[0030] Working principle: The extension end of the adjusting cylinder 7 is fixedly connected to the side of the inner partition plate 8, so that the inner partition plate 8 and the fixed side plate 6 are arranged parallel to each other. The side of the inner partition plate 8 has a through side groove 9, which provides a specific channel for the transmission of plastic parts. The top opening end of the collecting tank 5 is located near the bottom end of the guide tube 4, which is used to collect plastic parts that do not meet the specifications. The output end of the side cylinder 16 extends horizontally and is fixedly connected to the side of the movable inner block 17, which is used to adjust the horizontal position of the movable inner block 17. A push cylinder 10 is fixedly connected to one side of a fixed side plate 6. The output end of the push cylinder 10 extends horizontally and is fixedly connected to the side of the push plate 11. The push plate 11 is engaged with the side of the fixed side plate 6, which is used to push plastic parts that do not meet the specifications. The transmission motor 19 is started, which drives the transmission roller 21 to rotate, thereby starting the transmission belt 3 to run. Based on the width of the plastic part, the adjusting cylinder 7 is activated, pushing the inner partition plate 8 to a specified width spacing, allowing the plastic part to move horizontally along the position between the fixed side plate 6 and the inner partition plate 8 under the transmission of the conveyor belt 3. When the plastic part moves to the appropriate position, the side cylinder 16 is activated, adjusting the movable inner block 17 to move to a specified point on the bottom surface of the movable base plate 15, so that the inflation head 18 is aligned with the top opening end of the plastic part. Then, the telescopic upright 12 and the top cylinder 14 begin to telescopically move, driving the movable inner block 17 downward to press down at the top opening end position of the plastic part, and the inflation head 18 is inserted into the inner side of the opening of the plastic part. At the same time, the sealing rubber plate structure on the bottom surface of the movable inner block 17 is tightly fitted with the opening of the plastic part to ensure good sealing. Air is inflated into the plastic part through the external air pump structure connected to the inflation head 18, and the main pressure gauge 24 detects the air pressure changes inside the plastic part in real time. If the plastic parts have good air tightness, the air pressure will remain within a certain range; if the air tightness does not meet the specifications, the air pressure will change abnormally. After the inspection is completed, for plastic parts that meet the specifications, the conveyor belt 3 continues to transport them to the next process; for plastic parts that do not meet the specifications, the push cylinder 10 is activated, and the push plate 11 pushes the plastic parts that do not meet the specifications through the through side groove 9 on the side of the partition inner plate 8 to the other side of the partition inner plate 8. Then the plastic parts slide down through the guide tube 4 into the collection tank 5 for separate collection and processing.
