DETAILED DESCRIPTION

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Referring to Figure 1-4 , a cutting device for packaging box cardboard, including a base 1 and packaging box cardboard 2. A plurality of conveying rollers 3 are installed at the upper ends on both sides of the fixed frame 16 of the base 1, and the lower surface of the packaging box cardboard 2 is attached to the surface of the conveying rollers 3.

[0024] Cutting mechanism. The cutting mechanism includes a first U-shaped plate 4 fixedly connected to the upper end of the base 1. A groove 5 is opened at the lower end of the first U-shaped plate 4. Two sliding rods 6 are fixedly connected to the inner wall of the groove 5. A second U-shaped plate 7 is slidably connected to the side walls of the two sliding rods 6. A first motor 8 is fixedly connected to the upper end of the second U-shaped plate 7. A rectangular frame 9 is fixedly connected to the movable end of the first motor 8. Two cylinders 10 are fixedly connected to the bottom of the rectangular frame 9. A cutting knife 11 is fixedly connected to the movable ends of the two cylinders 10.

[0025] Furthermore, the rotation of the first motor 8 can drive the rotation of the rectangular frame 9, and then drive the rotation of the cutting knife 11, changing the cutting angle of the cutting knife 11. In this way, the cut end of the packaging box cardboard 2 after one-time cutting can be chamfered and segmented cut, avoiding that the cutting process in the prior art cannot meet this cutting method, and subsequent shifting cutting of the packaging box cardboard or additional cutting treatment on a special device is required, which cannot meet its high-efficiency assembly line operation.

[0026] A blower 19 is fixedly connected to the upper end of the first U-shaped plate 4. An air blowing pipe 20 is fixedly connected to the output end of the blower 19. The nozzle of the air blowing pipe 20 away from the blower 19 is arranged towards the cutting knife 11, which can blow away the scraps cut from the packaging box cardboard 2.

[0027] Two arc-shaped grooves 13 are opened at the lower end of the second U-shaped plate 7. A stabilizing ring 12 is slidably connected to the inner walls of the two arc-shaped grooves 13. The lower end of the stabilizing ring 12 is fixedly connected to the upper end of the rectangular frame 9. When the first motor 8 rotates, it will drive the rotation of the rectangular frame 9 at this time, and then the side wall of the stabilizing ring 12 will slide in the two arc-shaped grooves 13, improving the rotational stability of the rectangular frame 9.

[0028] A lead screw 14 is rotatably connected to the inner wall of the groove 5. The side wall of the lead screw 14 is threadedly connected to the side wall of the second U-shaped plate 7. A second motor 15 is fixedly connected to the side wall of the first U-shaped plate 4. The movable end of the second motor 15 is fixedly connected to one end of the lead screw 14.

[0029] The base 1 is provided with a buffer mechanism, which includes a fixed frame 16 fixedly connected to the upper end of the base 1. The bottom of the fixed frame 16 is elastically connected to a buffer plate 18 through multiple springs 17. The lower surface of the packaging box cardboard 2 is in contact with the upper surface of the buffer plate 18.

[0030] Furthermore, when the cylinder 10 is extended, the cutting knife 11 will be driven to move downward to cut the packaging box cardboard 2. At this time, the cutting knife 11 will drive the buffer plate 18 to move downward, so that the cutting knife 11 can be protected while the packaging box cardboard 2 is cut, avoiding the cutting knife 11 from moving downward and rigidly contacting the cutting surface below the packaging box cardboard 2, which may cause the cutting knife 11 to be easily damaged.

[0031] When the packaging box cardboard 2 is cut, the packaging box cardboard 2 moves on the conveying roller 3 until it passes through the upper surface of the buffer plate 18, and then the two cylinders 10 can be adjusted to extend, and then the cutting knife 11 moves down to complete the cutting of the packaging box cardboard 2;

[0032] Then, the two cylinders 10 are adjusted to contract, so that the cutting knife 11 moves up to the original position, and the subsequent packaging box cardboard 2 can be transported and cut;

[0033] When the cut end of the packaging box cardboard 2 needs to be processed, the first motor 8 can be driven to rotate, and then the rectangular frame 9 drives the cutting knife 11 to rotate, and the cutting angle of the cutting knife 11 is changed, and then the second motor 15 is driven to rotate, so that the screw 14 rotates to drive the second shaped plate 7 to move, and the cutting position of the cutting knife 11 is adjusted again, and then the two cylinders 10 are adjusted to extend again, so that the cut end of the packaging box cardboard 2 after the first cutting can be processed by beveling and segmented cutting;

[0034] After the cutting blade 11 cuts the packaging box cardboard 2, the fan 19 is started, and the air flow blown out by the air blow pipe 20 can blow away the cut pieces of the packaging box cardboard 2 to keep the buffer plate 18 clean.

[0035] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
