Problems solved by technology

However, this method requires the operator to manually apply silicone oil to the incision 25, which is inefficient and leads to higher production costs.
Moreover, since the application of silicone oil is prone to uneven application, the phenomenon of incision 25 sticking will still occur in the incision after applying silicone oil, and the qualified rate of the product is low
If more silicone oil is applied, it is easy to cause the silicone oil to dissolve into the ink, affecting the quality of the ink and printing quality

Abstract

The invention provides a one-way valve and a manufacturing method thereof as well as an ink box and a manufacturing method thereof. The one-way valve comprises a valve body formed by an elastic thin wall, wherein an opening is formed in one end of the valve body; a valve cavity communicated with the opening is arranged inside the valve body, and a cutting opening penetrating the inner surface and the outer surface of a side wall is formed in the side wall of the valve body; and an oxidation layer formed by oxidation of calcium chloride solution is formed on the section of the cutting opening. The manufacturing method for the one-way valve comprises the following steps: hot pressing is performed to form the valve body of the one-way valve, the opening is formed in one end of the valve body, and the valve cavity communicated with the opening is arranged inside the valve body; the cutting opening is formed by cutting in the side wall of the valve body, and penetrates through the inner surface and the outer surface of the side wall; and the one-way valve with the cutting opening is placed in 5% of calcium chloride solution for immersion for the predetermined time, and then the one-way valve is taken out from the solution, and dried in air. According to the invention, bonding of the cutting opening of the one-way valve can be greatly reduced, normal use of the one-way valve can be ensured, production efficiency of the one-way valve is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of printing, in particular to an ink cartridge installed on an inkjet printer, a manufacturing method of the ink cartridge, a one-way valve used in the ink cartridge and a manufacturing method of the one-way valve. Background technique [0002] Inkjet printers are common printers that provide great convenience for modern offices. Inkjet printers use an ink cartridge containing ink as a consumable container to eject ink onto paper to form text or patterns that need to be printed on the paper. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is shown with the chassis 11 omitted. The machine core 12 of ink-jet printer is provided with in the casing 11, and is provided with a slide bar 20, and printing word car 14 is in motor ( figure 1 (not visible in the middle) is driven to reciprocate along the slide bar 20. Printing word car 14 is provided with adapter plate (...
