Description
Technical Field
The invention relates to the technical field of digital jet printing, in particular to a digital jet printing system and a digital jet printing method.
Background
Along with the improvement of living standard of people, people have higher and higher requirements on the color quality of cloth or other printed matters. When printing on cloth or other printed matters, the phenomena of color particles, uneven color and the like generated in the jet printing process are inevitable in both the traditional printing mode and the digital jet printing technology which is popular in recent years. This phenomenon is not significantly affected when spray printing a cloth that is completely a fancy color without a large area of ground color, because human eyes are not sensitive to color particles, color unevenness, and the like in a gradation color or a complex pattern. However, since human eyes are particularly sensitive to color particles and color unevenness on a pure color pattern, when a cloth with a ground color (such as the pattern shown in fig. 1) is sprayed, problems such as color particles and unevenness appear particularly conspicuous in the ground color portion, resulting in poor printing quality.
In the existing jet printing technology, the pure color pattern is usually formed by ejecting ink from a plurality of basic color nozzles according to a certain proportion and mixing the ink to form a target color. However, in this method, since the nozzle can only spray-print a narrow strip-shaped area at a time, when the next strip-shaped area is sprayed, it is necessary to make the next strip-shaped area perfectly engage with the previous strip-shaped area, and no gap occurs. However, this solution requires the feathering of a plurality of colors to be controlled simultaneously, which is very difficult, and thus it is difficult to control the accuracy and uniformity of the colors.
In addition, in the scheme, when any spray hole of any spray head has a problem, very obvious color flaws are generated, and if the color flaws cannot be found in time, the whole piece of cloth can be scrapped. Even if the fault can be timely found and eliminated, the color sprayed after the fault is eliminated is difficult to be completely consistent with the color sprayed before and difficult to be perfectly connected with the part which is sprayed and printed before, and the whole piece of cloth can be scrapped. Due to the large number of jets (e.g., four, six, eight, etc.) in this arrangement, the probability of the above-described problems occurring is very high.

Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
As shown in fig. 1, an embodiment of the digital jet printing system of the present invention includes a feeding device for feeding out a medium 10, a receiving device for receiving the medium 10, and at least one set of jet printing devices 3 disposed between the feeding device and the receiving device, where each set of jet printing devices includes a first nozzle 31 for jet printing a pure color and a second nozzle 32 for jet printing a pattern. The medium referred to in the present invention is especially cloth, but of course other media are possible, and the printing medium may be either a whole roll or a single sheet.
As shown in fig. 2 and 3, in the present embodiment, the first head 31 is provided on a beam 33 arranged in a direction perpendicular to the traveling direction of the medium 10, and the first head 31 covers a width of the jet print equal to or larger than the width of the medium 10. Also, the second head 32 is provided on a beam arranged in a direction perpendicular to the traveling direction of the medium 10, and the second head 32 covers a width of the jet print equal to or larger than the width of the medium 10. In this embodiment, the first nozzle 31 and the second nozzle 32 may share the same beam 33, or may be disposed on different beams.
As shown in fig. 4, in this embodiment, the first spray head 31 and the second spray head 32 are both disposed on a spray head carriage 34 that can reciprocate in a direction perpendicular to the traveling direction of the medium 10, and the spray head carriage 34 is supported by a slide rail 35 to reciprocate. The first spray head and the second spray head are preferably in the same horizontal position on the spray head trolley.
According to the invention, two spray heads are configured, wherein the first spray head 31 is specially used for spray printing pure color and is easy to control, the spray printed pure color part can not generate color particles and uneven phenomena, and the second spray head 32 is used for spray printing patterns, so that rich color spray printing is realized, and the overall printing quality is greatly improved. The invention reduces the number of the spray heads used for spray printing pure color parts, thereby greatly reducing the failure rate, and because all the spray holes of the first spray head 31 are responsible for spray printing the same color, even if the spray head or the spray hole has failure, the influence is not obvious, and the invention can be corrected by increasing the ink jet amount of other spray heads or spray holes.
Specifically, taking as an example the pattern shown in fig. 5, which includes a solid color portion 51 (which may be referred to as ground color) and a design pattern portion 52, is inkjet printed on the medium 10. When the jet printing system of the invention is used for jet printing, firstly, the pattern to be jet printed is decomposed into a ground color pattern (shown in fig. 6) and a pattern (shown in fig. 7), then the ground color pattern data is transmitted to the first nozzle 31, and the first nozzle 31 finishes the jet printing of the ground color part; at the same time, the pattern data is transmitted to the second nozzle 32, and the second nozzle 32 performs the jet printing of the pattern portion. Although the pure color part and the pattern part are separately sprayed and printed in the mode, the pure color part and the pattern part can be simultaneously sprayed and printed, so that the spraying and printing of all patterns can be finished by one-time material feeding, and the spraying and printing efficiency cannot be reduced. And because the pure color part is sprayed and printed by the independent spray heads, the color allocation, the ink spraying amount and the ink spraying uniformity of the ink are easier to control during the spraying and printing, so that the color of the sprayed and printed ground color is accurate and uniform, color particles cannot be generated, and the spraying and printing quality is greatly improved.
In the embodiment shown in fig. 2 and 3, the first spray head 31 and the second spray head 32 are both arranged on the beam, and the spray heads cover a spray width equal to or greater than the width of the medium 10. In this way, the entire width of the medium 10 can be printed in one operation, and only the movement of the medium 10 needs to be controlled during the printing operation, but the spray head does not need to be moved. On one hand, the spray printing efficiency is greatly improved; on the other hand, the structure of the jet printing device is greatly simplified, the cost is reduced, and the failure rate is reduced; on the other hand, the control system is simpler, the cost is further reduced, and the method is favorable for the consistency and uniformity of jet printing colors.
In the embodiment shown in fig. 4, the first spray head 31 and the second spray head 32 are disposed on a spray head carriage 34, and the spray head carriage 34 can reciprocate on a slide rail 35 to spray print the entire width of the medium 10. And the jet printing of the pure color part and the pattern part can be finished by one-time scanning jet printing (namely, the jet head trolley moves from one end to the other end and finishes the jet printing in the moving process). The advantage of this embodiment is that the second shower nozzle mechanism of spouting seal decorative pattern can adopt ripe prior art to realize, can reduce experimental test cost.
The first nozzle 31 may be supplied with ink by an ink supply device (not shown). In one embodiment, the ink supply device includes ink tanks for containing the prepared ink, the ink tanks being connected to the first heads through pipes, respectively. According to the embodiment, before the jet printing operation, the ink is prepared according to the required jet printing color and the required amount, and then the prepared ink is injected into the ink storage box. During jet printing operation, ink in the ink storage tank is supplied to the first nozzle through the pipeline, and jet printing operation is completed.
In another embodiment, the ink supply device includes an ink mixing tank and a plurality of ink cartridges, the plurality of ink cartridges being respectively for containing a plurality of inks of different colors, the ink mixing tank being respectively connected to the first head through a pipe, the ink mixing tank being respectively connected to the plurality of ink cartridges through a pipe. Based on the embodiment, ink does not need to be prepared before jet printing operation, and only the proportion of each basic color ink needs to be calculated according to the color required to be jet printed, and the ink of each color is supplied to the ink mixing box through the pipeline. During operation, ink is proportionally drawn from the ink boxes with the basic colors, is mixed in the ink mixing box in real time, and then is supplied to the first spray head through the pipeline, so that the spray printing operation is completed. In this embodiment, the ink usage of each basic color may be provided as needed according to the calculated mixture ratio and usage, or may be provided in excess when the usage is satisfied, for example, the usage may be provided in an amount of one color with the largest usage or more. Because the embodiment is mixed in real time in the operation process, the amount of the ink is used, the ink with the basic color cannot be polluted, and more ink is provided without waste.
Similarly, the second nozzle needs to print a pattern, so the ink supply device comprises an ink mixing box and a plurality of ink boxes, wherein the plurality of ink boxes are respectively used for containing a plurality of inks with different colors, the ink mixing box is respectively connected to the first nozzle through a pipeline, and the ink mixing box is respectively connected to the plurality of ink boxes through a pipeline. The ink supply device draws ink from the ink boxes with the basic colors in real time in proportion according to the colors to be sprayed and printed, mixes the ink in the ink mixing box in real time, and then supplies the ink to the second spray head through a pipeline to finish the spraying and printing operation.
In other embodiments, the second nozzles may be divided into a plurality of groups, each of the nozzles in each group of second nozzles is supplied with ink from an ink cartridge of a different color, and the amounts of ink ejected from each of the nozzles in each group of second nozzles are controlled according to the color to be printed, so that the inks are mixed on the printing medium in proportion to obtain the color to be printed.
In an embodiment of the present invention, the feeding device is located above the receiving device, so that the medium 10 travels from top to bottom in a vertical direction, and two sets of the inkjet printing devices 3 are located on two sides of the medium 10 respectively. The structure can simultaneously spray and print two surfaces of the medium from two sides of the medium 10, and greatly improves the spray printing efficiency. The medium 10 is made to advance from top to bottom in the vertical direction, on one hand, the spray head is made to spray and print the medium from two sides in the horizontal direction, so that the spray printing is more uniform, and the medium 10 does not need to be reversed; on the other hand, the tension of the medium 10 is easier to control, and the phenomenon of uneven jet printing caused by the tension change of the medium 10 is avoided.
In other embodiments, the medium may travel in a horizontal direction, and the first and second heads eject ink droplets toward the medium in a vertical direction. In the implementation, if double-sided jet printing is required, two groups of jet printing devices can be respectively arranged on the upper side and the lower side of the medium, and the medium is subjected to jet printing from top to bottom and from bottom to top; the first group of spray printing devices can be arranged on the upper side of the medium, the first surface of the medium is sprayed and printed from top to bottom, then the advancing direction of the medium is rotated by 180 degrees through the steering wheel, the second group of spray printing devices are arranged on the upper side of the steered medium, and the second surface of the medium is sprayed and printed from top to bottom.
Because most of media, especially cloth, are woven by fibers, ink drops ejected by the nozzles inevitably pass through gaps among the fibers and enter air, if the ink drops are not processed, the opposite nozzles are easily polluted by the ink drops, and the air is polluted by the ink drops flying into the air, so that the health of operators is influenced after the ink drops are inhaled by the operators. In addition, ink droplets ejected from the ejection head are influenced by air resistance or are rebounded by the medium after contacting the medium, and a part of the ink droplets can also be diffused into the air.
Therefore, as shown in fig. 2, in the present embodiment, two sets of the inkjet printing devices 3 are staggered in the vertical direction, and a recovery device 11 is disposed on the other side of the medium 10 corresponding to each set of the inkjet printing devices 3. Wherein the recycling device 11 comprises a negative pressure cavity, and the negative pressure cavity is communicated with a negative pressure source (for example, a vacuum pump can be adopted, and is not shown in the figure); and a suction port is formed in one side of the negative pressure cavity facing the jet printing device 3. Negative pressure is generated in the negative pressure cavity through the negative pressure source, surrounding air is sucked into the negative pressure cavity through the suction port, ink droplets in the air are simultaneously sucked into the negative pressure cavity and then discharged into the atmosphere after being filtered, and air pollution caused by the ink droplets is avoided.

In this embodiment, the medium can vertically pass through the inkjet printing operation position only by disposing the feed roller mechanism in the feed device above the inkjet printing device and disposing the receiving roller below the inkjet printing device. The material feeding roll 8, the centering device 7, the heating device 6, the floating roll mechanism 5, the feeding roll mechanism 4, the material receiving roll 9 and the material receiving roll 1 can adopt the structures existing in the prior art.
