Technical Field

[0001] This utility model relates to the field of embroidery technology, specifically to a rope-cutting device and an embroidery machine. Background Technology

[0002] A rope embroidery device is an auxiliary device that works in conjunction with an embroidery machine. The device supplies thicker rope threads to the fabric, and the embroidery machine then embroiders finer threads onto the fabric. The rope threads are then tied to the fabric using the finer threads, thus enriching the fabric pattern. Currently, there are various rope-cutting devices for computerized embroidery machines, such as patent 202110975677.7, which describes a rope-cutting device and a rope embroidery machine. This device can be combined with the control of existing embroidery machines to quickly and accurately cut the embroidery rope according to the rope embroidery process.

[0003] However, this mechanism is relatively complex and has a high cost due to its motor-driven transmission, which cannot meet the actual needs of most customers. Utility Model Content

[0006] Furthermore, the rope-cutting assembly also includes a rope-cutting cylinder, the output telescopic shaft of which is connected to the moving blade to drive the moving blade to cooperate with the fixed blade to cut the rope.

[0007] Furthermore, the rope-cutting assembly also includes an intermediate connector, which is used to connect the output telescopic end of the rope-cutting cylinder and the moving blade, and to convert the output telescopic motion of the rope-cutting cylinder into the rotational motion of the moving blade.

[0008] Furthermore, one end of the intermediate connector has two vertically formed connecting holes, and two bolts pass through one connecting hole to be fixedly connected to the moving blade. The diameter of the bolts is smaller than the diameter of the connecting holes, so that one end of the intermediate connector is connected to the moving blade for a limited movement. The other end of the intermediate connector is hinged to the output telescopic shaft of the rope-cutting cylinder.

[0009] Furthermore, a limiting groove is provided on the lower side of the end of the intermediate connector that is connected to the moving blade, and the lower opening of the connecting hole is opened in the limiting groove. The moving blade extends into the limiting groove to connect with the intermediate connector. The limiting groove is used to restrict the moving blade from rotating relative to the intermediate connector.

[0010] Furthermore, the rotary lifting assembly is a rotary telescopic cylinder, which is positioned downwards, and the rope cutting assembly is installed at the output shaft of the rotary telescopic cylinder.

[0011] Furthermore, the rope-cutting device also includes a first base, on which the rotary lifting assembly is mounted, and the entire rope-cutting device is also fixedly mounted to the external structure via the first base.

[0024] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0025] Please see Figure 1 and Figure 2 A rope-cutting device according to a specific embodiment of the present invention includes a rope-cutting component 1 and a rotary lifting component 2. The rotary lifting component 2 is a rotary lifting cylinder, which has both rotational and lifting functions. The rotary lifting component 2 is vertically arranged, and a second base 4 is fixedly arranged at the output shaft end of the rotary lifting component 2. The rope-cutting component 1 is installed on the second base 4. The rotary lifting component 2 drives the second base 4 to rotate and lift, thereby driving the rope-cutting component 1 to rotate and lift to the position of the rope to cut the rope, or to move and reset to the initial position.

[0026] In this embodiment, the rope-cutting assembly 1 includes a movable blade 11 and a fixed blade 12 that are hinged to each other. The movable blade 11 and the fixed blade 12 cross each other and are hinged together at the intersection and overlap position, so that the clamping area at one end of the blades becomes the rope-cutting area. Alternatively, a technician can rotate the lifting assembly 2 to drive the rope-cutting assembly 1 to rotate and move, so that the rope-cutting area of ​​the rope-cutting assembly 1 can be actively moved to a position that can encompass the rope, and then further control the relative rotation of the movable blade 11 and the fixed blade 12 to cut the rope.

[0027] In this embodiment, the rotary lifting assembly 2 is fixedly installed on the first base 3, and the rotary lifting assembly 2 is fixedly installed on the corresponding structural component of the embroidery machine through the first base 3.

[0028] Further, please refer to Figure 1 and Figure 2 In this embodiment, to achieve automatic rope cutting, a rope cutting cylinder 13 is also horizontally fixedly installed on the second base 4. The output telescopic shaft of the rope cutting cylinder 13 and the moving blade 11 are connected to each other through an intermediate connector 14. The intermediate connector 14 is movably connected to the moving blade 11 and 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 moving blade 11 through the intermediate connector 14, thereby driving the moving blade 11 to cooperate with the fixed blade 12 to cut the rope.

[0029] For details, please refer to Figure 2 , refer to Figure 2 As shown, the intermediate connector 14 is a "Z"-shaped connecting strip structure and is relatively small in size. The left end of the intermediate connector 14 is provided with a hinge hole, which is connected to the output telescopic shaft of the rope cutting cylinder 13. The middle and right ends of the intermediate connector 14 are each provided with a connecting hole 141. The left end of the moving blade 11 is provided with two screw holes. Each of the two connecting holes 141 is provided with a bolt. Each bolt passes through a connecting hole 141 to be threadedly connected to the corresponding screw hole on the moving blade 11. At the same time, the diameter of the two bolts is smaller than the diameter of the corresponding connecting hole 141.

[0030] In response, when technicians use bolts to connect the intermediate connector 14 and the moving blade 11, they only need to be careful not to overtighten the bolts, so as to avoid the nut end of the bolt engaging with the moving blade 11 to clamp the intermediate connector 14. In this way, when the output telescopic shaft of the rope cutting cylinder 13 extends or retracts, the intermediate connector 14 can effectively drive the moving blade 11 to rotate accordingly. The intermediate connector 14 can also move relative to the moving blade 11 to eliminate the problem of mismatch between the linear movement trajectory of the output telescopic shaft end and the circular movement trajectory of the left end of the moving blade 11.

[0031] Furthermore, to prevent the intermediate connector 14 from being too flexible, causing the moving blade 11 to fail to immediately respond to the operation of the rope-cutting cylinder 13; please refer to... Figure 2 ,by Figure 2 Taking the orientation shown as an example, in this embodiment, a limiting groove 142 is also provided on the lower surface of the left end of the intermediate connector 14. The width of the limiting groove 142 is equivalent to the width of the left end of the moving knife 11, and the lower ends of the two connecting holes 141 extend into the limiting groove 142.

[0032] Thus, when the rope-cutting cylinder 13 drives the moving blade 11 to rotate through the intermediate connector 14, under the limiting action of the limiting groove 142, although the intermediate connector 14 and the moving blade 11 can only eliminate the problem of trajectory mismatch by moving in a straight line relative to each other, the extension and retraction action of the output extension shaft of the rope-cutting cylinder 13 can drive the moving blade 11 to rotate in the first time through the intermediate connector 14.

[0033] Please see Figure 3 An embroidery machine according to a specific embodiment of the present invention includes any of the rope-cutting devices described in 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.

[0034] Anything not mentioned above applies to existing technologies.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
