Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile testing technology, and in particular to a device for testing the strength of elastic yarn. Background Technology
[0002] In the modern textile industry, elastic yarn is widely used in clothing, home textiles, medical and other fields due to its good elasticity and comfortable wearing performance. From underwear to sports equipment, from home decoration to medical bandages, the performance of elastic yarn directly affects the quality of products and user experience. With the continuous growth of market demand for elastic yarn and the increasing diversification of product application scenarios, the requirements for the quality of elastic yarn are becoming more and more stringent. Among them, the strength of elastic yarn, as one of the core indicators for measuring its quality, has become a key testing parameter in the production and quality control process.
[0003] The strength testing of elastic wires largely relies on manual operation and simple tools. Testers manually stretch the elastic wires and judge their strength based on experience and intuition. This method is not only inefficient, but the test results are also greatly affected by subjective factors, making it difficult to guarantee accuracy and consistency. Even when using some basic mechanical testing equipment, staff need to wind the test wires around the corresponding positions on the testing equipment. When dealing with a large number of test wires, the winding work takes a lot of time, affecting the overall testing efficiency.
[0004] Therefore, there is an urgent need to provide a device for testing the strength of elastic wire to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for detecting the strength of elastic wire.
[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: A device for detecting the strength of elastic wire is provided, comprising a sliding frame, a fixed block fixedly connected to one side of the sliding frame, a drive motor mounted on one side of the fixed block, a lead screw fixedly connected to the output end of the drive motor, a sliding block slidably connected to the outer wall of the lead screw, a clamping mechanism provided at the top of both the fixed block and the sliding block, a detection wire installed between the two clamping mechanisms, a fixed rod fixedly connected to one side of the front end of the sliding frame, a control console fixedly connected to the front end of the fixed rod, and a screen and buttons respectively mounted on the front end of the control console.
[0007] The present invention is further configured such that: the clamping mechanism includes a fixed plate and a connecting plate respectively installed on the top of the sliding block; a plurality of fixed posts are fixedly connected between the fixed plate and the connecting plate; both ends of the plurality of fixed posts are rotatably connected to fixed screws; a plurality of fixed strips are fixedly connected to the inner sides of the fixed plate and the connecting plate; sliding strips are slidably connected to the outer walls of the plurality of fixed strips; a clamping block is installed at one end of the plurality of sliding strips; a connecting rod is fixedly connected between every two adjacent sliding strips; a sliding rod is fixedly connected to one end of the plurality of connecting rods; a motor cover is fixedly connected to one side of the fixed plate; a rotating motor is installed inside the motor cover; a rotating gear plate is fixedly connected to the output end of the rotating motor; a driven gear plate is rotatably connected to the other side of the fixed plate; a plurality of guide grooves are opened on one side of the driven gear plate; and a protective cover is fixedly connected to the other side of the fixed plate.
[0008] Using the above technical solution, the operator inserts the test wire to be tested into the clamping mechanism. The motor is then started, and its output drives the rotating gear plate to rotate. The rotating gear plate meshes with the driven gear plate, and a guide groove on the driven gear plate engages with the sliding rod. When the driven gear plate rotates, the guide groove guides the sliding rod to move along a specific trajectory. The sliding rod, through a connecting rod, drives multiple sliding strips to slide synchronously on the fixed strip. Because the cross-section of the fixed strip matches the groove on the inner side of the sliding strip, the stability of the sliding is ensured. As the sliding strip moves, the clamping block installed at one end moves accordingly, thus achieving the clamping action of the test wire. The fixed column is connected to the fixed plate and connecting plate by fixing screws at both ends, which can stabilize the entire clamping structure. The motor cover and protective cover respectively protect the rotating motor and internal transmission components, ensuring the stable and reliable operation of the clamping mechanism.
[0009] The present invention is further configured such that both ends of the detection wire are clamped between corresponding clamping blocks.
[0010] With the above technical solution, multiple clamping blocks are evenly distributed and work together on both ends of the test thread, which makes the force on both ends of the thread more uniform when it is stretched or subjected to strength testing. This avoids premature breakage of the thread due to excessive local stress caused by uneven force, which would affect the accuracy of the test results. As a result, the true strength of the elastic thread can be measured more accurately.
[0011] The present invention is further configured such that: metal strain gauges are attached to the outer walls of both ends of the detection wire, and a corresponding force sensor is installed inside the clamping mechanism at the top of the fixing block.
[0012] Through the above technical solution, the metal strain gauge can generate corresponding resistance changes as the detected wire deforms. By measuring this resistance change, the deformation of the wire under force can be accurately calculated. The force sensor can monitor the magnitude of the force applied to the detected wire by the clamping mechanism in real time. Combined with the deformation measured by the metal strain gauge, the force borne by the elastic wire under different deformations can be accurately determined. This real-time monitoring and data acquisition helps to gain a deeper understanding of the mechanical properties of the elastic wire and provides more comprehensive and accurate data support for assessing its strength.
[0013] The present invention is further configured such that: a rubber anti-slip pad is provided on the inner side of the clamping block, and the surface of the rubber anti-slip pad is provided with a plurality of anti-slip protrusions arranged in an array.
[0014] Through the above technical solution, the rubber material itself has a high static friction coefficient, which can increase the friction with the detection wire. In addition, the multiple anti-slip protrusions arranged in an array on the surface further increase the roughness of the contact surface. This allows the clamping block to grip the detection wire more firmly when clamping it, effectively preventing the wire from slipping due to force during the detection process, and ensuring the accuracy and stability of the detection.
[0015] The present invention is further configured such that the outer wall of the sliding rod slides against the inner wall of the corresponding guide groove.
[0016] Through the above technical solution, the guide groove provides a precise movement trajectory for the sliding rod, allowing it to slide only in a specific direction. This ensures that multiple sliding bars and the clamping blocks connected to them can move accurately according to the design requirements, thereby achieving uniform clamping and positioning of the detection wire and improving the accuracy and consistency of the detection.
[0017] The present invention is further configured such that the console is internally equipped with a data processing module and a storage module.
[0018] Through the above technical solution, the data processing module can quickly process and analyze real-time data transmitted from testing equipment such as force sensors and metal strain gauges, and the storage module can classify and store all data in the testing process, including force sensor data, metal strain gauge data, testing time, testing personnel and other information.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. This utility model designs a clamping mechanism that uses a rotating motor to drive a rotating gear plate. Through meshing with the driven gear plate, the rotational motion is converted into the linear motion of the sliding rod. The cooperation between the guide groove and the sliding rod ensures the accuracy of the motion trajectory, enabling multiple clamping blocks to move synchronously and stably, achieving uniform clamping of the thread. The operator only needs to insert the thread to be tested into the clamping mechanism, and the clamping block will hold the thread. The operation is simple and eliminates the complicated winding steps.
[0021] 2. This utility model uses metal strain gauges and force sensors at both ends of the detection wire to work together to capture deformation and force magnitude in real time and accurately, providing reliable data for strength assessment. Operators only need to operate the device through the control panel and record the relevant data through the screen. Attached Figure Description

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0028] Please see Figure 1 and Figure 2 A device for testing the strength of elastic wire includes a sliding frame 1, a fixing block 2 fixedly connected to one side of the interior of the sliding frame 1, a drive motor 3 installed on one side of the fixing block 2, a lead screw 4 fixedly connected to the output end of the drive motor 3, and a sliding block 5 slidably connected to the outer wall of the lead screw 4.
[0029] like Figure 3 and Figure 4 As shown, both the top of the fixed block 2 and the sliding block 5 are provided with a clamping mechanism 6. The clamping mechanism 6 includes a fixed plate 601 and a connecting plate 602 respectively installed on the top of the sliding block 5. A plurality of fixed posts 603 are fixedly connected between the fixed plate 601 and the connecting plate 602. Both ends of the plurality of fixed posts 603 are rotatably connected with fixing screws 604. A plurality of fixing strips 605 are fixedly connected to the inner sides of the fixed plate 601 and the connecting plate 602. Sliding strips 606 are slidably connected to the outer walls of the plurality of fixing strips 605. A clamping block 607 is installed at one end of the plurality of sliding strips 606. The inner side of 607 is provided with a rubber anti-slip pad. The surface of the rubber anti-slip pad has multiple arrayed anti-slip protrusions. The rubber material itself has a high static friction coefficient, which increases the friction with the detection wire 7. Combined with the arrayed anti-slip protrusions, the roughness of the contact surface is further increased. This allows the clamping block 607 to grip the detection wire 7 more firmly, effectively preventing the wire from slipping due to force during the detection process, ensuring the accuracy and stability of the detection. Metal strain gauges are attached to the outer walls of both ends of the detection wire 7 and are fixed in place. The clamping mechanism 6 at the top of block 2 is equipped with a corresponding force sensor. The metal strain gauge generates a corresponding change in resistance as the detection wire 7 deforms. By measuring this change in resistance, the deformation of the wire under force can be accurately calculated. The force sensor can monitor the magnitude of the force applied to the detection wire 7 by the clamping mechanism 6 in real time. Combined with the deformation measured by the metal strain gauge, the force borne by the elastic wire under different deformations can be accurately determined. This real-time monitoring and data acquisition helps to gain a deeper understanding of the mechanical properties of the elastic wire and provides a more comprehensive and accurate assessment of its strength. Data support is provided, and a connecting rod 608 is fixedly connected between every two adjacent sliding bars 606. One end of each of the multiple connecting rods 608 is fixedly connected to a sliding rod 609. The outer wall of the sliding rod 609 slides against the inner wall of the corresponding guide groove 614. The guide groove 614 provides a precise movement trajectory for the sliding rod 609, so that it can only slide along a specific direction. This ensures that the multiple sliding bars 606 and the clamping block 607 connected to them can move accurately according to the design requirements, thereby achieving uniform clamping and positioning of the detection wire 7 and improving the accuracy and consistency of the detection.
[0030] like Figure 3 and Figure 4As shown, a motor cover 610 is fixedly connected to one side of the fixed plate 601. A rotating motor 611 is installed inside the motor cover 610. A rotating gear plate 612 is fixedly connected to the output end of the rotating motor 611. A driven gear plate 613 is rotatably connected to the other side of the fixed plate 601. Multiple guide grooves 614 are opened on one side of the driven gear plate 613. A protective cover 615 is fixedly connected to the other side of the fixed plate 601. A detection wire 7 is installed between the two clamping mechanisms 6. Both ends of the detection wire 7 are clamped between corresponding clamping blocks 607. Multiple clamping blocks 607 are evenly distributed and act together on both ends of the detection wire 7. This makes the force on both ends of the wire more uniform when the wire is stretched or subjected to strength testing. It avoids premature breakage of the wire due to excessive local stress caused by uneven force, which would affect the accuracy of the test results. Thus, the true strength of the elastic wire can be measured more accurately.
[0031] like Figure 3 and Figure 4 As shown, the operator inserts the test wire 7 to be tested into the clamping mechanism 6, and starts it by rotating the motor 611. The output end of the motor drives the rotating gear plate 612 to rotate. The rotating gear plate 612 meshes with the driven gear plate 613 for transmission. The guide groove 614 on the driven gear plate 613 cooperates with the sliding rod 609. When the driven gear plate 613 rotates, the guide groove 614 guides the sliding rod 609 to move along a specific trajectory. The sliding rod 609 drives multiple sliding bars 606 to slide synchronously on the fixed bar 605 through the connecting rod 608. The sliding mechanism 6 moves because the cross-section of the fixed bar 605 matches the groove on the inner side of the sliding bar 606, ensuring the stability of the sliding. As the sliding bar 606 moves, the clamping block 607 installed at one end moves accordingly, thereby realizing the clamping action of the detection wire 7. The fixed column 603 is connected to the fixed plate 601 and the connecting plate 602 through the fixing screws 604 at both ends, which can stabilize the entire clamping structure. The motor cover 610 and the protective cover 615 respectively protect the rotating motor 611 and the internal transmission components, ensuring the stable and reliable operation of the clamping mechanism 6.
[0032] like Figure 1 and Figure 2 As shown, a fixed rod 8 is fixedly connected to one side of the front end of the sliding frame 1. A control console 9 is fixedly connected to the front end of the fixed rod 8. The control console 9 is equipped with a data processing module and a storage module. The data processing module can quickly process and analyze the real-time data transmitted by the force sensor, metal strain gauge and other detection devices. The storage module can classify and store all data in the detection process, including force sensor data, metal strain gauge data, detection time, detection personnel and other information. A screen 10 and a button 11 are installed on the front end of the control console 9.
[0033] In use, the operator first attaches metal strain gauges to both ends of the test wire 7, inserts the test wire 7 into the clamping mechanism 6, starts the rotating motor 611, and drives the sliding rod 609 to slide along the guide groove 614 through the meshing transmission of the rotating gear plate 612 and the driven gear plate 613. This causes the sliding bar 606 to move the clamping block 607, and the ends of the wire are firmly clamped by the rubber anti-slip pads and anti-slip protrusions. Then, the drive motor 3 is turned, the screw 4 rotates and drives the sliding block 5 to move, so that the two clamping mechanisms 6 move away from each other, stretching the test wire 7. During this process, the metal strain gauges at both ends of the wire change resistance due to deformation, and the stress sensor monitors the applied force in real time. The data is synchronously transmitted to the control console 9, where the internal data processing module quickly calculates the deformation, strength and other indicators, and the storage module classifies and saves the test data, time, personnel and other information. The screen 10 displays the test results in real time, and the operator can also control the test process through the button 11. The whole process is accurate and efficient, ensuring the reliability and scientific nature of the elastic wire strength test.
