Description

Technical Field

[0001] This invention belongs to the field of textile yarn technology, specifically an inspection device for aramid finished products. Background Technology

[0002] Aramid finished products refer to products with a final use form and function, made from aramid fibers as the basic raw material through multiple processing steps such as spinning and weaving. Yarn is one of the most basic and important finished products of aramid. During the production and processing of yarn, it is often necessary to inspect the yarn evenness to assess whether the yarn quality meets the requirements.

[0003] Patent CN221405351U discloses a yarn evenness test analyzer with a cleaning mechanism, relating to the field of testing instrument technology. It includes a base, an operating box fixedly connected to the top of the base, a winding assembly for winding the yarn, and a cleaning assembly at the bottom of the base for collecting the limiting debris generated during testing. A drive assembly is located inside the operating box, providing power to the winding and cleaning assemblies. This patent, by incorporating the cleaning assembly, addresses the issue of yarn friction against grooves generating significant debris during testing. The debris, generated by the friction, is collected by the cleaning assembly. The cleaning assembly, along with the rotation of a second pulley, causes a turntable to rotate, which in turn drives a connecting rod. This causes a piston plate to move within a piston cylinder, creating negative pressure to collect the debris. This reduces the impact of debris residue on testing accuracy and minimizes wear on the device.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] When inspecting the evenness of yarn strands, the yarn is wound up and slides through grooves. Simultaneously, a detection plate presses down on the yarn under elastic force. When a section of the yarn with greater thickness passes through the detection plate, the plate moves a marker upwards, drawing a vertical line on a display board to indicate the yarn evenness. However, in some cases, the yarn cross-section is circular, and when the detection plate presses down on the yarn, only one side of the yarn contacts the plate. This creates a dead zone between the yarn and the plate. If the unevenness of the yarn happens to occur in this dead zone, the detection plate cannot be effectively moved, leading to missed detections and severely affecting the accuracy of the test results. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes an aramid finished product inspection device.

Multiple sliding rods are slidably connected to one side of the fixing ring 1. An adjusting ring is slidably connected to each sliding rod. A support column is fixedly connected to one side of the upper surface of the inspection table. A tension gauge is fixedly connected to one side of the upper end of the support column. The detection end of the tension gauge is fixedly connected to one side of the adjusting ring.

[0009] Preferably, a motor is fixedly connected to both sides of the upper end of the inspection table, and the output ends of the motors on both sides are fixedly connected to the middle of the unwinding roller and the winding roller, respectively.

[0010] Preferably, one end of the radial rod is rotatably connected to a connecting rod, and one end of the connecting rod is rotatably mounted on an adjusting ring.

[0011] Preferably, a spring is fitted on one side of the slide rod, with one end of the spring fixedly connected to a fixing ring and the other end fixedly connected to an adjusting ring.

[0012] Preferably, it also includes a splash-proof precision marking component;

[0013] The splash-proof precision marking assembly includes a support rod fixedly connected to one side of the upper surface of the inspection table. A housing is fixedly connected to the upper end of the support rod. Circular holes are provided on both sides of the housing, and elastic washers are fixedly connected to both end faces of the housing. The elastic washers coincide with the axis of the housing. Multiple discharge pipes are evenly distributed and fixedly penetrated along the circumferential direction of the upper edge of the housing. A support frame is fixedly connected to one side of the upper surface of the inspection table, and a pigment box is fixedly connected to one side of the upper end of the support frame.

[0014] Preferably, one end of each of the multiple discharge pipes is fixedly connected to an annular pipe, and a valve is provided at one end of each discharge pipe.

[0015] Preferably, a pump body is connected to and fixed to one side of the pigment box, and a flexible hose is connected to the discharge end of the pump body, with one end of the flexible hose connected to one side of the annular pipe.

[0016] Preferably, a second fixing ring is fixedly connected to one side of the upper surface of the inspection table. Multiple adjusting plates are evenly distributed and slidably connected along the circumference of the second fixing ring. Tension rods are fixedly connected to both ends of each adjusting plate, and the ends of the tension rods on both sides are fixedly connected to the surfaces of elastic washers on both sides.

[0017] Preferably, the outer ring of the fixed ring is rotatably sleeved with a rotating ring, and one end of the adjusting plate is rotatably provided with a transmission rod, one end of which is rotatably mounted on the rotating ring.

[0018] Preferably, a cylinder is fixedly connected to one side of the upper end of the support frame, and the piston end of the cylinder is fixedly connected to one end of the adjusting plate.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The aramid finished product inspection equipment of the present invention utilizes an enclosed protruding sensing component, which can detect yarn uniformity through the coordinated cooperation of ball bearings, detection plate one, and detection plate two. The three form a closed enclosure around the yarn. Since the yarn is fully enclosed, the value detected by the tension gauge will change regardless of which side of the enclosure is squeezed, thereby greatly reducing contact dead angles and making it less likely to miss detections, which is beneficial to improving the accuracy of the test results.

[0021] 2. The aramid finished product inspection equipment of this invention utilizes a splash-proof precision marking component. Whenever a change in the tensile strength count value is caused by defects on the yarn surface, the system stops conveying the yarn when the defect reaches the outer shell. The pump extracts pigment from the pigment box and sprays it onto the yarn surface through hoses, ring pipes, and multiple discharge pipes, thereby dyeing the defective area and creating a clear contrast between the defective area and other areas. This makes it easier for workers to spot the defective area during subsequent yarn winding, weaving, and other processing, thus avoiding missed cuts and ensuring the quality of subsequent products. Furthermore, when the yarn defect moves into the inner cavity of the outer shell, two elastic washers cooperate with the outer shell to form a sealed cavity, ensuring that the splashed pigment remains only in the cavity. This prevents pigment from splashing onto non-defective areas of the yarn, thus avoiding interference with subsequent defect location determination. Furthermore, after the yarn defect passes through the outer shell, the inner edge of the elastic washer is moved away from the yarn surface. This avoids the phenomenon that the yarn surface will continue to be stained with pigment due to friction when the yarn passes through the elastic washer because the pigment adheres to the inner edge of the elastic washer, thus preventing the marking from becoming messy. This further ensures the accuracy of the marking. Attached Figure Description

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to Figures 1-10 The present invention provides a technical solution: an aramid finished product inspection equipment, including an inspection table 1, with an unwinding roller 2 and a winding roller 4 rotatably arranged on both sides of the upper end of the inspection table 1, and an enclosed protrusion sensing component is also provided on the inspection table 1.

[0036] The enclosed protrusion sensing component includes a fixing ring 14 fixedly connected to one side of the upper surface of the inspection table 1. Multiple radial rods 13 are evenly distributed and slidably connected along the circumference of the fixing ring 14. A fixing block 15 is fixedly connected to one end of each radial rod 13. A ball bearing 16 is rotatably provided on one side of the fixing block 15. Detection plate 17 and detection plate 2 18 are fixedly connected to both sides of the fixing block 15, and adjacent detection plates 17 and 2 18 are interlocked and slidably connected. Multiple sliding rods 10 are slidably connected to one side of the fixing ring 14. An adjusting ring 9 is slidably connected to the sliding rods 10. A support column 8 is fixedly connected to one side of the upper surface of the inspection table 1. A tension gauge 5 is fixedly connected to one side of the upper end of the support column 8. The detection end of the tension gauge 5 is fixedly connected to one side of the adjusting ring 9.

[0037] In this embodiment, as Figure 1 , Figures 3-5 As shown, motor 3 is fixedly connected to both sides of the upper end of the inspection table 1, and the output ends of motor 3 on both sides are fixedly connected to the middle of the unwinding roller 2 and the winding roller 4, respectively.

[0038] A connecting rod 12 is rotatably mounted on one end of the radial rod 13, and the other end of the connecting rod 12 is rotatably mounted on the adjusting ring 9.

[0039] A spring 11 is fitted on one side of the slide rod 10. One end of the spring 11 is fixedly connected to the fixed ring 14, and the other end is fixedly connected to the adjusting ring 9.

[0040] Specifically, in existing technologies, when inspecting the evenness of yarn strands, the yarn is wound up. The wound yarn slides continuously through grooves, while a detection plate presses down on the yarn under elastic force. When a section of the yarn with greater thickness passes through the detection plate, the plate moves a marker upwards, drawing a vertical line on a display board to show the yarn evenness. However, in some cases, the yarn cross-section is circular, and when the detection plate presses down on the yarn, only one side of the yarn partially contacts the plate. This creates a dead angle between the yarn and the plate. If the unevenness of the yarn happens to occur at this dead angle, the detection plate cannot be effectively driven to move, leading to missed detections and severely affecting the accuracy of the test results.

[0041] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0042] The yarn to be inspected is wound onto the unwinding roller 2, and then one end of the yarn is pulled out and wound onto the take-up roller 4. Furthermore, by manually moving the adjusting ring 9, multiple connecting rods 12 can be rotated simultaneously. The connecting rods 12 drive multiple radial rods 13 to slide on the fixed ring 14, causing multiple balls 16 to move away from the axis of the fixed ring 14 at the same time. At this time, the yarn can pass through the center of the fixed ring 14. Moreover, since the detection end of the tension gauge 5 and its main body can undergo relative displacement, the piston end of the tension gauge 5 will also move accordingly when the adjusting ring 9 moves.

[0043] Then, the adjusting ring 9 is released, allowing it to reset under the action of the spring 11. Multiple balls 16 will then simultaneously approach and adhere to the yarn surface. As the balls 16 move simultaneously, the detection plate 17 and the detection plate 2 will slide relative to each other. Through the coordinated action of the balls 16, the detection plate 17, and the detection plate 2, an adjustable area enclosure is formed, surrounding the yarn. The inner edge of the enclosure adheres to the yarn surface. At this point, the tension detected by the tension gauge 5 is the initial value. Then, the two motors 3 are started, driving the unwinding roller 2 and the take-up roller 4 to rotate, thus conveying the yarn.

[0044] During yarn conveying, because the barrier is in contact with the circumference of the yarn, when a thicker section of the yarn moves to the barrier, it will inevitably compress one side of the barrier. Regardless of which side of the barrier is compressed, multiple radial rods 13 will slide simultaneously. This causes the connecting rod 12 to drive the adjusting ring 9 to slide on the slide rod 10, resulting in a change in the value detected by the tension gauge 5. The system records each change in value until the inspection is completed. Subsequent operators can then judge the yarn uniformity by observing the changes in the values. Thus, with the coordinated operation of the ball bearing 16, detection plate one 17, and detection plate two 18, yarn uniformity detection is achieved. These three components form a closed barrier surrounding the yarn. Because the yarn is fully enclosed circumferentially, the value detected by the tension gauge 5 will change regardless of which side of the barrier is compressed, significantly reducing contact dead zones and minimizing missed detections, thereby improving the accuracy of the test results.

[0045] In this embodiment, as Figures 6-10 As shown, it also includes a splash-proof precision marking component;

[0046] The splash-proof precision marking component includes a support rod 26 fixedly connected to one side of the upper surface of the inspection table 1. A housing 27 is fixedly connected to the upper end of the support rod 26. Circular holes are provided on both sides of the housing 27, and elastic washers 30 are fixedly connected to both end faces of the housing 27. The elastic washers 30 coincide with the axis of the housing 27. Multiple discharge pipes 28 are evenly distributed and fixedly passed through the upper circumference of the housing 27. A support frame 6 is fixedly connected to one side of the upper surface of the inspection table 1, and a pigment box 19 is fixedly connected to one side of the upper end of the support frame 6.

[0047] Multiple discharge pipes 28 are connected to a ring pipe 22 at one end, and a valve 29 is provided at one end of the discharge pipe 28.

[0048] A pump body 20 is connected and fixed to one side of the pigment box 19. A hose 21 is connected to the discharge end of the pump body 20. One end of the hose 21 is connected to one side of the annular pipe 22.

[0049] A fixing ring 23 is fixedly connected to one side of the upper surface of the inspection table 1. Multiple adjusting plates 25 are evenly distributed and slidably connected along the circumference of the fixing ring 23. Tension rods 31 are fixedly connected to both ends of the adjusting plates 25. The ends of the tension rods 31 on both sides are fixedly connected to the surfaces of the elastic washers 30 on both sides.

[0050] The outer ring of the fixed ring 23 is rotatably fitted with a rotating ring 24, and one end of the adjusting plate 25 is rotatably fitted with a transmission rod 32, with one end of the transmission rod 32 rotatably mounted on the rotating ring 24.

[0051] A cylinder 7 is fixedly connected to one side of the upper end of the support frame 6, and the piston end of the cylinder 7 is fixedly connected to one end of the adjusting plate 25.

[0052] Specifically, in the above embodiments, although the yarn evenness can be checked by the change in the value of the tension gauge 5, under normal circumstances, after inspection, the defective yarn segments need to be manually cut off or skipped by workers during subsequent processing such as winding and weaving to ensure product quality. However, when the unevenness of the yarn is not obvious, it is difficult for workers to detect, which can easily lead to missed cuts and thus affect the quality of subsequent products.

[0053] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0054] During inspection, the yarn passes through the inner cavity of the outer casing 27. Whenever a defect on the yarn surface causes a change in the tensile strength gauge 5 reading, the system stops supplying the yarn when the defect reaches the outer casing 27. The pump 20 then activates, drawing pigment from the pigment tank 19 and spraying it onto the yarn surface through hoses 21 and annular tubes 22 via multiple discharge pipes 28. This dyes the defective areas, creating a clear contrast between the defective areas and other areas. This makes it easier for workers to spot defects during subsequent processing such as winding and weaving, preventing missed cuts and ensuring product quality. Furthermore, because the discharge pipes 28 are evenly distributed around the yarn, the pigment adheres uniformly, making the markings visible from any angle. After the pigment is sprayed onto the yarn surface, valve 29 closes to prevent residual pigment from dripping onto non-defective areas.

[0055] While the above method can mark the location of yarn defects, the pigment can easily splash onto non-defective areas of the yarn during spraying, affecting subsequent defect location determination. Therefore, to avoid this problem, when the yarn defect location moves into the inner cavity of the outer casing 27, the cylinder 7 drives one of the adjusting plates 25 to move. Through the transmission of the drive rod 32 and the rotating ring 24, multiple adjusting plates 25 move simultaneously, stretching the elastic washer 30 via the tension rod 31. This adjusts the size of the central hole in the elastic washer 30, ensuring a tight fit between the hole wall and the yarn surface. At this point, the two elastic washers 30 and the outer casing 27 cooperate to form a sealed cavity, preventing the splashed pigment from affecting subsequent defect location determination due to pigment splashing onto non-defective areas of the yarn. Furthermore, after the yarn defect passes through the outer casing 27, the elastic washer 30 is stretched using the adjusting plate 25, so that the inner edge of the elastic washer 30 is far away from the yarn surface. This avoids the phenomenon that the yarn surface will continue to be stained with pigment due to friction when the yarn passes through the elastic washer 30 because the pigment adheres to the inner edge of the elastic washer 30, thus preventing the marking from becoming messy. This further ensures the accuracy of the marking.

[0056] Working principle: The yarn to be inspected is wound onto the unwinding roller 2, and then one end of the yarn is pulled out and wound onto the take-up roller 4. Furthermore, by manually adjusting the lateral adjustment ring 9, multiple connecting rods 12 can be rotated simultaneously. The connecting rods 12 drive multiple radial rods 13 to slide on the fixed ring 14, causing multiple balls 16 to move away from the axis of the fixed ring 14 at the same time. At this time, the yarn can pass through the center of the fixed ring 14. Moreover, since the detection end of the tension gauge 5 and its main body can undergo relative displacement, the piston end of the tension gauge 5 will also move accordingly when the adjustment ring 9 moves.

[0057] Then, the adjusting ring 9 is released, allowing it to reset under the action of the spring 11. Multiple balls 16 will then simultaneously approach and adhere to the yarn surface. As the balls 16 move simultaneously, the detection plate 17 and the detection plate 2 will slide relative to each other. Through the coordinated action of the balls 16, the detection plate 17, and the detection plate 2, an adjustable area enclosure is formed, surrounding the yarn. The inner edge of the enclosure adheres to the yarn surface. At this point, the tension detected by the tension gauge 5 is the initial value. Then, the two motors 3 are started, driving the unwinding roller 2 and the take-up roller 4 to rotate, thus conveying the yarn.

[0058] During yarn conveying, because the barrier is in contact with the circumference of the yarn, when a thicker section of the yarn moves to the barrier, it will inevitably compress one side of the barrier. Regardless of which side of the barrier is compressed, multiple radial rods 13 will slide simultaneously. This causes the connecting rod 12 to drive the adjusting ring 9 to slide on the slide rod 10, resulting in a change in the value detected by the tension gauge 5. The system records each change in value until the inspection is completed. Subsequent operators can then judge the yarn uniformity by observing the changes in the values. Thus, with the coordinated operation of the ball bearing 16, detection plate one 17, and detection plate two 18, yarn uniformity detection is achieved. These three components form a closed barrier surrounding the yarn. Because the yarn is fully enclosed circumferentially, the value detected by the tension gauge 5 will change regardless of which side of the barrier is compressed, significantly reducing contact dead zones and minimizing missed detections, thereby improving the accuracy of the test results.

[0059] During inspection, the yarn passes through the inner cavity of the outer casing 27. Whenever a defect on the yarn surface causes a change in the tensile strength gauge 5 reading, the system stops supplying the yarn when the defect reaches the outer casing 27. The pump 20 then activates, drawing pigment from the pigment tank 19 and spraying it onto the yarn surface through hoses 21 and annular tubes 22 via multiple discharge pipes 28. This dyes the defective areas, creating a clear contrast between the defective areas and other areas. This makes it easier for workers to spot defects during subsequent processing such as winding and weaving, preventing missed cuts and ensuring product quality. Furthermore, because the discharge pipes 28 are evenly distributed around the yarn, the pigment adheres uniformly, making the markings visible from any angle. After the pigment is sprayed onto the yarn surface, valve 29 closes to prevent residual pigment from dripping onto non-defective areas.

[0060] While the above method can mark the location of yarn defects, the pigment can easily splash onto non-defective areas of the yarn during spraying, affecting subsequent defect location determination. Therefore, to avoid this problem, when the yarn defect location moves into the inner cavity of the outer casing 27, the cylinder 7 drives one of the adjusting plates 25 to move. Through the transmission of the drive rod 32 and the rotating ring 24, multiple adjusting plates 25 move simultaneously, stretching the elastic washer 30 via the tension rod 31. This adjusts the size of the central hole in the elastic washer 30, ensuring a tight fit between the hole wall and the yarn surface. At this point, the two elastic washers 30 and the outer casing 27 cooperate to form a sealed cavity, preventing the splashed pigment from affecting subsequent defect location determination due to pigment splashing onto non-defective areas of the yarn. Furthermore, after the yarn defect passes through the outer casing 27, the elastic washer 30 is stretched using the adjusting plate 25, so that the inner edge of the elastic washer 30 is far away from the yarn surface.

This further ensures the accuracy of the marking.
