The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1-4This utility model discloses an automatic bag feeding device for a heavy bag packaging machine, comprising a base plate 1, a conveying assembly on the top right side of the base plate 1, the conveying assembly including two clamping frames 2, a conveyor belt 3 rotatably connected between the two clamping frames 2, rotating rollers 4 fixed on both sides of the inner wall of the conveyor belt 3, a drive motor 5 fixed on the left end of the front clamping frame 2, the output end of the drive motor 5 extending through to the inner side of the clamping frame 2 and fixedly connected to the rotating rollers 4, and a pressing assembly between the tops of the two clamping frames 2, the pressing assembly including a first top frame 6, the bottom ends of the first top frame 6 fixedly connected to the top of the clamping frame 2, and a first cylinder 7 fixed at the center of the top of the first top frame 6, the output end of the first cylinder 7 extending through to the inner side of the first top frame 6, and a pressing plate 8 fixedly connected to the output end of the first cylinder 7. In the prior art, the bag is supplied in a heavy bag packaging machine. Playing a crucial role, it not only provides the necessary packaging materials but also ensures the continuity of the packaging process and the smooth operation of automation. However, during the current special bag conveying process, the vacuum airflow inside the bag can easily cause it to bulge during transport, leading to instability. To address this issue, a bag supply assembly can be used to convey the individual supply bags 22, ensuring that the first individual supply bag 22 is in contact with the conveyor belt 3. When each individual supply bag 22 is being conveyed on the conveyor belt 3, the first cylinder 7 can be activated, causing the output end of the first cylinder 7 to push the pressing plate 8 downward, thereby pressing each individual supply bag 22 and ensuring that each individual supply bag 22 remains in a stable state during transport on the conveyor belt 3.

[0024] A bag supply assembly is provided on the top left side of the base plate 1. The bag supply assembly includes a front plate 9 and a rear plate 10. The bottom of the front plate 9 and the rear plate 10 are fixedly connected to the top of the base plate 1. The inner side of the front plate 9 and the rear plate 10 are provided with a patch 11. A rotating rod 12 is nested between the two patch 11. A general supply bag 13 is sleeved on the outside of the rotating rod 12. A driving member 14 is fixed to the front plate 9 and the outside. The output end of the driving member 14 passes through the inside of the front patch 11 and is fixedly connected to the rotating rod 12. The output end of the driving member 14 is rotatably connected to the front patch 11, so that the driving member 14 drives the rotating rod 12 and the general supply bag 13 to rotate, thereby facilitating the winding of the general supply bag 13.

[0025] A cutting assembly is provided on the top center side of the base plate 1. The cutting assembly includes a front frame 15 and a rear frame 16. The bottom of the front frame 15 and the rear frame 16 are fixedly connected to the top of the base plate 1. A cutting frame 17 is fixed between the top of the front frame 15 and the rear frame 16. A support plate 18 is slidably connected to the inside of the cutting frame 17. Multiple cutting parts 19 are fixed at the bottom of the support plate 18. A second cylinder 20 is fixed at the top of the cutting frame 17. The output end of the second cylinder 20 extends through to the inside of the cutting frame 17 and is fixedly connected to the top of the support plate 18, which facilitates scratching between adjacent individual supply bags 22.

[0026] Both plates 11 have through threaded holes 21 on their inner sides. The depth of the threaded holes 21 on both sides extends to the inner sides of the front plate 9 and the rear plate 10, thereby reinforcing the two plates 11. The overall supply bag 13 is composed of multiple individual supply bags 22. Multiple cutting parts 19 are located between adjacent individual supply bags 22, thereby enabling accurate scratching between adjacent individual supply bags 22.

[0027] Both ends of the bottom of the two clamping frames 2 are fixed with support plates 23. The bottom of the multiple support plates 23 is fixedly connected to the top of the base plate 1 to achieve the effect of reinforcing the bottom of the two clamping frames 2. The outer surface of the pressing plate 8 is smooth to avoid wear on the outer surface of the individual supply bag 22. The bottom surface of the base plate 1 has multiple anti-slip grooves 24 along the horizontal direction to achieve the effect of stabilizing the overall device.

[0028] Working principle: Reinforcing bolts are screwed into the threaded holes 21 on the inner sides of the two plates 11 to ensure their stability. Then, a rotating rod 12 and a bulk supply bag 13 are nested inside the two plates 11. At this point, the first individual supply bag 22 is brought into contact with the conveyor belt 3. Next, the drive unit 14 is activated, causing the rotating rod 12 and the bulk supply bag 13 to rotate, facilitating the winding of the bulk supply bag 13. Then, the conveyor belt 3 is started. When each individual supply bag 22 is conveyed on the conveyor belt 3, the first cylinder 7 can be activated. The output end of the first cylinder 7 pushes the pressing plate 8 downward, thereby pressing each individual supply bag 22. This ensures that each individual supply bag 22 is in a stable state when conveyed on the conveyor belt 3. When it is necessary to scratch adjacent individual supply bags 22, the second cylinder 20 can be activated to drive the support plate 18 and multiple cutting parts 19 downward, which facilitates scratching between adjacent individual supply bags 22 for subsequent use. Then, the conveyor belt 3 conveys the bag to the heavy bag packaging machine, which facilitates the subsequent operation of the heavy bag packaging machine.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
