[0041] like Figure 1-11 As shown, a rope cutting mechanism 40 provided according to the first aspect of the utility model includes: a scissors assembly 41 and a first telescopic assembly 43.

[0042] The scissor assembly 41 includes a movable knife arm 412 and a fixed knife arm 411. The movable knife arm 412 moves along a straight line to approach or move away from the fixed knife arm 411. The first telescopic assembly 43 enables the scissor assembly 41 to approach or move away from the table of the computer embroidery machine.

[0043] It should be noted that, in practical applications, the rope cutting mechanism 40 can be applied to a rope embroidery device, the rope cutting mechanism 40 can be applied to a ribbon embroidery device, and so on.

[0044] This embodiment is described by taking the rope cutting mechanism 40 applied to a rope embroidery device as an example.

[0045] like Figure 5-Figure 7 As shown, a fixed knife blade 4111 is provided on the fixed knife arm 411, and a movable knife blade 4121 is provided on the movable knife arm 412. The movable knife blade 4121 and the fixed knife blade 4111 are arranged opposite and spaced apart. The movable knife arm 412 approaches the fixed knife arm 411, and the movable knife blade 4121 contacts the fixed knife blade 4111 to cut the rope. The current position of the movable knife arm 412 is defined as the rope cutting position, as shown in FIG. Figure 6 The movable knife arm 412 is away from the fixed knife arm 411, and the movable knife blade 4121 is spaced from the fixed knife blade 4111 to prepare for the next shearing, and the current position of the movable knife arm 412 is defined as the initial position, such as Figure 5Then the movable knife arm 412 moves toward the fixed knife arm 411 to have a rope cutting position and an initial position, and the movable knife arm 412 reciprocates between the rope cutting position and the initial position.

[0046] The first telescopic component 43 can be telescopic in a vertical direction, and the first telescopic component 43 can be telescopic in a first inclined direction inclined relative to the vertical direction, which is not limited in this embodiment.

[0047] In actual application, after the rope embroidery device has finished embroidering the pattern on the cloth, the rope cutting mechanism 40 cuts the rope, and the rope end remaining on the cloth may be too long, affecting the pattern presentation effect of the rope embroidery. Based on this, the present embodiment uses the first telescopic component 43 to make the scissor component 41 close to or away from the table of the computer embroidery machine, that is, the distance between the scissor component 41 and the cloth on the table can be adjusted, and then the scissor component 41 cuts the rope, and the rope end remaining on the cloth can be controlled, so that the length of the rope end remaining on the cloth meets the requirements, thereby improving the pattern presentation effect of the rope embroidery.

[0048] In some embodiments of the present invention, the fixed knife blade 4111 is in a straight line shape, the movable knife blade 4121 is in a V-shape, a U-shape, and an arc shape, and the opening of the movable knife blade 4121 faces the fixed knife blade 4111 .

[0049] In a specific embodiment, Figure 7 As shown, the fixed blade 4111 can be straight, and the movable blade 4121 is V-shaped, and the V-shaped opening of the movable blade 4121 faces the fixed blade 4111. The movable blade 4121 moves toward the fixed blade 4111, and the movable blade 4121 and the fixed blade 4111 work together so that the rope is clamped at the V-shaped bottom of the movable blade 4121, limiting the freedom of the rope. That is to say, before the movable blade 4121 cuts the rope, the rope is clamped at the V-shaped bottom of the movable blade 4121 by the movable blade 4121 and the fixed blade 4111, and the rope is in a static state. Then, the movable blade 4121 continues to move toward the fixed blade 4111, thereby cutting the rope.

[0050] In this way, before the rope is cut, the rope is clamped by the passive knife blade 4121 and the fixed knife blade 4111 at the V-shaped bottom of the movable knife blade 4121, and the rope is in a relatively static state, which helps the movable knife blade 4121 to cut the rope, ensures that the movable knife blade 4121 can cut the rope at one time, and improves the rope cutting effect of the scissors assembly 41.

[0051] Of course, it is understandable that the movable knife blade 4121 can be U-shaped or arc-shaped.

[0052] Furthermore, in some embodiments, the fixed knife blade 4111 is one of a V-shape, a U-shape and an arc shape, the opening of the fixed knife blade 4111 faces the movable knife blade 4121, and the movable knife blade 4121 is a straight blade.

[0055] It should be noted that the movable knife arm 412 and the fixed knife arm 411 are both arranged horizontally, and the movable knife arm 412 moves toward the fixed knife arm 411 to have a rope cutting position and an initial position. The movable knife arm 412 and the fixed knife arm 411 are arranged up and down, and the surface of the movable knife arm 412 facing the fixed knife arm 411 and the surface of the fixed knife arm 411 facing the movable knife arm 412 are located at the same height, that is, the surface of the movable knife arm 412 facing the fixed knife arm 411 and the surface of the fixed knife arm 411 facing the movable knife arm 412 are located on the same horizontal plane.

[0056] A straight fixed blade 4111 arranged in a slope is formed on the surface of the fixed blade arm 411 facing away from the movable blade arm 412, and the cutting edge of the fixed blade 4111 is located on the surface of the fixed blade arm 411 facing the movable blade arm 412; a V-shaped movable blade 4121 arranged in a slope is formed on the surface of the movable blade arm 412 facing away from the fixed blade arm 411, and the cutting edge of the movable blade 4121 is located on the surface of the movable blade arm 412 facing the fixed blade arm 411. In this arrangement, the cutting edge of the fixed blade 4111 and the cutting edge of the movable blade 4121 are located at the same height, and there is no height difference between the movable blade 4121 and the fixed blade 4111, which is helpful for cutting the rope.

[0057] In addition, the inclination direction of the fixed knife blade 4111 is parallel to the inclination direction of the movable knife blade 4121. Such an arrangement facilitates processing and helps reduce production costs.

[0058] Of course, it is understood that in some embodiments, such as Fig.10 and Fig.11As shown, the movable knife arm 412 and the fixed knife arm 411 are both arranged in a preset direction inclined relative to the horizontal direction.

The fixed blade 4111 is fixedly arranged at an opening of the guide groove 4141, and the movable blade 4121 is arranged at the other opening of the guide groove 4141, wherein the movable end of the third telescopic assembly 413 is connected to the movable blade 4121, and then the movable blade 4121 moves along a straight line toward and away from the fixed blade arm 411 to have a rope cutting position and an initial position.

[0061] The support plate 415 is connected to the guide groove 4141, and a pressing member 416 is provided on the support plate 415, and the pressing member 416 is a bolt. The bolt is threadedly connected to the support plate 415, and then one end of the bolt can press the movable knife arm 412. In this way, by adjusting the upper and lower positions of the bolt, the force of the bolt pressing the movable knife arm 412 is adjusted, which helps the surface of the movable knife arm 412 facing the fixed knife arm 411 and the surface of the fixed knife arm 411 facing the movable knife arm 412 to be located on the same horizontal plane, or the surface of the movable knife arm 412 facing the fixed knife arm 411 and the surface of the fixed knife arm 411 facing the movable knife arm 412 are located on the same inclined plane, the cutting edge of the fixed knife blade 4111 and the cutting edge of the movable knife blade 4121 are located at the same height, and there is no height difference between the movable knife blade 4121 and the fixed knife blade 4111, so as to ensure that the rope is cut in one time.
