Description

Technical Field

[0001] This utility model relates to the technical field of textile material testing equipment, specifically a textile material tensile strength testing device. Background Technology

[0002] Textile materials refer to fibers and fiber products, specifically fibers, yarns, fabrics and their composites. In modern textiles, the research and development of new textile materials, especially the development and use of nanofibers, has broken through the traditional concept of textile materials. Textile materials have become an important part of soft matter materials. Taking "shape" and its composite forms as the main research subject is one of the basic characteristics of textile materials.

[0003] The tensile strength of textile materials directly affects their quality and the quality of finished products. Therefore, textile materials need to be subjected to tensile tests after production or before use to avoid substandard products that could affect profitability. However, existing textile tensile testing devices on the market can only perform linear tensile testing, which is a single function and cannot compare test values. Furthermore, existing clamping devices for textile materials still exhibit localized loosening after clamping, and when textile materials are subjected to elastic tension, they will tighten, which can easily pose a safety hazard to testing personnel. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the tensile strength of textile materials, which can perform tensile testing in different ways, improve the accuracy of the test, ensure the stability of the textile material clamping parts, and has a protective function to improve the safety of the testing personnel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a textile material tensile strength testing device, comprising a base, a testing mechanism disposed on the base, and a control display for controlling the testing mechanism. The testing mechanism includes a bracket, a first clamping member, a second clamping member, a tensile sensor, a telescopic device, and a motor. The brackets are vertically and symmetrically arranged in groups on both sides of the top of the base. The first clamping member and the second clamping member have the same structure and function, and are disposed between the two brackets. One end of the tensile sensor is disposed on the side of the first clamping member away from the second clamping member. The telescopic device and the motor are respectively disposed on opposite sides of the two brackets. The output end of the telescopic device is disposed on the other side of the tensile sensor, and the output shaft of the motor is disposed on the second clamping member. The control display is electrically connected to the tensile sensor, the telescopic device, and the motor.

[0006] To improve the gripping stability of textile materials, in a preferred embodiment of the textile material tensile strength testing device of this utility model, the first clamping component includes a U-shaped connecting seat and a rectangular frame-shaped clamping seat. One open end of the connecting seat is located on the clamping seat. A fixed clamping plate is horizontally fixedly connected to the center of the clamping seat. Movable clamping plates are symmetrically arranged on the upper and lower sides of the fixed clamping plate, and the two sides of the movable clamping plates are in contact with the inner wall of the clamping seat. Threaded rods with handles at one end are symmetrically arranged on the upper and lower sides of the clamping seat. Threaded holes adapted to the threaded rods are opened at both ends of the clamping seat. One end of the threaded rod extends into the clamping seat through the threaded hole and is rotatably connected to the movable clamping plate.

[0007] One end of the tension sensor is fixedly connected to the connecting seat on the first clamping member, and the output shaft of the motor is fixedly connected to the connecting seat on the second clamping member.

[0008] To prevent the textile material from loosening and increasing resistance, the preferred embodiment of the textile material tensile strength testing device of this utility model has corrugated teeth on both sides of the fixed clamp and the movable clamp.

[0009] To improve the stability of the first clamping member, in a preferred embodiment of the textile material tensile strength testing device of this utility model, the first clamping member and the second clamping member are horizontally symmetrically provided with guide rods fixed to two supports on their upper and lower sides.

The input end of the vacuum cleaner is connected to the dust suction cover through a pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model clamps and fixes both ends of a textile material to a first clamping member and a second clamping member, respectively. By activating the telescopic device, the first clamping member is pulled to move, and the tensile strength value of the textile material can be detected by a tension sensor.

[0019] Please see Figures 1 to 3 A tensile strength testing device for textile materials includes a base 1, a testing mechanism mounted on the base 1, and a control display 2 for controlling the testing mechanism. The testing mechanism includes a support 3, a first clamping member 4, a second clamping member 5, a tensile sensor 6, a telescopic device 7, and a motor 8. The support 3 is vertically and symmetrically arranged in groups on both sides of the top of the base 1. The first clamping member 4 and the second clamping member 5 have the same structure and function, and are located between the two supports 3. One end of the tensile sensor 6 is located on the side of the first clamping member 4 away from the second clamping member 5. The telescopic device 7 and the motor 8 are respectively located on opposite sides of the two supports 3. The output end of the telescopic device 7 is located on the other side of the tensile sensor 6, and the output shaft of the motor 8 is located on the second clamping member 5. The control display 2 is electrically connected to the tensile sensor 6, the telescopic device 7, and the motor 8.

[0020] This embodiment demonstrates the tensile strength testing of a pair of textile materials:

[0021] The two ends of the textile material are clamped and fixed to the first clamping member 4 and the second clamping member 5 respectively. After fixing, the telescopic device 7 is activated, so that the tension sensor 6 pulls the first clamping member 4 to move away from the second clamping member 5. When pulling, the tension sensor 6 can easily detect the tensile strength value of the textile material. The change of the tensile strength value of the textile material during stretching can be viewed intuitively by controlling the display 2.

[0022] This second example demonstrates the tensile strength testing of textile materials.

[0023] The two ends of the textile material are clamped and fixed to the first clamping member 4 and the second clamping member 5 respectively. After fixing, the textile material is stretched flat. The first clamping member 4 remains stationary. The motor 8 is started, causing the second clamping member 5 to rotate. When the second clamping member 5 rotates, it drives the textile material to rotate synchronously. As the second clamping member 5 rotates, the textile material will be stretched by elastic force and become taut. This allows the tension sensor 6 to detect the tensile strength of the textile material. By comparing and analyzing the data obtained from two different detection methods, the tensile strength value of the textile material can be accurately obtained, improving the practicality of the detection device.

[0024] The telescopic device 7 of this utility model is an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod; the motor 8 is a motor with a self-locking function.

[0025] As a technical optimization of this utility model, the first clamping member 4 includes a U-shaped connecting seat 9 and a rectangular frame-shaped clamping seat 10. One open end of the connecting seat 9 is provided on the clamping seat 10. A fixed clamping plate 11 is horizontally provided at the center of the clamping seat 10 and is fixedly connected thereto. Movable clamping plates 12 are symmetrically provided on the upper and lower sides of the fixed clamping plate 11, and the two sides of the movable clamping plates 12 are in contact with the inner wall of the clamping seat 10. Threaded rods 13 with handles at one end are symmetrically provided on the upper and lower sides of the clamping seat 10. Threaded holes 14 that are adapted to the threaded rods 13 are opened at both the upper and lower ends of the clamping seat 10. One end of the threaded rod 13 extends into the clamping seat 10 through the threaded hole 14 and is rotatably connected to the movable clamping plate 12.

[0026] One end of the tension sensor 6 is fixedly connected to the connecting seat 9 on the first clamping member 4, and the output shaft of the motor 8 is fixedly connected to the connecting seat 9 on the second clamping member 5.

[0027] In this embodiment, the two ends of the textile material pass through the upper and lower sides of the fixed clamping plate 11. By rotating the handle at one end of the threaded rod 13, the movable clamping plate 12 moves toward the fixed clamping plate 11, making it easy to clamp and fix the textile material between the fixed clamping plate 11 and the movable clamping plate 12. The double clamping and fixing by the two movable clamping plates 12 and the one fixed clamping plate 11 can improve the firmness of the clamping of the textile material, ensure that it is clamped in place, avoid loosening, improve the accuracy and efficiency of the test, and prevent the textile material from breaking free and causing safety hazards to the test personnel.

[0028] As a technical optimization of this utility model, corrugated teeth 15 are provided on both sides of the fixed clamping plate 11 and the movable clamping plate 12.

[0029] In this embodiment, the corrugated teeth 15 further enhance the resistance of the fixed clamping plate 11 and the movable clamping plate 12 to clamping the textile material, improve the clamping firmness, and ensure that the textile material is clamped in place, thus avoiding safety hazards to the testing personnel.

[0030] As a technical optimization of this utility model, the first clamping member 4 and the second clamping member 5 are horizontally symmetrically provided with guide rods 16 fixedly connected to the two brackets 3 on their upper and lower sides. Guide sleeves 17 are slidably provided on the two guide rods 16, and connecting rods 18 are vertically provided on the guide sleeves 17. The other ends of the two connecting rods 18 are respectively fixedly connected to the connecting seats 9 on the first clamping member 4.

[0031] In this embodiment, when the first clamping member 4 moves, the guide sleeve 17 on the connecting rod 18 is restricted by the guide rod 16, which further improves the stability of the movement of the first clamping member 4.

[0032] As a technical optimization of this utility model, the base 1 is provided with a transparent protective cover 19 on the top, the protective cover 19 is provided with a rotatable door 20, the detection mechanism is located inside the protective cover 19, and the control display 2 is located on the outer wall of the protective cover 19.

[0033] In this embodiment: the textile material is subjected to tensile testing to determine its strength; the protective cover 19 provides protection, making it easy and safe to perform tensile testing on the textile material and avoiding safety hazards to the testing personnel.

[0034] As a technical optimization of this utility model, a dust suction hood 21 is provided at the top inside the protective cover 19, and a vacuum cleaner 22 is provided at the top of the protective cover 19. The input end of the vacuum cleaner 22 is connected to the dust suction hood 21 through a pipe.

[0035] In this embodiment: when the testing agency performs tensile testing on the textile material, the lint on the textile material will fall into the dust collection hood 21. By starting the vacuum cleaner 22, suction is generated inside the dust collection hood 21, making it easier to clean the inside of the dust collection hood 21.

[0036] Working principle and usage process of this utility model:

[0037] The two ends of the textile material are clamped and fixed to the first clamping member 4 and the second clamping member 5 respectively. After fixing, the telescopic device 7 is activated, causing the tension sensor 6 to pull the first clamping member 4 away from the second clamping member 5. During the pulling, the tension sensor 6 can easily detect the tensile strength value of the textile material. The change in the tensile strength value of the textile material during stretching can be visually viewed through the control display 2. After detection, the same amount of the same textile material is selected, and the two ends of the textile material are clamped and fixed to the first clamping member 4 and the second clamping member 5 respectively. After fixing, the textile material is stretched flat, and the motor 8 is activated, causing the second clamping member 5 to rotate. When the second clamping member 5 rotates, it synchronously drives the textile material to rotate. As the second clamping member 5 rotates, the textile material will be subjected to elastic tension and become taut, allowing the tension sensor 6 to detect the tensile strength of the textile material. By comparing and analyzing the data obtained from the two detection methods, the tensile strength value of the textile material can be accurately obtained, improving the practicality of the detection device.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
