Description

Technical Field

[0001] The utility model relates to the technical field of printed matter detection, in particular to a digital printing quality detection mechanism. Background Art

[0002] Refers to various printed products, which is a general term for various finished products produced using printing technology. In daily life, people come into contact with newspapers, books, magazines, maps, posters, advertisements, envelopes, letterheads, file bags, trademarks, labels, business cards, invitations, banknotes, greeting cards, desk calendars, wall calendars, picture albums, various cards, packaging boxes, gift boxes, circuit boards, etc., all of which belong to the category of printed products. Printed products are almost everywhere in people's clothing, food, housing, and transportation. It is very closely related to people's lives. Therefore, the quality inspection of printed products is very important;

[0003] After searching, the applicant found that a Chinese patent disclosed "a color difference quality detection mechanism for printed product production", and its publication (announcement) number is "CN 218691723 U". This patent mainly sets a suction cup, and the processor compares the image taken by the high-definition camera with the hue standard data. After analyzing the printed products with unqualified color difference quality, the slider is controlled to slide onto the printed product to start the suction cup to absorb the unqualified printed product, and then slide to one side and cut off the air, so that the unqualified printed product falls into the collection box, so that there is no need to manually collect the unqualified products, reducing the waste of manpower. However, directly placing the unqualified printed products on the placement rack without applying downward pressure will take up more space, resulting in a reduction in the number of unqualified printed products that can be placed in the collection box, resulting in the need for frequent removal, which reduces the use effect. For this reason, we propose a digital printing quality detection mechanism. Utility Model Content

[0026] Please refer to the attached Figure 5 A moving groove 18 is provided on the front side of the upper end of the detection conveyor frame 3, and a moving shaft 19 is slidably connected inside the moving groove 18. The moving shaft 19 can rotate inside the moving groove 18, and the moving shaft 19 extends to the outside of the moving groove 18.

[0027] In this embodiment, the guide plate 20 can be used to guide the position of the printed product, so that the printed product can be better moved to the middle of the supporting frame 4, so as to better detect the quality of the printed product.

[0028] During use, when the angle of the guide plate 20 needs to be adjusted, the threaded column 22 can be rotated, and the threaded column 22 can be rotated on the fixed plate 21 to prompt the threaded column 22 to move.

[0029] Working principle:

[0030] The first step is that when the servo motor 15 drives the reciprocating screw rod 6 to move the transfer paper suction head 7, the connecting steel rope 14 will be pulled, and then the redirecting shaft 10 will be used to change the pulling direction of the connecting steel rope 14, so that the lower pressure plate 13 is lifted and lowered in the lifting slide rail 11. The split rope 16 can increase the stability of the lower pressure plate 13 during lifting and lowering. After the transfer paper suction head 7 places unqualified printed products in the paper storage rack 2, the lifting and lowering of the lower pressure plate 13 can be used to press down the unqualified printed products in the paper storage rack 2. In this way, multiple unqualified printed products can be pressed down, thereby reducing the area occupied by multiple unqualified printed products and increasing the number of unqualified printed products that can be stored in the paper storage rack 2.

[0031] The second step is to rotate the threaded column 22 when the angle of the guide plate 20 needs to be adjusted. The threaded column 22 can be rotated on the fixed plate 21 to move the threaded column 22. The movement of the threaded column 22 can synchronously push the corner axis 17 and the guide plate 20 to move, and the end of the guide plate 20 away from the corner axis 17 is rotatably connected to the movable axis 19, so that the angle of the guide plate 20 can be changed. In this way, printed products of different widths can be effectively guided, and the printed products can be better moved to the middle of the detection conveyor frame 3, so as to facilitate the detection of the quality of the printed products.
