Automatic ink supply system for printing machine

Abstract

The invention discloses an automatic ink supply system for a printing machine. The automatic ink supply system comprises a printing roll set, an ink box and an ink supply pump, wherein an ink inlet pipe and an ink outlet pipe are respectively connected to the ink supply pump; a liquid level sensor is mounted in the ink box and is electrically connected with the ink supply pump through a controller; a plurality of openings are respectively formed in the front side of the ink box, a plurality of branch pipes are respectively connected to one side of the front end of the ink outlet pipe, front ends of the branch pipes respectively penetrate through the openings and extend into the ink box, and spray heads facing to the surfaces of roll bodies of the printing roll set are respectively connected to the front ends of the branch pipes. The automatic ink supply system is reasonable in structure; the ink supply pump is controlled by the liquid level sensor and the controller to automatically supply ink, and ink supplied into the ink box is sprayed to the surfaces of the roll bodies of the printing roll set by virtue of the spray heads, so that the fluctuation of the ink caused by the rotational inertia of the roll bodies of the printing roll set is avoided, resources are saved, the clean working environment is guaranteed, and the influence caused by the splashing of the ink to the printing quality is avoided.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to an automatic ink supply system for a printing machine. Background technique [0002] In the field of printing, the ink required for printing is usually supplied and supplemented by an oil supply pump, that is, an oil supply pump is set on one side of each printing area to pump ink to the ink cartridge. If the ink sent into the ink cartridge exceeds a certain liquid Under the influence of the force generated when the printing roller group rotates, the ink in the ink cartridge will fluctuate, and even overflow the ink cartridge, which not only causes waste, but also affects the working environment. Once it splashes on the surface of the paper, It will affect the printing quality. Contents of the invention [0003] The purpose of the present invention is to provide an automatic ink supply system for a printing machine. A liquid level sensor is installed in the ink box, and t...
