Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing and dyeing technology, and in particular to an inkjet dyeing machine. Background Technology
[0002] Current dyeing methods generally involve immersion or pad dyeing. The fabric is first dyed in a dye vat, and then a curing agent is applied to the fabric for curing through immersion or coating. This results in a large amount of dye and curing agent being used, which is much greater than the actual amount of dye required for the fabric, leading to waste of dye and curing agent. Since both dye and curing agent pollute the environment, they are not environmentally friendly and greatly increase the cost of subsequent recycling and treatment. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an inkjet dyeing machine with the advantages of energy saving and environmental protection.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An inkjet dyeing machine includes a pad-dyeing component and a spray-dyeing component; the pad-dyeing component and the spray-dyeing component are arranged sequentially along the fabric conveying direction; the pad-dyeing component is a first pad-dyeing component or a second pad-dyeing component; the first pad-dyeing component is used for pad-dyeing the fabric with dye liquor; the second pad-dyeing component is used for pad-dyeing the fabric with a color-fixing agent; the spray-dyeing component is a first inkjet printhead or a second inkjet printhead; the first inkjet printhead is used for spraying dye liquor onto the fabric; the second inkjet printhead is used for spraying a color-fixing agent onto the fabric; the fabric sequentially passes through the second pad-dyeing component and the first inkjet printhead or the first pad-dyeing component and the second inkjet printhead.
[0006] By adopting the above technical solution, at least one of the dye solution and fixing agent is used for printing and dyeing through the inkjet printhead, which effectively reduces the waste of dye solution and fixing agent, and saves energy and is environmentally friendly.
[0007] Optionally, a drying component is provided between the dyeing liquor dyeing assembly and the fixing agent dyeing assembly; the drying component is used to dry the fabric.
[0008] By adopting the above technical solution, the drying component allows the dye or fixing agent on the fabric to be dried and cured, reducing the impact on subsequent processes.
[0009] Optionally, the drying assembly includes a drying chamber and a drying component, wherein the drying component is disposed inside the drying chamber and the drying component uses electric heating, gas heating, light heating or steam heating.
[0010] By adopting the above technical solution, the fabric is dried by the drying components as it passes through the drying box, and the drying process is not affected by the external environment.
[0011] Optionally, the distance between the dyeing component and the fabric can be adjusted.
[0012] By adopting the above technical solution, the penetration ability of dye and fixing agent can be changed by altering the distance between the inkjet printhead and the fabric, thereby adapting to fabrics of different thicknesses and improving the dyeing quality of fabrics of different thicknesses.
[0013] Optionally, the inkjet printhead and the second inkjet printhead use continuous inkjet printing.
[0014] By adopting the above technical solutions, continuous inkjet printing can adapt to different fabric conveying speeds and improve the dyeing quality of the fabric.
[0015] Optionally, both the first inkjet printhead and the second inkjet printhead have multiple printheads arranged in parallel along the direction perpendicular to the fabric conveying direction.
[0016] By adopting the above technical solution, multiple nozzles arranged in parallel along the vertical direction of the fabric conveying direction can simultaneously dye the same position along the length of the fabric, which is beneficial to the consistency of dyeing.
[0017] Optionally, both the first inkjet printhead and the second inkjet printhead have multiple printheads, which are staggered along the fabric transport direction and the projections of the spray ranges of adjacent printheads in the vertical direction of the fabric transport direction overlap on the vertical plane of the fabric transport direction.
[0018] By adopting the above technical solution, the overlapping of the projected portions of adjacent printheads avoids gaps and white streaks in the fabric at the splicing positions between printheads, thus ensuring that the inkjet printhead's spraying range fully covers the fabric in the vertical direction of the fabric transport direction.
[0019] Optionally, both the first inkjet printhead and the second inkjet printhead have multiple printheads, which are staggered along the fabric transport direction and the projections of the spray ranges of adjacent printheads in the vertical direction of the fabric transport direction onto the vertical plane of the fabric transport direction are seamlessly connected.
[0020] By adopting the above technical solution, the projections of adjacent printheads are seamlessly connected, avoiding color differences in the fabric at the splicing position between printheads. This ensures that the inkjet printhead's spraying range fully covers the fabric in the vertical direction of the fabric transport direction.
[0021] Optionally, both the first inkjet printhead and the second inkjet printhead have multiple printheads, each printhead having multiple nozzles arranged along the length of the printhead, the length of the printhead being perpendicular to the fabric conveying direction.
[0022] By adopting the above technical solution, the arrangement of the entire inkjet printhead is facilitated.
[0023] Optionally, both the first inkjet printhead and the second inkjet printhead have multiple printheads, each printhead having multiple nozzles arranged along the length of the printhead, the length of the printhead forming an angle b with the fabric conveying direction, where 0 degrees < b < 90 degrees or 90 degrees < b < 180 degrees.
[0024] By adopting the above technical solution, the number of nozzles is increased, thereby improving the quality of the dyeing process.
[0025] Optionally, the physical resolution of the first inkjet printhead and the second inkjet printhead is 100dpi-600dpi.
[0026] By adopting the above technical solution, the physical resolution of the inkjet printhead can be selected according to the dyeing precision. The physical resolution of 100dpi-600dpi makes the inkjet printhead more adaptable.
[0027] Optionally, both the first and second pad-dyeing components include a pad-dyeing box and a pad-dyeing roller; the pad-dyeing roller includes an upper pressure roller and a lower pressure roller located inside the pad-dyeing box; the fabric passes between the upper pressure roller and the lower pressure roller.
[0028] By adopting the above technical solution, before the fabric leaves the dyeing box, the upper and lower pressure rollers will squeeze out excess dye or curing agent from the fabric, avoiding affecting subsequent processes and the working environment, while reducing the waste of dye or curing agent.

[0046] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.
[0047] 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 dyeing assembly 50, and a second inkjet printhead 30. The fabric conveying mechanism, the first dyeing assembly 50, 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 dyeing assembly 50 and the second inkjet printhead 30 are arranged sequentially along the fabric conveying direction. The first dyeing assembly 50 is used for dyeing the fabric with dye liquor, and the second inkjet printhead 30 is used for spraying a fixing agent. That is, the fabric 10 first undergoes dye liquor dyeing via the first dyeing assembly 50, and then undergoes fixing agent spraying via the second inkjet printhead 30.
[0048] The first pad-dyeing component 50 is a common pad-dyeing device, including a pad-dyeing box and pad-dyeing rollers; the pad-dyeing rollers include an upper pressure roller and a lower pressure roller located inside the pad-dyeing box; the fabric passes between the upper pressure roller and the lower pressure roller. Since inkjet printheads are high-precision devices, their cost is relatively high, while pad-dyeing equipment is relatively simple and has a lower cost; furthermore, using pad-dyeing equipment for dyeing and inkjet printhead for fixing is more water- and energy-efficient and environmentally friendly than using pad-dyeing equipment for both dyeing and fixing.
[0049] The second inkjet printhead 30 has multiple printheads 70, the total spray range of which covers the entire width of the fabric 10. Each printhead has multiple tiny nozzles 71. The physical resolution of the second inkjet printhead 30 is 100 dpi-600 dpi. (Reference) Figure 7 The nozzles 71 of the spray head 70 are arranged along the length of the spray head 70; the length of the spray head 70 is perpendicular to the fabric conveying direction of the fabric 10. In other embodiments, refer to Figure 8 The multiple nozzles 71 of the nozzle 70 are arranged along the length of the nozzle 70; the multiple nozzles 71 of the nozzle 70 are arranged along the length of the nozzle 70; the length of the nozzle 70 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 second inkjet printhead 30 operates on the same principle as existing inkjet printheads, but its ink flow rate can be varied, ranging from 30 to 3000 liters per hour; additionally, the number of nozzles used simultaneously can also be changed. The second inkjet printhead 30 employs continuous inkjet printing, thus adapting to different fabric feed speeds.
[0051] To alter the penetration capability of the second inkjet printhead 30, the distance between the second inkjet printhead 30 and the fabric 10 can be adjusted. This adjustment can be achieved using linear drive components such as electric cylinders or pneumatic cylinders.
[0052] refer to Figure 5 To complete the dyeing or fixing of the entire width of the fabric in one pass, multiple printheads 70 of the second inkjet printhead 30 are arranged in parallel along the vertical direction of the fabric transport direction. The projections of the spraying ranges of adjacent printheads onto the vertical plane of the fabric transport direction are seamlessly connected or partially overlap. When the projections of the spraying ranges of adjacent printheads onto the vertical plane of the fabric transport direction are seamlessly connected, the liquid sprayed by adjacent printheads does not overlap, thus preventing color differences (dark and light streaks) at the seams of adjacent printheads on the fabric 10. When the projections of the spraying ranges of adjacent printheads onto the vertical plane of the fabric transport direction partially overlap, the liquid sprayed by adjacent printheads overlaps, preventing gaps or white streaks at the seams of adjacent printheads on the fabric 10. This ensures that the spraying range of the inkjet printhead fully covers the fabric 10 in the vertical direction of the fabric transport direction, thereby reducing the possibility of missed dyeing. This ONE PASS inkjet dyeing equipment and method greatly improves dyeing efficiency and color consistency before and after dyeing.
[0053] In other embodiments, reference is made to... Figure 6Multiple nozzles 70 are staggered along the fabric 10 conveying direction, and the projections of the spray ranges of adjacent nozzles on the vertical plane of the fabric 10 conveying direction are seamlessly connected or partially overlap.
[0054] Example 2: The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 2 A drying component 40 is set on the support; the drying component 40 is used to dry the fabric 10; the drying component 40 is located between the first pad-dyeing component 50 and the second inkjet printhead 30; the fabric 10 passes through the first pad-dyeing component 50, the drying component 40 and the second inkjet printhead 30 in sequence, that is, after the fabric 10 is pad-dyeed with dye, it is dried and then dyed with a color-fixing agent.
[0055] The drying component 40 is existing technology and generally includes a drying chamber and a drying element. The drying element is set inside the drying chamber and uses electric heating, gas heating, lamp heating or steam heating. In order to make the drying uniform, the drying chamber is generally also equipped with a hot air circulation element to make the heat uniform.
[0056] Example 3: The difference between Example 3 and Example 1 is as follows: (Refer to...) Figure 3 A second pad-dyeing assembly 60 replaces the first pad-dyeing assembly 50 as the pad-dyeing assembly, and the second pad-dyeing assembly 60 is used for pad-dyeing with a color-fixing agent on the fabric; a first inkjet printhead 20 replaces the second inkjet printhead 30 as the spraying assembly, and the first inkjet printhead 20 is used to spray dye onto the fabric 10; that is, the fabric 10 first undergoes color-fixing agent pad-dyeing through the second pad-dyeing assembly 60, and then undergoes dye spraying through the first inkjet printhead 20. The structure of the second pad-dyeing assembly 60 is the same as that of the first pad-dyeing assembly 50; the structure of the first inkjet printhead 20 is the same as that of the second inkjet printhead 30.
[0057] Example 4: The difference between Example 4 and Example 3 is as follows: (Refer to...) Figure 4 A drying component 40 is set on the support; the drying component 40 is used to dry the fabric 10; the drying component 40 is located between the second pad-dyeing component 60 and the first inkjet printhead 20; the fabric 10 passes through the second pad-dyeing component 60, the drying component 40 and the first inkjet printhead 20 in sequence, that is, after the fabric 10 is pad-dyeed with a color-fixing agent, it is dried and then dyed with dye liquor.
[0058] The drying component 40 is existing technology and generally includes a drying chamber and a drying element. The drying element is set inside the drying chamber and uses electric heating, gas heating, lamp heating or steam heating. In order to make the drying uniform, the drying chamber is generally also equipped with a hot air circulation element to make the heat uniform.
[0059] All the above embodiments are applied to color-fixing agents, but they can also be applied to other additives, such as synergists, waterproofing agents, antibacterial agents, sunscreens, and fire retardants.
[0060] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
