Automatic ink feeding device for printing machine

Abstract

The invention discloses an automatic ink feeding device for a printing machine. The automatic ink feeding device for the printing machine comprises an ink pumping device, a mixing device, a fixing device, an ink feeding device and an ink storage box. The ink pumping device comprises an ink barrel, an ink pumping pump and a base. Flange plates distributed parallelly are arranged on ink pipelines, rubber skin pads are arranged on the inside surface of the flange plates, the mixing device is arranged on the ink pipelines, and the mixing device comprises a mixing box and an impurity storing box. The ink feeding device comprises a cylinder body, an ink feeding valve is arranged at the top end of the inner of the cylinder body, a telescopic spring is connected to the bottom of the ink feeding valve, a floating ball is fixedly connected to the other end of the telescopic spring, a connecting rod is arranged on the floating ball, and a floating ball valve is arranged at the other end of the connecting rod. The floating ball valve is arranged on a sliding rod, and an irk discharging valve is arranged at the bottom of the sliding rod. The design of the flange plates is convenient to disassemble and install and convenient to clean the ink pipelines, the mixing device achieves the purposes of mixing and removing impurity, meanwhile, the ink feeding device achieves the purpose of automaticink feeding, manual operation with one barrel to one barrel is not required, and the efficiency is improved.

Description

technical field [0001] The invention relates to an ink filling device, in particular to an automatic ink filling device for a printing machine. Background technique [0002] Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Printing onto paper or other substrate to reproduce the same print as the printing plate. [0003] Most of the existing printing machines use manual ink filling to add ink to the printing machine. The operation is cumbersome and complicated, which greatly reduces the printing speed. In the case of a large number of printing, frequent ink addition is required, and the labor intensity i...

Problems solved by technology

[0003] Most of the existing printing machines use manual ink filling to add ink to the printing machine. The operation is cumbersome and complicated, which greatly reduces the printing speed. In the case of a large number of printing, frequent ink addition is required, and the labor intensity is high, which reduces the production efficiency.
