Description

Automatic collection device and method for inner ends of optical cables Technical Field The invention belongs to the field of optical cable winding facilities, and particularly relates to an automatic collection device and method for an inner end of an optical cable. Background At present, an I-shaped disc is generally adopted by a coiling tool for optical cable winding, the I-shaped disc is provided with two end side plates and a central rotating shaft for connecting the two end side plates, and the central rotating shaft adopts a hollow structure so as to install the I-shaped disc on a cable frame through a tip cone for rewinding or construction paying-off. Referring to fig. 1, in the rewinding or construction paying-off process of the optical cable, the inner end 100 of the optical cable is easy to loosen and throw out, the longer the rewinding or paying-off time is, the more the throwing-out length is, the thrown-out part is generally fixed on the inner side of the end side plate 300 of the spool by adopting the line card 200, frequent stopping treatment is required for the action, the rewinding or construction paying-off efficiency is affected, and the loosening phenomenon is also caused in the high-speed rotating process of the spool by adopting the line card for fixing points, so that the optical cable frequently collides with the side plate of the spool, and finally the inner end of the optical cable is damaged. Disclosure of Invention Aiming at the defects or improvement demands of the prior art, the invention provides an automatic collection device and an automatic collection method for the inner ends of optical cables, which can automatically collect the inner ends of the extended optical cables in rewinding or construction paying-off, so that the inner ends are not easy to damage and the rewinding or construction paying-off efficiency is reduced without frequently stopping and finishing the inner ends.
