[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1-4 The present invention provides the following technical solution: A quality control and detection device for peptide-based special dietary foods includes: Framework 1; Shelf 2 is connected to the upper end of frame 1; Upper mounting bracket 5 is fixedly connected to the side end of upper frame 2; Conveyor belt 6, which is connected to the side end of the upper mounting frame 5; The detection device 13 is connected to the upper end of the upper frame 2 and is matched with the conveyor belt 6. The detection device 13 also includes a detection camera 1301 and a detection controller 1302. The detection camera 1301 is connected to the inner wall of the upper end of the detection device 13, and the detection controller 1302 is fixedly connected to the side end of the detection device 13. The sorting mechanism includes a fixed plate 14, a mounting base 20, a rotating rod 21, a T-shaped seat 22, a second cylinder 23, a gripper 25, and a driving component. The fixed plate 14 is connected to the side end of the detection device 13. The mounting base 20 is fixedly connected to the side end of the fixed plate 14. The rotating rod 21 is rotatably connected to the side end of the mounting base 20. The T-shaped seat 22 is fixedly connected to the circumferential surface of the rotating rod 21. The second cylinder 23 is fixedly connected to the side end of the T-shaped seat 22. The gripper 25 is fixedly connected to the output end of the second cylinder 23. The driving component is located on the side end of the fixed plate 14 to realize the rotation of the rotating rod 21.

[0018] In a specific embodiment of this utility model, when a polypeptide special dietary product needs to be tested for quality, the sample to be tested is first placed on the conveyor belt 6. The conveyor belt 6 starts to run under the drive of the motor, and drives the sample forward along the set path. In this way, it is ensured that the sample can enter the testing area stably and continuously, providing a basic guarantee for subsequent automatic testing and sorting operations.

[0019] When the sample passes under the detection device 13, the detection camera 1301 collects image data of the sample, and the detection controller 1302 processes and analyzes the collected information to identify key quality indicators such as the product's appearance integrity and component distribution. In this way, the system can quickly determine whether the sample is qualified and transmit the results to the main control system to provide a basis for decision-making for subsequent actions.

[0020] When the detection controller 1302 identifies a non-conforming sample, the control system immediately triggers the sorting mechanism to work, the drive component starts, the first cylinder 15 pushes the connecting plate 17 forward, causing the sliding toothed plate 19 to slide along the slide rail 16 and mesh with the gear 24, thereby driving the rotating rod 21 to rotate; in this way, the T-shaped seat 22 rotates with the rotating rod 21 to a preset angle, so that the gripper 25 is accurately aligned with the position of the non-conforming sample, ready to perform the gripping action.

[0021] When the second cylinder 23 is started, its output end pushes the gripper 25 downward to clamp the target sample; in this way, the defective products are accurately grasped, avoiding mis-clamping or missed clamping, and improving the efficiency and accuracy of the sorting process.

[0022] After the gripper 25 completes the gripping action, the rotating rod 21 rotates in the opposite direction to transfer the gripped product to the corresponding rejection area of ​​the loading platform 3 or unloading platform 4 for placement; in this way, the entire sorting process does not require manual intervention, which significantly improves the efficiency of detection and rejection, while reducing labor intensity.

[0023] When the next batch of products enters the testing area, the above process is automatically repeated; in this way, continuous and automated operation of quality control testing of peptide special dietary foods is realized, meeting the technical needs of modern food processing industry for high-precision testing and intelligent sorting.

[0024] Wherein: the detection camera 1301 is used to collect image information of the sample, and the detection controller 1302 is used to analyze and process the collected data to determine whether the sample meets the quality standards; the signal connection method between the detection camera 1301 and the detection controller 1302, and the communication connection method between the detection controller 1302 and the entire control system are conventional technical means in this field, so they will not be described in detail in this solution.

[0025] Please refer to the details. Figure 1-4 The driving components include a first cylinder 15, a connecting plate 17, a spring 18, a sliding toothed plate 19, a mounting base 20, and a gear 24. The first cylinder 15 is fixedly connected to the upper end of the fixed plate 14. The connecting plate 17 is connected to the output end of the first cylinder 15 by bolts and threads. The spring 18 is sleeved and connected to the circumferential surface of the output end of the first cylinder 15. The sliding toothed plate 19 is connected to the side end of the connecting plate 17. The mounting base 20 is fixedly connected to the side end of the rotating rod 21. The sliding toothed plate 19 matches the gear 24. The slide rail 16 is fixedly connected to the upper end of the fixed plate 14. The sliding toothed plate 19 and the slide rail 16 are slidably connected.

[0026] In this embodiment: when the control system issues a sorting command, the first cylinder 15 is activated, and its output end pushes the connecting plate 17 forward, causing the sliding toothed plate 19 to move along the slide rail 16; in this way, the sliding toothed plate is ensured to move forward smoothly and mesh accurately with the gear 24, thereby achieving stability and reliability of power transmission.

[0027] When the sliding toothed plate 19 meshes with the gear 24, the gear begins to rotate and drives the rotating rod 21 to rotate synchronously. The rotating rod is fixedly connected to the T-shaped seat 22 through the mounting base 20, thereby driving the gripper 25 to adjust to the target angle. In this way, the gripper can accurately align with the position of the defective product and complete the posture adjustment before gripping.

[0028] After the first cylinder 15 completes its pushing action, the spring 18 pushes the connecting plate 17 back under the action of elastic restoring force, causing the sliding toothed plate 19 to disengage from the gear meshing state, preparing for the next sorting action; in this way, not only is the working efficiency of the drive components improved, but mechanical wear is also effectively reduced and the service life of the equipment is extended.

[0029] In this way, when the slide rail 16 acts as a guide and limiter for the sliding toothed plate 19, the entire driving process runs smoothly and responds quickly; thus, in practical applications, it can better meet the technical requirements of the peptide special diet quality control and detection device for high-precision and high-frequency sorting operations.

[0030] Please refer to the details. Figure 1-4 The upper frame 2 is fixedly connected to a loading platform 3 on one side and a unloading platform 4 on the other side. The fixing plate 14 is connected to the unloading platform 4.

[0031] In this embodiment: when the polypeptide special dietary product needs to be tested for quality, the operator places the samples to be tested on the loading platform 3 in sequence, and the conveyor belt 6 starts to run under the drive of the motor, which smoothly transports the samples to the testing area; in this way, it is ensured that the samples can enter the testing process in an orderly and continuous manner, thereby improving the overall work efficiency.

[0032] After the inspection is completed, qualified products continue to move forward along conveyor belt 6 and are eventually transported to unloading platform 4 for collection; in this way, the automatic classification and orderly unloading of products are realized, reducing manual intervention and improving the automation level of the equipment.

[0033] After the gripper 25 removes unqualified products during the unloading process, these products are transferred to the corresponding rejection area on the loading platform 3 or unloading platform 4 to avoid affecting the subsequent normal process. In this way, the entire inspection line is ensured to operate smoothly, defective products are prevented from being mixed with qualified products, and the reliability of quality control is improved.

[0034] In this way, when the fixed plate 14 is connected to the unloading platform 4, the sorting mechanism can be stably installed near the unloading end, which facilitates the grabbing and transfer of unqualified products; thus, in practical applications, it can better meet the technical requirements of the polypeptide special diet quality control and testing device for efficient sorting and intelligent unloading.

[0035] Please refer to the details. Figure 1-4 A lower mounting frame 7 is fixedly connected to the side end of the frame 1, and a conveyor roller 8 is rotatably connected to the side end of the lower mounting frame 7. The conveyor roller 8 is matched with the conveyor belt 6.

[0036] In this embodiment: when the conveyor belt 6 starts running, its power is transmitted to the conveyor roller 8 on the lower mounting frame 7 through the transmission structure, so that the conveyor roller rotates synchronously with the conveyor belt; in this way, it is ensured that the conveyor belt is properly tensioned and runs smoothly during operation, avoiding deviation or slippage.

[0037] When the mounting frame 7 stably supports and fixes the conveyor roller 8 to the side of the frame 1, the conveyor belt 6 can smoothly rotate around the conveyor roller under the drive of the drive device; in this way, the structural stability and operational reliability of the entire conveying system are improved, and the testing process is guaranteed to be continuous.

[0038] When the conveyor belt carries the polypeptide special dietary product through the testing area, the conveyor roller 8 plays a guiding and supporting role, preventing the belt from sagging or shaking due to uneven load; this helps to improve the identification accuracy and sorting accuracy of the test device.

[0039] In this way, when the mounting frame 7 forms a stable connection with the conveyor roller 8 and is well matched with the conveyor belt 6, the entire conveying system has good load-bearing capacity and smooth operation; thus, in practical applications, it can better meet the technical requirements of the peptide special diet quality control and testing device for efficient and stable conveying.

[0040] Please refer to the details. Figure 1-4 A motor 10 is fixedly connected to the side end of the frame 1, and a second sprocket 11 is fixedly connected to the output end of the motor 10. A first sprocket 9 is fixedly connected to the side end of the conveying roller 8, and a chain 12 is rotatably connected to the circumferential surfaces of the first sprocket 9 and the second sprocket 11.

[0041] In this embodiment: when the motor 10 starts, its output end drives the fixedly connected second sprocket 11 to rotate. The second sprocket transmits power to the first sprocket 9, which rotates synchronously with the conveyor roller 8, through the chain 12. In this way, stable driving of the conveyor roller is achieved, ensuring that the conveyor belt 6 can run continuously and smoothly.

[0042] When the first sprocket 9 and the second sprocket 11 mesh with each other through the chain 12, the power of the motor is transmitted to the conveying system efficiently and with low noise, driving the entire conveying mechanism to work together. This not only improves the transmission efficiency of the equipment, but also enhances the stability and reliability during operation.

[0043] When the conveyor belt 6 starts to circulate under the drive of the chain drive system, the polypeptide special dietary samples can pass under the detection device 13 in sequence to realize continuous detection. In this way, the inefficiency caused by manual intervention is avoided, and the automation level and detection throughput of the whole detection device are improved.

[0044] In this way, when the transmission system consisting of motor 10, first sprocket 9, second sprocket 11 and chain 12 works together, the entire conveying process has good load adaptability and speed regulation performance; thus, in practical applications, it can better meet the technical requirements of stable transmission and efficient detection of peptide special dietary quality control and detection device.

[0045] Please refer to the details. Figure 1-4 The size of the loading platform 3 is equal to that of the unloading platform 4, and the upper frame 2 is connected to the frame 1 in a Z-shaped structure.

[0046] In this embodiment: when the loading platform 3 and the unloading platform 4 are designed to be exactly the same size, they are symmetrically arranged in terms of structural layout, which makes it convenient for operators to complete loading and unloading operations at the same working height; thus, the human-machine interaction of the equipment is improved and the labor intensity of manual handling is reduced.

[0047] When the upper frame 2 is connected to the frame 1 in a Z-shaped structure, the overall stress distribution is more reasonable, enhancing the stability and load-bearing capacity of the device. This not only optimizes the spatial layout but also improves the structural rigidity and vibration resistance of the equipment during operation.

[0048] When the lower loading platform 4 receives rejected unqualified samples or qualified products that have completed testing, its identical size design with the upper loading platform 3 makes the material flow smoother and facilitates connection with external conveying or collection devices; thus, it improves the automation level and operating efficiency of the entire testing line.

[0049] The specific connection structures and working principles of components such as the conveyor belt 6, conveyor roller 8, first sprocket 9, motor 10, second sprocket 11, chain 12, detection device 13, cylinder 15, cylinder 23, and gripper 25 involved in this solution are widely used in the field of food testing equipment and automation control technology. For example, the conveyor belt is supported by the conveyor roller and driven by the motor through sprocket and chain transmission; the detection device can use existing image recognition or component analysis technology to perform online detection of products; the cylinder and gripper cooperate to achieve automatic gripping action, and the related drive and control can be completed through a PLC system; the rotation and displacement control of the sorting mechanism is also based on mature mechanical transmission and pneumatic technology. The assembly relationship and collaborative control method between the above components are all conventional design methods for those skilled in the art, therefore, their specific structures and control logic will not be described in detail in this utility model. The focus of this utility model is on the integrated and optimized layout of each functional module and the automation improvement of the overall detection and sorting process, rather than the improvement of the working principle of individual components.

[0050] The working principle and usage process of this utility model are as follows: First, place the device on a stable workbench, confirm that the frame 1 is firmly supported and all components are properly connected, connect the power supply, start the control system, and perform self-checks on key components such as the motor 10, detection device 13, cylinders 15 and 23 to ensure normal operation; the operator places the polypeptide special dietary product to be tested onto the loading platform 3 in sequence, and the conveyor belt 6 starts running under the drive of the motor 10, driving the first sprocket 9 and the second sprocket 11 through the chain 12, so that the conveyor roller 8 rotates synchronously to achieve stable material transport; when the sample enters the detection area along the conveyor belt 6, the detection device 13 performs real-time identification and analysis of key indicators such as the product's component content and appearance integrity, and... The detection results are fed back to the control system; information on qualified and unqualified products is recorded separately and used for subsequent sorting decisions; when an unqualified product is detected, the control system triggers the sorting mechanism to operate: the first cylinder 15 pushes the sliding toothed plate 19 to mesh with the gear 24, driving the rotating rod 21 to rotate, thereby adjusting the angle of the T-shaped seat 22; then the second cylinder 23 starts, driving the gripper 25 to move downward and grab the unqualified product; after the gripper 25 completes the grabbing, the sorting mechanism resets, and the unqualified product is transferred to the corresponding rejection area of ​​the loading platform 3 or unloading platform 4, while qualified products continue to be transported along the conveyor belt to the unloading platform 4, where they are uniformly sorted by humans or external collection devices; the entire process can run continuously, achieving efficient detection and intelligent sorting of multiple batches of products.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
