[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a protective device for cutting wood-plastic composite flooring, including a placement platform 1, a U-shaped protective shell 2 on the top of the placement platform 1, a dustproof box 3 fixedly connected to the top of the U-shaped protective shell 2, a lifting structure between the dustproof box 3 and the placement platform 1, the lifting structure including a T-shaped plate 12 and a hydraulic cylinder 13, the T-shaped plate 12 being fixedly connected to the top of the dustproof box 3, the bottom end of the T-shaped plate 12 penetrating through the placement platform 1 and slidingly connected to the placement platform 1, the hydraulic cylinder 13 being fixedly connected to the outside of the placement platform 1, and the top end of the hydraulic cylinder 13 being fixedly connected to the T-shaped plate 12;

[0024] The dust box 3 has two rotating shafts 4 inside. The bottom ends of both rotating shafts 4 are rotatably connected to the U-shaped protective shell 2, and the top ends of both rotating shafts 4 are rotatably connected to the top of the inside of the dust box 3. A worm gear 5 is fixedly connected to the outer side of the bottom end of the rotating shaft 4. A worm 6 is meshed with the outer side of the worm gear 5. Both ends of the worm 6 pass through the inside of the dust box 3 and are rotatably connected to the dust box 3. A handle is installed at one end of the worm 6. A gear 7 is fixedly connected to the outer side of the top end of the rotating shaft 4. A rack 8 is meshed with the outer side of the gear 7. The top of the inside of the dust box 3 is open. Two T-shaped grooves 300 are provided. A T-shaped block 9 is fixedly connected to the top of the rack 8. The T-shaped block 9 is set inside the T-shaped groove 300 and is slidably connected to the dustproof box 3. A U-shaped rod 10 is fixedly connected to one end of the rack 8. The U-shaped rod 10 passes through the inside of the dustproof box 3 and is slidably connected to the dustproof box 3. A transparent protective plate 11 is fixedly connected to one end of the U-shaped rod 10. The transparent protective plate 11 is slidably set inside the U-shaped protective shell 2. A cutting structure is provided at the center of the top of the placement platform 1. A limiting structure is provided at the top of the placement platform 1.

[0025] Specifically, hydraulic cylinder 13 is activated, which can adjust the up and down position of T-shaped plate 12. Since the bottom end of T-shaped plate 12 passes through and slides through the platform 1, and the top end of hydraulic cylinder 13 is fixedly connected to T-shaped plate 12, hydraulic cylinder 13 drives T-shaped plate 12 to move up and down, thereby driving the U-shaped protective shell 2 at the bottom of dustproof box 3 to adjust its position so that U-shaped protective shell 2 can contact wood-plastic flooring of different thicknesses, thereby achieving effective protection for wood-plastic flooring of different specifications.

[0026] When the throttle is turned, the worm gear 6 meshes with the worm wheel 5 fixed on the outer side of the bottom end of the shaft 4. The shaft 4 rotates on the dust box 3 and the U-shaped protective shell 2. The gear 7 fixedly connected to the outer side of the top end of the shaft 4 rotates accordingly. The gear 7 meshes with the rack 8. The T-shaped block 9 fixedly connected to the top of the rack 8 slides in the T-shaped groove 300 opened at the top of the dust box 3, thereby ensuring the stability of the rack 8's movement. The rack 8 drives the transparent protective plate 11 to slide inside the U-shaped protective shell 2 through the U-shaped rod 10. By adjusting the two transparent protective plates 11 inside the U-shaped protective shell 2, the opening size of the U-shaped protective shell 2 can be changed, so that the device can effectively protect narrower plastic flooring and prevent debris from splashing out from the gaps.

[0027] Example: Figure 1 , Figure 3 and Figure 4 As shown, the cutting structure includes a cutting hole 19, a mounting groove 21, and a slag guide hopper 100. The cutting hole 19 is located at the top of the placement platform 1, and the mounting groove 21 is located at the bottom of the placement platform 1. A cutting blade 20 is provided inside the cutting hole 19. A motor 22 is fixedly installed inside the mounting groove 21. The output end of the motor 22 passes through the inner side of the mounting groove 21 and extends into the cutting hole 19. The output end of the motor 22 is rotatably connected to the placement platform 1 and fixedly connected to the cutting blade 20. The slag guide hopper 100 is fixedly connected to the bottom of the placement platform 1 and is located at the position of the cutting hole 19.

[0028] Specifically, the motor 22 is started. The specific model of the motor 22 is not limited, but depends on the compatible equipment. The output end of the motor 22 drives the cutting blade 20 to rotate in the cutting hole 19, thereby realizing the cutting of the wood-plastic flooring. In this structure, the motor 22 is set in the mounting groove 21, which can increase the heat dissipation of the motor 22 and avoid the motor 22 from overheating and being damaged due to long-term operation. At the same time, the slag guide hopper 100 is fixedly connected to the bottom of the placement platform 1 and is set at the position of the cutting hole 19. Its function is to prevent debris from splashing from the bottom of the placement platform 1. The slag guide hopper 100 can effectively collect the debris and keep the working environment clean.

[0029] Example: Figure 1 , Figure 3 and Figure 4As shown, the limiting structure includes two push plates 14, both of which are located on the bottom sides of the placement platform 1. A hydraulic cylinder 15 is fixedly connected to one side of each of the two push plates 14, and both hydraulic cylinders 15 are fixedly connected to the placement platform 1. Two L-shaped plates 16 are provided on one side of each push plate 14, and both L-shaped plates 16 are fixedly connected to the placement platform 1. One end of each L-shaped plate 16 passes through the push plate 14 and is slidably connected to the cutting hole 19. The limiting structure also includes four sliding grooves 17, all of which are located on the top of the placement platform 1. A positioning block 18 is slidably arranged inside each of the four sliding grooves 17. The four positioning blocks 18 are arranged in pairs, and the two sets of positioning blocks 18 are fixedly connected to the top of the two push plates 14 respectively.

[0030] Specifically, hydraulic cylinder 2 15 is activated, which pushes push plate 14 to slide on two L-shaped plates 16. Push plate 14 drives two positioning blocks 18 to move, thereby enabling multiple positioning blocks 18 to limit the cutting of the wood-plastic flooring, ensuring the stability of the wood-plastic flooring during the cutting process, reducing cutting errors caused by the movement of the board. At the same time, this design reduces the number of hydraulic cylinders 2 15 used, thus reducing the cost of the equipment.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
