8. A continuous food vacuum packaging device as claimed in claim 7, characterized in that: The telescopic assembly (5) comprises a hydraulic cylinder (501) arranged on the upper surface of the steering plate (403); the upper surface of the steering plate (403) is bolted to a fixing frame (502); the hydraulic cylinder (501) is located in a groove of the fixing frame (502); and the hydraulic cylinder (501) is fixedly connected to the support plate (601).

9. A continuous food vacuum packaging device as claimed in claim 8, characterized in that: A support frame (8) is fixedly connected to the peripheral side of the packaging machine (1), the support frame (8) is fixedly connected to the mounting plate (2), and a support plate (9) is fixedly mounted on the upper surface of the packaging machine (1).

10. A packaging method for food continuous vacuum packaging equipment according to any one of claims 1 to 9, characterized in that: include, S1: A first conveyor belt arranged in a vertical direction transports the packaging bag to a packaging machine (1); S2: The lifting motor (302) drives the driving wheel (303) to reverse, and the driving wheel (303) drives the belt (304) to move, so that the lifting plate (305), the synchronous plate (306), the sliding plate (307) and the supporting plate (601) move downward along the guide plate (309), thereby driving the steering assembly (4), the telescopic assembly (5), the clamping assembly (6) and the synchronous assembly (7) to move downward until the height of the first lifting plate (604) and the second lifting plate (704) is lower than the packaging bag; S3: The electric push rod (602) drives the first movable plate (603) to move along the guide rod (702). Since the gear (707) is respectively engaged with the first tooth plate (705) and the second tooth plate (706), the electric push rod (602) also drives the second movable plate (703) to move. At this time, the first movable plate (603) and the second movable plate (703) are close to each other, so that the first lifting plate (604) and the second lifting plate (704) are moved to the bottom of the packaging bag; S4: the lifting motor (302) reverses, the lifting component (3) moves the packaging bag upward, and then the steering motor (402) drives the steering plate (403) to rotate forward 45 degrees, rotating the packaging bag to the top of the packaging machine (1). Then the lifting motor (302) rotates forward, the lifting component (3) drives the packaging bag to move downward to the upper surface of the packaging machine (1), and makes the two ends of the packaging bag respectively located on the sealing strip and the drag plate of the packaging machine (1). Then the electric push rod (602) drives the first movable plate (603) and the second movable plate (703) to move away from each other, completing the placement of the packaging bag. The steering component (4) rotates forward 45 degrees again to remove the clamping component (6) from the packaging machine (1), and the hatch of the packaging machine (1) is closed to carry out the vacuuming and sealing process. 5S: The hatch of the packaging machine (1) is opened, the steering assembly (4) rotates 45° in the opposite direction and moves to the top of the packaging machine (1), and the sealed packaging bag is lifted by the cooperation of the lifting assembly (3), the clamping assembly (6) and the synchronization assembly (7). The steering assembly (4) rotates 45° in the forward direction and places the sealed packaging bag on a second conveyor belt arranged along the horizontal direction. The sealed packaging bag is sent away by the second conveyor belt, and the steering assembly (4) is reset to the starting position to prepare for processing the next packaging bag.
