Description

Technical Field

[0001] This utility model relates to the field of printing inspection technology, specifically to a high-speed online printing quality inspection device. Background Technology

[0002] In the modern printing industry, with the continuous increase in production speed, the demand for printing quality inspection is becoming increasingly urgent. Traditional printing quality inspection methods mostly rely on manual sampling, which is not only inefficient and unable to meet the production pace of high-speed printing, but also greatly affected by human factors, making the inspection results prone to errors and omissions.

[0003] While some existing online inspection equipment has improved inspection efficiency to some extent, it still has many shortcomings. Some equipment lacks sufficient inspection accuracy and cannot accurately identify minute printing defects; some equipment has poor adaptability and can only inspect specific types of printed materials or printing processes; and some equipment lacks an effective marking and processing mechanism after detecting defective products, which is not conducive to subsequent sorting and repair work.

[0004] Therefore, those skilled in the art have provided a high-speed online printing quality inspection device to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides:

[0006] A high-speed online printing quality inspection device includes: a printing inspection table; and printed materials to be inspected are placed on the printing inspection table.

[0007] Furthermore, the printing inspection station is detachably equipped with a printing image inspection structure for image inspection of printed materials in the middle section;

[0008] The printed image detection structure includes a detection box frame, and an inner detection box is fixedly installed inside the detection box frame. A defective product printing cotton for marking defective printed products is installed between the inner detection box and the detection box frame.

[0009] Preferably, the top of the defective printed cotton is equipped with a lifting frame that is movably disposed between the inner detection box and the detection box frame.

[0010] Preferably, synchronous electric lifting rods are installed at each of the four corners of the lifting frame and between the lifting frame and the detection box frame.

[0011] Preferably, the outer walls on both sides of the detection box frame are fixedly equipped with a support top frame, and the bottom wall of the support top frame is equipped with an electric linear telescopic cylinder.

[0012] Preferably, the bottom end of the electric linear telescopic cylinder is equipped with an assembly side frame that can be detachably mounted on the printing inspection table.

[0013] Preferably, the top of the inner detection box is equipped with an image detector for capturing images of printed materials, and the inner edge of the inner detection box is equipped with a flat lamp for supplementing illumination of the printed materials.

[0014] Preferably, the defective printed cotton is connected to a pigment tube, the end of which, away from the defective printed cotton, extends through the outside of the inspection box frame and is connected to a pigment pump. The extraction end of the pigment pump is connected to a pigment box fixedly installed on the outer wall of the inspection box frame.

[0015] A transmission roller 1 is rotatably mounted on the inner side of one end of the printing inspection table, and a transmission roller 2 is rotatably mounted on the other end of the printing inspection table. A pulley 1 is fixedly mounted on the outer side of one end of the transmission roller 1, and a belt is wound around the outer side of the pulley 1.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention comprises a marking system consisting of defective printing cotton, a pigment tube, a pigment pump, and a pigment box. Once a defective product is detected by the image detector, the pigment pump quickly draws pigment from the pigment box and delivers it to the defective printing cotton via the pigment tube, making a clear mark on the defective product. This facilitates subsequent sorting and processing, prevents defective products from being mixed with qualified products, and improves product sorting efficiency and accuracy.

[0019] This invention utilizes an image detector on the top of the inner box and a flat light along the inner edge to work in conjunction. The flat light provides uniform illumination, reducing glare and shadow interference on the printed surface, allowing the image detector to clearly capture image details and accurately identify minor defects such as color deviation, pattern blurring, registration errors, and missing prints, ensuring high-quality detection accuracy.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The examples of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0030] For examples, please refer to Figures 1-5 This embodiment provides a high-speed online printing quality inspection device, including: a printing inspection table 1; a printed matter 3 to be inspected is disposed on the printing inspection table 1; and a printing image inspection structure 2 for image inspection of the printed matter 3 is detachably installed in the middle of the printing inspection table 1; the printing image inspection structure 2 includes an inspection box frame 201, and an inspection inner box 205 is fixedly disposed inside the inspection box frame 201; a defective product printing cotton 210 for marking defective products printed on the printed matter 3 is disposed between the inspection inner box 205 and the inspection box frame 201; and a lifting frame 209 is movably disposed between the inspection inner box 205 and the inspection box frame 201 on the top of the defective product printing cotton 210.

[0031] Synchronous electric lifting rods 208 are installed at each of the four corners of the lifting frame 209 and between it and the detection box frame 201; support top frames 203 are fixedly installed on both outer walls of the detection box frame 201, and electric linear telescopic cylinders 204 are installed on the bottom wall of the support top frames 203; the bottom end of the electric linear telescopic cylinders 204 is equipped with an assembly side frame 202 that can be detachably installed on the printing detection table 1; the top of the detection inner box 205 is equipped with an image detector 206 for image capture of the printed matter 3, and a flat lamp 207 for supplemental lighting of the printed matter 3 is installed on the inner edge of the detection inner box 205.

[0032] The defective printed cotton 210 is connected to a pigment tube 211. One end of the pigment tube 211 away from the defective printed cotton 210 passes through the outside of the inspection box frame 201 and is connected to a pigment pump 212. The extraction end of the pigment pump 212 is connected to a pigment box 213 fixedly installed on the outer wall of the inspection box frame 201. A transmission roller 4 is rotatably installed on the inner side of one end of the printing inspection table 1, and a transmission roller 8 is rotatably installed on the other end of the printing inspection table 1. A pulley 5 is fixedly mounted on the outer side of one end of the transmission roller 4, and a belt 6 is wound around the outer side of the pulley 5. A pulley 7 fixedly mounted on the outer side of the inner side of the belt 6 away from the pulley 5 is wound around the inner side of the belt 6. A servo motor 9 is fixedly installed on the printing inspection table 1 at one end of the transmission roller 4, and a controller 10 is installed on the outer wall of the printing inspection table 1.

[0033] According to the above embodiments, the working principle of this utility model is as follows:

[0034] Printed material 3 is transferred: Servo motor 9 starts and drives transmission roller 4 to rotate; Since pulley 5 on transmission roller 4 is connected to pulley 7 through belt 6, transmission roller 8 will rotate synchronously with transmission roller 4; Under the action of transmission roller 4 and transmission roller 8, printed material 3 is transferred smoothly and continuously on printing inspection table 1, so that printed material 3 can continuously enter the inspection area to be inspected.

[0035] Image detection and illumination: When the printed matter 3 moves under the printing image detection structure 2, the image detector 206 on the top of the inner box 205 starts to work and takes an image of the printed matter 3; at the same time, the flat light 207 on the inner edge of the inner box 205 lights up to provide uniform illumination for the printed matter 3, ensuring that the image detector 206 can take a clear and accurate image of the printed matter 3, so as to analyze and judge the quality of the printed matter 3 in the future.

[0036] Defective Product Marking: The image detector 206 transmits the captured image information to the controller 10, which analyzes and processes the image. When a defective product is detected in the printed matter 3, the controller 10 issues a command to control the synchronous electric lifting rod 208 to operate. The synchronous electric lifting rod 208 drives the lifting frame 209 to descend, thereby causing the defective printing cotton 210 connected to the lifting frame 209 to descend and contact the printed matter 3. At the same time, the pigment pump 212 starts, drawing pigment from the pigment box 213 through the pigment tube 211 and delivering it to the defective printing cotton 210, marking the defective product for subsequent identification and processing.

[0037] Detection structure adjustment: If it is necessary to adjust the height or position of the printing image detection structure 2, it can be achieved by the electric linear telescopic cylinder 204; the electric linear telescopic cylinder 204 works to push the assembly side frame 202 to move up and down, thereby driving the entire printing image detection structure 2 to rise or fall, so as to adapt to the detection of printed matter 3 with different thicknesses or different detection requirements.

[0038] The image detector 206 is connected to the controller 10, and the controller 10 is connected to an IoT cloud, which can identify the image printed matter 3 entered by the image detector 206 online.
