[0025] like Figure 3 As shown, the reel system 3 includes a motor 3-1, a coupling 3-2, a reel bearing box 3-3, and a reel 3-4. The coupling 3-2 is arranged in the reel bearing box 3-3 and connected to the reel bearing box 3-3. The output shaft of the motor 3-1 passes through the reel bearing box 3-3 and is connected to the coupling 3-2. The reel 3-4 is connected to the reel bearing box 3-3. In this embodiment, the reel 3-4 has a diameter of 250 mm and a length of 120 mm, thereby ensuring that the diamond wire wheel has small jitter under high-speed operation and the cutting line has small bending degree.
[0026] like Figure 4 As shown, the cable arrangement system 4 includes a cable arrangement linear module 4-1, a connection balance component 4-2, a fixed seat component 4-3, and a guide wheel component 4-4. The cable arrangement linear module 4-1 is arranged on the main frame 1, and one end of the connection balance component 4-2 is fixedly connected to the cable arrangement linear module 4-1, and the other end is connected to the guide wheel component 4-4 through the fixed seat component 4-3; Figure 5 As shown, the guide wheel assembly 4-4 includes a fixed wheel 4-33 fixedly connected to the connecting balance assembly 4-2, the fixed wheel 4-33 is provided with a guide wheel shaft 4-5, and the guide wheel shaft 4-5 is evenly provided with three rows of pressure sensors 4-6; and the guide wheel assembly 4-4 is arranged on the guide wheel shaft 4-5; in the present embodiment, two three-row pressure sensors 4-6 are distributed in each row; the pressure sensor 4-6 cooperates with the correction system control to realize the uniform and stable arrangement of the wire on the reel, and to reduce the vibration and wire breakage rate of the diamond wire to a limited extent, so as to provide a guarantee for the high-speed thinning of the multi-wire cutting machine.
