Technical Field

[0001] The utility model relates to the technical field of printing quality detection, in particular to a newspaper printing quality detection device. Background Technique

[0002] Newspaper printing refers to the printing process with newspapers and other information media as products, involving a series of steps such as typesetting, page makeup, plate making, printing, etc. Traditionally, letterpress printing technology was mainly used for newspaper printing. However, with the development of technology, offset rotary printing has become the mainstream method for newspaper printing due to its advantages such as strong adaptability, good quality, low cost, and high efficiency. A newspaper printing quality detection device is a mechanical device specifically designed to evaluate and monitor the printing quality of newspapers and other printed materials. This device can automatically detect multiple quality indicators of printed materials, such as color accuracy, image clarity, integrity, etc., and can timely detect potential printing defects.

[0003] Currently, during the use of existing newspaper printing quality detection devices, most of them use high-speed digital cameras to capture images of printed materials and analyze the images through image processing algorithms to evaluate the printing quality. Most of the existing high-speed digital cameras are installed and fixed at the use position by means such as bolts. When disassembling and assembling the high-speed digital camera, it is rather cumbersome, which easily reduces the disassembly and assembly efficiency of the high-speed digital camera. To solve this technical problem, the utility model proposes a newspaper printing quality detection device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a newspaper printing quality detection device, which can effectively solve the problems mentioned in the background technique.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a newspaper printing quality detection device;

[0023] It includes a support table 1, a conveyor belt 4 and a mounting plate 7. A clamping shell 8 is provided at the bottom end of the mounting plate 7, a clamping block 9 is provided at the bottom end of the clamping shell 8, a first support frame 11 is provided at the top end of the mounting plate 7, a first pull rod 12 is penetrated through the inside of the first support frame 11, a second pull rod 13 is provided at the bottom end of the first pull rod 12, and the second pull rod 13 is movably inserted into the inside of the clamping block 9. A spring 14 is provided at the top end of the second pull rod 13, and the top end of the spring 14 is connected to the inner wall of the top of the first support frame 11. A camera body 10 is provided at the bottom end of the clamping block 9, and the camera body 10 is located above the conveyor belt 4. A handle 15 is provided at the top end of the first pull rod 12, and the handle 15 is located at the top of the mounting plate 7.

[0024] The clamping shell 8 is arranged at the bottom end of the mounting plate 7, and the clamping block 9 is fitted, movably detachable and assembled with the clamping shell 8, which facilitates the disassembly and assembly of the clamping block 9 from the inside of the clamping shell 8. The first support frame 11 is arranged at the top end of the mounting plate 7, and the first pull rod 12 movably penetrates through the inside of the first support frame 11. The first support frame 11 can limit the up and down movement of the first pull rod 12. The diameter of the first pull rod 12 is smaller than that of the second pull rod 13. When installing, first push the second pull rod 13 towards the first pull rod 12 by hand. At this time, the spring 14 is compressed, causing the handle 15 to move upward accordingly. Then, place the clamping block 9 into the clamping shell 8 for clamping. After clamping, release the thrust on the second pull rod 13, and the spring 14 moves into the inside of the clamping block 9 due to the elastic force of rebound. At this time, the spring 14 is compressed, so as to complete the fixation of the other side of the clamping block 9. Similarly, when it is necessary to detect and repair the camera body 10 at the bottom end of the clamping block 9, by applying a pulling force to the handle 15 at the top end of the first pull rod 12, the first pull rod 12 drives the second pull rod 13 to be pulled out from the inside of the clamping block 9, deforming the spring 14 by extrusion, and the limit of the second pull rod 13 on the clamping block 9 can be released. The structure is simple and practical, effectively improving the disassembly and assembly efficiency of the camera body 10.

[0026] A first motor 2 is arranged on the front surface of the support table 1. Two groups of rollers 3 are rotatably arranged inside the support table 1, and one end of one group of the rollers 3 is connected to the output end of the first motor 2. A conveyor belt 4 is movably arranged on one side of the rollers 3, and the conveyor belt 4 is located inside the support table 1. Two groups of support plates 5 are arranged at the top end of the support table 1. An electric push rod 6 is arranged on the front surface of the support plate 5, and the output end of the electric push rod 6 is connected to the bottom end of the mounting plate 7. The mounting plate 7 is located above the support plate 5.

[0027] There are two sets of support platforms 1. The support platform 1 is the main support component of the newspaper printing quality detection device. Two sets of rollers 3 are rotatably arranged inside the support platform 1, and the conveyor belt 4 is arranged outside the two sets of rollers 3. When the first motor 2 operates, one set of rollers 3 can rotate inside the support platform 1. By the connection of the conveyor belt 4, the conveyor belt 4 drives the other set of rollers 3 to rotate inside the support platform 1, so that the conveyor belt 4 rotates in a cycle inside the support platform 1 to convey and move the newspaper, passing under the camera body 10. The support plate 5 is used to provide installation support for the electric push rod 6. The output end of the electric push rod 6 is connected to the bottom end of the mounting plate 7, and the mounting plate 7 is movably located above the support plate 5. When the electric push rod 6 operates, it is convenient to adjust the use height of the mounting plate 7 according to the use requirements. The camera body 10 is a high-speed digital camera. The camera body 10 is signal-connected to an external monitoring and display device. The camera body 10 takes pictures of the newspaper conveyed on the top of the conveyor belt 4 and analyzes the images through an image processing algorithm to evaluate the quality of newspaper printing.
