Problems solved by technology

[0004] As mentioned above, the structure of the ink cartridge is relatively complicated, not only the cost of manufacture and use is high, but also has high requirements for the manufacturing process. The production of the ink cartridge needs multiple processes to complete, and the yield rate in the production process is low. The probability of failure during use is also higher
In addition, when this kind of ink cartridge is recycled and refurbished, the process is more complicated, and most of the ink bags with self-closing valves need to be renewed as a whole, and the cost is relatively high

Embodiment Construction

[0025] see figure 1 , The ink cartridge is composed of a housing 1 close to a cube and a cover 7 that seals its opening. The two can be sealed and connected by ultrasonic fusion welding, and the inside is an ink chamber. Seen from the position after installation, the front end has a circuit board base 2 for storing and reading out ink information from top to bottom, positioning plates 3 and 5 with positioning holes, ink outlet 4 and Trachea6. A circuit substrate that can maintain a good electrical connection with the relevant plug-in line in the printer box compartment can be fixed on the substrate seat 2. The ink outlet 4 and the air pipe 6 are also sealed and docked with the ink guide tube and the air pump tube in the box compartment respectively. The self-closing valve is immediately turned on, so that the ink outlet 4 is in the state of being able to supply ink to the ink pipe. When the print head needs to supply ink, the central processing unit of the printer will give a...

Abstract

The detachable ink cartridge for line printer includes one sealed casing to hold ink with air pipe, locating board and ink outlet on one side to be connected to the printer, self closing valve with outlet to be the said ink outlet and inlet in the lower part inside the ink cavity, non-return valve with inlet being the air pipe end and outlet in the high part inside the casing. The ink cartridge has relatively simple structure and this makes it possible to simplify the ink filling, cleaning and refilling. Without ink bag, the present invention has low cost and less environmental pollution.

Description

technical field [0001] The invention relates to an ink box for an inkjet printer, especially a detachable ink box for a large wide-line printer. Background technique [0002] One side of the wide-line inkjet printer frame is provided with a box compartment, the print head is connected to the box compartment through a pipe, and the ink cartridges of various colors are detachably placed in the box compartment. With the increasing application range of wide-line printers, wide-line printers The line width is also getting wider and wider. Since the print head moves back and forth in a direction perpendicular to the direction of motion of the printing medium, this makes the pipeline from the cartridge to the print head longer and longer. In order to solve the problem of ink in the pipeline The problem of insufficient ink supply due to pressure loss caused by pressure loss is to add air pressure to the ink cartridge, and rely on the air pressure to make the ink flow from the ink ca...
