Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of warp knitting machine especially to a flower comb steel wire transverse moving mechanism of double needle bed warp knitting machine. BACKGROUND

[0002] In the warp knitting machine, the transverse movement and swing movement of the flower comb steel wire need to be highly coordinated with the cylinder assembly and the servo assembly (precision control unit) to ensure the accurate looping of the yarn and the stable weaving of the complex pattern. However, there are the following key problems in the prior art: insufficient synchronization accuracy: the traditional mechanical drive (such as cam, connecting rod) relies on rigid transmission, and the dynamic response of the cylinder action and the servo motor is difficult to match, resulting in phase delay between the flower comb transverse trajectory and the needle bed movement (usually the error is more than ±0.1mm). When weaving at high speed (>2500rpm), the start-stop inertia of the cylinder and the feedback delay of the servo system exacerbate the out-of-sync phenomenon, causing problems such as yarn needle skipping and uneven loops, which affects the fabric yield; high complexity of coordinated control: the swing angle of the flower comb steel wire needs to be dynamically adapted to the transverse amount, but the existing system mostly uses independent control modules, lacks unified timing planning, and results in low multi-axis coordination efficiency (such as mismatch between cylinder pressure fluctuation and servo speed).
