[0025] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0026] Example 1

[0027] See Figures 1 to 8This utility model provides a protective device for preventing cuts on a sawing machine, comprising a protective cover 1, a stationary operating table 2, a movable operating table 3, an elastic element 4, and a support frame 5. The stationary operating table 2 is installed on the table surface 9 of the sawing machine 8, providing support for the plate to be cut. The sawing machine 8 is a vertical sawing machine. The movable operating table 3 is slidably connected to the table surface 9 of the sawing machine 8. The plate is placed on the movable operating table 3, and the movable operating table 3 slides to bring the plate closer to the saw blade 10, which cuts the plate. The stationary operating table 2 and the movable operating table 3 are located on the left and right sides of the saw blade 10, respectively, with a gap between them. The saw blade 10 is located within this gap. One end of the elastic element 4 is connected to the movable operating table 3, and the other end is connected to the sawing machine 8. The support frame 5 is installed on the movable operating table 9. On platform 3, elastic element 4 is a pressure spring. The support frame 5 is connected to the protective cover 1. The protective cover 1 is located above the gap, and when elastic element 4 is at its free length, the protective cover 1 covers the outer periphery of the saw blade 10. The protective cover 1 is used to protect the saw blade 10. During the cutting operation, the moving operating platform 3 moves the board closer to the saw blade 10. As the moving operating platform 3 moves, the protective cover 1 separates from the saw blade 10, and the saw blade 10 can contact the board to cut it. After the cutting operation is completed, the force on the moving operating platform 3 is removed, elastic element 4 returns to its original position, and the protective cover 1 automatically covers the saw blade 10 as the moving operating platform 3 returns to its original position, preventing accidental cuts. This effectively avoids accidental injury to the operator when the saw blade 10 is in working condition but not cutting the board, reducing safety hazards and playing a protective role.

[0028] The support frame 5 includes a support base 6 and a support rod 7. The support base 6 is installed on the movable operating table 3. The two ends of the support rod 7 are respectively connected to the support base 6 and the protective cover 1, which supports the protective cover 1 and allows the protective cover 1 to move with the movable operating table 3, so that it can be separated when cutting the plate and cover the saw blade 10 when not cutting.

[0029] The stationary operating table 2 is provided with a material discharge port 17. The cut-off material is collected in the material box of the saw 8 through the material discharge port 17. The side of the material discharge port 17 near the saw blade 10 is a guide surface.

[0030] The movable operating table 3 includes a table plate 11 and a plurality of sliding connectors 12 respectively connected to the bottom sides of the table plate 11. The plurality of sliding connectors 12 are connected to the bottom sides of the table plate 11 to improve the stability of the sliding of the table plate 11. The plurality of sliding connectors 12 are slidably connected to the slide rails 15 set on the table surface 9 of the sawing machine 8. The table plate 11 is slidably connected to drive the plate to move back and forth. The sliding connectors 12 include a connecting plate 13 and a plurality of sliders 14 connected to the left and right sides of the connecting plate 13. The connecting plate 13 is connected to the bottom of the table plate 11. The slide rails 15 are provided with grooves 16 on both sides, and the plurality of sliders 14 are slidably connected in the grooves 16.

[0031] The static operating table 2 is connected to a first positioning component, and the rear side of the dynamic operating table 3 is connected to a second positioning baffle a, which limits the cutting of the plate material and facilitates the saw blade 10 to cut the plate material stably.

[0032] The first positioning component includes a first positioning baffle a and a first positioning baffle b. The first positioning baffle a and the first positioning baffle b are connected to the side of the stationary operating table 2. The first positioning baffle a is connected to the rear side of the stationary operating table 2, and the first positioning baffle b is connected to the left side of the stationary operating table 2. The first positioning baffle a and the first positioning baffle b are connected to form an L-shape.

[0033] When in use, start the saw 8, and the saw blade 10 moves up and down reciprocally. Place the board to be cut on the moving operating table 3, with the front end of the board against the second positioning baffle a. Push the board forward. Due to the friction between the front end of the board against the second positioning baffle a and the board and the moving operating table 3, the moving operating table 3 moves forward as the board is pushed forward, and the board continuously approaches the saw blade 10. The protective cover 1 is fixed to the moving operating table 3 by the support frame 5. As the moving operating table 3 moves forward, the protective cover 1 separates from the saw blade 10. The saw blade 10 cuts the board. After cutting, the pushing force is removed, the elastic element 4 resets, and the moving operating table 3 drives the protective cover 1 back to its original position. The protective cover 1 automatically covers the saw blade 10, effectively avoiding accidental injury to the operator when the saw blade 10 is in working condition and not cutting the board.

[0034] Example 2

[0035] See Figure 9The difference between this embodiment and embodiment 2 is that: the movable operating table 3 is further provided with a second positioning component. The second positioning component includes a second positioning baffle and a telescopic member. The fixed end of the telescopic member is installed on the movable operating table 3, and the movable end of the telescopic member is connected to the second positioning baffle. The second positioning baffle is located above the movable operating table 3. According to the width of the material to be cut and the cutting position, the movable end of the telescopic member extends, and the second positioning baffle pushes the plate to move towards the side closer to the saw blade 10. The telescopic member can be an electric telescopic rod or a hydraulic telescopic rod.
