Abstract

The invention relates to a variable-frequency and servo-linkage control system and method for spinning of a spinning frame. The system comprises a HMI (human machine interface) unit, a PLC (programmable logic controller), three positioning units, a spindle frequency converter, five servo drivers, a variable-frequency motor, five servo motors, five transmission shafts and four detection units, andthe PLC is connected with the HMI unit. The system solves the problems of unstable frequency converter open-loop control, uneven spun yarn levelness and inconsistent spun yarn forming tightness degreeand the like, spinning and forming accuracy, quality and uniformity are greatly improved, and spinning quality requirements can be met as for high-count, high-density and high-quality spinning. According the system, spinning accuracy and spinning quality are ensured, complicacy and high cost of a full-servo control method are avoided, and the novel control system and method is economical and practical.

Description

technical field [0001] The invention relates to a novel control transmission system method for cotton and flax spinning frames, in particular to a frequency conversion and servo linkage control system and method for spinning frames, belonging to the technical field of spinning. Background technique [0002] Spinning frame is a spinning machine that draws, twists, and winds semi-finished roving or sliver into spun bobbins during the spinning process. Spinning frame is the main machine for spinning, and the output and quality of spinning are a comprehensive reflection of the pros and cons of each process in the spinning process. [0003] The traditional spinning frame uses complex mechanical gears and cam structures to change the purpose of the yarn process by tediously replacing the mechanical gears. The structure is complex, the mechanical transmission wears a lot, and the process change is troublesome. Machine stability and other defects. It is gradually being eliminated ...
