[0028] See also Figures 1 to 7 As shown, according to an embodiment of the utility model, a rope cutting device is provided, comprising a housing 1, a driving device 2 and a transmission device 3 adapted to the driving device 2 are arranged on the housing 1, the transmission device 3 has a transmission body 301, a first connecting block 303 is connected to the transmission body 301, so that the first connecting block 303 can reciprocate along the transmission direction of the transmission body 301, the first connecting block 303 is connected to a scissors assembly 5 through a transmission assembly 4, the scissors assembly 5 includes a static knife assembly 501 and a moving knife assembly 502, the transmission assembly 4 has a first motion state and a second motion state, when the transmission assembly 4 is in the first motion state, the static knife assembly 501 and the moving knife assembly 502 move together, when the transmission assembly 4 is in the second motion state, the moving knife assembly 502 approaches the static knife assembly 501. In the prior art, after the rope embroidery is finished, the workers usually cut the transition section or the end rope separately, which is labor-intensive and the wrong cutting and missed cutting often occur. Through the cooperation of the driving device 2 and the transmission device 3, the movement of the transmission component 4 is realized, and the scissors component 5 connected to the transmission component 4 is divided into a moving knife component 502 and a static knife component 501. In the first movement state, the moving knife component 502 and the static knife component 501 move together to the rope position, and the rope is placed between the moving knife component 502 and the static knife component 501. The static knife component 501 hooks the rope and plays a certain fixing role on the rope. In the second movement state, the moving knife component 502 approaches the static knife component 501 to achieve the cutting of the rope, which can reduce the shaking of the rope and achieve a better cutting effect. In addition, by performing mechanical cutting and embroidery work at the same time, the work intensity of manual cutting is reduced, and the occurrence of wrong cutting and missed cutting is effectively avoided.

[0029] In a specific embodiment, the transmission assembly 4 includes a first connecting plate 401 and a second connecting plate 402 connected by an elastic member 403, one end of the first connecting plate 401 is connected to the first connecting block 303, and the other end thereof is connected to the movable knife assembly 502, the second connecting plate 402 is connected to the stationary knife assembly 501, and the second connecting plate 402 is also connected to a limiting member 404, the limiting member 404 is slidably matched with the limiting groove 101 on the shell 1, so that the first connecting plate 401 and the second connecting plate 402 can reciprocate along the first motion trajectory together, the limiting groove 101 structure is adapted to the first motion trajectory, and when the limiting member 404 moves to the front end of the limiting groove 101, the first connecting plate 401 reciprocates along the second motion trajectory. The first connecting plate 401 and the second connecting plate 402 are softly connected by the elastic member 403. When the first connecting block 303 moves forward with the transmission device 3, the first connecting plate 401 also moves forward. Due to the presence of the elastic member 403, the first connecting plate 401 and the second connecting plate 402 move forward together to drive the static knife assembly 501 and the moving knife assembly 502 to move forward at the same time. At this time, the limiting member 404 on the second connecting plate 402 slides in the limiting groove 101. When the limiting member 404 slides to the front end of the limiting groove 101, the second connecting plate 402 stops moving due to the limiting effect. The above is the first movement state of the transmission assembly 4. At this time, the moving knife assembly 502 and the static knife assembly 501 move forward together to the rope position, and the rope is placed between the moving knife assembly 502 and the static knife assembly 501. When the first connecting block 303 continues to move, the first connecting plate 401 continues to move forward. At this time, the elastic member is stretched, and the first connecting plate 401 drives the moving knife assembly 502 to continue to approach the static knife assembly 501 to cut the rope. After the rope cutting is completed, the first connecting block 303 moves back, driving the first connecting plate 401 to move back. At this time, under the pulling force of the elastic member, the first connecting plate 401 and the second connecting plate 402 are reset, and then move together to the starting position. Through the design of this structure, the same driving device 2 is used to complete the two motion states of the moving knife assembly 502 and the static knife assembly 501, and the rope cutting work is successfully completed. The structure is simple, easy to maintain the device, and easy to operate. Compared with the multi-motor driven cutting work of the prior art, the cost is lower. The structure of the limit groove 101 is designed to be compatible with the first motion trajectory of the second connecting plate 402, which can effectively ensure that the scissors assembly 5 moves along a limited route and avoid the problem of motion route deviation.

[0030] Specifically, the driving device 2 is a motor.

[0031] Specifically, the first connection block 303 is connected to the first connection plate 401 through the fifth connection plate 305 .

[0032] In a specific embodiment, the first connecting block 303 has a vertical chute, in which a sliding member 304 is slidably provided, and the sliding member 304 is connected to the first connecting plate 401. Since the rope cutting device often needs to be used together with the rope embroidery machine, due to reasons such as the installation position or the mechanical structure design position, some mechanical structures are effectively avoided, resulting in the transmission assembly 4 and the scissors assembly 5 needing to move along a complex running trajectory, that is, including movement in the X and Y directions. At this time, most of the prior art will increase the complexity of the mechanism and control logic by adding a drive device or resetting the control logic to meet the movement requirements. This brings greater production and maintenance costs to the device manufacturer. The present application realizes the Y-direction movement of the transmission assembly 4 by setting a chute in the vertical direction of the first connecting block 303, with a simple structure and reasonable design. Since there is movement in both the X and Y directions, the limit groove structure can be a curved structure, which is the same as the movement trajectory of the second connecting plate 402.

[0033] In a specific embodiment, the transmission assembly 4 further includes a third connecting plate 405, one side of the third connecting plate 405 has a first slider 406 arranged in a horizontal direction, the first slider 406 is adapted to the first slide rail 102 arranged on the housing 1, and the other side of the third connecting plate 405 has a second slider 407 arranged in a vertical direction, the second slider 407 is adapted to the second slide rail on the second connecting plate 402. By setting the third connecting plate 405 and setting the first slider 406 on one side of the third connecting plate 405, the third connecting plate 405 can be stably operated in the X direction through the cooperation of the first slider 406 and the first slide rail 102. Two second sliders 407 are set on the other side of the third connecting plate 405, and the second sliders 407 are used in cooperation with the second slide rail on the second connecting plate 402 to achieve the stable operation of the second connecting plate 402 in the Y direction. Due to the action of the slider and the slide rail, the second connecting plate 402 can also be stably operated in the X direction together with the third connecting plate 405. This structural setting enables the second connecting plate 402 and the first connecting plate 401 softly connected thereto to operate stably in both the X and Y directions, thereby ensuring the stability of the equipment and improving the accuracy of the rope cutting process. In addition, the structure is simple, maintenance is convenient, and the cost is low.

[0034] In a specific embodiment, the transmission body 301 is a belt, or a screw, or a rack. The transmission body is a screw structure, which is stable and reliable in operation and simple in structure. Or it is a belt structure, which can further reduce the product cost under the premise of meeting the transmission requirements. Of course, the transmission body 301 can also be other devices or structures that can play a transmission role.

[0035] Specifically, a support rod 302 is disposed on the side of the transmission body 301 , and two support rods 302 may be provided, which are disposed on opposite sides to improve the stability of the transmission process.

[0036] In a specific embodiment, the elastic member 403 is a spring or a rubber band. The spring or the rubber band can be used as an elastic member to form a soft connection between the first connecting plate 401 and the second connecting plate 402, and other structures that can achieve a soft connection or traction function can also be used. Preferably, the elastic member 403 is a spring.

[0037] In a specific embodiment, the stationary knife assembly 501 has a first knife body that cooperates with the movable knife assembly 502, and the cutting edge of the first knife body has a wire clamping groove 5011. The wire clamping groove 5011 is provided on the knife body to confine the rope in the wire clamping groove 5011, thereby effectively clamping the rope. When the movable knife moves toward the stationary knife, the rope will not shake, and the cutting effect is better.

[0038] In a specific embodiment, the stationary knife assembly 501 includes a knife support 5012, the first knife body is fixed on the knife support 5012, and the knife support 5012 is provided with a wire clamping groove 5011. The knife support 5012 is designed separately from the knife body, which is more cost-effective. Because the knife body is a consumable part, and the knife support is not easily damaged, if the knife body is damaged, the knife body can be replaced alone, which effectively reduces the cost.

[0039] In a specific embodiment, a guide slope is provided on one side of the opening of the clamping groove 5011 close to the first blade body. The guide slope is provided at the opening of the clamping groove 5011 to ensure that the rope slides smoothly into the clamping groove 5011, improve the rope cutting effect, and avoid missed cutting.

[0040] In a specific embodiment, the movable knife assembly 502 includes a second knife body, one end of which is rotatably connected to the stationary knife assembly 501, and the other end of which is connected to the first connecting plate 401 via a fourth connecting plate 5021. One end of the second knife body is rotatably connected to the stationary knife, so that the movable knife assembly 502 approaches the stationary knife assembly 501 to achieve rope cutting.

[0041] In a specific embodiment, the fourth connecting plate 5021 is connected to the first connecting plate 401 via a torsion spring 5023. Connecting the movable knife assembly 502 to the first connecting plate 401 via the torsion spring 5023 can improve the clamping force between the movable knife assembly 502 and the stationary knife assembly 501 and better cut the rope.

[0042] In a specific embodiment, the movable knife assembly 502 further includes a pressing plate 5022, one end of which is rotatably connected to the stationary knife assembly 501, and the other end of which is connected to the first connecting plate 401 through the fourth connecting plate 5021. The second knife body is located at the bottom of the pressing plate 5022 and moves together with the pressing plate 5022. The pressing plate 5022 structure is provided to cooperate with the knife support 5012 to achieve a clamping effect on the first knife body and the second knife body, and a better cutting effect.

[0043] In a specific embodiment, the first connecting plate 401 is provided with a third slider 4011, and the second connecting plate 402 is provided with a third slide rail 4021, and the third slider 4011 is adapted to the third slide rail 4021. The third slider 4011 is provided on the first connecting plate 401 to cooperate with the third slide rail 4021 on the second connecting plate 402, thereby improving the running stability of the first connecting plate 401.
