Abstract
Description
Technical Field
[0001] The invention relates to the field of machinery, in particular to an optical fiber grease coating leakage prevention device. Background Art
[0002] During the manufacturing process of communication optical cables, fiber optic grease is applied to the gaps between the cables and the fibers to prevent moisture intrusion and damage from friction during the manufacturing process. This ensures good mechanical properties and extends the service life of the fibers. When the optical cable is armored with steel or aluminum tape, a continuous layer of heat-melting solid glue or water-swelling water-blocking grease is applied to the joints to improve the cable's water resistance.

[0042] In operation, the metal strip passes through the support and positioning mechanisms before entering directly below the coating mechanism 5. The oil reservoir sprays the grease evenly onto the metal strip's surface via the spray plate. The strip then enters the extrusion and leak-proof mechanism. The diagonal extrusion plate squeezes some of the grease applied to the strip's edges into the strip's interior, creating a seamless coating of the grease within the strip. Simultaneously, some grease falls through the gap between the vertical plate and the strip into the collection trough 48. A negative pressure suction pipe at the bottom of the collection trough 48 removes any remaining grease. As the strip continues forward, the grease accumulated on the strip's interior is flattened by the diagonal pressure plate. Simultaneously, the diagonal negative pressure pipe removes any grease accumulated on the diagonal extrusion plate, completing the grease coating process while preventing uneven application and spillage.
