Abstract
Description
Technical Field
[0001] The invention relates to the field of textile technology, in particular to a twisting device. Background Art
[0002] The task of the spinning and winding process is to process the ring-spun bobbin yarn into a specified shape of bobbin yarn. The winding process involves the work of removing yarn defects, that is, cutting the yarn and then reconnecting the cut yarn ends together by twisting. The quality of the joint directly affects the quality of the yarn, as well as the feasibility of the weaving process and the characteristics of the fabric. The main indicators include the strength, thickness, length, and resilience (stretch yarn) of the joint.
[0003] The main splicing methods used by winders on the market today include air twisting, aerosol twisting, and twisting. The most reasonable splicing methods are used for different yarn varieties. With the continuous diversification of yarn varieties, the adaptability of splicers is also constantly challenged. For some single yarns containing special fibers, core-spun yarns with high resilience, etc., the splicing is difficult. For example, the high-count yarn made of lyocell fiber has low air-twisting strength; the spandex core-spun yarn containing multiple thick deniers has large resilience, and twisting is mostly used, but the splicing joint length is long, and the twisting mechanical friction loss is large; in addition, some core-spun yarn varieties with ordinary rebound, even if aerosol twisting is used, there are still empty joints or low knot strength caused by spandex rebound.

[0017] Compared with the prior art, the present invention has achieved the following technical effects:
[0018] The splicing device provided by the present invention adopts a first splicing channel and a second splicing channel with two partially overlapping longitudinal sections, and is matched with a V-groove block and a clamp arranged on the outer side of each. When the first yarn and the second yarn are spliced, their respective ends will be cut off by corresponding mechanical scissors, and the corresponding broken parts will be untwisted by the untwisting tube on the corresponding side, that is, the broken parts of the first yarn and the second yarn are both in the shape of fluffy fiber bundles. Then, taking the first yarn as an example, the part of the first yarn in the second splicing channel will be twisted by the second rotatory airflow, and the first yarn in the first The part in the splicing channel will produce two actions under the action of the first rotary airflow, namely, the twisting action of the first yarn located on one side in the second splicing channel will continue to be strengthened, and the first yarn part in the first splicing channel will produce an untwisting movement based on the fact that this side has been clamped and fixed by the first clamping mouth. Similarly, the actions of the second yarn in the first splicing channel and the second splicing channel are opposite, that is, the first yarn is twisting in the second splicing channel, and the second yarn is untwisting in the second splicing channel. At this time, under the action of the second rotary airflow, the loose fiber bundles of the first yarn are staggered. The first yarn is wrapped around the second yarn segment that is in an untwisted state, thereby forming an effect of interlacing the fiber bundles of the first yarn and the second yarn, thereby enhancing the twisting effect. Similarly, the first yarn and the second yarn form the same twisting effect in the first twisting channel. Based on the high resilience of the first yarn, it will shrink after being broken, and at this time, the part of the first yarn close to the breaking point is in the first V-shaped groove, and the first V-shaped groove is in a semi-gripping state for the position of the first yarn close to the breaking point, that is, a large area around the first yarn forms contact friction with the inner wall of the first V-shaped groove, thereby generating friction on the first yarn. A certain anti-retraction effect is provided at the yarn break point to ensure the length of the first yarn in the second twisting channel, thereby providing a guarantee for the twisting length of the first yarn and the second yarn, and the contact friction rotation action between the first V-groove and the first yarn and the second yarn can also produce a similar twisting effect on the twisting of the first yarn and the second yarn, resulting in a knot effect similar to twisting; combined together, an airflow twisting is formed at the overlapping position in the middle of the first yarn and the second yarn, and a twisting twisting effect is formed at the ends of the first yarn and the second yarn where they are broken, thereby improving the twisting effect on high-elastic yarns.
[0019] Furthermore, the first splicing channel, the first V-groove and the first clamping mouth are respectively arranged at a certain height level, which is conducive to the reasonable control of the tension of the yarn, and after the yarn end is disconnected, it can be better restricted by the corresponding first V-groove and second V-groove, thereby reducing the retraction of the yarn and improving the splicing effect.
[0020] Furthermore, the upper opening is provided to facilitate the first yarn and the second yarn to enter the first splicing channel and the second splicing channel of the splicer, and installation and use are simpler and more convenient; and the splicing effect of the first yarn and the second yarn can be intuitively observed.
[0021] Furthermore, the upper V-shaped groove facilitates the first yarn and the second yarn to enter the first splicing channel and the second splicing channel, and the vertical groove makes it easier to guide the first yarn and the second yarn into the space corresponding to the overlapping area of the longitudinal sections of the first splicing channel and the second splicing channel.
[0022] Furthermore, the connecting structure between the first airflow chamber and the first splicing channel and the connecting structure between the second airflow chamber and the second splicing channel are the same. This consistency makes the entire splicing device have similar working principles and modes in terms of airflow supply, simplifies the design and manufacturing process of the device, and can be based on unified standards and methods during equipment debugging, maintenance and daily operations, thereby reducing operational errors caused by structural differences and improving work efficiency; a dragging airflow layer and a pushing airflow layer are used in combination, wherein the dragging airflow layer can increase the gap between the yarn and the corresponding inner wall of the splicing channel, thereby increasing the rotation speed of the airflow rotating around the yarn, thereby increasing the twist of the yarn splicing position, making the thickness of the splicing section thinner, and enhancing the overall aesthetics of the yarn.
[0023] Furthermore, the conical expansion structure can play a buffering and regulating role. It allows the airflow to converge at the expansion before entering the second air flow hole, allowing the airflow to enter the second air flow hole more smoothly and evenly, and then enter the twisting channel, ensuring the formation of a stable rotary airflow in the twisting channel.
[0024] Furthermore, the structure of the cooperation between the V-groove and the yarn pressing claw can achieve precise positioning and clamping of the yarn. The yarn pressing claw tightly clamps the yarn by cooperating with the V-groove, effectively preventing the yarn from shifting or slipping during the clamping process, ensuring that the yarn can be accurately in the required position during the splicing operation, and improving the accuracy and quality of the splicing; the size change of the two clamping openings is controlled by the same connecting shaft rod, so it can be well ensured that the first clamping opening and the second clamping opening can maintain the same size change at any time, so that the clamping force on the two yarns when clamped is relatively uniform, avoiding the splicing quality affected by clamping one yarn too tightly or too loosely due to the difference in clamping force, thereby ensuring the consistency of the splicing process and the quality of the spliced product.
[0025] Furthermore, the rounded corners can effectively prevent the yarn from directly contacting the sharp groove edge, allowing the yarn to smoothly transition when entering the groove, greatly reducing the risk of yarn wear, ensuring the integrity of the yarn, and helping to improve the strength and appearance quality of the yarn after twisting.
[0026] Furthermore, the first V-shaped groove is symmetrically arranged with a first straight surface and a second straight surface, so that the bottom V-shaped angle formed is easier to form contact friction between the yarns; and the first yarn guide V-groove is composed of a first yarn guide arc surface and a second yarn guide arc surface, which can not only play a good guiding role for the yarn, but also avoid excessive extrusion of the two sides with the yarn to cause wear on the yarn.
[0027] Furthermore, the splicer consists of a splicing block and a splicing base. The splicing block is fixedly arranged in a U-shaped mounting groove of the splicing base. This embedded mounting method enables the splicing block to obtain stable support during operation, effectively avoiding displacement or shaking of the splicing block due to external vibration or other factors, thereby ensuring the stability of the splicing device during operation, which is crucial to maintaining the accuracy and consistency of the splicing operation; since the two air flow chambers have the same structure and are connected in the same way as the ventilation channels, when adjusting the airflow, the airflow in the two splicing channels can be synchronously and accurately regulated.

[0050] By adopting a first splicing channel 111 and a second splicing channel 112 with two partially overlapping longitudinal sections, and matching the V-groove blocks and clamps arranged on the outer sides of each, when the first yarn and the second yarn are spliced, their respective ends will be cut off by the corresponding mechanical scissors, and the corresponding broken parts will be untwisted by the untwisting tube on the corresponding side, that is, the broken parts of the first yarn and the second yarn are both in the shape of fluffy fiber bundles. Then, taking the first yarn as an example, the part of the first yarn in the second splicing channel 112 will be twisted by the second rotatory airflow, and the first yarn in the first splicing channel 111 will be twisted. The part of the yarn will produce two actions under the action of the first rotatory airflow, namely, the twisting action of the first yarn on one side in the second splicing channel 112 is continued to be strengthened, and the first yarn part in the first splicing channel 111, based on the fact that the side is clamped and fixed by the first clamping mouth, produces an untwisting action. Similarly, the actions of the second yarn in the first splicing channel 111 and the second splicing channel 112 are opposite, namely, the first yarn is twisted in the second splicing channel 112, and the second yarn is untwisted in the second splicing channel 112. At this time, under the action of the second rotatory airflow, the first yarn is loosened. The scattered fiber bundles are interlaced and wrapped around the second yarn segment that is in an untwisted state, forming an effect of interlacing the fiber bundles of the first yarn and the second yarn, thereby enhancing the twisting effect. Similarly, the first yarn and the second yarn form the same twisting effect in the first twisting channel 111. Based on the high resilience of the first yarn, it will shrink after breaking, and at this time, the part of the first yarn close to the breaking point is in the first V-shaped groove, and the first V-shaped groove is in a semi-gripping state for the position of the first yarn close to the breaking point, that is, a large area around the first yarn forms contact friction with the inner wall of the first V-shaped groove, thereby A certain anti-retraction effect is produced on the disconnection point of the first yarn to ensure the length of the first yarn in the second twisting channel 112, and provide a guarantee for the twisting length of the first yarn and the second yarn. In addition, the contact friction rotation action between the first V-groove and the first yarn and the second yarn can also produce a similar twisting effect on the twisting of the first yarn and the second yarn, and a knotting effect similar to twisting occurs. Combined together, the first yarn and the second yarn are twisted at the overlapping position in the middle, and the first yarn and the second yarn are twisted at the ends of the disconnection point, thereby improving the twisting effect on the high-elastic yarn.

[0063] In the optional scheme of this embodiment, it is more preferred that Figure 1 to Figure 3 As shown, the first clamper 40 includes a first yarn guide plate 41 and a first yarn pressing claw 42; the second clamper 50 includes a second yarn guide plate 51 and a second yarn pressing claw 52; the first yarn guide plate 41 is provided with a first yarn guide V-groove, the first yarn pressing claw 42 is located at the opening of the first yarn guide V-groove, and the first yarn pressing claw 42 and the first yarn guide V-groove together form a first clamping opening; the second yarn guide plate 51 is provided with a second yarn guide V-groove, the second yarn pressing claw 52 is located at the opening of the second yarn guide V-groove, and the second yarn pressing claw 52 and the second yarn guide V-groove together form a second clamping opening; the first yarn pressing claw 42 is fixedly connected to a connecting shaft rod, and the second yarn pressing claw 52 is fixedly connected to the connecting shaft rod; the connecting shaft rod can drive the first yarn pressing claw 42 and the second yarn pressing claw 52 to rotate around the axis of the connecting shaft rod and correspondingly complete the changes in the sizes of the first clamping opening and the second clamping opening. The structure of the V-groove and the yarn pressing claw can achieve precise positioning and clamping of the yarn. The yarn pressing claw clamps the yarn tightly by cooperating with the V-groove, effectively preventing the yarn from shifting or slipping during the clamping process, ensuring that the yarn is accurately in the required position during the splicing operation, and improving the accuracy and quality of the splicing. The size changes of the two clamping openings are controlled by the same connecting shaft, so it can be well ensured that the first clamping opening and the second clamping opening can maintain the same size change at any time, so that the clamping force on the two yarns when clamped is relatively uniform, avoiding the splicing quality affected by one yarn being clamped too tightly or too loosely due to the difference in clamping force, thereby ensuring the consistency of the splicing process and the quality of the spliced product.
[0064] Among them, about other related settings description:
[0065] In the optional scheme of this embodiment, it is more preferred that Figure 1 to Figure 3As shown, in the vertical direction, the heights of the first V-shaped groove and the second V-shaped groove are consistent, and the heights of the first clamping opening and the second clamping opening are consistent; the axis heights of the first splicing channel 111 and the second splicing channel 112 are higher than the height of the first V-shaped groove, and the height of the first V-shaped groove is higher than the height of the first clamping opening. The first splicing channel 111, the first V-shaped groove and the first clamping opening are respectively arranged in a certain height level, which is conducive to the reasonable control of the tension of the yarn, and after the yarn end is disconnected, it can be better restricted by the corresponding first V-shaped groove and second V-shaped groove, reducing the retraction of the yarn and improving the splicing effect.
[0066] In the optional scheme of this embodiment, it is more preferred that Figure 1 to Figure 4 As shown, the first V-shaped groove includes a first straight surface and a second straight surface that are symmetrically arranged; the lower end of the first straight surface is connected to the lower end of the second straight surface; the first yarn guide V-groove includes a first yarn guide arcuate surface and a second yarn guide arcuate surface that are symmetrically arranged; the lower end of the first yarn guide arcuate surface is connected to the lower end of the second yarn guide arcuate surface. The first V-shaped groove adopts the first straight surface and the second straight surface to be symmetrically arranged, so that the bottom V-shaped angle formed is easier to form contact friction between the yarns; and the first yarn guide V-groove is composed of the first yarn guide arcuate surface and the second yarn guide arcuate surface, which can play a good guiding role on the yarn and can also avoid excessive extrusion of the two sides with the yarn to cause wear on the yarn.
[0067] Specifically, the splicer 10 is integrally assembled and fixed on the compressed air outlet of the splicing base 60, and the compressed air outlet is communicated with the ventilation channel.
[0068] Specifically, when the external manipulator introduces the yarn, it is introduced into the corresponding twisting channel through the yarn guide plate. At this time, the yarn pressing claw is pressed down to hold the yarn at the yarn guide plate; the two yarn tail ends are cut off by the mechanical scissors on both sides and pulled back by the stretching device. For highly elastic yarn, it will produce a large retraction along its own axial direction. At this time, if there is no V-groove block, the retracted yarn end is easy to escape from the control of the yarn guide plate and the yarn pressing claw, causing the yarn tail ends on both sides to retract and escape from overlapping, eventually resulting in an empty twist.
[0069] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
