Description

Bare wire paying-off system of horizontal enamelling machine for producing oversized enamelled round wires

Technical Field

The utility model belongs to horizontal enamelling machine field, concretely relates to naked line unwrapping wire system of horizontal enamelling machine of production super large specification enamelled round wire.

Background

As is well known, in the production process of a copper-clad aluminum enameled wire, the copper-clad aluminum enameled wire needs to be subjected to painting treatment, and a vertical enamelling machine and a horizontal enamelling machine are arranged on the market, so that for the vertical enamelling machine, the process of adopting multiple painting processes is adopted for gradually painting, namely, after one painting process, one baking process is carried out, and although the painting operation of the wire rod can be realized, the implementation mode is directed to the large-sized enameled wire, such as: 2.0-4.0mm, it has the following drawbacks:

1) the outer diameter of the enameled wires is gradually increased after the enameled wires are subjected to multi-pass painting due to the fact that the same constant-speed wheel is used in multiple processes, so that tension formed by the enameled wires is unequal, breakage often occurs, once the enameled wires are broken, the dropped enameled wires interfere with other enameled wires, and the enameled wires are possibly twisted together with (or wrapped around) other enameled wires, so that the rejection rate is extremely high, the enameled wires are not convenient to process, and the production cost is extremely high;

2) in the vertical painting process, due to the self weight of the paint, if a special painting mold is not adopted, the paint is difficult to be uniformly coated on the surface of the wire rod, so that the paint on the surface of a product is not uniform, and the quality of an enameled wire is influenced;

3) the enamelling machine has a huge structure and large occupied space, and a drying oven is needed after each painting, so that the use cost of the equipment is very high.

Although the problem of wire breakage interference can be solved for the horizontal enamelling machine, the problem has an obvious defect: at present, all horizontal enamelling machines aim at the enamelling and coating of small-sized (about 1.0 mm) enamelled wires, and once the outer diameter of the enamelled wire is 2.0-4.0mm (even more than 4.0 mm), the enamelled wire has the defect of the above 1), and the tension formed by a plurality of enamelled wires is unequal, so that wire breakage often occurs.

That is, there are significant defects in the production of large-sized round enameled wires, whether horizontal or vertical, and the following problems occur because the bare wire needs to be unwound from the coil when the bare wire is fed into the enameling machine, and the bare wire is inevitably shaken during unwinding:

1) the bare wires are easy to be aligned and transited or not aligned due to the shaking of the bare wires during paying off, so that the flatness of the bare wires fed into the enamelling machine is difficult to ensure, and the uniformity of subsequent painting is influenced;

2) because the bare wire is a metal wire (such as copper or aluminum) and needs to be subjected to ultrasonic cleaning before being sent into an enamelling machine, once the bare wire is charged with static electricity, the ultrasonic cleaning effect is influenced, and further the subsequent painting is influenced;

3) the tension of the bare wire paying-off is difficult to control, once the tension is too large, the bare wire paying-off is pulled and deformed, painting cannot be uniformly carried out, and the bare wire paying-off is broken by a bit seriously; on the contrary, the tension is too small, which indicates that the bare wire is in a relatively loose state, and if the bare wire is still normally paid off, the bare wire is easy to be accumulated to cause abrasion or break or to be separated from the wire feeding roller.

As shown in fig. 1, the bare wire paying-off system of the horizontal enameling machine for producing the oversized round enameled wire according to the embodiment includes a rolling paying-off device G, a bare wire straightener J, and a tension controller.

Specifically, the rolling pay-off device G comprises an unwinding seat G1, an unwinding shaft G2 arranged on the unwinding seat G1 and a driving component for driving the unwinding shaft G2 to rotate, the tension controller is communicated with the driving component, and the driving component can drive the unwinding shaft G2 to rotate forward and reverse to unwind or wind bare wires.

That is, once the tension is too great, the drive member accelerates unwinding; once the tension is too low, the driving member g3 will reduce the unwinding speed or take up the bare wire directly.

In particular, the drive member is a conventional motor, and as regards the transmission between the motor and the unwinding shaft, a conventional pulley transmission or a gear transmission is possible, which will not be described in detail herein, but is clear and capable of being implemented.

Referring to fig. 2, a bare wire straightener J is disposed between a rolling pay-off G and a wire feeding wheel S.

Specifically, the bare wire paying-off system J comprises a straightening seat 1, a plurality of straightening rollers 2 arranged on the straightening seat 1, a limiting ring 3, a pair of rubber wheels 4, an electromagnetic coil 5 and a tension wire guide wheel 6.

The straightening seat 1 is in a strip shape and is positioned above the rolling pay-off device G.

A plurality of straightening rollers 2 are distributed on the straightening seat 1 from top to bottom and at intervals in sequence from left to right.

In this example, there are three straightening rollers 2, which are arranged in sequence from top to bottom.

Specifically, two of the three straightening rollers 2 are aligned up and down, and one of the middle straightening rollers is horizontally adjusted and arranged on the straightening seat 1. Not only simple structure can satisfy the alignment needs of the bare wire of different external diameters moreover.

Referring to fig. 3, the distance between the center of the middle straightening roller 2 and the center of the upper straightening roller 2 is L1, the distance between the center of the middle straightening roller 2 and the center of the lower straightening roller 2 is L2, and L1= L2. I.e. an isosceles triangle, L1 and L2 are two waists, respectively.

Meanwhile, the vertical distance between the wheel center of the middle straightening roller 2 and the wheel center of the upper straightening roller 2 is D1, the vertical distance between the wheel center of the middle straightening roller 2 and the wheel center of the lower straightening roller 2 is D2, and D1= D2.

The alignment channel formed by the distribution of the three alignment rollers 2 can not only align the bare wires with a certain swing amplitude, but also can meet the alignment of the bare wires with different outer diameters.

And a limiting ring 3 which is arranged at the inlet end of the straightening channel, namely at the lower part of the straightening seat 1. Specifically, the limiting ring 3 comprises a ring sleeve 30 fixed on the straightening seat 1 and a ring eye 31 arranged in the ring sleeve 30, wherein the ring eye 31 is a porcelain eye, and a bare wire passes through the porcelain eye and enters the straightening channel. The porcelain eye can limit the small-amplitude shaking space of the bare wire on one hand, and on the other hand, avoids the surface abrasion of the bare wire, thereby influencing the subsequent painting uniformity.

In this embodiment, a link rod capable of sliding in the vertical direction is provided at the lower part of the straightening seat 1, and the stopper ring 3 is fixed to the link rod.

The pair of rubber wheels 4 are correspondingly arranged at two opposite sides of the straightening channel and are rotationally arranged on the straightening seat 1 around the axis line of the rubber wheels. Not only can eliminate static, but also can play the effect of supplementary bare wire transport.

Specifically, the pair of rubber wheels 4 includes a left rubber wheel 40 and a right rubber wheel 41, wherein the left rubber wheel 40 and the right rubber wheel 41 are respectively arranged on the straightening base 1 in a manner of being laterally and horizontally adjusted. Thus, the static elimination of bare wires with different outer diameters can be satisfied.

And the electromagnetic coil 5 is arranged between the pair of rubber wheels 4 and the outlet end part of the straightening channel and can pull the bare wires to move towards the pair of rubber wheels or the straightening channel return wire, wherein the bare wires sent out from the outlet end part of the straightening channel pass through the electromagnetic coil 5 and are transmitted to the pair of rubber wheels 4. The main purpose of the electromagnetic coil is to provide instantaneous power to facilitate the paying-off of bare wire when needed, for example: once the tension of the bare wire is too large, the bare wire can be pulled and deformed when being paid off, the painting cannot be uniformly carried out, and the bare wire can be pulled apart a little seriously; on the contrary, the tension is too small, which indicates that the bare wire is in a relatively loose state, and if the bare wire is still normally paid off, the bare wire is easy to be accumulated to cause abrasion or break or to be separated from the wire feeding roller.

In this example, there are two sets of electromagnetic coils 5, and the spiral winding directions of the two sets of electromagnetic coils 5 are opposite, and when one of the electromagnetic coils 5 is energized, the other electromagnetic coil 5 is in a de-energized state. That is, the wire is either fed or returned, so that the transition tension or looseness of the bare wire in the paying-off process is avoided.

The tension guide wheel 6 is arranged on the wire feeding path, the tension controller comprises a tension sensor which is an angle sensor, the tension sensor is respectively communicated with a circuit formed by the two electromagnetic coils 5 and has a tension set value, and once the actual tension value is greater than the set value, one of the electromagnetic coils is electrified and pulls the bare wire to feed the wire to the pair of rubber wheels; once the actual tension value is smaller than the set value, the other electromagnetic coil is electrified and pulls the bare wire to send the wire into the straightening channel. Here, it should be noted that the tension sensor 6 is a conventional product, and when the tension exceeds a set range, either a wire feeding (or a wire compensating) or a wire returning is performed.

Specifically, the tension guide wheel 6 is rotatably arranged around the center of the connecting part, the tension sensor is used for monitoring the deflection angle of the tension guide wheel 6, and when the tension guide wheel 6 deflects upwards and exceeds the upper limit of the set angle, the actual tension value is smaller than the set value; when the tension guide wheel 6 deflects downwards and exceeds the lower limit of the set angle, the actual tension value is larger than the set value; when the tension guide pulley 6 is between the lower limit and the upper limit of the set angle, it is said that the actual tension value is equal to the set value.

In summary, the bare wire paying-off process of the embodiment is as follows:

the bare wire is unwound from the rolling pay-off device G, enters the straightening channel through the porcelain eye, is sent out from the pair of rubber wheels 4 through the electromagnetic coil 5, and then bypasses the wire feeding wheel S and the tension guide wheel 6 to be conveyed to the cleaning equipment of the horizontal enamelling machine.

Meanwhile, in the paying-off process, once the tension is overlarge, the self-rolling paying-off device G accelerates the unwinding, and meanwhile, under the condition that one electromagnetic coil 5 is electrified, the bare wire is pulled to be transmitted to a horizontal enamelling machine so as to relieve the transitional tension state of the bare wire; on the contrary, once the tension is too small, the bare wire is in a relatively loose state, the bare wire is wound by the self-rolling pay-off device G, and the other electromagnetic coil 5 is electrified to pull the bare wire to feed the wire into the calibration channel, so that the winding of the bare wire is facilitated.

The present invention has been described in detail, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, and the protection scope of the present invention should not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
