4 seconds. Oven, because the rotation of the roller shaft and bearing drives the screen, and the printing material also rotates at the same time, so that the printing material passes through the oven smoothly, so that the printing speed can reach 150 meters per minute.

[0010] The technology of the invention makes the printing color registration of the multi-color gravure printing machine stable, further increases the printing speed, improves the work efficiency, and obtains good printing effect.

Abstract

The invention discloses a drying device of a multicolor intaglio press oven, wherein infrared drying and electric heating drying modes or microwave drying mode can be adopted in the oven. The oven is internally provided with a plurality of guide rollers or the guide rollers are arranged to drive a screen to roll along with a web material, and each guide roller is internally provided with a rolling shaft and a bearing. The invention can ensure that tension for printing the web material is stably treated and the material is uniformly stretched under constant tension, thereby achieving uniform drying and avoiding the phenomenon that the materials are not dried during lower surface plating. Compared with the prior art, the invention can ensure that printing casing of the multicolor intaglio press is stable, thereby further improving printing speed and working efficiency and achieving favorable printing effect.

Description

1. Technical field [0001] The invention relates to a drying device for an oven of a multicolor gravure printing machine, in particular to a drying device for an oven for an ink multicolor gravure printing machine. 2. Background technology [0002] At present, my country's printing and packaging industry, like foreign countries, is developing in the direction of environmentally friendly packaging, and the awareness of environmental protection is increasing. Environmentally friendly pure water ink is the goal of the development of the printing and packaging industry around the world. Most of the printing industry now uses traditional solvent ink, which is a volatile and dry ink. The volatile gas pollutes the environment, is flammable and explosive, and damages the health of workers. The solvent in pure water ink is water, which is a solvent that does not emit, with slow drying speed and low work efficiency, resulting in poor printing registration stability, low printing regist...
