Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of fabric detection equipment, in particular to a textile fabric tensile strength detection equipment. BACKGROUND
[0002] Textile fabric is a kind of cloth formed by weaving. In the process of cloth processing and production, in order to keep the cloth out of the factory in the form of qualified products, the cloth needs to be quality detected before leaving the factory. The tensile strength of the fabric is one of the important indicators to measure its quality and performance. The tensile strength refers to the maximum tensile force that the fabric can withstand without breaking when subjected to external force. This performance is crucial for predicting the durability and reliability of the fabric in use.
[0003] Traditional tensile detection mostly relies on manual cloth laying, alignment, clamping, stretching and recording. The operation process is complicated, time-consuming, low in detection efficiency, and highly dependent on the skills of operators. The fabric clamping is unstable, easy to slip or deform. The ordinary clamping mechanism is simple in design, and the clamping force is uneven or the surface of the clamp is insufficient in friction, which leads to fabric slipping, damage or large test error. The force is not evenly applied, and the results have poor repeatability. The primary electric stretching device cannot realize stable, constant-speed, bidirectional synchronous stretching. The results are affected by test speed fluctuation and fabric pre-tension control, and have poor repeatability. Most of the equipment only detects the tensile performance, and the excess part of the edge cannot be automatically processed, which needs to be cut separately, which is not conducive to the connection of subsequent production processes. Most of the old detection equipment only has the function of tensile test, and cannot realize the automatic detection process of synchronous conveying, clamping, cutting and output of the fabric.

[0027] Working principle: The testing platform 1 is used as the carrier of the entire equipment, and is respectively provided with an elevated suspension platform 5 and a recessed main hydraulic extension 4. The suspension platform 5 is used as a working platform for tensile testing of textile fabrics, and an output bearing mechanism 6 for carrying platform adjustment and fabric transportation is installed on the top of the suspension platform 5. The main hydraulic extension 4 is used to drive the testing pressing cover 3 to move along the circumference of the pressing traction rod 2 installed on the testing platform 1, and drive the extension driving mechanism 7 and the end clamping mechanism 8 for pulling testing to cover the output bearing mechanism 6.
