At this time, the clamping mechanism 5 jaw 512 is opened, and is moved forward to the rear side of the material packaging under the driving of the air cylinder 508. At this time, the jaw 512 clamps the material bag opening under the driving of the jaw opening and closing air cylinder 513. At this time, if the packaging is a "two-sided" type of packaging, the first shaping press plate 603 and the second shaping press plate 604 move towards each other under the driving of the opening and closing motor 632 to clamp and shape the material into a two-sided shape. At this time, the lower bearing mechanism 4 rotates 90 degrees to the left or right to rotate the shaping mechanism 6 directly below the stoma vacuum mechanism 10. At this time, the stoma vacuum mechanism 10 moves downward to complete vacuumizing and pre-sealing the material packaging.

At this time, the receiving mechanism 7 rotates to the position of the secondary vacuum shaping mechanism 3 with the rotation of the lower bearing mechanism 4. At this time, the guide rod of the turning air cylinder 707 retracts to place the material packaging on the conveyor belt 312. Then the material packaging is sent below the upper cover 300, and the upper cover 300 moves downward under the driving of the lifting air cylinder 302 until it completely adheres to the conveyor belt. At this time, the press plate 305 moves downward under the driving of the press plate air cylinder 306 until the material packaging is pressed flat to a "two-sided" state. At this time, the secondary vacuum shaping mechanism 3 performs secondary vacuumizing and sealing on the upper cover 300. Then the conveyor belt 312 moves to the left to the next station,

[0196] If the package is "six face" type, the side mold is installed into the side mold installation mechanism 616 according to the different packaging by artificial, when the material package is put into the first shaping press plate 603 and the second shaping press plate 604 and the side mold, the first shaping press plate 603 and the second shaping press plate 604 move towards each other, while the two side mold installation mechanisms 616 move towards each other under the drive of the second cylinder 623, so that the material package bag forms a cube with edges, at this time, the lower bearing mechanism 4 rotates 90 degrees to the left or right to rotate the shaping mechanism 6 directly below the stoma vacuum mechanism 10, at this time, the stoma vacuum mechanism 10 moves down to complete vacuumizing and sealing of the material package. At this time, the clamping mechanism 5 opens the clamping jaw 512 and moves backward under the drive of the cylinder 508, at this time, the stoma vacuum mechanism 10 clamps the material package and moves upward to pull out the material package from the shaping mechanism 6 (at this time, the front and rear press plates of the shaping mechanism 6 and the two side mold installation mechanisms 616 are opened at the same time), at this time, the lower bearing mechanism 4 rotates 90 degrees to the right or left, rotates the receiving mechanism 7 to the position below the stoma vacuum mechanism 10, and the stoma vacuum mechanism 10 puts the package on the receiving tray 709 (the initial state of the receiving tray 709: the guide rod of the turnover cylinder 707 extends to rotate the receiving tray 709 upward, when the material package is put into the receiving tray 709, the positioning cylinders 708 on both sides extend to fix the package in the middle of the receiving tray), at this time, the receiving mechanism 7 is rotated to the position of the secondary vacuum shaping mechanism 3 with the rotation of the lower bearing mechanism 4, at this time, the guide rod of the turnover cylinder 707 retracts to place the material package on the conveyor belt 312 (when the six face vacuum is performed, the upper cover 300 always remains in the upper position without action), and is conveyed to the next station through the conveyor belt 312.

[0197] The application also provides a working method of a two-surface and six-surface integrated vacuum packaging machine according to any one of the above embodiments:
