The invention relates to an on-line detection device for a warp beam of a warp knitting machine. The on-line detection device comprises a support part and a detection part. The detection part comprises a rotary shaft, a shaft sleeve, two pressing wheels and a sensor, wherein a support shaft and a pressing shaft are movably connected by a bearing base, and both ends of an elastic element act on the support shaft and the pressing shaft respectively; the rotary shaft and the shaft sleeve are connected by a bearing sleeve, margins are reserved at both ends of the shaft sleeve respectively, the two pressing wheels are fixed on the marginal positions at both ends of the rotary shaft respectively, and the shaft sleeve is movably connected with the circumference of the pressing shaft; and a signal output end of the sensor is connected with an input end of a computer control system of the warp knitting machine. The on-line detection device has the advantages of simple structure, accurate and stable detection and suitability for intelligent and automated warp knitting machine-controlling systems, and can also meet the modernized high-speed and high-precision production requirements.
Description
technical field [0001] The invention relates to an online detection device, which is especially suitable for the let-off control system of a warp knitting machine. Background technique [0002] At present, the let-off control systems of domestic warp knitting machines are mainly mechanical let-off control systems and EBA electronic let-off systems. However, this mechanical let-off mechanism has mechanically complicated maintenance operations, which is very inconvenient, and it is often necessary to manually adjust the warp let-off amount. , and the disadvantages of poor uniformity of the fabric surface, slow speed, easy yarn breakage, and loud noise are middle and low-end products, which are far from meeting the high-quality requirements of modern industry. The existing EBA electronic warp let-off system is basically an open-loop system, mainly relying on the input warp beam parameters, such as outer circumference, inner circumference, number of turns, etc. to calculate the ...
