Description

Technical Field

[0001] This application relates to the field of textile machinery technology, and in particular to a fringe knotting mechanism and its application in a scarf twisting and knotting machine. Background Technology

[0002] In the scarf manufacturing industry, to enhance the decorative appeal and structural stability of scarves, the tassels (also known as fringes) at the edges of the scarf are typically twisted and knotted. This process is one of the key steps in the finished scarf manufacturing process. With the development of automated production technology, the industry has widely adopted scarf tassel twisting and knotting devices to replace traditional manual twisting and knotting, thereby improving production efficiency and ensuring the consistency of twisting and knotting quality.

[0003] In existing scarf fringe twisting and knotting devices, the knotting mechanism is one of the core components. It generally consists of a knotting clamp and a clamping hook, which work together through a pre-set mechanical linkage to complete the knotting action of the fringe. In the knotting process, the knotting clamp and the clamping hook perform a clamping step on the fringe rope end. Specifically, the lower end face of the hook of the clamping hook and the upper end face of the hook of the knotting clamp form a relative clamping surface, and the fringe rope end is clamped and fixed by the clamping hook approaching the knotting clamp.

[0004] However, the existing clamping methods have significant drawbacks: the existing knotting clips and clamping hooks often experience the tassel ends coming loose, preventing the knotting action from completing along the preset trajectory and causing knotting failure. This problem not only reduces the pass rate of scarf production and affects product quality, but also requires additional manpower and time to repair or rework defective products, significantly increasing production costs, restricting the operating efficiency of automated production lines, and failing to meet the demand for large-scale, high-quality scarf production. Utility Model Content

[0005] Therefore, it is necessary to provide a tassel knotting mechanism to enhance the clamping effect on the tassel rope end and reduce the probability of the rope end coming off the hook.

[0006] This application provides a fringe knotting mechanism, including a knotting clip and a clamping hook that are slidably disposed relative to each other. The knotting clip is provided with a first hook portion and the clamping hook is provided with a second hook portion. The first hook portion and the second hook portion are arranged opposite to each other along a first direction, and a clamping groove can be formed between the first hook portion and the second hook portion. The clamping groove has a clamping position for clamping the fringe rope end and a releasing position for releasing the fringe rope end. The groove surface of the clamping groove is provided with a groove for accommodating part of the fringe rope end.

[0007] The first hook and the second hook are arranged to move along a first direction to approach each other so that the clamping groove is in a clamping position, or to move away from each other so that the clamping groove is in a releasing position.

[0008] In one embodiment, a groove is provided on the first hook portion, and along the projection of the first direction, the edge of the projection range of the groove is located outside the edge of the projection range of the second hook portion.

[0009] In one embodiment, the width direction of the first hook portion along the perpendicular first direction is defined as the second direction, and the groove passes through the first hook portion along the second direction.

[0010] In one embodiment, the knotting clip includes a first hook body fixedly connected to a first hook portion, and the clamping hook includes a second hook body fixedly connected to a second hook portion. The first hook body and the second hook body are inner and outer sleeved together and can slide relative to each other along a first direction.

[0011] In one embodiment, a groove is provided through the first hook body extending along a first direction, and at least a portion of the second hook body is located within the groove.

[0012] In one embodiment, when the clamping hook and the knotting clip slide relative to each other along the first direction, the side of the second hook body away from the second hook portion is always located on the side of the first hook body away from the first hook portion.

[0013] In one embodiment, the outer periphery of the first hook body is fitted with a driven gear for receiving power transmission and driving the first hook body to rotate, and the second hook body is circumferentially limited to the first hook body, with the axis of the driven gear extending in the same direction as the first direction.

[0014] In one embodiment, along a first direction, the cross-section of the first hook body at the connection between the first hook body and the first hook portion is larger than the cross-section of the first hook portion.

[0015] In one embodiment, an elastic element is also included, which causes the first hook and the second hook to always tend to move closer to each other along a first direction to a clamping position.

[0016] On the other hand, this application also provides a scarf twisting and knotting machine, including the tassel knotting mechanism described above.

[0017] Compared with the prior art, the wick knotting mechanism provided in this application provides a groove on the groove surface of the clamping groove formed by the first hook and the second hook, so that the wick rope end can bend and deform into the groove when it is clamped by the first hook and the second hook, thereby enhancing the clamping effect of the first hook and the second hook on the rope end, effectively reducing the occurrence of wick rope end falling off, ensuring the quality of wick rope end knotting production and processing, and reducing subsequent repair and rework costs.

[0031] Please see Figures 1 to 5This application provides a fringe knotting mechanism, including a knotting clip 200 and a clamping hook 100 that are slidably disposed relative to each other. The knotting clip 200 is provided with a first hook portion 201, and the clamping hook 100 is provided with a second hook portion 101. Figure 2 , Figure 3 As shown, the first hook portion 201 and the second hook portion 101 are arranged opposite each other along the first direction X, and a clamping groove 300 can be formed between the first hook portion 201 and the second hook portion 101. The clamping groove 300 has a clamping position for clamping the end of the tassel rope and a releasing position for releasing the end of the tassel rope. The groove surface of the clamping groove 300 is provided with a groove 204 for accommodating part of the end of the tassel rope. The first hook portion 201 and the second hook portion 101 are arranged so that they can move closer to each other along the first direction X so that the clamping groove 300 is in the clamping position, or move further away from each other so that the clamping groove 300 is in the releasing position.

[0032] See Figure 5 With this configuration, when the fringe end needs to be clamped, it must be located in the clamping groove 300 between the first hook 201 and the second hook 101. The fringe knotting mechanism, through the relative sliding of the knotting clamp 200 and the clamping hook 100, causes the first hook 201 and the second hook 101 to move closer together along the first direction X and compress the fringe end. During the compression deformation process, part of the fringe end deforms and enters the groove 204, enhancing the clamping effect of the first hook 201 and the second hook 101 on the fringe end and effectively reducing the possibility of the fringe end falling off during the knotting process. Conversely, after the fringe end is knotted, the relative sliding of the knotting clamp 200 and the clamping hook 100 along the first direction X causes the first hook 201 and the second hook 101 to move away from each other, putting the clamping groove 300 in a loosened position and releasing the clamping effect on the fringe end. At this point, the fringe end can detach from the fringe knotting mechanism.

[0033] See Figure 2 and Figure 5 In this embodiment, the groove 204 is formed on the first hook portion 201. During the clamping process, the end of the tassel rope will deform towards the side of the first hook portion 201 where the groove 204 is formed. It can be understood that the groove 204 can also be formed on the second hook portion 101, or both the first hook portion 201 and the second hook portion 101 have grooves 204, so that the end of the tassel rope can deform into the groove 204 after being squeezed, so as to enhance the clamping effect and the anti-loosening effect.

[0034] In some preferred embodiments, the groove 204 is disposed on the first hook portion 201, and along the projection of the first direction X, the edge of the projection range of the groove 204 is located outside the edge of the projection range of the second hook portion 101. See also Figures 2 to 5In this embodiment, the dimensions of the groove 204 and the second hook 101 are limited to a certain extent, so that when the second hook 101 and the first hook 201 approach each other along the first direction X to squeeze the end of the tassel rope, the end of the tassel rope can be deformed more obviously into the groove 204, thereby further enhancing the clamping effect and the anti-loosening effect.

[0035] Additionally, see Figure 4 The groove 204 and the second hook 101 are designed in this way so that when the fringe rope end does not need to be clamped, part or even all of the second hook 101 can be stored in the groove 204, reducing the space occupied by the fringe knotting mechanism in the idle or non-working state.

[0036] In a further preferred embodiment, see Figures 2 to 4 The width direction of the first hook portion 201 perpendicular to the first direction X is defined as the second direction Y. Along the second direction Y, the groove 204 penetrates the first hook portion 201. On the one hand, this allows the second hook portion 101 to be completely retracted into the groove 204, reducing interference with the second hook portion 101; on the other hand, the through groove 204 facilitates the molding and manufacturing of the knotting clip 200 and saves on the production materials of the knotting clip 200.

[0037] In some embodiments of this application, participants Figure 1 and Figure 2 The knot clamp 200 includes a first hook body 202 fixedly connected to the first hook portion 201, and the clamping hook 100 includes a second hook body 102 fixedly connected to the second hook portion 101. The first hook body 202 and the second hook body 102 are inner and outer together and can slide relative to each other along a first direction X. Specifically, the first hook body 202 and the knot clamp 200 can be integrally formed, and similarly, the second hook body 102 and the clamping hook 100 can also be integrally formed, eliminating the need for other forms of fixed connection between the knot clamp 200 and the first hook body 202, as well as the clamping hook 100 and the second hook body 102, making the manufacturing process of the entire knot clamp 200 and clamping hook 100 simpler and more convenient. In addition, the inner and outer arrangement of the first hook body 202 and the second hook body 102 provides a guiding effect for the relative sliding between the knot clamp 200 and the clamping hook 100, making the relative sliding between the knot clamp 200 and the clamping hook 100 more stable.

[0038] In other embodiments (not shown), a groove 203 extending along the first direction X can be formed on the second hook body 102, with the first hook body 202 located within the groove 203. More preferably, in this embodiment, a groove 203 is formed through the first hook body 202 extending along the first direction X, with at least a portion of the second hook body 102 located within the groove 203, and the second hook body 102 circumferentially limited to the first hook body 202. There are various ways to achieve circumferential limitation between the second hook body 102 and the first hook body 202. Generally, the groove 203 and the second hook body 102 can be in a non-circular fit. Specifically, the cross-section of the groove 203 is non-circular, and the portion of the second hook body 102 that fits with the groove 203 is also non-circular. See also Figure 1 In this embodiment, the cross-section of the groove 203 and the cross-section of the mating part of the second hook body 102 are adapted rectangular cross-sections. In this way, the first hook body 202 and the second hook body 102 avoid relative rotation in the relative sliding configuration, thereby improving the relative sliding stability.

[0039] Additionally, see Figures 2 to 4 As the clamping hook 100 and the knotting clip 200 slide relative to each other along the first direction X, the side of the second hook body 102 away from the second hook portion 101 is always located on the side of the first hook body 202 away from the first hook portion 201. It is understood that the length of the second hook body 102 must be longer than the first hook body 202. Figures 2 to 4 The clamping hook 100 slides downwards relative to the knotting clip 200 along the first direction X, and during this process, the lower end of the second hook body 102 always protrudes from the lower end of the first hook body 202.

[0040] Specifically, during the operation of this wicker knotting mechanism, the clamping hook 100 needs to slide relative to the knotting clamp 200 as an active sliding component, thereby realizing the relative sliding between the first hook portion 201 and the second hook portion 101. Therefore, when the clamping hook 100 and the knotting clamp 200 slide relative to each other, the lower end of the second hook body 102 always protrudes from the lower end of the first hook body 202, so that the second hook body 102 can receive the power used to drive the second hook body 102 to slide relative to the first hook body 202, thereby enabling the second hook body 102 to actively slide relative to the first hook body 202, so as to realize that the clamping hook 100 slides relative to the knotting clamp 200 along the first direction X.

[0041] In some embodiments of this application, the outer periphery of the first hook body 202 is fitted with a driven gear 400 for receiving power transmission and driving the first hook body 202 to rotate. The axis of the driven gear 400 extends in the same direction as the first direction X. Specifically, after receiving external power, the driven gear 400 rotates around its own axis, thereby driving the first hook body 202 and the entire knot clamp 200 to rotate. At the same time, since the first hook body 202 of the knot clamp 200 and the second hook body 102 of the clamping hook 100 slide relative to each other in the first direction and are engaged in an axial upper limit engagement, the knot clamp 200 will also drive the clamping hook 100 to rotate, so that the knot clamp 200 and the clamping hook 100 can also maintain the clamping effect on the end of the tassel during rotation.

[0042] In some embodiments of this application, along the first direction X, the cross-section of the first hook body 202 at the connection point between the first hook body 202 and the first hook portion 201 is larger than the cross-section of the first hook portion 201. See also Figures 2 to 4 This design prevents the knotted tassels from sliding down the first hook 202, thus avoiding difficulties in detaching the knotted tassels from the knotting clip 200 after subsequent knotting.

[0043] In some embodiments of this application, the wicking mechanism further includes an elastic element 500, which causes the first hook portion 201 and the second hook portion 101 to always tend to move closer to each other along the first direction X to a clamping position. It is understood that the elastic element 500 can be any component with elastic force, such as a spring, a gas spring, or a gasket.

[0044] See Figures 1 to 4 In some preferred embodiments, the elastic element 500 is a compression spring, with its two ends fixed to the first hook body 202 and the second hook body 102 respectively. During the relative sliding process of the knot clamp 200 and the clamping hook 100, the compression spring always has the tendency to drive the clamping hook 100 to move downward, that is, the compression spring always has the function of driving the second hook part 101 to move downward and closer to the first hook part 201.

[0045] Secondly, this application also provides a scarf twisting and knotting machine, including a fringe knotting mechanism as described in any of the above embodiments, to improve the clamping effect on the fringe rope end, enhance the anti-detachment performance, ensure the quality of the fringe rope end knotting production and processing, and reduce subsequent repair and rework costs.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
