Pay-off and take-up device of wire drawing machine

Abstract

The invention provides a pay-off and take-off device of a wire drawing machine. The pay-off and take-off device comprises a wire passing guide wheel, a lead screw, a PLC (programmable logic controller), a proximity switch, a driver and a servo motor, wherein the wire passing guide wheel is arranged on the lead screw in a sleeving mode; the lead screw is driven by the servo motor, so that the wire passing guide wheel on the lead screw is in reciprocating rectilinear movement; the servo motor is connected to the driver; the driver is connected to the PLC for being controlled; the PLC is further connected to the proximity switch; and the proximity switch is mounted on a position opposite to the middle part of the lead screw. According to the pay-off and take-up device of the wire drawing machine, the servo motor and the proximity switch are arranged, so that take-up and reversing are very easy to set and regulate; and by virtue of a man-machine interface, fine regulation for various take-up widths and take-up positions can be realized very well.

Description

technical field [0001] The invention relates to a wire taking-up and arranging device for a wire drawing machine. Background technique [0002] In the prior art, the cable arrangement device is mainly driven by a frequency conversion motor to drive the cable guide to reciprocate and linearly move along the lead screw, the line change approach switch transmits the reversing signal, the protection switch acts as an overtravel protection, and the row width of the I-shaped wheel is adjusted. The position of the reversing switch is manually adjusted and observed, and the reversing of the cable is realized by the reverse operation of the frequency conversion motor. Therefore, because the cable arrangement device relies on the left and right reversing proximity switches to obtain the reversing signal during the reversing of the cable, the cable arrangement mechanism It is necessary to design the installation position of the proximity switch for the left and right cable reversing.

[0002] In the prior art, the cable arrangement device is mainly driven by a frequency conversion motor to drive the cable guide to reciprocate and linearly move along the lead screw, the line change approach switch transmits the reversing signal, the protection switch acts as an overtravel protection, and the row width of the I-shaped wheel is adjusted. The position of the reversing switch is manually adjusted and observed, and the reversing of the cable is realized by the reverse operation of the frequency conversion motor. Therefore, because the cable arrangement device relies on the left and right reversing proximity switches to obtain the reversing signal during the reversing of the cable, the cable arrangement mechanism It is necessary to design the installation position of the left and right cable reversing proximity switch. When reversing the cable, the influence of the reverse acceleration and deceleration of the motor on the effect of the cable must be considered, which is very troublesome.
