Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging and sealing machines, in particular to a tea packaging and sealing machine with an air extraction structure. Background Art

[0002] As a popular beverage, the packaging process of tea is crucial to maintaining the freshness and quality of tea. As consumers' requirements for tea quality increase, tea packaging technology is also constantly improving. At present, most packaging technologies use vacuum packaging operations. When performing vacuum packaging operations, corresponding tea packaging and sealing machines are usually used. Most tea packaging and sealing machines are capable of extracting the air in the packaging bag and then performing heat sealing operations to achieve the effect of vacuum packaging.

[0003] The utility model patent with authorization announcement number CN220764830U discloses a foot-operated plastic sealing machine with a vacuum structure, including a base, a plurality of supporting columns fixedly arranged on the lower surface of the base, a placement plate fixedly connected in the middle of the plurality of supporting columns, a sealing device including a lower heat sealing head, an upper heat sealing head arranged on the upper surface of the lower heat sealing head, a plurality of springs installed between the upper heat sealing head and the lower heat sealing head, a connecting rod fixedly installed at the center of the lower surface of the upper heat sealing head, a pedal fixedly arranged at one end of the connecting rod, and the sealing device also including a power supply. The operation is simple during use. The foot-operated plastic sealing machine with a vacuum structure can more effectively extract the air in the packaging bag when in use, and avoid the residual gas in the packaging bag causing the tea to become moldy and damaged. At the same time, the foot-operated sealing machine can better seal the packaging bag, and it is also more convenient for the operator to take and check after sealing, thereby improving the sealing efficiency of the packaging bag and making the packaging bag more beautiful.

[0004] Although this technical solution has the advantages of better sealing of packaging bags, making it easier for operators to pick up and inspect after sealing, improving the sealing efficiency of packaging bags, and making packaging bags more aesthetically pleasing, this technical solution, when used in practice, completes the heat sealing operation by pressing down the pedal to drive the upper heat sealing head against the lower heat sealing head. During this process, since heat sealing requires a certain amount of time, the user needs to step on the pedal for a certain period of time. Repeated long-term stepping operations can easily cause soreness and swelling in the feet. In addition, during the process of stepping on the pedal, it is easy for the upper heat sealing head to not be able to properly press against the lower heat sealing head due to the upward movement of the foot, affecting the heat sealing effect and causing inconvenience to the user. In view of this, we proposed a tea packaging and sealing machine with an exhaust structure. Utility Model Content
