The working principle is as follows:

starting a motor, driving a first coating roller 11 and a second coating roller 13 to rotate inwards under the mutual matching of the meshing action of a first rotating gear 4 and a second rotating gear 5 and the transmission action of a first belt pulley 7, a transmission belt 8 and a second belt pulley 9, placing an optical fiber strip 14 in the middle of the inner sides of the second coating roller 13 and the first coating roller 11, when the first coating roller 11 and the second coating roller 13 rotate, abutting the outer walls of the first coating roller 11 and the second coating roller 13 against the outer wall of the bottom end of an inner coating brush 20 to finish coating the outer walls of the first coating roller 11 and the second coating roller 13, and driving two groups of coating brushes 20 arranged on the outer wall of a third fixed rotating rod 16 to alternatively rotate under the action of bearings on two sides of the third fixed rotating rod 16 to enable the top ends of the outer coating brushes 20 to contact with the coating stored in a coating plate groove 27, so that the coating material flows onto the outer wall of the coating brush 20 by the pressing action of the pressing plate 32, and this operation is ended.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
