Description

Technical Field

[0001] The present invention relates to the technical field of vacuum packaging technology for packaging containers and vacuum packaging tools, in particular to a vacuum packaging capping technology and capping tool for bottle caps of instant bird's nests, and particularly to a process flow and a mechanical connection structure of the capping tool. Background Art

[0002] Traditional instant bird's nests use a screw-mouth bottle cap structure, which makes it difficult to open and even more difficult to open in a low-temperature ring. The product packaging process is also relatively complicated. Summary of the Invention

[0003] The present invention aims to provide a vacuum capping tool that utilizes a snap-on compression mechanism, employing a resiliently repositionable compression component to compress the bottle cap. The tool utilizes temperature differences during processing to create a negative pressure within the bottle, resulting in a natural vacuum seal. The cap in this application is a screw-less, snap-on design consisting of a thin sheet of material that must exhibit a certain degree of elasticity and flexibility. This tool is intended to overcome the shortcomings and deficiencies of the prior art.

[0004] In order to achieve the above object, the technical solution of the present invention is: the production process comprises the following steps

[0005] S1. Place the product canned container 9 on the circular positioning part of the vacuum capping tool. The circular positioning part is provided with a cross-shaped drainage hole 2. The drainage hole 2 ensures that the liquid flowing out during sterilization can be discharged through the drainage hole 2. Place a non-gripping and non-threaded sealing cap 10 on the upper opening of the product canned container;

[0006] S2. Press the suspended end of the pressing component 3 of the vacuum pressing tool downward to fasten the sealing cover 10, and the roller 6 of the pressing component 3 presses the sealing cover 10 downward;

[0007] S3. Place the product canned container with the sealing cap 10 fastened thereon into a high-temperature and high-pressure autoclave for sterilization. Due to the elasticity and flexibility of the pressing component 3 of the vacuum capping tool, when the contents of the product canned container are heated to 70-80 degrees Celsius in the autoclave, they are maintained there for 8-15 minutes to allow the temperature of the contents to be balanced. During this heat-maintaining stage, most of the gas in the canned container is discharged from the container due to thermal expansion and contraction. Furthermore, due to the elasticity and flexibility of the pressing component 3, solid matter in the canned container is not discharged from the container, and a certain equilibrium state is maintained.

[0008] S4, then enters the high temperature sterilization stage above 100 degrees, and maintains the high temperature between 110 degrees and 130 degrees for 15-25 minutes. After the product sterilization is completed, the vacuum sealing and sterilization process of the canned container is completed, which can ensure the vacuum preservation of the food within the shelf life.

[0009] The vacuum capping tool includes a base plate with a drainage hole formed on the base plate. At least one clamping component is provided on the base plate. The clamping component is composed of two symmetrically distributed swing arms and a transverse pressure rod located between the upper ends of the swing arms. A roller is sleeved on the transverse pressure rod, and the swing arm has an elastic deformation structure or an elastic stretching reset structure.

[0010] The invention discloses a vacuum capping tool, which has the following technical effects: it can effectively press and fix bottle caps in the vacuum packaging process of non-threaded and non-gripping bottle caps; the tool has a simple structure, strong practicality, low manufacturing cost, easy daily maintenance, good working stability, and is easy to promote and apply.
