[0033] Please combine Figs. 1 to 3 The present embodiment provides a cooling copper roller, which comprises a copper roller body 10 and a cutting structure 20.
[0034] The cutting structure 20 is arranged on the surface of the copper roller body 10, and the cutting structure 20 has a protruding part 21 which protrudes outward from the surface of the copper roller body 10, and the protruding part 21 is used to make the metal material break to form a metal wire belt during contact with the metal material.
[0035] Specifically, since the metal material has strong brittleness under extremely cold conditions, in the process of cooling the copper roller to rotate rapidly, because of the existence of the cutting structure 20, the end of the protruding part 21 of the cutting structure 20 will generate a large shear force with the ribbon, causing the metal wire to break, thereby obtaining a metal wire ribbon with controllable length.
[0036] In some alternative embodiments, the cutting structure 20 can be connected with the copper roller body 10 by clamping (as shown in Fig. 1 In other alternative embodiments, the cutting structure 20 can be connected with the copper roller body 10 by welding (as shown in Fig. 2
[0037] As for clamping, the surface of the copper roller body 10 is provided with an inwardly recessed clamping groove 11, and the cutting structure 20 is clamped in the clamping groove 11.
[0038] In some preferred embodiments, the width of the clamping groove 11 gradually decreases in the direction extending outwardly from the surface of the copper roller body 10. Exemplarily, the clamping groove 11 can have a trapezoidal shape in the plane parallel to the end face of the copper roller body 10, and more preferably a non-right-angled trapezoidal shape.
[0039] By providing the clamping groove 11 in the above form, effective limiting and fixing of the cutting structure 20 can be achieved.
[0040] Further, detachable fixing members can also be provided on the two end faces of the copper roller body 10 to prevent the cutting structure 20 from being detached from the two end faces, so as to achieve close cooperation between the cutting structure 20 and the copper roller body 10 without loosening, and the cutting structure 20 will not fall off even when rotating at high speed.
[0041] In alternative embodiments, the cutting structure 20 is a rack. Exemplarily, the rack has a triangular cross section. The cross section is the plane of the rack parallel to the end face of the copper roller body 10 under use conditions. In addition, the rack can also have other shapes of cross section, but the end of the rack protruding outwardly from the copper roller body 10 has only one sharp end 22.
[0042] The copper roller body 10 has opposite first and second ends 12 and 13 (as shown in Fig. 3 The distance between the first and second ends 12 and 13 of the copper roller body 10 is defined as the length of the copper roller body 10.
[0043] In some alternative embodiments, the connection region of the rack with the copper roller body 10 extends from one end of the copper roller body 10 (such as the first end 12) to the other end of the copper roller body 10 (such as the second end 13), that is, the connection length of the rack with the roller body is equal to the length of the copper roller body 10.

Exemplarily, the multiple cutting structures 20 can be distributed along the circumference of the cooling copper roller at equal intervals, or can be distributed along the circumference of the cooling copper roller at unequal intervals.
[0047] When the multiple cutting structures 20 are distributed along the circumference of the cooling copper roller at equal intervals, the prepared fiber filaments or strips have uniform lengths. When the multiple cutting structures 20 are distributed along the circumference of the cooling copper roller at unequal intervals, for example, the intervals between the adjacent two cutting structures 20 are unequal, at this time, each batch of prepared materials will present different lengths according to the intervals between the cutting structures 20, which is beneficial to form the distribution state of the fiber filaments with different lengths.
[0048] In some optional embodiments, taking the diameter of the copper roller body 10 as 400 mm for example, when the multiple cutting structures 20 are distributed along the circumference of the cooling copper roller at equal intervals, if the number of the cutting structures 20 is two, the interval between the two cutting structures 20 can be 630 mm; if the number of the cutting structures 20 is three, along the same direction, the interval between the adjacent two cutting structures 20 can be 420 mm; if the number of the cutting structures 20 is four, along the same direction, the interval between the adjacent two cutting structures 20 can be 320 mm; if the number of the cutting structures 20 is five, along the same direction, the interval between the adjacent two cutting structures 20 can be 250 mm; if the number of the cutting structures 20 is six, along the same direction, the interval between the adjacent two cutting structures 20 can be 210 mm; if the number of the cutting structures 20 is fourteen, along the same direction, the interval between the adjacent two cutting structures 20 can be 90 mm.
[0049] Similarly, taking the diameter of the copper roller body 10 as 400 mm as an example, when the plurality of cutting structures 20 are distributed at non-equidistant intervals along the circumferential direction of the cooling copper roller, taking the number of the cutting structures 20 as 7 as an example, along the same direction, the interval between the first cutting structure 20 and the second cutting structure 20 can be 10 mm, the interval between the second cutting structure 20 and the third cutting structure 20 can be 40 mm, the interval between the third cutting structure 20 and the fourth cutting structure 20 can be 80 mm, the interval between the fourth cutting structure 20 and the fifth cutting structure 20 can be 120 mm, the interval between the fifth cutting structure 20 and the sixth cutting structure 20 can be 200 mm, and the interval between the sixth cutting structure 20 and the seventh cutting structure 20 can be 300 mm.
[0050] In addition, copper roller bodies 10 with other diameters can also be used according to actual needs.
