Description

[0001] The publication in question refers to the technical field of equipment for dyeing fabrics, and in particular to a digital dyeing machine with an inkjet printer for dyeing fabrics in pure colors.

STATE OF THE ART

[0002] With the continuous improvement of people's quality of life and the continuous improvement of modern technology, people have an increasing demand for the color of fabrics. For dyeing different types of fabrics in pure colors, traditional dyeing process can be used and digital printer can be used to print individual colors. Document US 2020/316945 A1 discloses such a digital inkjet dyeing machine.

[0003] Traditional fabric dyeing processes can be classified into dip dyeing and "drop" dyeing according to the different ways of contact between the dye and the fabric. Dip dyeing is a dyeing process in which the fabric to be dyed is immersed in a dye solution, and the dye is evenly applied to the textile by circulating the dye solution and relative movement of the fabric to be dyed, whereby when dip dyeing is performed, the dye and the fabric can be circulated simultaneously or individually. "Drop" dyeing is carried out by immersing the open width fabric in the dye solution for a short time, then the dye solution is squeezed into the interior of the fibers and voids of the fabric through a pressure roller and removes the excess dye solution, so that the dye is evenly distributed on the fabric, and the fabric, after being underlaid and coated with dye, is steamed or baked to complete the diffusion and fixation of the dye on the fiber. However, the traditional dyeing process has the following disadvantages: large minimum order quantity, large differences in color matching, large water consumption, large amount of steam, large differences between color matching and dyeing matching, and greater reliance on the skills of dyeing personnel; consequently, the traditional dyeing process is not environmentally friendly, expensive, and of low efficiency. The traditional dyeing process has the following advantages: a wide range of colors, good color uniformity, and a high level of depth and shade.

[0004] However, all pure color printing achieved by digital printing in the current market is based on the printing mode of the digital printing machine, where different colors are applied to dots using the dot positioning mode to achieve a pure color effect. This printing process has a problem in that the printed fabric in pure color is visually grainy, resulting in coarse dots, insufficient ink hue and saturation, insufficient color depth and quantity, and unsatisfactory color consistency. Accordingly, the digital printing machine has the disadvantage of not being able to achieve industrialization, large block area, high speed, and long-term pure color printing. In addition, the digital printing machine has high requirements for color management when printing, however, the degree of color restoration cannot meet the requirements of pure color printing, and the range of colors that can be printed is limited.

[0005] Considering that, how to overcome the disadvantage that the traditional dyeing process is not environmentally friendly, has high costs and low efficiency, and digital printing in pure color is dot-grained and has low color accuracy, when dyeing in pure color, becomes a topic that should be investigated and solved by the publication in question.

[0009] The relevant content of the publication in question is explained as follows:

1. The working procedure of the above-mentioned technical solution is as follows: performing a fixed single-channel dyeing production with an inkjet printer, and placing the pre-treated fabric for dyeing on the machine; filling the paint system with paint; starting the machine, transporting the fabric to be dyed to the inkjet device station using the unwinding and feeding device, directly spraying and dyeing the dye using the inkjet device and inkjet printing the prepared dye on the fabric; transporting the printed fabric to the drying device by means of a belt guide device; and winding the dried fabric using a winder. Nodes are added for newly added colors, so the accuracy of the formula with later added colors is greatly improved. Only one group of inkjet modules is working while the dyeing operation is in progress. When the first group of inkjet modules is working, the other inkjet modules perform cleaning and ink replacement under the control of the microcomputer, whereby first, the ink in the other inkjet modules is emptied, then the valves of the pool with the cleaning liquid that is in communication with the other inkjet modules are opened for cleaning, after the cleaning is completed, the valves of the pool with the prepared ink are opened and the ink enters the other inkjet modules in preparation for printing the next color.

2. In the above technical solution, the inkjet printing device includes two groups of inkjet printing modules, the spray head groups in the two groups of inkjet printing modules are each connected to one of the ink tanks, and the spray head groups in the two groups of inkjet printing modules are jointly connected to the cleaning liquid tank and the waste liquid bin; however, the subject disclosure is not limited thereto, and one ink module may use a cleaning fluid tank and a waste fluid bin separately.

3.

4. In the above technical solution, the upper surface of the cleaning liquid flow guide plate is formed with a trapezoidal flow guide groove, and the flow guide hole is placed at the bottom of the flow guide groove. The trapezoidal flow guide groove is designed as a trapezoidal groove, so that the cleaning ink or waste ink can easily flow out of the flow guide groove and pour into the waste liquid bucket through the flow guide hole, which accelerates the cleaning efficiency and facilitates the cleaning and ink change (color change) work.

5. In the above technical solution, the machine body is divided into two parts, the inkjet printing module, ink tank, working surface and cleaning surface are independently arranged in each machine body, and the two machine bodies share the cleaning liquid tank and the waste liquid bin. The purpose of independently arranging the inkjet printing module, ink tank, working surface, and cleaning surface in each of the machine body is to facilitate the completion of inkjet printing of the spray head group, and the inkjet printing and cleaning work in each machine body is not interrupted when cleaning and ink change (color change) is required, and the cleaning and ink change work can be carried out independently, so that the cleaning and ink change (color change) is more thorough and avoids staining.

6. In the above technical solution, the lower part of the machine body is equipped with a universal wheel, so that the machine body can be easily moved, and subsequent repairs, maintenance or other operations can be easily done.

In the above technical solution, the spray head has an ink amount of 12 pl to 80 pl, the ink used is compatible with the ink used by the digital printing machine, and the special ink for the digital dyeing machine can be used, which has a large particle size range, less damage to the chromogenic groups, and a greatly improved color development effect than pure color printing by the printing machine.

8. In the above technical solution, the spray heads in the inkjet printing module are connected by a pipeline in a single-channel serial connection mode, that is, the ink pipelines between the spray heads are connected in series, and the ink is sprayed and printed on the surface of the fabric by a series of fixed spray heads in one channel, so that the most unpleasant feeling of dot grain shape that occurs in the conventional digital printing machine will not appear.

9. In the above technical solution, the digital inkjet dyeing machine is further equipped with a belt guiding device, wherein the belt guiding device is placed between the inkjet device and the drying device and is configured to transfer the fabric dyed by the inkjet device to the drying device.

10. In this publication, unless otherwise clearly stated and defined, the terms "installation", "connection", "connection", "fixation" and the like should be understood in a broad sense. For example, unless otherwise clearly limited, the term "joint" may be a fixed joint, a detachable joint, or an integration; it can be a mechanical connection or a direct connection, it can be an indirect connection implemented using an intermediary, or it can be a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meanings of the above terms in the subject disclosure according to specific cases.

11. In the subject disclosure, assembly orientation or location relationships denoted by the terms "center," "above," "below," "circular," "bottom," "inner," "outer," and the like are orientation or location relationships based on the accompanying drawings and are intended only to facilitate the description of the subject disclosure and to simplify the description, and not to indicate or imply that the subject apparatus or element should have a particular orientation or should be constructed and works in a certain orientation.

[0010] By applying the above solution, compared to conventional technology, the subject publication has the following advantages and effects:

1. According to the above solution of the subject publication, the fixed single-channel spray heads are used to evenly apply the ink according to the color of one color on the textile to complete the pure color digital printing. In this way, the most problematic sense of dotty graininess that occurs with a conventional digital printing press will be avoided. A spray head with a large amount of ink can be used due to the condition that there is no feeling of dot grain shape, and the ink used can be compatible with the ink used by the digital printing machine, meanwhile, the special ink for digital dyeing machines can also be used, and such ink has a large particle size range, less damage to chromogenic groups, and a greatly improved color development effect than pure color printing by the printing machine.

2. According to the above solution of the subject announcement, at least two groups of inkjet modules are used, and two groups of inkjet modules can be used alternatively, where one group of inkjet modules enters the inkjet printing position in the working area under the influence of the lifting unit of the support and movement mechanism and descends to a certain height to perform inkjet printing, and the other group of inkjet modules can perform cleaning or ink replacement in the cleaning area; when the inkjet modules in the working area finish inkjet printing and need to be cleaned or replaced with ink, after the lifting unit of the support and moving mechanism drives the inkjet module to a certain height, the moving unit drives the inkjet module to move horizontally into the cleaning area, that is, to move above the cleaning fluid flow guide plate for cleaning and ink replacement, and another group of inkjet modules enters the working area for inkjet printing; therefore, the work efficiency is high, and the spray heads are cleaned in time to prevent clogging of the spray heads and prevent the remaining ink from affecting the quality of inkjet printing.

3. According to the above solution of the subject publication, the spray heads are arranged on the positioning frame in rows, and the inkjet printing modules are driven by the lifting unit of the carrying and moving mechanism to be lowered into the inkjet printing position in the working area during inkjet printing, and then the inkjet printing operation is performed, so that the accuracy of inkjet printing is high and the effect of inkjet printing is good.

4. According to the above solution of the subject publication, the inkjet printing module can print dispersed, active, coated, acid and other inks, and the printing fabrics include almost all kinds of fabrics such as polyester, cotton, silk, wool, blended fabrics; therefore, the scope of application is wide.
