[0002] A digital printing machine is a device that uses digital technology for direct inkjet printing and is widely used in textiles, clothing, home decoration, advertising and other fields. Compared with traditional printing processes, digital printing machines have the advantages of high flexibility, short production cycle and environmental protection. Its principle is to use a computer to control the inkjet system to print the designed pattern directly onto fabric or other materials.

[0003] The ink of existing digital printing machines is generally transported from large-capacity ink cartridges to the nozzles through pipes for continuous ink supply, which is suitable for long-term continuous production. However, over time, layers of solidified ink will appear in the pipes, which will in turn affect the ink output and be detrimental to the inkjet efficiency of the digital printing machine. Therefore, an ink supply device for a digital printing machine is proposed to improve the existing problems. Utility Model Content

[0021] Among them, when it is necessary to perform inkjet printing on the surface of the fabric, the electric slider 21 can be started, so that the electric slider 21 drives the displacement box 2 to slide along the opening direction of the slide rail 22, so that the inkjet box 3 in the displacement box 2 can pass through the conveying pipe 4, the connecting channel 5 and the inkjet head 6 to perform inkjet printing on the surface of the fabric; in this process, the heating element 8 is started to heat the outer wall of the conveying pipe 4, thereby avoiding the problem of layers of solidified ink in the pipe, which will affect the ink output, and thus ensure the ink output, thereby improving the inkjet efficiency of the digital printing machine.

[0022] It should be noted that the utility model uses white grey cloth produced by warp knitting and purchased white grey cloth. First, the grey cloth must be pre-shaped. The cloth heating temperature is 180-190°C, and the grey cloth speed is controlled at 30-50m / min. The grey cloth is pre-shaped on a shaping machine to maintain the dimensional stability and finishing appearance of the grey cloth. Through shaping, the fibers inside can be arranged in a regular and directional manner, which ensures that the fiber core is less corroded during the subsequent processing, and does not affect the alkali corrosion of the fiber outer layer.

[0023] See Figures 1-4Furthermore, a cavity 23 is provided in the displacement box 2, and a through hole 24 is provided at the bottom of the cavity 23. The inkjet cartridge 3 is located in the cavity 23, and the end of the delivery pipe 4 away from the inkjet cartridge 3 extends outside the displacement box 2 through the through hole 24 and is connected to the connecting channel 5; a fixing bar 71 is provided on the side wall of the ear plate 7, and the end of the fixing bar 71 away from the ear plate 7 is connected to the side wall of the connecting channel 5.

[0024] Among them, multiple inkjet cartridges 3 of different colors can be placed in the cavity 23, and the delivery pipes 4 corresponding to different inkjet cartridges 3 can also extend outside the displacement box 2 through the through hole 24 and be connected to the connecting channel 5, thereby improving practicality.
