Background technique

Generally, common cables such as optical cables are generally stranded through multiple optical cable cores, specifically such as SZ stranded, that is, stranded with continuously changing helical directions, and yarns are tied on the outside of the optical cable cores. Among them, the optical cable core generally includes a loose tube and optical fibers and fiber paste arranged in the loose tube. A strengthening member is arranged in the middle of the optical cable core. A plurality of optical cable cores, sometimes with the help of a filling rope, can evenly surround the strengthening member. outside. On the outer side of the optical cable core, two binding yarns with different rotation directions are generally required to wrap around the outer side of the cable.

Fig. 1 is a structural schematic diagram of a common cable tie device in the prior art. It specifically includes the aircraft 101 and the support base 102. The aircraft 101, the yarn reel 103 and the support base 102 are sequentially sleeved on the harness tube. Here and below, the end with the support base 102 is called the rear end. The loading end is the front end. It is also provided with a rotating transmission shaft and a wire-releasing transmission shaft, both of which are supported by the support seat 101 and are sequentially sleeved on the outside of the wire harness from the inside to the outside.

It should be noted here that the front end of the pay-off drive shaft 10 refers to the moving-in end of the yarn roll , the other end is the backend. Among them, the pay-off drive shaft 10 is used to support the yarn reel 1, and is generally fixed relatively to the yarn reel 1 by means of expansion, and a pay-off motor 6 is generally provided, and the pay-off motor 6 is mainly used to drive the pay-off drive The shaft 10 rotates so that the binding yarn reel 1 can be unwound to avoid twisting the binding yarn. The rotation of the pay-off drive shaft 10 is generally driven by the pay-off motor 6, and the specific driving method can refer to the prior art. The yarn binding assembly should also include an aircraft 4 for driving the binding yarn to be wound on the outside of the cable 5 , generally including a rotating transmission shaft 9 and a rotating motor 7 .

The spare binding yarn storage device 3 is used to store the spare binding yarn. It should be noted here that, for the convenience of description, the binding yarn roll 1 arranged on the spare binding yarn storage device 3 is called the spare binding yarn. Wherein the spare binding yarn storage device 3 is relatively fixed with the support base 2, thereby avoiding placing the spare binding yarn on the pay-off drive shaft 10 and avoiding the excessive length of the pay-off drive shaft 10. It should be noted here that when When the spare yarn binding storage device 3 is set, it should be ensured that the yarn binding roll 1 arranged on the standby yarn binding storage device 3 can move from the front end of the pay-off drive shaft 10 to the binding position of the cable 5 during the yarn binding of the cable 5 . On the transmission shaft of the yarn reel 1, especially for the installation of the aircraft 4, it should avoid interfering with the loading of the spare binding yarn. The specific settings of the aircraft 4 can be referred to below. In order to facilitate the assembly of spare yarn binding, the spare yarn binding storage device 3 should be arranged on the front side of the yarn binding device, that is, the side away from the support base 2, and the spare yarn binding storage device 3 should be able to store the yarn binding. The specific backup binding yarn storage device 3 may be provided with a support tube coaxially arranged with the pay-off drive shaft 10 and a support platform for supporting the support tube. Wherein the supporting platform should support the supporting tube from an end away from the pay-off drive shaft 10 on the support tube, so as to avoid the support platform from interfering with the spare binding yarn and moving to the loading end of the binding yarn roll 1 of the pay-off transmission shaft 10 . Wherein, in order to ensure the length of one tying yarn, each spare tying yarn storage device 3 can be provided with at least two spare tying yarn storage positions, and one spare tying yarn storage position is used to store a spare tying yarn.

In this embodiment, when using the cable tying device, a plurality of spare tying yarns can be set on the spare tying yarn storage device 3 according to needs. The spare binding yarn loaded on the transmission shaft 10 is limited, while avoiding the excessive length of the pay-off transmission shaft 10 and jumping, thereby effectively improving the service life. Therefore, the cable binding device 4 is independently provided with a spare binding yarn storage device 3 by breaking away from the pay-off transmission shaft 10, thereby avoiding that the spare binding yarn is also pre-installed on the pay-off transmission shaft 10, and then can effectively solve the problem of thread binding.

Wherein aircraft 4 generally can be provided with conduit 12, and conduit 12 rotates around the axis of cable 5, to drive yarn to be wound on cable 5, and the rotation driving part of guide tube 12 is that rotating transmission shaft 9 can be large circle. At this time, the aircraft 4 is arranged on the inner side of the large cylinder, and the cylinder and the cable 5 are arranged coaxially, and are driven to rotate by the rotating motor 7 . This time, it will cause a relatively large occupied space. Based on this, the rotary transmission shaft 9 can be arranged on the inside of the pay-off transmission shaft 10, and the aircraft 4 is detachably connected to the rotary transmission shaft 9, which is now used to drive the rotary transmission shaft 9. The rotating rotary motor 7 can be installed on the rear end of the support base 2 to drive the rotary transmission shaft 9 to rotate, and in order to prevent the aircraft 4 from interfering with the setting of the pay-off motor, the aircraft 4 should be arranged at the front end of the pay-off transmission shaft 10 at this time . What needs to be explained here is that no matter what the installation position of the aircraft 4 is at this time, it should ensure that the aircraft 4 can be separated from the cables in the yarn binding, that is, when the cables pass over the aircraft 4, the aircraft 4 should not be fully sleeved. A loop at the outer end of the cable so that the aircraft can be completely removed from the path of the spare tying when the spare tying is installed. Specifically in use, after the yarn binding on the binding yarn roll 1 is used up, the aircraft 4 is removed from the rotating transmission shaft 9, and the aircraft 4 is disengaged from the moving position of the standby yarn binding, so that the binding yarn roll 1 is loaded into the entrance When the aircraft 4 blocks it again, the backup yarn close to the backup yarn storage device 3 is moved along the cable 5 to the pay-off transmission shaft 10 and installed, and then loaded into the aircraft 4, the next winding can be performed. Binding yarn for roll 1.

Specifically, both the first flying part and the second flying part may include a support rod 11 fixedly connected to the rotating transmission shaft 9, and a wire guide 12 extending along the extension direction of the cable 5. It should be noted here that according to the According to the principle of yarn, the extension direction of the cable 5 should be consistent with the extension direction of the rotary transmission shaft 9 and be arranged coaxially.

Wherein the detachable connection between the aircraft 4 and the rotating drive shaft 9 can be clamping, or screw 8 connection, or bolt connection, considering the limitation of the diameter of the inner hole of the binding yarn roll 1, preferably The screw 8 is connected, specifically, the first flying part and the second flying part can be respectively connected with the rotating transmission shaft 9 through the screw 8, and the screw 8 is extended along the extension direction of the cable 5, because the axial space of the transmission shaft of the aircraft 4 Many, and then the restriction on the size of the screw 8 will be relatively small.

Simultaneously, in order to make the two flying parts of the aircraft 4 install more firmly, and considering the connecting short plate of the connecting screw 8, a front end portion of the rotating transmission shaft 9 can be provided with the first flying part to be inserted along the direction perpendicular to the extension of the screw 8. The first slot connected with the second flying part and the second slot plugged with the second flying part along the direction perpendicular to the extension of the screw 8, the movement of each flying part along the axial direction is restricted by the groove walls on both sides of the slot. At the same time, it is preferable to make the first flying part abut against the groove bottom of the first slot, and the second flying part abut against the groove bottom of the second slot, so as to limit the radial direction.

In order to improve the yarn binding efficiency, when it is necessary to perform two binding yarns on one cable 5, such as a common SZ type optical cable, it is necessary to use two binding yarns to wrap the yarns in different directions. In order to improve production efficiency, two yarn binding assemblies can be set, and each yarn binding assembly should include a pay-off transmission shaft 10, a support seat 2, a rotating transmission shaft 9, and an aircraft 4, and the two yarn binding assemblies should all be provided with corresponding spare parts. Binding yarn storage device 3. When the winding directions are different, the rotation directions of the aircraft 4 of the two yarn binding assemblies should also be different. What needs to be emphasized at this time is that the relative positional relationship of the two yarn binding assemblies should not interfere with each other and the spare yarn binding storage device 3 moves to the wire-feeding drive shaft 10 of the respective yarn binding assembly. Specifically, when two yarn binding assemblies are arranged oppositely, that is, when the front ends of the two pay-off transmission shafts 10 are close to each other, the respective backup yarn binding storage devices 3 can be arranged in the middle of the two yarn binding assemblies. The yarn binding points of the yarn components are respectively arranged between the yarn binding components and their corresponding standby yarn binding storage devices 3 . It can also be that two yarn binding devices are arranged opposite to each other, that is, when the front ends of two pay-off drive shafts 10 are close together, the supporting bases 2 of the two yarn binding devices are arranged close to each other at this moment. In order to make the installation of the yarn binding device compact and convenient for centralized control, it is preferred that the two yarn binding assemblies are arranged opposite to each other here.

Each embodiment in this specification is described in a progressive manner, each embodiment focuses on the difference from other embodiments, and the same and similar parts of each embodiment can be referred to each other.

The above description of the disclosed embodiments enables those skilled in the art to realize or use the utility model.
