DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, in this implementation: An automatic food packaging integrity detection device includes a detection table 1, which can convey the food to be detected onto the detection table 1. A support table 12 is fixedly installed in the middle of the back of the detection table 1. A cavity is formed inside the support table 12, and a plurality of hydraulic rods 14 are fixedly installed on the bottom inner wall of the cavity. A support plate 11 that penetrates and extends to the upper part of the support table 12 is arranged in the cavity formed inside the support table 12. A low-speed motor 15 is arranged on one side of the back of the support plate 11. A groove is formed on one side of the front of the support plate 11, and a rotating disk 2 is rotatably connected to the lower part of the groove formed on the front of the support plate 11. Starting the low-speed motor 15 can drive the rotating disk 2 to rotate. A sliding plate 13 is arranged in the upper part of the groove formed on the support plate 11. One side of the sliding plate 13 is hinged with a hinge rod 10, and the other end of the hinge rod 10 is hinged to one side of the rotating disk 2 and near the edge. When the hinge rod 10 moves, it can drive the sliding plate 13 to move. A moving plate 8 extending outside the support plate 11 is welded to the side of the sliding plate 13 away from the hinge rod 10. When the sliding plate 13 moves, it can drive the moving plate 8 to move, and an extrusion plate 9 is arranged below the moving plate 8. When the moving plate 8 moves, it can make the extrusion plate 9 move and can perform extrusion detection on the food packaging on the detection table 1.

[0021] In this embodiment, a mounting base is welded to the lower part of one side of the back surface of the support plate 11, which penetrates and extends into the cavity formed in the support table 12, facilitating the installation of the low-speed motor 15. The low-speed motor 15 is fixedly installed on the top surface of the mounting base by bolts. The output ends of multiple hydraulic rods 14 installed on the bottom inner wall of the cavity formed in the support table 12 are fixedly connected to the bottom surface of the support plate 11 and the bottom surface of the mounting base respectively. Starting the hydraulic rods 14 can move the support plate 11 and the mounting base. The output end of the low-speed motor 15 is connected to the center of the side of the rotating disk 2 away from the hinge rod 10. Starting the low-speed motor 15 can rotate the rotating disk 2. Chutes are formed on both sides of one side of the support plate 11 where the moving plate 8 is located, and sliders are placed in the chutes. The outer walls of the sliders are fixedly connected to both sides of the moving plate 8. The vertical cross-section of the chutes is T-shaped, enabling the moving plate 8 to slide up and down on the support plate 11. Positioning rods 6 are fixedly installed at the four corners of the top surface of the pressing plate 9, penetrating through the moving plate 8 and extending to the upper part of the moving plate 8. The top ends of the positioning rods 6 are welded with limiting plates 7. A spring 5 surrounding the outer circle of the positioning rods 6 is fixedly installed on the top surface of the pressing plate 9, and the other end of the spring 5 is fixedly connected to the bottom surface of the moving plate 8, which can play a buffering role when the pressing plate 9 presses the food packaging bag, preventing the pressing plate 9 from breaking the food packaging bag. Alarm lights 3 are installed on both sides of the top surface of the detection table 1 and below the pressing plate 9. An installation cavity is formed at the position between the two alarm lights 3 on the detection table 1. An electric push rod is fixedly installed on the bottom inner wall of the installation cavity, and the output end of the electric push rod is fixedly installed with a touch switch 4 that penetrates through and extends to the upper part of the detection table 1. The height of the touch switch 4 can be adjusted by the electric push rod. When the pressing plate 9 presses the food packaging bag on the detection table 1, if there is air leakage, at this time the pressing plate 9 can touch the touch switch 4, and at this time the alarm lights 3 start to light up, so that it can be known that the food packaging bag has air leakage.

[0022] Working principle and usage process of the present utility model: For this automatic food packaging integrity detection device, during use, first, the food to be detected is conveyed to the detection table 1. After that, the low-speed motor 15 can be started, which can drive the rotating disk 2 to rotate, and then drive the sliding plate 13 to move downward through the hinge rod 10. Further, the moving plate 8 can be made to move downward. At this time, the food packaging bag on the detection table 1 can be squeezed by the pressing plate 9. If there is air leakage, at this time, the pressing plate 9 can touch the touch switch 4, and the alarm lamp 3 starts to light up, so that it can be known that there is air leakage in the food packaging bag. At this time, it can be removed, avoiding the situation where manual pressing of the food packaging bag may cause arm soreness. At the same time, the height of the touch switch 4 and the height of the pressing plate 9 can be adjusted according to the size of the food packaging bag. At this time, the electric push rod can be started, and its output end can drive the height of the touch switch 4 to be adjusted. Then, the hydraulic rod 14 can be started, which can drive the support plate 11 and the mounting seat to move, and then drive the height of the pressing plate 9 to be adjusted through the moving plate 8, the spring 5, the positioning rod 6 and the limiting plate 7, so as to achieve the purpose of detecting the integrity of food packaging bags of different sizes.
