The scraper can be connected with a scraper moving handle, and the scraper moving handle is only pushed when ink is scraped, so that the scraper is convenient and labor-saving.

The method can screen-print two opposite edges of the large-layout glass, after one edge is screen-printed, the glass is pushed forward and then screen-printed on the other edge, if the width of the later colored glaze screen-printed is narrower, an adhesive tape can be pasted on the glass in advance, and the adhesive tape can be torn off after the screen-printing is finished by using the previous narrow-mesh plate.

Aiming at the process production line of the method, a conveying platform B can be added on the other side of the small-sized screen printer, so that the support of the glass is convenient during the screen printing of the edge patterns on the opposite side, and simultaneously the glass after the edge color glaze screen printing is conveyed to the next process, especially to a toughening furnace. The conveying platform B is placed at the front section of the toughening furnace to form a connecting line for use, and the efficiency is improved.

Compared with the existing silk-screen printing method, the method of the invention has the following advantages: 1. the width of the narrow screen printing plate is manufactured according to the width of the colored glaze at the edge part, a large screen printing plate of a whole piece of glass does not need to be covered, the waste of the screen printing plate is reduced, meanwhile, the waste of ink is also reduced, no matter how narrow the colored glaze at the edge part is, the large screen printing plate needs to be coated with the full screen printing plate when being coated with the ink, and an ink scraper can move the full screen printing plate. 2. The edge grinding machine has the advantages of small occupied area, field saving, simple adjustment, flexibility, convenience, no space limitation, capability of directly printing the sheet platform with a width of about one meter left after edge grinding, direct tempering after printing, and particular suitability for line connection production. 3. Personnel are reduced, and compared with a production line, the manual printing machine can finish the work of printing, trimming and the like by only three persons. 4. The printing efficiency is high, and especially, the useless stroke of printing in the middle of the glass is reduced by the colored glaze glass at the edge of the large glass plate.
