Squeegee separating device for printing machine

Abstract

The invention provides a scraper separating device for a printing machine, and mainly relates to the field of printing equipment. The scraper separating device for the printing machine comprises a track, a mounting rack, a main installing position, an auxiliary installing position, scraper carrying frames, scrapers, elastic bodies, a propelling device and a control device, wherein the track is installed on a printing device; the bottom of the mounting rack is a sliding part, and the sliding part is connected with the track in a sliding mode; the two scraper carrying frames are located in the main installing position and the auxiliary installing position respectively; clamping grooves are arranged in the two sides of the scrapers; the plurality of elastic bodies are arranged between the scrapers and fixed plates of the scraper carrying frames; the propelling device is used for driving the mounting rack to slide in the track; and the control device is electrically connected with the propelling device. The scraper separating device for the printing machine has the beneficial effects that the scrapers can be separated and replaced without stopping, the normal production progress is notinfluenced, and the situation of printing errors caused by restarting of equipment is avoided.

Description

technical field [0001] The invention mainly relates to the field of printing equipment, in particular to a scraper separation device for a printing machine. Background technique [0002] A scraper is a thin sheet used on a printing press to scrape off excess ink on the surface of the cylinder. In each printing process, removing ink from the non-patterned area on the cylinder is a critical step. The shape, material and specification of the scraper can be selected differently according to the type of printing, the printing substrate and the characteristics of the ink. When printing with an offset printing machine with paste ink, plastic or resin scrapers are usually used to achieve a better ink scraping effect, but scrapers made of these materials usually have poor wear resistance. In order to ensure normal production , the scraper needs to be replaced frequently, and once the machine is shut down to replace the scraper, the production progress will be affected, and the stop ...

Problems solved by technology

When printing with an offset printing machine with paste ink, plastic or resin scrapers are usually used to achieve a better ink scraping effect, but scrapers made of these materials usually have poor wear resistance. In order to ensure normal production , the scraper needs to be replaced frequently, and once the machine is stopped to replace the scraper, the production progress will be affected, and the equipment may be stopped and turned on, which may cause the misalignment of the printed pattern, which will further affect the subsequent production
