Spraying system for ointment coating of optical fiber and cable

Abstract

The invention discloses a gel application spraying system for optical fiber cables. The gel application spraying system comprises a longitudinal covering rack, a support, a gel storage tank, a spray head mechanism and a supporting mechanism. Two x-direction linear rails are fixed on the surface of a base table of the support and are embedded into grooves of x-direction sliders fixed on the lower surface of a carrying plate, the spray head mechanism is mounted on the carrying plate and comprises a gel storage chamber, one end of the gel storage chamber is connected to a first port of a tee joint, a second port and a third port of the tee joint are connected with a gel inlet pipe and a pressure gauge respectively, and the other end of the gel storage chamber is connected with a gel nozzle. A supporting rod and the supporting mechanism are positioned on two sides of the gel nozzle and below the gel nozzle, so that metal strip conveying passages are formed between the gel nozzle and the supporting rod as well as between the gel nozzle and the supporting mechanism. The supporting mechanism comprises a left side plate, a right side plate, an oval shaft sleeve, a guide wheel and a positioning mechanism, wherein the oval shaft sleeve is positioned between the left side plate and the right side plate. The gel application spraying system for the optical fiber cables is capable of controlling gel applying amount and capable of adjusting the positions of a spray head and metal strips conveniently so as to guarantee spraying position accuracy.

Description

technical field [0001] The invention relates to the field of ointment spraying during optical fiber cable manufacturing, in particular to a spraying system for optical fiber cable ointment coating. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications, using one or more optical fibers placed in a sheath as a transmission medium, and used individually or in groups. Communication cable assemblies. The optical cable is generally composed of several parts such as a cable core, a reinforced steel wire, a filler, and a sheath. In addition, there are components such as a waterproof layer, a buffer layer, and an insulated metal wire as required. [0003] During the long-term use of the optical cable, due to the infiltration of moisture and moisture, the transmission performance of the optical cable will be deteriorated, and it may even be unusable. In the preparation process of communication optical cab...

Problems solved by technology

However, in actual production, it is difficult to achieve the best position and quantity of hot melt adhesive or water-blocking ointment applied to the edge of the metal strip.

In order to ensure sealing during production, only increase the amount of application, the result is that the grease overflows when wrapping the steel / aluminum strip longitudinally, which is not conducive to production
