Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tea production, and in particular relates to a sealing detection device for bagged tea. Background Art
[0002] As a leading health product, tea should ensure that its quality is not affected or is reduced to the maximum extent within a certain period of time, effectively extend the shelf life of tea, and allow consumers to buy tea products with intact color, fragrance, taste and shape. Tea storage is a process to ensure that tea maintains its original quality on the basis of basic packaging. Tea has strong moisture and odor absorption, and it is easy to absorb moisture and odor in the air. If the storage method is slightly improper, it will lose its flavor in a short period of time, and the more precious tea leaves are fermented, the more difficult it is to preserve. Therefore, mastering the storage method of tea to ensure the quality of tea is essential in life, so when producing tea, it is necessary to test the sealing performance of bagged tea.
[0003] After my search, the prior art discloses a packaging bag sealing detection device (application number 201921319224.3), including a sealing cylinder, and a scale mark indicating the volume of the internal solution medium is provided on the side wall of the sealing cylinder; a sealing cover is provided above the sealing cylinder, and a raised ring portion extending downward is provided on the sealing cover, and the raised ring portion is located in the sealing cylinder and forms a sealing fit with the sealing cylinder through a first sealing ring, and the sealing cover is provided with an air joint connected to the concave cavity, and the air joint is connected to the air suction port of an external vacuum pump through an air pipe, and an air circuit ball valve is connected in series on the air pipe.
[0004] The packaging bag sealing detection device disclosed in the above-cited document is a device that randomly samples packaged products and puts them into water. It then creates a pressure difference inside and outside the packaging bag by vacuuming the bag and observes whether bubbles emerge. However, it does not prevent the packaged products from floating up during the detection. It uses heavy objects to press the products into the water. This method is not only cumbersome, but the contact part between the packaging bag and the heavy object may block the leak, resulting in certain detection errors.
[0005] In view of this, the present utility model is proposed. Utility Model Content
[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:
