The movable sealing plate 4-4 and the fixed sealing plate 4-5 prevent the granular dust from overflowing. At the same time, the raised granular dust is extracted through two exhaust pipes (which can be connected to a vacuum pump), which can effectively reduce the dust floating in the packaging bag. After the packaging bag is loaded, repeat step one and remove the packaging bag.

4. A multifunctional bagging and air extraction tooling according to claim 1, characterized in that: The top surface of the movable sealing plate presses against the bottom surface of the bottom cover.

5. A loading method of a multifunctional bagging and air extraction tooling according to any one of claims 1 to 4, characterized in that: Specifically as follows: Step 1: Manually pull the drawstring. The drawstring bypasses the fixed pulley and drives the synchronous frame to move upward along the feed pipe and the two extraction pipes through the connecting plate. All four driving springs are compressed. The synchronous frame drives the first link of the two clamping mechanisms to move upward along the corresponding vertical chutes on the fixed frame respectively. The clamping plates of the two clamping mechanisms are driven to open outward through the corresponding second links and third links respectively. At the same time, the inner support side frames of the two inner support mechanisms move inward along the corresponding planar cam grooves and inner support side frame chutes on the synchronous frame through the inner support side frame pulleys respectively. The movable sealing plates of the two inner support mechanisms remain stationary relative to the bottom cover, and the sealing plate chutes of the inner support mechanisms move inward relative to the movable sealing plates. Step 2: Put the packaging bag outside the fixed frame and the two inner support mechanisms and inside the clamping plates of the two clamping mechanisms. Loosen the drawstring. The synchronous frame and the connecting plate move downward along the feed pipe and the two extraction pipes due to their respective weights and the restoring force of the driving springs. At the same time, the first link of the two clamping mechanisms on the synchronous frame moves downward along the corresponding vertical chutes on the fixed frame respectively. The clamping plates of the two clamping mechanisms are driven to move inward by the corresponding second links, third links and the restoring force of the corresponding torsion springs. The lower ends of the clamping plates of the two clamping mechanisms clamp the bag mouth outside the fixed frame. At the same time, the inner support side frames of the two inner support mechanisms move outward along the corresponding planar cam grooves and inner support side frame chutes on the synchronous frame through the inner support side frame pulleys respectively. The movable sealing plates of the two inner support mechanisms remain stationary relative to the bottom cover, and the fixed sealing plates and the sealing plate chutes of the inner support mechanisms move outward relative to the movable sealing plates, and the fixed sealing plates always fit with the movable sealing plates. At this time, the U-shaped plates of the two adaptive adjustment mechanisms are both pressed to move inward, and drive the U-shaped plate positioning blocks and the guiding supports to move inward along the corresponding guiding grooves. Under the combined action of the two inner support mechanisms and the two adaptive adjustment mechanisms, the inside of the packaging bag is tightened. Then, granular materials are loaded into the packaging bag through the feed pipe. During the feeding process, the seal prevents particulate dust from entering the adaptive adjustment mechanism, and the movable sealing plate and the fixed sealing plate prevent the particulate dust from spilling out. At the same time, the raised particulate dust is extracted through the two extraction pipes. After the packaging bag is filled, repeat Step 1 to remove the packaging bag.
