By arranging the front rubber layer 422 on the front roller 421 and the rear rubber layer 432 on the rear roller 431, the acting force when the front roller group 42 and the rear roller group 43 clamp the optical cable is flexible acting force rather than rigid acting force, and the optical cable is prevented from being damaged during clamping.
Through arc groove 423 before setting up on preceding rubber layer 422 and set up back arc groove 433 on back rubber layer 432 for the optical cable inlays in arc groove 423 and back arc groove 433 before making effort distribution area when preceding roller set 42 and back roller set 43 centre gripping optical cable increase, better avoid the local concentrated optical cable that leads to of centre gripping effort to damage.
Because the adjacent front rollers 421 are engaged by the front bevel teeth 425 to rotate synchronously, and the rear rollers 431 are engaged by the rear bevel teeth 435 to rotate synchronously, the driving device 44 can realize the linkage of the front roller group 42 and the linkage of the rear roller group 43 only by driving one front roller 421 and one rear roller 431, the structure is simple, and the floor area is reduced.
Because the optical cable passes through the cooling device 3, the strength of the protective material is increased after the optical cable is cooled, and the protective material is prevented from being severely deformed due to stretching when the optical cable is tensioned in the tensioning device 4.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
