[0002] In a covered yarn winding device, the winding process of the covered yarn usually involves frequent wire connection operations.

[0003] The devices for guiding and switching the covered yarn in the related art have the following defects: When the wire connection is completed and the two yarns are switched to the same wire groove for conveying, due to single-point splicing at the joint and the non-concentric misalignment arrangement of the two yarns, the joint area is prone to break under the action of shear force during the winding process. Especially in the high-speed winding scenario, the wire groove structure of the traditional device cannot achieve synchronous phase adjustment of the two yarns, and the misalignment and movement trajectory deviation at the joint form interference, causing the joint area to repeatedly bear non-uniform mechanical loads, resulting in an increased probability of wire breakage.

[0004] Therefore, how to solve the problem that the connection at the wire joint is prone to break during the winding of the covered yarn 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

[0029] It has been found through research that in the covering yarn winding equipment of the prior art, when covering yarn is being connected, due to manual misoperation, there is a deviation in the wire diameter at the joint after the two strands of covering yarn are connected, and when switching to the same wire groove for conveying, the joint area is prone to breakage under the action of shear force during the dynamic winding process. At the same time, with the single-point connection method, no matter which strand becomes loose near the connection point, the connection point will be disconnected.

[0030] Based on the above research, embodiments of the present disclosure provide a covering yarn winding equipment and its winding method. By placing the splicing ends of two strands of covering yarn at both ends of two wire grooves, after splicing, the two wire grooves are connected, so that the joint area changes from the traditional single-point force to the full-circumference support of the inner wall of the wire groove, effectively dispersing the shear force during the dynamic winding process. At the same time, the two knotting points are used for wiring. When one of the wiring points becomes loose and falls off, the other knotting point can ensure the firmness of the knotting place, reducing the risk of wire breakage.

[0031] All the defects existing in the above solutions are 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 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 represent 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, at least one embodiment provides a covered yarn winding device, including: a winding body 100, whose winding assembly is used to wind the covered yarn 300; a guiding assembly 200, which is used to guide the winding of the covered yarn 300.

[0035] The winding body 100 includes: a frame side plate 110; a winding assembly 120, which is used to wind the covered yarn 300 guided by the guiding assembly 200; wherein, an adjustment slot 111 is provided on the frame side plate 110; the winding assembly 120 and the guiding assembly 200 are respectively installed in the adjustment slot 111. The modular adjustment slot 111 structure is adopted to improve the adjustment accuracy of the distance between the winding assembly 120 and the guiding assembly 200.

[0036] Please continue to refer to Figure 1 and Figure 2 , the guiding assembly 200 includes: a bottom plate 210; a guiding wheel 220, which is arranged on the incoming line side of the bottom plate 210; a removing assembly 230, which is arranged between the winding assembly 120 and the guiding wheel 220; the removing assembly 230 includes: an outer sleeve 231 and an inner core tube 232 inserted into the outer sleeve 231; a first wire groove 231a is arranged radially outward on the inner wall of the outer sleeve 231; a second wire groove 232a is arranged radially inward on the outer wall of the inner core tube 232.

[0037] Among them, the removing assembly 230 includes two working conditions: the guiding working condition, the first wire groove 231a and the second wire groove 232a are arranged staggeredly. At this time, the covered yarn 300 passes through the first wire groove 231a, the fluff of the covered yarn 300 is removed, and at the same time, the incoming line guiding is completed; the wiring working condition, after wiring is completed, the outer sleeve 231 is rotated by an external force to make the first wire groove 231a communicate with the second wire groove 232a, so as to switch the two yarns after wiring to the first wire groove 231a for conveying.

[0038] By placing the splicing ends of the two covered yarns 300 at both ends of the two wire grooves, after splicing, the two wire grooves are made to communicate, so that the joint area is changed from the traditional single-point force to the full-circumference support of the inner wall of the wire groove, effectively dispersing the shear force during the dynamic winding process; at the same time, controlling the collinearity of the two yarns after splicing and the knotting point spacing to be greater than the length of the outer sleeve 231, avoiding the breakage problem caused by the sudden change of tension during the start of winding, thereby reducing the disconnection risk at the wiring point.

[0039] At the same time, the design of double knotting is adopted to avoid the overall wire breakage caused by the loosening of one of the knotting points, increasing the reliability of the winding device.

[0040] It should be noted that the height of the first wire groove 231a is R1; the height of the second wire groove 232a is R2; the wire diameter of the covering yarn 300 is R3; wherein, R2 < R1 < R3, and the units of R1, R2, and R3 are mm.

[0041] Through the design of the dimensions of R1, R2, and R3, it not only ensures the tight fitting of the two yarns during joint splicing but also effectively removes the residual hairiness.

[0042] Among them, in the wiring working condition, the wiring steps are as follows: Leave the previous covering yarn 300 in the first wire groove 231a and make the previous covering yarn 300 expose from both ends of the first wire groove 231a; Pass the next covering yarn 300 through the second wire groove 232a and make the next covering yarn 300 expose from both ends of the second wire groove 232a; Complete the splicing of the two ends of the two covering yarns 300 by external force.

[0043] Adopting the wiring process of segmented reservation + collinear splicing solves the problem of phase mismatch caused by single-point splicing in the related technology. By controlling the knotting point spacing > the length of the outer sleeve 231, the instantaneous tension peak during winding startup is avoided, the tensile strength of the joint is increased, and the strict requirements for continuity in high-speed winding are met.

[0044] Please refer to Figure 2 and Figure 3 , the removing component 230 further includes an outer guide block 233; the outer guide block 233 is provided with a through hole 233a; the outer sleeve is rotatably arranged in the through hole 233a.

[0045] Please refer to Figure 3 and Figure 4 , in an optional implementation manner, a clamping block 231b is arranged on the outer wall of the outer sleeve 231; an annular clamping groove 233b is arranged at the matching position of the through hole 233a and the clamping block 231b; the outer sleeve 231 is limited with the outer guide block 233 through the cooperation of the clamping block 231b and the annular clamping groove 233b.

[0046] Through the axial limit design of the clamping block 231b and the annular clamping groove 233b, the self-locking function of the outer sleeve 231 under the guiding working condition is realized. The misalignment angle error of the wire groove is reduced, and the mis-triggering action caused by vibration is avoided, thereby ensuring the stability of the guiding path of the covering yarn 300.

[0047] Among them, the guiding path of the covering yarn is as shown by the dotted line in Figure 1 .

[0048] Specifically, please refer to Figure 4 andFigure 5 The clamping block 231b is axially provided with a groove 231b1 along the outer sleeve 231; an elastic abutting block 231b2 is arranged in the groove 231b1; one end of the elastic abutting block 231b2 is elastically connected to the groove 231b1 through a return spring 231b3, and the other end abuts against the side wall of the annular card slot 233b, so as to prevent the outer sleeve 231 from rotating when guiding the winding of the covered yarn.

[0049] Please refer to Figure 1 and Figure 2 The removing assembly 230 further includes a hairiness removing block 240; the hairiness removing block 240 is provided with a removing hole; when guiding the winding of the covered yarn, the covered yarn led out from the guiding wheel 220 passes through the removing hole to remove the hairiness, and then enters the first wire groove 231a of the outer sleeve 231 to perform secondary removal of the remaining hairiness. By adopting the secondary cleaning method, the hairiness on the surface of the covered yarn is removed, and the number of hairiness on the surface of the covered yarn during winding is reduced.

[0050] It should be noted that the end of the inner core tube 232 is connected to the removing block; when the outer sleeve 231 is rotated by an external force, the inner core tube 232 remains stationary. The inner core tube 232 performs secondary removal of the hairiness, and at the same time ensures the stability of the outer sleeve 231 during rotation.

[0051] Among them, in the guiding working condition, the second wire groove 232a of the inner core tube 232 is located above the first wire groove 231a of the outer sleeve 231.

[0052] The embodiment of the present disclosure further provides a winding method applied to the covered yarn winding device as described above. Please refer to Figure 6 In the guiding working condition, the winding method includes: S110: Guide one end of the covered yarn through the first wire groove 231a through the guiding wheel 220 by an external force; S120: Rotate the outer sleeve 231 to displace the second wire groove 232a from the first wire groove 231a; S130: Pull the covered yarn exposed from the first wire groove 231a by an external force and feed it into the winding body 100 to start winding; Please refer to Figure 7 In the wiring working condition, the wiring method includes: S210: Leave the previous covered yarn in the first wire groove 231a and make the previous covered yarn expose from both ends of the first wire groove 231a; S220: Pass the next covered yarn through the second wire groove 232a and make the next covered yarn expose from both ends of the second wire groove 232a; S230: Knot the two ends of the two covered yarns respectively by an external force to complete the splicing; S240: Rotate the outer sleeve 231 by an external force to communicate the first wire groove 231a with the second wire groove 232a, and at the same time make the two covered yarns collinear, and make the wire length between the two knotting points greater than the length of the outer sleeve 231, so as to avoid breaking the covered yarn when the winding body 100 starts.
