The utility model relates to the technical field of thermos
bottle processing, and discloses a sealing performance detection structure for thermos
bottle liner production, which comprises a bottom plate, two vertical plates are fixedly mounted on two sides of the upper surface of the bottom plate, feeding holes are formed in the surfaces of the vertical plates on the two sides, an
inductor is mounted in the middle of the upper surface of the bottom plate, and the upper surface of the bottom plate is connected with the
inductor. The sealing performance detection structure comprises a bottom plate, four vertical rods are fixedly installed on the upper surface of the bottom plate, the four vertical rods are arranged on the upper surface of the bottom plate in a
rectangular array mode, four springs are fixedly installed on the upper surface of the bottom plate, and the four spring sleeves are arranged on the outer surfaces of the vertical rods in a sleeving mode. The sleeve ring at the bottom of the pressing plate is sleeved on the
bottle opening of the thermos bottle liner, the sealing ring is arranged in the sleeve ring, so that air leakage can be prevented when the inside of the thermos bottle liner is detected, and the air outlet hole in the sleeve ring can enable air to be conveyed into the bottle liner, so that the detection effect of the sealing performance of the thermos bottle liner is more accurate.
