The receiving bottom plate is convenient for lifting and adjusting by the lifting cylinder. The first opening is convenient for limiting the first push plate. The rotating round table is convenient for limiting its rotation by cooperating with the limiting round plate through the circular plate slot. The first servo motor drives the first gear to rotate. The first gear engages with the meshing teeth and then drives the rotating round table to rotate. The rotating round table is convenient for adjusting the angle of the freeze-dried fruit packaging bag, which is convenient for assisting multi-angle detection and can reduce the detection blind area.

When the freeze-dried fruit packaging bag has a hole, a large amount of air will leak out under the strong squeezing and will be discharged through the air vent. The pneumatic fluff is very light. By observing whether the pneumatic fluff swings, you can visually observe whether there is a gas leak. If the pneumatic fluff does not swing, it means that there is no problem with the sealing of the freeze-dried fruit packaging bag. Secondly, there may be a slight air leak in the sealing of the freeze-dried fruit packaging bag.

When the freeze-dried fruit packaging bag has a hole, a large amount of air will leak out under the strong squeezing and will be discharged through the air vent. The pneumatic fluff is made of very light material. By observing whether the pneumatic fluff swings, it can be intuitively observed whether there is a gas leak. If the pneumatic fluff does not swing, it means that there is no problem with the sealing of the freeze-dried fruit packaging bag, and there may be a slight air leak in the sealing of the freeze-dried fruit packaging bag.

10. The method for using the freeze-dried fruit packaging bag sealing detection device according to claim 1, characterized in that: The operation process steps are as follows: S1: The first cylinder (202) drives the first push plate (203) to maintain a fixed frequency to push the freeze-dried fruit packaging bag onto the receiving bottom plate (221), so as to facilitate sampling inspection of the sealing of the freeze-dried fruit packaging bag. The receiving bottom plate (221) is convenient for lifting and adjusting by the lifting cylinder (222). The first opening (204) is convenient for limiting the first push plate (203). The rotating circular table (226) is convenient for limiting its rotation by cooperating with the limiting circular plate (225) through the circular plate slot (223). The first servo motor (229) drives the first push plate (203) to rotate. The first gear (228) is driven to rotate, and the first gear (228) is engaged with the meshing teeth (227) to drive the rotating table (226) to rotate. The rotating table (226) is convenient for adjusting the angle of the freeze-dried fruit packaging bag, and is convenient for assisting in multi-angle detection, which can reduce the detection blind area. The freeze-dried fruit packaging bag with no problem in the random inspection will drive the second push plate (208) to extend and retract through the second cylinder (207), and push the freeze-dried fruit packaging bag to the freeze-dried fruit packaging bag conveyor (1) for further transportation. The freeze-dried fruit packaging bag with problem needs manual quality inspection and classification. S2: The second servo motor (306) drives the second gear (304) to rotate, and the second gear (304) drives the spur rack (303) to adjust the lifting and lowering, thereby facilitating the control of the lifting and lowering of the sealing cover (301). The sealing cover (301) is convenient for covering and sealing the freeze-dried fruit packaging bag. The fourth cylinder (385) is convenient for fixing the freeze-dried fruit packaging bag through the clamping plate (386). The freeze-dried fruit packaging bag is in an inflated state, and the freeze-dried fruit is a hard food. It is not easy to cause damage to the food when clamping. The anti-slip protrusion (387) can improve the stability of the clamping. The cylinder (382) drives the lifting slide (381) to move up and down inside the lifting slide (307), thereby lifting the frozen-dried fruit packaging bag held therein. The third gear (383) on the fourth cylinder (385) is conveniently rotated and adjusted via the rotating shaft (384), thereby facilitating multi-angle detection of the sealing performance of the frozen-dried fruit packaging bag. Through the meshing connection between the three third gears (383), the electric motor (388) drives one of the third gears (383) to rotate, thereby conveniently driving the frozen-dried fruit packaging bag to rotate in a circle, thereby facilitating the inspection of the sealing performance of different areas. S3: During the initial inspection, the air outlet (401) is open, and the fourth cylinder (385) drives the clamping plate (386) to squeeze the freeze-dried fruit packaging bag without damaging the freeze-dried fruit and the packaging bag. When there is a hole in the freeze-dried fruit packaging bag, a large amount of air will leak out under the strong squeezing and will be discharged through the air outlet (401). The pneumatic fluff (404) is made of very light material. Observing whether the pneumatic fluff (404) swings can visually observe whether there is gas leakage. If the pneumatic fluff (404) does not swing, it means that there is no problem with the sealing of the freeze-dried fruit packaging bag. The second problem is that there may be a slight air leak in the seal of the freeze-dried fruit packaging bag. It is necessary to use the fifth cylinder (406) to drive the sealing top plate (405) to slide on the inner wall of the limiting slide groove (402) to facilitate the sealing of the air outlet (401). The sealing cover (301) is connected to the sealing card groove (302), the air outlet (401) remains closed, and the inside of the sealing cover (301) remains sealed. The sealing detector (309) can further detect the fine sealing of the freeze-dried fruit packaging bag, and then complete the sampling test of the sealing of the freeze-dried fruit packaging bag, thereby improving the accuracy of the test.
