Non-concentric high-speed yarn binding machine with separation of yarn roll center and cable center

Abstract

The invention discloses a non-concentric high-speed yarn binding machine with separation of a yarn roll center and a cable center. A first yarn roll and a second yarn roll are sequentially arranged along an optical cable advancing direction; a first yarn release transmission mechanism and a second yarn release transmission mechanism drive the first yarn roll and the second yarn roll through a transmission device respectively; a tension cylinder drives a tension guide wheel through a driving rod; a yarn binding active mechanism drives a yarn binding mechanism through a driving device; a rolling-up active mechanism drives a rolling-up mechanism through a driving device; and an optical cable advancing channel passes through inner cavities of a first rolling-up mechanism and a second rolling-up mechanism. According to the non-concentric high-speed yarn binding machine with separation of the yarn roll center and the cable center, after twice rolling up of the yarn, the size is greatly reduced, the moment of inertia is reduced, the size and the weight of the yarn binding mechanism are greatly reduced, the rotation speed when the whole machine works can be higher, the yarn binding speed can reach 150 m / min, the working efficiency is higher, the vibration is little, the noise is little, and the yarn roll is convenient to assemble and disassemble.

Description

technical field [0001] The invention belongs to the field of optical cable production equipment, in particular to a non-concentric high-speed yarn binding machine in which the yarn cluster is separated from the center of the cable. Background technique [0002] The production of optical cables is an essential industry in various countries, but due to technical problems, the production quality and production efficiency of optical cables are quite different. Now more than 98% of the domestic cable production lines use the yarn cluster winding mechanism on the binding machine. Adopt aircraft structure. This structure has poor processing accuracy, high noise, high vibration, high risk, and inconvenient installation, low productivity and low speed. The speed of the cable forming machine production line adopting the aircraft structure is all lower than 60m / min. There are two types of yarn binding machines commonly used at present: [0003] The yarn cluster and the cable are not ...

Problems solved by technology

[0003] The yarn cluster and the cable are not concentric, but the yarn cluster and the turntable rotate around the center of the cable. In the yarn binding machine of this structure, the yarn cluster and the turntable are driven by the motor to rotate around the center of the optical cable at the same time. The disadvantage is that the volume of the rotating part and The mass is too large, only suitable for low speed

[0004] Concentric binding machine in which the yarn cluster and the cable rotate concentrically. Both the yarn cluster and the pot rotate around the advancing center of the optical cable, and finally tie the yarn on the optical cable. Limited by the diameter of the yarn cluster, the volume of the pot is large and the moment of inertia is large, 80m The production speed per min is already the highest speed at present, and it is difficult to make a breakthrough. Moreover, because the yarn cluster and the cable are concentric with the yarn binding machine of this structure, it is impossible to change the yarn before the cable is produced. Stored on the cable, this makes the high-speed forward and reverse speed of the twisted front section of the yarn binding also restricted, and the speed cannot be increased
