Description
Technical Field
The utility model relates to the field of data cable preparation, in particular to a wire take-up tension display device of a pair twisting machine.
Background
With the development of 5G digital communication networks in China, a large number of high-quality data cables are needed. The company provides special technical equipment for data cable manufacturers, wherein the twisted pair equipment is used most in the data cable production and is also equipment which affects the quality of the data cable greatly.
In the electrical performance standard of data cables, an important index is ensured by a pair twisting machine, namely near-end crosstalk attenuation, and for the structure of the data cables, the twisted pair pitches of twisted wires must be consistent. The inconsistent pitch is the main reason for the unqualified near-end crosstalk attenuation index of the data cable.
In the stranding process of a stranding machine, if the take-up tension is too small, the friction force of a traction wheel on the stranded wire is not large enough, the stranded wire slips in the moving process, and the twisted pair pitch is one; the copper conductor in the stranded wire can be thinned due to overlarge take-up tension, so that the take-up tension is particularly important to display in the stranded wire production process, and an operator can know the size of the take-up tension through the take-up tension display and can adjust the take-up tension in time.
The winding-up of the pair twister is in the middle of a rotating body of a rotating twisting bow, the electronic display method is difficult, and digital signals are not easy to transmit through an electric brush slip ring and are easy to interfere.
Therefore, how to design a mechanically operated wire take-up tension display device of the pair twister is particularly important.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model aims to provide a pair twister take-up tension display device.
In order to realize the purpose of the utility model, the adopted technical scheme is as follows:
a pair twister receipts line tension display device includes:

Detailed Description
The pair twister take-up tension display device shown in fig. 1 or 2 comprises a mounting bracket body 100 for mounting other components, wherein the mounting bracket body 100 comprises a first bracket 110 and a second bracket 120 mounted on one side of the upper part of the first bracket 110.
The linear guide 130 is disposed inside the first bracket 110, and the first guide pulley 200 is perpendicular to the linear guide 130.
A pointer 210 is arranged on the lower shaft of the first guide wheel 200; the pointer 210 moves by the first guide wheel 200 and indicates the number on the scale 300.
A compression spring 140 is connected between the side wall of the first bracket 110 and the first guide wheel 200. The height of the pressure spring 140 is lower than that of the central axis 201 of the first guide wheel 200.
The stranded wire 500 is wound on the first guide wheel 200 from the lower end tangent plane 202 of the first guide wheel 200 and then is wound out from the upper end tangent plane 203 of the first guide wheel 200, and then is wound into the second guide wheel 400 from a side tangent plane 401 of the second guide wheel 400 close to the first guide wheel 200 and then is wound out;
the height of horizontal shaft 402 of second guide wheel 400 is flush with upper end tangent plane 203 of first guide wheel 200.
When the tension of the twisted wire 500 is large, the first guide roller 200 moves toward the inside, and when the tension of the twisted wire 500 is small, the first guide roller 200 moves toward the outside. By utilizing the linear characteristics of the compression amount and the pressure of the compression spring 140, the invisible strand tension is intuitively displayed by pointing the pointer 210 to a certain scale.
Therefore, an operator can master the wire winding tension in production through the observation window of the pair twisting machine, and qualified and high-quality data cables are produced.
The basic principle and the main characteristics of the pair twister take-up tension display device and the advantages of the pair twister take-up tension display device are shown and described.
It should be understood by those skilled in the art that the winding tension display device of the pair twister of the present invention is not limited by the above embodiments, and the above embodiments and the description are only for illustrating the principle of the winding tension display device of the pair twister of the present invention.
The pair machine take-up tension display device of the utility model can also have various changes and improvements which fall within the scope of the claimed pair machine take-up tension display device of the utility model without departing from the spirit and scope of the pair machine take-up tension display device of the utility model.
The claimed protection scope of the wire-rewinding tension display device of the pair twister is defined by the appended claims and the equivalents thereof.
