Length measuring device of loom

Abstract

The invention discloses a length measuring device of a loom. The length measuring device comprises a rack, wherein the rack is provided with a loom main shaft, a mechanical length measuring mechanism and an electronic length measuring mechanism, the mechanical length measuring mechanism comprises a length measuring wheel, and the length measuring wheel is arranged on the rack through a length measuring wheel seat; the rack is also provided with a transmission mechanism which is used for transmitting the power of the loom main shaft to the length measuring wheel; the electronic length measuring mechanism comprises an electronic length measurer and a pressing wheel, the pressing wheel is positioned above the length measuring wheel, a yarn flying gap is formed by the match of the pressing wheel and the length measuring wheel, the electronic length measurer is positioned above the pressing wheel, the inner part of the electronic length measurer is provided with an encoder which rotates synchronously with the loom main shaft, and the bottom part of the electronic length measurer is provided with an electromagnetic needle directly facing the pressing wheel. According to the length measuring device disclosed by the invention, the structure is simple, the operation is easy, the length measurement of yarn is realized by adopting a matching mode of the electronic length measuring mechanism and the mechanical length measuring mechanism, and the length measuring can be more accurate.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a length measuring device for a loom. Background technique [0002] At present, domestic and foreign textile length measuring devices mainly have two forms: mechanical and electronic. Among them, the mechanical type is mainly composed of gear trains, while the electronic type uses electronic technology and is composed of logic circuits or single-chip microcomputer systems. The existing mechanical measurement Most of the long devices have the problems of low energy efficiency and low precision. Although the electronic length measuring devices have high precision and stable performance, they also have the problems of complex structure, high energy consumption and high cost. [0003] This shows that the prior art needs to be further improved and improved. Contents of the invention [0004] The present invention provides a loom length measuring device in order to avoid the disadva...
