Description

Technical Field

[0001] This utility model relates to the field of konjac flour production, specifically to a foreign object detection device on a konjac flour production line. Background Technology

[0002] In the production of konjac flour products, ensuring the safety and quality of the final product is paramount. However, in practice, after konjac flour is filled into packaging bags, it is often randomly piled up on the conveyor belt. This leads to several major problems: due to the irregular stacking of materials, the packaging bags may pile up or fold, making it difficult to accurately detect any foreign objects inside. Traditional detection methods are inefficient and inaccurate under these circumstances. Once foreign objects are detected during the inspection process, the entire production line usually needs to be stopped for handling. This situation not only increases production uncertainty but also significantly reduces overall production efficiency, resulting in economic losses. Utility Model Content

[0003] The main objective of this invention is to provide a foreign object detection device for konjac flour production lines, thereby solving the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes a first conveying mechanism, and two independently operating second conveying mechanisms are provided in parallel below the end of the first conveying mechanism, and each of the second conveying mechanisms is provided with an X-ray detection device;

[0005] A partition plate is provided between the two second conveying mechanisms. A rotating guide plate is provided on the partition plate. The guide plate rotates on the first conveying mechanism to divert the material on the first conveying mechanism.

[0006] A paving device is provided between the partition plate and the second conveying mechanism. The paving device is located at the front end of the X-ray detection device and is used to flatten the material on the second conveying mechanism.

[0007] Preferably, a swing cylinder is fixed on the partition plate, and the end of the guide plate is fixed on the rotating shaft of the swing cylinder;

[0008] The swing cylinder drives the guide plate to be centered in the middle of the first conveying mechanism, or against the left or right wall of the first conveying mechanism.

[0009] Preferably, the X-ray detection device covers the second conveying mechanism. The X-ray detection device includes an X-ray generator and a linear array sensor. The X-ray generator is located above the second conveying mechanism, and the linear array sensor is located inside the second conveying mechanism. The X-ray generator is directly opposite the linear array sensor.

[0010] The material conveyed on the second conveying mechanism moves between the X-ray generator and the linear array sensor.

[0011] Preferably, pressure rollers are provided on the outer sides of both ends of the mandrel in the paving device, and the pressure rollers are located on the second conveying mechanism;

[0012] The middle part of the spindle is connected to the partition plate through the first bearing seat, and both ends are connected to the outer wall of the second conveying mechanism through the second bearing seats.

[0013] Preferably, the two ends of the first bearing housing are connected to the partition plate through the first guide post, the bottom of the first guide post is fixed on the partition plate, the two ends of the first bearing housing slide against the first guide post through the sliding sleeve, the top of the first guide post is fixedly provided with a fixed seat, the middle of the fixed seat is provided with a threaded screw, and the end of the screw abuts against the first bearing housing and rotates.

[0014] Preferably, a threaded sleeve is fixed in the middle of the fixed seat, the threaded sleeve is threadedly connected to the lead screw, a handwheel is fixed at the top of the lead screw, and the bottom of the lead screw is rotated by a bearing on the first bearing seat.

[0016] This utility model provides a foreign object detection device for konjac flour production lines, with the following advantages:

[0017] 1. By introducing a paving device, especially its pressure roller design, the packaging bags can be flattened and spread out, effectively avoiding the accumulation or folding of the bags. This makes the material more even when entering the X-ray inspection device, thereby improving the accuracy and clarity of foreign object detection. The combined use of the X-ray generator and linear array sensor ensures efficient scanning and imaging of the internal structure of the material, further improving the accuracy of foreign object detection.

[0018] 2. The two independently operating secondary conveying mechanisms allow the other to continue operating even if one needs to stop due to foreign object detection, preventing interruptions to the entire production line and greatly improving production continuity and stability. The oscillating cylinder drives the guide plate to adjust the material flow direction according to actual conditions, ensuring smooth production even under abnormal circumstances.

[0019] 3. The height of the first bearing seat, mandrel, and pressure roller is adjusted by turning the screw with a handwheel, allowing the device to adapt to packaging bags of different sizes, increasing the equipment's versatility and practicality. The system can react quickly upon detecting foreign objects, guiding the material to the normally operating conveyor mechanism by adjusting the guide plate position, reducing troubleshooting time.

[0020] 4. The X-ray detection device covers the second conveying mechanism to form a closed detection area, preventing X-ray leakage and ensuring the safety of operators. The entire detection and diversion process is highly automated, reducing reliance on manual operation and lowering the risk of human error.

[0021] 5. By reducing downtime and shortening troubleshooting time, overall production efficiency has been improved and production costs have been reduced. Efficient foreign object detection and precise quality control measures help improve the quality of the final product and enhance market competitiveness. Attached Figure Description

Detailed Implementation

[0029] like Figures 1-5 As shown, a foreign object detection device on a konjac flour production line includes a first conveying mechanism 1, and two independently operating second conveying mechanisms 2 are arranged in parallel below the end of the first conveying mechanism 1. Each of the second conveying mechanisms 2 is equipped with an X-ray detection device 3.

[0030] A partition plate 6 is provided between the two second conveying mechanisms 2. A rotating guide plate 5 is provided on the partition plate 6. The guide plate 5 is located on the first conveying mechanism 1 and rotates to divert the material on the first conveying mechanism 1.

[0031] A spreading device 4 is provided between the partition plate 6 and the second conveying mechanism 2. The spreading device 4 is located at the front end of the X-ray detection device 3 and is used to spread the material on the second conveying mechanism 2.

[0032] After the konjac flour product is packaged, it moves on the first conveyor 1. The flow is diverted by the guide plate 5 so that the konjac flour product falls onto the second conveyor 2 below. The spreading device 4 flattens the konjac flour product, so that it enters the X-ray detection device 3 for foreign object detection, thereby improving the detection efficiency. When one of the second conveyor 2 detects foreign objects and stops, it does not affect the normal operation of the other second conveyor 2, thus avoiding the overall shutdown and affecting production efficiency.

[0033] This design not only improves the efficiency of foreign object detection, but also ensures that even if one channel malfunctions and requires a shutdown for inspection, the other channel can continue production, greatly improving the stability and efficiency of the production line.

[0034] Preferably, a swing cylinder 7 is fixed on the partition plate 6, and the end of the guide plate 5 is fixed on the rotating shaft of the swing cylinder 7;

[0035] The swing cylinder 7 drives the guide plate 5 to be centered in the middle of the first conveying mechanism 1, or to abut against the left or right wall of the first conveying mechanism 1.

[0036] When the guide plate 5 is located in the middle of the first conveying mechanism 1, the material on the first conveying mechanism 1 can fall into the two second conveying mechanisms 2 and move. When the material on one of the second conveying mechanisms 2 is detected to have a foreign object and stops, the swing cylinder 7 drives the guide plate 5 to rotate so that the material on the first conveying mechanism 1 falls into the normally operating second conveying mechanism 2 for inspection.

[0037] The dual-channel design ensures that even if one channel fails and stops, the other channel can continue operating, reducing overall production line downtime. The design of the oscillating cylinder and guide vanes allows for rapid adjustment of material flow according to actual needs, adapting to different production conditions.

[0038] Preferably, the X-ray detection device 3 covers the second conveying mechanism 2. The X-ray detection device 3 includes an X-ray generator 301 and a linear array sensor 302. The X-ray generator 301 is located above the second conveying mechanism 2, and the linear array sensor 302 is located inside the second conveying mechanism 2. The X-ray generator 301 is directly opposite the linear array sensor 302.

[0039] The material conveyed on the second conveying mechanism 2 moves between the X-ray generator 301 and the linear array sensor 302.

[0040] The X-ray generator 301 and the linear array sensor 302 work together to quickly generate high-definition images of the material's interior, enabling accurate detection of foreign objects. The detection device features a closed design to effectively prevent X-ray leakage and ensure operator safety. This device is suitable for konjac flour products of various shapes and materials, including bagged, boxed, or other packaged products. Compared to traditional area array sensors, the linear array sensor offers higher resolution and faster scanning speed, making it suitable for continuous production scenarios. It can scan the material line by line, generating complete internal images in real time, thus improving detection efficiency.

[0041] Preferably, pressure rollers 408 are provided on the outer sides of both ends of the mandrel 405 in the paving device 4, and the pressure rollers 408 are located on the second conveying mechanism 2;

[0042] The middle part of the spindle 405 is connected to the partition plate 6 through the first bearing seat 404, and both ends are connected to the outer wall of the second conveying mechanism 2 through the second bearing seat 407.

[0043] The gap between the pressure roller 408 and the second conveying mechanism 2 can flatten and spread out the plastic packaging bag of konjac products, avoiding the accumulation of the packaging bag, so that it can be scanned more clearly in the X-ray detection device 3.

[0044] The first bearing seat 404 is connected to the partition plate 6 at both ends through the first guide post 401. The bottom of the first guide post 401 is fixed on the partition plate 6. The two ends of the first bearing seat 404 slide against the first guide post 401 through the sliding sleeve. The top of the first guide post 401 is fixedly provided with a fixed seat 402. The middle part of the fixed seat 402 is provided with a threaded screw 403. The end of the screw 403 abuts against the first bearing seat 404 and rotates.

[0045] A threaded sleeve is fixed in the middle of the fixed seat 402. The threaded sleeve is threadedly connected to the lead screw 403. A handwheel is fixed at the top of the lead screw 403. The bottom of the lead screw 403 is rotated by a bearing on the first bearing seat 404.

[0046] The two ends of the second bearing seat 407 are connected to the outer wall of the second conveying mechanism 2 through the second guide post 406. The bottom of the second guide post 406 is fixed on the second conveying mechanism 2, and the two ends of the second bearing seat 407 slide against the second guide post 406 through the sliding sleeve.

[0047] By rotating the drive handwheel, the lead screw 403 can be rotated, which in turn drives the first bearing seat 404 to move up and down, thereby moving the spindle 405 and the pressure roller 408, thus adjusting the height of the distance from the second conveying mechanism 2, which is suitable for packaging konjac products of different sizes.

[0048] Depending on the packaging size of the konjac flour product to be processed, the operator first needs to adjust the height of the pressure roller 408 from the second conveying mechanism 2. This is achieved by turning the handwheel, causing the lead screw 403 to drive the first bearing seat 404 to move up and down along the first guide column 401, thereby adjusting the height of the mandrel 405 and the pressure roller 408. The konjac flour product is conveyed forward through the second conveying mechanism 2. When the material reaches below the pressure roller, the pressure roller flattens and spreads out its plastic packaging bag, preventing the packaging bag from piling up or folding, allowing the material to enter the X-ray inspection device 3 flat for scanning. During the production process, if it is necessary to process packaging of different sizes, the height of the pressure roller can be quickly adjusted by simply turning the handwheel to ensure the best spreading effect and inspection accuracy.

[0049] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
