[0025] Specifically, the fixed frame 3 plays a role in connecting and fixing the various components of the mechanism, thereby ensuring the stability of the mechanism during use. The rotation of the first servo motor 1 will drive the first synchronous wheel 2 to rotate, and the rotation of the first synchronous wheel 2 will drive the first synchronous belt 4 to rotate. The power is transmitted through the first synchronous belt 4, thereby driving the two first synchronous wheels 2 to rotate at the same time, thereby driving the nickel-plated roller 9 to rotate. The rotation of the second servo motor 17 will drive the second synchronous wheel 6 to rotate, and the rotation of the second synchronous wheel 6 will drive the second synchronous belt 12 to rotate. When the second synchronous belt 12 rotates, it will drive the linear guide 15 to move laterally. The output ends of the first cylinder 5 are connected to aluminum plates, and the second cylinder 16 drives the movable frame 13 and the rubber-coated roller 8 to move. The friction generated by the extrusion of the rubber-coated roller 8 and the nickel-plated roller 9 pushes the bag forward, and the head of the bag can be sensed by the mini diffuse reflection photoelectric 10.

[0026] Reference Figure 1 、 Figure 2 The output end of the second cylinder 16 is fixedly provided with a mobile frame 13, and the lower end of the mobile frame 13 is rotatably provided with a rubber-coated roller 8, and the lower end of the middle part of the fixed frame 3 is rotatably provided with a nickel-plated roller 9, and one side of the nickel-plated roller 9 is fixedly connected to one of the two first synchronous wheels 2. A linear guide rail 15 is slidingly provided on the upper end of the middle part of the front of the fixed frame 3, and a diamond cutter 7 is fixedly provided on the lower end of the linear guide rail 15.

[0027] Specifically, the movable frame 13 can drive the rubber-coated roller 8 to move, and the linear guide rail 15 can drive the diamond cutter 7 to move, thereby cutting the bag. The connecting plate 14 and the connecting frame 11 are used in conjunction to install the mechanism on the guide rail of the packaging machine for sanitary napkins or menstrual pants.

[0028] Working principle: When in use, the mechanism is first installed on the guide rail of the packaging machine for sanitary napkins or menstrual pants through the provided connecting frame 11 and connecting plate 14, and the overall mechanism can be changed accordingly according to the width of the bag. After that, the bag-making factory makes a certain number of bags into roll film, and the operator passes the head end of the roll film through the gap between the rubber-coated roller 8 and the nickel-plated roller 9. The rubber-coated roller 8 is controlled by the second cylinder 16. After the film passes through, the cylinder extends to press the film. At this time, the first servo motor 1 is controlled by the program to drive the first synchronous belt 4, and the first The synchronous wheel 2 rotates the nickel-plated roller 9 connected to the first synchronous wheel 2, and the friction generated by the extrusion of the rubber-coated roller 8 and the nickel-plated roller 9 pushes the bag forward. When it reaches the set distance, the mini diffuse reflection photoelectric 10 senses the head of the bag, and the program controls the first servo motor 1 to stop. At the same time, the two first cylinders 5 below drive the aluminum plate downward to press the bag, and drive the second synchronous wheel 6 and the second synchronous belt 12 through the second servo motor 17, and control the diamond cutter 7 on the linear guide rail 15 to move horizontally to cut the bag, and then repeat the cycle.
