[0037] When the utility model is working: the reduction motor 34 is started by the controller 21, and the reduction motor 34 drives the driving shaft 28 to rotate, and the active roller 29 on the driving shaft 28 rotates accordingly, and the driven roller 31 is driven to rotate through the conveyor belt 32, and the pickle package is placed on the conveyor belt 32 and transported forward under the action of the conveyor belt 32. At the same time, the limit strips 36 on both sides limit the position of the pickle package during the transmission process to ensure that the pickle package is transmitted at the appropriate position. When the pickle package runs to the bottom of the detection cover 16 with the conveyor belt 32, the position sensor 20 detects the position information of the pickle package and transmits it to the controller 21. The controller 21 controls the detection electric cylinder 15 to start, and the detection electric cylinder 15 pushes the detection cover 16 to move downward, so that the silicone sealing ring 33 at the bottom of the detection cover 16 is tightly fitted with the upper surface of the conveyor belt 32, covering the pickle package to form a sealed space. The vacuum generator 18 is started under the control of the controller 21 to vacuum the space inside the detection cover 16 to form a vacuum environment inside. During this process, the pressure sensor 19 monitors the pressure inside the detection cover 16 in real time The controller 21 detects the pressure change and transmits the pressure data to the controller 21. The controller 21 judges the tightness of the pickle package based on the pressure data transmitted by the pressure sensor 19. If the pressure change is within the normal range, it indicates that the package is well sealed. If the pressure change exceeds the preset threshold, it is determined that there is a leakage problem in the package. If the pickle package is unsealed, after the detection cover 16 is raised, the controller 21 starts the reduction motor 34 to transport the pickle package to the bottom of the electric nozzle 27. The controller 21 controls the coding electric cylinder 24 to start, and the coding electric cylinder 24 pushes the liquid storage tank 25 downward. At the same time, the distance sensor 37 monitors the distance between the electric nozzle 27 and the pickle package in real time. When the electric nozzle 27 moves to the preset distance from the pickle package, the position information is fed back to the controller 21. The controller 21 controls the electric nozzle 27 to code the unqualified pickle package based on this information for subsequent sorting and processing. After completing one detection and coding operation, the device continues to detect subsequent pickle packages and repeats the above steps to achieve online continuous detection of the tightness of pickles.
