The original covering yarn is short fiber and short fiber covering yarn developed by using cotton fiber as a sheath and polyester staple fiber yarn as a core, the existing covering yarn has more varieties, and can be divided into low-elasticity covering yarn and high-elasticity covering yarn according to the elasticity of the covering yarn, wherein the former means that the inner core material adopts fiber with smaller elasticity, and the formed final product has smaller elasticity, the latter means that the inner core material fiber adopts high-elasticity fiber, the outer covering fiber generally adopts low-elasticity fiber, and the low-elasticity fiber is adapted to the high elasticity of the inner core material fiber, so that the formed final product has large elasticity.
For the covering yarn of low-elasticity outer layer yarn covering high-elasticity inner core material yarn, because the difference of the elasticity of the inner layer yarn and the outer layer yarn is large, when the inner core high-elasticity yarn shrinks after the yarn is formed, the length of the outer layer covering yarn is surplus, and uneven intertwining loops are formed on the surface of the covering yarn, so that the appearance quality of the yarn is poor.

CN 205775052U discloses a controllable core yarn tension device, which comprises a machine body, a connecting rod, a core yarn barrel, a tensioner, a tension arm, a rubber pad, an iron sheet, a core yarn hole, an electromagnetic chuck, a pressure sensor, a controller, a godet wheel, a front roller, a middle roller, a rear roller, a bell mouth and a core-spun yarn barrel; the device controls the tension of the core yarn through a tensioner and automatically adjusts according to the change of the working state, but does not relate to the state change of the core yarn and the outer covering yarn with different elasticity in the covering yarn when the tension is changed.
In summary, there is no way to adjust the surface state of the covering yarn after forming in the prior art, and a new solution is needed to adjust the appearance state of the covering yarn composed of the high-elastic core yarn and the low-elastic covering yarn.
Disclosure of Invention
In view of the problems of the prior art, an object of the present invention is to provide a device and a method for uniformly mixing covering yarns, wherein the device adjusts the surface state of the covering yarns by re-stretching and shrinking the covering yarns after forming yarns, particularly, by treating the covering yarns composed of high-elasticity core yarns and low-elasticity covering yarns, so that the protrusions or knots formed on the surface of the covering yarns due to the elasticity difference between the inner core yarns and the covering yarns can be uniformly distributed, thereby fully improving the quality and appearance of the covering yarns.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a covering yarn mixing device which comprises a yarn unwinding assembly, a first roller, a second roller, a third roller and a yarn winding assembly which are sequentially connected.
In the invention, the device retreats the core-spun yarn after the finished yarn is wound, the core-spun yarn is redrawn and contracted by using the roller after unwinding, and the retraction state of the inner layer yarn and the outer layer yarn is consistent when the inner layer high-elasticity yarn and the outer layer low-elasticity yarn are contracted, so that the yarn bulges or the knotting distribution of the yarn formed on the surface of the yarn due to surplus length of the outer layer yarn are uniform, and the quality and the appearance of the finished yarn are fully improved; the device has the advantages of simple structure, simple and convenient operation and good adjustment effect.

As a preferred solution of the invention, the yarn unwinding assembly comprises, in sequence, a bobbin to be adjusted and a first guide ring.
Preferably, the central lines of the bobbin to be adjusted and the first thread guiding ring are located on the same vertical line, so that the yarn is guided out in an optimal posture.
Preferably, the distance between the upper end of the bobbin to be adjusted and the first yarn guiding ring is between 1.5 times of the maximum upper diameter of the bobbin to be adjusted and 2 times of the maximum lower diameter of the bobbin to be adjusted, and since the bobbin is generally in a truncated cone shape and the maximum lower diameter is larger than the maximum upper diameter, 2 times of the maximum lower diameter of the bobbin to be adjusted is larger than 1.5 times of the maximum upper diameter, for example, 1.5 times, 1.8 times, 2 times of the maximum upper diameter of the bobbin, 1.5 times, 1.8 times, 2 times of the maximum lower diameter of the bobbin, etc., but not limited to the values listed, and other values not listed in the range of values are also applicable.
According to the invention, the arrangement of the distance between the yarn barrel to be adjusted and the first yarn guide ring ensures that the balloon state formed when the yarn is led out is good, so that the unwound yarn can not generate additional friction with the surface of the yarn barrel when passing through the upper part of the yarn barrel and being unwound by the yarn barrel, and the condition that the tension state is uneven due to the additional friction with the surface of the yarn barrel in the unwinding process of the yarn is prevented; this is because the high elastic core-spun yarn is sensitive to force and is deformed unevenly by uneven external force, which affects the adjustment effect of the yarn state.
As a preferable embodiment of the present invention, the first roller, the second roller, and the third roller each independently include a top roller and a bottom roller.
Preferably, the lower roller is in active transmission, and the upper roller is in passive transmission.

In the invention, the first roller determines the speed of the core-spun yarn through setting the linear speed; setting the linear velocity of the second roller to be greater than that of the first roller, so that the yarn is further stretched to a greater extent in the process of passing through the second roller, namely, the inner core yarn and the outer covering yarn are fully stretched, and the linear velocity of the second roller is determined according to the stretching degree of the outer layer yarn of the core-spun yarn, so that the full stretching of the outer layer yarn is the standard for determining the velocity; the linear speed of the third roller is the same as that of the first roller, so that the core-spun yarn is reduced to an initial stretching state after passing through the third roller, the core-spun yarn is loosened after the speed is reduced, the high-elastic yarn of the inner layer and the low-elastic yarn of the outer layer contract simultaneously, but the retraction state of the yarn is consistent in the adjustment process, the problem that the retraction of different yarn sections is uneven due to different friction states of the surface of a yarn barrel in a conventional state does not exist, the protrusions or knots on the surface of the yarn can be uniformly distributed, and the appearance of the core-spun yarn is improved.
As a preferable technical solution of the present invention, the yarn winding assembly includes a second yarn guide ring and an adjusted bobbin in this order.
According to the invention, the position relation between the second yarn guide ring and the adjusted yarn barrel is determined according to the mode that the adjusted yarn is wound on the yarn barrel, and when the adjusted yarn adopts the winding mode that the yarn barrel rotates, the center lines of the adjusted yarn barrel and the second yarn guide ring are positioned on the same vertical line, so that the good package state of the adjusted yarn barrel is ensured; when the adjusted yarn adopts a mode that the second yarn guide ring rotates around the yarn cylinder, the center lines of the adjusted yarn cylinder and the second yarn guide ring are not on the same vertical line.
Preferably, the distance between the upper end of the adjusted package and the second yarn guiding ring is more than 2 times, for example, 2 times, 2.5 times, 3 times, 3.5 times or 4 times the maximum upper end diameter of the adjusted package, but the distance is not limited to the recited values, and other values not recited in the range of the values are also applicable.
In the invention, the adjusted yarn is wound into a yarn tube through a second yarn guide ring after the state adjustment is finished to form a final package; during the package process, the package can be formed by the active rotation of the yarn barrel, and also can be formed by the active rotation of the second yarn guide ring around the yarn barrel.
The arrangement of the distance between the adjusted yarn drum and the second yarn guide ring can ensure that the yarn is well packaged and is smoothly packaged when the yarn is packaged to different positions of the yarn drum, so that the phenomenon that unreasonable external force causes uneven deformation of the yarn to be packaged and the adjustment effect of the yarn state is influenced is avoided. In the yarn winding process, because the yarn winding speed is constant, the stress of the yarn is uniform, the relative position relationship consistency of the inner layer yarn and the outer layer yarn is good, the yarn protrusion on the surface can be further adjusted, or the knotting distribution of the yarn is uniform and consistent, and the yarn quality and the appearance can be fully improved.
