[0002] As the name suggests, a packaging box is a box used to package products. With the rapid development of modern industry and the continuous improvement of people's living standards, the demand for packaging boxes will continue to increase. Most of the packaging boxes used on the market are paper packaging boxes. Before production, packaging boxes need to be cut by cutting equipment and then further processed into equal-sized shapes.

[0003] However, existing cutting equipment lacks positioning and fixing mechanisms when cutting multiple stacked cardboard boxes, causing the cardboard to move during cutting, resulting in uneven cut surfaces and affecting the quality of the finished product. Furthermore, prolonged cutting of cardboard over a long period can cause the blades to become dull, reducing their sharpness and leading to incomplete cutting of the cardboard. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for packaging box production, which can press and fix stacked cardboard to prevent the cardboard from moving during cutting, and simultaneously sharpen the cutting blade to ensure the sharpness of the cutting blade, thereby avoiding the phenomenon of insufficient cutting of cardboard.

[0005] To achieve the above objectives, a cutting device for packaging box production is provided, including a workbench. A support frame is fixedly installed on the workbench. A lifting and moving cutting component is provided on the top of the support frame. A pressing and fixing component for pressing and limiting the cardboard is provided below the cutting component.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model provides a cutting device for packaging box production, which includes a workbench 1, a support frame 2 fixedly installed on the workbench 1, a lifting and moving cutting component 3 on the top of the support frame 2, a pressing and fixing component 4 for pressing and limiting the cardboard below the cutting component 3, a limiting groove 201 on both the left and right sides of the support frame 2, the limiting groove 201 slidingly engaging with the cutting component 3 and the pressing and fixing component 4, a centering limiting device 6 for limiting the two sides of the cardboard on the rear side of the support frame 2, and a cutting groove 101 that cooperates with the cutting component 3 on the workbench 1.

[0024] The cutting assembly 3 includes a hydraulic rod 301, which is fixedly installed on the top of the support frame 2. A lifting plate 302 is fixedly connected to the lower movable end of the hydraulic rod 301. The left and right sides of the lifting plate 302 are slidably connected to the inner walls of the two side limiting grooves 201 respectively. A cutting blade 303 is fixedly installed at the bottom of the lifting plate 302.

[0025] The pressing and fixing assembly 4 includes a pressure plate 401. The left and right sides of the pressure plate 401 are slidably connected to the inner walls of the two side limiting grooves 201 respectively. The top left and right sides of the pressure plate 401 are fixedly connected to springs 402. The top of springs 402 is fixedly connected to the bottom of the lifting plate 302. The pressure plate 401 has a slot 4011 in the middle. The slot 4011 is equipped with a grinding tool assembly 5. The cutting groove 101 corresponds to the position of the cutting blade 303 and the slot 4011.

[0026] The sharpening assembly 5 includes sharpening plates 501 arranged symmetrically front and rear. Each sharpening plate 501 has a chamfered corner 5011 on its opposite surface. A sliding rod 502 is fixedly connected to each opposite side of the two sharpening plates 501. The other end of each sliding rod 502 passes through the side wall of the pressure plate 401 and is fixedly connected to a stop block 503. A spring 504 is wound around the sliding rod 502 at the slot 4011. Through the support frame 2, cutting assembly 3, pressing and fixing assembly 4, and sharpening assembly 5, in use, the stacked cardboard is placed under the pressing and fixing assembly 4. Next, the hydraulic rod 301 is activated to push the lifting plate 302 and the pressure plate 401 to slide stably downwards along the limiting groove 201 until... When the pressure plate 401 contacts the cardboard, it continues to press down. Spring 402 uses its elasticity to push the pressure plate 401 to press and fix the stacked cardboard, preventing the cardboard from moving during cutting. At the same time, the descending cutting blade 303 uses its curved blade and cutting groove 101 to cut the cardboard. While cutting, the guide angle 5011 guides the cutting blade 303 through the space between the two grinding plates 501. Springs 504 on both sides push the grinding plates 501, so that their surfaces are in contact with the surface of the cutting blade 303. This allows the cutting blade 303 to be sharpened while cutting, ensuring the sharpness of the cutting blade 303 and thus avoiding insufficient cutting of the cardboard.

[0027] The centering limiting device 6 includes a fixed frame 601, which is fixedly installed on the upper surface of the workbench 1. The left and right side walls of the fixed frame 601 are rotatably connected to a bidirectional threaded rod 602. One end of the bidirectional threaded rod 602 is fixedly connected to a knob 603. The side wall of the bidirectional threaded rod 602 is threadedly connected to a displacement block 604 symmetrically arranged on the left and right. The top of each displacement block 604 is in contact with the lower top surface of the fixed frame 601, and the bottom of each displacement block 604 is rotatably connected to a rotating column 605. Through the centering limiting device 6, the stacked cardboard is pushed to the cutting position. The knob 603 drives the bidirectional threaded rod 602 to rotate, which, in conjunction with the limiting of the fixed frame 601, drives the displacement blocks 604 and rotating columns 605 on both sides to move towards each other until the rotating columns 605 on both sides limit the two sides of the cardboard. This ensures that the stacked cardboard is aligned and centered when pushed, ensuring a flat cutting surface and improving the yield rate.

[0028] Working principle: In use, the stacked cardboard is pushed to the cutting point. The knob 603 drives the bidirectional threaded rod 602 to rotate, which, in conjunction with the limiting action of the fixing frame 601, causes the displacement blocks 604 and rotating columns 605 on both sides to move towards each other until the rotating columns 605 limit the cardboard on both sides. Then, the stacked cardboard is pushed forward. When the stacked cardboard is pushed below the pressing and fixing assembly 4, the hydraulic rod 301 is activated to push the lifting plate 302 and the pressure plate 401 to slide steadily downwards along the limiting groove 201 until the pressure plate 401 contacts the cardboard. The pressure plate continues to press downwards, and the spring 402... The elastic push plate 401 presses and fixes the stacked cardboard to prevent it from moving during cutting. At the same time, the descending cutting blade 303 uses its curved blade and cutting groove 101 to cut the cardboard. During the cutting, the guide angle 5011 guides the cutting blade 303 through the space between the two grinding plates 501. The springs 504 on both sides push the grinding plates 501 to make their surfaces fit against the surface of the cutting blade 303. This allows the cutting blade 303 to be sharpened while cutting, ensuring the sharpness of the cutting blade 303 and avoiding insufficient cutting of the cardboard.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
