[0005] This utility model provides the following technical solution: a cutting device for packaging box production, including a processing table, a support frame fixedly installed on the top of the processing table, and positioning mechanisms for clamping and limiting the packaging box are fixedly installed on the inner walls of the front and rear sides of the support frame. A cutting mechanism for cutting the packaging box is also fixedly installed on the other side of the support frame, and a recycling mechanism for recycling the waste generated during the cutting of the packaging box is also fixedly installed on the surface of the cutting mechanism.

[0006] The positioning mechanism includes a first movable groove, a bidirectional lead screw, a first slider, a connecting rod, a movable frame, a spring-loaded telescopic rod, and a buffer air cushion. The first movable groove is formed on the inner wall of the support frame, and a bidirectional lead screw is rotatably connected between the inner walls on both sides of the first movable groove. The two ends of the bidirectional lead screw are threadedly connected to the first sliders. The movable frame is located on the rear side of the first movable groove, and a connecting rod is movably hinged between the movable frame and two adjacent first sliders. Several spring-loaded telescopic rods are fixedly installed on the side of the movable frame away from the connecting rods, and a buffer air cushion is fixedly installed on the end of each spring-loaded telescopic rod away from the movable frame. Two first motors are fixedly installed on one side of the support frame, and the output ends of the two first motors are respectively fixedly connected to one end of the corresponding bidirectional lead screw.

[0007] As a preferred embodiment of the above technical solution, the cutting mechanism includes a fixed frame, a cylinder, a drive rod, and a cutting tool. The fixed frame is fixedly installed on the other side of the top of the support frame, and a cylinder is fixedly installed on the top of the fixed frame. A drive rod is fixedly connected to the bottom output end of the cylinder. The drive rod passes through the surface of the fixed frame, and a cutting tool is fixedly installed at the end of the drive rod away from the cylinder.

[0008] As a preferred embodiment of the above technical solution, the recycling mechanism includes a dust collection box, a telescopic hose, and a dust collection plate. The dust collection box is fixedly installed on the top of the support frame. There are two dust collection plates, both of which are fixedly installed on the top of the cutting blade. Dust collection ports are provided on both sides of the two dust collection plates. The output end of the dust collection box is fixedly connected to the corresponding dust collection plate through two telescopic hoses.

[0009] As a preferred embodiment of the above technical solution, a placement platform is also fixedly installed on the top of the processing table.

[0010] As a preferred embodiment of the above technical solution, an L-shaped pusher plate is fixedly installed on the top of the second slider, and a cutting groove for protecting the surface of the placement table is also provided on the surface of the placement table, the cutting groove being located at the bottom of the cutting tool.

[0011] As a preferred embodiment of the above technical solution, a conveyor belt is also fixedly installed on the top of the processing table, and the conveyor belt is located on the other side of the placement table.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a positioning mechanism that uses a first motor to drive a bidirectional lead screw to rotate, which in turn drives a first slider linkage and a moving frame. This, combined with a spring-loaded telescopic rod and a cushioning air pad, achieves flexible clamping of the packaging box. This mechanism avoids the surface indentations and damage caused by traditional rigid clamping, and can adapt to the clamping needs of packaging boxes of different sizes, improving clamping stability and versatility.

[0014] Based on the aforementioned beneficial effects, this utility model incorporates a cutting mechanism and a recycling mechanism. The cutting mechanism uses a cylinder to drive the cutting blade for precise lifting and lowering, meeting the cutting needs of packaging boxes of varying thicknesses. The recycling mechanism, utilizing a dust collection box, telescopic hose, and dust collection plate, simultaneously absorbs waste debris during the cutting process. The coordinated operation of these two mechanisms ensures cutting accuracy while preventing waste debris from scattering and polluting the environment, thus avoiding health risks for operators. Compared to existing cutting devices that lack simultaneous waste debris handling capabilities, this significantly improves the processing environment and reduces subsequent cleaning costs.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-6 As shown, this utility model provides a technical solution: a cutting device for packaging box production, including a processing table 1, a support frame 2 fixedly installed on the top of the processing table 1, and positioning mechanisms 3 for clamping and limiting the packaging box are fixedly installed on the inner walls of the front and rear sides of the support frame 2. A cutting mechanism 4 for cutting the packaging box is also fixedly installed on the other side of the support frame 2. A recycling mechanism 5 for recycling the waste generated during the cutting of the packaging box is also fixedly installed on the surface of the cutting mechanism 4.

[0024] The positioning mechanism 3 includes a first movable groove 6, a bidirectional lead screw 7, a first slider 8, a connecting rod 9, a movable frame 10, a spring-type telescopic rod 11, and a buffer air cushion 12. The first movable groove 6 is opened on the inner wall of the support frame 2, and the bidirectional lead screw 7 is rotatably connected between the inner walls on both sides of the first movable groove 6. The two ends of the bidirectional lead screw 7 are threadedly connected to the first slider 8. The movable frame 10 is located on the rear side of the first movable groove 6, and the movable frame 10 is movably hinged to the two adjacent first sliders 8 by the connecting rod 9. Several spring-type telescopic rods 11 are fixedly installed on the side of the movable frame 10 away from the connecting rod 9, and a buffer air cushion 12 is fixedly installed on the end of each spring-type telescopic rod 11 away from the movable frame 10. Two first motors 13 are fixedly installed on one side of the support frame 2, and the output ends of the two first motors 13 are respectively fixedly connected to one end of the corresponding bidirectional lead screw 7.

[0025] The first motor 13 drives the bidirectional lead screw 7 to rotate. The rotation of the bidirectional lead screw 7 causes the first sliders 8 at both ends to move away from or towards each other. When the first sliders 8 move, they drive the moving frame 10 to move as a whole through the connecting rod 9, so that the two moving frames 10 move closer or further apart. When the moving frame 10 approaches the packaging box, the surface buffer air cushion 12 first contacts the surface of the packaging box and works with the spring-type telescopic rod 11 to provide buffer protection when clamping the packaging box.

[0026] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the cutting mechanism 4 includes a fixed frame 14, a cylinder 15, a drive rod 16, and a cutting tool 17. The fixed frame 14 is fixedly installed on the other side of the top of the support frame 2, and the cylinder 15 is fixedly installed on the top of the fixed frame 14. The drive rod 16 is fixedly connected to the bottom output end of the cylinder 15. The drive rod 16 passes through the surface of the fixed frame 14, and the cutting tool 17 is fixedly installed at the end of the drive rod 16 away from the cylinder 15.

[0027] Driven by the cylinder 15, the drive rod 16 moves steadily downward along the through hole of the mounting bracket 14. As the drive rod 16 moves downward, the cutting tool 17 fixedly mounted at its bottom also moves downward synchronously. When the cutting tool 17 contacts the part of the packaging box to be cut, the continuously moving tool will cut the packaging box with its sharp edge. During the cutting process, the downward depth of the cutting tool 17 can be adjusted by controlling the output stroke of the cylinder 15, thereby meeting the cutting requirements of packaging boxes of different thicknesses, ensuring accurate cutting depth, and avoiding incomplete cutting or over-cutting that could damage the processing table 1. After cutting is completed, the output end of the control cylinder 15 retracts, driving the drive rod 16 and the cutting tool 17 to return to their original position, preparing for the next cutting operation.

[0028] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the recycling mechanism 5 includes a dust collection box 18, a telescopic hose 19, and a dust collection plate 20. The dust collection box 18 is fixedly installed on the top of the support frame 2. There are two dust collection plates 20, both of which are fixedly installed on the top of the cutting blade 17. Dust collection ports are opened on both sides of the two dust collection plates 20. The output end of the dust collection box 18 is fixedly connected to the corresponding dust collection plate 20 through two telescopic hoses 19.

[0029] While the cutting mechanism 4 is performing the cutting operation, the negative pressure suction device inside the dust collection box 18 is activated. After generating negative pressure, the dust collection box 18 creates suction through the two telescopic hoses 19 connected to its output end. Since the two suction plates 20 are fixedly installed on top of the cutting blade 17 and located on both sides of the cutting area, the suction ports on both sides of the suction plates 20 are directly aimed at the area where waste is generated during the cutting process. Under the action of negative pressure, waste such as paper scraps and wood chips generated during cutting are sucked into the suction ports and then transported to the inside of the dust collection box 18 through the telescopic hoses 19. The telescopic hoses 19 are extendable and can freely extend and retract with the up-and-down movement of the cutting blade 17, always maintaining a stable connection between the suction plates 20 and the dust collection box 18, without affecting the normal movement of the cutting blade 17.

[0030] As one implementation method in this embodiment, please refer to Figures 1-2 and Figure 6 As shown, a placement platform 21 is also fixedly installed on the top of the processing table 1. A second movable groove 22 is opened inside the placement platform 21. A screw 23 is rotatably connected between the inner walls on both sides of the second movable groove 22. A second slider 24 is threadedly connected to the outside of the screw 23. A second motor 25 is fixedly installed on one side of the placement platform 21. The output end of the second motor 25 is fixedly connected to one end of the screw 23.

[0031] After placing the packaging box to be cut on the surface of the placement platform 21, the second motor 25, fixedly installed on one side of the placement platform 21, is started according to the size of the packaging box and the cutting position requirements. The output end of the second motor 25 rotates, which drives the screw 23 fixedly connected to it to rotate inside the second movable groove 22. The rotation of the screw 23 is converted into the linear movement of the second slider 24 along the length of the second movable groove 22. By controlling the forward and reverse rotation of the second motor 25, the second slider 24 can be reciprocated within the second movable groove 22, thereby driving the L-shaped pusher plate 26 fixedly installed on the top of the second slider 24 to move. During the movement, the side of the pusher plate 26 perpendicular to the surface of the placement platform 21 will contact the side of the packaging box, pushing the packaging box to move on the surface of the placement platform 21 until the packaging box is adjusted to the preset cutting position, ensuring that the cutting blade 17 can accurately act on the part to be cut.

[0032] As one implementation method in this embodiment, please refer to Figures 2-3 and Figure 6 As shown, an L-shaped pusher plate 26 is fixedly installed on the top of the second slider 24, and a cutting groove 27 for protecting the surface of the placement table 21 is also provided on the surface of the placement table 21. The cutting groove 27 is located at the bottom of the cutting tool 17.

[0033] The pusher plate 26 has an L-shaped structure. Its horizontal part is fixedly connected to the top of the second slider 24, and its vertical part is used to push the packaging box. During the pushing process, the L-shaped structure can ensure stable contact between the pusher plate 26 and the packaging box, preventing the packaging box from shifting or tipping over. The slit groove 27 on the surface of the placement table 21 is located at the bottom of the cutting tool 17, and its size is slightly larger than the size of the cutting tool 17. When the cutting tool 17 cuts downwards into the packaging box, it will cut directly into the slit groove 27, rather than contacting the surface of the placement table 21.

[0034] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a conveyor belt 28 is also fixedly installed on the top of the processing table 1, and the conveyor belt 28 is located on the other side of the placement table 21.

[0035] After the packaging box is cut, the second motor 25 is started again to control the second slider 24 to drive the pusher plate 26 to continue moving, pushing the cut packaging box from the surface of the placement table 21 to the conveyor belt 28.

[0036] Working Principle: The operator places the packaging box to be cut on the placement platform 21 of the processing table 1, starts the first motor 13 on the side of the support frame 2, drives the bidirectional lead screw 7 to rotate, causing the first slider 8 to move closer, and pushes the moving frame 10 through the connecting rod 9. The spring-loaded telescopic rod 11 on the moving frame 10 cooperates with the buffer air cushion 12 to clamp the packaging box. Then, the second motor 25 on the side of the placement platform 21 is started, drives the screw 23 to rotate, and moves the second slider 24 and the top L-shaped pusher plate 26, adjusting the packaging box to be directly below the cutting tool 17. Next, the cylinder 15 on the fixed frame 14 is started, pushing the drive rod 16 to move the cutting tool 17 down to cut, while the dust collection box 18 collects waste through the telescopic hose 19 and the dust collection plate 20 suction port. After cutting, the cylinder 15 drives the tool to reset, and the pusher plate 26 pushes the packaging box to the conveyor belt 28. The conveyor belt 28 transports the packaging box to the subsequent stage, completing one processing cycle. All parts work together to achieve automated cutting.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
