Description

Technical Field

[0001] This utility model belongs to the field of printed matter inspection technology, and specifically relates to a visual inspection device for printed matter. Background Technology

[0002] A four-color printing press is a machine used for color printing. It uses four basic colors—cyan, magenta, yellow, and black (CMYK)—to create images of various colors by layering them. These four inks, mixed in specific proportions, can produce almost any color, making it suitable for the production of books, posters, packaging, and other color printed materials. Each printing unit on a four-color press is responsible for printing one basic color, and these colors are then layered to achieve a multi-color effect. Four-color printing ensures high color fidelity and high production efficiency, making it widely used in commercial printing.

[0003] Existing visual inspection methods for printed materials mainly rely on manual visual inspection. While this can guarantee quality to a certain extent, it also has significant drawbacks: manual inspection is easily affected by subjective factors such as fatigue and lack of experience, resulting in low inspection accuracy and being time-consuming and labor-intensive. Especially in high-speed printing processes, manual inspection is difficult to keep up with the production pace, easily leading to omissions or misjudgments, making it difficult to maintain stable printing quality. In addition, long-term repetitive manual inspection can easily cause fatigue, leading to low efficiency and increased production costs. Therefore, a visual inspection device for printed materials is proposed to solve the above problems. Utility Model Content

A visual inspection camera body is mounted at the center point of the lower end face of the positioning plate, and the visual inspection camera body is electrically connected to the controller.

[0009] As a further improvement of this utility model, one of the limiting plates is equipped with an mounting plate on its upper end face, and a sliding rod is equipped with a sliding block on the upper end face of the mounting plate. A connecting block is slidably provided on the outside of the sliding rod, and one side of the connecting block is connected to the positioning plate.

[0010] As a further improvement of this utility model, the lower end face of the positioning plate is equipped with two connecting plates and the two connecting plates are arranged in parallel, and two lighting lamps are installed between the lower ends of the two connecting plates.

[0022] The four-color printing machine body 1 is equipped with a detection table 2 on one side of the discharge end. Both sides of the upper surface of the detection table 2 are equipped with limit plates 21. One of the limit plates 21 is equipped with a housing 22 on one side. A display screen 23 is provided on one side of the housing 22. A controller 24 is provided inside the housing 22.

[0023] The upper surfaces of the two limit plates 21 are jointly equipped with a set of height adjustment components 3;

[0024] The height adjustment assembly 3 includes a motor mounting plate 30, on the upper surface of which a drive motor 31 is mounted. The output end of the drive motor 31 is connected to a threaded screw 32, which is vertically arranged. A sliding bushing 33 is externally engaged with the threaded screw 32. A slider 34 is mounted on the outside of the sliding bushing 33. A positioning plate 35 is mounted on one side of the slider 34. A vision inspection camera body 4 is mounted at the center point of the lower end face of the positioning plate 35, and the vision inspection camera body 4 is electrically connected to the controller 24.

[0025] In this embodiment, through the cooperation of the components within the height adjustment assembly 3, the drive motor 31 can be controlled to move the visual inspection camera body 4 back and forth within the stroke range of the threaded screw 32, thereby adjusting the height. This allows for flexible adjustment based on the size, thickness, or material of the printed material, adapting to various types of printed materials. Replacing manual inspection with the visual inspection camera body 4 significantly improves inspection accuracy. The visual inspection camera body 4 can accurately identify defects, color deviations, and pattern misalignments on printed materials, avoiding misjudgments caused by fatigue or subjective factors during manual inspection, ensuring the stability of inspection quality. The automated design of this device enables real-time inspection, greatly shortening inspection time, making it particularly suitable for high-speed printing operations. Automated inspection continuously follows the production rhythm without manual intervention, effectively improving overall production efficiency and avoiding production process delays caused by manual inspection. Automated inspection reduces reliance on manual labor, lowers the labor intensity and labor costs of inspection positions, and improves the standardization of inspection, making the production process smoother and output more stable, further reducing production costs.

[0026] In a further preferred embodiment, the electrical connection method is existing technology, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0027] Specifically, refer to Figure 1-3 One of the limiting plates 21 has an mounting plate 36 on its upper end face, and a sliding rod 37 is mounted on the upper end face of the mounting plate 36. A connecting block 38 is slidably provided on the outside of the sliding rod 37, and one side of the connecting block 38 is connected to the positioning plate 35.

[0028] In this embodiment, the sliding rod 37, together with the connecting block 38, is used to limit the positioning plate 35, making the positioning plate 35 more stable when moving.

[0029] Specifically, refer to Figure 1-3 The lower end face of the positioning plate 35 is equipped with two connecting plates 351, and the two connecting plates 351 are arranged in parallel. Two lighting lamps 352 are installed between the lower ends of the two connecting plates 351.

[0030] In this embodiment, when the printed material reaches the lower end of the visual inspection camera body 4, the two illumination lamps 352 can be turned on to provide a good light source, thereby maintaining the accuracy of the inspection.

[0031] Specifically, referring to Figure 1, the upper end face of the motor mounting plate 30 is equipped with two limit rods 301, and both limit rods 301 pass through the slider 34. The upper ends of the two limit rods 301 are jointly equipped with a top plate 302. The top plate 302 is provided with a bearing component, and the upper end of the threaded screw 32 is connected to the bearing component.

[0032] In this embodiment, the two limiting rods 301 are used to limit the slider 34, making the slider 34 more stable when it is driven to move. The top plate 302 is used to limit the slider 34 to prevent the slider 34 from exceeding the stroke range of the threaded screw 32.

[0033] The present invention relates to a visual inspection device for printed materials:

[0034] In actual use, the drive motor 31 is first connected to an external power source. By starting and controlling the drive motor 31, the drive motor 31 drives the threaded screw 32 connected to the output end to rotate. When the threaded screw 32 rotates, it drives the externally meshing sliding bushing 33 and the slider 34 installed on the outside of the sliding bushing 33 to move within the stroke range of the threaded screw 32. Finally, it drives the visual inspection camera body 4 to move, thereby adjusting the inspection height. When the printed matter reaches the lower end of the visual inspection camera body 4, the two lights 352 can be turned on to provide a good light source, thereby maintaining the inspection accuracy. When the visual inspection camera body 4 detects information, it feeds it back to the controller 24, so that the information is displayed on the display screen 23, which is convenient for staff to query and count.
