Description

Technical Field

[0001] The present application relates to the technical field of spinning false twist machinery, and in particular to a yarn false twist device. Background Art

[0002] In the textile processing process, the quality and stability of yarn have always been the key factors affecting product quality. Generally speaking, yarns that have been treated with false twist have better performance.

[0003] False twist is an operating technique in textile machinery. Specifically, it involves fixing the two ends of a rope and twisting it in the middle. In this process, one side of the rope will be twisted tighter and tighter, while the other side will also be twisted tighter, but the twist direction is opposite. Therefore, although the twisting operation is performed on the rope, the total number of twists does not change and remains 0. This is the basic principle of false twist.

[0004] Although the traditional false twist structure can achieve the false twist treatment of yarn to a certain extent, after the yarn is compounded with loose fibers, if it is only false twisted once, the false twisted yarn after treatment will still have the problem of insufficient stability, and the bond between the loose fibers and the yarn is still not strong enough, thus affecting the quality of the final product of the yarn. Therefore, the development of a device that can false twist and fix the yarn efficiently and stably in actual production has become an urgent problem to be solved in the field of textile machinery. Utility Model Content

[0040] The embodiment of the present application discloses a yarn false twisting device, which is used to false twist the yarn of composite loose fibers to make it more firm and stable. The device can be fixed on a frame for use. Figure 1 As shown, a yarn false twist device includes: a false twist mechanism, the false twist mechanism includes a first false twist component 1 for twisting the yarn and a second false twist component 2 for reinforcing the yarn, and in this embodiment, the second false twist component 2 is located below the first false twist component 1.

[0041] The first false twist assembly 1 includes a hollow motor 3 and a first false twister 4. The hollow motor 3 is fixedly connected to the first false twister 4 and the hollow motor 3 drives the first false twister 4 to rotate to perform the first false twist of the yarn. The first false twister 4 includes a first connecting seat 41 and a first false twist arm 42.

[0042] The rotating shaft 31 of the hollow motor 3 is a hollow structure, and the first connecting seat 41 is a hollow structure. The rotating shaft 31 and the first connecting seat 41 are fixedly connected and communicated with each other.

[0043] In this embodiment, the first connecting seat 41 is a hollow cylindrical structure and is made of plastic. The first connecting seat 41 and the rotating shaft 31 are connected in such a way that the first connecting seat 41 is wrapped around the outer periphery of the rotating shaft 31 .

[0044] The first false twist arm 42 is located below the first connecting seat 41 and is fixedly connected to the first connecting seat 41 .

[0045] In this embodiment, the first false twist arm 42 is made of metal, and the first connection seat 41 and the first false twist arm 42 are connected in a plastic-wrapped metal fixed connection.

[0046] Reference Figure 2 The first false twist arm 42 includes a first support rod 421 and a first limiting rod 422 . The first support rod 421 and the first limiting rod 422 are perpendicular to each other. One end of the first support rod 421 is fixedly connected to the first connecting seat 41 .

[0047] In this embodiment, since the first connecting seat 41 is a hollow cylindrical structure, in order to ensure the stability of the connection between the first false twist arm 42 and the first connecting seat 41, as shown in FIG. Figure 2 As shown, two first connecting rods 423 are fixedly connected between the first supporting rod 421 and the first connecting seat 41, and the two first connecting rods 423 are fixedly connected to the two ends of the diameter of the circular cross-section of the first connecting seat 41, and the cross-section is funnel-shaped to maintain the stability and balance of the first false twist arm 42.

[0048] The other ends of the two first connecting rods 423 converge on a straight line passing through the center of the circular cross-section and perpendicular to the circular cross-section and are fixedly connected to one end of the first support rod 421. The other end of the first support rod 421 is connected to the middle part of the first limiting rod 422. The first support rod 421 and the first limiting rod 422 are in an inverted T shape, and the connection between the first support rod 421 and the first limiting rod 422 is smoothly transitioned through an arc surface.

[0049] In this embodiment, the first support rod 421, the first limiting rod 422 and the first connecting rod 423 are integrally formed, and the assembled first false twist arm 42 is in an inverted T shape.

[0050] During implementation, the two yarns compounded with the loose fibers pass through the hollow motor 3 from the top of the rotating shaft 31 of the hollow motor 3, and come out from the first connecting seat 41 fixedly connected to the bottom end of the rotating shaft 31. The two yarns are separated by the first supporting rod 421, bypass the two sides of the first supporting rod 421, and are supported by the arc-shaped transition connections on both sides of the connection between the first supporting rod 421 and the first limiting rod 422. When the hollow motor 3 rotates at high speed, the first false twister 4 rotates accordingly to perform the first false twist on the two yarns.

[0051] The second false twist assembly 2 is located below the first false twist assembly 1, and is used to receive the yarn after the first false twist, and perform a second false twist to fix the false twisted yarn and another fixed yarn.

[0052] The second false twist assembly 2 includes a hollow spindle 5 and a second false twister 6. The hollow spindle 5 is fixedly connected to the second false twister 6, and the hollow spindle 5 drives the second false twister 6 to rotate for secondary false twisting. The structure of the hollow spindle 5 is stable and can withstand the tension of the yarn and various forces in the false twisting process.

[0053] like Figure 1 As shown, a hollow wire reel 7 is also sleeved on the hollow shaft 51 of the hollow spindle 5, and the hollow wire reel 7 is clearance-matched with the hollow shaft 51. A fixing wire is wound on the hollow wire reel 7, and the fixing wire enters the cavity of the hollow spindle 5 from the top end of the hollow shaft 51.

[0054] During implementation, after the first false twisting, the two yarns are twisted into one, which is referred to as the false-twisted yarn in the following description. The false-twisted yarn is passed through the top of the hollow shaft 51 of the hollow spindle 5, and at the same time, the fixed line on the hollow wire coil 7 is also passed through the top of the hollow shaft 51. The false-twisted yarn and the fixed line pass through the cavity of the hollow spindle 5 and come out from the bottom end of the hollow spindle 5.

[0055] The bottom end of the hollow spindle 5 is fixedly connected with a second false twister 6 . The second false twister 6 includes a second connecting seat 61 and a second false twist arm 62 . The second false twist arm 62 is located below the second connecting seat 61 and fixedly connected to the second connecting seat 61 .

[0056] In this embodiment, the second false twister 6 has the same structure as the first false twister 4 . Similar to the first false twister 4 , the second connecting seat 61 is fixedly connected to the bottom end of the hollow shaft 51 of the hollow spindle 5 .

[0057] like Figure 3As shown, the second false twist arm 62 includes a second support rod 621, a second limiting rod 622 and a second connecting rod 623. The two ends of the second support rod 621 are fixedly connected to the middle part of the second limiting rod 622 and the second connecting rod 623 respectively. The second support rod 621 and the second limiting rod 622 are in an inverted T shape. The connection between the second support rod 621 and the second limiting rod 622 is a smooth arc. The other end of the second connecting rod 623 is fixedly connected to the second connecting seat 61.

[0058] During implementation, the false-twisted yarn and the fixed line come out from the bottom end of the hollow spindle 5, are separated by the second support rod 621, bypass both sides of the second support rod 621, and are supported by the arc-shaped transition connection on both sides of the second support rod 621. A driving member for driving the hollow shaft 51 to rotate is provided on the outside of the hollow spindle 5, and the second false twister 6 rotates with the hollow shaft 51 to perform a second false twist on the two yarns.

[0059] The purpose of the second false twist is to wrap and fix the false twisted yarn with a fixed thread, so that the final twisted yarn is more stable and of better quality.

[0060] This embodiment also includes a material receiving mechanism, which is located below the false twisting mechanism. Figure 4 As shown, the material receiving mechanism includes a traction assembly and a material receiving assembly, and the traction assembly includes a first driving member 8 and a reducer 9 driven by the first driving member 8 and a roller 10 connected in sequence.

[0061] The first driving member 8 is a motor, whose output shaft is connected to the input shaft of a reducer 9 . The reducer 9 can adjust the output speed of the motor to meet the working requirements of the roller 10 .

[0062] The output shaft of the reducer 9 is connected to the input shaft of the roller 10 through a coupling, which is not shown in the figure. Through this connection mode, the power of the reducer 9 can be transmitted to the roller 10 through the coupling, driving the roller 10 to rotate.

[0063] In this embodiment, the first driving member 8, the reducer 9 and the coupling can provide stable and reliable power support for the roller, ensuring that it can generate sufficient traction to pull the yarn. Under the driving action, the roller can achieve precise control and smooth transmission of the yarn, providing an important guarantee for the efficient operation of the textile machinery.

[0064] During the implementation, the final yarn obtained after the secondary false twist enters the receiving mechanism below, and the first driving member 8 and the reducer 9 provide power to the roller to start rotating. When the yarn passes through the roller 10, due to the friction on the surface of the roller 10, the yarn is subjected to a forward pulling force, i.e., traction, thereby ensuring that the yarn can smoothly pass through the surface of the roller 10, and then the subsequent receiving operation is carried out.

[0065] Reference Figure 5 The receiving assembly is located downstream of the entire device, and includes a rotatable receiving drum 11 and a second driving member 12 for driving the receiving drum 11. The receiving drum 11 is used to collect the yarn pulled from the surface of the roller 10. There is also a protective layer on the surface of the receiving drum 11. The protective layer is made of soft material such as cotton cloth, which can reduce the friction between the yarn and the receiving drum 11 and prevent the yarn from being damaged during the collection process.

[0066] The receiving drum 11 is fixedly connected to the rotating shaft of the second driving member 12. The receiving drum 11 is driven by the second driving member 12, which is a motor that can adjust the rotation speed according to the processing speed and length of the yarn to ensure that the yarn can be collected neatly and orderly.

[0067] When this embodiment is implemented, the two yarns pass through the hollow motor 3 and then enter the first false twister 4 separately. The first false twister 4 rotates at high speed with the hollow motor 3 to false-twist the two yarns to form a false-twisted yarn. The false-twisted yarn enters the hollow spindle 5 below, and a fixed line enters therewith. The false-twisted yarn and the fixed line come out from the bottom end of the hollow spindle 5 and enter the second false twister 6 separately. The second false twister 6 rotates at high speed with the hollow spindle 5 to false-twist the false-twisted yarn and the fixed line, and the fixed line is used to increase the stability of the false-twisted yarn, so that the yarn finally produced is of higher quality.

[0068] The yarn after secondary false twisting passes through roller 10, is pulled by the friction force of the surface of roller 10, and is collected by receiving roller 11 driven by second driving member 12 after passing through the surface of roller 10, so as to realize automatic collection and stable conveying of yarn.

[0069] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
