DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0027] Example 1:

[0028] A rotary cutting device for metal wire, comprising a rotary cutting mechanism and a power source, such as Figure 1 、 2As shown in Figure 3, the rotary cutting mechanism includes a rotary knife seat 1 and a rotary cutter 2. A power seat is provided between the rotary knife seat 1 and the power source. The power seat 16 is provided with a mounting hole III. A power shaft hole and a fixing groove 3 are provided on the rotary knife seat 1. A clamping slit 6 and a fastening through hole are provided on the side wall of the rotary knife seat 1. The fastening through hole cooperates with the fastener I7 to adjust the clamping slit 6. The clamping slit 6 is communicated with the power shaft hole. The power source includes a reducer 10 and a motor 15. The power shaft 11 of the reducer 10 passes through the mounting hole III and the power shaft hole to connect to the rotary knife seat 1. A limiting slot I is provided on the edge of the power shaft hole. A limiting slot II is provided at the position of the power shaft of the power source relative to the limiting slot I. The limiting clip 14 is embedded between the limiting slot I and the limiting slot II, and the side wall of the limiting clip is tightly connected to the side wall of the limiting slot I and the side wall of the limiting slot II. The rotary knife seat 1 rotates with the power shaft.

[0029] The rotary cutter 2 is partially installed in the fixing groove 3. A mounting hole I is provided on the rotary cutter 2, and a mounting hole II is provided in the fixing groove 3. The rotary cutter 2 is connected to the rotary cutter holder 1 through the fastener II17 through the mounting hole I and the mounting hole II. The rotary cutter 2 can also be integrally formed with the rotary cutter holder 1.

[0030] A wire-passing bottom blade holder 8 is provided opposite the rotary cutter 2. A wire-passing bottom blade 9 is provided opposite the rotary cutter 2, through which the metal wire passes. The rotary cutter 2 rotates against the outer wall of the wire-passing bottom blade 9 to cut the wire, with the rotary cutter 2 acting as the active cutter and the wire-passing bottom blade 9 acting as the passive cutter. The rotary cutter 2 rotates with the rotary cutter holder 1 to cut the metal wire, and when the rotary cutter 2 rotates 180° from the cutting position to the cutting position relative to the rotary cutter 2, there is a gap between the metal wire and the inner wall of the rotary cutter.

[0031] When in use, start the motor and the reducer, the power shaft drives the rotary knife seat to rotate, the rotary knife seat drives the rotary cutter to rotate, the metal wire passes through the wire bottom knife of the wire bottom knife seat, and is cut by the rotary cutter. When the rotary cutter rotates 180 degrees from the cutting position to the cutting relative position, there is a gap between the metal wire and the inner wall of the rotary cutter, that is to say, after the rotary cutter cuts the metal wire, the metal wire will be temporarily suspended from feeding. As long as it is ensured that when the rotary cutter rotates 180 degrees to the cutting relative position, the metal wire has not reached the cutting relative position, providing space for the rotary cutter to pass through, thereby preventing the rotary cutter from being blocked by the metal wire.

[0032] Example 2:

[0033] Different from the above embodiment 1, Figure 4 、 5As shown, two rotary cutters are provided on the rotary cutter seat 1, and the two rotary cutters are arranged opposite to each other. The first rotary cutter 4, the second rotary cutter 5 and the rotary cutter seat 1 adopt an integrally formed structure, and of course it can also be an assembled structure. When the first rotary cutter 2 moves from the cutting position to the cutting relative position, the second rotary cutter 2 is located at the cutting position and above the metal wire, and the first rotary cutter 2 is located below the metal wire and the metal wire extends beyond the first rotary cutter 2.

[0034] When in use, start the motor and the reducer, the power shaft drives the rotary knife seat to rotate, and the rotary knife seat drives the two to rotate. The metal wire passes through the wire bottom knife of the wire bottom knife seat and is cut by the first rotary cutter. Since the second rotary cutter is relative to the first rotary cutter, when the first rotary cutter reaches the cutting relative position, the second rotary cutter reaches the cutting position to cut the metal wire. There is no problem that the rotary cutter is blocked by the metal wire and cannot pass through.

[0035] Example 3:

[0036] A rotary cutting mechanism, such as Figure 6 As shown, it includes a rotary knife seat 1 and a rotary cutter 2. The rotary cutter 2 is arranged on the rotary knife seat 1. When it is specifically set, a fixing groove can be set on the rotary knife seat, and the rotary cutter 2 is partially installed in the fixing groove 3. A mounting hole I is provided on the rotary cutter 2, and a mounting hole II is provided in the fixing groove 3. The rotary cutter 2 is connected to the rotary knife seat 1 through the fastener II17 through the mounting hole I and the mounting hole II. Of course, the rotary cutter 2 and the rotary knife seat 1 can also be integrally formed.

[0037] The rotary cutter 2 rotates along with the rotary cutter holder 1 to cut the metal wire, and when the rotary cutter 2 rotates 180 degrees from the cutting position to the cutting relative position, there is a distance between the metal wire and the inner side wall of the rotary cutter.

[0038] The rotary tool holder 1 is provided with a power shaft hole 11 , a clamping slit 6 and a fastening through hole. The clamping slit 6 is communicated with the power shaft hole 11 , and the fastening through hole cooperates with a fastener I 7 to adjust the clamping slit 6 .

[0039] Example 4:

[0040] A rotary cutting mechanism, such as Figure 7-8 As shown, it includes a rotary cutter seat 1 and two rotary cutters 2. The rotary cutters 2 are arranged on the rotary cutter seat 1, and the two rotary cutters 2 are arranged opposite to each other.

[0041] In the specific setting, a fixing groove can be provided on the rotary cutter holder, the rotary cutter 2 is partially installed in the fixing groove 3, and a mounting hole I is provided on the rotary cutter 2, and a mounting hole II is provided in the fixing groove 3. The rotary cutter 2 is connected to the rotary cutter holder 1 through the mounting hole I and the mounting hole II by a fastener II17. Of course, the rotary cutter 2 and the rotary cutter holder 1 can also be integrally formed.

[0042] When the first rotary cutter 2 moves from the cutting position to the cutting relative position, the second rotary cutter 2 is located at the cutting position and above the metal wire, the first rotary cutter 2 is located below the metal wire and the metal wire extends beyond the first rotary cutter 2.

[0043] The rotary tool holder 1 is provided with a power shaft hole 11 , a clamping slit 6 and a fastening through hole. The clamping slit 6 is communicated with the power shaft hole 11 , and the fastening through hole cooperates with a fastener I 7 to adjust the clamping slit 6 .
