Problems solved by technology

[0005] The present invention can solve the problem that the ink cannot be transferred to the printing plate due to blockage of part of the ink holes in the ink transfer process of the existing ink transfer roller, so that the printed product is different in depth at the front and shallow at the back; and the existing ink transfer roller The surface of the roller is in contact with the doctor blade, which will cause serious wear on the surface of the ink transfer roller for a long time, making it impossible to store and transfer ink, resulting in a slow supply of ink and affecting printing quality and other problems

Abstract

The invention provides a packaging printing ink transfer roller. The ink transfer roller comprises an outer executing unit and an ink transfer mechanism; the outer executing unit is of a left-right symmetric structure; and the ink transfer mechanism is arranged on the outer executing unit through a bearing. According to the ink transfer roller, the phenomenon that in an ink transfer process, ink cannot be transferred to a printing plate due to the fact that parts of ink holes of an existing ink transfer roller are blocked frequently, so that printing products are different in front and back color shade is avoided; and the problem that the surface of the existing ink transfer roller is in contact with an ink scraping knife and is seriously worn after a long time, the ink cannot be stored and transferred, the ink supply is not in time, and the printing quality is influenced is solved.

Description

Technical field [0001] The invention relates to the technical field of printing equipment, and in particular to a packaging printing ink transfer roller. Background technique [0002] The ink transfer roller is a reciprocating rubber roller that connects the ink fountain roller and the ink distribution part of the sheet-fed offset printing press. It receives the ink from the ink fountain roller and transfers it to the first ink transfer roller, and then goes through a series of horizontal and circumferential mixing, and finally The ink is transferred to the printing plate through the inking roller. [0003] During the ink transfer process of the existing ink transfer roller, some of the ink holes often become clogged, causing the ink to be unable to transfer to the printing plate, causing the printed products to appear darker at the front and lighter at the back; and the surface of the existing ink transfer roller is different from that of the printing plate. The contact be...
