Adjustment mechanism and method for automatic adjustment of multilayer yarn screen edge layer difference

Abstract

The invention provides an adjustment mechanism and method for automatic adjustment of multilayer yarn screen edge layer difference. The adjustment mechanism comprises a controller, a yarn camera recognition mechanism, a first pressing mechanism and a second pressing mechanism. The yarn camera recognition mechanism is used for judging layer difference distance of different layers of yarn screen edges, the first pressing mechanism is used for fixing one end of multilayer yarn screens, and the second pressing mechanism is used for fixing the other end of the multilayer yarn screens. The first pressing mechanism comprises a fixed pressing box for fixing different layers of the yarn screens, and the second pressing mechanism comprises a supporting frame and a plurality of movable pressing boxeson the supporting frame. The invention further provides an adjustment method for automatic adjustment of multilayer yarn screen edge layer difference. The adjustment mechanism and the method have advantages that bilateral positional difference of different layers of yarn edges can be judged through the yarn camera recognition mechanism, the corresponding movable pressing boxes are automatically controlled to move bilaterally to reduce or eliminate the bilateral difference of the yarn edges of closer layers, and accordingly quick and continuous operation of automatic equipment can be realized.

Description

technical field [0001] The invention relates to textile equipment, in particular to an adjusting mechanism and method for automatically adjusting the edge level difference of multi-layer wire curtains. Background technique [0002] With the deepening of automation in the textile industry, the popularization of automation equipment, the types of yarns, and the increase in width and pattern of cloth, there are more and more cases where two or more warp beams are threaded together or merged into one line by passing through sub-strands. scene. [0003] When processing multiple warp beams on the automatic drawing-in equipment or automatic splitting equipment, due to the difference in the number and density of each warp beam yarn and the error of the operator's operation, the adjacent layers of yarn will be The left and right positions of the edges cannot be aligned. When the distance between the adjacent upper and lower yarn edges exceeds a certain value, the existing automatic ...

Problems solved by technology

[0003] When processing multiple warp beams on the automatic drawing-in equipment or automatic splitting equipment, due to the difference in the number and density of each warp beam yarn and the error of the operator's operation, the adjacent layers of yarn will be The left and right positions of the edges cannot be aligned. When the distance between the adjacent upper and lower yarn edges exceeds a certain value, the existing automatic threading equipment or automatic twisting equipment will repeatedly search for the thread curtain and cannot continue to work. The process will cause problems such as loose wire curtain and shaking of the host, which will seriously affect the working efficiency of the automation equipment and even reduce the service life of the automation equipment

When the left and right distance of the edge of the wire curtain is too large, it will cause downtime or damage to the wire curtain
