Abstract
Description
Technical Field
[0001] This utility model relates to the field of roasted product production technology, specifically to an automatic crack detection and sorting device for roasted products. Background Technology
[0002] Cracks are one of the most common defects in the production of roasted products. Their causes are complex and varied, potentially stemming from multiple factors such as raw material ratios, molding pressure, roasting curve control, or cooling processes. As basic industrial materials or products directly supplied to end users, surface or internal cracks in roasted products can severely weaken their mechanical strength, durability, and safety performance, directly impacting the final product's usability and lifespan. Therefore, crack detection in roasted products is an indispensable and crucial step in production quality control. It aims to ensure that products leaving the factory meet stringent quality standards, maintain the company's brand reputation, and prevent defective products from reaching downstream customers, causing greater economic losses or safety hazards.
[0003] However, current methods for detecting cracks in roasted products still largely rely on traditional manual visual inspection. This approach is not only inefficient and ill-suited to the pace of modern high-speed production lines, but also highly susceptible to missed or incorrect detections due to operator fatigue, experience differences, and subjective judgment, making it impossible to guarantee the stability and consistency of the test results. Although some companies have attempted to introduce basic automated inspection devices, these devices are prone to damaging roasted products during sorting. Therefore, we propose an automated crack detection and sorting system for roasted products. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an automatic detection and sorting equipment for cracks in roasted products. It can achieve efficient, accurate and non-destructive automated detection and sorting, effectively improve the level of product quality control, and significantly reduce the risk of human error and secondary damage in the production process. It can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic detection and sorting device for cracks in roasted products, including a support frame and detection components; Support frame: A second mounting frame is fixed on the upper side, and a second belt conveyor is installed inside the second mounting frame. A connecting frame is fixed on the right side of the second mounting frame, and a conveying component and a sorting component are installed inside the connecting frame. A height adjustment component is installed on the upper side of the support frame, and the upper end of the height adjustment component is connected to the sorting component. Classification conveying components are installed at the front and rear ends of the upper side of the connecting frame. The input end of the second belt conveyor is electrically connected to the output end of an external PLC controller. The detection component includes an L-shaped blocking frame, an industrial camera, and a detection light source. The L-shaped blocking frame is fixed to the upper right end of the connecting frame. The industrial camera and the detection light source are installed on the upper side inside the L-shaped blocking frame. The industrial camera is bidirectionally electrically connected to an external PLC controller. The input end of the detection light source is electrically connected to the output end of the external PLC controller. The detection component is used to detect cracks on the surface of the roasted product.
[0006] Furthermore, the conveying assembly includes a first mounting frame, a first motor, conveying rollers, sprocket rings, and a chain. The first mounting frame is fixed to the left end of the front side of the connecting frame, and the first motor is installed inside the first mounting frame. The front and rear ends of the connecting frame are provided with evenly distributed rotating holes. The connecting frame is provided with four corresponding conveying rollers, and the front and rear ends of the four conveying rollers are respectively rotatably connected to the interior of their corresponding rotating holes. A sprocket ring is fixed to the rear end of the surface of the left and right conveying rollers, and two corresponding sprocket rings are fixed to the rear end of the surface of the two middle conveying rollers.

By setting the conveying assembly, the roasted product is conveyed to the bottom of the L-shaped blocking frame.
[0007] Furthermore, the sorting assembly includes a mounting frame, rotating rings, conveyor belts, a second mounting bracket, a second motor, a fixed frame, and pressure sensors. The connecting frame contains three corresponding mounting frames located between four conveyor rollers. Four corresponding rotating rings are rotatably connected within each mounting frame, and these rings are connected by the conveyor belt. A second mounting bracket is fixed to the side of each mounting frame, and a second motor is installed inside the second mounting bracket. The output shaft of the second motor is fixed to the end face of the corresponding rotating ring. Fixed frames are fixed to the sides of the three mounting frames. Two corresponding pressure sensors are installed on the lower side of the connecting frame, each corresponding to a fixed frame. The pressure sensors are bidirectionally electrically connected to an external PLC controller. The input terminal of the second motor is electrically connected to the output terminal of the external PLC controller. By configuring the sorting assembly, if the roasted product has cracks, all the second motors will rotate forward, driving the three conveyor belts to rotate backward, transporting the cracked product to the rear first belt conveyor. Conversely, if the roasted product has no cracks, all the second motors will rotate in reverse, transporting the uncracked roasted product to the front first belt conveyor.
[0008] Furthermore, the height adjustment component includes a hydraulic rod and a connecting seat. The hydraulic rod is installed on the upper right end of the bracket, and the connecting seat is fixed on the telescopic arm of the hydraulic rod.

[0015] The working principle of the automatic crack detection and sorting equipment for roasted products provided by this utility model is as follows: During use, the second belt conveyor 8 is responsible for initially conveying the roasted products to the area of the connecting frame 9.

The detection light source 23 in the detection component 2 provides uniform illumination. The industrial camera 22 captures the surface image of the roasted products and transmits the data to the external PLC controller for analysis to identify crack defects. After the detection is completed, the hydraulic rod 51 of the height adjustment component 5 adjusts the sorting component through the connecting seat 52. The height of the mounting frame 41 is raised to support the roasted product. The pressure sensor 47 monitors the position of the fixed frame 46 to ensure stability. According to the instructions of the PLC controller, the second motor 45 drives the rotating ring 42 and the conveyor belt 43 to rotate. If there is a crack, all the second motors 45 rotate forward, driving the conveyor belt 43 to move backward, and transporting the defective roasted product to the rear classification conveyor component 6. If there is no crack, the second motor 45 reverses and transports the qualified product to the front classification conveyor component 6. In the classification conveyor component 6, the first belt conveyor 62 transports the roasted product to the corresponding area according to the sorting result, completing the automatic sorting process. Throughout the process, all components are coordinated and controlled by the PLC controller to ensure efficient and accurate detection and sorting.
