Problems solved by technology
The existing bitumen coating mechanism and coating process mainly have the following problems: 1. The bitumen storage capacity of the bitumen coating mechanism is low, and it is difficult to guarantee the continuous production time of the wire core
2. The asphalt scraping mold is uneven, one is to increase the amount of asphalt used and the production cost, and the other is that after the polypropylene rope is wound, the asphalt will be extruded from the surface of the cable core, which will affect the appearance quality of the core and cause the convection guide wheel Asphalt adheres, increasing the cost of manual post-cleaning
3. The flow rate of the asphalt outlet is small, and the asphalt tank is not closed to produce irritating gas

The submarine cable asphalt coating mechanism comprises a main asphalt cylinder body and an auxiliary asphalt cylinder body, the main asphalt cylinder body and the auxiliary asphalt cylinder body are connected through a connecting pipe, and the main asphalt cylinder body is provided with a rotating wheel, a material conveying opening and an asphalt mold scraping mechanism. The rotating wheel is arranged in the main asphalt cylinder body and provided with a rotating wheel driving mechanism and a rotating wheel lifting mechanism, the conveying opening is formed in the side face of the main asphalt cylinder body, one end of the conveying opening makes contact with the outer side of the rotating wheel, and the other end of the conveying opening is located above the asphalt mold scraping mechanism. The double-cylinder form of the main asphalt cylinder body and the auxiliary asphalt cylinder body is adopted, so that the asphalt storage capacity is improved, a stirring mechanism can be arranged in the auxiliary cylinder body to improve the asphalt melting effect, continuous production of asphalt coating is achieved, and the production quality is improved.
Description
technical field [0001] The invention relates to an asphalt coating mechanism, in particular to a submarine cable asphalt coating mechanism, which belongs to the technical field of submarine cable production. Background technique [0002] In the manufacturing process of submarine cables, armored wires are required for mechanical protection. After armoring, they need to be coated with asphalt. The main function of coating the surface of armored wires with asphalt is to protect the armored wires from seawater corrosion, ensuring Steel wire has corresponding mechanical properties. The asphalt coating process is an indispensable process in the submarine cable production process. When the submarine cable is running on the seabed, it will be affected by external machinery (the impact of ocean currents and sandstones), erosion of marine microorganisms, seawater and hydrogen sulfide, etc. Corrosion will reduce the service life of the submarine cable. In order to maximize the service...
