[0025] EMBODIMENT

[0026] Please refer to Figures 1-3 A plastic container bag cutting device, including workbench 1, four supporting legs 2 are fixedly installed on the bottom end of workbench 1 in symmetry, two fixed plates 3 are fixedly installed on workbench 1 in symmetry, one of fixed plates 3 is fixedly installed with first motor 4, and placing roller 5 is fixedly installed on the output end of first motor 4.

[0027] Please refer to Figures 1-3 The cutting mechanism is arranged on workbench 1, and the cutting mechanism includes U-shaped plate 6, U-shaped plate 6 is fixedly installed on workbench 1, two first electric push rods 7 are fixedly installed on U-shaped plate 6 in symmetry, two first electric push rods 7 are connected through connecting plate 8, and cutting knife 9 is arranged on connecting plate 8,

[0028] Please refer to Figures 1-3The cutting scissors 9 perform auxiliary cutting operations through two auxiliary mechanisms. One of the auxiliary mechanisms includes a pressure plate 21, on which two telescopic columns 22 are symmetrically fixedly installed. Both telescopic columns 22 are fixedly connected to the connecting plate 8. Each telescopic column 22 is fitted with a spring 23. The two ends of the two springs 23 are fixedly connected to the pressure plate 21 and the connecting plate 8, respectively. When the cutting scissors 9 cuts, the pressure plate 21 limits the position of the container bag, thereby preventing the container bag from shifting during cutting.

[0029] Please see Figures 1-4 The workbench 1 is equipped with a transmission mechanism, which includes a first transmission roller 10. A placement groove is provided on the workbench 1, and the first transmission roller 10 is rotatably connected to the placement groove. Synchronous pulleys 11 are fixedly mounted on both the first transmission roller 10 and the placement roller 5, and the two synchronous pulleys 11 are connected by a belt. A first mounting plate 12 is fixedly mounted on the workbench 1, and two second electric push rods 13 are symmetrically fixedly mounted on the first mounting plate 12. The two second electric push rods 13 are connected by a second mounting bracket 14, and a second transmission roller 15 is rotatably mounted on the second mounting bracket 14. Gears 1 are fixedly mounted on both the second transmission roller 15 and the first transmission roller 10. 6. The two gears 16 mesh. The meshing teeth of the two gears 16 are relatively long, so they can still mesh even when making fine adjustments. Place the container bag to be cut on the placement roller 5. Adjust the height of the second transmission roller 15 according to the thickness of the container bag. After fine adjustment, the two gears 16 can still mesh. Pass one end of the container bag between the first transmission roller 10 and the second transmission roller 15 and place it at the bottom of the cutting shears 9. The cutting shears 9 are driven by the two first electric push rods 7 to perform the cutting operation. The cutting shears 9 perform the cutting operation through the auxiliary mechanism. The container bag is driven by the cooperation of the first transmission roller 10 and the second transmission roller 15.

[0030] Please see Figures 1-4 The cut container bags are conveyed by a conveying mechanism, which includes two rotating shafts 18. A working groove is provided on the workbench 1, and both rotating shafts 18 are rotatably connected to the working groove. A second motor 17 is fixedly installed on the outer wall of the workbench 1. The output end of the second motor 17 is fixedly connected to one end of one of the rotating shafts 18. Conveying rollers 19 are fixedly installed on both rotating shafts 18. The two conveying rollers 19 are tensioned and connected by a conveyor belt 20. By starting the second motor 17, the second motor 17 provides power to drive one of the rotating shafts 18 to rotate. With the cooperation of the conveyor belt 20, the two rotating shafts 18 and the two conveying rollers 19 rotate synchronously, and the cut container bags are conveyed by the conveyor belt 20.

[0031] Please see Figures 1-3 It should also be noted that the conveyor belt 20 is equipped with friction pads 24, which increases the friction and makes the container bag more stable.

[0032] Please see Figures 1-3 A guide plate 25 is fixedly installed on the workbench 1, which guides the container bags during operation.

[0033] In summary, when using this plastic bulk bag cutting device, the bulk bag to be cut is placed on the placement roller 5. Depending on the thickness of the bulk bag, two second electric push rods 13 are activated, which drive the second mounting frame 14 and the second transmission roller 15 to move. The height of the second transmission roller 15 can be adjusted according to actual needs. Since the thickness difference of the bulk bags is small, the meshing teeth of the two gears 16 are relatively large. After fine adjustment, the two gears 16 still mesh. The first motor 4 is activated. This motor is a commercially available device known to those skilled in the art; we are only using it practically without making structural or functional improvements, which will not be elaborated upon here. The motor is equipped with a matching control switch, the installation position of which is selected according to actual practical needs for easy operation. The first motor 4 provides power to drive the placement roller 5 to rotate, thereby moving one end of the bulk bag and cutting the bulk bag. One end passes between the first drive roller 10 and the second drive roller 15 and is placed at the bottom of the cutting shears 9. By activating the two first electric push rods 7, the cutting shears 9 are driven to perform the cutting operation. During the cutting operation, the cutting shears 9 use two pressure plates 21 to press and limit the container bag, thereby preventing the container bag from shifting during the cutting process. While the placement roller 5 rotates, the first drive roller 10 rotates through the cooperation of two synchronous wheels 11. The rotation of the first drive roller 10 drives one of the gears 16 to rotate. Through the meshing of the two gears 16, the second drive roller 15 is driven to rotate. The container bag is transported through the cooperation of the first drive roller 10 and the second drive roller 15. The second motor 17 is activated, and the second motor 17 provides power to drive one of the rotating shafts 18 to rotate. Through the cooperation of the conveyor belt 20, the two rotating shafts 18 and the two conveyor rollers 19 rotate synchronously. The cut container bag is transported through the conveyor belt 20.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
