Technical Field

[0001] This utility model relates to the field of quality inspection equipment technology, and in particular to a high-speed quality inspection device for soft label printed products. Background Technology

[0002] In the production of flexible printed products, such as flexible packaging and labels, printing quality inspection is a key step in ensuring product qualification rate.

[0003] In some traditional inspection equipment, printed materials are prone to curling, wrinkling, or shifting when transported at high speed, which affects the clarity of subsequent image acquisition and leads to missed or false detections. In order to solve the above problems, this utility model provides a high-speed inspection device for soft label printed products. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-speed quality inspection device for soft label printed products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-speed quality inspection device for soft label printed products includes an inspection box and an inspection mechanism. The inspection mechanism is fixedly connected to the middle of the upper surface of the inspection box. An inspection camera is fixedly connected to the upper end of the inner wall of the inspection box and is connected to the inspection mechanism. A feeding frame is fixedly connected to the front of the inspection box. An active roller is rotatably connected to the upper end of the inside of the feeding frame via a bearing. A driven roller is rotatably connected to the lower end of the inside of the feeding frame via a bearing. A support frame is fixedly connected to the lower end of the inspection box. An adsorption component is fixedly connected inside the support frame. A conveyor belt mechanism is provided inside the inspection box. A power component is fixedly connected to one side of the feeding frame.

[0007] As a further improvement of this utility model, the adsorption assembly includes a negative pressure fan fixedly connected inside the support frame, an mounting plate fixedly connected to the middle of the upper surface of the support frame, a negative pressure box fixedly connected to the middle of the lower surface of the mounting plate, a negative pressure pipe fixedly connected to the inlet end of the negative pressure fan, and the other end of the negative pressure pipe fixedly connected to the negative pressure box.

[0008] As a further improvement of this utility model, the power assembly includes a protective shell fixedly connected to one side of the feed frame. The upper end of the inside of the protective shell is rotatably connected to a drive gear via a bearing. The drive gear is connected to a drive roller. The lower end of the inside of the protective shell is rotatably connected to a driven gear via a bearing. The driven gear is connected to a driven roller. The drive gear and the driven gear mesh.

[0009] As a further improvement of this utility model, a first mounting groove is provided on the other side of the feeding frame, and a first servo motor is fixedly installed inside the first mounting groove. The power end of the first servo motor is fixedly connected to the other end of the drive roller.

[0010] As a further improvement of this utility model, a second mounting groove is provided on one side of the detection box, and a second servo motor is fixedly installed inside the second mounting groove. The power end of the second servo motor is fixedly connected to the conveyor belt mechanism, and several adsorption holes are provided in the middle of the surface of the conveyor belt mechanism.

[0011] As a further improvement of this utility model, supplementary lights are fixedly connected to both sides of the upper end of the inner wall of the detection box, directional indicators are fixedly connected to both sides of the detection box, and a discharge plate is fixedly connected to the back of the detection box.

[0012] The beneficial effects of this utility model are:

[0013] By incorporating a power unit, the device applies uniform pressure to the soft label printing products during the feeding stage through the upper and lower clamping structure of the active and driven rollers. This quickly eliminates the initial deformation of the printed products caused by curling, folding, or storage. The gear meshing transmission ensures that the two rollers rotate synchronously, avoiding stretching or wrinkling caused by speed differences. This allows the printed products to enter the inspection area in a flat state, shortening the production preparation time and providing a stable foundation for subsequent high-speed inspection, thus reducing the risk of false detection caused by surface unevenness.

[0014] By setting up an adsorption component, during use, the adsorption holes on the surface of the conveyor belt mechanism continuously adsorb the printed materials through a negative pressure fan, further eliminating minor fluctuations or edge warping during high-speed movement. The combination of negative pressure adsorption and rigid support of the conveyor belt ensures that the printed materials are in full contact with the conveyor surface throughout the inspection chamber, avoiding image blurring caused by airflow or mechanical vibration. This allows the device to improve image acquisition clarity while maintaining high inspection speed, ensuring the reliability of defect identification. Attached Figure Description
