[0044] Example: The main unit of this device consists of: a film unwinding mechanism, a shaping, sealing and cutting mechanism, a bag receiving and buffering mechanism, a circular conveying mechanism, a circular pre-shaping mechanism, a vacuum sealing mechanism, a bag clamping and lifting mechanism, a tail cutting mechanism, and a finished product conveying section.

[0045] The packaging material enters the sealing area via the unwinding guide roller, is shaped and longitudinally sealed by the shaping and sealing mechanism, is then filled with material and conveyed by the circular conveyor mechanism to the vacuum sealing station for vacuum sealing, and finally the vacuum product is transferred by the bag clamping and lifting mechanism to the output by the conveyor mechanism.

[0046] The film unwinding mechanism is located at the rear of the machine and consists of an unwinding frame 51, an unwinding shaft 52, a guide roller 53, a floating guide roller 54, and a splicing platform assembly 55. The unwinding frame 51 is equipped with an unwinding shaft 52, which is connected to a drive motor. The film roll is placed on the unwinding shaft 52. After passing through the guide roller 53, the splicing platform assembly 55, and the floating guide roller 54, the film enters the sealing area. The floating guide roller 54 can be adjusted in height by tightening screws.

[0047] The shaping, sealing, and cross-cutting mechanism: Driven by synchronous belts A12 on both sides, the packaging material moves downwards. During this movement, it is shaped by the shaping tube 14 and longitudinally sealed by the longitudinal sealing mechanism 13. After sealing, cylinder A11 extends, simultaneously moving the longitudinal sealing assembly outwards, creating space between the packaging material and the sealing body for further downward movement. Servo motor A118 is the main power source, driving gear B117 connected to gear A116, and via connecting rod A119, moving the linear bearing housed in the bearing housing outwards on guide rod A15. Simultaneously, cylinder B18 moves inward towards the packaging material until the sealing bodies 19 mounted on the two bearing seats B120 overlap. Each side of the sealing body is equipped with a bag-clamping and fixing device 122. A fixing block 113 is connected to a sliding plate 114, which in turn is connected to a connecting rod B123. One side of the connecting rod is connected to a hinge seat 115 and fixed to a support 124. One side of the sliding plate is connected to the bearing seat via a clamping plate 17. As the bearing seat moves, the guide rod B121 also slides within the bearing seat A112, driving the bag-clamping and fixing plate 110 inward, thus fixing the bag in a specific position. A section in the middle of the sealing body remains unsealed, reserved for vacuuming. A slitting blade is installed in the middle to cut the packaging material during sealing, creating individual bags.

[0048] Bag receiving and buffering mechanism: After being laterally cut, the bags fall into the buffer hopper 25. Once the bags are in the hopper, the connecting rod of cylinder C24 moves outward, causing the shaping plate 29 to move as well. Simultaneously, cylinder D214 also moves outward, causing the hopper mounting plate 215 to move as well. At the same time, coupling 21 rotates, and the connected guide rod C211 and crank connecting rod 212 also move accordingly, causing the guide plate 213 to move outward. The servo motor B22 provides the driving force, rotating and driving pulley A210 to rotate. The synchronous belt B28 then rotates, causing the fixed upright plate 26, connected to the guide rail A23 via a slider, to move and connect to the hopper mounting plate via connecting seat 27. This movement also allows space between the hoppers for the bags to pass through.

[0049] Circular conveyor mechanism: The material falls from the buffer bin into the box 31 in the circular conveyor mechanism. The servo motor is used as the main power source and is connected to the sprocket through the transmission shaft, which drives the sprocket to rotate and thus makes the entire mechanism move.

[0050] The pre-shaping mechanism on the circular conveyor belt: The bag is conveyed to this station via the circular conveyor belt. Cylinder F61 extends, causing cylinder connecting plate B62 and pressure plate to move forward simultaneously, bringing the two pressure plates 610 and the squeezing plate 63 on one side into contact with and clamping the bag. Simultaneously, cylinder G67 extends, and guide post 66, fixed in bearing seat D68, moves upward, causing the clamped bag to move upward as well. A linear bearing B69 is installed inside the bearing seat. The guide rod of cylinder connecting plate B62 retracts, causing the bag to fall into the box compartment, and the cylinder clamping the bag releases.

[0051] Vacuum sealing mechanism: The vacuum sealing mechanism mainly consists of two parts: a movable vacuum chamber 71 and a vacuum seal 72. The box is transported to the vacuum sealing mechanism by a circular conveyor mechanism. The guide rod of cylinder 76 retracts, which causes the vacuum box shell 75 to move towards the vacuum sealing mechanism until it coincides with the vacuum box fixing plate 710, thereby bringing the cavity into a vacuum state.

[0052] Bag clamping and lifting device: The box compartment is conveyed to the bag clamping and lifting device via a circular conveyor. The guide rod of the tail-cutting cylinder 411 extends, causing the movable blade 418 to move forward until it coincides with the fixed blade 417, cutting off the excess part of the bag tail and clamping the bag tail. After the tail-cutting action is completed, the guide rod of the push plate cylinder 416 extends, causing the cylinder connecting plate A415, bearing seat C49, and other related components to move upward on the guide shaft 47. When it moves to a certain position, the guide rod of the cylinder E410 extends. This causes the entire lifting and clamping mechanism to move forward to above the conveying mechanism. At this time, the guide rod of the tail-cutting cylinder retracts, and the finished bag naturally falls onto the conveying mechanism.

[0053] Conveying mechanism: The servo motor D81 rotates, which in turn causes the conveyor belt 83 to move continuously. The finished bags that fall on the conveyor belt are transported to the outside of the equipment as the conveyor belt moves.
