Description

Technical Field

[0001] The present invention belongs to the technical field of fiber fabric detection, and particularly relates to a sampling detection device for high-functional fiber fabrics and a detection method thereof. Background Art

[0002] High-functional fiber fabrics refer to fabrics that are given specific high-performance through special processes or technical treatments. Such fabrics not only possess the basic characteristics of traditional fibers but also have functionality, capable of meeting specific scenarios or requirements. High-functional fiber fabrics with light-shielding performance are widely used in modern life, such as curtains and light-blocking fabrics, and are applied in places that require complete light shielding, such as baby rooms and hospital wards.

[0003] Therefore, when producing high-functional fiber fabrics with light-shielding performance, it is necessary to detect the light-shielding performance of the fabrics to avoid the phenomenon of light leakage. The light source position of traditional light-shielding performance detection devices is not convenient to adjust, resulting in relatively single detection data and being unable to meet the light-shielding performance detection of fiber fabrics under different lighting environments, making the detection data lack practicality and referenceability.

[0004] After retrieval, in the prior art, an authorized patent document with the publication number CN221803823U and the publication date of October 1, 2024, discloses a light-shielding performance detection device for a light-shielding composite fabric, including a box body. The upper end of the box body is connected to a box cover by a hinge. A fabric clamping mechanism is provided inside the box body. A detection lamp is installed at the top of the box cover. A photosensitive resistor is installed below the fabric clamping mechanism. The photosensitive resistor is installed at the top of a partition board. The partition board is horizontally installed in the middle of the box body. A resistance meter is installed at the right end outside the box body. The photosensitive resistor is electrically connected to the resistance meter. By setting the fabric clamping mechanism, when in use, the fabric is clamped on the clip of the fabric clamping mechanism, and then through the electric telescopic rod of the fabric clamping mechanism, the clip is contracted to both sides to tighten the fabric, and then the detection lamp and the photosensitive resistor are used for testing to achieve the test purpose and improve the test efficiency.

[0005] However, this device still has the following defects: Although the test purpose can be achieved and the test efficiency can be improved by testing with the detection lamp and the photosensitive resistor, the position and height of the detection lamp in this device cannot be adjusted, resulting in relatively single detection data and being unable to meet the light-shielding performance detection of fiber fabrics under different lighting environments, making the detection data lack practicality and referenceability.

[0015] A detection method for a high-functional fiber fabric sampling detection device, the detection method comprising: After passing the fiber fabric to be detected through between the sample loading platform and the sampling assembly, the fiber fabric is wound and conveyed. When sampling and detection are required, after pausing the conveying, the electric telescopic cylinder is started. After the sampling assembly moves downward to contact the fiber fabric, it drives the fiber fabric to be tensioned and move to the surface of the sample loading platform. The cutting mechanism is started to perform annular cutting on the fiber fabric. The cut sample is clamped between the sampling ring and the sample loading platform. The sample loading platform and the sampling ring drive the sample to descend into the interior of the detection box. The lighting mechanism is started to make the light emitted by the lighting mechanism pass through the sample and irradiate on the photoresistor. By monitoring the change of the resistance value of the photoresistor, the light shielding performance of the sample is detected.

[0016] The beneficial effects of the present invention are: 1. The fiber fabric is sampled by the sampling component. The sample is driven by the sample stage to move into the detection box. The positions of the detection lights are adjusted by two groups of second electric sliders and the first electric slider. The height of the detection lights from the sample is adjusted by the third electric push rod. By turning on the detection lights, the light emitted by the detection lights passes through the sample and then irradiates onto the photoresistor through the detection slot. By monitoring the change in the resistance value of the photoresistor with a resistance meter, the light-shielding performance of the sample can be detected. Moreover, the height and position of the light source can be adjusted according to the detection requirements to meet the detection of light-shielding performance data under a variety of different lighting environments, effectively improving the practicality and reference value of the detected data on the light-shielding performance of the fiber fabric.

[0017] 2. After passing the fiber fabric to be detected through between the sample stage and the sampling component, the fiber fabric is wound and conveyed. The sampling component samples the fabric sample. After sampling, the sample is driven by the sample stage to move into the detection box for the light-shielding performance detection operation of the sample. This device can automatically sample, and the collected sample is quickly detected, avoiding the complexity of manual sample collection and the inaccurate detection data caused by dust attachment or sample wear during the sample transfer process. Thus, while effectively reducing the manual workload, the accuracy of the sample detection data is improved.

[0018] 3. The first motor drives the second driving bevel gear to rotate, so that the bottom ends of several groups of L-shaped clamping plates respectively enter several groups of clamping grooves to complete the clamping of the sampling ring. By powering off the annular electromagnet, the annular electromagnet loses the attracting force on the sampling ring. The clamping mechanism is driven by the electric telescopic cylinder to move upward, and the clamping mechanism drives the sampling ring to move upward until it disengages from the sample stage. After removing the sample on the sample stage, the fiber fabric is continuously conveyed to perform the sampling and detection operations of the next group of samples, enabling the device to perform multiple sampling and detection operations on different positions of the fiber fabric continuously, effectively improving the detection efficiency while enhancing the integrity of the detection data.

[0019] 4. Two groups of first electric push rods drive the moving plate to move along the top of the detection box, thereby driving the folding light-shielding plate to stretch and perform a light-shielding operation on the detection box, so that the detection environment inside the detection box is protected from the influence of external ambient light, thereby effectively improving the accuracy of the detection data.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0024] An embodiment of the present invention provides a sampling and detection device for a high-functional fiber fabric, including a detection box 1; Exemplarily, as Figure 1-3 shown.

[0025] A sample stage 2 is arranged in the detection box 1. Support shafts 3 are fixedly connected to the four corners of the detection box 1. The tops of the four groups of support shafts 3 are fixedly connected to a top plate 4. An electric telescopic cylinder 5 is installed on the top plate 4. The output end of the electric telescopic cylinder 5 penetrates through the top plate 4 and is drivingly connected to a sampling assembly 6. The sampling assembly 6 includes a sampling ring 601. The sampling ring 601 is made of a magnetic material. A detection groove 201 is opened at the center of the sample stage 2. An annular electromagnet 202 is embedded in the top of the sample stage 2. The annular electromagnet 202 and the sampling ring 601 attract each other. An annular cutting groove 203 is opened on the sample stage 2; Specifically, after the fiber fabric to be detected passes through between the sample stage 2 and the sampling assembly 6, the fiber fabric is wound and conveyed. When the part to be detected is conveyed between the sample stage 2 and the sampling assembly 6, the conveyance is paused. The electric telescopic cylinder 5 drives the sampling assembly 6 to move downward to contact the fiber fabric, then drives the fiber fabric to be tensioned and moved to the surface of the sample stage 2. By energizing the annular electromagnet 202, the annular electromagnet 202 generates magnetism, thereby generating an attractive force on the sampling assembly 6, so that the sampling assembly 6 drives the fiber fabric to firmly adhere to the surface of the sample stage 2. The sampling assembly 6 cuts the fiber fabric, so that the sample is clamped between the sample stage 2 and the sampling ring 601, thereby completing the collection and tensioning and limiting operations of the fiber fabric, which is convenient for detecting the fiber fabric sample.

[0026] Exemplarily, as Figure 4-7 shown.

[0027] A light-shielding mechanism 7 is provided on the detection box 1. The light-shielding mechanism 7 includes a fixed plate 701 and a moving plate 705. A folding light-shielding plate 707 is provided between the fixed plate 701 and the moving plate 705. Two groups of mounting plates 702 are fixedly connected to the fixed plate 701. Two first electric push rods 703 are fixedly connected to the two groups of mounting plates 702 respectively. The output ends of the two first electric push rods 703 are fixedly connected with transmission plates 704. The two transmission plates 704 are fixedly connected to the top end of the moving plate 705. Two sliding bolts 706 are fixedly connected to the bottom end of the moving plate 705. Two sliding grooves 101 are formed on the detection box 1. The two sliding grooves 101 are respectively in movable fit with a corresponding sliding bolt 706. Specifically, when the sample stage 2 drives the fiber fabric into the detection box 1 for detection, the two first electric push rods 703 drive the moving plate 705 to move along the top of the detection box 1, so as to drive the folding light-shielding plate 707 to stretch, performing a light-shielding operation on the detection box 1, so that the detection environment inside the detection box 1 is prevented from being affected by external ambient light, thereby effectively improving the accuracy of detection data. After a group of fiber fabrics are detected, the two first electric push rods 703 drive the moving plate 705 to move in the reverse direction, so that the folding light-shielding plate 707 folds and contracts, facilitating the movement of the sample stage 2 and the sampling ring 601 to the outside of the detection box 1 for sampling operations of the next group of samples.

[0028] Two first electric sliding tables 8 are embedded and installed on the inner walls on both sides of the detection box 1. A second electric sliding table 9 is provided between the two first electric sliding tables 8. The two ends of the second electric sliding table 9 are respectively fixedly connected to the output ends of the two first electric sliding tables 8. The output end of the second electric sliding table 9 is drivingly connected with a light illumination mechanism 10. The light illumination mechanism 10 includes a slider 1001. The slider 1001 is fixedly connected to the output end of the second electric sliding table 9. A third electric push rod 1002 is fixedly connected to the bottom end of the slider 1001. The output end of the third electric push rod 1002 is drivingly connected with a detection lamp 1003. A number of second electric push rods 11 are fixedly connected to the bottom end of the inner wall of the detection box 1. The output ends of the number of second electric push rods 11 are all fixedly connected to the bottom end of the sample stage 2. A number of photosensitive resistors 12 are provided at the bottom end of the inner wall of the detection box 1. The number of photosensitive resistors 12 are all arranged directly below the detection groove 201. A resistance meter is provided outside the detection box 1. The resistance meter is electrically connected to the number of photosensitive resistors 12. Specifically, several groups of second electric push rods 11 drive the sample stage 2 to move downward, so that the sample stage 2 and the sampling ring 601 drive the fiber fabric sample to descend into the interior of the detection box 1. The positions of the lighting mechanism 10 are adjusted by two groups of second electric slides 9 and the first electric slide 8. The height of the detection lamp 1003 from the sample is adjusted by the third electric push rod 1002. By turning on the detection lamp 1003, the light emitted by the detection lamp 1003 passes through the sample and then is irradiated onto the photosensitive resistor 12 through the detection groove 201. By monitoring the change in the resistance value of the photosensitive resistor 12 with a resistance meter, the light-shielding performance of the sample can be detected.

[0029] Exemplarily, as Figure 8-10 shown.

[0030] An outer gear ring 603 is sleeved on the outer wall of the sampling ring 601. An annular groove 6011 is formed in the inner wall of the sampling ring 601. A plurality of groups of clamping grooves 6012 are formed in the inner wall of the sampling ring 601. A cutting mechanism 604 is slidably connected to the sampling ring 601; The cutting mechanism 604 includes a U-shaped bracket 6041. A clamping block 6042 is fixedly connected to one side inner wall of the U-shaped bracket 6041. The clamping block 6042 is movably attached to the annular groove 6011. A second motor 6043 is fixedly connected to the top end of the U-shaped bracket 6041. The output end of the second motor 6043 penetrates through the U-shaped bracket 6041 and is drivingly connected to a gear 6044. The gear 6044 is meshed with the outer gear ring 603. A first driving bevel gear 6045 is fixedly connected to the bottom end of the gear 6044. A first driven bevel gear 6046 is meshed with the first driving bevel gear 6045. A rotating shaft 6047 is fixedly connected to the center of the first driven bevel gear 6046. The rotating shaft 6047 penetrates through the U-shaped bracket 6041 and is fixedly connected to a cutting disc 6048. The cutting disc 6048 is movably attached to the annular cutting groove 203; Specifically, the second motor 6043 drives the gear 6044 to rotate. Due to the meshing relationship between the gear 6044 and the outer gear ring 603, when the gear 6044 rotates, it makes a circular movement around the central axis of the outer gear ring 603. At the same time, the gear 6044 drives the first driving bevel gear 6045 to rotate, so that the first driven bevel gear 6046 drives the cutting disc 6048 to rotate synchronously, performing a circular cutting operation on the fiber fabric, thereby completing the sampling of the fiber fabric.

[0031] The sampling assembly 6 further includes a clamping mechanism 602. The clamping mechanism 602 is movably clamped with the sampling ring 601. The top end of the clamping mechanism 602 is fixedly connected to the output end of the electric telescopic cylinder 5; The clamping mechanism 602 includes a clamping disc 6021. A first motor 6022 is installed at the top end of the clamping disc 6021. A protective box is arranged outside the first motor 6022. The top end of the protective box is in transmission connection with the output end of the electric telescopic cylinder 5. A transmission groove 6024 is formed at the center of the bottom end of the clamping disc 6021. The top end inner wall of the transmission groove 6024 is rotatably connected with a second driving bevel gear 6025. A number of second driven bevel gears 6026 are meshed and connected to the second driving bevel gear 6025. A number of screw rod grooves 6027 are formed at the bottom end of the clamping disc 6021. The number of screw rod grooves 6027 are arranged in a circular array centered on the central axis of the clamping disc 6021. A screw rod 6028 is rotatably connected in each of the number of screw rod grooves 6027. One ends of the number of screw rods 6028 are respectively fixedly connected to the centers of the number of second driven bevel gears 6026. An internally threaded block 6029 is threadedly connected to each of the number of screw rods 6028. An L-shaped clamping plate 6023 is fixedly connected to the bottom end of each of the number of internally threaded blocks 6029. The bottom ends of the number of L-shaped clamping plates 6023 are respectively movably clamped in a number of clamping grooves 6012; Specifically, the first motor 6022 drives the second driving bevel gear 6025 to rotate, so that the number of second driven bevel gears 6026 drive the number of screw rods 6028 to rotate synchronously, so that the number of internally threaded blocks 6029 drive the number of L-shaped clamping plates 6023 to move away from the center of the clamping disc 6021, so that the bottom ends of the number of L-shaped clamping plates 6023 respectively enter the number of clamping grooves 6012, completing the clamping of the sampling ring 601. The clamping mechanism 602 drives the sampling ring 601 to move downward until the sampling ring 601 drives the fiber fabric to fit on the surface of the sample stage 2. After the sample is cut by the cutting mechanism 604, the first motor 6022 drives the second driving bevel gear 6025 to rotate in the reverse direction, so that the number of second driven bevel gears 6026 drive the number of screw rods 6028 to rotate synchronously in the reverse direction, so that the number of internally threaded blocks 6029 drive the number of L-shaped clamping plates 6023 to move toward the center of the clamping disc 6021, so that the bottom ends of the number of L-shaped clamping plates 6023 are respectively disengaged from the number of clamping grooves 6012, so that the sampling ring 601 is disengaged from the clamping mechanism 602. The sampling ring 601 drives the sample to firmly fit on the surface of the sample stage 2 and moves into the interior of the detection box 1 along with the sample stage 2 for sample detection.

[0032] The working principle of a high-functional fiber fabric sampling and detection device proposed by the present invention is as follows: After passing the fiber fabric to be detected through between the sample stage 2 and the sampling assembly 6, the fiber fabric is wound and conveyed. When the part to be detected is conveyed between the sample stage 2 and the sampling assembly 6, the conveying is paused. The sampling assembly 6 is driven by the electric telescopic cylinder 5 to move downward to contact the fiber fabric, and then drives the fiber fabric to be tightened and move to the surface of the sample stage 2. By energizing the annular electromagnet 202, the annular electromagnet 202 generates magnetism to exert an attractive force on the sampling ring 601, and the sampling ring 601 drives the fiber fabric to be tightened and fit on the surface of the sample stage 2.

[0033] The second motor 6043 drives the gear 6044 to rotate. Due to the meshing relationship between the gear 6044 and the external tooth ring 603, while the gear 6044 rotates, it makes a circular movement around the central axis of the external tooth ring 603. At the same time, the gear 6044 drives the first driving bevel gear 6045 to rotate, so that the first driven bevel gear 6046 drives the cutting disc 6048 to rotate synchronously, performing a circular cutting operation on the fiber fabric, thereby completing the sampling of the fiber fabric. The first motor 6022 drives the second driving bevel gear 6025 to rotate in the reverse direction, so that several groups of second driven bevel gears 6026 drive several groups of lead screws 6028 to rotate synchronously in the reverse direction. As a result, several groups of internal thread blocks 6029 drive several groups of L-shaped clamping plates 6023 to move towards the center of the clamping disc 6021, so that the bottoms of several groups of L-shaped clamping plates 6023 are respectively disengaged from several groups of clamping grooves 6012, so that the sampling ring 601 is disengaged from the clamping mechanism 602. The sampling ring 601 drives the sample to firmly fit on the surface of the sample stage 2. The sample stage 2 is driven by several groups of second electric push rods 11 to move downward, so that the sample stage 2 and the sampling ring 601 drive the fiber fabric sample to descend into the interior of the detection box 1.

[0034] Two groups of first electric push rods 703 drive the moving plate 705 to move on the top of the detection box 1, thereby driving the folding light-shielding plate 707 to stretch, performing a light-shielding operation on the detection box 1, so that the detection environment inside the detection box 1 is prevented from being affected by the external ambient light, thereby effectively improving the accuracy of the detection data.

[0035] The positions of the detection lamps 1003 are adjusted by two groups of second electric slides 9 and the first electric slide 8. The height of the detection lamps 1003 from the sample is adjusted by the third electric push rod 1002. By turning on the detection lamps 1003, the light emitted by the detection lamps 1003 passes through the sample and then is irradiated onto the photoresistor 12 through the detection groove 201. By monitoring the change of the resistance value of the photoresistor 12 with the ohmmeter, the light-shielding performance of the sample can be detected, and the height and position of the light source can be adjusted according to the detection requirements to meet the detection of the light-shielding performance data under a variety of different light environments.

[0036] After completing the detection of a set of fiber fabrics, the moving plate 705 is driven to move in the reverse direction by two groups of first electric push rods 703, so that the folding light-shielding plate 707 is folded and contracted. The sample stage 2 is driven to move upward by several groups of second electric push rods 11, so that the sample stage 2 and the sampling ring 601 drive the sample to rise to the outside of the detection box 1. The second driving bevel gear 6025 is driven to rotate by the first motor 6022, so that the bottom ends of several groups of L-shaped clamping plates 6023 respectively enter several groups of clamping grooves 6012 to complete the clamping of the sampling ring 601. By cutting off the power supply of the annular electromagnet 202, the annular electromagnet 202 loses the attracting force on the sampling ring 601. The clamping mechanism 602 is driven to move upward by the electric telescopic cylinder 5, so that the clamping mechanism 602 drives the sampling ring 601 to move upward until it is separated from the sample stage 2. After removing the sample on the sample stage 2, the fiber fabric is continuously conveyed to perform the sampling and detection operations of the next group of samples.

[0037] On the basis of the above sampling and detection device for high-functional fiber fabrics, an embodiment of the present invention further proposes a detection method for the sampling and detection device. Exemplarily, the detection method includes: After passing the fiber fabric to be detected through between the sample stage and the sampling assembly, the fiber fabric is wound and conveyed. When sampling and detection are required, after pausing the conveyance, the electric telescopic cylinder is started. After the sampling assembly moves downward to contact the fiber fabric, it drives the fiber fabric to be tensioned and move to the surface of the sample stage. The annular electromagnet is energized, and the annular electromagnet generates an attracting force on the sampling ring. The sampling ring drives the fiber fabric to be tensioned and attached to the surface of the sample stage. The second motor is started, and the cutting disc rotates to perform annular cutting on the fiber fabric. The cut sample is clamped between the sampling ring and the sample stage. The first motor is started, and several groups of L-shaped clamping plates move inward synchronously and are respectively separated from several groups of clamping grooves, so that the clamping mechanism is separated from the sampling ring. Several groups of second electric push rods are started to drive the sample stage to move downward, so that the sample stage and the sampling ring drive the sample to descend into the detection box. Two groups of first electric push rods are started to drive the moving plate to move on the top of the detection box, so as to drive the folding light-shielding plate to stretch and perform a light-shielding operation on the detection box. The detection lamp is started, so that the light emitted by the detection lamp passes through the sample and is irradiated onto the photoresistor through the detection groove. The change in the resistance value of the photoresistor is monitored by the resistance meter to detect the light-shielding performance of the sample. When the detection of a set of fiber fabrics is completed, two groups of first electric push rods are started to drive the moving plate to move in the reverse direction, so that the folding light-shielding plate is folded and contracted. Turn on several groups of second electric push rods to drive the sample stage to move upward, so that the sample stage and the sampling ring drive the sample to rise outside the detection box; Turn on the first motor, and several groups of L-shaped clamping plates move outward synchronously and respectively enter several groups of clamping grooves, so that the clamping mechanism is clamped with the sampling ring; Cut off the power supply of the annular electromagnet, the annular electromagnet loses the attractive force on the sampling ring, turn on the electric telescopic cylinder to drive the clamping mechanism and the sampling ring to move upward to separate them from the sample stage; After removing the sample on the sample stage, continue to convey the fiber fabric to perform the collection and detection operations of the next group of samples.
