[0030] During use, the staff first places the piece of meat to be cut on the L-shaped placement plate 13, and then clamps and fixes the piece of meat through the lower fixing plate 18 and the upper fixing plate 19, and then starts the drive motor 8 to rotate the lower rotating wheel 5, thereby driving the upper rotating wheel 4 and the saw blade 6 to rotate, and then starts the second guide rail 15 to make the slider of the second guide rail 15 move to the left inside the movable hole 14, so that the connecting frame 16, the pushing plate 17 and the piece of meat move to the left, so that the piece of meat contacts the baffle 10, and then starts the first guide rail 12 to make the slider move backward, thereby driving the L-shaped placement plate 13 and the piece of meat to move backward, and the piece of meat is cut by the saw blade 6.

[0031] The chassis 1, saw blade 6, baffle 10, first guide rail 12, L-shaped placement plate 13, second guide rail 15, and push plate 17 facilitate workers to automatically cut meat blocks, thereby improving the flexibility and practicality of the device and reducing manual operation, thereby reducing the chance of manual contact with the saw blade 6, thereby reducing the risk of work-related injuries and helping to improve the safety of the overall working environment.

[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, a first pressure sensor 20 is fixed to the right side of the baffle 10, and the first pressure sensor 20 is electrically connected to the PLC controller.
