Squeegee and ink return knife driving cylinder of a printing head

Abstract

The invention provides a driving air cylinder for a squeegee and an ink flooding blade of a printing head. The driving air cylinder comprises an air cylinder body, an ink flooding blade component, a squeegee component and an ink flooding blade sliding part. The driving air cylinder for the squeegee and the ink flooding blade of the printing head has the benefits as follows: the air cylinder is redesigned into a series connected two-section air cylinder, the total stroke is kept unchanged, the actuating stroke the air cylinder for regular actions is reduced, and the capacity is improved; besides, the air cylinder is redesigned into a three-sliding-table air cylinder mode, the actuating stroke of the air cylinder for regular actions is reduced to improve the capacity, the ink flooding blade only uses a single piston, which works cooperatively with a standard guide rail and a sliding block so as to bear the greatest stress load produced in the squeegee-printing process, and the guide rail of the squeegee is designed to be parallel with the squeegee stroke, and the rigidity is improved; moreover, a digital pressure gauge is arranged on the side wall of the air cylinder body, an electromagnetic valve group is arranged on the side wall symmetrical with the digital pressure gauge, a plurality of air cylinder speed control valves are arranged at the top of the air cylinder body, all the components are integrated in the air cylinder body, the following benefits are achieved: the quick response is achieved, the air course is the shortest, the actions are accurate, the least amount of air is compressed, matching pipes are reduced, the assembling time is reduced, and the pressure is displayed in real time.

Description

【Technical field】 [0001] The invention relates to the field of printing technology, in particular to a driving cylinder for scraping and ink returning knife of a printing head. 【Background technique】 [0002] At present, the printing machine is composed of a scraper and an ink return knife, which are set at a certain angle between them. The squeegee of the scraper and the ink return knife is flat. For ink return, there are many parts in the scraper assembly, the installation requires coordination and coordination, and the electromechanical control is complicated. 【Content of invention】 [0003] The purpose of the present invention is to solve the problem that at present, the printing machine is composed of a scraper and an ink return knife, and the two are arranged at a certain angle. The scraping rubber of the scraper and the ink return knife is flat. Then the ink is returned through the ink return knife. There are many scraper components, the installation requires coord...
