[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] like Figure 1 As shown, the present invention provides a technical solution: an integrated spinning device with a traction device, comprising a spinning frame 1, wherein a twisting mechanism and a winding mechanism are arranged inside the spinning frame 1, and a drafting mechanism is arranged outside the spinning frame 1, and the drafting mechanism comprises a rear drafting zone, a middle drafting zone, a front drafting zone and a quality inspection zone in sequence, and the quality inspection zone is located between the drafting mechanism and the spinning frame 1.

[0039] The rear stretching zone includes a first traction assembly 2 and a second traction assembly 3, and the rotation speed of the roller 6 on the second traction assembly 3 is greater than the rotation speed of the roller 6 on the first traction assembly 2. Generally, the rotation speed of the roller 6 on the second traction assembly 3 is several times the rotation speed of the roller on the first traction assembly 2. The rear stretching zone preliminarily stretches the fiber strips to reduce the thickness difference of the fiber strips.

[0040] The middle drafting zone includes the second traction assembly 3 and the third traction assembly 4, where the rollers 6 have different rotation speeds, and the rotation speed of the rollers 6 on the third traction assembly 4 is greater than that of the rollers 6 on the second traction assembly 3. Generally, the rotation speed of the rollers 6 on the third traction assembly 4 is several times that of the rollers on the second traction assembly 3. The middle drafting zone further stretches the fiber strips to reduce the unevenness of the fiber strips.

[0041] The front drafting zone includes the third traction assembly 4 and the fourth traction assembly 5, and the speed of the roller 6 on the fourth traction assembly 5 is greater than the speed of the roller 6 on the third traction assembly 4. Generally, the speed of the roller 6 on the fourth traction assembly 5 is dozens to one hundred times the speed of the roller on the third traction assembly 4. The front drafting zone stretches the fiber strip to the final fineness.

[0042] The quality inspection area is used to detect whether the fiber strips are uniform after being stretched in the front stretching area, and to control the uniformity of the fiber strips by adjusting the rotation speeds of the rollers on the first traction assembly 2, the second traction assembly 3, the third traction assembly 4, and the fourth traction assembly 5 respectively.

[0043] The four traction assemblies have the same composition structure, except that the speed settings of the rollers 6 are different. They all include a fixed plate 1 7 and a fixed plate 2 8. The fixed plate 1 7 is rotatably connected with two upper and lower gears that mesh with each other, namely, a gear 1 9 and a gear 2 10. The gear 2 10 is driven by a traction motor 11 installed on the fixed plate 1 7. Two rotatable rollers 6 are arranged between the fixed plate 1 7 and the fixed plate 2 8, one of the rollers 6 is connected to the gear 1 9, and the other roller 6 is connected to the gear 2 10.

[0044] The traction motor 11 drives the gear 2 10 to rotate. Since the gear 2 10 is meshed with the gear 1 9, the gear 1 9 is driven to rotate. The rotation directions of the two are opposite. The two gears respectively drive the two rollers 6 between the fixed plate 1 7 and the fixed plate 2 8 to rotate. The two rollers 6 rotate in opposite directions. The two rollers 6 on the same traction assembly have the same rotation speed, and the rollers 6 on different traction assemblies have different rotation speeds.

[0045] It also includes a speed sensor 12, the probe of the speed sensor 12 is aimed at any one or more of the traction motor 11 shaft, gear 1 9 shaft, gear 2 10 shaft and roller 6 shaft. Because the traction motor 11 shaft, gear 1 9 shaft, gear 2 10 shaft and roller 6 shaft all rotate synchronously, the speed of roller 6 can be obtained by detecting one of them. When more than two of them are detected, the speed comparison can be performed to detect whether the transmission has slippery phenomena or other faults, which is suitable for belt transmission; the speed sensor 12 adopts a Hall speed sensor, an optical speed sensor or other non-contact sensor.

[0046] The quality inspection area is provided with an industrial vision camera 13, which is aimed at the fiber strips between the fourth traction assembly 5 and the spinning frame 1. The industrial vision camera 13 can convert the optical signal into an orderly electrical signal. It has high image stability, high transmission capacity and high anti-interference ability, and can work stably in various complex environments. In addition, its shutter time is short, and it can capture high-speed moving fiber strips.

[0047] The first traction component 2, the second traction component 3, the third traction component 4, and the fourth traction component 5 are all installed on a base 14, and a processing module 15 is provided on the base 14. The processing module 15 determines whether the fiber strips are uniform according to the information obtained by the industrial vision camera 13, and controls the speed of the traction motor 11 on the first traction component 2, the second traction component 3, the third traction component 4, and the fourth traction component 5.

[0048] In the spinning process, the process of drawing and thinning the yarn is called drafting. The drawing and thinning of the yarn is the result of the relative movement of the fibers in the yarn along the length direction. Therefore, the essence of drafting is the relative movement of the fibers along the axial direction of the yarn. Its purpose is to draw and thin the yarn to reach the specified linear density. During the drafting process, the relative movement of the fibers makes the fibers parallel and straight.

[0049] The cross section of a yarn is composed of a certain number of fibers. According to actual tests and mathematical statistics, the number of fibers in a yarn cross section with a certain linear density becomes a distribution. Even if the yarn raw material is very uniform and no additional unevenness is produced during production, the yarn will still have uneven thickness. This unevenness is random.

[0050] The random unevenness value increases as the yarn density decreases or the draft ratio increases, that is, the average number of fibers in the yarn cross section decreases. In the finished spun yarn, the smaller the yarn density, the greater the yarn unevenness. The random unevenness of the yarn is the lowest unevenness, so it is sometimes called the ideal unevenness of the yarn. By adjusting the draft ratio, the random unevenness of the fiber strips can be effectively controlled.

[0051] Embodiment 2:

[0052] like Figure 2 As shown, on the basis of embodiment 1, it also includes: a slide groove 16 is set on the base 14, any three of the first traction component 2, the second traction component 3, the third traction component 4, and the fourth traction component 5 are located in the slide groove 16, and the traction components located in the slide groove 16 can be horizontally displaced to adjust the distance between two adjacent traction components and fix them, and a distance sensor 26 for detecting distance changes is set between two adjacent traction components.

[0053] The first traction component 2 is fixed on the base 14, and a translation mechanism 1 is arranged between the first traction component 2 and the second traction component 3. The translation mechanism 1 drives the second traction component 3 to move along the slide groove 16 relative to the first traction component 2; the translation mechanism 1 includes a threaded rod 17 and a translation motor 19 installed on the first traction component 2, and a threaded sleeve 18 installed on the second traction component 3. When the translation motor 19 drives the threaded rod 17 to rotate along the threaded sleeve 18, since the first traction component 2 is fixed, it can drive the threaded sleeve 18 and the second traction component 3 to translate synchronously.

[0054] A second translation mechanism is provided between the second traction component 3 and the third traction component 4, which can drive the third traction component 4 to move along the slide groove 16 relative to the second traction component 3; the second translation mechanism includes a threaded rod 20 and a translation motor 22 installed on the third traction component 4, and a threaded sleeve 21 installed on the second traction component 3. When the translation motor 22 drives the threaded rod 20 to rotate along the threaded sleeve 21, the second traction component 3 is limited by the first traction component 2, and can drive the third traction component 4 to translate.

[0055] A translation mechanism 3 is arranged between the third traction assembly 4 and the fourth traction assembly 5, which can drive the fourth traction assembly 5 to move relative to the third traction assembly 4 along the slide slot 16; the translation mechanism 3 includes a threaded rod 3 23 and a translation motor 3 25 installed on the fourth traction assembly 5, and a threaded sleeve 3 24 installed on the third traction assembly 4. When the translation motor 3 25 drives the threaded rod 3 23 to rotate along the threaded sleeve 3 24, the third traction assembly 4 is limited by the second traction assembly 3, and can drive the fourth traction assembly 5 to translate. Through multiple translation assemblies, the processing module 15 can achieve the purpose of automatically adjusting the distance between each traction assembly.

[0056] Due to the differences in fiber properties and straightening arrangement, especially the presence of short fibers, even if the mechanical state is relatively normal, the force (drafting force) on the fibers on the yarn during the drafting process continues to change, causing the fiber displacement deviation and unevenness. This unevenness is called drafting unevenness or drafting waves. Drafting waves are manifested as unevenness in shorter segments, which is the main factor affecting the evenness of the spun yarn. One of the main factors in the formation of drafting unevenness is the gauge.

[0057] For certain products and certain drafting patterns, there is a certain reasonable range of gauges. Too large or too small will affect the normal movement of the fiber and increase the unevenness of the yarn. This embodiment can effectively avoid the uneven drafting of the limit strip caused by an unreasonable gauge range by adjusting the distance between two adjacent traction components, that is, the roller gauge, also known as the grip distance.

[0058] Embodiment three:

[0059] like Figure 4 and 5 As shown, on the basis of the second embodiment, it also includes: a rotating shaft 27 is arranged on the gear 9, a rotating shaft 28 is arranged on the roller 6, a rotating shaft 3 29 is rotatably connected to the fixed plate 28, the rotating shaft 27 is connected to one end of the rotating shaft 28 through an Oldham coupling 1 30, and the other end of the rotating shaft 28 is connected to the rotating shaft 3 29 through an Oldham coupling 2 31;

[0060] The cross slider coupling is mainly composed of two cross sliders and two slider seats. The two shafts are connected to each other through the sliders to achieve power transmission and angular displacement compensation. The roller 6 is connected to the gear and the rotating shaft of the fixed plate 28 through two cross slider couplings, which can not only realize the transmission of the traction motor 11 to the roller 6, but also adjust the position of the roller 6 within a certain range.

[0061] It also includes a pressurizing device, which applies pressure to the second rotating shaft 28 to control the pressure applied by the roller 6 to the fiber strip.

[0062] The pressurizing device includes a hydraulic rod, and the two hydraulic rods are respectively connected to the two ends of the rotating shaft 28 of one of the rollers 6 through bearing sleeves, and the hydraulic rod pushes the roller 6 by extending, so that the roller 6 moves toward the other roller 6 to press the fiber strip;

[0063] A pressure sensor is provided on the hydraulic rod to monitor the pressure between the two rollers 6 on the same traction assembly. The two pressure sensors can monitor the change of pressure, as well as the eccentricity of the roller 6, abnormal shaking and other phenomena.

[0064] Specifically, the pressurizing device includes a bearing sleeve 1 32, a hydraulic rod 1 33, a bracket 1 34, a pressure sensor 1 35, a bearing sleeve 2 36, a hydraulic rod 2 37, a pressure sensor 2 38 and a bracket 2 39. The bearing sleeve 1 32 is sleeved on one end of the rotating shaft 28, and the bearing sleeve 2 36 is sleeved on the other end of the rotating shaft 28.

[0065] One end of the hydraulic rod 33 is connected to the bearing sleeve 32, and the other end is connected to the bracket 34. A pressure sensor 35 is arranged between the bracket 34 and the hydraulic rod 33. The bracket 34 is fixedly mounted on the fixing plate 7.

[0066] One end of the hydraulic rod 2 37 is connected to the bearing sleeve 2 36 , and the other end is connected to the bracket 2 39 . A pressure sensor 2 38 is arranged between the bracket 2 39 and the hydraulic rod 2 37 . The bracket 2 39 is fixedly mounted on the fixing plate 2 8 .

[0067] One of the main factors for uneven drafting is the pressure on roller 6. The pressure will affect the drafting efficiency or the normal movement of the fiber. Insufficient pressure will affect the drafting efficiency and the weight of the yarn. In severe cases, the coarse yarn cannot be drafted, resulting in thick and thin sections of the fine yarn. This embodiment can not only monitor the pressure on roller 6, but also adjust the pressure on roller 6 through the pressure device according to the uneven drafting detected by the industrial vision camera 13, so as to better improve the drafting efficiency, reduce the uneven drafting of the fiber strips, and improve the spinning quality.

[0068] Embodiment 4:

[0069] A sealing cover 40 is provided on the drawing mechanism, and an environmental control mechanism is provided inside the sealing cover 40 . The sensors include a temperature sensor 41 and a humidity sensor 42 installed inside the sealing cover 40 , and a hot air duct 43 , a cold air duct 44 , and a dehumidification duct 45 connected to the sealing cover 40 .

[0070] Since the temperature and humidity are too high during the spinning process, it is easy to cause the rollers or leather rollers to be entangled and produce uneven cotton strips. Therefore, the environmental control mechanism monitors the working environment of the drafting mechanism in the sealing cover 40 through sensors, and adjusts its working temperature and working humidity to avoid uneven fiber strips caused by the environment.

[0071] Embodiment five:

[0072] The industrial vision camera 13 is used to monitor the random uneven defects, uneven stretching defects and mechanical uneven defects of the fiber strips; the industrial vision camera 13 performs image recognition through a data comparator or a neural network algorithm.

[0073] The processing module 15 adjusts the speed of the traction motor 11 on the first traction assembly 2, the second traction assembly 3, the third traction assembly 4, and the fourth traction assembly 5 according to the random unevenness defects detected by the industrial vision camera 13, so as to adjust the drafting multiples of each drafting zone; even if the yarn raw material is very uniform and no additional unevenness is generated during production, the yarn still has uneven thickness, which is the random unevenness.

[0074] The processing module 15 detects uneven drafting defects based on the industrial vision camera 13. Due to the differences in fiber properties and straightening arrangement states, especially the presence of short fibers, even if the mechanical state is relatively normal, the fiber force (drafting force) on the yarn during the drafting process continues to change, causing the fiber displacement deviation to form unevenness. This unevenness is uneven drafting or drafting waves. The drafting waves are manifested as unevenness in shorter segments. The roller spacing of each drafting zone is adjusted by the translation mechanism, and the pressure of the roller 6 is adjusted by the pressure device;

[0075] The processing module 15 detects the mechanical unevenness defects based on the industrial vision camera 13. The periodic or non-periodic unevenness caused by abnormal drafting components or mechanical factors is called mechanical unevenness or mechanical wave, that is, the movement of the roller jaws and the control of the roller jaws on the fiber movement are unstable. The pressure sensor is used to detect whether the roller 6 has abnormal pressure changes caused by vibration.

[0076] The roller jaws are the distance between two rollers on the same drafting assembly. If the position of the roller jaws is unstable, the roller spacing will change over time, resulting in uneven yarn. For example, if the lower roller is a perfect circle, but the roller is eccentric, bent, and the roller coating is uneven, the roller's center of rotation is not its center. When the roller rotates, the roller center moves in a circle around the center of rotation, and the roller jaws also move back and forth, making the spun yarn thicker or thinner. The greater the eccentricity of the upper roller, the greater the distance the jaws move, and the more obvious the thicker or thinner the spun yarn is. In addition, if the lower roller is eccentric or bent, or the roller torsional vibration occurs, the surface speed of the lower roller will be uneven, and the draft multiple between the rollers will change frequently, which will seriously affect the unevenness of the spun yarn.

[0077] By detecting the pressure changes at both ends of roller 6 through two pressure sensors, it is possible to determine whether it has irregular movement, shaking, or eccentricity, whether there is abnormal pressure change caused by vibration, etc., so as to adjust the state of roller 6 in time to avoid mechanical uneven defects.

[0078] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
