Abstract

The invention discloses a special traction device for a high-speed optical fiber secondary coating production line. The special traction device comprises a stand column; the stand column is equipped with a translation mechanism; the translation mechanism comprises a guide rail; a translation motor is installed at the lower side of one end of the guide rail; the translation motor is equipped with achain wheel in a drive mode, and the chain wheel is located at the inside of one end of the guide rail; a tensioning wheel is installed at the inside of the other end of the guide rail, and the tensioning wheel and the chain wheel are driven by a chain; the chain is equipped with a pulley, and the pulley is slidably arranged on the upper side of the guide rail; the upper side of the pulley is equipped with a lifting motor; and a traction mechanism is installed at one side of the bottom of the lifting motor. The traction device of the scheme can realize the use of an elastic stretching processto generate the optical fiber extra length, which is beneficial to improve the production speed of optical fiber coating and accurately control the optical fiber extra length in a PBT sleeve, so thatthe crystallization speed of the optical fiber sleeve is improved, the retraction is reduced, and the optical fiber extra length is more stable.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a special traction device for a high-speed optical fiber secondary coating production line. Background technique [0002] In the optical cable manufacturing process, the second coating production process of optical fiber is a key process, and the precise control of the excess length of optical fiber in the loose tube is the key point of technology. At present, with the continuous development and progress of my country's optical cable manufacturing equipment and process technology, the operating speed of the optical fiber secondary coating production line has increased from the original 250mpm to the current 600mpm, and some have developed a 800mpm production line, but the optical fiber in the casing There is still a certain gap in the precise control and uniform stability of the excess length. Contents of the invention [0003] The object of the present invention is to s...
