[0042] The following description will be made in conjunction with the accompanying drawings Figures 1-6 The present application will be described in further detail.

[0043] Embodiment one: disclose a kind of inkjet dyeing machine, reference Figure 1 , including support, cloth conveying mechanism, first inkjet print head 20, drying assembly 40 and second padding assembly 60;Cloth conveying mechanism, first inkjet print head 20, drying assembly 40 and second padding assembly 60 are all set in support;Cloth conveying mechanism is used for the conveying of cloth 10;Cloth conveying mechanism is prior mechanism, it usually includes multiple transmission roller, correction roller, conveying mesh belt and drive assembly;First inkjet print head 20, drying assembly 40 and second padding assembly 60 are sequentially arranged along the cloth conveying direction;Wherein first inkjet print head 20 is used to spray dye liquor, drying assembly 40 is used to dry cloth 10;Second padding assembly 60 is used for cloth fixing agent padding;That is, cloth 10 first passes through first inkjet print head 20 and is sprayed with dye liquor, then passes through drying assembly 40 and is dried, and then second padding assembly 60 is padded with fixing agent.

[0044] First inkjet print head 20 has multiple nozzles 70, and the spraying range of multiple nozzles 70 covers the entire width of cloth 10, nozzle 70 has multiple tiny nozzles 71, and the physical resolution of first inkjet print head 20 is 100dpi-600dpi.Reference Figure 5 , multiple nozzles 71 of nozzle 70 are arranged along the length direction of nozzle 70;The length direction of nozzle 70 is perpendicular to the conveying direction of cloth 10.In other embodiments, reference Figure 6 , multiple nozzles 71 of nozzle 70 are arranged along the length direction of nozzle 70;Multiple nozzles 71 of nozzle 70 are arranged along the length direction of nozzle 70;The length direction of nozzle 70 is at angle b with the conveying direction of cloth 10, 0 degrees <b<90 degrees or 90 degrees <b<180 degrees.

[0045] The first inkjet print head 20 works in the same way as the existing inkjet print head, and the inkjet flow rate can be changed, wherein the inkjet flow rate is 30-3000 liters / hour; in addition, the number of nozzles used at the same time can also be changed. The first inkjet print head 20 uses continuous inkjet, which can adapt to different fabric conveying speeds.

[0046] In order to change the penetration ability of the first inkjet print head 20, the distance between the first inkjet print head 20 and the fabric 10 is adjustably arranged. The specific adjustment method can be achieved by means of a linear drive such as an electric cylinder, an air cylinder, etc.

[0047] Reference Figure 3 In order to complete the dyeing or fixing agent of the entire width of the fabric at one time, a plurality of nozzles 70 of the first inkjet print head 20 are arranged in parallel along the vertical direction of the fabric conveying direction, and the projection of the jetting range of the adjacent nozzles in the vertical plane of the fabric conveying direction is seamlessly connected or partially overlapped. When the projection of the jetting range of the adjacent nozzles in the vertical plane of the fabric conveying direction is seamlessly connected, the liquid jetted by the adjacent nozzles does not overlap, so that there is no color difference (light and shade) at the splicing position of the adjacent nozzles of the fabric 10; when the projection of the jetting range of the adjacent nozzles in the vertical plane of the fabric conveying direction is partially overlapped, the liquid jetted by the adjacent nozzles overlaps, so that there is no gap white way at the splicing position of the adjacent nozzles of the fabric 10, which ensures that the jetting range of the inkjet print head is fully covered in the vertical direction of the fabric 10 conveying direction, thereby reducing the possibility of dyeing leakage. This ONE PASS inkjet dyeing device and method can greatly improve the efficiency of dyeing and the consistency of the front and rear colors.

[0048] In other embodiments, reference Figure 4 The plurality of nozzles 70 are arranged in a staggered manner along the fabric 10 conveying direction, and the projection of the jetting range of the adjacent nozzles in the vertical plane of the fabric 10 conveying direction is seamlessly connected or partially overlapped.

[0049] The drying assembly 40 is a prior art, which generally includes a drying box and a drying component, and the drying component is arranged in the drying box and uses electric heating, gas heating, light heating or steam heating; in order to make the drying uniform, the drying box generally also has a hot air circulation component to make the heat uniform. The role of the drying assembly 40 in this embodiment is to solidify the dyeing liquid before the fixing agent padding, so as to avoid the dyeing liquid from entering the second padding assembly 60 to contaminate the fixing agent.

[0050] The second padding assembly 60 is a common padding device, including a padding box and a padding roller; the padding roller includes an upper pressure roller and a lower pressure roller located in the padding box; the fabric passes through between the upper pressure roller and the lower pressure roller. Since the inkjet print head is a high-precision device, the cost is relatively high, while the padding device is relatively simple and low in cost; at the same time, the dyeing adopts the padding device, and the fixing uses the inkjet print head, which is more water-saving, energy-saving and environmentally friendly compared with using the padding device for dyeing and fixing.

[0051] Embodiment two: the difference between embodiment two and embodiment one is that: Figure 2 , using the second inkjet print head 30 instead of the first inkjet print head 20 as the dyeing assembly, the second inkjet print head 30 is used for spraying the fixing agent; using the first padding assembly 50 instead of the second padding assembly 60 as the padding assembly, the first padding assembly 50 is used for fabric dyeing, that is, the fabric 10 is dried after completing the fixing agent spraying, and then the padding of the dyeing liquid is carried out. The structure of the second inkjet print head 30 is the same as that of the first inkjet print head 20; the structure of the first padding assembly 50 is the same as that of the second padding assembly 60.

[0052] All the above embodiments are applied to the fixing agent, but in fact they can also be applied to other auxiliaries, such as synergists, waterproof agents, antibacterial agents, sunscreen agents, fireproof agents, etc.

[0053] The above are preferred embodiments of the present application, not limited to the protection scope of the present application, therefore: all equivalent changes made according to the structure, shape and principle of the present application should be covered in the protection scope of the present application.
