s6, cotton is loaded again, S2-S5 is repeated for a plurality of times until the last time of loaded cotton is compressed, and the sealing plate (6) is positioned at the opening end of the shaping box (2) and does not move downwards any more; in the process, when cotton is gradually compressed, the volume in the knitting bag (5) gradually reaches the upper limit, and the elastic belt (52) is limited by the telescopic end of the air suction cylinder (44) to further tighten, so that elastic potential energy is formed;
s7, forming a rebound space, retracting a middle expansion joint of the multi-stage servo electric cylinder (41), extending a tail expansion joint, and keeping the retraction amount and retraction speed of the middle expansion joint consistent with the extension amount and extension speed of the tail expansion joint; in the step, the interval between the pushing plate (42) and the sealing plate (6) is gradually increased, when the interval distance between the pushing plate and the sealing plate reaches the set distance, a rebound space is formed, and the multi-stage servo electric cylinder (41) is stopped;
s8, releasing and sealing, retracting the telescopic end of the release cylinder (53), releasing the constraint of the elastic belt (52), driving the wrapping edge (51) to overturn when the elastic belt (52) rebounds, and covering the edge of the upper side surface of the sealing plate (6) after the wrapping edge (51) is overturned, so that the wrapping edge (51) and the magic tape (7) on the sealing plate (6) are mutually adhered to form a package;
s9, removing adsorption and resetting, stopping the suction of the suction cylinder (44), removing the adsorption to the sealing plate (6), resetting each expansion joint of the pressing mechanism (4), and stopping the vacuum machine (22);
s10, lifting and transferring, starting an air compressor (34), inflating the air bag (31), gradually pushing the lifting plate (33) upwards when the air bag (31) is inflated, lifting the package on the lifting plate (33) to the box opening of the shaping box (2), and transferring the package.
2.

3. The packaging and sealing method of a logistics packaging apparatus based on vacuum compression and automatic sealing according to claim 1, characterized in that: the shaping box (2) is a rectangular hollow box body with an opening at the upper end, and vacuum meshes (21) are respectively arranged at each side of the lower end of the rectangular hollow box body and are communicated with the vacuum machine (22).
4. The packaging and sealing method of a logistics packaging apparatus based on vacuum compression and automatic sealing according to claim 1, characterized in that: the inflation jacking mechanism (3) comprises an air pipe (32) communicated with the bottom of the air bag (31) and a jacking plate (33) covered at the upper end of the air bag (31), and the other end of the air pipe (32) is connected with an air compressor (34); a three-way electromagnetic valve (35) is arranged on the air pipe (32).
5. The packaging and sealing method of a logistics packaging apparatus based on vacuum compression and automatic sealing according to claim 1, characterized in that: the pressing mechanism (4) comprises a pressing plate (42) connected with the multistage servo electric cylinder (41), the fixed end of the multistage servo electric cylinder (41) is fixed on the frame (43), and the supporting legs of the frame (43) are fixed on the base plate of the base (1).
6. The method for packaging and sealing a logistics packaging apparatus based on vacuum compression and automatic sealing according to claim 5, wherein: an air suction cylinder (44) is arranged in a cavity of a tail expansion joint of the multistage servo electric cylinder (41), and when an air suction expansion end of the air suction cylinder (44) stretches out of the tail expansion joint or stretches into the tail expansion joint.
7. The packaging and sealing method of a logistics packaging apparatus based on vacuum compression and automatic sealing according to claim 1, characterized in that: the side edge of the wrapping edge (51) is provided with an elastic belt (52), the elastic belt (52) is hooked with the telescopic end of a release cylinder (53), and the release cylinder (53) is connected with the shaping box (2).
