The following is a detailed introduction to the ink invoice printing machine: The working principle of the ink invoice printing machine is mainly based on printing technology. Through the interaction between the image and the ink on the printing plate, the required content is printed on the invoice. Specifically, the concave and convex patterns on the printing plate will combine with the ink to form a transferable ink surface. When the printing plate contacts the invoice paper, the ink will be transferred to the paper, thus completing the printing process.

[0003] During the use of the ink invoice printing machine, it is necessary to frequently add ink into the printing machine to ensure the uniformity of printing. The existing method uses a shovel to deliver the ink in the barrel to the ink feeding position. In this way, some dust and impurities are easily mixed into the ink during the feeding process, and the printing quality cannot be guaranteed during the printing process. At the same time, the manual ink feeding method also increases the labor intensity. In view of this, we provide an ink feeding mechanism for an invoice printing machine to solve the above problems.
