[0047] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.
[0048] Example 1: An inkjet dyeing machine is disclosed, with reference to... Figure 1 The system includes a support frame, a fabric conveying mechanism, a first inkjet printhead 20, and a second inkjet printhead 30. The fabric conveying mechanism, the first inkjet printhead 20, and the second inkjet printhead 30 are all mounted on the support frame. The fabric conveying mechanism is used for conveying the fabric 10. The fabric conveying mechanism is an existing mechanism, typically including multiple drive rollers, a correction roller, a conveyor belt, and a drive assembly. The first inkjet printhead 20 and the second inkjet printhead 30 are spaced apart along the fabric conveying direction. In the fabric conveying direction, the first inkjet printhead 20 is located in front of the second inkjet printhead 30. The first inkjet printhead 20 is used to spray dye, and the second inkjet printhead 30 is used to spray fixing agent. That is, the fabric 10 first passes through the first inkjet printhead 20 for dye spraying, and then passes through the second inkjet printhead 30 for fixing agent spraying.
[0049] Both the second inkjet printhead 30 and the first inkjet printhead 20 have multiple printheads 50, the total spray range of which covers the entire width of the fabric 10. Each printhead 50 has multiple tiny nozzles 51. The physical resolution of the second inkjet printhead 30 and the first inkjet printhead 20 is 100 dpi-600 dpi. (Reference) Figure 7 The nozzles 51 of the nozzle 50 are arranged along the length of the nozzle 50; the length of the nozzle 50 is perpendicular to the fabric conveying direction. In other embodiments, refer to... Figure 8 The multiple nozzles 51 of the nozzle 50 are arranged along the length of the nozzle 50; the multiple nozzles 51 of the nozzle 50 are arranged along the length of the nozzle 50; the length of the nozzle 50 forms an angle b with the conveying direction of the fabric 10, where 0 degrees < b < 90 degrees or 90 degrees < b < 180 degrees.
[0050] The working principle of the second inkjet print head 30 and the first inkjet print head 20 is the same as that of the existing inkjet print head, and the inkjet flow thereof can be changed, wherein the inkjet flow is 30-3000 liters / hour; in addition, the number of nozzles used at the same time can also be changed. The second inkjet print head 30 and the first inkjet print head 20 adopt continuous inkjet, so as to adapt to different cloth conveying speeds.
[0051] In order to change the penetration ability of the second inkjet print head 30 and the first inkjet print head 20, the distance between the first inkjet print head 20 and the cloth 10 is adjustably arranged; the distance between the second inkjet print head 30 and the cloth 10 is adjustably arranged. The specific adjustment mode can be achieved by means of a linear driving element such as an electric cylinder or an air cylinder.
[0052] Reference Figure 5 In order to complete dyeing or fixing agent of the entire width of the cloth at one time, a plurality of nozzles 50 of the second inkjet print head 30 and the first inkjet print head 20 are arranged in parallel along the vertical direction of the cloth conveying direction, and the projection of the jetting range of the adjacent nozzles in the vertical plane of the cloth 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 cloth conveying direction is seamlessly connected, the liquid jetted by the adjacent nozzles has no overlap, so that there is no color difference (light and dark) at the splicing position of the adjacent nozzles of the cloth 10; when the projection of the jetting range of the adjacent nozzles in the vertical plane of the cloth conveying direction is partially overlapped, the liquid jetted by the adjacent nozzles has overlap, so that there is no gap white way at the splicing position of the adjacent nozzles of the cloth 10, which ensures that the jetting range of the inkjet print head is fully covered in the vertical direction of the cloth 10 conveying direction, thereby reducing the possibility of dyeing leakage. The one-pass inkjet dyeing equipment and method can greatly improve the efficiency of dyeing and the consistency of front and rear colors.
