A kind of draught line stabilizing device
Technical field
The present invention relates to cable and produce the apparatus technical field, relate in particular to a kind of draught line stabilizing device.
Background technology
Cable, in the process of producing, need to be wound up into wire rod on another reel from a reel traction, and from the unwrapping wire reel, the wire rod motion, through various device, finally is wound on take-up block.Because the technological process of production has realized automation mechanized operation, so production efficiency is higher.In prior art, what the motion-promotion force of wire rod was single is provided by take-up place, and when take-up place power size variation, wire rod can become flexible, and therefore, must keep take-up place power is definite value, causes the wire rod kinematic velocity uncontrollable.
Summary of the invention
In order to solve the technical matters existed in background technology, the present invention proposes a kind of draught line stabilizing device, realized traction and the speed governing operation of draught line, it is simple in structure, can be adjusted the kinematic velocity of draught line.
A kind of draught line stabilizing device that the present invention proposes, comprise the first track adjusting wheel for inlet wire, steady wheel and for the second track adjusting wheel of outlet, described steady wheel center is connected with the actuating device that can drive described steady wheel to rotate, described the first track adjusting wheel, described the second track adjusting wheel, the center shaft of described steady wheel is parallel to each other, described draught line enters described steady wheel through described the first track adjusting wheel, and on described steady wheel around entering described the second track adjusting wheel after a circle, described steady wheel diameter is more than three times of described the first track adjusting wheel diameter, described the second track adjusting wheel diameter is consistent with described the first track adjusting wheel diameter, outlet point on described steady wheel and described the first track adjusting wheel are positioned at the same side of described steady wheel upper incoming line point, and the inlet wire point on described steady wheel and described the second track adjusting wheel are positioned at the same side of outlet point on described steady wheel.
Preferably, be provided with the groove that can hold described draught line on described steady wheel.
Preferably, described actuating device is the adjustable variable-frequency motor of output speed, and the output sleeve of described variable-frequency motor is connected to the center shaft position of described steady wheel.
Preferably, the bottom land line of centers of described groove is positioned at the centre of described steady wheel wheel face.
In the present invention, draught line is walked around the first track adjusting wheel, steady wheel, the second track adjusting wheel successively, by actuating device, drive steady wheel to rotate, because the steady wheel diameter is larger, the stroke of draught line on steady wheel is longer, can provide power for the motion of draught line by the friction force between steady wheel and draught line, thereby by steady wheel, draught line be drawn, simultaneously, the steady wheel diameter also makes greatly and can be adjusted the kinematic velocity of draught line by the rotating speed of adjusting steady wheel; The same side that outlet point on the employing steady wheel and the first track adjusting wheel are positioned at steady wheel upper incoming line point, inlet wire point on steady wheel and the second track adjusting wheel are positioned at the such design plan in the same side of outlet point on steady wheel, can ensure that draught line can not interfere on steady wheel.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of draught line stabilizing device of proposing of the present invention.
The specific embodiment
As shown in Figure 1, the structural representation that Fig. 1 is a kind of draught line stabilizing device of proposing of the present invention.
With reference to Fig. 1, a kind of draught line stabilizing device that the present invention proposes, comprise the first track adjusting wheel 1 for inlet wire, steady wheel 2 and for the second track adjusting wheel 3 of outlet, steady wheel 2 centers are connected with the actuating device 5 that can drive steady wheel 2 to rotate, the first track adjusting wheel 1, the second track adjusting wheel 3, the center shaft of steady wheel 2 is parallel to each other, draught line 4 enters steady wheel 2 through the first track adjusting wheel 1, and on steady wheel 2 around entering the second track adjusting wheel 3 after a circle, steady wheel 2 diameter are more than three times of the first track adjusting wheel 1 diameter, the second track adjusting wheel 3 diameter are consistent with the first track adjusting wheel 1 diameter, outlet point 7 on steady wheel 2 and the first track adjusting wheel 1 are positioned at the same side of steady wheel 2 upper incoming line points 6, and the inlet wire point 6 on steady wheel 2 and the second track adjusting wheel 3 are positioned at the same side of outlet point 7 on steady wheel 2.
In the specific design process, be provided with the groove that can hold draught line 4 on steady wheel 2, the bottom land line of centers of groove is positioned at the centre of steady wheel 2 wheel faces, by groove is set, can improve draught line 4 on steady wheel 2 around stability, difficult coming off.
In the specific design process, actuating device 5 is the adjustable variable-frequency motor of output speed 5, and the output sleeve of variable-frequency motor 5 is connected to the center shaft position of steady wheel 2, adopts 5 pairs of steady wheels 2 of variable-frequency motor to be driven, and it is simple in structure and speed governing convenient.
In the present invention, draught line 4 is walked around the first track adjusting wheel 1, steady wheel 2, the second track adjusting wheel 3 successively, by actuating device 5, drive steady wheel 2 to rotate, because steady wheel 2 diameters are larger, the stroke of draught line 4 on steady wheel 2 is longer, can provide power for the motion of draught line 4 by the friction force between steady wheel 2 and draught line 4, thereby drawn by 2 pairs of draught lines 4 of steady wheel, simultaneously, steady wheel 2 diameters also make greatly and can be adjusted the kinematic velocity of draught line 4 by the rotating speed of adjusting steady wheel 2; The same side that outlet point 7 on employing steady wheel 2 and the first track adjusting wheel 1 are positioned at steady wheel 2 upper incoming line points 6, inlet wire point 6 on steady wheel 2 and the second track adjusting wheel 3 are positioned at the such design plan in the same side of outlet point 7 on steady wheel 2, can ensure that draught line 4 can not interfere on steady wheel 2.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
