[0002] A printing press is a machine for printing text and images. It is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. The working principle is: first, the text and image to be printed are made into a printing plate and installed on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate. Existing printing presses supply ink through an automatic ink feeding device.

[0003] Patent CN110980618A (application number: 201911303216.4) discloses an automatic feeding device for packaging inkjet printer consumables. When filling ink, the packaging barrel is placed on the top load platform of the weighing sensor, and then the cylinder is opened to cover the barrel with a cover. The compression spring in the cylinder can act as a buffer to prevent the cover from damaging the packaging barrel. The controller opens the solenoid valve on the ink outlet pipe for ink filling.
