Curved surface printing system and method

Abstract

The invention discloses a curved surface printing system. The curved surface printing system comprises a circulating conveying track, a product aligning device, a printing device, a product taking-outdevice and a cleaning device are sequentially arranged on the conveying track, the conveying track is provided with a movable carrying table, and the printing device comprises a gravure rolling wheeland a soft transfer printing rolling wheel. According to the printing system, a curved surface product can be quickly printed, the printing quality is high, and the efficiency is high.

Description

technical field [0001] The invention belongs to the printing field, and more specifically relates to a curved surface printing system and method. Background technique [0002] Printing (Printing, Graphic Arts, also using Graphic Communications, that is, graphic communication) is to transfer text, pictures, photos, anti-counterfeiting and other manuscripts to paper, fabrics, plastics, etc. A technology that mass-reproduces the contents of original manuscripts on the surface of materials such as leather. [0003] Take printed curved glass as an example, such as Figure 1-4 As shown, the ink needs to be printed on the curved glass 1, and the ink is at the edge 2 of the curved glass. The current printing methods usually include the following methods: 1. Screen printing, such as figure 1 As shown, the screen plate 3 is usually planar, and it cannot print on the curved glass 1; 2, pad printing, such as figure 2 As shown, it has a pad printing pad 4, which is not easy to print ...

Problems solved by technology

[0003] Take printed curved glass as an example, such as Figure 1-4 As shown, the ink needs to be printed on the curved glass 1, and the ink is at the edge 2 of the curved glass. The current printing methods usually include the following methods: 1. Screen printing, such as figure 1 As shown, the screen plate 3 is usually planar, and it cannot print on the curved glass 1; 2, pad printing, such as figure 2 As shown, it has a pad printing pad 4, which is not easy to print on the side of the curved glass 1, and the printing thickness of the pad printing ink is relatively thin, which needs to go through multiple printing and baking procedures. The pad printing pad needs the product to stay It can be printed under it, and the time consumption increases; 3. Spray printing, such as image 3 As shown, utilize nozzle 5 to spray ink, and the ink sprayed on the height of curved surface glass 1 will flow from height to height, and the thickness is uneven, which is difficult to control; 4, photolithography, such as Figure 4 As shown, the curved glass 1 is printed through the mask plate 6 and the light source 7, but the photolithography manufacturing process is complicated (coating, exposure, development, etching, cleaning, etc.), and the cost is relatively high
