DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1-3 As shown, this embodiment discloses a yarn processing system, including a yarn feeding device 1, a yarn conveying device 2, a yarn feeding device 4, and a bulking device 5; the yarn feeding device 1 is disposed above the yarn feeding device 2; the yarn feeding device 2 is provided with an inclined yarn feeding channel 3; the yarn feeding device 4 is provided with a yarn feeding portion 41, which is eccentrically disposed on the yarn feeding device 4; the yarn feeding device 2 is rotatably connected to the yarn feeding portion 41; and the yarn feeding device 4 is rotatably connected to the bulking device 5. The phrase "the yarn feeding portion 41 is eccentrically disposed on the yarn feeding device 4" means that the yarn feeding portion 41 is offset from the center of the yarn feeding device 4. When the yarn feeding device 4 is circular, the offset refers to the offset from the center of the circle; when the yarn feeding device 4 is square or rectangular, the offset refers to the offset from the center of the yarn feeding device. The yarn feeding device 4 can be the cover of the bulking chamber, and the bulking device 5 can be the body of the bulking chamber.

[0031] The yarn a fed into the yarn feeding device 1 passes through the yarn feeding channel 3 in the yarn feeding device 2 and enters the bulking device 5 for bulking. The bulked yarn a enters the next process from the yarn outlet hole (not shown in the figure) of the bulking device 5. The yarn outlet hole is generally set at the bottom of the bulking device 5.

[0032] The state of yarn a entering the yarn delivery channel 3 is as follows Figure 4 As shown, the arrangement of the expanded yarn a in the expansion device 5 is as shown in FIG. Figure 5 The present invention can realize the rotation connection between the yarn feeding device 2 and the yarn feeding part 41 through the bearing. At this time, the yarn feeding device 2 can rotate relative to the yarn feeding part 41. By setting an inclined yarn feeding channel 3 in the yarn feeding device 2 and the yarn feeding device 2 being rotatable relative to the yarn feeding part 41, the yarn a can be curled in the yarn feeding channel 3, which is conducive to the formation of regular yarn coils (i.e., Figure 5 The present invention can realize the rotation connection between the yarn feeding device 4 and the bulking device 5 through the bearing. At this time, the bulking device 5 can rotate relative to the yarn feeding device 4. When the bulking device 5 can rotate relative to the yarn feeding device 4 and the yarn feeding part 41 is eccentrically arranged on the yarn feeding device 4, the yarn a can enter the bulking device 5 from different positions of the bulking device 5, so that the bulked yarn loop (i.e. Figure 5 The small circles arranged in sequence in the bulking device 5 fall at different positions of the bulking device 5. As the bulking device 5 rotates one circle, the yarn loops falling at different positions of the bulking device 5 can also be arranged in a ring shape in the bulking device 5 (i.e. Figure 5 The puffed yarn a can enter the next process in an orderly manner at the yarn outlet of the puffing device 5.

[0033] The yarn feeding device 1 of this embodiment includes a first yarn feeding wheel 11 and a second yarn feeding wheel 12. The first yarn feeding wheel 11 and the second yarn feeding wheel 12 rotate in opposite directions. The first yarn feeding wheel 11 and the second yarn feeding wheel 12 form a contact area 13. The contact area 13 is located on the circumference of the first yarn feeding wheel 11 and the second yarn feeding wheel 12. The contact area 13 is used to contact the yarn a, thereby realizing that the yarn a is fed into the yarn feeding device 2 through the rotation of the yarn feeding wheel. The first yarn feeding wheel 11 and the second yarn feeding wheel 12 at the contact area 13 can either contact each other (preferably elastic contact) or not contact each other, as long as they can contact the yarn a and realize the conveyance of the yarn a. In this embodiment, the first yarn feeding wheel 11 is preferably a driving wheel and can be driven by a driving device. The driving method here can be a driving method in the prior art and will not be described in detail. The second yarn feeding wheel 12 is preferably a passive wheel. The passive wheel is supported on the active wheel by an elastic member and rotates with the rotation of the active wheel. The elastic member can be a spring, a cylinder, an oil cylinder, etc., as long as it can ensure the smooth conveyance of the yarn a.

[0034] In this embodiment, the yarn feeding device 2 includes a support member 21 and a yarn feeding portion 22; the yarn feeding portion 22 is rotatably connected to the support member 21, and the yarn feeding channel 3 is located in the yarn feeding portion 22. The support member 21 plays a supporting and fixing role to ensure the stability of the rotation of the yarn feeding portion 22. Figure 2 As shown, the yarn feeding portion 22 is mounted within the support member 21 via a bearing. Preferably, a yarn guide nozzle 23 is provided on the support member 21. The yarn guide nozzle 23 extends between the first yarn feeding wheel 11 and the second yarn feeding wheel 12. The yarn guide nozzle 23 includes a first adapter portion 24 and a second adapter portion 25 disposed opposite each other. A rotational gap is formed between the first adapter portion 24 and the first yarn feeding wheel 11, and between the second adapter portion 25 and the second yarn feeding wheel 12. By extending the yarn guide nozzle 23 between the first yarn feeding wheel 11 and the second yarn feeding wheel 12, the yarn feeding device 2 can be positioned below the contact area 13, preventing the yarn a from being affected by airflow before passing through the contact area 13 and reaching the yarn feeding device 2, thereby ensuring smooth delivery of the yarn a into the yarn feeding device 2. The rotation gap formed between the first adapter part 24 and the first yarn feed wheel 11, and between the second adapter part 25 and the second yarn feed wheel 12 is 0-2mm, preferably 0.1-0.5mm. The rotation gap here can ensure that the yarn feed device 2 does not interfere with the rotation of the first yarn feed wheel 11 and the second yarn feed wheel 12, and can also ensure that the yarn guide mouth 23 is as close to the contact area 13 as possible.

[0035] The yarn processing system of the present invention also includes a first driving device and a second driving device. The first driving device is connected to the yarn feeding part 22 for driving the yarn feeding part 22 to rotate. The second driving device is connected to the bulking device 5 for driving the bulking device 5 to rotate. The transmission connection method here is not limited. For example, gears can be arranged outside the yarn feeding part 22 or the bulking device 5 to achieve transmission connection through gears.

[0036] In a preferred embodiment of this invention, the yarn processing system further includes a guide rod 6, which is located within the bulking device 5; the guide rod 6 is connected to the yarn feeding device 4 and is arranged along the axial direction of the bulking device 5. The provision of the guide rod 6 further prevents the yarn loops within the bulking device 5 from collapsing or tipping over, thereby preventing yarn disorder, and facilitating yarn routing continuity, thereby enabling continuous yarn bulking and improving bulking efficiency. Preferably, the surface roughness of the guide rod 6 is not greater than 3.2, and further preferably, the surface roughness of the guide rod 6 is not greater than 2. By controlling the smoothness of the surface of the guide rod 6, yarn hanging can be avoided; preferably, the diameter of the guide rod 6 gradually decreases from one end close to the yarn feeding device 4 to the other end, and the yarn a is expanded in the puffing device 5 and its volume increases. In order to adapt to its volume change, the diameter of the guide rod 6 changes accordingly, and the yarn passes through more smoothly; preferably, the interior of the guide rod 6 is hollow, and a side hole is provided on the upper side wall of the guide rod 6. The side hole is connected to the hollow inside the guide rod 6. After water or steam is passed into the hollow inside the guide rod 6, the water or steam can escape through the side hole, which can increase the humidity in the puffing device 5, improve the heat transfer efficiency, and facilitate the puffing of the yarn; preferably, a heating device is provided inside the guide rod. After the heating device is provided, the guide rod can also heat the environment of the puffing device 5 to improve the heat transfer efficiency.

[0037] Example 2

[0038] The similarities between this embodiment and embodiment 1 are not repeated here.

[0039] The difference is that Figure 6 As shown, the yarn feeding portion 22 of this embodiment is connected to the support member 21 via at least two bearings 26, with a bushing 27 provided between adjacent bearings 26. The provision of at least two bearings 26 ensures the stability of the yarn feeding portion 22 during rotation, and the provision of the bushing 27 supports the two bearings 26 while ensuring their coaxiality.

[0040] like Figure 7-8As shown, the yarn processing system also includes a yarn pressing member 7, which is located in the bulking device 5 and is connected to the yarn feeding device 4. By providing the yarn pressing member 7, the present invention can ensure that the yarn a moves stably in the bulking device 5, the yarn a is not easily blocked in the bulking device 5, and the yarn a is not easily disordered, which is conducive to smooth yarn routing and improved bulking efficiency. In a preferred embodiment of this embodiment, the yarn pressing member 7 is a spiral pressing plate to better achieve the yarn pressing effect. The spiral pressing plate is provided with a notch 71 for the yarn a to pass through. In another preferred embodiment of this embodiment, the yarn pressing member 7 is provided with a sensor that can be used to monitor the condition of the yarn a in the bulking device 5. When the yarn a accumulates too much or is blocked, an alarm is issued, and the speed of feeding the yarn into the bulking device 5 is reduced or the yarn is stopped. Preferably, the guide rod 6 and the yarn pressing member 7 are connected to the yarn feeding device 4 at the same time, which improves the bulking efficiency.

[0041] Example 3

[0042] This embodiment discloses a yarn processing method using the yarn processing system of the present invention, comprising the following steps:

[0043] The yarn a enters the yarn feeding device 2 through the yarn feeding device 1. As the yarn feeding device 2 rotates (specifically, the yarn feeding portion 22 rotates), the yarn a is curled in the yarn feeding channel 3. Figure 4 As shown;

[0044] The yarn a in the yarn feeding channel 3 enters the bulking device 5 through the yarn feeding portion 41 eccentrically arranged on the yarn feeding device 4. The bulked yarn a forms a yarn loop in the bulking device 5.

[0045] As the bulking device 5 rotates, the yarn coils are arranged in a ring shape around the middle of the bulking device 5, as shown in FIG. Figure 5 shown.

[0046] Because the yarn feed portion 41 is eccentrically arranged on the yarn feed device 4, when the bulking device 5 rotates, the expanded yarn loops will fall at different positions on the bulking device 5, and the yarn loops that fall in later will partially press on the yarn loops that fall in earlier. As the bulking device 5 rotates one circle, the yarn loops will also be arranged in a ring around the middle of the bulking device 5. When the bulking device 5 rotates to the next circle, the tail end of the last yarn loop in the lower ring layer is also the head end of the first yarn loop in the upper ring layer, and the first yarn loop in the upper ring layer is still partially pressed on the last yarn loop in the lower ring layer. As the bulking device 5 continues to rotate, the annular yarn loops will be stacked layer by layer (one layer for each rotation) in an orderly arrangement. The yarn processing method of the present invention fully utilizes the internal space of the bulking device 5, and at the same time, the yarn is arranged in an orderly manner within the bulking device 5. The yarn enters the next process in an orderly manner from the yarn outlet of the bulking device 5, and is less likely to cause entanglement, disorder, or breakage, thereby greatly improving production efficiency.
