Description

Technical Field

[0001] The invention relates to the technical field of printing and embossing, and more specifically, to an ultraviolet curing embossing device based on screen printing. Background Art

[0002] The screen printing UV curing device is a printing tool used to scrape ink and cure the printed object by UV light, thereby helping technicians to print on various paper and ceramic printed objects, and at the same time compare and evaluate the printed object effect with the standard effect, and then package the printed objects that meet the evaluation quality standards and ship them out for customers to buy and sell.

[0003] Most of the existing screen printing UV curing devices are fixed one-way printing devices, which can only print on the paper printing surface within a fixed range during the printing process. Not only is the printing area small and the efficiency low, but also because the light-emitting lamp used for UV curing and the printing head used for printing do not work synchronously, the printing ink on the paper printing surface will be blurred and have ghost images during the printing process.

[0004] In response to the above technical problems, the prior art has proposed some solutions. For example, a Chinese patent with authorization announcement number CN216817168U discloses a UV-curing embossing device based on screen printing. The driving assembly and light-emitting component provided in the device can drive the carrier plate and the light-emitting component to perform lateral relative movement, so that the light-emitting component and the carrier plate can simultaneously print and UV-cure the paper substrate, thereby improving the embossing efficiency and increasing the effect of large-area graphic embossing.

[0005] However, in the actual printing and curing process of the existing screen printing UV curing device, this printing method can only perform ink printing operations on the paper printing surface within the sliding range. The printing head cannot print in place for the larger paper bite corners clamped by the printing screen, resulting in problems such as uneven colors, uneven paper surfaces, too light ink prints, and blurred handwriting on the printed surface of the paper after printing, resulting in low usability of the paper after printing, reducing printing efficiency, and affecting the normal UV curing.

[0044] The bottom of the polygonal fixed plate 22 is fixedly connected with a concave limit plate 23, and two concave limit plates 23 are provided, and the two concave limit plates 23 are symmetrically distributed and contact with both sides of the double-head cylinder 2 24, and the bottom notch of the concave limit plate 23 is slidably engaged with the outer surfaces of the slider 1 25 and the slider 2 26, and the top surface of the movable plate 218 is fixedly connected with a hollow box 28.

[0045] The inner top wall of the telescopic box 211 is fixedly connected with a spring 215, the bottom of the spring 215 is fixedly connected with a scraper 212, the top of the conveying unit 11 is movably connected with a printing screen 12, the cut end of the scraper 212 is in contact with the inner mesh surface of the printing screen 12, the outer surface of the printing screen 12 is clamped with a telescopic support plate 219, and the top of the telescopic support plate 219 is fixedly connected to the polygonal fixing plate 22.

[0046] The scraper 212 has a blade 213 slidably inserted on the front side, a spring 216 is fixedly connected to the rear side of the blade 213, and the rear side of the spring 216 is fixedly connected to the inner wall of the scraper 212. The scraper 212 has a blade 214 slidably inserted on the rear side, a spring 3 217 is fixedly connected to the front side of the blade 214, and the front end of the spring 3 217 is fixedly connected to the inner wall of the scraper 212.

[0047] In view of the prior art, the screen printing UV curing device can only perform ink printing operations on the paper substrate within the sliding range during the actual imprinting and curing process. For the larger paper bite corners clamped by the printing screen 12, the scraper 212 cannot print in place, resulting in the problem that the printed surface of the paper has different colors, uneven paper surface, too shallow ink prints, and blurred handwriting after printing. The present application sets a lifting and translation assembly 2. When in use, the pre-printed printing screen 12 is first fixed between the bottoms of the four telescopic support plates 219, and then the transmission unit 11 is powered on to transmit the pre-printed paper substrate to the bottom of the printing screen 12.

[0048] Then, ventilation drives the output end of cylinder 1 21 to contract downward, driving the fixedly connected polygonal fixing plate 22 to move downward, so that the polygonal fixing plate 22 drives the telescopic support plate 219 and the concave limit plate 23, the double-headed cylinder 2 24, the slider 1 25 and the slider 2 26 to move downward, and the slider 1 25 and the slider 2 26 drive the square fixing plate 1 27 and the hollow box 28, the double-headed cylinder 3 29 and the square fixing plate 2 210 to move downward, and then the square fixing plate 2 210 drives the telescopic box 211 and the scraper 212, the blade 1 213 and the blade 2 214 to move downward, and at the same time, the polygonal fixing plate 22 drives the printing screen 12 to move downward, and when the bottom surface of the printing screen 12 moves down to contact the top surface of the paper on the top surface of the conveying unit 11, the four corner bites of the paper are also flush with the edge of the printing screen 12, and the pressing operation of the printing screen 12 on the paper can be completed at this time;

[0049] Then, the air can be ventilated to drive the output end of the double-headed cylinder 24 to move leftward, drive the fixedly connected slider 1 25 to move leftward, and make the slider 1 25 drive the square fixed plate 1 27 and the movable plate 218 and the hollow box 28 to move leftward, so that the hollow box 28 drives the double-headed cylinder 3 29 and the square fixed plate 210, the telescopic box 211 and the scraper 212 to move leftward, and make the scraper 212 drive the blade 1 213 and the blade 2 214 to move leftward, so that the cutouts at the bottom of the scraper 212, the blade 1 213 and the blade 2 214 can contact the inner bottom mesh surface of the printing screen 12 and slide leftward, and under the action of the continuous leftward movement force of the scraper 212, the scraper 212 can gradually contact the ink sprayed on the mesh surface of the printing screen 12, and gradually scrape and squeeze the ink through the mesh imprint of the printing screen 12 to penetrate into the paper printing surface, so as to realize the scraper 212 to move leftward and evenly adhere the paper printing surface;

[0050] Similarly, the other output end of the double-headed cylinder 24 can be driven to move rightward by ventilation, and the fixedly connected slider 26 can be driven to move rightward, and the slider 26 can drive the square fixed plate 1 27, the movable plate 218 and the hollow box 28 to move rightward, and then the hollow box 28 can drive the double-headed cylinder 3 29, the square fixed plate 210, the telescopic box 211 and the scraper 212 to move rightward, and the scraper 212 can drive the blade 1 213 and the blade 2 214 to move rightward, so that the cutouts at the bottom of the scraper 212, the blade 1 213 and the blade 2 214 can contact the inner bottom mesh surface of the printing screen 12. The scraper 212 slides rightward, and under the action of the force of the scraper 212 continuously moving rightward, the scraper 212 can gradually contact the ink sprayed on the mesh surface of the printing screen 12, and gradually scrape and squeeze the ink through the imprint of the printing screen 12 mesh surface to penetrate into the paper printing surface, so that the scraper 212 can move rightward to scrape and adhere the paper printing surface, thereby avoiding incomplete ink printing after paper printing due to insufficient scraping force applied by the one-way disposable scraper 212, resulting in blurred printed patterns, thereby improving the efficiency of screen printing, increasing the force of the scraper 212 to clearly scrape and evenly scrape the ink, and ensuring the normal use of screen printing.

[0051] It should be noted that the left and right movements of the slider 1 25 and the slider 2 26 are performed synchronously, so that when the slider 1 25 drives a group of scrapers 212 and blades 1 213 and blades 2 214 to move left, the slider 2 26 can simultaneously drive another group of scrapers 212 and blades 1 213 and blades 2 214 to move right, thereby realizing that the two groups of scrapers 212 can move in both directions to assist the printing screen 12 and ink to complete the printing of paper, and can also drive the two groups of scrapers 212 to move in both directions by moving the slider 1 25 back to the right and the slider 2 26 back to the left, so that the two groups of scrapers 212 can move left and right to contact and squeeze the scraped piled ink, complete the extrusion and dilution of the ink, avoid the problem of the ink being too hard and the block blocking the grid of the printing screen 12 when the two groups of scrapers 212 scrape the ink for the second time, and improve the convenience of ink printing.

[0052] By setting up a lifting and translational assembly 2, the present scheme can indirectly drive the four scrapers 212 to slide left and right closely against the mesh surface of the printing screen 12 during the left and right movement of the slider 1 25 and the slider 2 26, and to scrape and squeeze the ink sprayed on the mesh surface of the printing screen 12 to move left and right in both directions, so that the scraped and pressed ink can be evenly penetrated and covered on the printing surface of the paper, thereby realizing the four scrapers 212 to perform a two-way moving scraping and printing operation on the ink sprayed on the mesh surface of the printing screen 12, avoiding the problem of part of the ink on the printing surface of the paper not being printed when the scraper 212 is scraping the ink after printing due to insufficient unidirectional scraping force of the scraper 212, resulting in the problem of potholes on the surface of the paper, thereby improving the overall aesthetics of paper printing, enhancing the effect of the scraper 212 in scraping ink evenly in both directions, and ensuring the normal use of paper printing.

[0053] like Figure 6 and Figure 8 As shown, a corner assembly 3 is provided inside the lifting and translation assembly 2;

[0054] The corner assembly 3 includes an arc-shaped slot plate 31 , and the top of the arc-shaped slot plate 31 is fixedly connected to the bottom of the polygonal fixing plate 22 .

[0055] A Z-shaped hollow swing rod 32 is penetrated and slidably connected in the groove wall of the arc groove plate 31, and the outer surface of the bottom front end of the Z-shaped hollow swing rod 32 is penetrated and rotatably connected to the square fixed plate 27, and the bottom front end of the Z-shaped hollow swing rod 32 is penetrated and fixedly connected to the hollow box 28.

[0056] By setting the corner assembly 3, when in use, the square fixed plate 27 can drive the rotatably connected Z-shaped hollow swing rod 32 to move to the left while the slider 25 moves to the left, and the top rear end of the Z-shaped hollow swing rod 32 slides to the left along the inner wall of the arc-shaped slot plate 31. After the top rear end of the Z-shaped hollow swing rod 32 slides to the left until it is flush with the top position of the left oblique slot of the arc-shaped slot plate 31, the rear end of the Z-shaped hollow swing rod 32 can move downward along the left oblique slot wall of the arc-shaped slot plate 31. The front end of the rod 32 is fixed on the hollow box 28. Then, under the action of the downward moving force, the Z-shaped hollow swing rod 32 can make the rear side of the Z-shaped hollow swing rod 32 rotate synchronously, so that the Z-shaped hollow swing rod 32 drives the hollow box 28 to rotate, and further makes the hollow box 28 drive the movable plate 218 and the double-headed cylinder three 29 and the square fixed plate two 210 to rotate, and at the same time, the square fixed plate two 210 drives the telescopic box 211 and the scraper 212, the blade one 213 and the blade two 214 to rotate, and the scraping When the right side plane of the blade 212 rotates 90° and contacts the screen surface of the printing screen 12, the incision height of the rotating scraper 212 can be just flush with the inner top wall of the printing screen 12. At this time, the Z-shaped hollow swing rod 32 also moves downward to be flush with the bottom end of the inclined groove of the arc-shaped groove plate 31, and under the action of the continuous leftward movement force of the slider 25, the scraper 212 and the blade 1 213 and the blade 2 214 can move to the left and penetrate into the edge corner of the printing screen 12, so that the scraper 212 can scrape the ink to the corner of the printing screen 12 at the same time. On the inner mesh surface, the ink can penetrate through the mesh surface of the printing screen 12 and evenly adhere to the edge of the paper, thereby completing the ink printing on the edge corners, avoiding the inability to print at the contact area between the edge frame bottom of the printing screen 12 and the edge corners of the paper, resulting in incomplete ink imprints at the edge corners of the paper, causing the paper to rot and spread after long-term use, resulting in pits and unevenness on the paper surface, thereby increasing the service life of the edge corners of the paper, enhancing the strength of the scraper 212 to scrape and print evenly without dead ends, and ensuring the normal use of screen-printed paper.

[0057] It should be noted that after the scraper 212 turns the corner, if the blade 1 213 has not yet contacted the two side frames of the printing screen 12, the front output end of the bottom of the double-headed cylinder 3 29 can be driven by ventilation to drive the telescopic box 211, the scraper 212 and the blade 1 213 to move forward, and at the same time, the output block at the rear end of the bottom of the double-headed cylinder 3 29 drives another group of telescopic boxes 211, the scraper 212 and the blade 1 213 to move backward, so that the forward-moving blade 1 213 will gradually contact the front side wall of the printing screen 12, so that the rear The moving blade 213 will gradually contact the rear side wall of the printing screen 12, so that the two blades 213 can perform a complete ink printing process on the contact part between the frame of the printing screen 12 and the corner of the paper, avoiding the problem that after the scraper 212 completes the uniform oil printing on the inner bottom wall of the left and right frames of the printing screen 12, the paper pressed by the inner bottom of the front and rear frames cannot be scraped and printed, thereby improving the efficiency of ink printing, enhancing the effect of the scraper 212 and the blade 213 scraping ink and printing corners in a large range, and ensuring the normal complete printing of the paper;

[0058] Secondly, it is explained that when the scraper 212 moves forward, the spring three 217 can push the blade two 214 to extend backward, so that when the scraper 212 moves forward to the frontmost side of the printing screen 12, the blade two 214 can still extend to a length equal to the moving distance of the scraper 212, thereby ensuring that the scraper 212 can still enhance the efficiency of scraping ink printing when scraping ink horizontally and at corners, thereby ensuring the normal printing of various parts of the paper.

[0059] By setting the corner component 3, the present solution can indirectly make the scraper 212 and the blade 213 close to the mesh surface of the inner bottom of the frame of the printing screen 12 to perform corner-type scraping and printing operations under the action of the rotation of the Z-shaped hollow swing rod 32, so as to avoid the problem that after the paper is printed, the larger edge corners of the paper pressed down by the frame of the printing screen 12 are not printed, resulting in incomplete printing of the paper, causing the paper to be worn and spread after long-term use and become unusable. The overall aesthetics of the paper printing is improved, the effect of the scraper 212 and the blade 213 in scraping and printing without dead angles is enhanced, and the normal screen printing is ensured.

[0060] like Fig. 9 and Fig.10 As shown, a lubrication component 4 is provided inside the lifting and translation component 2;

[0061] The moisturizing component 4 includes a glycol agent box 41, the top of which is fixedly connected to the polygonal fixed plate 22, the bottom of which is fixedly connected to a water pump 42, the output end of which is penetrated and fixedly connected with a hose 43, two hoses 43 are provided, and the two hoses 43 are symmetrically distributed, and the output end of the hose 43 is penetrated and fixedly connected with the top rear end of the Z-shaped hollow swing rod 32.

[0062] A second hose 44 is passed through and fixedly connected to the left side of the hollow box 28 . Four second hoses 44 are provided and are symmetrically distributed. The bottom of the second hose 44 passes through and is fixedly connected to the outer surface of the telescopic box 211 .

[0063] The left and right sides of the telescopic box 211 are fixedly connected with a liquid outlet pipe 1 45, and the output port of the liquid outlet pipe 1 45 is aligned with the cut end of the scraper 212. The front and rear sides of the telescopic box 211 are fixedly connected with a liquid outlet pipe 2 46, and the output port of the liquid outlet pipe 2 46 is aligned with the cut end of the blade 1 213.

[0064] By setting the moistening component 4, when working, after the printing screen 12 is lowered to the position of pressing the paper, the water pump 42 can be powered on to start working, so that the input end of the water pump 42 can suck the ethylene glycol in the ethylene glycol box 41 into the pump body, and then the output end of the water pump 42 transports the sucked ethylene glycol to the Z-shaped hollow swing rod 32 through the guidance of the hose 1 43, and then flows into the hollow box 28 through the guidance of the Z-shaped hollow swing rod 32, and then flows into the hose 2 44 through the guidance of the hollow box 28, and the hose 2 44 drains the ethylene glycol into the telescopic box 211, and at the same time, the telescopic box 211 drains the ethylene glycol. The ink is delivered to the liquid outlet pipe 1 45 and the liquid outlet pipe 2 46, so that the liquid outlet pipe 1 45 and the liquid outlet pipe 2 46 can spray liquid to lubricate the contact parts of the scraper 212 and the blade 1 213 with the ink, so as to avoid excessive ink adhesion, resulting in a large amount of blocky ink adhering to the blade surface of the scraper 212 and the blade 1 213, causing interference with the secondary ink scraping printing of the scraper 212 and the blade 1 213, improving the efficiency of ink softening and penetration, strengthening the strength of the non-adhesion fast ink scraping printing of the scraper 212 and the blade 1 213, increasing the clarity of the dark color covering the paper after the ink is softened, and ensuring the normal clear printing of the paper.

[0065] It should be noted that the ethylene glycol agent can not only improve the spreading ability of the ink on the paper and make the ink color more uniform, but also reduce the adhesion of the ink to the scraper 212 and the blade 213, and play a certain lubricating effect, so that the scraper 212 and the blade 213 can achieve twice the result with half the effort in the process of scraping and printing the ink.

[0066] By setting up the lubrication component 4, the present scheme can indirectly enable the liquid outlet pipe 1 45 and the liquid outlet pipe 2 46 to spray liquid to lubricate the blade surface of the scraper 212 and the blade 1 213 under the action of the continuous output force of the water pump 42, so as to avoid the problem that the scraper 212 and the blade 1 213 will adhere to the ink and the paper print will be blurred due to the influence of the residual attached ink after the scraper 212 and the blade 1 213 have been scraping ink for a long time. The effectiveness of ink softening, dilution and penetration is improved, the strength of the scraper 212 and the blade 1 213 in non-resistance and non-adhesion scraping ink printing is enhanced, the effect of the printing screen 12 on non-blocking and penetrating ink print is increased, and the normal clear printing of paper is ensured.

[0067] like Figures 11 to 13 As shown, an ultraviolet light component 5 is provided on the left side of the lifting and translation component 2;

[0068] The ultraviolet light component 5 includes a cylinder four 51, which is fixedly connected to the top of the polygonal fixing plate 22. The outer surface of the output end of the cylinder four 51 penetrates and is slidably connected to the polygonal fixing plate 22. The output end of the cylinder four 51 is fixedly connected to a power drive box 53, and the right side of the power drive box 53 is slidably connected to a slide rail 52. There are two slide rails 52, and the two slide rails 52 are symmetrically distributed. The right sides of the two slide rails 52 are fixedly connected to the left side of the polygonal fixing plate 22. The bottom of the power drive box 53 is fixedly connected to an ultraviolet LED lamp 54, and the LED lamp surface of the bottom of the ultraviolet LED lamp 54 is opposite to the top surface of the transmission unit 11.

[0069] By setting the ultraviolet light component 5, when working, after the scraper 212 completes printing on the printing surface of the paper, the output end of the cylinder 1 21 can be driven to extend upward, drive the polygonal fixing plate 22 to drive the printing screen 12 and the ultraviolet light component 5 to move upward, and gradually loosen the printed paper. After the bottom printing screen of the printing screen 12 is separated from the paper, the cylinder 1 21 stops extending, and then the power is turned on to drive the conveying unit 11 to convey the printed paper to the left to the position directly below the ultraviolet LED lamp 54, and then the conveying unit 11 stops moving;

[0070] Then, turn on the power supply of the power drive box 53, and turn on the power to drive the LED lamp at the bottom of the ultraviolet LED lamp 54 to start lighting, so that the ultraviolet LED lamp 54 can perform ultraviolet irradiation operation on the printed paper ink. When the ultraviolet LED lamp 54 irradiates the smaller ink imprint on the top surface of the paper, the output end of the cylinder 4 51 can be ventilated to extend downward, drive the fixedly connected power drive box 53 to move downward, and make the power drive box 53 drive the ultraviolet LED lamp 54 to move downward, so that the ultraviolet light of the ultraviolet LED lamp 54 after moving downward can gradually focus on one point, so that the ink imprint on the paper irradiated by the point can be quickly Rapid curing can be achieved, so that the ultraviolet LED lamp 54 can switch between point-type irradiation curing operation and covering irradiation curing operation for different forms of ink imprints on the printed paper, avoiding the influence of the fixed ultraviolet irradiation direction of the scraper 212 and the blade 213 after printing, resulting in a decrease in the curing quality of the printed surface of the paper, the paper being penetrated and soaked by ink, and the problem of reducing the curing efficiency of the paper after printing. The effectiveness of uniform curing of the paper after printing is improved, the flexibility of the ultraviolet LED lamp 54 for ultraviolet irradiation curing is enhanced, the range of the ultraviolet LED lamp 54 for curing different forms of ink is increased, and the normal use of the irradiation curing of the paper after printing is guaranteed.

[0071] Method of use: When the present invention is used, the workbench 1 is first placed at a preset printing process position, and then ethylene glycol is injected into the ethylene glycol agent box 41. After the inner cavity of the ethylene glycol agent box 41 is filled, the injection operation is stopped, and then the ink is poured into the grid surface of the printing screen 12. Then, the output end of the cylinder 21 in the lifting and translational component 2 is powered on to shrink downward, so that the scraper 212 can be driven to perform a two-way moving scraping and adhesion operation on the ink poured into the printing screen 12, and then the corner component 3 drives the scraper 212 to perform a corner extrusion and smoothing operation, and then the moisturizing component 4 can drive the scraper The cut surface of 212 is sprayed with ethylene glycol for dilution, so that the ultraviolet light component 5 drives the ultraviolet LED lamp 54 to perform a lifting ultraviolet light curing operation. After the scraper 212 completes printing on the paper, the power is turned on again to drive the output end of the cylinder 21 to extend upward, so that the scraper 212 can be moved back to the initial position. If there is still unprinted paper, the unprinted paper can be transported to the bottom of the printing screen 12 again, and the above steps are repeated. After all the papers are printed, the output shaft of the cylinder 21 is stopped, the device stops running, the printed paper is taken out, and the printing is completed.

[0072] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
