Scraper pressurizing device for printing machine

Abstract

The invention discloses a pressurizing device for a doctor blade of a printing machine, which comprises an ink chamber, the ink chamber and a rotating square shaft are fixed as a whole through a plurality of positioning plates, the ink chamber is parallel to the rotating square shaft, and bearings are installed at both ends of the rotating square shaft On the M-side mounting plate and the G-side mounting plate at both ends, swing arms are respectively provided at both ends of the rotating square shaft. The swing arms are connected to the cylinder, and the cylinder is fixed on the rear support of the cylinder. Screws are fixed on the back of the rotating square shaft, and the other end of each positioning plate is provided with a U-shaped opening slot, which is close to the ink chamber, and a small shaft is inserted between the U-shaped opening slot and the ink chamber to make the U-shaped opening The tank and the ink chamber are fixed as a whole, and each small shaft is equipped with a hand wheel, which is used to lock or loosen the ink chamber and the positioning plate, and tighten the hand wheel to securely fix the ink chamber and the rotating square shaft. It solves the problems in the prior art that it is troublesome to pressurize and adjust the pressure of the scraper in the scraper device, and it is inconvenient to disassemble the ink cavity and the ink seal is not easy to adjust.

Description

technical field [0001] The invention belongs to the technical field of printing machinery, and in particular relates to a pressurizing device for a printing machine scraper. Background technique [0002] The scraper device of the printing machine is mainly composed of the ink chamber and the pressurizing mechanism. The ink chamber needs to realize the clutch with the anilox roller. At the same time, the ink chamber can be disassembled as a whole for replacement. The pressurizing mechanism can fix the ink chamber and realize the connection between the ink chamber and the anilox roller. The clutch of the anilox roller, the pressurization method of the scraper of the printing machine is usually divided into three types: pneumatic, hydraulic and mechanical. The pneumatic and hydraulic types use air pressure and oil pressure to pressurize the scraper. The mechanical type is a structure in which the scraper advances and retreats manually, but these three methods are troublesome to...
