After the vacuum reaches a certain vacuum degree, the heat sealing assembly heat-seals the packaging bag, and then the vacuum air pipe of the vacuum cavity passes through the exhaust groove, so that air enters the vacuum cavity and becomes a normal pressure state. Then, at the lower bag position, the movable cover of the vacuum cavity is opened, and the machine clamp assembly releases the clamping of the packaging bag, so that the packaging bag will fall into the vacuum cavity, and then the vacuum cavity reaches the upper bag position, and the above actions are repeated. During the above-mentioned action process, multiple vacuum chambers work synchronously, and multiple chambers are arranged side by side horizontally in each vacuum chamber, that is, each vacuum chamber can be loaded with multiple packaging bags at the same time, which improves efficiency and has a simple and compact structure. In addition, during the circular rotation of the vacuum chamber with the turntable, all vacuum chambers will maintain their own state unchanged, which facilitates operation.

The opening and closing of the movable cover 2 is driven by a cover cylinder. The cover cylinder is fixedly installed on the back of the vacuum chamber 1. A machine clamp assembly and a heat sealing assembly are provided in the vacuum chamber 1. The vacuum chamber 1 is fixedly connected to the flip shaft 5 and can be flipped and connected to the turntable through the flip shaft 5. Four vacuum chambers 1 are arranged along the circumference of the turntable. The turntable is composed of a left turntable 32 and a right turntable 31 respectively arranged on the left and right sides of the vacuum chamber 1. The left turntable 32 and the right turntable 31 are fixedly connected by a central shaft 9. The central shaft 9 is driven by a turntable motor 10 through a belt, and drives the turntable to rotate intermittently in a circle during operation. The sun gear 8 is set at the rotation center of the right turntable 31, and the sun gear 8 is fixedly connected to the frame 15. The shaft end of the flip shaft 5 is fixedly connected to the planetary gear 6. The planetary gear 6 is driven by the intermediate gear 7 to engage the sun gear 8, so that when the turntable rotates in a circular motion during operation, the vacuum chamber does not rotate in a circular motion; the outer side of the left turntable 32 is provided with an inner disk 14, a gas distribution disk 13 and an outer disk 12 that are sealed and fitted with each other. The inner disk 14 rotates in a circular motion synchronously with the turntable (the inner disk 14 and the central shaft 9 are connected by a sliding key), the gas distribution disk 13 and the outer disk 12 are fixedly installed relative to the frame 15, and a spring is provided to hold the inner disk 14 in place. 4 is pressed against the end surface of the gas distribution disk 13 so that the inner disk and the gas distribution disk are in close contact. The gas distribution disk 13 is provided with an exhaust groove 18 and an exhaust groove. The exhaust groove 18 is externally connected to the exhaust pipe 16, and the exhaust groove is externally connected to the exhaust pipe 17. The exhaust pipe 16 and the exhaust pipe 17 are fixedly installed on the end surface of the outer disk 12. Each vacuum chamber 1 is provided with an exhaust pipe 11. The center of the exhaust pipe 11 is coaxial with the center of the flip axis 9. One end of the exhaust pipe 11 is fixedly connected to the vacuum chamber 1, and the other end movably passes through the left turntable 32 and the inner disk 14. As the turntable rotates, the exhaust groove 18 and the exhaust groove are connected in sequence.

[0018] Ten chambers 24 are arranged side by side in the vacuum chamber of each vacuum chamber 1, and ten packaging bags can be placed at the same time. Corresponding to each chamber 24, a left machine clamp and a right machine clamp are provided. The left machine clamp and the right machine clamp perform synchronous opening and closing actions, which are controlled by an external machine clamp operating member. The machine clamp operating member includes a left vertical shaft 19, a right vertical shaft 23, a left crank 27, a right crank 25 and a connecting rod 26. The left vertical shaft 19 and the right vertical shaft 23 are rotatably arranged in the vacuum chamber 1, and the upper end of the left vertical shaft 19 is fixed. The movable clamp 20 connected to the left machine clamp has its lower end extending outward from the vacuum chamber 1 and fixedly connected to the left crank 27. The upper end of the right vertical shaft 23 is fixedly connected to the movable clamp 22 of the right machine clamp, and its lower end extending outward from the vacuum chamber 1 and fixedly connected to the right crank 25. The left and right cranks are connected by a connecting rod 26, and a roller is connected to the right crank 25. When the roller is pushed, the swing of the right crank drives the left crank to swing in the opposite direction through the connecting rod, so that the left and right vertical shafts rotate in opposite directions to drive the movable clamps of the left and right machine clamps to open or release the clamps synchronously. The heat sealing assembly includes a heat sealing iron 21 and a heat sealing pad. The heat sealing iron 21 is arranged to move forward and backward and is pushed by an external ironing cylinder 4. The ironing cylinder 4 is fixedly installed on the back of the vacuum chamber 1, and the heat sealing pad is arranged on the inner side of the cover plate 2.

[0019] The utility model works as follows: when working, the four vacuum chambers change their positions with the intermittent circular rotation of the turntable. Figure 1 Directly in front), the movable cover of the vacuum chamber is opened, and multiple packaging bags are placed in the vacuum chamber and clamped by the machine clamp assembly. Then the movable cover is closed, and the vacuum chamber rotates upward with the turntable. When the vacuum pipe of the vacuum chamber passes through the vacuum groove position, the vacuum pipe is connected to the vacuum groove, so the vacuum chamber is evacuated and the packaging bags are also evacuated. After the vacuum reaches a certain vacuum degree, the heat sealing assembly heat-seals the packaging bags. Then the vacuum pipe of the vacuum chamber passes through the exhaust groove, so that the air enters the vacuum chamber and becomes a normal pressure state. Then, at the bag lowering position ( Figure 1 Directly below), the movable cover of the vacuum chamber is opened, and the clamp assembly releases the clamping of the packaging bag, so the packaging bag will fall out of the vacuum chamber, and then the vacuum chamber reaches the bag loading position and repeats the above action.
