Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printing, in particular to a UV ink matte curing printing device and printing equipment. Background Art

[0002] With the booming personalized printing market and the growing demand for differentiated product design, the market's pursuit of special printing effects has become increasingly urgent, especially for a mixed presentation of glossy and matte effects.

[0003] In order to achieve glossy and matte printing effects, the existing technology uses a separate varnishing machine after the printing process to apply glossy varnish or matte varnish using a rubber roller coating technology. Although the required gloss effects can be achieved respectively, the curing process relies on high-temperature heating (140-180°C), which not only consumes a lot of energy, but also can only achieve a single gloss coverage of the entire page. It is impossible to simultaneously display a mixed effect of glossy and matte on the same printed page, which limits the design flexibility and innovation space.

[0004] Another prior art, such as the "Partial UV Printing Process for Metallic Ink Surfaces" described in Patent No. 200910052856.2, successfully achieves a contrasting effect between glossy and matte finishes in localized areas. However, its technical approach is limited to screen printing and imposes strict requirements on substrate materials (preferring non-metallic materials), raw materials (limited to UV coatings and metallic inks), and resin types, limiting its applicability. Furthermore, the process is complex, requiring specific low-temperature reactions, multiple coatings, and varying drying methods, increasing production costs and operational complexity. Furthermore, the order of glossy and matte finishes is fixed, lacking reversibility and limiting processing flexibility.

[0005] In summary, current technologies for achieving both glossy and matte print effects often face challenges, including complex processes, increased material costs, high equipment investment, and cumbersome operation and maintenance. In particular, it's difficult to flexibly and efficiently combine glossy and matte effects on the same page within a single print run, limiting the full realization of personalized and diverse designs. Therefore, developing a technical solution that simplifies the process, reduces equipment and material costs, and allows for the flexible combination of glossy and matte effects within the same print run has become a key challenge urgently needed in the industry.

If there is no conflict, the various features of the embodiments and examples of the present invention may be combined with each other and are all within the scope of protection of the present invention.

[0045] Example 1

[0046] See Figure 1 , an embodiment of the present invention provides a UV ink matte curing printing device, the device comprising: a spray car assembly 1, a first UV module 2 and a second UV module 3;

[0047] In the scanning direction of the spray carriage assembly 1, the first UV module 2 and the second UV module 3 are arranged side by side at one end of the spray carriage assembly 1, and in the direction in which the spray carriage assembly 1 moves relative to the substrate, the first UV module 2 is in front of the second UV module 3;

[0048] The second UV module 3 is used to cure the ink to form a glossy effect, and the first UV module 2 is used to cure the ink to form a matte effect.

[0049] Specifically, the inkjet carriage assembly 1 is used to be installed on a crossbeam of a printing device, and performs scanning movement on the crossbeam to perform inkjet printing on a substrate.

[0050] In inkjet printing, Figure 2As shown, the spray car assembly 1 reciprocates on the beam. Generally, the scanning direction of the spray car assembly 1 is moving on the beam. Figure 2 The first direction shown is moved and ink is sprayed for scanning and covering printing. The first UV module 2 and the second UV module 3 are installed at the rear end of the spray car assembly 1 in the first direction. The second direction is the way in which the spray car assembly 1 moves relative to the printing material. In the second direction, the first UV module 2 is set in the front and the second UV module 3 is set in the back.

[0051] In the direction of relative movement of the inkjet carriage assembly 1 relative to the printing substrate, the first UV module 2 is in front of the second UV module 3, so that when the printing substrate and the inkjet carriage assembly 1 move relative to each other, the uninked printing substrate moves below the first UV module 2, and after the inkjet is completed, the inkjet carriage assembly 1 and the printing substrate move relative to each other, and the inkjet-finished printing substrate moves below the second UV module 3.

[0052] When a matte effect is required, the inkjet carriage assembly 1 moves in the first direction to spray ink onto the substrate. The front of the nozzle on the inkjet carriage assembly 1 sprays ink onto the substrate. During the movement, the first UV module 2 moves to the substrate where the ink has just been sprayed to solidify the ink. That is, the first UV module 2 solidifies the ink once for each pass of inkjet printing. That is, the time between the ink spraying and the ink being solidified by the first UV module 2 is very short, so that the ink is quickly cured by the first UV module 2 to form a matte effect. Figure 2 As shown, when a matte effect is required, the nozzle cures the first area below the first module. Each time the nozzle sprays ink to scan and print the first area, the first UV module 2 cures the first area.

[0053] like Figure 2As shown, when a glossy effect is required, the inkjet carriage assembly 1 moves in steps relative to the printing platform in the second direction. In one-pass printing, the inkjet carriage assembly 1 sprays ink on the first area to perform a scanning print. The inkjet carriage assembly 1 and the printing platform move relative to each other in the second direction. Before the movement, the position of the substrate in the first area moves to the second area. The substrate that has completed inkjet printing is moved under the second UV module 3 for light curing. In multi-pass printing, each time a pass is completed, the inkjet carriage assembly 1 and the printing platform move in steps relative to each other in the second direction. When the substrate carrying ink moves to the second area, the multi-pass inkjet printing is completed. There is a certain time difference between the ink being sprayed onto the substrate and the ink being irradiated by the second UV module 3. The ink has sufficient time to level, and the ink layer cured by the second UV module 3 is thicker. Curing by the second UV module 3 makes the ink present a glossy effect.

[0054] In one embodiment, if Figure 3 、 Figure 4 As shown, the spray carriage assembly 1 includes a carriage unit 11 and a spray head unit 12;

[0055] The nozzle unit 12 is installed below the carriage unit 11 and is used to spray ink onto the substrate on the printing platform;

[0056] The first UV module 2 is fixed to one end of the trolley unit 11 through a first mounting plate 13 .

[0057] Specifically, a pair of first baffles 111 and second baffles 112 are arranged to extend relatively below the trolley unit 11 , and the nozzle unit 12 is placed on the first baffles 111 and the second baffles 112 , that is, the nozzle unit 12 is arranged in the trolley unit 11 .

[0058] At the same time, the trolley unit 11 is respectively provided with a group of fixed plates on both sides of the first baffle 111 and the second baffle 112, and the group of fixed plates includes a first fixed plate 113 and a second fixed plate 114. The nozzle unit 12 is fixedly connected to the trolley unit 11 and the nozzle unit 12 by a fixing part passing through the first fixed plate 113 and the second fixed plate 114 to prevent the nozzle unit 12 from shaking during movement and affecting the nozzle unit 12 from spraying ink.

[0059] The first mounting plate 13 is longer than the nozzle unit 12 in the direction of relative movement between the carriage assembly 1 and the printing substrate. The first UV module 2 is installed at one end of the first mounting plate 13 that is aligned with the nozzle unit 12, and the second UV module 3 is installed at the other end that is not aligned with the nozzle unit 12.

[0060] In one embodiment, if Figure 5 、 Figure 6 As shown, the trolley unit 11 includes a fixed support frame 115 and a movable fixed frame 116;

[0061] The movable fixing frame 116 is installed on the beam and is used to drive the inkjet carriage assembly to reciprocate on the beam to spray ink on the substrate. The fixed support frame 115 is installed on one side of the beam and is fixedly connected to the movable fixing frame 116.

[0062] Specifically, the nozzle unit 12 is arranged at the bottom of the fixed support frame 115, and the first UV module 2 and the second UV module 3 are arranged at one side end of the support frame. The fixed support frame is used to provide support for the nozzle unit 12 and the first UV module 2 and the second UV module 3; a second mounting plate 14 is provided between the fixed support frame 115 and the movable fixed frame 116, and the fixed support frame 115 is fixedly mounted on the second mounting plate 14 through a fixing part.

[0063] A sliding connector 141 is provided on one side of the second mounting plate 14 close to the crossbeam. The sliding connector 141 is connected and paired with the sliding guide rail 41 at the side end of the crossbeam. When the spray truck assembly 1 moves on the crossbeam, the sliding connector 141 slides on the sliding guide rail 41.

[0064] The movable fixing frame 116 includes a sliding base plate 1161, and the clavicle sliding base plate 1161 is bent and extended downward near one end of the fixed support frame 115 to form a bending portion 1162. The second mounting plate 14 is fixedly connected to the bending portion 1162 through a fixing member (not shown in the figure).

[0065] In one embodiment, if Figure 5-7 As shown, the first UV module 2 / the second UV module 3 includes a UV light source (not shown in the figure) and a module frame 5. The UV light source is placed in the module frame 5, and the module frame 5 is provided with a window 52 on the side facing the substrate, for the light of the UV light source to pass through and illuminate the substrate;

[0066] The module frame 5 is provided with a heat dissipation window 51 for allowing air circulation to dissipate the heat generated by the UV light source into the air.

[0067] Specifically, the module frame 5 is used to connect with the first mounting plate 13 to provide a supporting mounting structure for the UV light source. At the same time, the UV light source is built into the module frame 5, so that the light of the UV light source can be irradiated from the window 52 to the substrate directly below, making the UV light irradiation more concentrated and uniform, effectively improving the curing speed and curing quality, and is particularly suitable for printing, coating curing and other fields that require high precision and fast response.

[0068] At the same time, the heat dissipation window 51 is provided to effectively control the operating temperature of the UV module, reduce the impact of thermal stress on the light source and surrounding electronic components, extend the service life of the entire system, and reduce maintenance costs.

[0069] In one embodiment, the device includes a plurality of the first UV modules 2, and the number of the first UV modules 2 is set according to the printing width of the print head during one scan;

[0070] The number of the second UV modules 3 is set according to the stepping distance of the relative movement between the nozzle and the substrate.

[0071] Specifically, the printing width of the print head during one scan is the width data of the traces formed on the substrate by the ink discharge from all nozzles when the print head on the print head unit 12 moves on the crossbeam in the direction of relative stepping between the carriage assembly and the substrate.

[0072] The number of the first UV modules 2 is set according to the printing width, so that the ink can be fixed in time to form a matte effect when the inkjet printing vehicle assembly 1 performs inkjet printing.

[0073] By setting the number of second UV modules 3 according to the stepping distance, the second UV module 3 can solidify the ink that moves and steps to the bottom of the second UV module 3 after completing inkjet printing, thereby avoiding the situation where the number of second modules is insufficient, resulting in part of the ink not being able to be irradiated and fixed, affecting the printing effect.

[0074] In another embodiment, the first UV module 2 is a first UV lamp with independent switch control, and the second UV module 3 is a second UV lamp with independent switch control.

[0075] Specifically, each UV lamp is installed independently, with a simple structure and easy installation and replacement; the independent control of each UV lamp achieves high flexibility, and the working status of each lamp can be adjusted individually according to needs, with low maintenance costs.

[0076] In another embodiment, Figure 8 Said first UV module 2 and said second UV module 3 include a light bar 7, said light bar 7 specifically including a plurality of independently controlled UV lamp beads 71;

[0077] The UV lamp beads 71 on the light bar 7 are used to be divided into bright lamp beads and matte lamp beads according to the direction of relative movement between the spray car assembly 1 and the substrate;

[0078] The bright lamp beads are used to solidify the ink on the substrate to form a bright effect, and the matte lamp beads are used to solidify the ink on the substrate to form a matte effect.

[0079] Specifically, the UV module also includes an electronic control unit and a light guide plate. The electronic control unit is used to control the on / off switching of the lamp beads 71 on the light bar 7. The UV light source's light beam passes through the light guide plate and illuminates the ink on the substrate surface, ensuring that the UV light is evenly irradiated on the ink, improving print quality. Through the electronic control unit's independent control of the lamp beads 71 on the light bar 7, matte and glossy lamp beads can be divided according to the print width and step distance of the print head unit 12, better matching printing needs and achieving a more flexible combination of matte and glossy printing effects.

[0080] At the same time, the multiple closely arranged lamp beads 71 on the light bar 7 help to achieve more uniform lighting, improve printing quality, and achieve more precise lighting effect adjustment.

[0081] In one embodiment, when reciprocating scanning printing is required, the device includes two groups of UV modules, each group includes at least one first UV module 2 and the second UV module 3, and the two groups of UV modules are respectively arranged at the two side ends of the spray car assembly 1.

[0082] Specifically, a group of UV modules are provided at both ends of the spray carriage assembly 1 to achieve the purpose of curing the ink while spraying the ink in both the reciprocating and the back-and-forth processes.

[0083] At the same time, it can also ensure the curing effect when the same ink is cured multiple times.
