Embodiment 1

[0040] Embodiment 1: Turn on the power switch Q1, the frequency converter Q2 runs, the frequency converter Q2 drives the main motor 1 to run, and the frequency converter Q2 provides 24v DC power to the synchronous device 6 at the same time, with the main motor 1 running, the motor gear 3 passes through the intermediate gear 4. The dial gear 9 and the coupling 8 transmit the running speed of the main motor 1 to the synchronization device 6, and the synchronization device 6 converts the speed information of the main motor 1 into an electrical signal and sends it to the servo driver Q3, and the servo driver Q3 controls the take-up servo motor 10 operates according to the weaving requirements, the take-up servo motor 10 drives the reducer 11, the transmission shaft 12 and the take-up sheave to run, and at the same time, the servo driver Q3 feeds back the operation information of the take-up servo motor 10 to the frequency converter through terminals A- A+ B- B+ The signal receiving...

Embodiment 2

[0042] Embodiment 2: The synchronizing device is directly installed on the main motor 1 of the knitting machine without transmission through the intermediate gear 4 and the dial gear 9, and is connected with the tail end of the motor shaft through a coupling; the main motor 1 rotates to drive the synchronizing device 6 The running signal is sent to control the running speed and running direction of the take-up driving part. The speed of the main motor 1 is accelerated, and the speed of transmission to the synchronous device through the coupling will also be accelerated, the signal sent by the synchronous device 6 will be strengthened, and the servo drive Q3 will change the speed with the change of the synchronous signal. When the main motor 1 When the rotation direction changes, the direction signal sent by the synchronization device 6 will also change accordingly, and the direction of the take-up servo driver Q3 will change with the synchronization signal, so as to ensure the ...

Abstract

The invention belongs to a control device for knitting machinery and relates to a knitting machine main unit and take-up synchronous control device, comprising a master controller and a take-up servocontroller. The master controller controls a stirring disc and a spindle to operate; the take-up servo controller controls a take-up and pay-off device to cooperate with the stirring disc and the spindle to operate synchronously; a frequency converter of the master controller controls a master motor to rotate; the master motor drives a synchronous device to operate synchronously; the synchronous device outputs a control signal to control a servo driver of the servo controller to operate; the servo driver drives the take-up servo motor to operate; the operating state of the take-up servo motoris fed back to the frequency converter through the servo driver; the master motor rotates to drive the synchronous device to operate so as to send out a signal, thereby controlling the speed and operating direction of the take-up servo motor so that closed-loop control is achieved. The knitting machine main unit and take-up synchronous control device has the advantages that a knitting main unit and taking-up can be controlled conveniently to gain synchronous acceleration or deceleration according to a user's demand, pitch of a woven product is not changed during acceleration or deceleration, conveniences are brought to the user of a knitting machine, and product quality is stabilized and improved.

Description

technical field [0001] The invention relates to a control device for a knitting machine, in particular to a synchronous control device for a main machine of the knitting machine and a wire take-up. Background technique [0002] There are more and more types of knitting machines, more and more knitting products, and more and more application fields. We use various accessories, shoelaces, elastic bands, various ropes, shielded wires, automotive wiring harnesses, automotive brake hoses, high-pressure water pipes, high-pressure oil pipes, and various cables for nautical ships, aerospace wiring harnesses, and ignition wires in our daily life. [0003] At present, commonly used knitting machines use gear ratios to adjust the speed. When the speed needs to be adjusted, the gears must be replaced. It is very inconvenient to adjust the speed of the knitting machine; due to the limitation of the number of gear teeth, it cannot meet the needs of various knitting pitches. Although ther...
