[0002] After tea is weighed and packaged into an inner packaging bag, it usually needs to be put into an outer packaging bag, and goes through multiple steps such as vacuum pumping, flattening the excess space of the outer packaging bag, and sealing. Currently, most tea packaging is done manually, which is time-consuming and laborious. Therefore, a vacuum packaging chamber is needed to solve this problem. Summary of the Invention

[0003] Other features and advantages of the present invention will be described in the following specification, and will become partially obvious from the specification, or can be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the specification and other accompanying drawings of the specification.

[0004] The objective of the present invention is to overcome the above deficiencies and provide a vacuum packaging chamber.

[0005] To achieve the above objective, the technical solution of the present invention is: a vacuum packaging chamber, including a vacuum chamber, the vacuum chamber includes a fixed body and a movable body, the movable body is slidably connected to the fixed body, the movable body is separated and combined with the fixed body through a driving mechanism, a heat sealing mechanism for pressing and sealing is arranged inside the vacuum chamber, a flattening mechanism for flattening the packaging is arranged inside the vacuum chamber, a lifting mechanism for lifting the packaging bag is arranged inside the vacuum chamber, and a blanking mechanism for pushing out the packaging bag is arranged on one side of the lifting mechanism.

[0006] By adopting the above technical solution, after the tea is packaged into the inner packaging bag, it enters the vacuum chamber from above the vacuum chamber and falls on the lifting mechanism. At this time, the driving mechanism drives the movable body to press on the fixed body to form a sealed space, and then the vacuum chamber is evacuated to form a vacuum environment, so that a vacuum is formed inside the outer packaging bag. Then, the heat sealing mechanism heat-presses and seals the entrance of the outer packaging bag, and at the same time, the pressing mechanism flattens the excess space on the outer packaging bag. After the operation is completed, the lifting mechanism moves the packaged tea bag to the blanking mechanism, and then the blanking mechanism pushes the tea bag out of the vacuum chamber. After the tea bag is pushed out, the lifting mechanism moves upward to reset, completing a packaging cycle. Through this method, automated packaging is achieved, saving manpower.
