Description

Technical Field

[0001] The utility model relates to the technical field of double-sided printing, in particular to a visual positioning double-sided jet printer. Background Art

[0002] At present, printing devices that can realize double-sided printing simultaneously have been developed. In some application scenarios, two images that are mirror-symmetrical or correspond to each other in other ways need to be printed on the front and back sides of the printing material, and the printing material is attached to the surface of a light box, for example, after printing.

[0003] After searching, the disclosure (announcement) number is: CN115904278A, which discloses a novel double-sided printing method, system, device and storage medium. The method sets identification positioning points on a first material screen and a second material screen, prints a first original image on the first material screen according to the first material screen positioning points, flips the printed first original image to the second material screen, obtains the screen information of the second material screen, extracts the position information of the identification positioning points of the second material screen according to the screen information, adjusts the second original image according to the identification positioning points position information of the second material screen, and prints the adjusted second original image on the second material screen. The method can ensure that the first original image and the second original image are accurately printed according to the set first material screen identification positioning points and the second material screen identification positioning points, thereby ensuring the accuracy of the alignment.

[0004] The above technical solution has the following shortcomings:

[0005] Although the above technical solution can realize double-sided printing, it cannot realize double-sided printing at the same time, which leads to the problem that the printing efficiency is still low.

[0006] Especially when the printing medium is elastic, such as large-format UV double-sided inkjet, elasticity means that when printing on one side during double-sided printing, the printing position on the other side is prone to positional deviation due to the order of printing the front and back sides and the presence of pulling tension.

Therefore, the purpose of the present invention is to provide a visual positioning double-sided inkjet printer, which can realize double-sided printing and realize deviation correction by visual alignment when printing elastic media.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A visual positioning double-sided inkjet printer comprises two frames, a first crossbeam frame and a second crossbeam frame arranged at staggered heights inside the two frames, transmission wheels are rotatably arranged at both ends of the first crossbeam frame and the second crossbeam frame, transmission belts are sleeved on the surfaces of the first crossbeam frame and the second crossbeam frame, each of the transmission belts matches with two corresponding transmission wheels, a slider is fixedly arranged on the surface of each transmission belt, a first spray car system and a second spray car system are fixedly arranged on the top of the two sliders, the two sliders are slidably arranged on the surfaces of the first crossbeam frame and the second crossbeam frame, and a visual scanning system and a visual scanning supplementary light source are fixedly arranged on the top of the second spray car system.

[0010] Preferably, drive motors are fixedly mounted on the ends of the first crossbeam frame and the second crossbeam frame, and output ends of the two drive motors are fixedly connected to corresponding transmission wheels, respectively.

[0011] Preferably, a first printing platform and a second printing platform are arranged between the first crossbeam frame and the second crossbeam frame, the first printing platform matches the first spray car system, and the second printing platform matches the second spray car system.

[0012] Preferably, a printing medium is arranged between the first inkjet system and the second inkjet system, and the printing medium passes between the first printing platform and the second printing platform.

[0013] Preferably, both of the two driving motors are reduction motors.

[0014] Preferably, the printing medium is slidably fitted to the surfaces of the first printing platform and the second printing platform.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] The utility model realizes double-sided printing and the effect of correcting the deviation of printing elastic media by visual alignment. The first spray car system and the second spray car system are respectively installed by the first crossbeam frame and the second crossbeam frame which are arranged at staggered heights. At the same time, the visual scanning system and the visual scanning supplementary light source which are arranged on the top of the second spray car system can track and locate the reference point.

[0025] The utility model embodiment discloses a visual positioning double-sided inkjet printer.

[0026] Embodiment 1

[0027] The utility model provides Figure 1-4A visual positioning double-sided inkjet printer shown in the figure comprises two frames 10, a first crossbeam frame 1 and a second crossbeam frame 4 which are staggered in height inside the two frames 10, transmission wheels 11 are rotatably arranged at both ends of the first crossbeam frame 1 and the second crossbeam frame 4, transmission belts 12 are sleeved on the surfaces of the first crossbeam frame 1 and the second crossbeam frame 4, each transmission belt 12 matches with the corresponding two transmission wheels 11, a slider 14 is fixedly arranged on the surface of each transmission belt 12, a first spray car system 2 and a second spray car system 5 are fixedly arranged on the top of the two sliders 14, respectively, the two sliders 14 are slidably arranged on the surfaces of the first crossbeam frame 1 and the second crossbeam frame 4, a visual scanning system 7 and a visual scanning supplementary light source 8 are fixedly arranged on the top of the second spray car system 5, the first spray car system 2 and the second spray car system 5 can be installed respectively by using the first crossbeam frame 1 and the second crossbeam frame 4 which are staggered in height, and the visual scanning system 7 and the visual scanning supplementary light source 8 arranged on the top of the second spray car system 5 can be used to track and locate the reference point.

[0028] Printing elastic media is easy to deform and has a certain degree of transparency. The visual scanning system can identify the mark printed on the back side (such as the cross mark printed on both sides of the printing medium from top to bottom) by scanning the image on the back side of the material; the position of this mark is used as the reference deviation. If the deviation is not large, the correction will not be started, and the deviation range can be set as needed. For example, if the deviation is within 5%, no correction is required, and if the deviation exceeds 5%, the front printing effect is corrected so that the front printing effect matches the expected position. At the same time, it can be used for inspection, with another mark printed on the front side of the material as the inspection mark. If the mark on the back side coincides with the inspection mark on the front side, the printing is qualified.
