Description

Energy-saving screen printer

Technical Field

The utility model relates to the technical field of printing, in particular to an energy-saving screen printer.

Background

The screen printing machine is a machine for printing by using screen printing plate, belonging to a kind of printing machine. A screen printer is a machine that prints characters and images, and is a generic name of a machine or apparatus for producing printed matters. The screen printing machine belongs to the representative printing equipment in the porous printing machine, and the material for manufacturing the screen can be nylon wire, copper wire, steel wire or stainless steel wire besides real silk. And can be classified into a flat screen printer, a curved screen printer, a rotary screen printer, and the like.

The screen printing machine has the working principle that the ink scraping plate extrudes ink and a screen printing plate in motion to enable the screen printing plate and a printing stock to form a press nip, the screen has tension N1 and N2 to generate force F2 to the ink scraping plate, the resilience force enables the screen printing plate not to be in contact with the printing stock except the press nip, and the ink is leaked to the printing stock from the moving press nip through the meshes under the action of the extrusion force F1 of the ink scraping plate. In the printing process, the screen printing plate and the ink scraping plate move relatively, the extrusion force F1 and the resilience force F2 also move synchronously, and the screen returns to be separated from the contact with the printing stock in time under the action of the resilience force so as to avoid smearing the print. After finishing unidirectional printing, the ink scraping plate and the screen printing plate are separated from a printing stock, and meanwhile, ink is returned in a return process, namely, a printing cycle is finished.

However, when the ink scraping plate extrudes the ink in the process, the redundant ink can move to the edge of the screen printing plate along with the ink scraping plate, and the ink accumulated on the edge of the screen printing plate can be gradually thickened in the long term, so that the normal printing is prevented from being influenced, the ink needs to be scraped regularly, the scraped ink cannot be reused, and resources are wasted.

Therefore, a new solution is needed to solve this problem.
