Description

Technical Field

[0001] The invention relates to the technical field of yarn defect detection, and in particular to a functional polyester-viscose yarn hairiness detection device and a detection method. Background Art

[0002] In the textile industry, yarn quality is one of the important indicators to measure the quality of textiles, and the hairiness of yarn directly affects its appearance and performance. As a common synthetic fiber yarn, the hairiness detection of polyester-viscose yarn is particularly important. Traditional hairiness detection methods mostly rely on manual visual inspection, which is not only inefficient but also easily affected by human factors, resulting in inconsistency and inaccuracy in the test results. With the advancement of science and technology and the development of automation technology, more and more automated testing equipment has been introduced into the textile industry to improve production efficiency and detection accuracy.

[0003] For example, the patent application with the prior art publication number CN117054427A belongs to the technical field of aramid yarn production equipment, and specifically relates to an aramid yarn appearance detection method and device; wherein, the aramid yarn appearance detection method includes the following contents: obtaining the appearance image information of the aramid yarn; judging whether the aramid yarn has defects based on the appearance image information; if so, controlling the alarm indication. The aramid yarn appearance detection method can perform real-time detection of the aramid yarn in the production process, and can achieve 24-hour uninterrupted detection, without missing every inch of the aramid yarn, and after detecting defects in the aramid yarn, it will promptly issue an alarm prompt, so that the technicians can analyze the causes according to the number and type of defects, and promptly improve the process to reduce the defective rate and improve the quality.

[0004] Although the existing technology has been able to achieve continuous detection of defects in aramid yarns by acquiring appearance image information of aramid yarns, this technology still has significant limitations in actual application scenarios. Specifically, in existing detection devices, the shooting angle of industrial cameras is usually limited to a single direction, which means that it can only capture image information of aramid yarns at a specific viewing angle. However, the hairiness defects of aramid yarns often present complex and diverse forms and may be distributed in various parts of the yarn. Therefore, it is difficult to achieve a comprehensive and detailed observation of aramid yarns by only detecting from a single-direction shooting angle. This limitation may not only cause certain defects to be missed, but also, due to the limitation of the shooting angle, the detected defect morphology may deviate from the actual situation, thereby affecting the accuracy and reliability of the detection. To this end, the present application proposes a functional polyester-viscose yarn hairiness detection device and detection method. Summary of the invention

[0014] Preferably, a plurality of feet are fixedly connected to the bottom of the detection box base.

[0015] Preferably, the tops and bottoms of the plurality of mounting plates are fixedly connected with light sources.

[0016] The present invention also provides a method for detecting hairiness of functional polyester-viscose yarn, comprising the following steps:

[0017] S1. When in use, the yarn can be continuously driven to move by operating the thread conveying assembly;

[0018] S2, at the same time, the transmission assembly is operated to change the position of the industrial camera, and when the industrial camera is placed directly opposite to the first blackboard, the transmission assembly is stopped, and the industrial camera is controlled to record the surface of the yarn to detect the surface velvet, and then the transmission assembly is continuously operated to drive the industrial camera to move to the directly opposite to the second blackboard, and the industrial camera is controlled to record the velvet on the outer surface of the yarn;

[0019] S3. When the transmission assembly is running at the same time, the air pump is used to spray air from the air outlet to the surface of the yarn, thereby improving the accuracy of its hairiness detection.

[0020] Preferably, the air outlet is placed directly opposite to the yarn.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting up a wire feeding component, especially a driving motor driving a multi-section worm to mesh with multiple worm gears, the yarn can be automatically driven to move without manual operation, thereby greatly improving the detection efficiency. The yarn is stably transported through the cooperation of the connecting roller and the line roller, ensuring the continuity and accuracy of the detection. The industrial camera cooperates with the light source to clearly capture the hairiness on the yarn surface, thereby improving the detection accuracy. By setting up the first blackboard and the second blackboard, the yarn can be fully detected from different angles to avoid detection blind spots. The transmission component, especially the double-headed motor driving gear meshing with the arc rack can flexibly change the position of the industrial camera so that it can be aimed at the first blackboard and the second blackboard respectively, thereby realizing a comprehensive detection of different parts of the yarn. The sliding connection of the slider in the guide groove ensures the stability and accuracy of the movement of the industrial camera.

[0023] 2. The air pump draws gas from the air ring shell through the suction pipe, and after filtering through the filter, it is ejected from the air outlet of the empty shell to blow the hair on the surface of the yarn straight. This design allows the originally bent or tilted hair to reach the actual length, thereby improving the accuracy of hair detection. When the double-headed motor is running, it drives the gear to rotate, and then drives the connecting strip and the notched brush ring to slide on the outer surface of the air ring shell. The notched brush ring rubs against multiple filter screens, automatically cleans the outer surface of the filter screen, prevents clogging, and extends the service life of the filter screen. Since the notched brush ring can automatically clean the filter screen, the frequency of manual cleaning is reduced. When the double-headed motor is located directly opposite the first blackboard or the second blackboard, it stops running, and the gear is also stationary at this time. The notched brush ring no longer cleans the filter screen, but allows gas to enter the air pump through the filter screen and eject from the air outlet to blow the hair on the surface of the yarn. When the double-headed motor stops running, the notched brush ring no longer blocks the gas from entering the air ring shell. At this time, the air pump can more smoothly absorb gas from the air ring shell, reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the first blackboard 301 and the second blackboard 302 to cooperate with each other, the surface hairiness of the yarn 107 can be fully detected. The first blackboard 301 and the second blackboard 302 are fixed at a vertical angle, and the inside of the cross frame 300 is provided with a transmission component for driving the mounting plate 304 to move. By setting the transmission component, the position of the industrial camera 303 can be effectively changed, so that it can continuously change its position, so that it is placed directly opposite the first blackboard 301 and the second blackboard 302, which is convenient for comprehensive detection of the yarn 107 and improves the shooting range.

[0037] For further information, see Figure 2 , Figure 5 as well as Figure 8 The transmission assembly includes a plurality of arc-shaped racks 310 fixedly connected to the inside of the horizontal frame 300, a plurality of mounting plates 304 are fixedly connected to one side of a double-headed motor 306, the output ends of the plurality of double-headed motors 306 are fixedly connected to a gear 309 meshing with the arc-shaped rack 310, a plurality of double-headed motors 306 are fixedly connected to one side of a straight frame 307, a sliding bar 308 is fixedly connected to the inside of the straight frame 307, and a guide groove 311 for the sliding bar 308 to slide and connect is opened inside the horizontal frame 300.

[0038] For further information, see Figure 3 , Figure 4 as well as Figure 5The line feeding assembly includes a plurality of line rollers 106 rotatably connected to the inside of the detection box seat 100, a plurality of rotating rods 104 are rotatably connected to the inside of the top plate 103, and a connecting roller 105 is installed on the outer surface of the plurality of rotating rods 104. The two ends of the yarn 107 are respectively fixedly connected to the inside of the connecting roller 105 and the line roller 106, and one end of the plurality of rotating rods 104 is fixedly connected to a worm gear 203. A protective shell 200 is fixedly connected to one side of the top plate 103, and a multi-section worm 202 is rotatably connected to the inside of the protective shell 200. A driving motor 201 fixedly connected to the multi-section worm 202 is fixedly connected to one end of the protective shell 200, and the multi-section worm 202 is meshed with a plurality of worm gears 203.

[0039] Specifically, when in use, the plurality of line rollers 106 are first rotated and connected to the inside of the detection box seat 100, and then the yarn 107 wound on the outer surface of the line roller 106 is pulled, and one end of the yarn 107 passes through the horizontal frame 300 and is connected to the connecting roller 105, and then the driving motor 201 is driven to drive the multi-section worm 202 to rotate, so that the multi-section worm 202 is meshed with the plurality of worm wheels 203 to drive the rotating rod 104 to rotate and drive the connecting roller 105 to rotate, thereby continuously driving the yarn 107 to move, and at the same time, the double-headed motor 306 is turned on to drive the gear 30 9 rotates, so that the gear 309 is engaged with the arc rack 310, thereby driving the slide bar 308 to slide in the guide groove 311, thereby changing the position of the industrial camera 303. When the industrial camera 303 is placed directly opposite the first blackboard 301, the double-headed motor 306 is stopped, and the industrial camera 303 is controlled to record the surface of the yarn 107 to detect the surface fuzz. Then, the double-headed motor 306 is continuously driven to rotate and drive the industrial camera 303 to move to the opposite side of the second blackboard 302, and the industrial camera 303 is controlled to record the fuzz on the outer surface of the yarn 107.

[0040] In summary, by setting up the line transmission component, especially the driving motor 201 drives the multi-section worm 202 to mesh with multiple worm wheels 203, the yarn 107 can be automatically driven to move without manual operation, thereby greatly improving the detection efficiency. The yarn 107 is stably transported through the cooperation of the connecting roller 105 and the line roller 106, ensuring the continuity and accuracy of the detection. The industrial camera 303 cooperates with the light source 305 to clearly capture the hairiness on the surface of the yarn 107, thereby improving the detection accuracy. By setting up the first blackboard 301 and the second blackboard 302, the yarn 107 can be fully detected from different angles to avoid the detection blind spot. The transmission component, especially the double-headed motor 306 drives the gear 309 to mesh with the arc rack 310, which can flexibly change the position of the industrial camera 303, so that it can be aligned with the first blackboard 301 and the second blackboard 302 respectively, thereby realizing a comprehensive detection of different parts of the yarn 107. The sliding connection of the slider 308 in the guide groove 311 ensures the stability and accuracy of the movement of the industrial camera 303.

[0041] Example 2: Please refer to Figure 8 , Fig. 9 as well as Fig.10 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a functional polyester-viscose yarn hairiness detection device, multiple mounting plates 304 are fixedly connected to both sides of an empty shell 400, one side of the empty shell 400 is provided with multiple air outlets 401, the interior of the mounting plate 304 is fixedly connected to an air pump 402 for filling air into the empty shell 400, the air inlet end of the air pump 402 is fixedly connected to an air suction pipe 403, one end of the air suction pipe 403 is fixedly connected to an air ring shell 404, the outer surface of the air ring shell 404 is fixedly connected to multiple filter screens 407, and one side of the multiple empty shells 400 is provided with multiple air outlets 401, the filter screens 407 can be cleaned by setting a notched brush ring 406, and the filter screen 407 can filter the gas to purify the gas entering the air pump 402, and the gas ejected from the air outlet 401 can blow the hairiness straight.

[0042] Furthermore, a connecting strip 405 is fixedly connected to the top of the gear 309 , a notched brush ring 406 is fixedly connected to one side of the connecting strip 405 , and the notched brush ring 406 is slidably connected to the outer surface of the air ring housing 404 .

[0043] It is worth mentioning that when the double-headed motor 306 is located opposite to the first blackboard 301 and the second blackboard 302, the double-headed motor 306 stops running and the gear 309 also stops running. The air pump 402 continues to run and will continuously draw gas from the air ring shell 404 and spray it out from the air outlet 401, thereby blowing the feathers on the surface of the yarn 107. By blowing the surface of the yarn, the airflow can straighten the originally bent or inclined feathers to reach their actual length. When the double-headed motor 306 continues to run, the notched brush ring 406 will continuously pass over the filter 407, thereby blocking the gas from entering the interior of the air ring shell 404 and cleaning the filter 407 at the same time.

[0044] Specifically, when the double-headed motor 306 is running, it drives the gear 309 to rotate, so that the gear 309 drives the connecting strip 405 to rotate together and drives the notched brush ring 406 to slide on the outer surface of the air ring housing 404, and at the same time rubs with multiple filter screens 407 to clean the outer surface of the filter screen 407, wherein the air pump 402 is continuously turned on to inhale air from the air ring housing 404 and spray it from multiple air outlets 401, and when the notched brush ring 406 continues to slide on the outer surface of the air ring housing 404, it can effectively block the gas entering the air ring housing 404, and when the gear 309 stops rotating, the notched brush ring 406 stops rotating, so that the filter screen 407 is connected to the outside, so that the gas passes through the air ring housing 404 into the air pump 402 and is sprayed from the air outlet 401, blowing to the surface of the yarn 107, thereby improving its feather detection accuracy.

[0045] In summary, the air pump 402 draws air from the air ring housing 404 through the air suction pipe 403, and after being filtered by the filter 407, it is ejected from the air outlet 401 of the empty housing 400 to straighten the hairiness on the surface of the yarn 107. This design allows the originally bent or tilted hairiness to reach the actual length, thereby improving the accuracy of hairiness detection. When the double-headed motor 306 is running, it drives the gear 309 to rotate, thereby driving the connecting strip 405 and the notched brush ring 406 to slide on the outer surface of the air ring housing 404. The notched brush ring 406 rubs against the multiple filter screens 407 to automatically clean the outer surface of the filter screens 407, prevent clogging, and extend the service life of the filter screens. Since the notched brush ring 406 can automatically clean the filter screens 407, the frequency of manual cleaning is reduced. When the double-headed motor 306 is located directly opposite the first blackboard 301 or the second blackboard 302, it stops running. At this time, the gear 309 is also stationary. The notched brush ring 406 no longer cleans the filter screen 407, but allows the gas to pass through the filter screen 407 into the air pump 402, and spray out from the air outlet 401 to blow the feathers on the surface of the yarn 107. When the double-headed motor 306 stops running, the notched brush ring 406 no longer blocks the gas from entering the air ring shell 404. At this time, the air pump 402 can more smoothly absorb gas from the air ring shell 404, reducing energy consumption.

[0046] Example 3: Please refer to Figures 1 to 10 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a functional polyester-viscose yarn hairiness detection method, comprising the following steps:

[0048] S2, at the same time, the double-headed motor 306 is turned on to drive the gear 309 to rotate, so that the gear 309 is meshed with the arc-shaped rack 310 to drive the slide bar 308 to slide in the guide groove 311, thereby changing the position of the industrial camera 303, and when the industrial camera 303 is placed directly opposite to the first blackboard 301, the double-headed motor 306 is stopped, and the industrial camera 303 is controlled to record the surface of the yarn 107 to detect the surface fluff, and then the double-headed motor 306 is continuously driven to rotate to drive the industrial camera 303 to move to the opposite side of the second blackboard 302, and the industrial camera 303 is controlled to record the fluff on the outer surface of the yarn 107;

[0049] S3. At the same time, when the double-headed motor 306 is running, it drives the gear 309 to rotate, so that the gear 309 drives the connecting strip 405 to rotate together and drives the notched brush ring 406 to slide on the outer surface of the air ring housing 404, and at the same time rubs with multiple filter screens 407 to clean the outer surface of the filter screens 407, wherein the air pump 402 is continuously turned on to inhale air from the air ring housing 404 and spray it from multiple air outlets 401, and when the notched brush ring 406 continues to slide on the outer surface of the air ring housing 404, it can effectively block the gas entering the air ring housing 404, and when the gear 309 stops rotating, the notched brush ring 406 stops rotating to connect the filter screen 407 with the outside, so that the gas passes through the air ring housing 404 into the air pump 402 and is sprayed from the air outlet 401, blowing to the surface of the yarn 107, thereby improving its feather detection accuracy.
