PVC tablecloth printing process

Abstract

The invention discloses a PVC tablecloth printing process, and belongs to the technical field of PVC printing processes. The process is characterized in that a printing plate roller is manufactured according to a pattern, the printing plate roller is used for intaglio printing, and the engraving depth of the printing plate roller is 15 microns; printing material is arranged and fed on a machine; after the machine is started up, (1) the printing material is preheated; (2) the printing material is aligned with a color printing plate roller; (3) after coloring of a first color is completed, the printing material is dragged to be subjected to drying and color fixing at first through a drying box, wherein, the wind power and temperature of the drying box are increased, a drying heat source of the drying box is improved to be a UV lamp, the air volume is 18-20 m <3> / s, and the temperature reaches 35-45 DEG C after blowing is carried out by wind power; (4) then, printing color moments are lengthened, the blowing distance of natural wind is increased to 330-400 cm, and then residual water vapor is thoroughly blown away, and all the color moments pass through the process; and if the patternhas three colors, three times of process is carried out, if the pattern has four colors, four times of process is carried out, and so on; after printing of the last color sequence is completed, winding is carried out by a material winding frame to obtain a large-roll semi-finished product; and the large-roll semi-finished product is divided into small-roll finished products required by the market by a roll dividing machine.

Description

technical field [0001] The invention relates to a printing process of PVC tablecloth, which belongs to the technical field of PVC printing process. Background technique [0002] Water-based ink printing PVC (including colored PVC, transparent PVC and its composites) tablecloths and placemats, the printing process includes direct printing and transfer printing, but the above printing process cannot quickly dry after printing PVC materials with water-based ink, and the coloring is not good The shortcomings of the water-based ink printing process are: oven temperature 35-45°C, and 23-30°C after blowing; The depth of the line on the printing plate roller is 30-50μm; the wind force is 15m 3 / s; the oven uses ordinary heat pipes; the length of the drying path is 220-250cm. The above-mentioned problems are long-standing technical problems in this field. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior...
