Description

Technical Field

[0001] The present invention belongs to the technical field of twisting equipment, and particularly relates to a twisting machine for continuous twisting of yarns, and more particularly to a conveying and twisting device for thick yarns and its usage method. Background Art

[0002] In the textile processing of thick yarns, the twisting and winding processes are the core links affecting the quality and production efficiency of the yarns.

[0003] In the related art, after the twisting is completed, a rigid yarn guide is usually used to guide the winding of the yarn. However, due to the characteristics of thick yarns, such as multiple strands and a fluffy structure, in the current environment where the winding speed tends to be increased, the frictional force is likely to increase significantly. Especially during long-term ultra-high-speed (winding speed > 800 m / min) continuous operation, the frictional heat between the yarn and the guiding components continuously accumulates, and the local temperature is extremely likely to exceed the softening point of the yarn, resulting in adhesion after melting on the surface of the yarn.

[0004] Therefore, how to avoid the surface melting and adhesion of thick yarns during guiding and conveying is a technical problem to be solved urgently at present.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

[0014] In an alternative embodiment, the number of the twisting components is multiple; The driving parts of the multiple twisting components are drivingly connected to the synchronous pulley of the motor through synchronous belts.

[0015] In a second aspect, an embodiment of the present disclosure further provides a method for using a conveying and twisting device for thick yarns as described above, and the method includes: Feeding the yarn into the twisting box through the wire guiding assembly; Twisting the yarn by the twisting component; Feeding the twisted thick yarn into the coiling and guiding assembly to coil and guide the thick yarn for subsequent coiling.

[0016] In an alternative embodiment, mounting holes are radially and outwardly formed in the inner wall of the guiding ring; The guiding wheel includes a protruding rod and a wheel body; One end of the protruding rod is elastically connected in the mounting hole through a return spring; The wheel body is rotatably arranged at the other end of the protruding rod; The supporting block includes: A block body; Two oppositely arranged brackets, which are arranged on the block body and form a rotating space for mounting the guiding ring; When coiling and guiding the thick yarn, the guiding wheel guides the thick yarn along the groove of the thick yarn, and at the same time, drives the guiding ring to rotate.

[0017] The beneficial effects of the present invention are that the conveying and twisting device for thick yarns and its using method of the present invention guide the thick yarn by inserting the guiding wheel into the yarn groove, convert the traditional large-area contact on one side into multi-side small-area surface contact, and at the same time, change from sliding friction to rolling friction, significantly reducing the friction contact area. Utilize the self-structural characteristics of the yarn to achieve dynamic stress dispersion, effectively inhibit the accumulation of frictional heat during high-speed coiling, and thus solve the problem of surface melting of thick yarns.

[0029] It has been found that when the thick yarn in the related art is wound up after being twisted, the surface of the thick yarn will show the phenomenon of yarn melting, and moreover, as the winding speed increases, the phenomenon of yarn melting becomes more serious.

[0030] Based on the above research, the embodiments of the present disclosure provide a conveying and twisting device for thick yarns and its working method. By inserting the guide wheel 430 into the yarn groove 510, the guiding mode of the thick yarn is changed, and the sliding friction is changed into rolling friction, effectively suppressing the accumulation of frictional heat during high-speed winding, thereby solving the problem of surface melting of the thick yarn.

[0031] Regarding the defects existing in the above solutions, they are all the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article for the above problems should all be the contributions made by the inventors to the present disclosure during the process of the present disclosure.

[0032] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] Please refer to Figure 1 and Figure 2, embodiments of the present disclosure provide a conveying and twisting device for thick yarns, including: a twisting box 100; a wire guiding assembly 200, which is arranged in the twisting box 100 and is used for guiding multiple yarns; a twisting assembly 300, which is arranged in the twisting box 100 and is used for twisting the multiple yarns led out by the guiding assembly; a winding and guiding assembly 400, which is arranged at the wire outlet end of the twisting box 100 and is used for winding and guiding the thick yarn 500 after twisting; wherein, the winding and guiding assembly 400 includes: a supporting block 410, which is arranged on the twisting box 100; a guiding ring 420, which is rotatably arranged on the supporting block 410, and the guiding ring 420 is provided with guiding wheels 430 along the radial direction inwards; when the winding and guiding assembly 400 winds and guides the thick yarn 500, the guiding wheels 430 of the guiding ring 420 are inserted into the groove 510 between adjacent two yarns, so as to reduce the heat generated when the thick yarn 500 is guided.

[0035] It should be noted that the twisting path of the thick yarn 500 is as Figure 1 shown by the dashed line in. The structural schematic diagram of the thick yarn 500 is as Figure 8 shown.

[0036] By embedding the guiding wheel 430 into the yarn groove 510 to guide the thick yarn, the traditional single-sided large-area contact is transformed into multi-sided small-area surface contact. At the same time, the static friction is changed into rolling friction, significantly reducing the friction contact area. Utilize the self-structural characteristics of the yarn 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 thick yarn.

[0037] Among them, the multi-sided small-area surface contact means that the contact surface between the winding and guiding assembly 400 and the yarn is divided by multiple guiding wheels 430, so that the heat generated by friction is dispersed to the entire side wall of the thick yarn, realizing dynamic stress dispersion, thereby dispersing the heat and reducing the accumulation of local heat, achieving the suppression of heat generation due to friction.

[0038] It should be noted that the small area is relative to the traditional single-sided large-area contact.

[0039] Please refer to Figure 2, an installation hole 421 is radially opened outward along the inner wall of the guide ring 420; 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 installation hole 421 through a return spring 433; the wheel body 432 is rotatably arranged at the other end of the protruding rod 431. When the winding and guiding assembly 400 winds and guides the thick yarn 500, the protruding rod 431 is pulled by the return spring 433 to drive the wheel body 432 to insert into the groove 510 between adjacent two strands of yarn. The guide wheel 430 is elastically connected to the guide ring 420 through the return spring 433, so as to adapt to the change of the yarn diameter of the thick yarn 500 for self-adaptive adjustment, thereby avoiding the phenomenon of jamming when the thick yarn 500 is wound, and further avoiding the surface temperature of the thick yarn 500 from being too high and reducing the accumulation of frictional heat on the surface of the thick yarn 500.

[0040] Please continue to refer to 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 rotating space for installing the guide ring 420; when winding and guiding the thick yarn 500, the guide wheel 430 guides the thick yarn 500 along the groove 510 of the thick yarn 500, and at the same time, drives the guide ring 420 to rotate.

[0041] Since the groove 510 on the surface of the thick yarn 500 is spiral, by setting the guide ring 420 to be rotatable to adapt to the spiral of the groove 510 and forming a double-rotation mode with the guide wheel 430, the friction between the guide wheel 430 and the groove 510 of the thick yarn 500 is further reduced, and thus the heat generated by the friction is reduced.

[0042] Specifically, since the groove 510 on the surface of the thick yarn is spiral, if the protruding rod 431 of the guide wheel 430 is fixed, when the thick yarn is pulled, the radial extrusion force between the groove 510 and the wheel body 432 of the guide wheel 430 will increase, resulting in an increase in the friction between the wheel body 432 of the guide wheel 430 and the groove 510. To avoid such a situation, in this embodiment, a rotatable guide ring 420 is set to compensate for the radial extrusion force, so that this part of the 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.

[0043] Please refer to Figure 3 and Figure 4The 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 the heat of the wheel body 432.

[0044] 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.

[0045] 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.

[0046] In a preferred embodiment, the number of guide wheels 430 is three, and the three guide wheels 430 are arranged in an equilateral triangle.

[0047] 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.

[0048] By replacing different winding guide assemblies 400 , the guiding requirements of coarse yarns 500 with different wire diameters can be met.

[0049] See also Figure 6 The twisting assembly 300 includes: a connecting pipe 310, which penetrates 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, so as to twist the coarse yarn 500.

[0050] 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 belt pulley.

[0051] The connecting tubes 310 of the plurality of twisting assemblies 300 are synchronously driven to rotate by the driving motor 340 to realize batch twisting.

[0052] Please refer to Figure 7 , at least one embodiment further provides a method of using a conveying and twisting device for thick yarns as described above, and the method includes: S110: Feed the yarn into the twisting box 100 through the wire guiding assembly 200; S120: Twist the yarn through the twisting assembly 300; S130: Feed the twisted thick yarn 500 into the winding and guiding assembly 400 to wind and guide the thick yarn 500 for subsequent winding.

[0053] In summary, the present invention provides a conveying and twisting device for thick yarns and a method of using the same. Among them, the conveying and twisting device for thick yarns includes: a twisting box 100; a wire guiding assembly 200, which is arranged in the twisting box 100 and is used for guiding multiple strands of yarns; a twisting assembly 300, which is arranged in the twisting box 100 and is used for twisting the multiple strands of yarns led out by the guiding assembly; a winding and guiding assembly 400, which is arranged at the wire outlet end of the twisting box 100 and is used for winding and guiding the twisted thick yarn 500; among them, the winding and guiding assembly 400 includes: a support block 410, which is arranged on the twisting box 100; a guiding ring 420, which is rotatably arranged on the support block 410, and the guiding ring 420 is provided with a guiding wheel 430 along the radial direction inward; when the winding and guiding assembly 400 winds and guides the thick yarn 500, insert the guiding wheel 430 of the guiding ring 420 into the groove 510 between adjacent two strands of yarns, so as to reduce the heat generated when the thick yarn 500 is guided. By inserting the guiding wheel 430 into the yarn groove 510 to guide the thick yarn 500, the traditional single-side large-area contact is transformed into multi-side small-area surface contact. At the same time, the sliding friction is changed into rolling friction, significantly reducing the friction contact area. Utilize the self-structural characteristics of the yarn 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 thick yarn 500.
