Silk-screen printing system and printing method thereof

Abstract

The invention discloses a silk-screen printing system. The silk-screen printing system comprises a paper supply part, a main body part and a paper collection part, wherein the paper supply part, the main body part and the paper collection part are sequentially arranged from an initial station to an ending station. The main body part comprises a paper delivery cylinder, a paper conveying cylinder,an impression cylinder and a paper collection cylinder. The input end of the paper delivery cylinder is connected with the output end of the paper supply part, and the output end of the paper deliverycylinder is connected with the input end of the paper conveying cylinder. The output end of the paper conveying cylinder is connected with the input end of the impression cylinder, and the output endof the impression cylinder is connected with the input end of the paper collection cylinder. The output end of the paper collection cylinder is connected with the input end of the paper collection part. The paper conveying cylinder comprises a double-diameter paper conveying cylinder and a small-diameter paper conveying cylinder. The paper delivery cylinder and the small-diameter paper conveyingcylinder are arranged at the right side and the left side of the double-diameter paper conveying cylinder correspondingly. The impression cylinder is arranged above the small-diameter paper conveyingcylinder. The paper collection cylinder is arranged at the left side of the impression cylinder. Based on the technical characteristic that a plane printing substrate is rolled into a barrel-shaped printing substrate in the printing process, the requirement of the special printing effect is met; printing materials are supplied continuously; and the materials are connected closely, and the flatnessis good.

Description

technical field [0001] The present invention relates to a rotary screen printing device, in particular, to a screen printing system and a printing method thereof. Background technique [0002] The existing printing production technology mainly includes flat screen printing method and rotary screen printing method. The traditional flat screen printing method has low printing speed, slow ink curing speed, difficult to control printing quality, and large consumption of printing materials, which cannot meet the needs of large-scale and batch production. Rotary screen printing adopts a cylindrical screen printing plate, a fixed ink scraper is installed in the cylinder, and the cylindrical printing plate and the substrate move synchronously at the same linear speed. Screen printing is a direct printing method, suitable for small batch production, packaging products with high printing appearance requirements, unlimited cardboard thickness, and no damage to strength. The main diff...
