[0001] The present application relates to the technical field of yarn cutting device, in particular to a self-adaptive cutting device for yarn with super-thick fineness and yarn production equipment. BACKGROUND

[0002] In the prior art, yarn cutting mainly adopts two methods of blade translation cutting and hot-melt of heat-conducting metal wire. The device using blade translation cutting has a blade installed at the end of a cylinder, which moves with the cylinder shaft. A pair of clamping plates are installed for clamping the yarn. One clamping plate is fixed on the cylinder, and the other clamping plate is fixed on the outer cover. There is a hollow in the middle of the clamping plate for facilitating the movement of the blade. When working, the cylinder in the cutter box pushes the fixed blade to cut the yarn clamped by the clamping plate. However, when the fineness of the yarn is too large (≥20000D) or the blade is blunt, the yarn cutting failure rate is significantly increased. The device using hot-melt of heat-conducting metal wire heats the metal wire by electricity to burn the yarn. However, it has the safety hazard of open flame, and produces smoke and peculiar smell. If discharged outdoors, it is easy to cause environmental pollution. SUMMARY

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and defined, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1 , Figure 2 As shown, this embodiment provides an adaptive cutting device for coarse-grained yarns, including: a cutter box 1, for example, the cutter box 1 can be a cuboid box, and the cutter box 1 is provided with a yarn groove 101, for example, the yarn groove 101 can be a groove that extends inward from one side of the cutter box 1 along its length and is consistent with the width direction of the cutter box 1; a hook member 2, the hook member 2 including a hook end 201 and a connecting end 202, the connecting end 202 of the hook member 2 is hinged to the cutter box 1 so that the hook member 2 and the cutter box 1 can rotate toward each other and the hook end 201 feeds the yarn 15 into the yarn groove 101; a disc blade 3, which is rotatably disposed in the cutter box 1, and the edge of the disc blade 3 contacts the yarn 15 located in the yarn groove 101, and can cut the yarn 15 when the disc blade 3 rotates.

[0023] The adaptive cutting device for ultra-coarse yarn provided in this embodiment involves the cutter box 1 and the hook 2 rotating towards each other during use. The hook end 201 feeds the yarn 15 into the yarn groove 101. Then, the disc blade 3 rotates to cut the yarn 15. This configuration, compared to devices that use blade translation for cutting, can still cut the yarn 15 even when it is too coarse or the blade is dull. Moreover, compared to devices that use heat-conducting metal wire for hot melting, it avoids the safety hazard of open flame and also avoids environmental pollution caused by smoke and odors generated during the cutting process.

[0024] The ultra-coarse yarn adaptive cutting device also includes a yarn clamping mechanism 4, which is set inside the cutter box 1. The yarn clamping mechanism 4 is used to clamp the yarn 15 fed into the yarn groove 101. This setting can prevent the yarn 15 from moving back and forth when the disc blade 3 cuts the yarn 15, thus affecting the cutting effect.

[0025] The wire clamping mechanism 4 includes a wire clamping block 401, a clamping cylinder 402, and a wire clamping plate 403. The wire clamping block 401 is fixedly connected to the inner wall of the cutter box 1. For example, the wire clamping block 401 can be glued or fixed to the inner wall of the cutter box 1 by bolts. For example, in order to prevent interference when cutting the yarn 15, a blade clearance groove 4011 can be provided on the side of the wire clamping block 401 facing the wire clamping plate 403. The blade clearance groove 4011 can be a strip-shaped gap with a width greater than the thickness of the disc blade 3. The connecting part of the clamping cylinder 402 is connected to the inner wall of the cutter box 1. For example, the connecting part of the clamping cylinder 402 can be fixed to the inner wall of the cutter box 1 by bolts. The actuating part of the clamping cylinder 402 is connected to the wire clamping plate 403. For example, the actuating part of the clamping cylinder 402 can be connected to the wire clamping plate 403 by bolts. The clamping cylinder 402 is used to drive the wire clamping plate 403 to move toward the wire clamping block 401 to clamp the yarn 15. After the hook member 2 presses the yarn 15 into the yarn groove 101, the clamping cylinder 402 can drive the wire clamping plate 403 to move toward the wire clamping block 401 until the yarn 15 is clamped by the wire clamping block 401 and the wire clamping plate 403, after which the yarn 15 can be cut. With this setup, combined with the downward pressure of the hook 2 on the yarn 15, the yarn 15 can be straightened and prevented from moving, making it easier to cut the yarn 15.

[0026] The clamping plate 403 comprises two parallel, spaced-apart plates, with the disc blade 3 positioned between them. For example, the two parallel, spaced-apart plates of the clamping plate 403 can be separate plates or a single unit. For instance, the clamping plate 403 can be U-shaped, with the U-shaped opening facing the clamping block 401; alternatively, the clamping plate 403 can be a block structure with a groove on the side facing the clamping block 401, where the disc blade 3 is located, and the width of the groove is greater than the thickness of the disc blade 3. For example, mounting holes can be provided on the clamping plate 403, allowing the disc blade 3 to be rotatably mounted between the two plates of the clamping block 401 using a shaft and bearings. The spacing between the two plates of the clamping plate 403 aligns with the blade clearance groove 4011 on the clamping block 401, ensuring that the clamped yarn 15 is perpendicular to the plane containing the disc blade 3 during cutting.

[0027] The adaptive cutting device for coarse yarn also includes a drive motor 5 and a belt 6. The connection part of the drive motor 5 is connected to the clamping plate 403, and the actuating part of the drive motor 5 is connected to the rotating shaft of the disc blade 3 via the belt 6 to drive the disc blade 3 to rotate. For example, the housing of the drive motor 5 can be located outside the cutter box 1, the actuating part of the drive motor 5 is the output shaft, and the belt 6 is wound between the output shaft of the drive motor 5 and the rotating shaft of the disc blade 3. When the yarn 15 is clamped, the drive motor 5 rotates and transmits power through the belt 6 to drive the disc blade 3 to rotate.

[0028] The adaptive cutting device for coarse-fiber yarns includes a push plate 7, a support rod 8, a pressure block 9, and an elastic element 10. The push plate 7 is connected to the actuating part of the clamping cylinder 402, which is a telescopic head. For example, the push plate 7 can be bolted to the telescopic head of the clamping cylinder 402, and a through hole can be provided on the push plate 7. One end of the support rod 8 passes through the through hole on the push plate 7, and the other end can be fixedly connected to the clamping plate 403. The pressure block 9 is slidably mounted on the support rod 8. For example, the elastic element 10 can be a helical spring, which is sleeved on the support rod 8 and located on the side of the pressure block 9 away from the push plate 7. When it is necessary to clamp the yarn 15, the actuating part of the clamping cylinder 402 drives the push plate 7 to slide along the support rod 8 and drives the pressure block 9 to move after the push plate 7 contacts the pressure block 9. During the sliding process of the pressure block 9 along the support rod 8, the elastic element 10 is continuously compressed and the elastic element 10 is used to push the clamping plate 403 to move. For example, two support rods 8 can be set at an interval, one above the other, to better guide the movement and improve the accuracy of linear motion. This arrangement can act as a buffer, ensuring that the clamping plate 403 has a certain clamping effect on the yarn 15, while also allowing the reverse thrust of the yarn 15 on the disc blade 3 to be adjustable.

[0029] Both the clamping block 401 and the clamping plate 403 have inclined guide surfaces near the entrance of the yarn groove 101 to form a V-shaped guide inlet 11 at the entrance of the yarn groove 101. This arrangement makes it easier for the hook member 2 to feed the yarn 15 into the yarn groove 101, thereby increasing the success rate of cutting the yarn 15.

[0030] On the other hand, the present invention also provides a yarn production apparatus, including the ultra-coarse fineness yarn adaptive cutting device of any one of the above.

[0031] The yarn production equipment also includes a frame, a swing cylinder 12, a swing shaft 13, and a connecting rod 14. The connecting part of the swing cylinder 12 is connected to the frame, and the actuating part of the swing cylinder 12 is connected to the cutter box 1 via the swing shaft 13. For example, the actuating part of the swing cylinder 12 is a telescopic head. One end of the telescopic head connected to the swing shaft 13 can be hinged with an irregularly shaped connecting plate. The connecting plate can be fixedly connected to the end of the swing shaft 13 away from the cutter box 1. The irregularly shaped connecting plate can convert the linear motion of the telescopic head into a torque applied to the swing shaft 13 in a clockwise or counterclockwise direction. The end of the swing shaft 13 near the cutter box 1 can be fixedly connected to a connecting seat. The connecting seat can be connected to the cutter box 1 via bolts. The cutter box 1 and the yarn trough 10 The position 1 is diagonally connected to the frame via a hinge support. The swing cylinder 12 drives the cutter box 1 to rotate relative to the frame via the swing shaft 13. For example, when the telescopic head of the swing cylinder 12 retracts, a clockwise torque can be applied to the swing shaft 13 via the irregularly shaped connecting plate. The swing shaft 13 transmits the torque to the cutter box 1 via the connecting seat, and the cutter box 1 swings clockwise relative to the frame. One end of the connecting rod 14 is hinged to the hook piece 2, and the other end is hinged to the frame. The swing cylinder 12 drives the cutter box 1 to rotate via the swing shaft 13, so that the yarn groove 101 moves toward the hook end 201, and drives the hook piece 2 to rotate under the action of the connecting rod 14, so that the hook end 201 moves toward the yarn groove 101. For example, the hook element 2 can be U-shaped with two parallel rods. The cutter box 1 is located at least partially between the two rods of the hook element 2 from its opening. The end of the hook element 2 furthest from the opening is the hook end 201, which has a hook for hooking the line. The end of the hook element 2 closest to the opening serves as the connecting end 202, which is rotatably connected to the cutter box 1. With this configuration, the swing shaft 13 and the cutter box 1 are inclined to optimize the trajectory of the hook element 2 into a cycloidal motion, increasing the success rate of yarn 15 capture to 100%.

[0032] In use, the swing cylinder 12 pushes the swing shaft 13 to rotate 30°, and the connecting rod 14 on the cutter box 1 drives the hook 2 to rotate, hooking the yarn 15 into the yarn groove 101 of the cutter box 1; then, the clamping cylinder 402 pushes the clamping plate 403 to move, and the wedge-shaped tooth surface engages with the clamping block 401. The compression of the spiral spring can be Δx=15mm, and the clamping force can be F=30N; then, the drive motor 5 can drive the disc blade 3 at n=6000r / min, and the yarn 15 can be cut within 3ms.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to cover all possible implementations. Those skilled in the art will recognize that various variations and modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations and modifications derived therefrom are still within the scope of protection of this invention.
