Ink storage unit

Abstract

The utility model discloses an ink storage unit which comprises an ink bag used for storing ink and an adapter installed at the front end of the ink bag, and the installation direction of the ink storage unit installed in an ink-jet printer is parallel to the length direction of the ink storage unit. In the installation direction, the ink bag comprises an ink storage chamber located on the front side and an auxiliary containing part located on the rear side. The auxiliary containing part is a solid sheet or an ink storage bin which is thinner than the ink storage chamber. When the auxiliary storage part is made of the solid sheet, an exhaust hole does not need to be reserved in the auxiliary storage part, the machining process is simplified, the production cost is reduced, and the winding resistance is small. When the auxiliary containing part is an ink storage bin with the thickness smaller than that of the ink storage chamber, the ink storage capacity can be increased while the winding quality is guaranteed.

Description

[0001] This utility model claims the priority of a prior Chinese application with an application date of April 20, 2023, an invention title of "Ink Storage Unit", and an application number of CN2023209117000. All the content of the prior application is incorporated herein by reference in its entirety. Technical Field

[0002] This utility model relates to the field of inkjet printing, and particularly to an ink storage unit for an inkjet printer. Background Art

[0003] Existing inkjet printers supply ink through replaceable ink storage units.

[0004] Patent application US20230057827A1 discloses an ink storage unit for an inkjet printer, which has an ink sac for storing ink and an adapter installed at the front end of the ink sac. The adapter is provided with an ink delivery channel for delivering the ink in the ink sac to the ink pickup needle of the inkjet printer. The inkjet printer is provided with a drawer-type carrier box. Positioning bosses are provided on both sides of the carrier box along the width direction. Positioning grooves cooperating with the positioning bosses are provided on the adapter of the ink storage unit. An outwardly convex arc surface is configured on the positioning boss, and an inwardly concave arc surface is provided on the positioning groove. When the positioning boss is inserted into the positioning groove, the outwardly convex arc surface cooperates with the inwardly concave arc surface to horizontally position the adapter in the carrier box. Along the height direction of the ink storage unit, the ink sac is formed by joining a first sheet body located on the upper side and a second sheet body located on the lower side. Along the length direction of the ink storage unit, that is, the installation direction in which the ink storage unit is installed in the inkjet printer, the ink storage cavity is located on one side of the frame close to the adapter, and the non-ink storage cavity is located on the side away from the adapter frame. The periphery of the ink storage cavity is sealed by welding. An air hole communicating with the outside is provided on the side of the non-ink storage cavity sac body close to the adapter, and the non-ink storage cavity is exhausted through the air hole. This ink sac structure wastes materials and space, and has a relatively high processing cost. A winding roller that can roll along the installation direction is provided on the carrier box. One end of the ink sac away from the adapter is fixed to the winding roller by a clip, and the winding roller winds up the ink sac when rolling along the installation direction. Summary of the Utility Model

[0005] This utility model aims to provide an ink storage unit with a simple structure.

[0006] To achieve the above object, in the first aspect of this utility model, an ink storage unit is provided, which includes an ink sac for storing ink and an adapter installed at the front end of the ink sac. The installation direction in which the ink storage unit is installed in the inkjet printer is parallel to the length direction of the ink storage unit. Along the installation direction, the ink sac includes a front-side ink storage chamber and a rear-side auxiliary storage part; the auxiliary storage part is a solid sheet material.

[0007] Thus, when the auxiliary storage part is a solid sheet, there is no need to reserve exhaust holes on the auxiliary storage part, which simplifies the processing technology, reduces the production cost, and has a smaller winding resistance. When the auxiliary storage part is an ink storage bin with a thickness smaller than that of the ink storage chamber, the ink storage capacity can be expanded while ensuring the winding quality.

[0008] Furthermore, the ink storage chamber is formed by joining a first sheet located on the upper side and a second sheet located on the lower side. The auxiliary storage part is a solid sheet and is fixed between the first sheet and the second sheet.

[0009] Furthermore, the ink storage chamber is formed by joining a first sheet located on the upper side and a second sheet located on the lower side. The part of the first sheet that is longer than the second sheet serves as the auxiliary storage part.

[0010] Furthermore, the ink storage chamber is formed by joining a first sheet located on the upper side and a second sheet located on the lower side. The parts of the first sheet and the second sheet that extend beyond the ink storage chamber on the side away from the adapter are joined together to form the auxiliary storage part.

[0011] Furthermore, a sandwich layer is provided in the auxiliary storage part. The parts of the first sheet and the second sheet that extend beyond the ink storage chamber on the side away from the adapter are joined together with the sandwich layer to form the auxiliary storage part.

[0012] Furthermore, the first sheet, the second sheet and the auxiliary storage part are fixedly connected by bonding or welding.

[0013] In a second aspect of the present invention, there is provided an ink storage unit, including an ink sac for storing ink and an adapter installed at the front end of the ink sac. The installation direction of the ink storage unit into an inkjet printer is parallel to the length direction of the ink storage unit. Along the installation direction, the ink sac includes an ink storage chamber located on the front side and an auxiliary storage part located on the rear side; the auxiliary storage part is an ink storage bin with a thickness smaller than that of the ink storage chamber.

[0014] Furthermore, the auxiliary storage part includes an ink storage bin and a reinforcement sheet fixed on the ink storage bin.

[0015] Furthermore, the ink storage chamber and the ink storage bin are formed by joining a first sheet located on the upper side and a second sheet located on the lower side.

[0016] Furthermore, along the installation direction, the rear end of the auxiliary storage part is fixed on the winding roller of the carrier box of the inkjet printer by bonding, welding, riveting or clamping. This fixing method is simple, reliable, easy to operate and has a low cost. Description of the Drawings
