Description

Ultra-end type concentric cross one point bundled high-speed yarn-bundling device

Technical field

The utility model relates to the high-speed yarn-bundling device in the part of appliance of the part of appliance of optical cable production line, particularly optical cable production line.

Background technology

At present, development along with optical communication industry, the demand of optical cable increases progressively every year significantly, and the disposable procurement demand amount in market is big, and the delivery cycle shortening, and optical cable manufacturer is in order to meet the need of market, reduce cost, proposed the demand of further raising line speed, and the linear velocity of optical cable stranding production line restricts mainly in the rotational speed of yarn yarn bundler and strand platform stranding device, the employed yarn bundler of each manufacturer can reduce following two kinds of versions at present on the whole:

One is, the eccentric yarn bundler of tangentially putting yarn of two groups as shown in Figure 1, its principle of work is: the cable core 1 after stranded passes the axle center of hollow spindle 4, be pulled and do the straight ahead motion, main shaft 4 drives high speed rotating by dragging motor 3 through driving-belt 2, on hollow spindle 4, be equipped with one and make the rotating disc 5 of high speed rotating with this main shaft 4, two (or more than two) yarn coils 6 are being housed on the rotating disc 5, yarn group 6 is through on the yarn clew axis 7 that links to each other with rotating disc 5, yarn group 6 can be freely around yarn clew axis 7 rotations, when yarn advances with cable core 1, yarn just hauls 6 rotations of yarn group to emit yarn, the tension force that yarn is emitted is generally regulated (not shown) by the yarn tension regulating device on guide rod 8 or the yarn clew axis 7, simultaneously, yarn group 6 makes high speed rotary motion with rotating disc 5 and main shaft 4, yarn is through guide rod 8, guide wheel 9 causes cable core 1, thereby yarn has been finished screw type tying up on the surface of cable core 1, this yarn bundler, because yarn group 6 is contained in the outside of main shaft 4, overall dimensions are bigger, and during high speed rotating, moment of inertia and centrifugal force are all very big, thereby the very difficult raising of rotating speed, generally can only reach 800-1000 rev/min.

Two are, concentric type is as shown in Figure 2 tangentially put the yarn bundler of yarn, its principle of work is: the cable core 1 after stranded passes the axle center of hollow spindle 4, be pulled and do the straight ahead motion, hollow spindle 4 drives high speed rotating by dragging motor 3 through driving-belt 2, the hollow yarn clew axis 7 of pair of bearings supporting also is housed in it, the rotary body 10 of a tubular is housed on hollow spindle 4, yarn guide rod 8 and guide wheel 9 are housed in it, after yarn is emitted from yarn group 6, cause cable core 1 through guide rod 8 and guide wheel 9, when yarn and cable core 1 are done forward travel, yarn just hauls 6 rotations of yarn group, to emit yarn, yarn is emitted tension force and is generally regulated (not shown) by the yarn tension regulating device on guide rod 8 or the yarn clew axis 7, after yarn is emitted from yarn group 6, through being contained in rotary body 10 inboard guide rods 8, thereby guide wheel 9 is made the high speed rotary motion yarn and is formed spiral helicine tying up on the surface of cable core 1.This yarn bundler is because yarn group 6 and main shaft 4 concentric rotations, thereby the centrifugal force of yarn group 6 rotations reduces greatly, thereby rotating speed increases, but it still has a tubular rotary body 10 that inertia is very big, so rotating speed still is very restricted, in addition, because yarn group 6 is through on the cable core 1, it is more bothersome more to renew yarn group, so generally all adopt the big yarn group of 5～10Kg, rely on the strength of yarn, the yarn group of pulling 5～10Kg makes high speed rotating, must need bigger strength, so this form is pricked loose thread, though rotating speed can increase, be difficult to reduce but put yarn tension, put yarn tension simultaneously also with the reducing and increase of yarn group diameter, for the optical cable stranding, excessive yarn-binding tension, often cause the stranding added losses to increase, all can't accept on the technology He on the product, in this case, have to reduce and prick the yarn rotating speed, the superiority of concentric type yarn bundler also just can not embody.

In sum, because the yarn bundler rotational speed is slow, line cable industry becomes the cable speed of production not increase, and has restricted the speed of production of optical cable greatly, and labour productivity can't improve.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of ultra-end type concentric cross one point bundled high-speed yarn-bundling device is provided, and it can significantly improve rotational speed, thereby enhances productivity, and correspondingly reduces production costs.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: it comprises by the hollow spindle of driven by motor and yarn group, the yarn clew axis of yarn group is fixedly mounted on the hollow spindle, the main shaft of yarn clew axis one end is provided with and can be provided with tensioner between main shaft and the yarn-discharging device around the arm throwing yarn-discharging device of main axis rotation.

This device is two covers, and the axial line of the main shaft of two covering devices is on same straight line, and the sense of rotation of main shaft is opposite.

Tensioner is fixed on the end of main shaft.

Two yarn groups are installed on the same main shaft simultaneously.

Its principle of work of the utility model is:

Cable core after stranded passes the axle center of hollow spindle, does the straight ahead motion under the drive of traction; The yarn briquetting fixes on the hollow spindle, and hollow spindle carries out high speed rotating by driven by motor, and the yarn of yarn group is emitted by the end through the arm throwing yarn-discharging device of rotation, and is directed at cable core, is banded on the cable core.This device is two covers, and the yarn that the two yarn groups that put emit is intersected in a place on cable core.

Owing to adopted technique scheme, its advantage is:

1, do not have big rotary body, its rotary inertia is little, thereby rotating speed can increase substantially;

2, the tension force of putting yarn is regulated and control by the tensioner on the rotary arm throwing yarn-discharging device, with rotating speed and the vary in diameter of the yarn that uses group irrelevant, can realize that permanent tension force puts yarn, in addition, tensioner is the mechanical type adjustable tension control device, and range of adjustment is very big, therefore can use the yarn group of large-size, reduces and changes the yarn number of times;

3, under the situation of stopping in emergency, stop the rotation by yarn group for production line for the mode of this ultra-end type unwrapping wire, and arm throwing yarn-discharging device is put the yarn state owing to inertia effect still is in, thereby has guaranteed that cable core does not sustain damage under the situation of stopping in emergency;

4, two covering devices adopt the mode of concentric cross one point bundled, guaranteed cable core therein a yarn occur also can normally tying up under the unexpected situation, improved production efficiency;

5, tensioner is fixed on the end of main shaft, and is conveniently adjusted;

6, two yarn groups are installed simultaneously on the same main shaft, one of them is a standby yarn group, under the situation that yarn group uses up, can in time change, and has guaranteed the production needs of large-size optical cable.
