Description

Technical Field

[0001] This invention relates to the technical field of pretreatment devices for testing clean vegetables, and specifically to a pretreatment device for testing clean vegetables. Background Technology

[0002] With the rapid development of the ready-to-eat pre-packaged vegetable industry, the market is increasingly demanding zero-damage and zero-rot delivery standards for root vegetables (such as potatoes, carrots, radishes, and yams). Traditional pre-packaged vegetable production lines are highly susceptible to mechanical damage such as skin bruising during harvesting, storage, transportation, and loading / unloading. This damage is initially difficult to detect with the naked eye, but can induce browning, soft rot, and even pathogen invasion after a period of time, leading to the scrapping of the entire batch of vacuum-packed products. Current technologies generally employ the following two methods: Visual sorting: RGB or near-infrared cameras are placed on the conveyor line to identify defective areas by differences in color and texture. However, minor bruises and deep punctures show very little difference in grayscale in two-dimensional images, resulting in a high misjudgment rate; moreover, it is impossible to know whether rot has spread to the inside of the fruit, so the whole fruit must be removed, resulting in waste of edible parts.

[0003] Sampling and dissection testing: Vegetables are cut into sections manually or by a robotic arm and then sent for rapid microbial testing or pH / conductivity measurement. This method is destructive sampling, resulting in insufficient sample size and difficulty in covering hidden damage; at the same time, the dissection location is random and cannot be aimed at lesions, often leading to missed detections.

[0004] In recent years, some studies have attempted to introduce "online visual positioning + pinpoint cutting" into the pretreatment of clean vegetables, but existing devices have the following common drawbacks: 1. The fixed angle of the cutting blade makes it impossible to adjust the cutting depth and angle according to the epidermal injury or deep piercing injury, resulting in overcutting or incomplete removal; 2. The resection and sampling actions are separated, requiring an additional robotic arm to complete the sampling, which is redundant and results in a large deviation between the sample position and the lesion coordinates; 3. The lack of a synchronous reverse sampling mechanism makes it impossible to guarantee "sampling only where needed," resulting in insufficient representativeness of the test results; 4. The sampling tube is a single-point type, which cannot complete circumferential multi-layer insertion in one rotation, resulting in a small sample volume and inaccurate pathogen detection.

[0005] Therefore, we propose a pretreatment device for the detection of pre-cleaned vegetables. Summary of the Invention

The crankshaft 88 is fixedly connected to the top wall of the separator box 85. Multiple push rods 813 are rotatably connected to the side wall of the crankshaft 88.

[0031] The inner wall of the convex block 5 has a cavity 91, and multiple electric push rods 92 are installed on the inner wall of the cavity 91. Multiple push plates 93 are slidably connected through the inner wall of the convex block 5. One end of the push plate 93 is fixedly connected to the adjacent electric push rod 92, and the other end of the push plate 93 is fixedly connected to the movable frame 10.

[0032] An automatic pickup device 16, such as a robotic arm, is installed on the side wall of the conveyor roller 1. A vision camera 17 is installed on the automatic pickup device 16. The vision camera 17 has a built-in lightweight model and outputs damage category signals including three categories: "normal", "superficial dent", and "deep puncture". The vision camera 17 is connected to the automatic pickup device 16, motor 18, electric push rod 4 and other structures through a controller.

[0033] A sampling plate 816 is detachably installed on the convex block 5, and the sampling plate 816 is located directly below the discharge pipe 89.

[0034] In this invention, root vegetables that have undergone washing and other processes during the initial preparation of clean vegetables are placed on conveyor roller 1 and conveyed to the next process by conveyor roller 1.

[0035] During the conveying process, the automatic pickup device 16 drives the vision camera 17 to visually monitor the root vegetables that are rolling on the conveyor roller 1. If there are any root vegetables with surface damage caused during storage or transportation, the vision camera 17 will pick them up and place them on the processing table 2 through the automatic pickup device 16, with the damaged part of the root vegetable facing upwards, and determine the extent of the damage (skin dents and deep punctures). In addition, an electric clamping device can be installed on the processing table 2 to clamp and fix the root vegetables to improve the effect of subsequent processing.

[0036] Then, the electric push rod 4 is activated, which drives the top plate 6, which is fixedly connected to it, to move downwards a certain distance until the multiple cutters 12 are about to come into contact with the surface of the root vegetable.

[0037] If the visual camera 17 determines that the root vegetable has deep puncture wounds and superficial bruises, then multiple electric push rods 92 are controlled, with the movable end of each electric push rod 92 extending a certain distance. This, in turn, drives the movable frame 10, which is fixedly connected to it, to slide a certain distance away from the convex block 5 via the push plate 93. The movable frame 10 will then drive the gear 79 to rotate via the rack 101. The gear 79, in turn, drives the outer frame 74 to rotate around the pivot 73 by a certain angle via the rack 72 and the sliding block 71. The outer frame 74 will then drive the corresponding connecting plate 11 to rotate by a certain angle. The angle of inclination of the connecting plate 11 is increased so that the slider 76 drives the cutter 12 to rotate at a certain angle. At this time, the multiple cutters 12 move away from each other and the tilt angle increases. Then the electromagnetic push rod 75 is activated. The movable end of the electromagnetic push rod 75 drives the connecting plate 11, which is fixedly connected to it, to move a certain distance. This causes the connecting plate 11 to drive the cutter 12 to cut into the surface of the root vegetables through the slider 76. Since the tilt angle of the cutter 12 is large at this time (such as 45-60°), the cutter 12 cuts into the flesh of the root vegetables to a greater depth, which can remove the surface flesh and the deep flesh of the root vegetables.

[0038] During the movement of the cutter 12 driven by the slider 76 via the connecting plate 11, the connecting plate 11 will also drive the connecting rod 743 fixedly connected to it to move. Since the solenoid valve 1 inside the connecting pipe 747 is closed at this time, the connecting rod 743 will slide a distance in a sealed manner with the piston ring 742 and compress the return spring 744 until the cutter 12 completes the cutting operation. Then, the solenoid valve 1 inside the connecting pipe 747 will be opened. Under the action of the return spring 744, the piston ring 742 will slide a distance in a sealed manner, and then the mineral oil inside the connecting groove 746 will be drawn into the cylinder 741 through the connecting pipe 747, so that the connecting groove 746 and the slider 76 move a distance closer to the connecting pipe 747. Then the slider 76 will drive the cutter 12 fixedly connected to it to move a distance in sync, so that the cutter 12 will squeeze the cut root vegetable pulp to increase the squeezing force between the root vegetable pulp, which will facilitate the subsequent removal of the root vegetable pulp.

[0039] Then, the motor 18 is started. The output end of the motor 18 drives the crankshaft 88, which is fixedly connected to it, to rotate. The crankshaft 88 then drives the convex block 5 to rotate through the separation box 85 and multiple columns 81. The convex block 5 will then drive multiple moving frames 10 to rotate synchronously. Each moving frame 10 drives the corresponding cutter 12 to rotate, thereby performing a rotary cut on the flesh of the root vegetable, making it easier to remove the cut flesh later.

[0040] During the initial stage, as the movable frame 10 slides to adjust the cutting angle of the cutter 12, the rack 72 will also drive the sampling tube 14, which is rotatably connected to it, to move a certain distance. The sampling tube 14 and the movable frame 10 move in opposite directions, moving towards the deep puncture site of the root vegetables, so that the sampling area of ​​the sampling tube 14 is close to the puncture site of the root vegetables, and sampling and testing are performed on this more severely affected area. After the motor 18 starts, it will also drive the sampling tube 14 to rotate synchronously through the convex block 5 and the movable frame 10. An L-shaped guide rod 82 is fixedly connected to the side wall of the sampling tube 14. The L-shaped guide rod 82 and the bottom wall of the circular protrusion 83 always slide against each other. During each rotation of the sampling tube 14, the sampling tube 14 will reciprocate in the vertical direction. As a result, the sampling tube 14 will repeatedly insert itself into the area near the deep wound of the root vegetable in the vertical direction during the circumferential rotation. The pulp in this area will enter the sampling tube 14 for sampling. Since this pulp is close to the wound, the sampling is more representative.

[0041] Simultaneously, as the sampling tube 14 rotates around the motor 18, the crankshaft 88 will also drive the push rod 813 connected to its side wall to rotate, causing the corresponding piston plate 812 to slide back and forth sealed inside the corresponding separation box 810. The piston plate 812 draws gas from the annular block 87 and the separation box 85 through the one-way tube 815. After the gas pressure inside the separation box 85 decreases, gas is drawn from the multiple tubes 84. Under the action of pressure, the pulp that has entered the sampling tube 14 will enter the separation box 85 and then fall into the separation box 85 under the action of gravity. At the bottom of the chamber, the second solenoid valve in the discharge pipe 89 is opened to allow the sampled pulp to fall onto the sampling tray 816. This tray is used to send the sample directly to an online microbial detector or PCR instrument for testing to determine whether there is an infection in the punctured area of ​​the root vegetable. It should be noted that the root vegetable should not be placed on the conveyor roller 1 immediately. Instead, it should be transferred to a waiting area set up outside by the automatic pick-up device 16. The next step of processing will be carried out after the online detection results of the online microbial detector or PCR instrument are obtained.

[0042] If the visual camera 17 determines that the root vegetable only has epidermal damage, the operation method is the same as above. However, at this time, the movable end of the electric push rod 92 needs to be retracted a certain distance. Each moving frame 10 will move a certain distance towards the convex block 5, so that the outer frame 74 drives the corresponding cutter 12 to rotate a certain angle through the connecting plate 11 and the slider 76, reducing the tilt angle of the cutter 12 (e.g., reducing it to 30°). During this process, the sampling tube 14 will move a certain distance away from the convex block 5, so that the sampling tube 14 can sample and test the outer ring of the epidermal damage of the root vegetable. This area is located in the transition zone of the damage edge and is more representative (the cells here have just been subjected to mechanical stress and are in the critical stages of reactive oxygen species burst, enzyme activity change, and defense activation, which can truly reflect the early damage response). If the epidermal damage area of ​​the root vegetable is large, the purpose of cutting and sampling can be achieved by moving the placement position of the root vegetable.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
