However, it should be appreciated that many implementation-specific decisions must be made in the development of any such practical embodiment in order to achieve the developer's specific objectives, for example, compliance with system and business related constraints, and these Restrictions may vary from implementation to implementation. Moreover, it should also be appreciated that while development work can be very complex and time consuming, such development work is merely a routine task for those skilled in the art having the benefit of this disclosure.

The processing steps are omitted, and representations and descriptions of components and processes known to those of ordinary skill in the art that are not relevant to embodiments of the present invention are omitted.

Referring to Figure 1, an elastic fiber production guide device includes a first godet roller 1, at least one second godet roller 2, and at least one feed roller 4 is disposed below any of the second godet rollers 2. At least one winding device 5 is provided below each of the feed rollers 4.

When the elastic fiber production guide wire device is in an operating state, the first godet roller 1 and the tow 3 drawn from the exit of the tunnel 7 are connected to the at least one second godet roller 2, and the feed roller 4 passes through the tow. 3 is connected to the reel 50 in the corresponding winding device 5.

In an embodiment of the present invention, a second godet roller may be included. One or more feed rollers are disposed under a second godet roller, and one or more feeds are disposed below each feed roller. Rolling device. Alternatively, the elastic fiber production guide device of the embodiment of the present invention may also include a plurality of second godet rollers, "at least one feed roller is disposed below any of the second godet rollers", such as: One or more feed rollers are disposed under the godet roller; alternatively, one or more feed rollers may be disposed only under portions of the second godet roller, and no feed roller may be disposed under the remaining second godet roller . When a plurality of feed rollers are disposed under a second godet roller, at least one winding device is disposed below each of the feed rollers, for example, a winding device can be disposed under the partial feed roller, while remaining A plurality of winding devices are disposed below the feed roller. Therefore, the embodiment of the present invention may include multiple implementation manners, and the implementation manner is very flexible and universal.

Unlike non-elastic fibers, elastic fibers are stretched during the winding process due to the tension they are subjected to. In the conventional winding technology, the degree of freedom of the tow is large, and the tension required to avoid the tow wound on the godet of the godet roller must be increased, so that the pre-draw force or the residual drafting force of the fiber after winding is large. This affects the fiber of the elastic fiber Physical properties such as degree; further, if fabrics such as fabrics are prepared from elastic fibers having uneven physical properties after winding, the fabrics produced may be produced due to differences in pre-draw strength or residual drafting force of the elastic fibers after winding. Wrinkles and even drums occur, affecting the quality of the fabric. However, the embodiment of the present invention proposes a new solution that is different from the conventional technology. By providing a feeding roller between the second godet roller and the winding device, the existing spinning position can be removed from the second godet roller. The elastic fiber of the winding device has a small degree of freedom, thereby reducing the tension required to prevent the tow from being wound around the godet roller, and the feeding roller is a roller structure, and the frictional force of the roller structure to the tow is small, so The elastic fiber can be wound under a small tension without increasing the friction as much as possible, and the elastic fiber is prevented from being stretched and thinned due to excessive tension during the winding production process, and the elastic fiber winding is reduced. The post-draw force or residual drafting force is favorable for ensuring the consistency of the fiber fineness after winding, thereby improving the product quality of the elastic fiber and the quality of the fabric such as cloth prepared based on the elastic fiber.

The technical solutions provided by the embodiments of the present invention can be applied to the winding control of various elastic fibers. As a kind of elastic fiber with larger elasticity, the spandex fiber adopts the technical scheme provided by the embodiment of the invention to perform winding control, and has better consistency in physical properties such as fiber fineness after winding than the conventional technology. Guarantee. Hereinafter, the technical solution described by taking spandex fiber as an example is also applicable to other types of elastic fibers, and will not be described again.

In the above technical solution, the feeding roller 4 may be located directly below the second godet roller to divide the free path of the tow into two segments, reducing the degree of freedom of the tow. Alternatively, the feed roller 4 may be located obliquely below the second godet roller 2 connected thereto by the tow 3 to achieve the above object, while the feed roller is disposed obliquely below the second godet roller to change the filament The direction of the wire path of the bundle can reduce the lateral width of a guide wire device, making the spacing of each spinning position smaller, saving space, and also facilitating the arrangement of more winding devices in the same space.

And/or, the second godet roller 2 can be located obliquely above the first godet roller 1. The spandex fiber needs to be shaped by the godet roller from the tunnel. Optionally, a large angle of the first godet roller is required for better shaping, and the second godet is disposed on the first godet. Inclined upward, the wrap angle of the tow with the first godet roller and the second godet roller can be increased to facilitate the shaping of the tow during the winding process.

In the above technical solution, in order to increase the productivity, at least two feeding rollers 4 may be disposed in parallel below any of the second godet rollers 2; and/or at least two are disposed in parallel below each feeding roller 4. a winding device 5.

The optional form of the specific settings is as follows:

Referring to Figure 1, two feed rolls 4 are disposed in parallel below a second godet 2, and a take-up device 5 is provided below each feed roll 4. Optionally, two feed rollers 4 are arranged parallel to the second godet roller 2 and located at the same horizontal plane. The technical solution makes the length of the spandex fiber from the exit of the ramp to the winding device in the existing spinning position the same or as the same as possible, thereby ensuring the uniform physical properties of the spandex fiber produced from the winding device and improving the spandex fiber. Product quality; in addition, the tow from the second godet is fed through the feed roller into the reel of the corresponding winding device, reducing the tension of the tow and ensuring the quality of the fiber.

Using the fiber production guide wire device shown in FIG. 2, FIG. 3 and FIG. 4, on the basis of realizing the corresponding technical effects of the embodiment shown in FIG. 1, the productivity of the single spinning position of the spandex can be further improved, and the unit energy can be reduced. Consumption can also reduce unit space. The embodiment shown in Figures 2 - 4 can each achieve the arrangement of four winding devices.

Referring to Fig. 2, four feeding rollers 4 are arranged in parallel below a second godet roller 2, and a winding device 5, a feeding roller 4 and a winding device 5 are provided below each feeding roller 4. A correspondence.

Referring to Figure 3, the number of feed rollers 4 disposed below a second godet roller is less than the number of winding devices 5, and the plurality of winder devices share a feed roller, for example, four under one second godet roller. The winding device, and each of the two winding devices shares a feeding roller 4, the equipment cost is the lowest, and the technical solution satisfies the fiber of the plurality of tows coming out from the same second godet when entering different winding devices The length of the tow is the same from the exit of the ramp to the different winding devices, and the degree of freedom is small, so that the physical properties are as uniform as possible, thereby improving the product quality of the fiber. This solution can increase the capacity of a single spinning position, such as an increase in the number of fibers, thereby increasing the yield of the product.

Referring to FIG. 4, the second godet roller 2 is two, and the plurality of second godet rollers 2 are disposed in parallel above the first godet roller 1, and two feeds are provided below each of the second godet rollers 2. Into the roller 4, a winding device 5 is provided below each of the feeding rollers 4. The technical solution satisfies that the plurality of tows coming out from the same second godet roller have the same length of the fibers when entering different winding devices, and the degree of freedom is small, so that the physical properties are as uniform as possible, thereby improving the product quality of the fiber. In the embodiment of the invention, the feeding rollers can also be arranged at different horizontal planes and arranged in parallel. The provision of a plurality of second godet rolls and corresponding feed rolls can increase the capacity of a single spinning position, such as an increase in the number of fibers, thereby increasing the yield of the product.

The technical solution provided by the embodiment of the present invention can achieve the effect. Compared with the prior art, the prior art tow has a large degree of freedom, and in order to prevent the tow from being wound on the godet during the winding process, the tow has to be provided. Larger tension, while larger tension affects physical properties such as the fineness of elastic fibers such as spandex fibers. And According to the technical solution provided by the embodiment of the present invention, by providing a feeding roller between the second godet roller and the winding device, the degree of freedom of the tow is small, so that the tension between the tows is appropriately reduced and is not easily entangled. On the godet roller; especially for the spandex fiber, it has great elasticity. If the tension is too large, the fiber is stretched and thinned, affecting the fineness thereof, and the technical solution provided by the embodiment of the invention can ensure the fiber. Quality, and more winding devices can be placed in one spinning position to increase productivity.

Optionally, the feed roller has a linear velocity greater than the linear velocity of the second godet connected to the tow, and the feed roller is disposed adjacent to the winding device that is connected thereto by the tow. The solution sets the feed roller close to the winding device connected to it through the tow (ie, the distance of the feed roller from the second godet connected to the tow, the winding distance from the feed roller and its winding through the tow The distance of the device is far apart. Under this premise, the position of the feed roller can be adjusted such that the difference between the linear velocity of the reel of the winding device and the linear velocity of the second godet is less than a second set threshold.

Generally, the spinning speed of one spinning position refers to the linear speed of the reel of the winding device. In the prior art production, the linear velocity of the first godet is less than the linear velocity of the reel, and the linear velocity of the second godet is greater than the linear velocity of the first godet; the actual reduction of the wire tension is achieved by the first guide The linear speed of the wire roller is realized. Because the speed of the first godet roller is increased, it is necessary to increase the linear velocity of the second godet roller to ensure that the tow between the two rollers has a tension for oiling, but in the prior art The linear speed of the two godet rolls cannot be raised too high to prevent the free length of the wire after the second godet roller from being small and wound onto the godet.

After the feeding roller is added in the technical scheme of the embodiment of the present invention, the feeding roller linear velocity can be made larger than the second godet roller linear velocity, so that the tow has a certain tension without being wound onto the godet roller, and the feeding roller is to be fed. Close to the winding device, the free section of the tow is small, so that even if the tension of the tow is small, the free section is small, so that the tow is not wound around the feeding roller.

Further, the second set threshold may be as small as possible, for example, the second set threshold is any one of [0, 0.15 V1], where V1 represents the linear velocity of the second godet. The technical solution considers the position of the feeding roller, and the speed coordination of the feeding roller and the second godet roller and the first godet roller, wherein the feed roller has a linear velocity V2 greater than a second guide connected thereto through the tow. The linear velocity V1 of the wire roller causes the tow between the feeding roller and the second godet roller to have a large tension, thereby ensuring that the tow is not wound on the second godet; in addition, the feeding roller Proximity to the winding device connected to the tow thereof, that is, the feeding roller is far from the second godet roller and close to the winding device, so that the linear velocity V3 of the winding device approaches the linear velocity of the second godet as close as possible V1, such that the tow which is stretched between the second godet roller and the feed roller by a large tension is transferred between the feed roller and the reel of the winding device, and is stretched due to the reduced tension The tow will shrink properly, thus The solution reduces the pre-draw force or residual drafting force of the fibers after winding of the fibers after winding, thereby ensuring physical properties such as fiber fineness after winding.

In the above technical solution, for the case where a plurality of feeding rollers are disposed under one second godet roller, the plurality of feeding rollers may be arranged in parallel, that is, including a plurality of feeding rollers arranged in parallel in different horizontal planes; The infeed rolls are arranged in parallel on the same horizontal plane. For example, in the case where two feeding rolls are arranged under one second godet roller as shown in FIG. 1, the two feeding rolls 4 can be arranged in parallel on the same horizontal plane, and the setting device is simple to manufacture. Uniform, practical and beautiful layout, low cost.

In the above technical solution, in the case where a plurality of winding devices are disposed under one feeding roller, the plurality of winding devices may be arranged in parallel, that is, the plurality of winding devices are arranged in parallel in different horizontal planes; and the plurality of winding devices are also included. In the same horizontal plane, in the case where two winding devices are arranged under one feeding roller as shown in FIG. 3, the two winding devices 5 can be arranged in parallel on the same horizontal plane, and the installation device is simple and uniform in manufacturing, and is practically arranged. Beautiful and low cost.

In the above technical solution, optionally, the difference between the distances of the tows from the ramps to the different winding devices is less than the first set threshold. The smaller the first set threshold is, the better, as the first set threshold is any value between [0, 0.2L], and L is between the first godet and the nearest second godet. distance. This solution is advantageous for ensuring that the lengths of the tows from the exit of the ramp to the winding device are the same or substantially the same, thereby contributing to the quality of the fibers.

For example, referring to Fig. 1, two feeding rollers 4 are arranged in parallel below a second godet roller 2, and a winding device 5 is disposed below each feeding roller 4, and the tows 3 are different from the outlets of the tunnel 7 respectively. The winding paths of the winding device 5 are the same, thereby ensuring that the length of the tow of the exit to the winding device is the same, ensuring the quality of the fiber. The technical solution corresponds to two feeding rollers under one second godet roller, and the tows are respectively the same from the exits of the tunnel to the different winding devices, so that the winding device corresponding to each feeding roller is wound up. The fibers have the same length, thereby ensuring the uniform physical properties of the spandex fibers produced from the winding device and improving the product quality of the spandex fibers.

For example, referring to FIG. 3, two feeding rollers 4 are disposed in parallel below the second godet roller 2, and two winding devices 5 are disposed under each feeding roller 4, and the tows 3 are respectively connected from the exits of the tunnels. The different paths of the different winding devices 5 are the same. The technical solution provides two winding devices under one second feeding roller. Since the tows 3 are the same from the exit of the tunnel to the different winding devices 5, the two windings corresponding to one feeding roller The fibers of the coils of the device have the same length, thereby ensuring the uniform physical properties of the spandex fibers produced from the winding device and improving the product quality of the spandex fibers.

In the above technical solution, the diameters of the first godet roller, the second godet roller, and the feed roller can be selected according to actual needs. For example, the diameters of the first godet roller, the second godet roller, and the feed roller are all the same or different; or, referring to FIG. 1, the first godet roller 1 and the second godet roller 2 have the same diameter so that Uniform in manufacturing, practical and aesthetically pleasing, and/or, the diameter of the feed roller 4 is smaller than the diameter of the second godet roller 2, since the diameters of the first godet roller and the second godet roller are both larger than the diameter of the feed roller, The contact area between the first godet roller and the second godet roller and the tow is large, and the shaping of the subsequent tow is easy, the diameter of the feeding roller is smaller than the diameter of the second godet roller, and the resistance to the tow is small. Helps to change the direction of the tow.

In the above technical solution, the first godet roller, the second godet roller, and the feed roller may be disposed on the same bracket or different parts according to actual needs. Optionally, the first godet roller 1 and the second godet roller 2 are disposed on the godet roller bracket, and the feeding roller 4 is disposed on the godet roller bracket, that is, the first godet roller 1 and the second guide Both the wire roller 2 and the feed roller 4 are disposed on the same godet roller holder. The solution fixes the feed roller on the godet holder, which is easy to process and easy to implement. It is of course also possible to fix the feed roller to a different frame or to fix the feed roller to the winding device so that the feed roller is located above the winding device, which is very flexible and easy to lay out.

In the above technical solution, optionally, an oiling roller 6 is disposed between the first godet roller 1 and the second godet roller 2, and the first godet roller 1, the second godet roller 2, and the oiling roller 6 are both Set on the same godet holder. The solution refuels the fibers by the oiling roller, reduces the friction force received during the fiber transmission, and sets the first godet roller 1, the second godet roller 2 and the oiling roller 6 on the same godet roller bracket. Easy to process and easy to implement.

The embodiment of the invention also provides the use of any of the above fiber production guide wire devices in the production of spandex fibers.

Due to the greater elasticity of the spandex fibers, the spandex fibers are guided onto the godet rolls to the winding device, which results in different lengths of spandex fibers from each winding device to the bypass, ie spandex fibers on each winding device The number of godet rolls passed is different, which will result in the physical properties of the spandex fibers wound on each winding device not being the same. For example, the strength, elongation and the like of the spandex fibers will be different; the elasticity of the embodiment of the present invention is adopted. The fiber production guide wire device has a small free length of the spandex fiber from the godet roller to the winding device, and does not need to use a large tension to wind up, does not affect the fineness of the spandex fiber, and ensures the consistency of the physical properties of the spandex fiber and improves the consistency. The quality of spandex fiber. Meet the high quality requirements for spandex fiber.

Referring to Figure 1, a spandex fiber spinning position includes the above-mentioned fiber production guide wire device and a crucible Lane 7, the first godet roller 1 is connected to the tunnel 7 through the tow 3, the oil roller 6 disposed in the direction of the spandex fiber filament path in the first godet roller 1, and the second godet roller disposed above the upper oil roller 6 2, two feeding rollers 4 are respectively disposed below the second godet roller 2, and under each feeding roller 4 are two winding devices 5; the first godet roller 1 changes the direction of the filament of the spandex fiber The role of the spandex fiber from the ramp 7 is also set, and the first godet roller 1 and the second godet roller 2 form a fixed wire path to realize the setting of the oiling roller 6; Refueling of spandex fibers.

The tows coming out of the tunnel 7 are sequentially passed through the first godet roller 1, the upper oil roller 6, the second godet roller 2, and the feeding roller 4, enter the winding device 5, and are wound around the spool 50. According to the spinning position of the spandex fiber of the embodiment of the invention, one ramp corresponds to a plurality of winding devices, and the setting of the feeding roller ensures that the length of the spandex fiber in each winding device is uniform, and in the case of ensuring the quality of the spandex fiber, The feed roller divides the second godet and the tow in the winding device into two segments, thereby reducing the tension of the two segments. The degree of freedom of the tow is small, and the spandex fiber is not wound onto the godet or the feed roller during normal winding of the spandex fiber.

In the embodiment of the invention, the first godet is used to change the direction of the tow from the ramp.
