Description

Inkjet printer and its ink replenishment tank and ink delivery device

technical field

The utility model relates to an inkjet printer, an ink supplement box and an ink delivery device. Specifically, the utility model provides an inkjet printer with a carriage or a carriage that slides reciprocally along the writing direction of the paper; An ink replenishment box for ink; and an ink delivery device that is fixedly installed on the carriage or carriage of the inkjet printer and transports the ink in the ink replenishment box to the recording head of the inkjet printer.

Background technique

Usually, the integral type ink box that recording head and ink box are arranged in the same body has limited ink storage capacity, and the ink storage capacity of the integrated type ink box that only accommodates monochromatic ink (for example black) is usually 20～50ml, and three-color ink (for example red, blue, Yellow) all-in-one ink cartridges usually have a storage capacity of 8-15ml for each color of ink. When the predetermined capacity of ink is exhausted, the circuit and nozzles of the recording head have not reached their designed service life, so the recording head scrapped together with the integrated ink cartridge is undoubtedly a great waste of resources and causes environmental pollution. Subsequent environmental protection treatment brings greater pressure; or due to ink drying after the ink cartridge has been vacant for a period of time, it brings cleaning troubles to the subsequent recycling of the integrated ink cartridge. On the other hand, the multi-color ink cartridge consumes unbalanced amounts of inks of each color. Therefore, when one color of ink is exhausted, it will affect the service life of the entire integrated ink cartridge and the image printing process, that is, the remaining ink of other colors will be larger. The all-in-one ink cartridge is completely scrapped, or the printing process is suspended, resulting in serious defects in the printed content. It can be seen that for a high-quality recording head, there is still a lot of space available for its design life compared with the ink consumption time of the integrated ink cartridge, or the ink storage capacity of the integrated ink cartridge should be fully considered.

Considering the above factors, the commercially available continuous ink supply system expands the ink storage capacity of the integrated ink cartridge. The technical means used is to increase the external ink storage mechanism, and transport the ink to the integrated ink cartridge through a series of ink delivery hoses. The integrated ink cartridge consumes ink during the printing process, and a negative pressure is formed inside the ink storage chamber, thereby generating a pressure difference between the external ink storage mechanism and the ink storage chamber of the integrated ink cartridge. In order to maintain pressure balance, the ink contained in the external ink storage mechanism flows to the ink storage chamber of the integrated ink cartridge through the ink delivery hose. When the life of the recording head is allowed, the ink storage capacity of the external ink storage mechanism can be considered in a larger value range, or the external ink storage mechanism can be replaced to ensure continuous ink supply for a longer period of time. In this way, the design life of the recording head can be fully utilized, the printing cost of the user can be reduced, and the pressure on environmental protection can be reduced.

CN02805167.1 domestic patent document discloses an ink supply device for a large inkjet printer. The unit includes: a cartridge with a storage bag, an ink supply tank and a solenoid valve. The cartridge with the storage bag is mounted in a rectangular parallelepiped casing, and ink is contained therein, having an ink outlet and an ink inlet at its front and rear ends, respectively. The ink outlet and the ink inlet are respectively integrally formed on the storage pack. On the lower side of the housing is mounted an operation switch which is operated by an operation panel integrally formed on one surface of the storage case to be in an on and off state. The ink supply tank stores a certain amount of ink, and is connected with the supply pipe through the ink inlet of the storage bag, so as to continuously replenish the ink to the storage bag by utilizing the drop. The solenoid valve is installed at an appropriate position of the supply pipe, and is connected with the operation switch so that the supply pipe is opened and closed by the on/off operation of the operation switch. The ink supply device does not need to replace the ink cartridge frequently, and has better economy and printing efficiency. However, the printers it is aimed at do not take into account the impact of the small printer box cover on the printer carriage or word carriage, and the pressure that it adopts to achieve ink due to the ink height difference that exists between the ink tank and the ink tank with the storage bag. The supply method cannot meet the negative pressure environment required for the recording head to work.

The formation method of the ink delivery hole 908 is basically the same as that of the vent hole 905 , both of which include a section of groove on the outer surface of the cartridge cover 901 sealed by a water-impermeable adhesive film 907 . One port of the ink delivery hole 908 communicates with the ink storage cavity 903 at the farthest end of the ink storage cavity 903 facing away from the cartridge cover 901 through a section of ink delivery pipeline 909. In FIGS. The bottom end, that is, its orientation is the same as that of the bottom 512 of the three-color integrated ink cartridge 51 for assembling the inkjet recording head. The other port of the ink delivery hole 908 communicates with the ink channel 910 passing through the ink storage chamber 903 and isolated from the ink storage chamber 903 . In the installed state, the ink channel 910 is in fluid-tight communication with the extension end of the second ink delivery tube 8014 protruding from the through hole 611 of the inkjet printer carriage gland, specifically the extension of the second ink delivery tube 8014. The end is inserted into the ink channel 910, and the liquid sealing method adopted is to use a sealing ring 911 to seal between the second ink delivery tube 8014 and the ink channel 910 (see Figures 14, 15, 16, 18). Therefore, in the state of use, the ink generally flows from the lowest level of the ink storage chamber 903 in the vertical direction to the ink delivery hole 908 located at a high position, and then flows to the ink channel 910 and the second ink delivery tube 8014 in sequence. The replenishment box for the other two-color inks of the three-color ink replenishment box 9 is similarly formed according to the structure described here, and will not be repeated here. The ink filling holes 913 for filling ink into the ink storage cavity 903 inside are respectively provided on the three-color ink replenishment box 9 box cover 901 and the water-tight adhesive film 907 and adopt a rubber pad 915 to give a seal.

Under the state of installation and use, the three-color integrated ink cartridge 51 and the black integrated ink cartridge 52 are respectively packed into the left case 41 and the right case 42 of the inkjet printer word cart. Afterwards, the ink delivery device 8 is plugged and fixed in the cover body of the inkjet printer character carriage gland 61 through the mortise and tenon buckles 8011, 8012, 8013 provided thereon, and the inkjet printer character carriage gland 61 is pressed down and It is fixed on the word cart 4 of the inkjet printer, so that the ends of the first ink delivery pipes 8031, 8032 and 8033 of the ink delivery device 8 are respectively inserted into the ink injection holes 5112, 5113 and 5114 of the three-color integrated ink cartridge 51 of the inkjet printer In the three-color integrated ink cartridge 51, the ink storage chambers of each color in the three-color integrated ink cartridge 51 are communicated with the corresponding ink delivery pipelines of the ink delivery device 8 in a one-to-one correspondence (the connection process of the monochrome integrated ink cartridge 52 is the same). Subsequently, the ink channel 910 of the three-color ink replenishment box 9 is connected in a liquid-tight manner with the extension end of the second ink delivery tube 8014 protruding from the through hole 611 of the carriage gland of the inkjet printer. So far, the three-color ink replenishment box 9 and the three-color integrated ink cartridge 51 of the inkjet printer are connected to each other through the ink delivery device 8 (the installation process of the monochrome ink replenishment box is carried out with reference to the installation process of the three-color ink replenishment box).

In this case, in order to better fix the ink replenishment box 9 on the inkjet printer character carriage 4, a positioning hole through itself is provided on the outer surface of the side wall of the box body 902 of the ink replenishment box 9 facing away from the box cover 901. 912, using an additional positioning plate 10 (see Figure 10), and making one end pass through the positioning hole 912, finally leaning against the vertical bottom of the inkjet printer character carriage 4, and finally reaching the bottom of the inkjet printer character carriage 4 In the vertical direction, the box body 902 is clamped by the top wall 9041 of the groove 904 and the positioning plate 10, and then the ink replenishment box 9 is fastened to the inkjet printer carriage 4. Here, the penetrating direction of the positioning hole 912 is the same as the printing sliding direction of the inkjet printer character carriage 4 .

According to the technical idea proposed by the utility model, relevant technical personnel can make improvements in many aspects with reference to its technical inspiration, and transfer this technical idea to other inkjet printers with similar structures, such improvements or technologies obtained based on the purpose of diversion The schemes all belong to the protection scope indicated by the claims of the utility model.
