[0025] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0028] like Figures 1-6 As shown, a device for automatically cutting PV packaging tape for sheet cigarette carton packaging includes a supporting device 1, a cutting device 2 and a gripping mechanism 3. The supporting device 1 is used to place a cigarette box 8. A notch 11 is provided in the middle of the supporting device 1 to avoid the cutting device 2. The cutting device 2 includes a linear module 21. A movable bracket 22 is installed at the linear movable 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. The guide rod 24 extends in the 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. The end of the guide rod 24 away from the stop rod 23 is bent upward so that when the linear module 21 is driven to move, 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 and separated from the bottom surface of the cigarette box 8. The movable bracket 22 is equipped with a cutting knife 25 for cutting the packaging belt 9. 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 has penetrated to the bottom of the guide rod 24. The grasping mechanism 3 is located above the support device 1 and is used to grasp and remove the cut packaging belt 9 from the cigarette box 8. Specifically, the linear module 21 is a driving unit that drives the movable bracket 22 to move linearly. It can adopt one of the linear modules 21 of synchronous belt type, ball screw type, and linear motor type 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. The guide rod 24 supports the packaging belt 9 downward and separates it from the bottom surface of the cigarette box 8, so that the cutting knife 25 can cut the packaging belt 9 without damaging the bottom surface of the cigarette box 8, thereby cutting off the packaging belt 9 on the cigarette box 8 from the bottom, and then the grabbing mechanism 3 grabs and removes the packaging belt 9 from above the cigarette box 8, thereby realizing automatic cutting and removal of the packaging belt 9 on the cigarette box 8.

[0030] Specifically, a lifting cylinder 26 is mounted on the movable bracket 22, and the cutting blade 25 is mounted on the end of the piston rod of the lifting cylinder 26. The lifting cylinder 26 pushes the cutting blade 25 out so that the upper edge of the cutting blade 25 passes through the guide rod 24, so that the packaging strap 9 can be cut when the packaging strap 9 is cut. When not cutting, the cutting blade 25 is retracted below the guide rod 24 to prevent the upper edge of the cutting blade 25 from protruding.

[0031] Specifically, the cutting blade 25 is a circular blade, a diamond-shaped blade, a triangular blade, or a rectangular blade. Specifically, if the cutting blade 25 is a circular blade, it can be rotatably or fixedly connected to the end of the piston rod of the lifting cylinder 26, so that cutting can be performed using rotational motion or linear motion. If the cutting blade 25 is a diamond-shaped blade, a triangular blade, or a rectangular blade, it is fixed to the end of the piston rod of the lifting cylinder 26.

[0032] Specifically, a cutting slot 241 is provided in the middle of the guide rod 24, and the cutting knife 25 is located in the cutting slot 241 during cutting. By providing the cutting slot 241, the cutting knife 25 is located in the cutting slot 241. When cutting, the guide rods 24 on both sides of the cutting knife 25 support the packaging tape 9, thereby facilitating the cutting knife 25 to cut the packaging tape 9.

[0033] Specifically, the movable bracket 22 is equipped with a resilient touch plate 27, located between the barrier rod 23 and the cutting blade 25. A proximity switch sensor 28 is mounted on the barrier rod 23. Movement of the touch plate 27 triggers a change in the proximity switch sensor's electrical signal, enabling the proximity switch sensor 28 to detect the movement of the touch plate 27. If the cutting blade 25 fails to cut the packaging strap 9 on the cigarette box 8, the strap 9 passes over the cutting blade 25 and contacts the touch plate 27, causing the touch plate 27 to move and be detected by the proximity switch sensor 28, allowing the system to resume the cutting operation. The touch plate 27 is resilient, allowing it to automatically reset when the triggering force is removed.

[0034] Specifically, the grabbing mechanism 3 includes a moving block 31 and a grabbing hook 32 hinged on the moving block 31, the grabbing hook 32 includes a support plate 321 and a hook claw 322 fixed at the lower end of the support plate 321, a concave cavity 323 for accommodating the packaging belt 9 is provided between the hook claw 322 and the support plate 321, 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, 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 elastic element 33 pushes the grab hook 32 toward the cigarette box 8, so that the lower end of the hook claw 322 remains 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, thereby grabbing and removing the cut packaging belt 9 from the cigarette box 8.

[0035] Specifically, a limiting plate 34 is hingedly connected to the support plate 321. The lower end of the limiting plate 34 overlaps the hook 322. The angle between the limiting plate 34 and the hook 322 on the side near the cavity 323 is greater than 90 degrees. By providing the limiting plate 34, when the packaging strap 9 is grabbed, the packaging strap 9 abuts the limiting plate 34, causing the limiting plate 34 to swing toward the cavity 323. After the packaging strap 9 passes over the limiting plate 34 and falls into the cavity 323, the limiting plate 34 returns to overlap the hook 322 under the action of gravity, thereby confining the packaging strap 9 in the cavity 323 and preventing the packaging strap 9 from being unhooked from the cavity 323.

[0036] Specifically, a truss manipulator 4 is provided above the support device 1, and the moving block 31 is mounted at the end of the truss manipulator 4. The truss manipulator 4 drives the moving block 31 to move and pick up the packaging tape 9 from the cigarette box 8. The truss manipulator 4 drives the moving block 31 to move horizontally along the upper surface of the cigarette box 8 to pick up the packaging tape 9. The PV packaging tape 9 on the surface of the cigarette box 8 is collected by the gripper, and then the truss manipulator 4 is lifted and the packaging tape 9 is taken 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, with a gap 11 provided between the two rows of roller conveyors to allow for the cutting device 2 to pass through. The double-row roller conveyor facilitates the transport of cigarette boxes 8 to and from the cutting and packaging strips 9 station. Specifically, the double-row roller conveyor is equipped with a securing mechanism to secure the cigarette boxes 8 to the cutting and packaging strips 9 station.

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