Embodiment Construction

[0045] The invention provides a screen printing nozzle device, which can transfer the liquid printing material to the printed matter on the printing platform through the screen. The screen is usually a net-like material, such as cotton silk cloth and silk silk cloth. Or metal mesh, etc., and the present invention can not only be applied to general screen printing, but also can be used for film formation and polarization of plastics.

[0046] Such as figure 1 As shown, it is a schematic diagram of a first embodiment of the screen printing nozzle device of the present invention. Platform 16 and a screen plate 18, wherein scraper 122 and ink return knife 124 are relatively arranged, and the middle gap feeding of the two in the printing material is therefore equivalent to scraper 122 and ink return knife 124 and has formed injection cylinder 12, and feeding The mouth 126 is provided with a thread 28; the heater 14 is arranged on the outside of the injection cylinder 12, and in a ...

Abstract

The invention provides a screen printing nozzle device. According to the screen printing nozzle device, a scraper and an ink returning knife are oppositely arranged, and the gap between the scraper and the ink returning knife can be used for material injection, so that the scraper and the ink returning knife can form an injection cylinder; a heater is arranged on the outer side of the injection cylinder; after liquid or solid printing materials are injected into the injection cylinder, the printing materials flow out of a discharge port at the bottom of the injection cylinder to a screen plateplaced on a printing platform after being thawed out or melted by the heater, and the injection cylinder reciprocates on the printing platform; and because a printed matter is placed on the printingplatform, when the printing materials flow onto the screen plate, the scraper applies pressure on the screen plate to print the printing materials onto the printed matter through the screen plate. Because the scraper, the ink returning knife and the injection cylinder are integrally designed, and the scraper and the ink returning knife can also be used as electrodes, after the printing platform iselectrically connected with a power supply, the application range is expanded to plastic film forming and polarization processing. Printing and polarization are integrated on the same machine platform, so that space and polarization time are saved.

Description

technical field [0001] The invention relates to an inkjet device, in particular to a screen printing nozzle device used in screen printing. Background technique [0002] The screen printing machine is mainly composed of a transmission device, a printing plate device, a printing device, a printing platform, a plate alignment mechanism, a drying device, and an electrical control device. The ink scraping and ink return of the printing device are the main actions of screen printing. The ink scraping system and the ink return system are usually installed on the scraper carriage. During the reciprocating motion, the scraper and the ink return knife rise and fall alternately The actions of ink scraping and ink return are respectively realized. The printing material is pressed by the scraper and passed through the screen to print on the printing platform. When the ink is returned, the excess printing material will be scraped back to the original position by the ink return knife for ...
