Description

Technical Field

[0001] The present invention belongs to the technical field of polyester blended fiber yarns, and specifically relates to a device for detecting the width of polyester blended fiber yarns. Background Art

[0002] In the field of the textile industry, polyester blended fiber yarns are widely used in sub - fields such as clothing and home textiles due to their excellent wear resistance, wrinkle resistance, and economic cost advantages. The width of the yarn is a core indicator for measuring its quality, directly affecting the stability of subsequent textile processing (such as weaving uniformity), the texture and functionality of the finished product. However, the current detection technologies for the width of polyester blended fiber yarns have significant defects: traditional detections mostly adopt mechanical contact measurements, such as manually measuring with a caliper or using a mechanical probe to squeeze the yarn to obtain width data. Although this method is simple to operate, it will cause physical damage to the surface of the yarn. Especially for high - count and high - density yarns with fine surface treatment, it is easy to damage the fiber structure or surface coating, resulting in a decline in the quality of the yarn and unable to meet the production requirements of high - end textile products. Some non - contact detection technologies (such as ordinary laser ranging and ultrasonic detection) avoid contact damage, but there are problems with limited detection accuracy. For example, laser ranging is easily affected by the reflective characteristics of the yarn surface and environmental light fluctuations, resulting in data deviation; ultrasonic detection is sensitive to changes in the internal structure of the yarn and cannot accurately reflect the appearance width. In addition, when dealing with the complex blended materials of polyester blended fiber yarns (such as differences in surface characteristics caused by different fiber ratios), these technologies have poor adaptability and are difficult to ensure the stability of the detection results. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a device for detecting the width of polyester blended fiber yarns that can overcome or at least partially solve the above problems.

[0004] To solve the above technical problems, the basic concept of the technical solution adopted in the present invention is as follows: A polyester blended fiber yarn width detection device includes a frame, and further includes: an adjustment support frame fixedly connected to the frame, a cover plate is arranged on the adjustment support frame, a tail support frame is fixedly connected to the frame, and an optical detection box is fixedly connected to the adjustment support frame and the tail support frame; a first industrial camera and a second industrial camera are symmetrically and fixedly connected to the optical detection box, and a backlight source is arranged on the back of the first industrial camera in the optical detection box for providing uniform background light for the camera; the lenses of the first industrial camera and the second industrial camera are telecentric lenses, and the telecentric lenses are used to keep a constant ratio with the actual yarn when taking yarn images. After the yarn enters the optical detection box, the backlight source provides uniform background light for the first industrial camera and the second industrial camera. The two cameras synchronously take yarn images through the telecentric lenses. The telecentric lenses eliminate the image distortion caused by the change of object distance, ensure that the ratio of the yarn size in the captured image to the actual size is constant, and the dual cameras collect yarn contour images from symmetrical angles, providing multi-dimensional information for subsequent data processing and improving the detection accuracy.

[0005] Further, a shock pad is fixedly connected to the frame for stabilizing the frame.

[0006] Further, a driving motor is fixedly connected to the frame, an input shaft is fixedly connected to the driving motor, a first pulley is rotatably connected to the input shaft, and a first belt shaft is rotatably connected to the first pulley.

[0007] Further, an adjustment screw is threadedly connected to the cover plate, an adjustment nut is threadedly connected to the adjustment screw, a return spring is sleeved on the adjustment screw, a sliding block is fixedly connected to the adjustment screw, and the sliding block is slidably connected to the adjustment support frame. After the driving motor is started, the first pulley is driven to rotate through the input shaft, and through the transmission system composed of the first belt shaft, the second belt shaft, the second pulley and the output shaft, the adjustment guide yarn wheel is driven to rotate to provide conveying power for the yarn. If it is necessary to adapt to different yarn specifications, the adjustment screw and the adjustment nut can be rotated, and the return spring assists the sliding block to slide on the adjustment support frame to adjust the position of the adjustment guide yarn wheel and optimize the yarn conveying path.

[0008] Further, an adjustment guide yarn wheel is rotatably connected to the sliding block, a fixed guide yarn wheel is rotatably connected to the adjustment support frame, the adjustment guide yarn wheel and the fixed guide yarn wheel correspond to each other, and cleaning wheels are symmetrically and rotatably connected to the adjustment support frame. During the conveying process of the yarn, through the cooperation and guidance of the adjustment guide yarn wheel and the fixed guide yarn wheel, and at the same time, the cleaning wheels symmetrically arranged on the adjustment support frame clean the surface of the yarn to remove impurities and avoid the interference of impurities on the subsequent detection accuracy.

[0009] Further, the peripheries of the adjustment guide yarn wheel and the fixed guide yarn wheel are wrapped with rubber.

[0010] Further, an adjusting yarn guide wheel is fixedly connected to the first belt shaft. One end of the adjusting yarn guide wheel away from the first belt shaft is fixedly connected to a second belt shaft. A second belt pulley is rotatably connected to the second belt shaft, and an output shaft is rotatably connected to the second belt pulley.

[0011] Further, a first balance wheel and a second balance wheel are rotatably connected to the tail support frame. The first balance wheel and the second balance wheel correspond to each other. After the yarn is detected, it is guided and tension balanced by the first balance wheel and the second balance wheel on the tail support frame to ensure stable output of the yarn and avoid winding or deviation of the yarn due to uneven tension after detection.

[0012] Further, a fixed bracket is fixedly connected to the frame. A central shaft is rotatably connected to the fixed bracket. A rotating shaft is rotatably connected to the central shaft. A yarn group is fixedly connected to the rotating shaft. A clamping block is inserted into the central shaft. A rotating handle is threadedly connected to the clamping block. The rotating handle drives the axial displacement of the clamping block through rotation to clamp the central shaft.

[0013] Further, a connecting plate is fixedly connected to the fixed bracket. A limiting frame is rotatably connected to the connecting plate. The limiting frame is distributed on the connecting plate in a V shape. The polyester blended fiber yarn is installed on the central shaft of the fixed bracket. By rotating the rotating handle to drive the axial displacement of the clamping block, the central shaft is clamped to ensure stable fixation of the yarn group. The V-shaped limiting frame on the connecting plate limits the starting position of the yarn and guides the yarn to be conveyed along a preset path.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: Through the first industrial camera and the second industrial camera symmetrically arranged on the optical detection box, in cooperation with the backlight source and the telecentric lens, the non-contact detection is realized. The telecentric lens eliminates image distortion, ensures that the ratio of the captured image to the actual yarn size is constant, and combines the symmetric shooting of the two cameras to improve the width detection accuracy. The non-contact method avoids physical damage to the yarn surface caused by traditional contact measurement and guarantees the yarn quality.

[0015] The adjusting screw, adjusting nut, return spring and sliding block on the adjusting support frame constitute an adjusting structure, which can flexibly adjust the position of the adjusting yarn guide wheel to adapt to polyester blended fiber yarns of different thicknesses. The clamping block on the fixed bracket and the rotating handle cooperate to firmly clamp yarn groups of different specifications, meeting diverse detection requirements.

[0016] The cleaning wheels symmetrically arranged on the adjusting support frame clean the surface of the yarn during the yarn conveying process, removing foreign matters such as impurities and fluff, avoiding interference of impurities in the optical detection link, ensuring that the images collected by the camera are clear and interference-free, and improving the reliability of the detection results.

[0017] The drive motor is equipped with transmission structures such as a first pulley and a second pulley to provide stable power output and ensure the uniform and smooth conveyance of the yarn; the shock pads stabilize the frame, reduce the interference of external vibrations on the detection device, and ensure the continuity and stability of the detection process.

[0018] The first balance wheel and the second balance wheel on the tail support frame guide and balance the tension of the yarn after the detection is completed, preventing the yarn from being entangled or deflected due to uneven tension, and providing good conditions for subsequent winding or processing processes.
