Description

Technical Field

[0001] The present invention relates to the field of textile technology, and in particular to an intelligent eddy current spinning system based on a viscose yarn drum. Background Art

[0002] Vortex spinning utilizes air vortexes to cohere and twist fibers that have been loosened into individual strands into yarn. The principle is that the fiber sliver is first opened into individual strands by a licker-in roller. The airflow then forces the fibers through tangential channels into a vortex tube, creating a fiber flow. Several air inlets are located tangentially around the vortex tube at appropriate locations. The tail end of the vortex tube is connected to an exhaust fan via a main air duct and filter screen, maintaining a constant negative pressure inside the tube. Ambient air enters the vortex tube at high speed through the tangential inlets. Because the airflow has a momentum moment with the central axis of the vortex tube, a vortex flow is formed within the tube. Alternatively, a set of spiral guide vanes can be used to guide air into the tube, creating a vortex flow. The high-speed vortex flow moves along the axial direction of the vortex tube, rotating in the same direction as the fiber flow fed through the tangential channels, achieving axial equilibrium. At the equilibrium position, the vortex flow propels the free yarn tail into a circular, high-speed rotation. The continuously fed fibers encounter the moving yarn tail and cohere onto it. When the free end rotates at high speed, the yarn is twisted.

[0003] The twisting efficiency of vortex spinning is relatively low, at around 30-50%. The coarser the yarn, the greater the frictional resistance of the free end rotation and the twisting torque, and the lower the twisting efficiency. According to the principles of fluid mechanics, the pressure is lowest at the center of the vortex core in a planar vortex. Therefore, during spinning, the seed yarn is easily drawn into the vortex tube through the center hole and spinning begins. The spun yarn is actively discharged by a pair of output rollers and wound onto a bobbin via a grooved drum or reciprocating yarn guide to form a package. Due to the bulky structure and good color absorption of vortex yarn, vortex spinning is particularly suitable for coarse and medium-gauge yarns made of pure or blended chemical fibers, used as pile yarns or for spinning core-spun yarns.

[0004] Chinese patent publication number: CN107663675B discloses a vortex spinning method, including: the sliver is drawn out from the feeding can by a guide roller and a guide pressure roller, the fibers in the sliver are sprayed with a solution of magnetic particles, and the fiber sliver with magnetic particles is fed into a vortex spinning device under the action of the rollers. The sliver is stretched and twisted in the vortex spinning device to form a yarn, which is led out by the front roller, enters the vortex tube for twisting again, and is finally output by the output roller. After the output roller, the yarn is passed through a rotating magnetic field and weakly twisted again, so that the fibers in the sliver are further attached to the yarn body, and the reciprocating yarn guide is wound into a finished yarn; it can be seen that the prior art has the following problems: it does not take into account the adjustment of the operating parameters of the vortex spinning system according to the specific situation of the yarn, which affects the quality of the yarn and thus affects the spinning efficiency of the vortex spinning. Summary of the Invention

[0005] To this end, the present invention provides an intelligent vortex spinning system based on a viscose yarn drum, which is used to overcome the problem in the prior art that the operating parameters of the vortex spinning system are adjusted without considering the specific conditions of the yarn, thereby affecting the quality of the yarn and further affecting the spinning efficiency of the vortex spinning.

[0006] To achieve the above objectives, the present invention provides an intelligent vortex spinning system based on a viscose yarn drum, comprising:

[0007] a feeding module comprising a licker-in roller for processing the fiber strip to form a plurality of fibers;

[0008] A vortex module, which is arranged at the output end of the supply module and is used to process the plurality of fibers into yarn, and includes a vortex tube for processing the plurality of fibers into a fiber flow, wherein the vortex tube is provided with a plurality of air inlet holes tangentially opened at corresponding positions, and the tail end of the vortex tube is connected to an exhaust fan through a main air duct and a filter screen;

[0009] A collecting module comprising a grooved drum arranged at the output end of the eddy current module to guide the yarn outputted therefrom, and a collecting roller arranged at the output end of the grooved drum to collect the yarn;

[0010] A detection module, comprising a visual detector disposed between the eddy current module and the collection module for obtaining the total length of longitudinal movement of the yarn in a single cycle, and an image acquirer for obtaining image information of the yarn; a light strip is disposed around the image acquirer for providing supplementary light when obtaining image information of the yarn;

[0011] The central control module is respectively connected to the corresponding components in the supply module, the eddy current module, the collection module and the detection module, and is used to determine whether the operating parameters of the supply module meet the preset standards based on the total length of the longitudinal movement of the yarn in a single cycle, and to make a secondary determination on whether the operating parameters of the supply module meet the preset standards based on the image information of the yarn when it is preliminarily determined that the operating parameters of the supply module do not meet the preset standards.

[0012] Furthermore, the central control module determines whether the operating parameters of the supply module meet the preset standards based on the total length of the longitudinal movement of the yarn in a single cycle when the operating time of the supply module reaches an integer multiple of the preset time, and adjusts the operating speed of the collecting roller to a corresponding value when it is determined that the operating parameters of the supply module do not meet the preset standards.

[0013] or, when it is preliminarily determined that the operating parameters of the supply module do not meet the preset standards, a secondary determination is made as to whether the operating parameters of the supply module meet the preset standards based on the image information of the yarn acquired by the image acquirer;

[0014] The central control module determines that the operating parameters of the supply module do not meet the preset standards, including, under the condition that the total distance is less than or equal to the first preset distance, the central control module increases the operating speed of the collecting roller to a corresponding value according to the difference between the first preset distance and the total distance.

[0015] And, under the condition that the total distance length is greater than the third preset distance length, the central control module reduces the running speed of the collecting roller to a corresponding value according to the difference between the total distance length and the third preset distance length.

[0016] Furthermore, the central control module converts the image information of the yarn acquired by the image acquirer into a grayscale image under the condition that it is preliminarily determined that the operating parameters of the supply module do not meet the preset standards to calculate the area of ​​each pixel point in the grayscale image that is within the preset grayscale threshold, and records the area as the grayscale area. The central control module determines whether the operating parameters of the supply module meet the preset standards based on the obtained grayscale area, and when it is determined that the operating parameters of the supply module do not meet the preset standards, the operating power of the exhaust fan is increased to a corresponding value according to the operating speed of the licker-in roller.

[0017] Alternatively, the distance between the licker-in roller and the fiber strip is adjusted down to a corresponding value according to the difference between the grayscale area and the second preset grayscale area.

[0018] Furthermore, the central control module is provided with several adjustment methods for the running speed of the collecting roller based on the difference between the calculated total distance length and the third preset distance length, and the adjustment range of the running speed of the collecting roller in each adjustment method is different.

[0019] Furthermore, the central control module controls the visual detector to obtain a second time the total length of the longitudinal movement of the yarn in a single cycle under the condition that the central control module completes the adjustment of the running speed of the collecting roller, and records the second-acquired total length as the moving length. The central control module determines whether the operating parameters of the supply module meet the preset standards based on the moving length, and when it is determined that the operating parameters of the supply module meet the preset standards, adjusts the running speed of the licker-in roller to a corresponding value according to the speed difference between the running speed of the collecting roller after adjustment and the running speed of the collecting roller before adjustment.

[0020] Alternatively, when it is determined that the operating parameters of the supply module do not meet the preset standards, the operating speed of the grooved drum is adjusted to a corresponding value according to the difference between the moving length and the preset moving length.

[0021] Furthermore, the central control module is provided with several adjustment methods for the running speed of the licker-in roller based on the calculated speed difference between the running speed of the collecting roller after adjustment and the running speed of the collecting roller before adjustment, and the adjustment range of the running speed of the licker-in roller in each adjustment method is different.

[0022] Furthermore, based on the calculated difference between the first preset distance length and the total distance length, several adjustment methods for the running speed of the collecting roller are provided, and the adjustment range of the running speed of the collecting roller in each adjustment method is different.

[0023] Furthermore, the central control module is provided with a plurality of adjustment modes for the operating power of the exhaust fan based on the acquired operating speed of the licker-in roller, and the adjustment range of the operating power of the exhaust fan in each adjustment mode is different.

[0024] Furthermore, the central control module is provided with several adjustment methods for the distance between the licker-in roller and the fiber strip based on the area difference between the calculated grayscale area and the second preset grayscale area, and the adjustment range of each adjustment method for the distance between the licker-in roller and the fiber strip is different.

[0025] Furthermore, the central control module is provided with several adjustment methods for the running speed of the grooved drum based on the difference between the calculated moving length and the preset moving length, and the adjustment range of the running speed of the grooved drum in each adjustment method is different.

[0026] Compared with the existing technology, the total length of the longitudinal movement of the yarn in a single cycle is obtained, that is, the vibration of the yarn is determined; the total length is proportional to the vibration intensity of the yarn; when the total length is too large, that is, the yarn is too tight due to the running speed of the collecting roller being too fast; the running speed of the collecting roller is adjusted, so the running speed of the collecting roller, that is, the rotation speed, is adjusted, and after the running speed of the collecting roller is lowered, the total length of the yarn is obtained for the second time. If the moving length of the yarn is still large, it is determined that the yarn is too tight due to the running speed of the groove drum being too high. In order to reduce the tension of the yarn and improve the production quality of the yarn, the running speed of the groove drum is adjusted, which further effectively improves the spinning efficiency of vortex spinning.

[0027] Furthermore, when the moving length meets the preset standard, the running speed of the licker-in roller, i.e., the rotational speed, is adjusted according to the specific adjustment of the collecting roller so that the running speed of the licker-in roller is balanced with the running speed of the collecting roller, thereby improving the production quality of the yarn and further effectively improving the spinning efficiency of the vortex spinning.

[0028] Furthermore, when the central control module preliminarily determines that the operating parameters of the supply module do not meet the preset standards, the image information of the yarn acquired by the image acquirer is converted into a grayscale image, and the area of ​​each pixel point in the grayscale image that is at the preset grayscale threshold is calculated, that is, the area of ​​the acquired yarn. When the grayscale area is too large, that is, because the distance between the fiber bundle and the licker-in roller is too large, there are more fiber bundles in the yarn that are not fully penetrated, thereby affecting the uniformity of the yarn. The part of the yarn that is not completely wrapped by the fiber bundle will cause the yarn to be tied, affecting the quality of the yarn. Therefore, the distance between the licker-in roller and the fiber strip is adjusted to further improve the spinning efficiency of vortex spinning.

[0029] Furthermore, when the grayscale area is large, that is, the fiber bundles fly and disperse because the operating power of the exhaust fan is too low, and the interweaving between the fiber bundles and other fiber bundles is not tight. Therefore, the operating power of the exhaust fan is adjusted, which further effectively improves the spinning efficiency of vortex spinning while ensuring the quality of the yarn.

[0043] The central control module is respectively connected to the corresponding components in the supply module, the eddy current module, the collection module and the detection module, and is used to determine whether the operating parameters of the supply module meet the preset standards based on the total length of the longitudinal movement of the yarn in a single cycle, and to make a secondary determination on whether the operating parameters of the supply module meet the preset standards based on the image information of the yarn when it is preliminarily determined that the operating parameters of the supply module do not meet the preset standards.

[0044] Specifically, the central control module determines whether the operating parameters of the supply module meet the preset standard yarn determination method based on the total length of the longitudinal movement of the yarn in a single cycle under the first preset condition, wherein:

[0045] The first yarn determination method is that the central control module determines that the operating parameters of the supply module do not meet the preset standards, and increases the operating speed of the collecting roller to a corresponding value according to the difference between the first preset distance length and the total distance length; the first yarn determination method satisfies that the total distance length is less than or equal to the first preset distance length;

[0046] The second yarn determination method is that the central control module determines that the operating parameters of the supply module meet the preset standards and controls the supply module to maintain the current operating parameters; the second yarn determination method satisfies that the total distance length is less than or equal to the second preset distance length and greater than the first preset distance length;

[0047] The third yarn determination method is that the central control module preliminarily determines that the operating parameters of the supply module do not meet the preset standards, and performs a secondary determination on whether the operating parameters of the supply module meet the preset standards based on the image information of the yarn acquired by the image acquirer; the third yarn determination method satisfies that the total distance length is less than or equal to the third preset distance length and greater than the second preset distance length;

[0048] The fourth yarn determination method is that the central control module determines that the operating parameters of the supply module do not meet the preset standards, and reduces the operating speed of the collecting roller to a corresponding value according to the difference between the total distance length and the third preset distance length; the fourth yarn determination method satisfies that the total distance length is greater than the third preset distance length;

[0049] The first preset distance length is less than the second preset distance length and less than the third preset distance length;

[0050] The first preset condition is that the operation time of the supply module reaches an integer multiple of the preset time.

[0051] The total length of the yarn is determined by continuously capturing images of the yarn using an image acquisition device. These images are then processed using image processing techniques. Algorithms such as edge detection, contour extraction, and feature point matching are used to analyze the yarn's trajectory. The yarn's trajectory is then tracked based on the image processing results. The change in yarn position within each frame is calculated to determine the yarn's reciprocating distance. Within a single cycle, the length of the reciprocating distance in each frame of the yarn image is accumulated to obtain the total length of the yarn.

[0052] Specifically, the central control module converts the image information of the yarn acquired by the image acquirer into a grayscale image under the third yarn determination mode, and calculates the area of ​​each pixel point in the grayscale image that is within a preset grayscale threshold. The central control module records the area as the grayscale area, and determines whether the operating parameters of the supply module meet the preset standard yarn secondary determination mode based on the obtained grayscale area, wherein:

[0053] The first yarn secondary determination method is that the central control module determines that the operating parameters of the supply module meet the preset standards and controls the supply module to maintain the current operating parameters; the first yarn secondary determination method satisfies that the grayscale area is less than or equal to the first preset grayscale area;

[0055] The third yarn secondary judgment method is that the central control module determines that the operating parameters of the supply module do not meet the preset standards, and adjusts the distance between the licker-in roller and the fiber strip to a corresponding value based on the difference between the grayscale area and the second preset grayscale area; the third yarn secondary judgment method satisfies that the grayscale area is greater than the second preset grayscale area.

[0056] When the central control module preliminarily determines that the operating parameters of the supply module do not meet the preset standards, the image information of the yarn acquired by the image acquirer is converted into a grayscale image, and the area of ​​each pixel point in the grayscale image that is at the preset grayscale threshold is calculated, that is, the area of ​​the acquired yarn. When the grayscale area is too large, that is, because the distance between the fiber bundle and the licker-in roller is too large, there are many fiber bundles in the yarn that are not fully penetrated, thereby affecting the uniformity of the yarn. The part of the yarn that is not completely wrapped by the fiber bundle will cause the yarn to be tied, affecting the quality of the yarn. Therefore, the distance between the licker-in roller and the fiber strip is adjusted to further improve the spinning efficiency of vortex spinning.

[0057] When the gray area is large, that is, the operating power of the exhaust fan is too low, causing the fiber bundles to fly and disperse, and the interweaving between the fiber bundles and other fiber bundles is not tight. Therefore, the operating power of the exhaust fan is adjusted. While ensuring the quality of the yarn, the spinning efficiency of vortex spinning is further effectively improved.

[0058] Specifically, the central control module calculates the difference between the total distance length and the third preset distance length under the fourth yarn determination mode, and records the difference as the length difference.

[0061] The third speed adjustment method is that the central control module uses a third preset speed adjustment coefficient to reduce the running speed of the collecting roller to a corresponding value; the third speed adjustment method satisfies that the length difference is greater than the second preset length difference.

[0062] Specifically, the central control module controls the visual detector to obtain the total length of the longitudinal movement of the yarn in a single cycle for a second time under the second preset condition, and records the total length of the twice obtained distance as the movement length.

[0063] The first yarn three-times determination method is that the central control module determines that the operating parameters of the supply module meet the preset standards, and adjusts the running speed of the licker-in roller to a corresponding value according to the speed difference between the running speed of the collecting roller after adjustment and the running speed of the collecting roller before adjustment; the first yarn three-times determination method satisfies that the moving length is less than or equal to the preset moving length;

[0064] The second yarn three-times determination method is that the central control module determines that the operating parameters of the supply module do not meet the preset standards, and adjusts the operating speed of the grooved drum to a corresponding value according to the difference between the moving length and the preset moving length; the second yarn three-times determination method satisfies that the moving length is greater than the preset moving length;

[0065] The second preset condition is that the central control module completes the adjustment of the running speed of the collecting roller in the fourth yarn determination mode.

[0066] The total length of the longitudinal movement of the yarn in a single cycle is obtained, that is, the vibration of the yarn is determined; the total length is proportional to the vibration intensity of the yarn; when the total length is too large, that is, the yarn is too tight due to the running speed of the collecting roller being too fast; the running speed of the collecting roller is adjusted, and after the running speed of the collecting roller is lowered, the total length of the yarn is obtained for the second time. If the moving length of the yarn is still large, it is determined that the yarn is too tight due to the running speed of the groove drum being too high. In order to reduce the tension of the yarn and improve the production quality of the yarn, the running speed of the groove drum is adjusted, which further effectively improves the spinning efficiency of vortex spinning.
