[0019] Please refer to Figures 1 - 3 As shown, the present utility model provides a punching structure for a packaging bag sealing machine. The thicknesses of the first slider 9 and the second slider 11 are the same, and the heights of the first chute 10 and the second chute 12 are the same, so that the first chute 10 and the second chute 12 can respectively play a certain limiting role on the first slider 9 and the second slider 11. A pair of second electric telescopic rods 16 are provided on the bracket 2, the output end of the second electric telescopic rod 16 is fixedly connected with a pressure plate 17, a packaging bag sealing machine 19 is arranged at the upper end of the workbench 1, the packaging bag sealing machine 19 is located on one side of the bracket 2, a conveyor belt device 20 is arranged at the upper end of the workbench 1, and support legs 21 are fixedly connected to the lower end corners of the workbench 1.

[0020] During use, place the packaging bag on the upper end of the conveyor device 20. The conveyor device 20 will drive the packaging bag to move, and at the same time, the open end of the packaging bag will pass through the packaging bag sealing machine 19 for sealing. After the packaging bag is sealed, one end of it will move onto the cross plate 18, and then the conveyor device 20 is stopped from moving. Start the two second electric telescopic rods 16. The two second electric telescopic rods 16 drive the pressing plate 17 to move downward and press and fix it with the packaging bag, facilitating subsequent operations.

[0021] As a further implementation manner of this embodiment, as Figures 1 - 4 shown, a bracket 2 is fixedly connected to the upper end of the workbench 1. A cross plate 18 is fixedly connected to one side of the bracket 2, and a first electric telescopic rod 3 is fixedly connected to the upper end of the bracket 2. The output end of the first electric telescopic rod 3 is fixedly connected to a connecting plate 4. A first threaded rod 5 is fixedly connected to the lower end of the connecting plate 4. A threaded hole is opened at the upper end of the punch 6. Therefore, the first threaded rod 5 is threadedly connected to the punch 6. A through hole 7 is opened in the cross plate 18. A mold 8 is arranged in the through hole 7. A first slider 9 is fixedly connected to one side of the mold 8. A first chute 10 is opened in the cross plate 18 on one side of the through hole 7. The first slider 9 can slide in the first chute 10. A second slider 11 is fixedly connected to the other side of the mold 8. A second chute 12 is opened in the cross plate 18 on the other side of the through hole 7. The second slider 11 can slide in the second chute 12. A second threaded rod 13 is fixedly connected to one side of the second slider 11. A nut 14 is threadedly connected to the second threaded rod 13. A plurality of punching holes 15 of different sizes are opened in the mold 8.

[0022] During use, by rotating the punch 6, the punch 6 can be removed from the first threaded rod 5, and a punch 6 of a suitable size can be screwed onto the first threaded rod 5. At the same time, rotate the nut 14 so that one end of the nut 14 no longer abuts and fixes against the cross plate 18. At the same time, move the mold 8. During the movement of the mold 8, the first slider 9 slides in the first chute 10, and the second slider 11 moves in the second chute 12. When the punching hole 15 of a suitable size on the mold 8 is located directly below the punch 6, then rotate the nut 14 in the reverse direction so that the nut 14 abuts and fixes against the cross plate 18, thereby fixing the mold 8. Then start the first electric telescopic rod 3. The first electric telescopic rod 3 drives the connecting plate 4, the first threaded rod 5, and the punch 6 to move downward, and punching operations can be performed in cooperation with the punching holes 15. With this device, holes of different sizes can be punched in the packaging bag according to requirements, thus meeting different punching needs.

[0023] Specific working principle: During use, by rotating the punch 6, the punch 6 can be removed from the first threaded rod 5, and a punch 6 of appropriate size can be screwed onto the first threaded rod 5. At the same time, rotate the nut 14 so that one end of the nut 14 no longer abuts and fixes against the cross plate 18. Meanwhile, move the mold 8. During the movement of the mold 8, the first slider 9 slides in the first chute 10, and the second slider 11 moves in the second chute 12. When the punching hole 15 of appropriate size on the mold 8 is directly below the punch 6, rotate the nut 14 in the reverse direction so that the nut 14 abuts and fixes against the cross plate 18, thereby fixing the mold 8. Then place the packaging bag on the upper end of the conveyor device 20 and start the conveyor device 20. The conveyor device 20 will drive the packaging bag to move, and at the same time, make the open end of the packaging bag pass through the packaging bag sealing machine 19 for sealing treatment. After the packaging bag is sealed, one end of it will move onto the cross plate 18. Then stop the conveyor device 20 from moving, and at the same time start the two second electric telescopic rods 16. The two second electric telescopic rods 16 drive the pressing plate 17 to move downward and press and fix the packaging bag. Then start the first electric telescopic rod 3. The first electric telescopic rod 3 drives the connecting plate 4, the first threaded rod 5, and the punch 6 to move downward, and can perform a punching operation in cooperation with the punching hole 15. With this device, holes of different sizes can be punched in the packaging bag according to requirements, so as to meet different punching needs.
