The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0020] See also Figure 1 and Figure 2A rope cutting device according to a specific embodiment of the present invention comprises a rope cutting assembly 1 and a rotating lifting assembly 2. The rotating lifting assembly 2 is a rotating lifting cylinder. The rotating lifting assembly 2 has both rotating motion function and lifting motion function. The rotating lifting assembly 2 is vertically arranged. A second base 4 is fixedly arranged at the output shaft end of the rotating lifting assembly 2. The rope cutting assembly 1 is installed on the second base 4. The rotating lifting assembly 2 drives the second base 4 to rotate and lift, so as to drive the rope cutting assembly 1 to rotate and lift to the position where the rope is located to cut the rope, or move and reset to the initial position.

[0021] In this embodiment, the rope cutting assembly 1 includes a movable knife 11 and a fixed knife 12 which are hinged to each other. The movable knife 11 and the fixed knife 12 cross each other and are hingedly connected at the crossing and overlapping position, so that the clamping area at one end of the two becomes the rope cutting area; in this regard, the technician can also drive the rope cutting assembly 1 to rotate and move by rotating the lifting assembly 2, so that the rope cutting area of ​​the rope cutting assembly 1 actively moves to a position that can encompass the rope line, and then further control the relative rotation of the movable knife 11 and the fixed knife 12, thereby cutting the rope line.

[0022] In this embodiment, the rotary lifting assembly 2 is fixedly mounted on the first base 3, and the rotary lifting assembly 2 is fixedly mounted on a corresponding structural component of the embroidery machine through the first base 3.

[0023] For further information, see Figure 1 and Figure 2 In this embodiment, in order to realize the automatic rope cutting action, a rope cutting cylinder 13 is also fixedly installed horizontally on the second base 4. The output telescopic shaft of the rope cutting cylinder 13 and the movable knife 11 are connected to each other through an intermediate connecting member 14. The intermediate connecting member 14 is movably connected to the movable knife 11 and is hinged to the output telescopic shaft of the rope cutting cylinder 13. The linear telescopic motion of the output telescopic shaft of the rope cutting cylinder 13 can be effectively converted into the rotational motion of the movable knife 11 through the intermediate connecting member 14, thereby driving the movable knife 11 to cooperate with the fixed knife 12 to cut the rope.

[0024] For details, please refer to Figure 2 , refer to Figure 2 In the orientation shown, the intermediate connecting member 14 is a "Z"-shaped connecting strip structure with a relatively small size. A hinge hole is provided at the left end of the intermediate connecting member 14, and the left end of the intermediate connecting member 14 is hingedly connected to the output telescopic shaft of the rope-cutting cylinder 13. A connecting hole 141 is provided at the middle and right end of the intermediate connecting member 14 respectively. Two screw holes are provided at the left end of the movable knife 11 respectively, and a bolt is provided in each of the two connecting holes 141. The two bolts respectively pass through a connecting hole 141 to be threadedly connected to the corresponding screw holes on the movable knife 11 respectively; at the same time, the diameters of the two bolts are smaller than the diameters of the corresponding connecting holes 141.

[0025] In this regard, when the technician uses bolts to connect the intermediate connector 14 and the movable knife 11, he only needs to be careful not to over-tighten the bolts to avoid the nut end of the bolts cooperating with the movable knife 11 to clamp the intermediate connector 14; in this way, when the output telescopic shaft of the rope-cutting cylinder 13 is extended or retracted accordingly, the intermediate connector 14 can effectively drive the movable knife 11 to rotate accordingly, and the intermediate connector 14 can also move relative to the movable knife 11 to eliminate the problem of incompatibility between the linear movement trajectory of the shaft end of the output telescopic shaft and the circular motion trajectory of the left end of the movable knife 11.

[0026] Further, in order to prevent the problem that the movable knife 11 cannot immediately respond to the operation of the rope cutting cylinder 13 due to the excessive flexibility of the intermediate connecting member 14; Figure 2 ,by Figure 2 Taking the shown orientation as an example, in this embodiment, a limiting groove 142 is further provided on the lower surface of the left end of the intermediate connecting member 14 , the groove width of the limiting groove 142 is equivalent to the width of the left end portion of the movable knife 11 , and the lower ends of the two connecting holes 141 are extended to be provided in the limiting groove 142 .

[0027] In this way, when the rope-cutting cylinder 13 drives the movable knife 11 to rotate through the intermediate connecting piece 14, under the limiting action of the limiting groove 142, although the intermediate connecting piece 14 and the movable knife 11 can only move relative to each other in a straight line to eliminate the trajectory mismatch problem, the telescopic action of the output telescopic shaft of the rope-cutting cylinder 13 can drive the movable knife 11 to rotate through the intermediate connecting piece 14 at the first time.

[0028] See also Figure 3 An embroidery machine according to a specific embodiment of the present invention comprises a rope cutting device according to any one of the above embodiments, the rope cutting device is vertically installed in the rear area of ​​the embroidery machine, and the rope used for embroidery in the embroidery machine passes through the rotation path of the rope cutting assembly 1.

[0029] A rope cutting control method according to a specific embodiment of the present invention adopts any of the rope cutting devices described above, and the specific steps include: A rope cutting control command is issued to the rotary lifting assembly 2. After receiving the rope cutting control command, the rotary lifting assembly 2 starts to operate, driving the rope cutting assembly 1 to move downward to a first height position, and then driving the rope cutting assembly 1 to rotate to a second horizontal position with a rope line, and making the rope line just within the cutting area of ​​the moving knife 11 and the fixed knife 12; The rope cutting assembly 1 is controlled to cut the rope, and after the rope is cut, a reset control command is issued. After receiving the reset control command, the rotating lifting assembly 2 drives the rope cutting assembly 1 to rotate from the second horizontal position to the first height position, and then rises from the first height position to the initial height position, and then stops.

[0030] Specifically, in the present embodiment, when the rope cutting assembly 1 is located at the initial height position, the rope cutting assembly 1 can avoid the embroidery frame structure of the embroidery, so as not to block the embroidery frame; when it is necessary to cut the rope thread, the embroidery has been woven, and the embroidery frame is far away from the rope cutting device. The rope cutting assembly 1 can automatically cut the rope thread according to the above steps, and then automatically reset to facilitate the embroidery to move relative to another embroidery frame and pass under the rope cutting device.

[0031] Anything not mentioned above is applicable to the prior art.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
