Description

Technical Field

[0001] This invention relates to the field of tensile testing technology for new material fabrics, specifically a tensile performance testing device for processing flame-retardant and antistatic fabrics made of new materials. Background Technology

[0002] During the production and processing of fabrics, their tensile properties are one of the important indicators for measuring their quality and applicability. Especially for functional fabrics such as new materials that are flame-retardant and anti-static, tensile properties not only affect their wearing comfort, but also their functional durability and service life. At present, most fabric tensile performance testing devices on the market adopt mechanical stretching methods, which fix the two ends of the fabric with clamps and apply tension, and then record the force value and deformation data during the stretching process through sensors.

[0003] Currently, most mainstream fabric tensile performance testing devices on the market employ basic mechanical stretching methods. These methods involve fixing the fabric at both ends with clamps and applying unidirectional tension, then using sensors to record the ultimate tensile force and deformation data. However, these traditional devices have significant shortcomings in testing efficiency, automation, and relevance to real-world application scenarios, making it difficult to meet the demands of modern industry for refined and efficient testing of material properties. Specifically:

[0004] Low testing efficiency and insufficient automation: Most equipment cannot achieve continuous, multi-batch automated testing processes. Each test requires manual intervention to clamp and unload samples, which seriously restricts the quality inspection efficiency of large-scale production.

[0005] The testing methods are limited and cannot comprehensively assess material performance: Traditional testing only focuses on basic parameters such as maximum tensile strength and elongation at break, while lacking effective and integrated testing methods for material performance under dynamic stress (such as repeated stretching and instantaneous release), as well as defects that are prone to occur in actual use, such as curling, snagging, and plastic deformation. This results in test results that cannot fully reflect the overall quality of the fabric.

[0006] The testing conditions are out of touch with real-world usage scenarios: Wearing clothing is a dynamic process that involves various mechanical states, including slow stretching, shape retention, and instantaneous rebound. Conventional equipment's single-stretch test mode cannot simulate these complex conditions, leading to discrepancies between test data and actual wearing experience, thus reducing the instructive value of the test results.

[0007] Therefore, developing a tensile testing device that can simulate real-world usage scenarios, achieve automated testing, possess high-precision resilience judgment capabilities, and comprehensively evaluate various fabric properties has become an urgent technical problem to be solved in this field. Summary of the Invention

[0008] The purpose of this invention is to provide a tensile performance testing device for processing new flame-retardant and antistatic fabrics, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a tensile performance testing device for processing flame-retardant and antistatic fabrics, comprising a base, a tensile assembly, and a re-tensile assembly. The tensile assembly is disposed at both ends of the top of the base, and a sliding groove is formed on the inner side of the top of the base. A winding assembly is disposed inside the sliding groove. The winding assembly includes a sliding seat, a ball bearing is disposed at the bottom outer end of the sliding seat, and a winding seat is disposed at the top outer end of the sliding seat. An opening / closing door is provided at the outer end of the winding seat, and a first motor is disposed inside the winding seat. A first electric actuator is disposed at the output end of the first motor. The winding base has a driven shaft inside, and a second electric actuator is installed at the outer end of the driven shaft. The output ends of the first and second electric actuators are equipped with locking pins, and the outer end of the locking pin is equipped with a shaft seat. The outer end of the winding base is provided with a material inlet, and the top outer end of the winding base is equipped with a third electric actuator, and the output end of the third electric actuator is equipped with a pressing seat. The two outer ends of the winding base are equipped with armature seats, and the outer end of the shaft seat is wound with fabric. The top outer end of the base is equipped with a support seat, and the bottom outer end of the support seat is equipped with a camera. The inner middle of the base is equipped with a rewinding assembly.

[0010] Furthermore, the stretching assembly includes a stretching seat, the outer end of which is provided with a fourth electric push rod, and the output end of the fourth electric push rod is provided with an electromagnet.

[0011] Furthermore, the fourth electric actuator drives the electromagnet to move, and the electromagnet is electromagnetically attracted to the armature seat.

[0012] Furthermore, the opening size of the door is greater than the length of the bearing seat, and the first electric push rod and the second electric push rod push the engaging stake to engage and fix it with the bearing seat.

[0013] Furthermore, the first motor drives the shaft seat to rotate via the first electric push rod and the locking post, and the shaft seat drives the driven shaft to rotate via the locking post and the second electric push rod.

[0014] Furthermore, the sliding seat and the winding seat are an integrated structure, and the sliding seat slides inside the sliding groove via rolling balls.

[0015] Furthermore, the retraction assembly includes a second motor, the output end of which is provided with a docking seat, and the top outer end of the docking seat is provided with a push-out seat. Pressure sensors are installed at both ends of the push-out seat, and a lifting seat is installed at the output end of the push-out seat. A suction pump is installed at the outer end of the lifting seat, and a suction pipe is connected between the suction pump and the lifting seat. A suction groove is opened at the top outer end of the lifting seat, and a fifth electric push rod is installed inside the lifting seat. A lifting head is installed at the output end of the fifth electric push rod.

[0016] Furthermore, the second motor drives the ejector seat to rotate through the docking seat, and the ejector seat drives the lifting seat to rise and fall.

[0017] Furthermore, when the sliding seat is located at the end of the sliding groove, it squeezes the pressure sensor, and the suction pump is connected to the suction groove through the suction pipe.

[0018] Furthermore, the fifth electric actuator drives the lifting head to rise and fall, and the fifth electric actuator is distributed in an array inside the lifting seat.

[0019] This invention provides a tensile property testing device for processing flame-retardant and antistatic fabrics, which has the following advantages:

[0020] 1. This invention utilizes the attraction and disconnection of an electromagnet and an armature seat to apply and release tensile force instantaneously. Since fabrics are typically made into clothing, the above test effectively simulates the stretching of clothing while worn and the natural rebound process when removed without external force. This allows the device to simulate the real-world scenario of fabric use, thereby improving the accuracy of the device's detection. Furthermore, this invention can quantitatively detect the resilience of fabrics. Traditional fabric tensile performance testing usually relies on manual observation or simple ruler measurement to determine whether the sample returns to its original position. This operation is highly subjective and inaccurate. This invention sets the point where the sliding seat presses against the pressure sensor as the initial position. When the fabric fully rebounds, causing the sliding seat to return to the initial position and press against the pressure sensor, the device determines that the rebound is successful; otherwise, it determines that the rebound performance is poor. This design transforms the difficult-to-detect resilience into a specific and quantifiable pressure signal, enabling objective and automated detection of fabric resilience. This effectively improves the detection accuracy and efficiency of the device.

[0021] 2. After the fabric of this invention rebounds, the camera at the top of the support can photograph the fabric to determine whether the fabric curls during the stretching process. During the photographing process, the suction pump works, and the suction force is transmitted to the suction groove through the suction tube. Since the suction groove is located at the top of the lifting seat, and the top of the lifting seat is in contact with the bottom of the fabric, the suction force can be transmitted to the surface of the fabric. If there is curling on the surface of the fabric, the curled fabric will become flat due to the suction force. The second motor drives the docking seat to rotate, which makes the lifting seat rotate circumferentially. This makes the suction groove smooth the entire piece of fabric. When the fabric has a more complex pattern, it is difficult for the camera to clearly determine whether the curling is present. Through the above operation, the camera can clearly determine whether the fabric has curled by comparing the before and after suction in the suction groove. This can greatly improve the detection accuracy of the equipment.

[0022] 3. This invention enables the lifting seat to move upwards by pushing out the seat, allowing it to lift the fabric. Simultaneously, one of the fifth electric push rods inside the lifting seat activates, pushing the lifting head out from within the lifting seat. Since the fabric remains fixed by the pressing seat, the lifting seat, in conjunction with the lifting head, can lift the fabric. This operation simulates the scenario where fabric is hooked and pulled when wearing clothes. Because there are five sets of lifting heads, and the lifting seat can be adjusted by the rotation of the second motor, the lifting head can move to any point on the fabric surface to lift it. This design simulates the positional uncertainty of the fabric when it is hooked and pulled. Through the above design, the detection range of the equipment can be improved while ensuring the accuracy of the equipment detection. Attached Figure Description

Detailed Implementation

[0032] Please see Figures 1 to 8This invention provides a technical solution: a tensile performance testing device for processing flame-retardant and antistatic fabrics, comprising a base 1, a tensile assembly 2, and a re-tensile assembly 8. The tensile assembly 2 is mounted at both ends of the top of the base 1. The tensile assembly 2 includes a tensile seat 201, a fourth electric push rod 202 mounted at the outer end of the tensile seat 201, and an electromagnet 203 mounted at the output end of the fourth electric push rod 202. A sliding groove 3 is formed on the inner side of the top of the base 1, and a winding assembly 4 is mounted inside the sliding groove 3. The winding assembly 4 includes a sliding seat 401, a ball bearing 402 mounted at the bottom outer end of the sliding seat 401, and a winding seat 403 mounted at the top outer end of the sliding seat 401. An opening / closing door 404 is provided at the outer end of the winding seat 403, and a first motor 405 is mounted inside the winding seat 403. A first electric actuator 406 is installed at the output end. A driven shaft 407 is installed inside the take-up seat 403, and a second electric actuator 408 is installed at the outer end of the driven shaft 407. A locking post 409 is installed at the output end of the first electric actuator 406 and the second electric actuator 408. A shaft seat 410 is installed at the outer end of the locking post 409. A material inlet 411 is provided at the outer end of the take-up seat 403, and a third electric actuator 412 is installed at the top outer end of the take-up seat 403. A pressing seat 413 is installed at the output end of the third electric actuator 412. Armature seats 414 are installed at both ends of the outer side of the take-up seat 403. Fabric 5 is wound around the outer end of the shaft seat 410. A fourth electric actuator 202 drives the electromagnet 203 to move, and the electromagnet 203 is electromagnetically attracted to the armature seat 414. The opening size of the opening / closing door 404 is larger than the length of the shaft seat 410. Furthermore, the first electric push rod 406 and the second electric push rod 408 push the locking post 409 to engage and fix it with the shaft seat 410. The first motor 405 drives the shaft seat 410 to rotate through the first electric push rod 406 and the locking post 409. The shaft seat 410 drives the driven shaft 407 to rotate through the locking post 409 and the second electric push rod 408. The sliding seat 401 and the winding seat 403 are integrated structures. The sliding seat 401 slides inside the sliding groove 3 through the rolling ball 402. A support seat 6 is installed at the top outer end of the base 1, and a camera 7 is installed at the bottom outer end of the support seat 6.

[0033] The specific operation is as follows: After the fabric 5 is produced, it can be wound onto the bearing seat 410 for storage. When the fabric is being inspected, the operator opens the opening and closing door 404 inside the take-up seat 403 on the top right of the base 1, allowing the bearing seat 410 to be placed inside the take-up seat 403. At this time, the first electric actuator 406 and the second electric actuator 408 work to drive the locking post 409 to move. The locking post 409 can then engage with the holes at both ends of the bearing seat 410, allowing the bearing seat 410 to be installed inside the take-up seat 403. After the bearing seat 410 is installed, the operator pulls the bearing seat 410. The fabric 5 wrapped around the surface allows the fabric 5 to rotate around the surface of the bearing 410 and exit through the feed port 411. The extended fabric 5 can then pass through the feed port 411. The worker can further stretch the extended fabric 5 so that it passes through the feed port 411 of the take-up seat 403 at the top left end of the base 1 and enters the take-up seat 403. The bearing 410 with empty material is placed inside the take-up seat 403 at the top left end of the base 1. After the worker fixes the extended fabric 5 to the outer end of the bearing 410, the fabric 5 is laid out.

[0034] Please see Figures 1 to 8 The base 1 has a tensioning assembly 8 installed in the middle. The tensioning assembly 8 includes a second motor 801. The output end of the second motor 801 is provided with a docking seat 802. The top outer end of the docking seat 802 is provided with a push-out seat 803. Pressure sensors 804 are installed at both ends of the push-out seat 803. Furthermore, a lifting seat 805 is installed at the output end of the ejector seat 803, a suction pump 806 is installed at the outer end of the lifting seat 805, and a suction pipe 807 is connected between the suction pump 806 and the lifting seat 805. A suction groove 808 is opened at the top outer end of the lifting seat 805, and a fifth electric push rod 809 is installed inside the lifting seat 805. A lifting head 810 is installed at the output end of the fifth electric push rod 809. The second motor 801 drives the ejector seat 803 to rotate through the dock 802, and the ejector seat 803 drives the lifting seat 805 to rise and fall. When the sliding seat 401 is located at the end of the sliding groove 3, it squeezes the pressure sensor 804. The suction pump 806 is connected to the suction groove 808 through the suction pipe 807. The fifth electric push rod 809 drives the lifting head 810 to rise and fall, and the fifth electric push rod 809 is distributed in an array inside the lifting seat 805.

[0035] The specific operation is as follows: After the fabric is laid out, the fourth electric push rod 202 at the outer end of the tension seat 201 at the top of the base 1 operates, which drives the electromagnet 203 to move. This allows the electromagnet 203 to come into contact with the armature seat 414 at the outer end of the take-up seat 403. At this time, the electromagnet 203 is energized and can attract the armature seat 414. In addition, the third electric push rod 412 inside the take-up seats 403 at both ends of the base 1 operates, which drives the pressing seat 413 to move downward. This allows the pressing seat 413 to compact and fix the fabric 5, ensuring that the tensile performance test is only performed on the fabric 5 within a unit length. After the fabric 5 is fixed, the fourth electric push rod 202 begins to reset. Because the electromagnet 203 is attracted to the armature seat 414 at this time, the fourth electric push rod 202... During the reset process, the sliding seat 401 slides inside the sliding groove 3. The sliding of the sliding seat 401 allows the take-up seat 403 to stretch and extend the fabric 5, thus enabling the equipment to detect the tensile properties of the fabric 5. After the fabric 5 has been stretched, the electromagnet 203 is de-energized, which releases the electromagnetic attraction between the electromagnet 203 and the armature seat 414. At this time, the take-up seat 403, having lost its attraction, will reset due to the resilience of the fabric 5. This allows the sliding seat 401 to slide inside the sliding groove 3 via the ball bearing 402. When the sliding seat 401 is at its initial position, its outer surface will press against the pressure sensor 804 at the outer end of the push-out seat 803. By determining whether the pressure sensor 804 senses the pressure, it can be determined whether the fabric 5 is undergoing stretching. To determine whether the fabric can spring back to its original position after stretching, this application utilizes the attraction and disconnection of the electromagnet 203 and the armature seat 414 to apply and release the tensile force instantaneously. Since fabric 5 is typically made into clothing, the above test effectively simulates the stretching of clothing while worn and the natural rebound process when removed without external force. This allows the device to simulate the real-world scenario of fabric 5 during daily use, thereby improving the accuracy of the device's testing. Furthermore, this application can quantitatively test the resilience of fabric 5. Traditional fabric tensile performance testing usually relies on manual observation or simple ruler measurement to determine whether the sample returns to its original position. This operation is highly subjective and inaccurate. This application addresses this by pressing the pressure sensor 804 against the sliding seat 401. The initial position is set at a certain point. When the fabric 5 fully rebounds, causing the sliding seat 401 to return to its initial position and press against the pressure sensor 804, the device determines that the rebound is successful. Otherwise, it is determined that the rebound performance is poor. This design transforms the difficult-to-detect rebound into a specific and quantifiable pressure signal, enabling objective and automated rebound detection of the fabric 5. This effectively improves the detection accuracy and efficiency of the equipment. After the fabric 5 rebounds, the camera 7 at the top of the support seat 6 can take a picture of the fabric 5 to determine whether the fabric 5 curls during the stretching process. During the taking picture, the suction pump 806 works, and the suction force is transmitted to the suction groove 808 through the suction pipe 807. Since the suction groove 808 is located at the top of the lifting seat 805, the suction is applied to the fabric 5.The top of the lifting seat 805 is attached to the bottom of the fabric 5, allowing the suction force to be transferred to the surface of the fabric 5. If the fabric 5 has curled edges, the suction force will smooth them out. The second motor 801 drives the docking seat 802 to rotate, causing the lifting seat 805 to rotate circumferentially. This allows the suction groove 808 to smooth the entire fabric 5. When the fabric 5 has a complex pattern, it is difficult for the camera 7 to clearly identify the curled edges. Through the above operations... Camera 7 can clearly determine whether fabric 5 has curled edges by comparing the before and after suction in the suction groove 808. This greatly improves the detection accuracy of the equipment. After the curling detection is completed, the lifting seat 805 moves upward by the operation of the push-out seat 803. This allows the lifting seat 805 to lift fabric 5. At the same time, one of the fifth electric push rods 809 inside the lifting seat 805 is activated, which drives the lifting head 810 to be pushed out from inside the lifting seat 805. Since fabric 5 is still fixed by the pressing seat 413, this allows the lifting seat 805 to... 05, in conjunction with the lifting head 810, can lift the fabric 5. This operation simulates the scenario where the fabric 5 is hooked and pulled by an object during clothing. Since there are five sets of lifting heads 810, and the lifting base 805 can be adjusted by the rotation of the second motor 801, the lifting head 810 can move to any point on the surface of the fabric 5 for lifting. This design simulates the positional uncertainty of the fabric 5 when it is hooked and pulled. Through these designs, the detection range of the equipment can be improved while ensuring the accuracy of the detection. The fabric 5 is then inspected. Then, the second electric actuator 408 moves the pressing seat 413 upward, releasing the locking of the fabric 5. At this time, the first motor 405 inside the left take-up seat 403 operates, driving the shaft seat 410 to rotate via the first electric actuator 406. During the rotation of the shaft seat 410, it can take up the fabric 5 at its outer end. While the fabric 5 is being taken up on the left shaft seat 410, the right shaft seat 410 will rotate accordingly to wind out more fabric 5. This allows the equipment to continuously test the tensile properties of the fabric 5.

[0036] In summary, this new type of tensile performance testing device for flame-retardant and antistatic fabric processing is used as follows: After the fabric 5 is produced, it can be wound onto the bearing seat 410 for storage. When the fabric is being tested, the operator opens the opening and closing door 404 inside the take-up seat 403 on the top right of the base 1, allowing the bearing seat 410 to be placed inside the take-up seat 403. At this time, the first electric push rod 406 and the second electric push rod 408 work to drive the locking post 409 to move, allowing the locking post 409 to engage with the holes at both ends of the bearing seat 410. This allows the bearing seat 410 to be placed inside the take-up seat 403. After the bearing seat 410 is placed, the operator pulls the bearing seat 410... The fabric 5 wrapped around the surface allows the fabric 5 to be wound around the surface of the bearing 410 by the rotation of the bearing 410, and the extended fabric 5 can pass through the feed port 411. The worker continues to stretch the extended fabric 5 so that the fabric 5 can pass through the feed port 411 of the take-up seat 403 at the top left end of the base 1 and enter the interior of the take-up seat 403. The bearing 410 with empty material is placed inside the take-up seat 403 at the top left end of the base 1. After the worker fixes the extended fabric 5 to the outer end of the bearing 410, the fabric 5 is laid out.

[0037] After the fabric is laid out, the fourth electric push rod 202 at the outer end of the tension seat 201 at the top of the base 1 operates, driving the electromagnet 203 to move. This allows the electromagnet 203 to come into contact with the armature seat 414 at the outer end of the take-up seat 403. At this time, the electromagnet 203 is energized and can attract the armature seat 414. In addition, the third electric push rod 412 inside the take-up seats 403 at both ends of the base 1 operates, driving the pressing seat 413 to move downward. This allows the pressing seat 413 to compact and fix the fabric 5, ensuring that the tensile performance test is only performed on the fabric 5 within a unit length. After the fabric 5 is fixed, the fourth electric push rod 202 begins to reset. Because the electromagnet 203 is attracted to the armature seat 414 at this time, the fourth electric push rod 202 can... The sliding seat 401 slides inside the sliding groove 3. The sliding of the sliding seat 401 enables the take-up seat 403 to stretch and extend the fabric 5, thereby enabling the equipment to detect the tensile properties of the fabric 5. After the fabric 5 has been extended, the electromagnet 203 is de-energized, which releases the electromagnetic attraction between the electromagnet 203 and the armature seat 414. At this time, after the take-up seat 403 loses its attraction force, it will reset due to the elasticity of the fabric 5. This allows the sliding seat 401 to slide in the sliding groove 3 via the rolling ball 402. When the sliding seat 401 is at the initial position, its outer surface will press against the pressure sensor 804 at the outer end of the push seat 803. At this time, by judging whether the pressure sensor 804 senses the pressure, it can be determined whether the fabric 5 can spring back to its original position after being stretched.

[0038] Next, after the fabric 5 rebounds, the camera 7 at the top of the support 6 can photograph the fabric 5 to determine whether the fabric 5 has curled during the stretching process. During the photographing process, the suction pump 806 operates, transmitting suction force to the suction groove 808 through the suction pipe 807. Because the suction groove 808 is located at the top of the lifting seat 805, and the top of the lifting seat 805 is in contact with the bottom of the fabric 5, the suction force can be transmitted to the surface of the fabric 5. If there is curling on the surface of the fabric 5, the suction force will be detected during the process. Under the action of suction, the rolled-up fabric 5 will become flat due to the suction force. The second motor 801 drives the docking seat 802 to rotate, which enables the lifting seat 805 to rotate in a circle. This allows the suction groove 808 to smooth the entire piece of fabric 5. When the fabric 5 is a fabric with a more complex pattern, it is difficult for the camera 7 to clearly determine the rolled-up condition. Through the above operation, the camera 7 can clearly determine whether the fabric 5 is rolled up by comparing the before and after suction by the suction groove 808. This can greatly improve the detection accuracy of the equipment.

[0039] After the edge curling inspection is completed, the lifting seat 805 moves upward by the operation of the push-out seat 803. This allows the lifting seat 805 to lift the fabric 5. At the same time, one of the fifth electric push rods 809 inside the lifting seat 805 operates, which drives the lifting head 810 to push out from inside the lifting seat 805. Since the fabric 5 is still fixed by the pressing seat 413, the lifting seat 805, in conjunction with the lifting head 810, can lift the fabric 5. This operation can simulate the scenario where the fabric 5 is hooked and pulled by an object when wearing clothes. Since there are five sets of lifting heads 810, and the lifting seat 805 can be adjusted by the rotation of the second motor 801, the lifting head 810 can move to any point on the surface of the fabric 5 to lift it. This design can simulate the positional uncertainty of the fabric 5 when it is hooked and pulled. Through the above design, the detection range of the equipment can be improved while ensuring the detection accuracy of the equipment.

[0040] Finally, after the fabric 5 has been tested, the second electric push rod 408 drives the pressing seat 413 to move upward, which releases the lock of the fabric 5. At this time, the first motor 405 in the left winding seat 403 works, which drives the shaft seat 410 to rotate through the first electric push rod 406. During the rotation of the shaft seat 410, it can wind up the fabric 5 at its outer end. When the fabric 5 is wound on the left shaft seat 410, the right shaft seat 410 will rotate accordingly to wind out more fabric 5. This allows the equipment to continuously test the tensile properties of the fabric 5.
