Portable small-tension yarn winding machine for large-core-number high-density micro-cluster optical cable

Abstract

The invention discloses a portable small-tension yarn winding machine for a large-core-number high-density micro-cluster optical cable, wherein the machine comprises a rack, a motor, a supporting sleeve, a central hollow pipe, a first bearing, a movable ring mold seat, a yarn drum shaft sleeve, a guide mold, a flying shuttle and a yarn guide pipe; the central hollow pipe is rotatably mounted on the inner side of the supporting sleeve through the first bearing; the motor is connected with the first end of the central hollow pipe through a transmission mechanism, the movable ring mold seat is mounted at the second end of the central hollow pipe, and the guide mold is mounted on the movable ring mold seat; the yarn drum shaft sleeve is rotatably mounted on the outer side of the supporting sleeve through a second bearing; the flying shuttle is fixedly mounted on the movable ring mold seat; and the yarn guide tube is fixedly arranged on the flying shuttle. The rotating resistance torque of the second bearing can be converted into the product of yarn winding tension and the force arm from the outer diameter of a yarn roll to the central hollow pipe, the maximum yarn winding tension is small, the maximum value and the minimum value of the yarn winding force value are controllable, control is safe, the situation that a micro-cluster pipe or an optical fiber is damaged by tying cannot occur, and the yarn winding machine is reliable.

Description

technical field [0001] The invention belongs to the field of optical cables, and more specifically relates to a portable small-tension yarn winding machine for large-core high-density micro-cluster optical cables. Background technique [0002] With the rapid development of 5G network construction, in order to save scarce tube hole resources, large-core high-density micro-cluster optical cables are becoming more and more popular. For example, in the optical cables used on the Hong Kong-Zhuhai-Macao Bridge, the number of optical fiber cores has reached 1152 cores. , Some data centers use a single fiber optic cable with 3456 cores, and in foreign applications, a single fiber optic cable even reaches more than 10,000 cores. Since each ferrule holds 12 optical fibers, the number of ferrules in a high-core-count optical cable may reach hundreds, and how to manage and identify these ferrules becomes a difficult problem. [0003] At present, the conventional method is to carry out ...

AI Technical Summary

Problems solved by technology

At present, the yarn winding equipment on the market is either directly dragged and dropped without pitch adjustment, or is a very clumsy and bulky large-scale yarn binding machine that can adjust the pitch, covering an area of ​​1m. 2 -1.5m 2 , volume up to 2m 3 -3m 3 , and the weight is generally more than 1000kg. These tying machines with adjustable pitch all use electromagnetic clutch to control the tying tension. Some tying tensions are as high as 700g. Reduced to about 200g, but because the tension control method of the electromagnetic clutch will be affected by the speed up and down, the control current fluctuation itself brings about a very large change in the binding tension, and the optical fiber in the micro-cluster tube is often strangled during production, resulting in greater attenuation of the optical fiber Phenomenon

[0006] At the same time, for the production of high-density micro-cluster optical cables with large cores, in order to improve production efficiency, it is often necessary to group many casings and wind them at the same time to identify them and form cables or sheaths together. If the size of the winding equipment is too large, it will interfere with the running of each group of casings. The path requires a lot of space for equipment placement. In addition, the existing binding machines that can adjust the pitch weigh more than a ton. It requires a forklift to move, which is extremely unsuitable for multiple sets of casings. use simultaneously
