Problems solved by technology

An inlet is set on the main ink tank in the prior art, and it is sealed with an ink cartridge cover. The ink cartridge cover is provided with an ink outlet joint, an air intake joint and a liquid level sensor. If the ink in the main ink tank is insufficient, the following two methods are usually adopted: Ink replenishment: one way is to add ink to the main ink tank, and the other way is to replace the main ink tank; when adding ink, the ink tank cover needs to be unscrewed, and the various joints set on it should be removed at the same time. When replacing the main ink tank, it is also necessary to unplug the pipeline on the ink cartridge, and then reconnect after replacing the main ink tank. Both operations need to stop the printer so that there is enough time to connect the connector and the liquid level sensor. Avoid ink supply being affected, which will affect the printing progress and output, printing interruption may even affect the printing quality

Abstract

The continuous ink supply device for the printer comprises an ink supply box, a main ink tank is arranged on the lower portion of the ink supply box, and a liquid level sensor is arranged in the main ink tank; an ink supplementing device is installed above a main ink tank in the ink supply box, the ink supplementing device can move back and forth relative to the ink supply box, the ink supplementing device comprises an installation frame, the installation frame is provided with a containing groove corresponding to the main ink tank in position, and the containing groove is used for containing an ink supplementing ink box. When the installation frame moves backwards to a limit position, an ink outlet of the ink supplementing ink box placed on the containing groove corresponds to an ink inlet of the main ink tank in position. The ink supply box is internally provided with a hole breaking device, and the hole breaking device is used for puncturing a sealing layer at an ink outlet of the ink supplementing ink box so that ink in the ink supplementing ink box can flow into the main ink tank. The ink supply device has the beneficial effects of guaranteeing continuous ink supply of the printing spray head, being convenient to operate, high in practicability and high in reliability.

Description

technical field [0001] The invention relates to the technical field of inkjet printing equipment, in particular to a continuous ink supply device for a printer. Background technique [0002] In order to ensure the continuous and stable supply of ink to the print nozzles in existing inkjet printers, secondary ink cartridges are often installed on the printing carriage. The ink flows from the main ink tank into the secondary ink cartridges, and then the secondary ink cartridges supply the ink to each print nozzle. The secondary ink box is connected with the negative pressure device, so that there is a constant negative pressure value in the secondary ink box to ensure the stability of ink supply; there is a liquid level sensor in the secondary ink box to detect the amount of ink in the secondary ink box , so that when the secondary ink tank is short of ink, ink can be replenished from the main ink tank to the secondary ink tank in time. An inlet is set on the main ink tank in...
