Description

Tension constant device for winding and unwinding wires of winding machine

Technical Field

The utility model relates to a tension control device of a winding machine, in particular to a tension constant device of a take-up and pay-off wire of the winding machine; the tension constant device for the coiling and uncoiling of the coiling machine can ensure constant tension in the coiling and uncoiling processes of the coiling machine; belonging to the technical field of winding machine control.

Background

At present, a plurality of winding machines are available on the market, and various coils, such as transformer coils, reactor coils and the like, are wound by gradually using the winding machines; the winding machine tension controller is a key component for generating adjustable tension when the winding machine winds the coil, so that the enameled wire is provided with proper tension when winding, the wound coil is proper in tightness and full in fastening, and the consistency of technical indexes of the coil is guaranteed. Currently, there are many types of tension controllers for winding machines, and they are roughly classified into a servo type tensioner, an electronic type tensioner, a magnetic force, a magnetic type tensioner, and a mechanical type tensioner from high to low in terms of performance advantages.

However, the existing tension controllers generally have some defects, and although the winding process can realize wire arrangement (wire paying-off) and wire winding, the existing tension controllers cannot pay off, take up and store wires according to the production requirements, and particularly the wire paying-off speed cannot be flexibly accelerated or decelerated according to the production requirements. Particularly, the existing large-scale transformer coil winding adopts a magnetic powder brake or a pneumatic disc to provide paying-off tension without taking-up function. Although the magnetic powder brake with the distance measuring sensor structure can provide constant tension in the winding process, the magnetic powder brake does not have the winding function and does not provide tension after shutdown; the tension provided by the pneumatic disc structure is unstable, and the wire collecting function is not realized; the quality of the initial winding is influenced, and other manual operations such as tap welding and the like in the winding process are influenced due to the fact that the wire collecting function is not provided. There is therefore a great need for improvement.

Through patent search, no patent technical literature reports related to the content of the utility model are found, the most relevant patent literature is some relevant patent literature, and the most relevant literature has the following:

1. the utility model has the patent number of CN201821217989.1 and is named as a wire collecting and releasing device of a transformer winding machine, and discloses a wire collecting and releasing device of a transformer winding machine, which comprises a frame, an automatic moving straightening mechanism and a base; the base is arranged at the lower end of the frame; the upper end of the left side of the frame is provided with an automatic moving straightening mechanism; a wire coil is arranged at the lower side of the automatic moving straightening mechanism; the right side of the wire coil is sequentially provided with a bearing seat and a magnetic powder clutch, the magnetic powder clutch and the bearing seat are fixedly arranged on the rack, and the right end of the rack is provided with a speed reducer; a connecting shaft is inserted into the wire coil and fixedly connected with the wire coil; the left end of the connecting shaft is provided with a wheel, and the right end of the connecting shaft is connected with the coupling through a bearing seat; the right end of the coupler is connected with an output shaft of the magnetic powder clutch, and an input shaft of the magnetic powder clutch is connected with the speed reducer; the right end of the speed reducer is connected with an output shaft of the transformer winding machine, and the upper end of the speed reducer is provided with a motor; a wire placing frame and a tension controller are arranged outside the frame; the tension controller is connected with the magnetic powder clutch through an electric wire. Although the patent mentions wire winding, the wire winding is only wound by the reverse rotation of the motor, and the wire winding is not controlled by constant tension.

2. The patent number is CN202021046031.8, the name is "a utility model of power transformer high-voltage coil automatic winding machine", this patent discloses a power transformer high-voltage coil automatic winding machine, including main frame, electromagnetic wire unwrapping wire frame, insulating paper blowing frame, solenoid winding device, solenoid discharge device and control system, electromagnetic wire unwrapping wire frame is installed in the top of main frame, and through first ball screw drive mechanism and main frame front and back sliding connection, first ball screw drive mechanism is connected with first servo motor, be provided with circle line pay-off, electromagnetic wire flattening device and constant tension winding displacement device on the electromagnetic wire unwrapping wire frame, insulating paper blowing frame is located the below of constant tension winding displacement device, and through second ball screw drive mechanism and main frame front and back sliding connection, second ball screw drive mechanism is connected with second servo motor, an interlayer insulation discharging device and an end insulation feeding device are arranged on the insulation paper discharging rack. Although the patent mentions a constant tension flat cable, the patent does not have constant tension control during take-up.

3. The patent number is CN202022530647.9, the name is "a constant tension winding displacement mechanism", this patent discloses a constant tension winding displacement mechanism, including rotating the line roller assembled on the framework, drive the positive and negative rotation by the first electrical machinery in order to realize taking up and paying off the line; a wire wheel is positioned above the wire roller, a wire inlet end or a wire outlet end of the wire wheel is vertically arranged above the wire roller corresponding to the wire roller, and a wire is tangent to the circumferential surface of the wire roller; the wire wheel is rotatably assembled on the sliding seat, the sliding seat is driven by a second motor to reciprocate on the rack along a straight line, and the straight line of displacement is parallel to the axis of the wire roller; the wire wheel is provided with a tension sensor which is electrically connected with a control circuit, and the control circuit is electrically connected with a second motor; the wire wheel swings around a swinging shaft, and the axis of the swinging shaft is parallel to the axis of the wire roller. However, the patent only adjusts the horizontal position of the wire wheel in real time through the tension of the real-time detection line so as to keep the tension constant, and on the other hand, the wire wheel is arranged on a swinging shaft so as to be capable of swinging freely, so that the tension of the paying-off line can be controlled only by matching the change of the tangent point of the wire and the wire wheel.

Through the analysis of the above patent documents, we find that although tension control of a winding machine is involved, even some improved technical solutions for tension control of winding are proposed, after careful analysis, these technical solutions are still lack of good technical solutions for tension control when winding and rewinding are performed, and especially for winding large transformer coils, a magnetic powder brake or a pneumatic disc is adopted to provide unwinding tension without a winding function, and no improvement measure is proposed, so the aforementioned problems still exist, and further research is still needed.
