Plastic wiredrawing machine rolling control method and rolling system

Abstract

The invention relates to a plastic wiredrawing machine rolling control method and a rolling system. A plastic wiredrawing machine comprises a first motor for driving rolling of a winding reel, a second motor for driving a spiral reciprocating lead screw to complete rolling figure molding and a frequency changer for controlling the first motor and the second motor. The method comprises the steps that a first pulse number corresponding to the rotating angle of the first motor is obtained; a second pulse number corresponding to the second motor is calculated according to the first pulse number and the preset transmission proportion; the second pulse number is converted into the given frequency corresponding to the second motor; a third pulse number corresponding to the rotating angle of the second motor is obtained; the adjusting frequency of the second motor is obtained according to the error of the first pulse number and the second pulse number; and the given frequency and the adjusting frequency of the second motor are subject to stacked operation to obtain the final output frequency of the second motor. Rolling figure molding is not driven by gear connection any more and is singly driven by the second motor, the gear abrasion phenomenon does not exist, and the equipment stability is improved.

Description

technical field [0001] The invention relates to the field of wire drawing machines, in particular to a winding control method and a winding system of a plastic wire drawing machine. Background technique [0002] The plastic wire drawing machine uses polypropylene and high-density ethylene as raw materials. After heating, extruding, cutting and stretching, the flat yarn is formed into a flat yarn, which is then wound up for circular loom weaving. The winding effect directly determines the quality of the braided belt of the circular loom, and the winding effect mainly includes two parts: the winding tension control effect and the winding forming pattern effect. The control effect of the winding tension depends on the control of the first motor, and the effect of winding and forming patterns depends on the control of the wire arrangement mechanism. [0003] At present, manufacturers of plastic wire drawing machines control the first motor for wire tension control, and the wire...

AI Technical Summary

Problems solved by technology

If the machine is easy to wear and tear, the wire arrangement mechanism and the first motor are connected by gears. During the long-term operation, there will be wear and tear phenomena, especially for plastic wire drawing machines, which generally have a high line speed and wear more seriously. Generally, the gears need to be replaced regularly.
