There are two groups of them, which are installed at equal distances on both sides of the cutter 12. The servo motor 3 starts after receiving the command from the control panel 17, driving the screw rod 4 to rotate. The screw rod 4 is threadedly connected to the threaded hole on the side of the sliding seat 6, so that the sliding seat 6 slides on the guide rod 5. This action adjusts the position of the lifting plate 9 and the cutter 12 to adapt to bags of different heights. At the same time, the cylinder 7 starts to work, pushing the lifting plate 9 up and down through the telescopic rod 8 to further adjust the height of the cutter 12. When the bag is transferred to the bottom of the cutter 12, the walking wheels 11 provide support and guidance on both sides to ensure that the bag remains stable during the cold cutting process. The control panel 17 issues a command, the cold cutting device 2 starts to work, and the cutter 12 falls quickly to cold cut the bag. After the cold cutting is completed, the cutter 12 is reset under the drive of the cylinder 7 and waits for the next operation.

[0020] Reference Figure 1 and Figure 2A side baffle 13 is fixedly connected to the top of the base 1, an electric push rod 14 is fixedly connected to one side of the side baffle 13, a guide push plate 15 is fixedly connected to one end of the electric push rod 14, a movable groove 151 is opened on one side of the guide push plate 15, a lifting screw 152 is arranged inside the movable groove 151, a lifting block 153 is screwed to one end of the lifting screw 152, a movable rod 154 is movably connected to one end of the lifting block 153, a roller 156 is fixedly connected to one end of the movable rod, a spring 155 is installed on the movable rod 154 between the lifting block 153 and the roller 156, a rotating handle 157 is arranged on the top of the guide push plate 15, when it is necessary to adjust or push the bag, the electric push rod 14 starts to work after receiving the command of the control panel 17, and the telescopic end of the electric push rod 14 pushes the guide push plate 15 along the side baffle The plate 13 moves, thereby pushing or positioning the bag. A lifting screw 152 is arranged inside the movable groove 151 on the guide push plate 15. One end of the lifting screw 152 is screwed to the lifting block 153. By adjusting the rotation of the lifting screw 152, the up and down movement of the lifting block 153 in the movable groove 151 can be accurately controlled. The lifting block 153 is connected to the roller 156 through the movable rod 154. The movable rod 154 is partially installed with a spring 155. The function of the spring 155 is to provide a certain buffer and stability when the lifting block 153 moves, to ensure the smooth contact between the roller 156 and the bag. The roller 156 is the part of the guide push plate auxiliary device that directly contacts the bag. When the guide push plate 15 moves, the roller 156 rolls along the surface of the bag, reducing the friction between the bag and the bag, making the pushing process smoother.

[0021] Reference Figure 1 and Figure 4 A conveyor belt 16 is provided above the base 1, and a control panel 17 is electrically connected to one side of the cold cutting device 2. During the whole process, the conveyor belt 16 keeps running to transport new bags to the bottom of the cold cutting device 2 for cold cutting.

[0022] The working principle of the utility model is as follows: when the production line starts to operate, the conveyor belt 16 starts to run, and the bags to be cold-cut are transported to the bottom of the cold-cutting device 2. The servo motor 3, the cylinder 7 and the electric push rod 14 are all in a standby state, waiting for the command issued by the control panel 17. When the bags are transmitted to the bottom of the cold-cutting device 2 through the conveyor belt 16, the two groups of side baffles 13 and the guide push plate 15 are extended and retracted by the four groups of electric push rods 14 to form an adjustable guide structure. When the bag needs to be adjusted, the electric push rod 14 starts to work after receiving the command of the control panel 17, and the telescopic end of the electric push rod 14 pushes the guide push plate 15 to move, thereby realizing the positioning of the bag. A lifting screw 152 is provided inside the movable groove 151 on the guide push plate 15. One end of the lifting screw 152 is screwed to the lifting block 153. By adjusting the rotation of the lifting screw 152, the lifting block 153 can be accurately controlled to move up and down in the movable groove 151. The lifting block 153 is connected to the roller 156 through the movable rod 154. The movable rod 154 is partially installed with a spring 155. The function of the spring 155 is to provide a certain buffer and stability when the lifting block 153 moves, ensuring that the contact between the roller 156 and the bag is stable. The roller 156 is the part of the guide push plate auxiliary device that directly contacts the bag. When the guide push plate 15 moves, the roller 156 56 rolls along the surface of the bag, reducing the friction between the bag and the bag, making the pushing process smoother. This guide structure ensures that the bag keeps moving in a straight line during the transmission process to prevent deviation. The position of the guide push plate 15 can be adjusted through the control panel 17 to adapt to bags of different specifications and shapes. After receiving the command of the control panel 17, the servo motor 3 starts to drive the screw rod 4 to rotate. The screw rod 4 is threadedly connected with the threaded hole on the side of the sliding seat 6, so that the sliding seat 6 slides on the guide rod 5. This action adjusts the position of the lifting plate 9 and the cutter 12 to adapt to bags of different heights. At the same time, the cylinder 7 starts to work and pushes the lifting plate through the telescopic rod 8. 9 moves up and down to further adjust the height of the cutter 12. When the bag is transferred to the bottom of the cutter 12, the walking wheels 11 provide support and guidance on both sides to ensure that the bag remains stable during the cold cutting process. The control panel 17 issues an instruction, the cold cutting device 2 starts working, and the cutter 12 falls quickly to cold cut the bag. After the cold cutting is completed, the cutter 12 is reset under the drive of the cylinder 7 and waits for the next operation. During the whole process, the conveyor belt 16 continues to operate to transport new bags to the bottom of the cold cutting device 2 for cold cutting. The servo motor 3, the cylinder 7 and the electric push rod 14 are adjusted accordingly according to the instructions of the control panel 17 to adapt to bags of different specifications and shapes.
