The sealing device includes a bag conveying mechanism, a sealing module, and a module conveying mechanism. The sealing module includes a base and an actuator, and a first sealing block and a second sealing block arranged on the base. The actuator is configured to open and close the clamping opening and includes a push rod and a horizontal actuation track. When the sealing module is moved along the conveying path of the module conveying mechanism, the horizontal guide post slides along the horizontal actuation track, and the horizontal actuation track drives the push rod via the horizontal guide post to move horizontally. Thus, the clamping opening is opened or closed.

A sealing device, comprising: a bag transmission mechanism (200), a sealing module (300), and a module transmission mechanism (100). The sealing module (300) comprises a base (310) and an execution mechanism (320), as well as a first sealing block (330) and a second sealing block (340) which are provided on the base. The execution mechanism (320) is used for opening and closing a clamping opening (331) and comprises a push rod (321) and a horizontal execution rail (325). When the sealing module (300) moves along a transmission path of the module transmission mechanism (100), a horizontal guide column (322) slides along the horizontal execution rail (325). The horizontal execution rail (325) drives the push rod (321) by means of the horizontal guide column (322) to horizontally move so as to open and close the clamping opening (331). The device only needs to evacuate a small amount of air in a bag. Moreover, a large number of positions for vacuum pumping and nitrogen filling are available. Multiple packaging bags are subject to vacuum pumping and nitrogen filling at the same time in a period, thereby greatly improving the production efficiency. The device has a simple structure and is convenient to use and low in maintenance costs, so that the device can be widely applied and promoted.
