Abstract
Description
Technical Field
[0001] This application relates to the technical field of cotton processing, and in particular to a fiber length detection device applied to cotton spinning. Background Art
[0002] Cotton is widely used in the textile industry. The length of cotton fibers is a key indicator for evaluating the quality of textile processes, and it has an important impact on the texture of the finished product, the economic benefits of the enterprise, and cost management.
[0003] Currently, the methods for measuring the length of cotton fibers mainly include the traditional hand-stretching and ruler-measuring method and the measurement by a high-volume fiber tester. The hand-stretching and measuring method is to randomly extract a certain number of fibers from a cotton fiber bundle, lay the extracted fibers flat on a ruler, ensure that the fibers do not overlap, bend, and have the same direction, and use the ruler to measure along the length direction of the fibers to observe the length of the fibers with the naked eye; while the measurement by a high-volume fiber tester replaces the traditional manual inspection, performs rapid and high-volume detection of cotton, and improves the efficiency and accuracy of the inspection.
[0004] When detecting the fiber length in a laboratory, it helps that during the new product development process, the detection of the fiber length can be used as a reference for the selection and use of cotton spinning to meet the performance requirements of specific products. Based on the above-related technologies when detecting the fiber length in a laboratory, the following problems exist: The hand-stretching and measuring method depends on the skills and experience of the operator, and the measurement results may be affected by subjective factors, resulting in human errors, while the high-volume fiber tester is relatively large in size and is not suitable for use on the sampled cotton in the laboratory. Content of the Utility Model
[0005] In order to address the deficiencies of the existing technology, this application provides a fiber length detection device applied to cotton spinning, which can accurately measure the length of the sampled cotton spinning in the laboratory and provide reference data for the subsequent selection and use of cotton spinning.
[0006] This application provides a fiber length detection device applied to cotton spinning, which adopts the following technical solutions:
[0007] A fiber length detection device applied to cotton spinning includes a box body. A scanning plate is provided on the top of the box body. A clamping plate for clamping cotton spinning is provided on the top of the box body on one side of the scanning plate.

[0008] By adopting the above technical solution, after the cotton spinning sample is clamped by the clamping plate, it is placed on the top of the scanning plate. After the box cover is closed, the scanning head emits laser light and moves away from the clamping plate along the bottom surface of the box cover with the carding device, making the cotton spinning sample straighter and the detected fiber length more accurate. The image is handed over to the image recognition program of the computer, and the part with the largest length in the image is selected for measurement to obtain the length of the sample, realizing accurate length measurement of the sampled cotton spinning in the laboratory and providing reference data for the subsequent selection and use of cotton spinning.

[0014] By adopting the above technical solution, the air jetting member can jet gas onto the surface of the cotton spinning sample through the air inlet cavity and the air inlets and then discharge it through the air outlet, which can reduce the situation that the straight cotton spinning carded by the top comb catches the comb teeth and make the effect of the top comb carding the cotton spinning sample better.
[0015] The present application is further provided that: air guide channels are formed at the bottoms of several comb teeth of the top comb, and the angle between the air guiding surface formed by the air guide channels and the top of the comb teeth is 60° - 90°.
[0016] By adopting the above technical solution, when the gas jets onto the surface of the cotton spinning not carded by the top comb, it can reduce the error of the scanned image caused by fiber breakage and dispersion. At the same time, the gas generates pressure on the cotton spinning not carded, making the cotton spinning before carding not easy to warp and easier to be carded straight.
[0017] The present application is further provided that: a pressing plate is arranged at the bottom of the side of the comb teeth of the top comb facing the clamping plate, and the bottom surface of the pressing plate is parallel to the top surface of the scanning plate.

[0020] By adopting the above technical solution, the bottom of the clamping plate and the top of the box body can clamp the cotton spinning, making the cotton spinning not easy to shift when being carded by the top comb.

[0030] The following is a further detailed description of the present application in conjunction with the attached Figures 1 to 4 drawings.
[0031] Refer toFigures 1 to 4 , in this embodiment, a fiber length detection device applied to cotton spinning includes a box body 1. A scanning plate 2 is fixedly connected to the top of the box body 1. The top surface of the scanning plate 2 and the top surface of the box body 1 are in the same plane. A clamping plate 3 is arranged on one side of the scanning plate 2 at the top of the box body 1. The clamping plate 3 is used to clamp the cotton yarn. A box cover 4 is hinged on one side of the box body 1 and above the scanning plate 2. A carding device 5 is slidably connected to the bottom of the box cover 4. When the carding device 5 is working, it moves away from the clamping plate 3 from the side of the box cover 4 relative to the clamping plate 3, thereby realizing the carding of the cotton yarn sample, making the cotton yarn sample straighter. At the top of the carding device 5 for detection and above the scanning plate 2, a scanning head 6 is fixedly connected. The scanning head 6 is used to scan an image and upload the image to the computer's scanning head 6.
[0032] When the box body 1 is closed, the scanning head 6 starts to work, emits laser light onto the scanning plate 2, the scanning plate 2 reflects the light, the lens in the scanning head 6 focuses the received reflected light, and the light focused by the lens is finally projected onto the image sensor. The image sensor captures the image and converts it into an electrical signal, and uploads the electrical signal into the computer. After the computer preprocesses the image, it performs edge detection to identify the edge of the cotton yarn sample, and then segments the cotton yarn sample from the background, extracts the contour features of the cotton yarn sample, and tracks along the contour of the cotton yarn sample to confirm the starting point and ending point of the fiber, and finally measures the length of the fiber.
[0033] The scanning head 6 moves together with the carding device 5. Therefore, while the scanning head 6 scans the cotton yarn at the bottom, the carding device 5 combs the cotton yarn sample, making the cotton yarn sample scanned by the scanning head 6 flatter, accurately reflecting the length of the fiber. And after the carding device 5 finishes moving, the carding device 5 should block the cotton yarn sample so that the scanning head 6 at the top can scan the complete cotton yarn sample, realizing accurate length measurement of the sampled cotton yarn in the laboratory, providing reference data for the subsequent selection and use of cotton yarn. And since the carding device 5 works on the top surface of the scanning plate 2, the scanning plate 2 should be made of a material that is difficult to scratch.
[0034] Further, the carding device 5 includes a top comb 50. The top comb 50 is slidably connected to the bottom of the box cover 4 through a cylinder. When the top comb 50 moves away from the clamping plate 3 from the side of the box cover 4 relative to the clamping plate 3, it is the carding of the cotton yarn. The combed cotton yarn sample is straighter on the scanning plate 2, and the detected fiber length is more accurate. Preferably, the teeth of the top comb 50 are made of wood. The wooden teeth are not easy to damage the cotton fibers and are not easy to generate static electricity at the same time.
[0035] Furthermore, the scanning head 6 is fixedly connected to the top comb 50 close to the clamping plate 3. The cotton yarn sample combed by the top comb 50 is combed and then scanned by the top scanning head 6. When the top comb 50 moves to the end of the box cover 4 where the movement is allowed, it will not block the cotton yarn sample, so that the scanning head 6 can completely scan the straight cotton yarn sample for accurate fiber length detection.
[0036] In addition, an air jet is fixedly connected to the inside of the box cover 4, and an air inlet cavity 500 is opened on the top of several comb teeth of the top comb 50, and the air inlet of the air jet is connected to the air inlet cavity 500 of the top comb 50. An air inlet is opened on the side of the comb teeth of the top comb 50 away from the clamping plate 3, and an air outlet 40 is opened on the side of the box cover 4 away from the clamping plate 3. After the top comb 50 combs the cotton spinning sample, the fibers may hook on the comb teeth. The air jet sprays gas to the surface of the cotton spinning sample through the air inlet cavity 500 and the air port, and then discharges it through the air outlet 40, blowing the fibers on the comb teeth, so that the top comb 50 can comb the cotton spinning sample more straight.
[0037] Furthermore, several comb teeth of the top comb 50 are located at the bottom of the air inlet to open an air duct, and the angle between the air guide surface 501 formed by the air duct and the top of the comb teeth is 60°-90°. In the present embodiment, the angle between the air guide surface 501 formed by the air duct and the top of the comb teeth is selected to be 70 degrees. When the top comb 50 moves, the gas is sprayed toward the surface of the uncombed cotton yarn of the top comb 50 to avoid errors in the scanned image caused by fiber breakage and dispersion as much as possible. At the same time, the gas exerts pressure on the uncombed cotton yarn, so that the cotton yarn before combing is not easy to curl up, and the top comb 50 can more easily comb the cotton yarn straight.
[0038] Furthermore, a pressing plate 7 is fixedly connected to the bottom of the top comb 50 with the teeth facing the clamping plate 3. The bottom surface of the pressing plate 7 is parallel to the top surface of the scanning plate 2. The pressing plate 7 can compact the cotton yarn sample after being straightened by the top comb 50, and try to avoid the cotton yarn from warping after combing.
[0039] In addition, a magnetic strip is fixedly connected to the bottom of the splint 3 in the box body 1, and the splint 3 is connected to the top of the box body 1 through the magnetic strip. The bottom of the splint 3 and the top of the box body 1 clamp the cotton yarn through magnetic attraction, and the cotton yarn is difficult to shift when being combed by the top comb 50.
[0040] Furthermore, the incident direction of the laser of the scanning head 6 is at an angle of 90° to the top surface of the scanning plate 2. The laser vertically incident from the scanning head 6 to the scanning plate 2 can make the image data obtained by the image sensor of the scanning head 6 more accurate, thereby making the fiber length detected by the computer more accurate.
[0041] The implementation principle of the embodiments of this application is as follows: First, the clamping plate 3 clamps the cotton spinning sample, then the unclamped part of the cotton spinning sample is placed on the top surface of the scanning plate 2, and the box cover 4 is closed. At this time, the bottom surface of the box cover 4 abuts against the top surface of the box body 1, and the top comb 50 located at the bottom of the box cover 4 moves translationally away from the clamping plate 3 to comb the cotton spinning sample at the bottom. At the same time, the scanning head 6 on the side of the top comb 50 close to the clamping plate 3 starts to scan the straightened cotton spinning sample, and uploads the scanned image to the computer for image analysis by the computer to detect the fiber length.
[0042] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
