[0065] Working principle:

[0066] When the electromagnetic wire cutting device is in use, first, the electromagnetic wire is passed through the cutting device housing 1, and the electromagnetic wire is made to fit on the length measuring component 5. As the electromagnetic wire moves, the length measuring component 5 can calculate the length of the electromagnetic wire. After reaching the specified length, the electromagnetic wire stops conveying, and the second motor 7 is started at this time. The output end of the second motor 7 drives the turntable 6 to rotate, and the turntable 6 drives the first cylindrical pin to rotate at the same time. The first cylindrical pin slides with the first slide groove to make the slot plate 8 move vertically upward, and the slot plate 8 drives the support plate 10 to move through the connecting piece 9.

After the cutting is completed, the third motor 19 is started, and the output end of the third motor 19 drives the screw 18 to rotate. The screw 18 will cause the nut 20 to move along the extension direction of the screw 18. The nut 20 drives the cleaning component 21 to move. The cleaning component 21 will push the debris to the notch at the top of the lower shell, so that the debris falls into the debris collection box 17. Manual cleaning is no longer required, which is convenient for cleaning and completes the use of this device.
