Background

In the cable manufacturing industry of optical cables, cables and the like, the eccentric stranding machine is generally used for producing cables, and the cables produced by the eccentric stranding machine are spiral in a natural state, so that the cable is easy to knot, and the cable is inconvenient to use in a later period. The existing cable traction device consists of an incoming traction wheel and an outgoing traction wheel which are opposite in rotation direction, and cables are alternately wound in a plurality of wire grooves on the incoming traction wheel and the outgoing traction wheel to form a 8 shape, so that the cables are frequently bent to two sides of the cable traction device in a direction changing manner in the transmission process through the incoming traction wheel and the outgoing traction wheel, namely, the cables are bent inwards and outwards, and the cables are directly discharged from the spiral cable stranding machine.

However, in the existing traction device, the intervals between the wire grooves of the wire inlet traction wheel and the wire grooves of the wire outlet traction wheel of the traction wheel set are not reasonably set, so that when the wire is transited from the wire groove on the wire inlet traction wheel or the wire outlet traction wheel to the wire outlet traction wheel or the next wire groove on the wire inlet traction wheel, the wire is not uniformly inclined by a certain angle, and the adjacent transiting wires are easily worn mutually, so that the surface quality of the wire is poor.

In addition, the existing cable traction device only has a pair of traction wheels, straightening can be achieved after the spiral PVC cable is drawn, but for a low-smoke zero-halogen cable (the low-smoke zero-halogen cable is made of a sizing material which does not contain halogen, lead, cadmium, chromium, mercury and other environmental substances, and the like), the low-smoke zero-halogen cable cannot emit toxic smoke during combustion, the flame retardant performance of the low-smoke zero-halogen cable is excellent, the smoke degree during combustion is very low, no corrosive gas escapes, and the low-smoke zero-halogen cable is widely used at present), and because the low-smoke zero-halogen cable has high hardness, the existing traction device cannot straighten the low-smoke zero-halogen cable.

Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.

The core of the application is to provide a cable traction device and an eccentric cable stranding machine.

In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.

As shown in fig. 1-5, the present application is embodied to provide a cable pulling device. The cable traction device according to the embodiment of the application comprises a plurality of pairs of traction wheel sets 1 and a driving part 2, wherein the pairs of traction wheel sets 1 are arranged at intervals. Specifically, the traction wheel set 1 comprises an incoming traction wheel 11 and an outgoing traction wheel 12, the incoming traction wheel 11 and the outgoing traction wheel 12 are arranged at intervals, and the axis of the incoming traction wheel 11 is parallel to the axis of the outgoing traction wheel 12. The cylindrical surface of each of the incoming wire traction wheel 11 and the outgoing wire traction wheel 12 is provided with a plurality of wire grooves 13 for winding cables at intervals along the axial direction, and the wire grooves 13 of the incoming wire traction wheel 11 and the wire grooves 13 of the outgoing wire traction wheel 12 are in one-to-one correspondence and are staggered by half of a wire groove along the axial direction in sequence. That is, any one of the wire grooves 13 of the wire-incoming traction wheel 11 and the corresponding wire groove 13 of the wire-outgoing traction wheel 12 are arranged with a half of the wire grooves staggered in the axial direction. The axis direction is the center line direction of the wire pulling wheel 11 and the wire pulling wheel 12.

Therefore, when the cable 3 is transited from the wire inlet traction wheel 11 or the wire outlet traction wheel 12 to the wire outlet traction wheel 12 or the corresponding wire outlet traction wheel 11, and when the cable 3 is transited from the wire inlet traction wheel 11 or the wire outlet traction wheel 12 to the wire outlet traction wheel 12 or the wire outlet traction wheel 11, the cable 3 can be inclined at a certain angle relatively, so that the distance between the adjacent transition cables 3 is increased, the mutual abrasion between the adjacent transition cables 3 is avoided, and the surface quality of the cable 3 is ensured.

Correspondingly, if the wire grooves 13 corresponding to the wire inlet traction wheels 11 and the wire outlet traction wheels 12 one by one are not staggered by half grooves along the axis direction and are opposite or nearly opposite, when the wire 3 transits from the wire groove on the wire inlet traction wheels 11 or the wire outlet traction wheels 12 to the wire outlet traction wheels 12 or the wire groove on the wire inlet traction wheels 11 corresponding to the wire outlet traction wheels next, the transition wire is almost perpendicular to the axis, so that the distance between the adjacent transition wires is reduced, the adjacent transition wires are worn mutually, and the surface quality of the wire is reduced.

It should be noted that, since the incoming wire traction wheel 11 or the outgoing wire traction wheel 12 are all cantilever-arranged outside the machine housing, in order to make the axial direction of the incoming wire traction wheel 11 or the outgoing wire traction wheel 12 with a certain number of wire slots as small as possible, so as to reduce the requirement on the bearing, the distance between adjacent wire slots is smaller than the width of the wire slots.

The driving part is used for driving the incoming line traction wheel 11 and the outgoing line traction wheel 12 to rotate and enabling the rotation directions of the incoming line traction wheel 11 and the outgoing line traction wheel 12 to be opposite. The cables sequentially bypass the plurality of pairs of traction wheel groups, and are sequentially and alternately wound in a plurality of wire grooves of the wire inlet traction wheels 11 and a plurality of wire grooves 13 on the wire outlet traction wheels 12 of the traction wheel groups, so that the wires on the wire inlet traction wheels 11 and the wire outlet traction wheels 12 of the traction wheel groups 1 are 8-shaped. So that the cable 3 can be straightened in sequence over a plurality of pairs of traction sheave sets 1.

For the low-smoke halogen-free cable with larger hardness, the low-smoke halogen-free cable is continuously straightened by adopting the plurality of pairs of traction wheel sets 1, so that the straightening effect is better than that of increasing the number of the wire grooves 13 of the wire inlet traction wheels 11 and the number of the wire grooves 13 of the wire outlet traction wheels 12, and the straightening requirement of the low-smoke halogen-free cable is met. On one hand, the number of the wire grooves 13 is increased too much, the requirement on the supporting strength of the bearings for supporting the wire inlet traction wheel 11 and the wire outlet traction wheel 12 is higher, and on the other hand, the rigidity of the rotating shafts of the wire inlet traction wheel 11 and the wire outlet traction wheel 12 with increased lengths is influenced, so that the traction effect of the wire inlet traction wheel 11 and the wire outlet traction wheel 12 on the wire 3 is reduced.

Therefore, the cable traction device has the advantages of avoiding mutual abrasion between adjacent transition cables and straightening cables with larger hardness.

Based on the above embodiment, the pairs of traction wheel sets 1 are arranged at intervals in the horizontal direction. The arrangement makes the cable 3 through a plurality of pairs of traction wheel sets 1 and the height change of the cable 3 after passing through a pair of traction wheel sets 1 consistent, and after the cable traction device is added with the traction wheel sets 1, an operator can conveniently wind the cable to the incoming traction wheel 11 and the outgoing traction wheel 12 and observe the operation of the traction wheel sets 1. On the other hand, the maintenance of the traction wheel sets 1 by operators is also facilitated.

Based on the above embodiment, the traction sheave groups 11 are preferably arranged in two or three pairs. Two or three pairs of traction wheel sets 1 can meet the common cable traction requirement.

Based on the above embodiment, when the traction wheel set 1 is provided in two pairs, the driving part 2 includes the motor 21, the first gear 22, the second gear 23, the third gear 24, and the fourth gear 25. The motor 21 is in transmission connection with the first gear 22, the first gear 22 is respectively in meshed connection with the second gear 23 and the third gear 24, and the fourth gear 25 is respectively in meshed connection with the second gear 23 and the third gear 24.

The first gear 22 and the second gear 23 are in one-to-one transmission connection with the incoming line traction wheel 11 and the outgoing line traction wheel 12 of the first pair of traction wheel sets 1, and the third gear 24 and the fourth gear 25 are in one-to-one transmission connection with the incoming line traction wheel 11 and the outgoing line traction wheel 12 of the second pair of traction wheel sets 1. In this case, two pairs of traction wheel sets 1 are arranged at intervals in the horizontal direction. Or, the first gear 22 and the third gear 24 are in one-to-one transmission connection with the incoming line traction wheel 11 and the outgoing line traction wheel 12 of the first pair of traction wheel sets 1, and the second gear 23 and the fourth gear 25 are in one-to-one transmission connection with the incoming line traction wheel 11 and the outgoing line traction wheel 12 of the second pair of traction wheel sets 1. In this case, two pairs of traction wheel sets 1 are spaced apart in the up-down direction. The up-down aspect is the up-down direction of the machine placement.

Therefore, the cable traction device in the embodiment of the present application drives the first gear 22 to rotate only through one motor 21, the first gear 22 drives the second gear 23 and the third gear 24 to rotate, and the second gear 23 and the third gear 24 drive the fourth gear 25 to rotate. In other words, the rotation of all gears is driven by one motor 21, so that the rotation speeds of all gears are consistent in height, the problem that the traction effect of the cable 3 is poor due to speed mismatch among a plurality of pairs of traction wheel sets 1 is avoided, and the traction straightening effect of the cable 3 is better.

Based on the above embodiment, when the traction sheave assembly 1 is provided as three pairs, the driving portion 2 includes the motor 21, the first gear 22, the second gear 23, the third gear 24, the fourth gear 25, the fifth gear 26, and the sixth gear 27, the motor 21 is in driving connection with the first gear 22, the first gear 22 is in meshed connection with the second gear 23 and the third gear 24, respectively, the fourth gear 25 is in meshed connection with the second gear 23, the third gear 24, and the sixth gear 27, respectively, and the fifth gear 26 is in meshed connection with the third gear 24 and the sixth gear 27, respectively.

The first gear 22 and the second gear 23 are in one-to-one transmission connection with the incoming line traction wheel 11 and the outgoing line traction wheel 12 of the first pair of traction wheel sets 1, the third gear 24 and the fourth gear 25 are in one-to-one transmission connection with the incoming line traction wheel 11 and the outgoing line traction wheel 12 of the second pair of traction wheel sets 1, and the fifth gear 26 and the sixth gear 27 are in one-to-one transmission connection with the incoming line traction wheel 11 and the outgoing line traction wheel 12 of the third pair of traction wheel sets 1. At this time, three pairs of traction wheel sets 1 are arranged at intervals in the horizontal direction.

In the same way, when three pairs of traction wheel sets 1 are provided, the cable traction device in the embodiment of the application drives the first gear 22 to rotate only through one motor, the first gear 22 drives the second gear 23 and the third gear 24 to rotate, the second gear 23 and the third gear 24 drive the fourth gear 25 to rotate, the third gear 24 also drives the fifth gear 26 to rotate, and the fifth gear 26 and the fourth gear 25 drive the sixth gear 27 to rotate. In other words, the rotation of all gears is driven by one motor 21, so that the rotation speeds of all gears are consistent in height, the problem that the cable traction 3 is poor in effect due to speed mismatch among a plurality of pairs of traction wheel sets 1 is avoided, and the cable 3 is better in traction straightening effect.

Based on the above embodiment, the number of the wire grooves 13 of each of the incoming wire traction wheel 11 and the outgoing wire traction wheel 12 is equal to or less than 8. So as to avoid overlong axial length of the incoming line traction wheel 11 and the outgoing line traction wheel 12, and worsen the bearing stress condition of the supporting incoming line traction wheel 11 and the outgoing line traction wheel 12.

Based on the above embodiment, the bottom of the wire groove 13 is set to be arc-shaped, and the edge of the wire groove 13 is set to be rounded, so that the abrasion of the cable 3 can be avoided.

Based on the above embodiment, the interval between the incoming wire traction wheel 11 and the outgoing wire traction wheel 12 of each pair of traction wheel sets 1 is 45mm-55mm, the interval is slightly smaller than the diameters of the incoming wire traction wheel 11 and the outgoing wire traction wheel 12, and the interval can ensure the better straightening effect of the cable 3.

Based on the above embodiment, the width of the wire groove 13 is at least 3mm wider than the width of the cable 3, so that the cable 3 can be prevented from being caught in the wire groove 13.

The embodiment of the application also provides an eccentric cable stranding machine, which comprises any one of the cable traction devices. The embodiment of the application also provides an eccentric cable stranding machine effect which is the same as the cable traction device.
