Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and particularly to a warp knitted fabric measuring mechanism. Background Technique

[0002] The warp knitted fabric produced with polyester filament as raw material has good elasticity. When designing the sample, it can minimize the seams, pleats, splicing, etc. designed for shaping. When actually producing and preparing the warp knitted fabric, a measuring mechanism is often needed to measure the tensile properties of the fabric product. However, there are still some defects when such devices actually operate.

[0003] For example, a super soft moisture-absorbing and hydrophilic functional warp knitted fabric measuring device disclosed in the application number 202321899839.4 includes: a main body and a fixing mechanism. The fixing mechanism is arranged at the top of the bottom of the main body. During use, through the setting of the fixing mechanism, the warp knitted fabric can be effectively fixed, avoiding the situation that one end of the warp knitted fabric slips out of the clamping block during the tensile force measurement, resulting in inaccurate measurement data and the need for repeated measurements. First, pull the pull block outwards. The pull block drives the return spring and the bolt to pull backward. Then, place one end of the warp knitted fabric in the middle of the winding disc. At this time, hold the crank and rotate it clockwise. The crank drives the winding disc to rotate, so that a part of the warp knitted fabric is received inside the winding disc. At this time, release the pull block, and the bolt is snapped into the first limit hole and the second limit hole through the resilience of the return spring, making the winding disc unable to rotate, thus effectively guaranteeing the fixation of the warp knitted fabric; however, it still has the problem that it can only achieve the measurement and processing of a single orientation of the fabric product at one time, and the measured tensile force data is not easy to monitor in real time, and the fabric measurement situation is not easy to collect through a camera, which leads to poor use effect, single function, and not easy to promote.
