[0002] Chinese patent document CN216099140U discloses a sheet metal cutting device, including a frame, a cutting device, and a limiting plate. The frame includes a worktable, and the cutting device includes a cutting blade disposed below the worktable and at least partially extending through the top surface of the worktable. The limiting plate is disposed on the top surface of the worktable along the cutting direction of the cutting blade and can move towards or away from the cutting blade. The sheet metal cutting device also includes a corner-end limiting component disposed on the limiting plate and slidable along the limiting plate. The corner-end limiting component includes a limiting groove with a preset included angle for the corner end of the sheet metal to be cut to abut. The corner-end limiting component can abut the corner end of the sheet metal to be cut and limit the movement direction of the sheet metal to the cutting direction of the cutting blade, ensuring good limiting effect for cutting the sheet metal at different angles, thereby guaranteeing the straightness and accuracy of the cut and improving the convenience of the cutting operation.

[0003] However, the cutting equipment mentioned above can only cut long plates into short plates of equal width one at a time during use, and cannot cut long plates into short plates of equal width in one go, which will result in slow plate cutting and affect processing efficiency.

[0022] Furthermore, the rotating assembly includes a motor 8, a rotating shaft 9, a first pulley 10, a second pulley 11, and a belt 12. The motor 8 is fixedly installed on the inner wall of one side of the housing 1, and the rotating shaft 9 is rotatably installed on one side of the housing 1. The output shaft of the motor 8 is fixedly installed to one end of the rotating shaft 9.

The belt 12 is sleeved on the first pulley 10 and the second pulley 11. The first pulley 10 is connected to the second pulley 11 through the belt 12. When the motor 8 is started, the output shaft of the motor 8 drives the rotating shaft 9 and the first pulley 10 to rotate. The first pulley 10 drives the second pulley 11, the shaft cylinder 4, the mounting plate 5, and the five annular cutting blades 3 to rotate simultaneously through the belt 12, which can achieve five cuts on the plate and speed up the plate cutting efficiency.

[0023] Furthermore, the adjustment assembly includes a telescopic frame 13, a threaded rod A14, and a knob 15. The telescopic frame 13 is hinged to five mounting plates 5. The threaded rod A14 is rotatably mounted on one side of the shaft cylinder 4. The knob 15 is fixedly mounted on one end of the threaded rod A14. One of the mounting plates 5 is threaded onto the outer wall of the threaded rod A14. By manually turning the knob 15, the threaded rod A14 is rotated. The rotation of the threaded rod A14 causes one mounting plate 5 and the annular cutting blade 3 to move to the left or right, changing the spacing between the five annular cutting blades 3. This facilitates cutting the sheet metal to the required width and improves the efficiency of the equipment.

[0024] Furthermore, the pressing assembly includes a plate frame 16, a movable rod 17, a roller frame 18, a pressure roller 19, and a spring 20.

[0027] Furthermore, the mounting plate 5 located on the far left is fixedly installed on one side of the movable opening.

[0028] Working principle: By manually turning knob 15, knob 15 drives threaded rod A14 to rotate. The rotation of threaded rod A14 drives a mounting plate 5 and annular cutting blade 3 to move to the left or right. Due to the telescopic frame 13, the distance between the five mounting plates 5 and annular cutting blades 3 can be adjusted while the mounting plates 5 and annular cutting blades 3 are moving, changing the cutting width of the annular cutting blade on the board. By starting motor 8, the output shaft of motor 8 drives rotating shaft 9 and first pulley 10 to rotate. First pulley 10 drives second pulley 11, shaft cylinder 4, mounting plate 5 and annular cutting blade 3 to rotate through belt 12. The board is placed on top of worktable 2 and then pushed backward. During the movement, the board is pushed between worktable 2 and pressure roller 19. Through the spring 20 pushing roller frame 18 and pressure roller 19, pressure roller 19 can press the board. As the board moves backward, the board comes into contact with annular cutting blade 3, so that the high-speed rotating annular cutting blade 3 cuts the board.

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.
