Description

Technical Field

[0001] The invention relates to the field of printing equipment, in particular to an automated UV color printer. Background Art

[0002] UV printer, also known as universal flatbed printer or flatbed printer, has broken through the bottleneck of digital printing technology. It is a high-tech full-color digital printing machine without platemaking. UV printer is not restricted by any materials and can be used for color printing on T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various signs, crystal, PVC, acrylic, metal, plastic, stone, leather and other surfaces, without platemaking, and printing can be completed in one time. The colors are bright and rich, wear-resistant, UV-proof, simple and convenient to operate, and the printing image speed is fast. It fully meets industrial printing standards and has a wide range of applications. The principle of UV printer is that the ultraviolet waves emitted by the LED cold light source react with the photosensitive curing agent in the UV ink, causing the pigment molecules in the UV ink to solidify on the surface of the material. The weather resistance and water resistance of the UV-curable ink are superior. Therefore, the printed matter can be used for outdoor advertising, tile pattern printing, etc. Compared with ordinary water-soluble ink, the printing range of the printed matter is greatly expanded.

[0027] The automatic feeding assembly includes a first conveyor belt 7, which is arranged on the right side of the top of the base 1. The first conveyor belt 7 is electrically connected to the PLC control panel 6, that is, the PLC control panel 6 can control the switch and forward and reverse rotation of the first conveyor belt 7 according to a preset program. The first conveyor belt 7 is located below the nozzle 4 and the ultraviolet lamp 5. A feed port 8 is provided at the right end of the housing 2. The right end of the first conveyor belt 7 passes through the feed port 8, that is, the staff can convey the print material to be printed by the first conveyor belt 7, so that the print material passes under the nozzle 4 and under the ultraviolet lamp 5 in turn during the conveying process, so that the nozzle 4 can perform inkjet printing on the print material, and then the ink printed on the surface of the print material is irradiated by ultraviolet rays and solidified on the surface of the print material, so that the single-sided printing operation can be completed;

[0028] The flip assembly includes a hydraulic cylinder 9, which is fixedly mounted on the top upper surface of the housing 2. The hydraulic cylinder 9 is electrically connected to the PLC control panel 6, that is, the PLC control panel 6 can control whether the hydraulic cylinder 9 is doing work according to a preset program. The output shaft of the hydraulic cylinder 9 vertically penetrates the top of the housing 2, and the output shaft of the hydraulic cylinder 9 is fixedly mounted with a mounting plate 10, so when the hydraulic cylinder 9 is doing work, it can directly drive the mounting plate 10 to reciprocate up and down, a reducer 11 is fixedly mounted on the rear end of the mounting plate 10, and a servo motor 12 is fixedly mounted on the rear end of the reducer 11, and the servo motor 12 is electrically connected to the PLC control panel 6, that is, the PLC control panel 6 can control whether the servo motor 12 is doing work according to a preset program, the output shaft of the servo motor 12 is fixedly connected to the input shaft of the reducer 11, the output shaft of the reducer 11 penetrates the mounting plate 10 forward, and the output shaft of the reducer 11 is fixedly mounted with a C-shaped plate 13, so when the servo motor 12 is doing work, under the deceleration action of the reducer 11, the reducer 11 can be used to reduce the speed of the servo motor 12.

The two second conveyor belts 14 are located on the left side of the first conveyor belt 7, that is, the two second conveyor belts 14 can rotate 180° in both directions synchronously with the C-shaped plate 13. The second conveyor belt 14 located at the bottom corresponds to the first conveyor belt 7 horizontally, so the printed material printed on one side can be conveyed between the two second conveyor belts 14 by the first conveyor belt 7, and then continued to be conveyed by the second conveyor belt 14. The surface of the second conveyor belt 14 located at the top is provided with a rubber strip 29, which can play a role in clamping the printed material to prevent the printed material from falling due to gravity when the two second conveyor belts 14 rotate in both directions to a vertical state, so that the structural design of the present invention is reasonable. The two second conveyor belts 14 are electrically connected to the PLC control panel 6, that is, the PLC control panel 6 can control whether the second conveyor belt 14 does work according to a preset program;

[0029] In summary, when the single-sided printed material is conveyed to the middle of the two second conveyor belts 14, the PLC control panel 6 controls the two second conveyor belts 14 to stop working according to the preset program. At this time, the printed material is clamped by the rubber strip 29. Then the PLC control panel 6 controls the hydraulic cylinder 9 to work according to the preset program, first driving the two second conveyor belts 14 to move up, so that the two second conveyor belts 14 have enough space to rotate. Then the PLC control panel 6 controls the servo motor 12 to work according to the preset program, driving the two second conveyor belts 14 to rotate 180°, so that the printed material is turned over, that is, the printed material is automatically flipped, and the direction of the two second conveyor belts 14 can also be changed. Then the PLC control panel 6 controls the first conveyor belt 7 to reverse according to the preset program. The first conveyor belt 7 is used to rotate and start the two second conveyor belts 14 again, so that the printed matter printed on one side is automatically turned over and then conveyed to the first conveyor belt 7 by the two second conveyor belts 14, and then conveyed to the right by the first conveyor belt 7. When conveyed to the right side of the nozzle 4, the PLC control panel 6 controls the first conveyor belt 7 to rotate forward again according to the preset program, so that the turned printed matter is conveyed to the left again, so that it passes under the nozzle 4 and under the ultraviolet lamp 5 again, that is, it is printed again, and then it is conveyed to the left by the first conveyor belt 7 and the second conveyor belt 14. That is, the present invention can perform continuous printing operations on the printed matter, automatically turn over after printing on one side, and then print on the other side, so as to achieve the effect of double-sided printing, without the need for manual turning by the staff, thereby improving the printing efficiency;

[0030] The first unloading assembly includes a third conveyor belt 15, which is arranged on the left side of the top of the base 1. The third conveyor belt 15 is electrically connected to the PLC control panel 6, that is, the PLC control panel 6 can control whether the third conveyor belt 15 works according to a preset program. The second conveyor belt 14 is located between the first conveyor belt 7 and the third conveyor belt 15, that is, the printed matter after double-sided printing can be continuously conveyed to the left by the second conveyor belt 14 to the third conveyor belt 15, and then continued to be conveyed by the third conveyor belt 15. A first unloading port 16 is opened at the left end of the shell 2, and the left end of the third conveyor belt 15 passes through the first unloading port 16. A first material receiving box 17 is arranged at the left end of the top of the base 1, and the first material receiving box 17 is located below the left end of the third conveyor belt 15, that is, the printed matter that has been printed on both sides and has passed the first unloading port 16 is unloaded into the first material receiving box 17;

[0031] The detection component includes a camera 18, which is arranged at the top of the inner wall of the shell 2, and the camera 18 is located above the left end of the first conveyor belt 7, so when the printed material is printed on one side and printed on both sides, it will be photographed by the camera 18 during the process of being conveyed to the left on the first conveyor belt 7. A processor 19 is arranged at the front end of the shell 2, and the camera 18 is connected to the processor 19 by data line, and the processor 19 is connected to the PLC control panel 6 by data line. The processor 19 includes an image acquisition module 20, a processing chip 21, a data library 22 and a memory 23. The camera 18 is connected to the image acquisition module 20 by data line, that is, the image acquisition module 20 can collect the image taken by the camera 18, the image acquisition module 20 is connected to the processing chip 21 by data line, and the data library 22 is connected to the processing chip 21 by data line. In the present invention, The data library 22 is a database for establishing print defect images, so after receiving the image sent by the image acquisition module 20, the processing chip 21 can extract defect features by a traditional image processing algorithm, and use a neural network algorithm to identify defects (the defect feature extraction and defect identification methods adopted by the present invention are both prior arts and are not described in detail here), and then compare and analyze with the print defect image database established in the data library 22, and obtain information on whether the print is qualified. The processing chip 21 is connected to the memory 23 by a data line, so the processing chip 21 can store the comparison result, that is, the information on whether the print is qualified, in the memory 23. The processing chip 21 is connected to the PLC control panel 6 by a data line, so the processing chip 21 can send the information on whether the print is qualified to the control PLC control panel 6;

[0032] The second unloading component includes an electric telescopic rod 24, the rear end of which is fixedly mounted on the rear side of the inner wall of the shell 2, and the electric telescopic rod 24 is electrically connected to the PLC control panel 6, that is, when the PLC control panel 6 receives the information sent by the processor 19 that the single-sided printing of the printed matter is unqualified or the printing is unqualified after turning over, the PLC control panel 6 controls the electric telescopic rod 24 to work according to a preset program, and when the single-sided printing of the printed matter is already unqualified, the PLC control panel 6 no longer controls the operation of turning over the printed matter and performing a second printing according to the preset program, but instead continues to convey the unqualified printed matter from the two second conveyor belts 14 to the third conveyor belt 15 to the left, thereby achieving the effect of avoiding ink waste, and the output shaft of the electric telescopic rod 24 is fixedly mounted with a push plate 25, and the push plate 25 is located on the right side of the third conveyor belt 15 The rear end of the third conveyor belt 15 is provided with a push plate 25, and the horizontal plane of the push plate 25 is slightly higher than the horizontal plane of the third conveyor belt 15. Therefore, when the electric telescopic rod 24 works, it can drive the push plate 25 to move forward, thereby pushing the unqualified printed materials transmitted to the third conveyor belt 15 forward. A guide plate 26 is fixedly installed on the front side of the right end of the third conveyor belt 15, so that the unqualified printed materials are pushed onto the guide plate 26, that is, they are separated from the third conveyor belt 15. A second discharge port 27 is provided at the front end of the shell 2, and the front end of the guide plate 26 passes through the second discharge port 27. A second material receiving box 28 is provided at the front end of the top of the base 1. The second material receiving box 28 is located below the front end of the guide plate 26. Therefore, when the number of unqualified printed materials pushed onto the guide plate 26 increases, the unqualified printed materials at the back on the guide plate 26 will push out the front ones, thereby falling into the second material receiving box 28.

[0033] The use process of the present invention is as follows: the staff first sends the printed material to be printed to the left by the first conveyor belt 7, so that the printed material passes under the nozzle 4 and under the ultraviolet lamp 5 in turn during the conveying process, so that the nozzle 4 can perform inkjet printing on the printed material, and then the ink printed on the surface of the printed material is irradiated by ultraviolet rays and solidified on the surface of the printed material, so that the single-sided printing operation is completed, and then the printed material with single-sided printing continues to be conveyed to the left by the first conveyor belt 7 to the bottom of the camera 18. At this time, the PLC control panel 6 controls the first conveyor belt 7 to stop according to the preset program to ensure that the printed material is in a static state when the camera 18 shoots and takes images of the printed material. The image acquisition module 20 acquires the image taken by the camera 18 and then uploads it to the processing chip 21. After receiving the image sent by the image acquisition module 20, the processing chip 21 can extract defect features by a traditional image processing algorithm, and use a neural network algorithm to identify defects (the defect feature extraction and defect identification methods used in the present invention are both existing technologies and will not be repeated here), and then compare and analyze with the database of print defect images established in the data library 22, and obtain information on whether the print material is printed properly;

[0034] If the single-sided printing is qualified, the PLC control panel 6 will restore the rotation of the first conveyor belt 7 according to the preset program, so that the first conveyor belt 7 will continue to convey the printed matter with single-sided printing to between the two second conveyor belts 14. When the printed matter with single-sided printing is conveyed to the middle of the two second conveyor belts 14, the PLC control panel 6 will control the two second conveyor belts 14 to stop working according to the preset program. At this time, the printed matter is clamped by the rubber strip 29. Then the PLC control panel 6 will control the hydraulic cylinder 9 to work according to the preset program, first driving the two second conveyor belts 14 to move up, so that the two second conveyor belts 14 have enough space to rotate. Then the PLC control panel 6 will control the servo motor 12 to work according to the preset program, driving the two second conveyor belts 14 to rotate 180°, so that the printed matter is turned over, that is, the printed matter is automatically flipped, and the direction of the two second conveyor belts 14 can also be changed. Then the PLC control panel 6 will control the two flipped second conveyor belts 14 to move down to a height corresponding to the level of the first conveyor belt 7 again. Then the PLC control panel 6 will control the two flipped second conveyor belts 14 to move down to a height corresponding to the level of the first conveyor belt 7. Assume that the program controls the first conveyor belt 7 to rotate in the opposite direction, and starts the two second conveyor belts 14 again, so that the printed matter printed on one side is automatically turned over and conveyed to the first conveyor belt 7 by the two second conveyor belts 14, and then conveyed to the right by the first conveyor belt 7. When the printed matter is conveyed to the first conveyor belt 7, the PLC control panel 6 controls the two second conveyor belts 14 to perform the above-mentioned turning action again according to the preset program, but to rotate 180° in the opposite direction and restore to the original position. When the printed matter printed on one side after turning over is conveyed to the right side of the nozzle 4, the PLC control panel 6 controls the first conveyor belt 7 to rotate forward again according to the preset program, so that the turned over printed matter is conveyed to the left again, so that it passes under the nozzle 4 and under the ultraviolet lamp 5 again, that is, it is printed again, and then it is conveyed to the left by the first conveyor belt 7 and the second conveyor belt 14. That is, the present invention can perform continuous printing operations on the printed matter, automatically turn over after printing on one side, and then print on the other side, so as to achieve the effect of double-sided printing, without the need for manual turning by the staff, thereby improving the printing efficiency.

[0035] If the single-sided printing is unqualified, the PLC control panel 6 restores the rotation of the first conveyor belt 7 according to the preset program, so that the first conveyor belt 7 continues to convey the printed matter with single-sided printing to between the two second conveyor belts 14. The PLC control panel 6 no longer controls the operation of turning over the printed matter and performing a second printing according to the preset program, but continues to convey the unqualified printed matter from the two second conveyor belts 14 to the left to the third conveyor belt 15, thereby achieving the effect of avoiding ink waste. Then the PLC control panel 6 controls the electric telescopic rod 24 to work according to the preset program, so that the unqualified printed matter is pushed out of the third conveyor belt 15 by the push plate 25, and pushed onto the guide plate 26, and then falls into the second material receiving box 28 from the second unloading port 27;

[0036] When the printed material that is turned over and printed again, that is, the printed material after double-sided printing, moves to the left below the camera 18 on the first conveyor belt 7, similarly, the printed material after turning over and printing is detected again to detect whether the printing is qualified. If the turning over and printing are qualified, the printed material is directly conveyed by the two second conveyor belts 14 to the third conveyor belt 15, and then discharged from the first unloading port 16 to the first receiving box 17. If the turning over and printing are unqualified, similarly, the printed material is pushed out of the third conveyor belt 15 by the pushing plate 25, and pushed onto the guide plate 26, and then dropped from the second unloading port 27 to the second receiving box 28. Therefore, during the printing process of the printed material, after the printing of one side of the printed material is completed and after the double-sided printing is completed, the present invention will automatically detect whether the printing of the printed material is qualified, without the need for naked eye observation by the staff, reducing the workload of the staff and avoiding the waste of ink. It has a high degree of automation, good use effect, and is suitable for promotion.

[0037] The above is only a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
