Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a double-sided inspection device for printed materials. Background Technology

[0002] In the printing process, quality control of printed materials is essential. This quality control involves two stages: pre-press and post-press. Pre-press involves using image verification software to check the content of the document before and after editing and identify errors during the editing process. Post-press involves using an offline inspection system to capture high-precision images of the printed material and compare them with PDF files to automatically detect the integrity of the printed content. This can identify printing defects such as plate scratches, missing characters, and text errors. The offline inspection system can also be used for random checks of the printed material quality to prevent continuous defective products. Therefore, a double-sided inspection device for printed materials is required.

[0003] Chinese patent document CN221100537U discloses a double-sided inspection device for printed materials. The device includes a frame, a first suction plate, a second suction plate, a flipping mechanism, and an image acquisition mechanism. The first suction plate is mounted on the frame and is used to hold the printed material to be inspected. The second suction plate is flip-mounted on the frame and is used to flip and adsorb the printed material located on the first suction plate. The flipping mechanism is located on the side of the frame and is used to drive the second suction plate to flip. The image acquisition mechanism is slidably mounted on the frame and is used to move to acquire images of the printed material adsorbed on the first or second suction plate. This invention, through the cooperation of the first suction plate, the second suction plate, the flipping mechanism, and the image acquisition mechanism, can automatically flip printed materials, thereby achieving automatic double-sided inspection of printed materials during offline inspection.

[0004] The existing technology has the following problems:

[0005] Double-sided inspection equipment for printed materials is inconvenient for transporting printed materials, thus affecting inspection efficiency. Furthermore, the guide plate cannot be adjusted according to the size of the printed materials, which affects the transport of the printed materials by the suction plate. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 As shown, a double-sided inspection device for printed materials includes a support frame 1, a support frame 2 fixedly installed on the right side of the support frame 1, conveyor belts 3 fixedly connected to the upper surfaces of both support frame 1 and support frame 2, position adjustment components 4 fixedly connected to the upper surfaces of both conveyor belts 3, material feeding components 5 fixedly connected to the upper surfaces of both conveyor belts 3 and located between the two position adjustment components 4, a fixed frame 6 fixedly connected to the rear of the support frame 1, and a touch screen all-in-one machine 7 fixedly connected to the front of the upper part of the fixed frame 6, with the touch screen all-in-one machine 7 located above the position adjustment components 4 and the material feeding components 5.

[0028] First, adjust the two position adjustment components 4 according to the size of the printed matter. Then, under the action of the right conveyor belt 3, the printed matter can move to the left. Then, under the action of the right material conveying component 5, the printed matter can move between the two cameras. At this time, the patterns on the top and bottom sides of the printed matter can be photographed and identified by the camera and the touch screen all-in-one machine 7. Then, the photographed printed matter is moved to the upper surface of the left conveyor belt 3 by the left material conveying component 5, so that the qualified or unqualified printed matter is transported out.

[0029] like Figure 2 As shown, a material collection box 12 is snapped onto the upper surface of the support frame 1 and the material collection box 12 is located in front of the conveyor belt 3. A rejection solenoid valve 11 is fixedly connected to the upper surface of the support frame 1 and the rejection solenoid valve 11 is located behind the conveyor belt 3. A transparent support plate 13 is fixedly connected to the opposite surfaces of the two conveyor belts 3.

[0030] When the touch screen all-in-one machine 7 detects that the printed material is unqualified, the solenoid valve 11 is used to blow the printed material into the collection box 12, thereby collecting the unqualified products for centralized processing.

[0031] like Figure 3As shown, a top camera 61 is fixedly installed on the front of the mounting bracket 6 and the top camera 61 is located on the right side of the touch screen all-in-one machine 7. A top light source 62 is fixedly installed on the front of the mounting bracket 6 and the top light source 62 is located directly below the top camera 61. A bottom light source 63 is fixedly installed on the front of the mounting bracket 6 and the bottom light source 63 is located below the transparent support plate 13. A bottom camera 64 is fixedly connected to the front of the mounting bracket 6 and the bottom camera 64 is located directly below the bottom light source 63.

[0032] By utilizing the top light source 62 and the bottom light source 63, when the printed material is located on the upper surface of the transparent support plate 13, both its top and bottom sides can be photographed simultaneously by the top camera 61 and the bottom camera 64 and uploaded to the interior of the touch screen all-in-one machine 7. The touch screen all-in-one machine 7 then compares the images to perform double-sided inspection of the printed material.

[0033] like Figure 4 As shown, the material conveying assembly 5 includes a fixed shell 51, the lower surface of which is fixedly connected to the upper surface of the conveyor belt 3, an electric push rod 52 is fixedly connected to the inner wall of the fixed shell 51, a movable frame 53 is fixedly connected to the output end of the electric push rod 52, and the outer wall of the movable frame 53 is movably sleeved with the inner wall of the upper part of the fixed shell 51; two electric push rods 54 are fixedly connected to the lower surface of the movable frame 53, and an adsorption plate 55 is fixedly connected to the output end of the two electric push rods 54.

[0034] The electric push rod 54 causes the adsorption plate 55 to move down to the upper surface of the printed material. Then, the air pump causes the printed material to be adsorbed onto the lower surface of the adsorption plate 55. Finally, the electric push rod 52 causes the adsorption plate 55 to move the printed material to the upper surface of the transparent support plate 13, thus facilitating the transportation and movement of the printed material. Since there are two adsorption plates 55, they can work with two conveyor belts 3 to improve the efficiency of printing material inspection.

[0035] Guide rods 56 are slidably connected to the inner cavities of the front and rear parts of the movable frame 53. The left and right sides of the two guide rods 56 are fixedly connected to the inner wall of the fixed shell 51, respectively.

[0036] The guide rod 56 enables the movable frame 53 to move stably within the inner wall of the fixed shell 51, thus providing guidance and support.

[0037] like Figure 5 , Figure 6As shown, the position adjustment assembly 4 includes a U-shaped frame 41. The lower surface of the U-shaped frame 41 is fixedly connected to the upper surface of the conveyor belt 3. A threaded rod 42 is rotatably connected to the inner cavity of the upper part of the U-shaped frame 41. Limiting guide plates 44 are threadedly connected to the outer walls of the front and rear parts of the threaded rod 42. The lower surfaces of the two limiting guide plates 44 overlap with the upper surface of the conveyor belt 3 respectively. A guide rod 45 is slidably connected to the inner cavity of the upper part of the two limiting guide plates 44, and the guide rod 45 is located below the threaded rod 42. The front and rear sides of the guide rod 45 are fixedly connected to the inner wall of the U-shaped frame 41. A rotating wheel 43 is fixedly connected to the front of the threaded rod 42, and the rotating wheel 43 is located in front of the U-shaped frame 41.

[0038] By rotating the wheel 43, the threaded rod 42 can be rotated, thereby allowing the two limiting guide plates 44 to move towards each other under the guidance of the guide rod 45. This allows the distance between the two limiting guide plates 44 to be adjusted according to the size of the printed material, facilitating the guidance of the printed material by the two limiting guide plates 44.

[0039] The working principle of this utility model is as follows: First, by rotating the rotating wheel 43, the threaded rod 42 can rotate, thereby allowing the two limiting guide plates 44 to move towards each other under the guidance of the guide rod 45. This allows the distance between the two limiting guide plates 44 to be adjusted according to the size of the printed matter. Then, under the action of the right-side conveyor belt 3, the printed matter can move to the left and be placed below the suction plate 55. Then, by the action of the electric push rod 54, the suction plate 55 can be moved down to the upper surface of the printed matter. Then, by the action of the air pump, the printed matter can be adsorbed onto the lower surface of the suction plate 55. Finally, by the action of the electric push rod 52, the suction plate 55 can hold the printed matter. The printed product moves to the upper surface of the transparent support plate 13. At this time, the top light source 62 and the bottom light source 63 enable the printed product to be photographed on both sides of the upper and lower surfaces by the top camera 61 and the bottom camera 64, and the images are uploaded to the inside of the touch screen all-in-one machine 7. The touch screen all-in-one machine 7 then compares the images to perform double-sided inspection of the printed product. Next, the printed product is moved to the upper surface of the left conveyor belt 3 by the left part suction plate 55. When the touch screen all-in-one machine 7 detects that the printed product is unqualified, the printed product is blown into the collection box 12 by the action of the rejection solenoid valve 11, thereby collecting the unqualified products.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
