[0021] The corrugated cardboard directional cutting device is a mechanical device used to accurately cut corrugated cardboard. This device is particularly important in the packaging industry because it can efficiently and accurately handle the cutting of corrugated cardboard to meet the manufacturing needs of different products. This device can not only meet the market demand for high-quality corrugated cardboard products, but also promote the development of related industries. In the future, with the further advancement of technology and the continuous expansion of market demand, the corrugated cardboard directional cutting device will continue to develop in the direction of greater intelligence, automation and environmental protection to adapt to more diverse and complex market needs;

[0022] See also Figure 1-Figure 5As shown, the present embodiment provides a corrugated cardboard directional cutting device, including a cutting machine workbench 1. The blade of the corrugated cardboard directional cutting device is not convenient to appropriately change the cutting height according to the height of the corrugated cardboard. For some corrugated boards that need to be grooved, creasing and cut, it is not convenient to perform cutting work. In the cutting process, a large amount of paper scraps are easily splashed and affect the surrounding environment. The practicality is low. Therefore, the details are as follows: a sliding bracket 11 is fixedly connected to the top of the cutting machine workbench 1, and a support frame 12 is slidably connected inside the sliding bracket 11. A bottom plate 13 is fixedly connected to the lower end of the support frame 12. A gear 2 is rotatably connected to the inner wall of the cavity of the support frame 12. A first rack 21 is meshed with the outer wall of the gear 2. A directional blade 14 is fixedly connected to the end of the first rack 21. A second rack 22 is meshed with the outer wall on the other side of the gear 2. A pulling block 23 is fixedly connected to the upper end of the second rack 22. The support frame 12 The inner wall is symmetrically provided with a second slide groove 121, and the inner wall of the bottom plate 13 is symmetrically provided with a third slide groove 131. The first rack 21 and the second rack 22 slide on the inner walls of the second slide groove 121 and the third slide groove 131. The corrugated cardboard to be cut is placed on the cutting machine workbench 1. According to the required cutting height, the end of the pulling block 23 is pinched and pulled to drive the second rack 22. The outer wall of the second rack 22 slides in the inner walls of the second slide groove 121 and the third slide groove 131. The outer wall of the second rack 22 drives the end of the gear 2 to rotate on the inner wall of the support frame 12, and the outer wall of the gear 2 drives the first rack 21 at the other end to mesh. At this time, the second rack 22 moves in the opposite direction of the first rack 21, and the second rack 22 drives the directional blade 14 at the end to move downward as well, so as to adjust the contact height between the directional blade 14 and the corrugated board, so as to facilitate users to perform grooving, creasing and cutting on part of the corrugated board, thereby improving practicality.

[0023] A first slide groove 111 is provided on the inner wall of the sliding bracket 11, and the end of the support frame 12 slides on the inner wall of the first slide groove 111. A handle 15 is fixedly connected to the outer wall of the support frame 12, and a support leg 16 is fixedly connected to the lower part of the cutting machine workbench 1. The handle 15 is held and the support frame 12 is pushed horizontally. The end of the support frame 12 slides on the inner wall of the first slide groove 111 on the outer wall of the sliding bracket 11.

The directional blade 14 performs directional cutting on the corrugated board to be cut on the cutting machine workbench 1, so that the corrugated board directional cutting device can perform cutting work normally.

[0024] A protective shell 24 is fixedly connected below the bottom plate 13, and an inner shell 25 is slidably connected to the inner wall of the protective shell 24. The outer wall size of the inner shell 25 is slidably adapted to the inner wall cavity size of the protective shell 24. An electric telescopic rod 26 is fixedly connected below the bottom plate 13, and a fixed block 27 is fixedly connected to the end of the electric telescopic rod 26. The outer wall of the fixed block 27 is fixedly connected to the end of the inner shell 25. The fixed block 27 at the end of the electric telescopic rod 26 drives the inner shell 25 to slide on the inner wall of the protective shell 24. The height of the inner shell 25 is adjusted according to the height of the directional blade 14 and the corrugated board. After adjustment, the electric telescopic rod 26 is closed, and the handle is held. The hand 15 pushes the support frame 12 horizontally, and the end of the support frame 12 slides on the inner wall of the first slide groove 111 on the outer wall of the sliding bracket 11. The support frame 12 drives the directional blade 14 below to move horizontally. The directional blade 14 performs directional cutting on the corrugated board to be cut on the cutting machine workbench 1. The inner shell 25 and the protective shell 24 block the paper scraps generated during the cutting process inside the protective shell 24 and the inner shell 25 to prevent the paper scraps from splashing out. At the same time, the directional blade 14 is protected to prevent the user from being injured by the directional blade 14 due to accidental touch during operation, thereby improving safety.

[0025] Among them, the electric telescopic rod 26 is a device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The core components of the electric telescopic rod include an electric motor, a reduction gear worm gear, a screw, a nut, etc. The electric motor is a power source, which generates mechanical energy through electrical energy to drive the operation of the entire system. This is common knowledge among people in the technical field and will not be elaborated here.

[0026] The improvement of this embodiment is that:

[0027] Pinch the pulling block 23 to slide the second rack 22 up and down, driving the gear 2 to rotate and mesh with the first rack 21. The directional blade 14 at the end of the first rack 21 will change the cutting height following the displacement of the first rack 21, which is convenient for users to cut corrugated boards that need to be grooved, indented and cut. At the same time, the electric telescopic rod 26 under the bottom plate 13 drives the inner shell 25 to slide on the protective shell 24 energy wall, and the height of the inner shell 25 protection can be changed according to the height of the directional blade 14 to prevent paper scraps from flying around, thereby improving practicality. A sliding bracket 11 is fixedly connected above the cutting machine workbench 1, and a support frame 12 is slidably connected inside the sliding bracket 11. The lower end of the support frame 12 is fixedly connected to the bottom plate 13, and the inner wall of the cavity of the support frame 12 is rotatably connected to the gear 2. 2 is meshed with a first rack 21, and the end of the first rack 21 is fixedly connected with a directional blade 14. The outer wall of the other side of the gear 2 is meshed with a second rack 22, and the upper end of the second rack 22 is fixedly connected with a pulling block 23. The end of the pulling block 23 is pinched to pull the second rack 22, and the outer wall of the second rack 22 drives the end of the gear 2 to rotate on the inner wall of the support frame 12. The outer wall of the gear 2 drives the first rack 21 at the other end to mesh and move. At this time, the second rack 22 moves in the opposite direction to the first rack 21, and the second rack 22 drives the directional blade 14 at the end to move downward. When the end of the directional blade 14 contacts the corrugated board to be cut, stop pulling the pulling block 23, adjust the fixation of the directional blade 14, and cut the corrugated board at different heights to improve practicality.

[0028] Taking into account that the above-mentioned method of adjusting the height of the directional blade 14 is still insufficient, the inner wall of the support frame 12 is symmetrically provided with a second slide groove 121, and the inner wall of the base plate 13 is symmetrically provided with a third slide groove 131. The first rack 21 and the second rack 22 slide on the inner walls of the second slide groove 121 and the third slide groove 131. The second rack 22 is pulled upward, and the outer wall of the second rack 22 slides on the inner walls of the second slide groove 121 and the third slide groove 131. At this time, the outer wall of the first rack 21 slides in the opposite direction on the inner walls of the other second slide groove 121 and the third slide groove 131, driving the directional blade 14 to slide smoothly, making it convenient for the user to adjust the height of the directional blade 14.

[0029] In order to enable the corrugated cardboard directional cutting device to perform cutting work normally, a first slide groove 111 is provided on the inner wall of the sliding bracket 11, and the end of the support frame 12 slides on the inner wall of the first slide groove 111. A handle 15 is fixedly connected to the outer wall of the support frame 12, and a support leg 16 is fixedly connected under the cutting machine workbench 1. The support leg 16 supports the main body of the cutting machine workbench 1. Hold the handle 15 and push the support frame 12 horizontally. The end of the support frame 12 slides on the inner wall of the first slide groove 111 on the outer wall of the sliding bracket 11. The support frame 12 drives the directional blade 14 below to move horizontally. The directional blade 14 performs directional cutting work on the corrugated board to be cut on the cutting machine workbench 1, so that the corrugated cardboard directional cutting device can perform cutting work normally.

[0030] Taking into account that paper scraps generated during the cutting process will fly everywhere, it is necessary to adjust the protection height according to the height of the directional blade 14. A protective shell 24 is fixedly connected to the bottom of the base plate 13, and an inner shell 25 is slidably connected to the inner wall of the protective shell 24. The outer wall size of the inner shell 25 is slidably adapted to the size of the inner wall cavity of the protective shell 24. The inner shell 25 slides on the inner wall of the protective shell 24. According to the height of the directional blade 14 and the corrugated board, the height of the inner shell 25 is adjusted to block the splashing of paper scraps and prevent the splashing of paper scraps from affecting the surrounding environment. At the same time, the directional blade 14 is protected to prevent the user from being injured by the directional blade 14 during operation, thereby improving safety.

[0031] Taking into account that manually adjusting the height of the inner shell 25 is time-consuming and laborious, an electric telescopic rod 26 is fixedly connected under the bottom plate 13, and a fixed block 27 is fixedly connected to the end of the electric telescopic rod 26. The outer wall of the fixed block 27 is fixedly connected to the end of the inner shell 25. The fixed block 27 at the end of the electric telescopic rod 26 drives the inner shell 25 to slide on the inner wall of the protective shell 24, so that the user can adjust the height of the inner shell 25 according to the height of the directional blade 14 and the corrugated board to block the paper scraps generated during cutting.

[0032] In summary, the working principle of this scheme is as follows:

[0033] When the utility model corrugated cardboard directional cutting device is used, the corrugated cardboard to be cut is placed on the cutting machine workbench 1, and the supporting legs 16 under the cutting machine workbench 1 support the main body of the cutting machine workbench 1. According to the required cutting height, the end of the pulling block 23 is pinched, and the second rack 22 is pulled upward. The outer wall of the second rack 22 slides on the inner wall of the second slide groove 121 and the third slide groove 131. The outer wall of the second rack 22 drives the end of the gear 2 to rotate on the inner wall of the support frame 12, and the outer wall of the gear 2 drives the first rack 21 at the other end to mesh. At this time, the second rack 22 moves in the opposite direction to the first rack 21, and the second rack 22 drives the directional blade 14 at the end to move downward as well. When the end of the directional blade 14 contacts the corrugated board to be cut, it stops. Pull the pulling block 23 to open the electric telescopic rod 26 under the bottom plate 13, and the fixed block 27 at the end of the electric telescopic rod 26 drives the inner shell 25 to slide on the inner wall of the protective shell 24. According to the height of the directional blade 14 and the corrugated board, the height of the inner shell 25 is adjusted. After adjustment, the electric telescopic rod 26 is closed, and the handle 15 is held to push the support frame 12 horizontally. The end of the support frame 12 slides on the inner wall of the first slide groove 111 on the outer wall of the sliding bracket 11. The support frame 12 drives the directional blade 14 below to move horizontally. The directional blade 14 performs directional cutting on the corrugated board to be cut on the cutting machine workbench 1. The inner shell 25 and the protective shell 24 block all the paper scraps generated during the cutting process inside the protective shell 24 and the inner shell 25 to prevent the paper scraps from splashing out and affecting the surrounding environment.
