Abstract

The utility model discloses a pay-off stand. The pay-off stand comprises a frame, a pay-off spool, a dancer roller and a transitional guide wheel, and further comprises a motor, a main transmission shaft, a friction disc and a driven shaft, wherein, the motor is provided with a power take-off shaft; the main transmission shaft is fixedly connected with the power take-off shaft of the motor; the friction disc is fixedly connected with the main transmission shaft; the root of the driven shaft is arranged on the frame in a slideable manner; one end of the pay-off spool is in joint with the friction disc, and the other end thereof is in rotational connection with the tip end of the driven shaft; and a regulating mechanism used for regulating the position of the driven shaft relative to the frame is also arranged on the frame. The utility model can regulate friction force between the pay-off spool and the friction disc by regulating the position of the driven shaft relative to the frame, thereby regulating the pay-off tension of the pay-off spool. The utility model has the advantages of simple regulating mechanism, convenient regulating process, and high control precision.

Description

Pay off rack

Technical field

The utility model relates to a kind of pay off rack, and it is used to be mainly in cable, the optical cable industry production process tight cover unwrapping wire.

Background technology

Pay off rack mainly is made up of draw drum, transition guide wheel, the wheel of dancing, and core is emitted from draw drum, through the transition guide wheel, on the wheel of dancing after the winding multiple tracks, the core tension stability, does not have the situation of beating, and just can enter next step operation.Corresponding to the different product model, often need to regulate the tension force of core, most tension adjustment trouble of existing pay off rack and Tension Control precision are not high.

The utility model content

Technical problem to be solved in the utility model provides the simple and high pay off rack of Tension Control precision of a kind of tension adjustment.

For solving above technical scheme, the utility model is taked following technical scheme: a kind of pay off rack comprises framework, rotates the draw drum be arranged on the framework, rotates the dancing wheel that is arranged on the framework, the transition guide wheel that is used for core is imported from draw drum the wheel of dancing.This pay off rack also comprises the motor with power take-off shaft, the main driving axle of captiveing joint with the power take-off shaft of above-mentioned motor, the friction disc of captiveing joint with described main driving axle; This pay off rack also comprises the driven shaft that is provided with the main driving axle coaxial inner conductor, and the root of described driven shaft and framework slide and be provided with; The taper of one end of described draw drum and described friction disc applying, the other end and described driven shaft is rotationally connected; Also be provided with the regulating mechanism that is used to regulate the relative frame position of driven shaft on this framework.

Described regulating mechanism comprises the clamping cylinder that is fixed on the framework, be used to control the hand propelled electromagnetic valve of the telescopic shaft elongation of described clamping cylinder, and described driven shaft is also captiveed joint with the telescopic shaft that clamps cylinder.

The material of described framework is an aluminum alloy.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage: just can adjust friction force between draw drum and the friction disc by the position of regulating the relative framework of driven shaft, and then the laying tension of adjustment draw drum, regulating mechanism is simple, adjustment process is convenient and control accuracy is high.

Description of drawings

Fig. 1 looks part sectional view for master of the present utility model;

Wherein, 1, framework, 2, main driving axle, 3, reducing motor, 4, fixed side, 5, friction disc, 6, draw drum, 7, driven shaft, 8, clamp cylinder, 9, the accurate adjustment valve, 10, permanent tension force cylinder, 11, the wheel of dancing, 12, the hand propelled electromagnetic valve, 13, the transition guide wheel.

The specific embodiment

Referring to pay off rack shown in Figure 1, mainly comprise four parts: the framework 1 of aluminium alloy extrusions, drive configuration, laying tension adjustment structure, storage line structure, above-mentioned drive configuration, laying tension adjustment structure, storage line structure are two covers that are arranged symmetrically on the framework 1, can independently use or the use simultaneously of two covers.

Its concrete structure is: drive configuration---reducing motor 3 rotates and is arranged on the described framework 1, and the laying tension adjustment structure comprises the main driving axle 2 on the power take-off shaft that is fixedly connected on reducing motor 3, is fixedly connected on the friction disc 5 on the main driving axle 2.

The laying tension adjustment structure also comprises the driven shaft 7 that is provided with main driving axle 2 coaxial inner conductors, the root of described driven shaft 7 and framework 1 slide and are provided with, the clamping cylinder 8 that is fixed with on the described framework 1, be used to control the hand propelled electromagnetic valve 12 of the telescopic shaft elongation of described clamping cylinder 8, described driven shaft 7 is also captiveed joint with the telescopic shaft that clamps cylinder 8, then can control the stroke of driven shaft 7 relative frameworks 1 by control hand propelled electromagnetic valve 12.

One end of draw drum 6 is captiveed joint with described friction disc 5, the taper of the other end and described driven shaft 7 is rotationally connected, can control friction force between draw drum 6 and the friction disc 5 by the stroke of control driven shaft 7 relative frameworks 1, and then the tension force of the core of emitting on the control draw drum 6, adapt to the different process requirement.

The storage line structure comprise rotate the dancing wheel 11 be arranged on the framework 1, be used to control dance wheel 11 tension force permanent tension force cylinder 10, be used to control the telescopic shaft elongation of permanent tension force cylinder 10 accurate adjustment valve 9, be used for core is imported from draw drum 6 the transition guide wheel 13 of the wheel 11 of dancing, core twines multiple tracks on the wheel 11 of dancing, unwrapping wire is beated and eliminated substantially.

This device is compared existing apparatus and is had following advantage:

1), whole framework 1 is installed and is built the aluminium alloy profile as main material, not only outward appearance is beautiful for it, easy to process, the more important thing is its intensity height (aluminium alloy that has can reach the intensity of No. 45 steel), and (being 1/3 weight of steel) in light weight, installation or resettlement are especially convenient, more are fit to the site layout project in workshop;

2), after the wheel 11 of dancing twines the storage lines through multiple tracks, the unwrapping wire elimination of beating, tension force control is more stable, and the winding process operation is especially convenient;

3), laying tension not only online adjustable, execute-in-place is convenient and swift, and the scope of adjustment of tonicity and precision significantly improve, and more is fit to the unwrapping wire requirement in small tension receiving coil and the especially strict situation of technology.
