Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0061] Embodiment 1:

[0062] As Figures 1-4 shown, this embodiment provides an elastic detection device for textile fabrics, including:

[0063] Two chassis 1, which are symmetrically distributed.

[0064] Positioning holes 2 are opened on the front and rear sides of the chassis 1.

[0065] A support platform 3 is arranged on the top of the chassis 1 for placing the fabric.

[0066] A detection mechanism 4 is arranged between the bottoms of the two support platforms 3 for detecting the elasticity of the fabric.

[0067] This detection mechanism 4 includes:

[0068] A support frame 41 is arranged at the bottom of the support platform 3.

[0069] A mounting frame 42 is arranged on the support frame 41.

[0070] A power unit 43 is arranged on the mounting frame 42.

[0071] A detection plate 44 is arranged on the top of the power unit 43 and is located between the bottoms of the two support platforms 3.

[0072] Pressure sensors 45 are arranged on the detection plate 44. There are multiple pressure sensors 45, which are evenly spaced on the detection plate 44.

[0073] A data processing unit 46, electrically connected to the pressure sensor 45, is configured to receive the fabric elasticity numerical information detected by the pressure sensor 45 and process the elasticity numerical information.

[0074] A display unit 47 is configured to display the numerical information received by the data processing unit 46.

[0075] In this technical solution, the positioning holes 2 are used to ensure that the entire device is stably installed at the designated position during use. A support platform 3 is provided on the top of the two chassis 1 for placing the textile fabric to be tested. The support platform 3 ensures that the fabric can be unfolded flatly and correctly for subsequent elasticity detection. The detection mechanism 4 is arranged between the bottoms of the two support platforms 3 and is used to measure and evaluate the elastic characteristics of the fabric. The detection mechanism 4 consists of: a support frame 41 installed at the bottom of the support platform 3 to provide structural support for the device; a mounting frame 42 located on the support frame 41 to support and connect the power unit 43; the power unit 43 is installed on the mounting frame 42 and is used to drive the actions or operations during the detection process; a detection plate 44 is arranged on the top of the power unit 43 and is located in the space between the two support platforms 3. The detection plate 44 moves up and down or applies pressure according to the operation of the power unit 43. A plurality of pressure sensors 45 are evenly distributed on the detection plate 44. The pressure sensors are used to detect the force or pressure applied to the fabric and transmit this data to the data processing unit 46. After receiving the information, the data processing unit 46 displays it through the display unit 47.

[0076] Working process: The operator places the textile fabric to be tested on the support platform 3, ensures that the fabric is fully unfolded and within the detection area, and then the operator starts the power unit 43 in the device. The movement of the detection plate 44 is controlled through the power unit 43. The detection plate 44 applies a force or pressure to the fabric, causing the detection plate 44 to squeeze the fabric, resulting in stretching and deformation of the fabric. The pressure distribution and elastic feedback on the fabric are measured through the pressure sensor 45. The data collected by the pressure sensors 45 on the detection plate 44 are transmitted to the data processing unit 46. The data processing unit 46 analyzes parameters such as the elastic characteristics and elongation rate of the fabric. Finally, the data processing unit 46 displays the detection results through the display unit 47. In this way, the elastic characteristics of the textile fabric are effectively measured and evaluated, providing important data support for quality control and production processes in the textile industry. By detecting, it is possible to understand whether the fabric meets the requirements, thus facilitating subsequent improvement and processing of the fabric.

[0082] The rotating shaft 435 is rotatably arranged on the front and rear sides of the mounting bracket 42, and the rotating shaft 435 is located on the front and rear sides of the transmission shaft 431;

[0083] Gear 2 436 is arranged on the rotating shaft 435, and Gear 2 436 meshes with Gear 1 432;

[0084] The chute 437 is opened on the mounting bracket 42, and the chute 437 penetrates through the mounting bracket 42;

[0085] The rack 438 is slidably arranged in the chute 437, and the detection plate 44 is arranged between the tops of the two racks 438;

[0086] The sector gear 439 is arranged on the rotating shaft 435. The sector gear 439 on the front side meshes with the rack 438, and the tooth part of the sector gear 439 on the rear side faces away from the rack 438.

Gear 2 436 is arranged on the rotating shaft 435, and Gear 2 436 meshes with Gear 1 432 for transmitting power and rotation. The chute 437 penetrates through the mounting bracket 42 for supporting and guiding the movement of the rack 438. The rack 438 is slidably arranged in the chute 437, and the rack 438 is a key component connecting the detection plate 44. The sector gear 439 is installed on the rotating shaft 435. The tooth part of the sector gear 439 on the front side meshes with the rack 438, and the tooth part of the sector gear 439 on the rear side faces the back of the rack 438 for driving the up and down movement of the rack 438.

[0088] Working process: When it is necessary to detect the elasticity of the fabric, the motor 434 is started, and its output shaft rotates. The motor 434 drives the transmission shaft 431 to rotate, and the transmission shaft 431 drives the first gear 432 to rotate. The first gear 432 meshes with the second gear 436, causing the second gear 436 to drive the rotating shaft 435 to rotate. The rotating shaft 435 drives the sector gear 439 to rotate. The front sector gear 439 meshes with the rack 438, causing the rack 438 to move upward along the chute 437. The rack 438 drives the detection plate 44 to move upward. The detection plate 44 contacts the fabric and squeezes the fabric, causing the fabric to stretch and deform. The elasticity of the fabric is detected by the pressure sensor 45, and the detected information is sent to the data processing unit 46. The data processing unit 46 processes the elasticity information and displays the processed information through the display unit 47. The sector gear 439 continues to rotate, causing the front sector gear 439 to disengage from the rack 438. The tooth part of the rear sector gear 439 meshes with the rack 438 and transmits power, causing the rack 438 to move downward along the chute 437. The rack 438 drives the detection plate 44 to move downward. The detection plate 44 drives the pressure sensor 45 to move downward. The detection plate 44 disengages from the fabric. Finally, the motor 434 is turned off. In this way, the detection plate 44 can be driven to detect the elasticity of the fabric.
