Description

Technical Field

[0001] The present invention belongs to the technical field of twisting equipment, and in particular relates to a twisting machine for continuous twisting of yarns, and more particularly to a conveying and twisting device for coarse yarns and a method for using the same. Background Art

[0002] In the textile processing of coarse yarn, twisting and winding processes are the core links that affect yarn quality and production efficiency.

[0003] After twisting, conventional conveying and twisting devices typically use rigid yarn guides to guide the yarn during winding. However, coarse yarns, due to their high strand count and bulky structure, can significantly increase friction in the current trend toward increasing winding speeds. Especially during long, ultra-high-speed (winding speeds > 800 m / min) continuous operation, frictional heat accumulates between the yarn and the guide components, and the local temperature can easily exceed the yarn's softening point, causing the yarn surface to melt and adhere.

[0004] Therefore, how to avoid surface melting and adhesion of coarse yarn during guidance and transportation is a technical problem that needs to be solved urgently.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0071] Research has found that when the coarse yarn in the related art is twisted and then wound up, the surface of the coarse yarn will melt, and the yarn melting phenomenon becomes more serious as the winding speed increases.

[0072] Based on the above research, an embodiment of the present disclosure provides a conveying and twisting device for coarse yarn and a working method thereof. By inserting the guide wheel 430 into the yarn groove 510, the guiding method of the coarse yarn is changed, and the sliding friction is converted into rolling friction, which effectively suppresses the accumulation of friction heat during high-speed winding, thereby solving the problem of surface melting of the coarse yarn.

[0073] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0074] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0075] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0076] See also Figure 1 and Figure 2 The embodiment of the present disclosure provides a coarse yarn conveying and twisting device, comprising: a twisting box 100; a conductor assembly 200, which is arranged in the twisting box 100 and is used to guide multiple strands of yarn; a twisting assembly 300, which is arranged in the twisting box 100 and is used to twist the multiple strands of yarn guided by the guide assembly; a winding guide assembly 400, which is arranged at the outlet end of the twisting box 100 and is used to wind and guide the twisted coarse yarn 500; wherein, The winding guide assembly 400 includes: a support block 410, which is arranged on the twisting box 100; a guide ring 420, which is rotatably arranged on the support block 410, and the guide ring 420 is provided with a guide wheel 430 radially inward; when the winding guide assembly 400 guides the coarse yarn 500 to be wound, the guide wheel 430 of the guide ring 420 is inserted into the groove 510 between two adjacent yarns, thereby reducing the heat generated by the coarse yarn 500 during guidance.

[0077] It should be noted that the twisting path of the coarse yarn 500 is as follows: Figure 1 As shown by the dotted line in FIG. The structural diagram of the coarse yarn 500 is shown in FIG. Figure 8 shown.

[0078] By embedding guide wheel 430 within yarn groove 510 to guide the coarse yarn, the traditional single-sided, large-area contact is transformed into multi-sided, smaller-area contact. At the same time, static friction is transformed into rolling friction, significantly reducing the frictional contact area. This utilizes the yarn's inherent structural characteristics to achieve dynamic stress dispersion, effectively suppressing frictional heat accumulation during high-speed winding, thereby resolving the problem of surface melting in coarse yarns.

[0079] Among them, multi-sided small-area surface contact means that the contact surface between the winding guide assembly 400 and the yarn is divided by multiple guide wheels 430, so that the heat generated by friction is dispersed to the entire side wall of the coarse yarn, realizing dynamic stress dispersion, thereby dispersing the heat, reducing local heat accumulation, and suppressing frictional heat generation.

[0080] It should be noted that the small area is relative to the traditional single-sided large area contact.

[0081] See also Figure 2 The inner wall of the guide ring 420 has a mounting hole 421 radially extending outward. The guide wheel 430 includes a protruding rod 431 and a wheel body 432. One end of the protruding rod 431 is elastically connected to the mounting hole 421 via a return spring 433. The wheel body 432 is rotatably mounted on the other end of the protruding rod 431. When the winding guide assembly 400 is winding and guiding the coarse yarn 500, the protruding rod 431, pulled by the return spring 433, drives the wheel body 432 into the groove 510 between two adjacent yarn strands. The guide wheel 430 is elastically connected to the guide ring 420 via the return spring 433, adaptively adjusting to changes in the diameter of the coarse yarn 500. This prevents the coarse yarn 500 from getting stuck during winding, thereby preventing excessive surface temperature and reducing frictional heat accumulation on the coarse yarn 500.

[0082] Please continue reading Figure 2 The support block 410 includes: a block body 411; two oppositely arranged brackets 412, which are arranged on the block body 411 and form a rotation space for installing the guide ring 420; when guiding the coarse yarn 500 to be wound, the guide wheel 430 guides the coarse yarn 500 along the groove 510 of the coarse yarn 500, and at the same time, drives the guide ring 420 to rotate.

[0083] Since the groove 510 on the surface of the coarse yarn 500 is spiral, the guide ring 420 is set to rotate, the spiral line of the groove 510 is adapted to form a double rotation with the guide wheel 430, thereby further reducing the friction between the guide wheel 430 and the groove 510 of the coarse yarn 500, thereby reducing the heat generated by the friction.

[0084] Specifically, because the groove 510 on the surface of the coarse yarn is spiral, if the extension rod 431 of the guide wheel 430 is fixed, when the coarse yarn is pulled, the radial extrusion force between the groove 510 and the wheel body 432 of the guide wheel 430 will increase, thereby increasing the friction between the wheel body 432 of the guide wheel 430 and the groove 510. To avoid this situation, the present embodiment provides a rotatable guide ring 420 to compensate for the radial extrusion force. This radial extrusion force drives the guide ring 420 to reduce the friction between the wheel body 432 of the guide wheel 430 and the groove 510 caused by the radial extrusion force.

[0085] See also Figure 3 and Figure 4 The support block 410 is provided with an air intake hole 413 adapted to the mounting hole 421; the air intake hole 413 is connected to an external air source; a through hole 431a is provided in the middle of the extension rod 431; when the guide ring 420 rotates until the mounting hole 421 is connected to the air intake hole 413, air is sucked into the mounting hole 421 to drive the extension rod 431 to move radially outward along the guide ring 420, while dissipating heat from the wheel body 432.

[0086] Specifically, if Figure 4 As shown, when the guide ring 420 rotates until the mounting hole 421 is connected to the air intake hole 413, the air source flows along Figure 4 Inhale in the direction indicated by F, driving the extension rod 431 along Figure 4 The middle F2 moves downward, thereby temporarily separating the guide wheel 430 from the groove 510 of the coarse yarn 500.

[0087] It should be noted that the number of the guide wheels 430 is the same as the number of yarn strands of the coarse yarn 500; when the winding guide assembly 400 guides the coarse yarn 500, the guide wheel 430 of each guide ring 420 is inserted into the groove 510 between the corresponding two adjacent yarn strands.

[0088] In a preferred embodiment, the number of guide wheels 430 is three, and the three guide wheels 430 are arranged in an equilateral triangle.

[0089] See also Figure 5 , the number of the winding guide assemblies 400 is multiple; the multiple winding guide assemblies 400 are installed on the outer wall of the twisting box 100 through the connecting rod 440; wherein, the connecting rod 440 is detachably connected to the twisting box 100.

[0090] By replacing different winding guide assemblies 400 , the guiding requirements of coarse yarns 500 with different diameters can be adapted.

[0091] See also Figure 6The twisting assembly 300 includes: a connecting pipe 310, which passes through the side wall of the twisting box 100 and is rotatably connected to the twisting box 100; a twisting needle 320, which is connected to the connecting pipe 310 through a support rod; and a driving part 330, which is used to drive the connecting pipe 310 to rotate, thereby driving the twisting needle 320 to rotate, thereby twisting the coarse yarn 500.

[0092] There are multiple twisting assemblies 300 ; the driving parts 330 of the multiple twisting assemblies 300 are connected to the synchronous wheel of the motor 340 through a synchronous pulley.

[0093] The connecting tubes 310 of the plurality of twisting assemblies 300 are synchronously driven to rotate by the driving motor 340 to achieve batch twisting.

[0094] See also Figure 7 At least one embodiment further provides a method for using the above-mentioned coarse yarn conveying and twisting device, the method comprising:

[0095] S110: Sending the yarn into the twisting box 100 through the conductor assembly 200;

[0096] S120: twisting the yarn through the twisting assembly 300;

[0097] S130: sending the twisted coarse yarn 500 into the winding guide assembly 400 to guide the coarse yarn 500 for subsequent winding.

[0098] In summary, the present invention provides a coarse yarn conveying and twisting device and a method for using the same, wherein the coarse yarn conveying and twisting device comprises: a twisting box 100; a guide wire assembly 200, which is arranged in the twisting box 100 and is used to guide multiple strands of yarn; a twisting assembly 300, which is arranged in the twisting box 100 and is used to twist the multiple strands of yarn guided by the guide assembly; a winding guide assembly 400, which is arranged at the outlet end of the twisting box 100 and is used to twist the coarse yarn 5 after twisting. 00 Winding guide; wherein the winding guide assembly 400 includes: a support block 410, which is arranged on the twisting box 100; a guide ring 420, which is rotatably arranged on the support block 410, and the guide ring 420 is provided with a guide wheel 430 radially inward; when the winding guide assembly 400 guides the coarse yarn 500, the guide wheel 430 of the guide ring 420 is inserted into the groove 510 between two adjacent yarns, thereby reducing the heat generated by the coarse yarn 500 during guidance. By inserting the guide wheel 430 into the yarn groove 510, the coarse yarn 500 is guided, and the traditional single-sided large-area contact is converted into multi-sided small-area surface contact. At the same time, sliding friction is converted into rolling friction, significantly reducing the friction contact area. The structural characteristics of the yarn itself are utilized to achieve dynamic stress dispersion, effectively suppressing the accumulation of frictional heat during high-speed winding, thereby solving the problem of surface melting of the coarse yarn 500.
