Water seepage prevention intermittent ointment filling process

Abstract

The invention discloses a water seepage prevention intermittent ointment filling process, which comprises: S1, controlling an ointment pump to operate through a frequency converter; S2, smearing the ointment on a metal belt through an ointment needle by the ointment pump; S3, scraping off the redundant ointment from the smeared metal belt through a scraping plate; and S4, concentrating the scrapedointment in an oil storage box. According to the invention, a layer of water-blocking cable paste is coated on the surface of a steel belt through simple cable paste coating equipment, so that the steel belt is distorted and formed after passing through a sizing die, and the sprayed water-blocking cable paste is filled in the lap joint position so as to achieve the effect of water seepage prevention, effectively ensure that the metal lap joint position and the cable core are free of water seepage, eliminate the operation of extruding a finished product and coating ointment on the whole cablecore, effectively control the consumption of raw materials and avoid quality accidents caused by resistance to the cable core; and the cable paste coating production process is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of optical cable manufacturing, and in particular relates to an anti-seepage water intermittent oil paste filling process. Background technique [0002] The optical cable is composed of a certain number of combined components in a certain way to form the cable core, and the internal structure is composed of optical fiber, fiber paste, sleeve, PP filling material, water-blocking cable paste, reinforcing element metal belt and outer sheath. Most of the domestically produced optical cable structures use metal strips to wrap the outer sheath as the main production process, and are used to realize a communication line for optical signal transmission. Among them, the water seepage of the optical cable is an important indicator to check whether the finished optical cable is qualified. At present, the main reason for the water seepage of the optical cable is that the metal laps of the optical cable sheath cannot be...

Problems solved by technology

However, various optical cable grease fillings on the market still have various problems

[0003] For example, the authorized announcement number is CN110673284A, a kind of ointment filling process disclosed, although it realizes the process of adjusting the scraper and scraping off the ointment, so that the excess ointment on the surface can be scraped in time after the ointment filling is completed. In order to ensure that the follow-up production and processing can be carried out normally, and avoid the adverse effects caused by excess oil; the soft body setting makes it difficult for the oil in the tube to flow out directly from both ends, thereby slowing down the discharge efficiency of the oil in the tube, thereby reducing the same time. The amount of ointment that needs to be pumped into the interior can achieve the purpose of good energy saving; a good circulation system is formed between the pipe body and the ointment tank. The circulation between the grease tanks will not pollute the grease in the tank. The structure is simple and achieves the purpose of continuously replenishing the pipe body with grease; two different structures of scraping parts are used to realize the redundancy of the surface of the cable core. The full and comprehensive scraping of the ointment has a good scraping effect, but it does not solve the existing problem of not being able to achieve intermittent oiling and reduce the amount of ointment; the thickness cannot be controlled, and the disadvantages of traditional oil-filled ointment overflow cannot be avoided. For this reason, we propose a water-proof intermittent ointment filling process
