A plastic woven fabric printing machine

Abstract

The invention discloses a plastic woven fabric printing machine. The plastic woven fabric printing machine comprises an emptying device, a flexible printing device and a winding device, wherein the emptying device comprises an emptying machine base, a supporting column, a bearing seat, a balance beam, a U-shaped positioning block, a first rotating wheel, a second rotating wheel, a stand column, a guide wheel seat, a first guide wheel and a first pressure wheel; the flexible printing device comprises a printing stander, an intermediate deviation correction mechanism, a main traction device, a front side printing device and a back side printing device; the back side printing device and the front side printing device have an identical constitution and an identical structure and are installed on the left side of the main traction device in a mirroring manner; and the winding device is arranged behind the flexible printing device. Hot air for drying and a cooling fan for lowering the temperature are also arranged behind the front side printing machine and the back side printing machine, and then a two-sectional drying way of the hot air drying is adopted, so that the drying effect is guaranteed, the input of excessive heat is avoided when in drying, the elongation variation of a printing material is stabilized, and the color register is more accurate.

Description

technical field [0001] The invention relates to a plastic woven cloth printing machine. Background technique [0002] At present, roll-to-roll printing generally adopts flexographic printing technology, and the principle is the same, including pre-press feeding unit, printing unit and winding unit, and also has a tension control unit, but in printing such as double-layer plastic woven cloth When using high-quality printing materials, the tension is difficult to control, which makes it difficult to control the printing color registration accuracy. This is more obvious when the printing speed is faster and the printing length is longer. Moreover, the printed materials after printing must be dried by a drying device. Due to the thick thickness of the double-layer plastic woven cloth, the heat absorption is large, the drying time is short and the effect cannot be achieved, and the plastic woven cloth softens after a long time, which affects the printing quality of the reverse si...

[0002] At present, roll-to-roll printing generally adopts flexographic printing technology, and the principle is the same, including pre-press feeding unit, printing unit and winding unit, and also has a tension control unit, but in printing such as double-layer plastic woven cloth When using high-quality printing materials, the tension is difficult to control, which makes it difficult to control the printing color registration accuracy. This is more obvious when the printing speed is faster and the printing length is longer. Moreover, the printed materials after printing must be dried by a drying device. Due to the thick thickness of the double-layer plastic woven cloth, the heat absorption is large, the drying time is short and the effect cannot be achieved, and the plastic woven cloth softens after a long time, which affects the printing quality of the reverse side and restricts the use of flexographic printing technology on this type of printing materials.
