vacuum packaging machine

Abstract

The invention discloses a vacuum packaging machine. The vacuum packaging machine is characterized by comprising a workbench which is fixedly arranged, a turnplate is rotatably arranged on the workbench, multiple vacuum chamber units are uniformly distributed on the outer circumference of the turnplate and correspond to a bag feeding workstation, a closing workstation, a vacuumizing workstation, a thermal sealing workstation, a cooling workstation, an exhausting workstation and an uncovering workstation of the workbench respectively, a bag feeding mechanism is arranged on the bag feeding workstation, each vacuum chamber unit comprises a vacuum chamber with an upturning cover door, a thermal sealing component and a bag clamping component, each thermal sealing component and the corresponding bag clamping component are arranged in the corresponding vacuum chamber, opening and closing of the cover doors are driven by an uncovering cylinder, each thermal sealing component is provided with a thermal sealing cylinder, an air distribution mechanism is arranged in the middle of the turnplate and comprises a rotating disc and an air distribution disc, the rotating disc rotates synchronously along with the turnplate, the air distribution disc is fixedly mounted on the workbench, and the rotating disc is provided with multiple vacuum chamber communicating holes which are communicated with the vacuum chambers, and multiple thermal sealing cylinder communicating holes which are communicated with air incoming holes of the thermal sealing cylinders. The vacuum packaging machine is used for vacuum packaging of packaging bags and is simple in structure, high in production efficiency and high in vacuum packaging quality.

Description

technical field [0001] The invention relates to a turntable vacuum packaging machine used for vacuum packaging of packaging bags. Background technique [0002] At present, a lot of food packaging has been vacuum-packed, and the shelf-life of vacuum-packed food can be greatly improved. Vacuum packaging is completed by vacuumizing the unsealed packaging bag in a vacuum chamber. Carry out vacuum packaging of food. The turntable vacuum packaging machine generally consists of a turntable and a plurality of vacuum chambers arranged around the turntable. When working, the index rotation of the turntable drives all the vacuum chambers to rotate synchronously. During the index rotation of the turntable, each vacuum chamber is completed separately. Actions such as bagging, closing, vacuuming, heat sealing, cooling, exhausting and opening. However, the structure of the rotary table vacuum packaging machine in the prior art is unreasonable and relatively complex, including the structu...
