Reciprocating motion type sealed ink fountain of printing or coating machine

Abstract

The invention discloses a reciprocating motion type sealed ink fountain on a printing or coating machine. The reciprocating motion type sealed ink fountain on the printing or coating machine solves the problems that an existing sealed ink fountain are fixed, a scraper and an anilox roller on the existing sealed ink fountain are also fixed, so that the scraper has a high change frequency, printingcost is increased, and scraper consumption is serious, and other problems are also solved. According to the technical scheme, the reciprocating motion type sealed ink fountain on the printing or coating machine comprises an ink fountain frame for being fixed on the printing or coating machine and a sealed ink fountain arranged on the ink fountain frame. The reciprocating motion type sealed ink fountain is characterized in that the sealed ink fountain is matched on the ink fountain frame in a transversely sliding mode and is positioned at the front side of the ink fountain frame; a reciprocating motion driving mechanism is mounted on the ink fountain frame; and the driving end of the reciprocating motion driving mechanism is connected with the sealed ink fountain.

Description

technical field [0001] The invention relates to an ink fountain on a printing or coating machine, in particular to a reciprocating closed ink fountain on a printing or coating machine. Background technique [0002] The ink fountains on printing or coating machines commonly used at present can be divided into two categories: one is the open ink fountain, the ink or paint in the ink fountain is transferred to the anilox roller by the ink fountain rubber roller, the scraper contacts the anilox roller, and the scraper and the ink fountain Each is a separate component; the second is a closed ink fountain, and the scraper is fixedly installed on the ink outlet on one side of the ink fountain. The ink fountain directly contacts the anilox roller from one side of the ink outlet, and the scraper also contacts the anilox roller at the same time. [0003] The above-mentioned closed ink fountain can be divided into fully enclosed ink fountain and semi-closed ink fountain. The ink chambe...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the problems that the existing closed ink fountains are all fixed, and the doctor blade on it is also in fixed contact with the anilox roller, resulting in a high frequency of replacement of the doctor blade, increased printing costs and serious consumption of the doctor blade, etc., the purpose of the present invention is to provide an improved The reciprocating motion type closed ink fountain on the printing or coating machine can overcome the defects of the prior art
