[0026] Embodiment 1

[0027] Refer to Figures 1 - 5, a vacuum packaging machine, comprising a support frame 1. Both ends of the outer side of the support frame 1 are provided with flipping grooves 2. Two film rotating rods 3 are rotatably connected to the top end of the support frame 1. A film roll 4 is sleeved on the outer side of the film rotating rod 3. Two clamping buffer chutes 5 are provided at both ends of the inner side of the support frame 1. Clamping sliders 6 are slidably embedded in the inner sides of the clamping buffer chutes 5. One end of each clamping slider 6 is connected with a buffer spring 7 inside the clamping buffer chute 5. One end of each clamping slider 6 is rotatably connected with a sealing edge roller 8 through a connecting rod. A heating cover 9 is sleeved on the outer side of the connecting rod for fixing the sealing edge roller 8. A sliding rod 11 is welded to the outer side of one end of the heating cover 9. One end of each of several sliding rods 11 is slidably embedded in the inner side of a stability maintaining seat 10. The stability maintaining seats 10 are welded to both ends of the inner side of the support frame 1 through brackets. A heater 12 is installed on the top end of the stability maintaining seat 10 through a base. In order to seal the film, a parallel connecting rod 13 is welded between the two sealing edge rollers 8 through a connecting rod. Several heating resistance wires 14 are connected to the inner side of the heating cover 9. Two bottom sealing chutes 15 are provided at the bottom ends of the clamping buffer chutes 5 at both ends of the inner side of the support frame 1. A bottom sealing clamping plate 16 is slidably embedded in the inner sides of the two opposite bottom sealing chutes 15. A sealing clamping plate 17 is welded to the bottom end of the bottom sealing clamping plate 16. A top sealing clamping plate 22 is welded to the bottom end of the sealing clamping plate 17. The power output ends of the heater 12 are respectively connected to the power input ends of several heating resistance wires 14, the bottom sealing clamping plate 16 and the top sealing clamping plate 22. Clamping cylinders 18 are installed on both ends of the inner side of the support frame 1 through bases. Two stabilizing blocks 21 are welded to the bottom end of the bottom sealing chute 15 at one end of the inner side of the support frame 1. A rotating rod 20 is rotatably connected to the inner side of each of the two stabilizing blocks 21. A storage bin 19 is welded between the two rotating rods 20. In order to perform top sealing and vacuum pumping operations on the package, a vacuum pump 29 is installed on the outer side of one end of the storage bin 19 through a base. Top sealing chutes 30 are penetrated through both ends of the outer side of the storage bin 19. Several return springs 28 are connected to the outer side of the flipping groove 2 at one end of the support frame 1 through brackets. In order to be able to reset the flipped storage bin 19, one end of each of several return springs 28 is connected to the outer surface of one end of the storage bin 19. The sealing clamping plate 17 and the top sealing clamping plate 22 are both slidably embedded in the inner sides of the top sealing chutes 30 penetrated through both ends of the storage bin 19. A cutting knife 24 is welded to the top end of the sealing clamping plate 17 at the bottom end of the bottom sealing clamping plate 16. In order to cut off the film that seals the side and the ground, the clamping ends of the bottom sealing clamping plate 16, the sealing clamping plate 17, the top sealing clamping plate 22 and the cutting knife 24 are on the same vertical line. The extending end of the clamping cylinder 18 is connected to the outer side of one end of the bottom sealing clamping plate 16. A sealing inclined plate 23 is welded to the outer side of one end of the top sealing clamping plate 22. In order to increase the sealing performance, a feeding bin 25 is connected to the middle of the top end of the support frame 1. A feeding pump 26 is installed on the top end of the feeding bin 25 through a base. The feeding end of the feeding pump 26 is connected with a hose 27. In order to achieve feeding.

[0028] Working principle: First, the operator sleevs two film rolls 4 on the outside of the film rotating rod 3, then places the two film rotating rods 3 on the top of the support frame 1. Subsequently, the operator simultaneously pulls the films at one end of the two film rolls 4 and pulls the films downward along the outer surface of the edge sealing roller 8. Then the operator starts the heater 12. At this time, the heater 12 will energize the power input ends of the heating resistance wire 14, the bottom sealing clamping plate 16 and the top sealing clamping plate 22 connected to its power output end. During this period, the heating resistance wire 14 will heat the outer surface of the edge sealing roller 8 which is also rotatably connected inside the heating cover 9. Then pull the two films downward again. During this period, the two edge sealing rollers 8 will thermoplast the edges of the film clamped in the middle, so that the two sides of the two films are closed. Then start the clamping cylinder 18. At this time, the clamping cylinder 18 will push the bottom sealing clamping plate 16 connected to its extending end to clamp, and at the same time, thermoplastically seal the bottom ends of the two clamped films;

[0029] Then the operator starts the feeding pump 26. At this time, the feeding pump 26 will extract materials from the outside through the hose 27 connected to its material input end and pour them into the feeding bin 25 through its output end. Then it enters the film belt with thermoplastically sealed edges and bottom through the discharge end of the feeding bin 25. Then the operator controls the clamping cylinder 18 again to make it pull the bottom sealing clamping plate 16 connected to its extending end to open. At this time, the film bag filled with materials will be driven downward by the weight of the materials inside because there is no support, and finally enter the storage bin 19. At this time, the storage bin 19 will not turn over because the uncut film will limit the storage bin 19. Then the operator performs the same operation again and starts the clamping cylinder 18. At this time, the clamping cylinder 18 will push the bottom sealing clamping plate 16 connected to its extending end to clamp. During this period, the edge sealing roller 8 will continue to seal the two sides of the downward moving film, and the cutting knife 24 welded to the bottom end of the bottom sealing clamping plate 16;

[0030] It will also clamp along with it and cut off the top end of the film filled with materials. During this period, the sealing clamping plate 17 welded to the bottom end of the bottom sealing clamping plate 16 will drive the top sealing clamping plate 22 welded to its bottom end to clamp and slide inside the top sealing chute 30 opened at both ends of the storage bin 19. And the sealing inclined plate 23 welded to the outer side of one end of the top sealing clamping plate 22 can seal the outside of the top sealing chute 30 after the two top sealing clamping plates 22 are completely closed. The two sealing clamping plates 17 will seal the top end of the storage bin 19. At this time, the vacuum pump 29 installed at one end of the storage bin 19 is started through the control terminal. At this time, the vacuum pump 29 will evacuate the inside of the sealed storage bin 19, and the packaging bag will also be in a vacuum state. Subsequently, the operator energizes the top sealing clamping plate 22 through the heater 12, so that the two top sealing clamping plates 22 heat-seal the top end of the packaging bag clamped by them. Then the vacuum pump 29 is turned off. Then the clamping and edge-sealing mechanism is pulled apart by the clamping cylinder 18. When the sealing clamping plate 17 and the top sealing clamping plate 22 are disengaged from the top sealing chute 30, the storage bin 19 will be unstable due to the rotating rod 20 at its bottom on one side, driving the storage bin 19 to turn over. After the storage bin 19 turns over to a certain angle, the packaging bag inside it will be poured out. And the return spring 28 installed outside one end of the support frame 1 through the bracket will drive the storage bin 19 to return to the upright position, waiting for the next packaging bag that moves down due to gravity and has no cut-off and sealed top to enter it. In this way, by repeating the cycle, the packaging operation can be quickly packed.

[0031] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
