Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2017/219176
Kind Code:
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.
