[0028] like Figure 1-Figure 6 As shown, a device for automatically cutting PV packaging tape for sheet cigarette paper box packaging comprises a supporting device 1, a cutting device 2 and a grasping mechanism 3, wherein the supporting device 1 is used to place a cigarette box 8, a notch 11 for avoiding the cutting device 2 is arranged in the middle of the supporting device 1, and the cutting device 2 comprises a linear module 21, a movable bracket 22 is installed at the linear moving end of the linear module 21, a baffle 23 is fixedly connected to the movable bracket 22, a guide rod 24 is fixedly connected to the baffle 23, and the guide rod 24 extends in a direction toward the cigarette box 8 and the guide rod 24 is away from the baffle 23. The end is used to abut against the bottom surface of the cigarette box 8, and the end of the guide rod 24 away from the stop rod 23 is bent upward so that the guide rod 24 is inserted into the packaging belt 9 at the bottom of the cigarette box 8 and the packaging belt 9 is lifted downward to separate from the bottom surface of the cigarette box 8 when the linear module 21 is driven to move; the mobile bracket 22 is equipped with a cutting knife 25 for cutting the packaging belt 9, and the cutting knife 25 is located on the side of the stop rod 23 close to the packaging belt 9 to cut the packaging belt 9 that penetrates to the bottom of the guide rod 24. The grabbing mechanism 3 is located above the support device 1 and is used to grab and remove the cut packaging belt 9 on the cigarette box 8. Specifically, the linear module 21 is a driving unit for driving the mobile bracket 22 to move linearly, and can adopt one of the synchronous belt type, ball screw type, and linear motor type linear modules 21 in the prior art.

[0029] By adopting the above technical solution, the linear module 21 drives the movable bracket 22 to move horizontally, so that the guide rod 24 moves toward the cigarette box 8 and is inserted into the packaging belt 9, and the packaging belt 9 is supported downward by the guide rod 24 to separate from the bottom surface of the cigarette box 8, so that it is convenient for the cutting knife 25 to cut the packaging belt 9 without damaging the bottom surface of the cigarette box 8, thereby realizing the cutting of the packaging belt 9 on the cigarette box 8 from the bottom, and then the packaging belt 9 is grabbed and removed from the top of the cigarette box 8 by the grabbing mechanism 3, thereby realizing the automatic cutting and removal of the packaging belt 9 on the cigarette box 8.

[0030] Specifically, a lifting cylinder 26 is installed on the movable bracket 22, and the cutting knife 25 is installed at the end of the piston rod of the lifting cylinder 26. The lifting cylinder 26 pushes the cutting knife 25 out so that the upper edge of the cutting knife 25 passes through the guide rod 24, so that the packaging belt 9 can be cut when cutting the packaging belt 9, and is retracted to the bottom of the guide rod 24 when not cutting, so as to prevent the upper edge of the cutting knife 25 from coming out.

[0031] Specifically, the cutting knife 25 is one of a circular knife, a diamond-shaped knife, a triangular knife or a rectangular knife. Specifically, when the cutting knife 25 is a circular knife, it can be rotatably connected or fixedly connected to the piston rod end of the lifting cylinder 26 to cut by a rotary motion or a linear motion. When the cutting knife 25 is a diamond-shaped knife, a triangular knife or a rectangular knife, it is fixed to the piston rod end of the lifting cylinder 26.

[0032] Specifically, a cutting slit 241 is provided in the middle of the guide rod 24, and the cutting knife 25 is located in the cutting slit 241 during cutting. By providing the cutting slit 241, the cutting knife 25 is located in the cutting slit 241, and during cutting, the guide rods 24 are provided on both sides of the cutting knife 25 to support the packaging belt 9, so that the cutting knife 25 can cut the packaging belt 9 easily.

[0033] Specifically, the movable bracket 22 is provided with an elastic touch plate 27, which is located between the blocking rod 23 and the cutting knife 25. The blocking rod 23 is provided with a proximity switch sensor 28. The movement of the touch plate 27 triggers the change of the electrical signal of the proximity switch sensor 28 so that the proximity switch sensor 28 recognizes the movement of the touch plate 27. When the cutting knife 25 fails to cut the packaging belt 9 on the cigarette box 8, the packaging belt 9 passes over the cutting knife 25 and contacts the touch plate 27, so that the touch plate 27 moves and is then recognized by the proximity switch sensor 28, so that the system can re-execute the cutting operation. The touch plate 27 is elastic so that it can automatically reset when the external force of the trigger is removed.

[0034] Specifically, the grabbing mechanism 3 includes a moving block 31 and a grabbing hook 32 hinged on the moving block 31, and the grabbing hook 32 includes a support plate 321 and a hook claw 322 fixed at the lower end of the support plate 321, and a concave cavity 323 for accommodating the packaging belt 9 is arranged between the hook claw 322 and the support plate 321, and the opening of the concave cavity 323 faces the packaging belt 9 to be grabbed, and the end of the hook claw 322 away from the support plate 321 is used to abut against the upper surface of the cigarette box 8 to hook the packaging belt 9 into the concave cavity 323; an elastic element 33 is installed on the moving block 31, and one end of the elastic element 33 abuts against the side of the support plate 321 away from the hook claw 322 to push the hook claw 322 toward the upper surface of the cigarette box 8. During operation, the moving block 31 drives the grab hook 32 to move toward the cigarette box 8, and the grab hook 32 is pushed out toward the cigarette box 8 by the elastic element 33, so that the lower end of the hook claw 322 keeps in contact with the upper surface of the cigarette box 8, and as the moving block 31 moves, the grab hook 32 is driven to hook the packaging belt 9 on the cigarette box 8 into the concave cavity 323, so as to grab and remove the cut packaging belt 9 from the cigarette box 8.

[0035] Specifically, the support plate 321 is hingedly connected with a limiting plate 34, the lower end of which overlaps the hook 322, and the angle between the limiting plate 34 and the hook 322 on the side close to the concave cavity 323 is greater than 90 degrees. By providing the limiting plate 34, when grabbing the packaging belt 9, the packaging belt 9 abuts against the limiting plate 34 so that the limiting plate 34 swings toward the concave cavity 323. After the packaging belt 9 passes over the limiting plate 34 and falls into the concave cavity 323, the limiting plate 34 is reset to overlap the hook 322 under the action of gravity, thereby limiting the packaging belt 9 in the concave cavity 323 to prevent the packaging belt 9 from being unhooked from the concave cavity 323.

[0036] Specifically, a truss manipulator 4 is arranged above the support device 1, and the moving block 31 is installed at the end of the truss manipulator 4. The truss manipulator 4 drives the moving block 31 to move to hook the packaging belt 9 on the cigarette box 8. The truss manipulator 4 drives the moving block 31 to move, so that the moving block 31 can be driven to move horizontally along the upper surface of the cigarette box 8 to hook the packaging belt 9, and the PV packaging belt 9 on the surface of the cigarette box 8 is collected together by the gripper, and then the truss manipulator 4 is lifted up to bring the packaging belt 9 to the recycling area for centralized processing.

[0037] Specifically, the elastic element 33 is a spring.

[0038] Specifically, the support device 1 is a double-row roller conveyor, and a gap 11 is provided between the double-row roller conveyors to avoid the cutting device 2. The support device 1 is set as a double-row roller conveyor, which is convenient for the cigarette box 8 to be sent to the cutting and packaging belt 9 station and to be moved out of the station. Specifically, the double-row roller conveyor is provided with a fixing mechanism to fix the cigarette box 8 on the cutting and packaging belt 9 station.

[0039] The parts not involved in this technical solution can be implemented by using existing technologies.
