[0041] It should be noted that the number of main rollers 21 is not limited to the above three, for example, it can also be two or four, etc. Such adjustment and change of the specific number of main rollers 21 does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0042] Preferably, as shown in Figure 2 The wire cutting machine of the present application further comprises a broken wire detection device mounted on the cutting frame 1, which can detect the breakage of the cutting wire on the main roller 21.

[0047] By setting the pre-tightening mechanism 32, the detection line 6 has an initial tension (the initial tension is the pre-tightening force), so that the detection line 6 is more easily broken, which is beneficial to avoid the situation that the broken cutting line is not detected.

[0048] Exemplarily, the detection line 6 is cotton thread, if the breaking force of the cotton thread is 6N, the pre-tightening mechanism 32 can make the cotton thread have a pre-tightening force of 4N, and the cutting line can break the cotton thread when the force acting on the cotton thread is not less than 2N.
