Sewing thread tension testing device for screening strength

Abstract

The invention relates to the technical field of sewing thread testing, in particular to a screening strength sewing thread tension testing device which comprises a base, the outer wall of the top of the base is fixedly connected with a winding assembly, the winding assembly comprises an electric telescopic rod fixedly connected to the outer wall of the top of the base, and the output end of the electric telescopic rod is fixedly connected with a fixing plate. A guide rod is fixedly connected to the outer wall of the top of the base, a connecting block is slidably connected to the arc-shaped outer wall of the guide rod, supporting plates are fixedly connected to the connecting block and the outer wall of one side of the fixing plate, and clamping assemblies are rotatably connected to the outer walls of one sides of the two supporting plates. The motor drives the thread pipe to rotate through the sleeve, the sleeve rod and the rubber block, winding work of the sewing thread is achieved, in the winding process, the sewing thread applies upward pulling force to the guide pipe, tension detection is achieved through the second spring and the pressure sensor, tension measurement work is conducted in the winding process, and the working efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of sewing thread testing, in particular to a sewing thread tension testing device with screening strength. Background technique [0002] Sewing thread is the thread required for knitted clothing products. Sewing thread can be divided into three categories according to raw materials: natural fiber, synthetic fiber sewing thread and mixed sewing thread. After the sewing thread is produced, the tension of the sewing thread needs to be tested. There is a need for a sewing thread tension testing device for screening strength. [0003] In the prior art, there are problems as follows: [0004] It is impossible to carry out the tension test in the process of winding the sewing thread. Usually, the sewing thread is wound after the test, which reduces the overall work efficiency. In addition, when the tension test is performed, the limit of the tension cannot be effectively measured. value, resulting in a small meas...

AI Technical Summary

Problems solved by technology

[0004] It is impossible to carry out the tension test during the process of winding the sewing thread. Usually, the sewing thread is rewound after the test, resulting in a decrease in the overall work efficiency. In addition, the tension limit cannot be effectively measured during the tension test. value, resulting in a small measurement range of the existing tension testing device, which reduces the practicality
