[0035] Then, first, raise each conveying wheel 38 through the first linear mechanism 32, place a plurality of connecting line raw materials into the first semi-circular groove 12 in sequence, or part of the connecting line raw materials can also be located on the second semi-circular groove 21. In short, it should not exceed the conveying end of the module conveyor 2. Then, lower each conveying wheel 38 through the first linear mechanism 32 so that the conveying wheels 38 contact the connecting line raw materials.

[0036] Then, lower the cross block 43 through the second linear mechanism 42. First, make the limiting block 48 completely fall into the vertical groove 24. At this time, the cutting edge portion 441 still cannot contact the connecting line raw materials. Then, rotate each conveying wheel 38 through each rotating motor 36 until the end portions of the connecting line raw materials contact the limiting block 48.

[0037] Next, the cross block 43 continues to descend, and the cutting edge portion 441 cuts the connecting line raw materials. At the same time, the spring 46 is compressed and the hanging plate 45 descends. After the cutting is completed, the second linear mechanism 42 lifts all the components under its output shaft, and then continues to convey the connecting line raw materials so that the cut connecting lines are pushed into the collection basket 5.

[0038] And so on, continuous cutting of the connecting lines can be carried out.
