Among them, ADSS, indoor optical cables, flame retardant optical cables and other sheathed optical cables have good waterproof, anti-external force, flame retardant, etc. Advantages, can be used in coal mines, indoor communications and other fields.

Due to customer requirements, during the processing of the sheathed optical cable, it is necessary to print fonts on the surface of the outermost sheath to display manufacturer information, production meters and other information. However, in actual production, due to cable body jitter, printer failure, unclean water blowing, etc., the produced sheathed optical cable will have problems such as unclear typing, large optical loss, obvious test steps, and cable collapse. , thus forming a problem cable. Except for some problem cables that cannot be reused due to optical fiber breakage, appearance deformation and other factors, other problematic cables can also be reused after being effectively rewound or re-typed to reduce waste of resources and economic losses.

For the cable to be re-typed, the existing printing on the cable needs to be removed before typing. According to the investigation, the existing method for removing the printing on the surface of the sheathed optical cable is usually to wipe with a solvent (cleaning agent or acetone solution) manually. This method is not only inefficient and slow, but also the solvent stays on the surface of the sheathed optical cable for a long time. Long, it is easy to corrode the outer sheath, causing irreparable damage. Therefore, there is an urgent need to design an optical cable automatic word removing device and a method for realizing the same.

working principle:

The principle of meter counting is as follows: the protrusions set on the meter wheel 14 will be captured by the speed sensor 16 once every one rotation to form a high-level pulse signal, and the interval between two adjacent high-level pulse signals is the meter wheel. The time it takes for 14 to rotate once, and the circumference of the circular surface of the meter wheel 14 is fixed at 500mm, to ensure that the meter wheel 14 rotates for two weeks, and the sheathed optical cable 13 advances one meter; after the time and displacement signals are calculated and processed by the TMS32028335 main control chip, The advancing speed of the sheathed optical cable 13 can be obtained.

Word removal process: Since the jacket type optical cable 13 is printed by meter, when the word is removed, under the control of the TMS32028335 main control chip, the meter wheel 14 rotates every two turns to turn on the pumping motor 3, and the return box 6 is turned on. After the solvent placed inside is sucked into the spray tube 701, it is sprayed onto the sheath of the advancing sheathed optical cable 13 by three annular nozzles 7, and the injection time is fixed at two seconds. However, the sheathed optical cable 13 runs at a low speed and a uniform speed during rewinding, and two seconds is enough to remove the long printed characters. This design can ensure that the non-printed parts are not contaminated with solvent and reduce the erosion area; after the sprayed solvent passes through the filter screen 203 It will automatically drop into the return box 6 and can be reused. The impurities and foam filtered by the filter screen 203 can be taken out through the outer door 201; The first-grade wiping towel 11 can wipe off the solvent remaining on the sheath of the sheathed optical cable 13. The first-grade wiping towel 10 and the second-grade wiping towel 11 need to be replaced and cleaned frequently, and the solvent dripping from the wiping box 9 passes through the connecting pipe 12 flows into the spray washing box 2, and enters the reflux box 6 after filtering; when the solvent is insufficient, it can be added through the feeding port 601.
