Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, in particular to an insulating core isolation agent coating device for a rubber-sheathed cable and a use method thereof. Background Art

[0002] In the cable manufacturing process, coating of the insulating core is one of the key steps. Traditional coating methods include the immersion method, which is to completely immerse the insulating core in the isolating agent solution so that the isolating agent fully penetrates into the surface of the insulation layer and forms a protective film. Although this method can be used for mass production, the uniformity of the coated insulating layer is poor, and it is not possible to apply different thicknesses of insulating layers according to the different conductors. The spraying method is to use a spray gun or spraying equipment to evenly spray the isolating agent on the surface of the insulating core. This method can more accurately control the coating thickness, but the production efficiency is low. The brushing method is to use a brush to brush the isolating agent on the surface of the insulating core. This method has a good coating effect for some cores with complex shapes, but the production efficiency is low. In addition, after the release agent is applied, the wire core needs to be air-dried to ensure that the release agent can be fully dried and form a solid protective film on the surface of the wire core. During the air-drying process, the release agent may flow downward under the action of gravity, resulting in uneven thickness of the protective layer after air-drying, and even the release agent may fall into the air-drying tank, causing blockage and pollution.

[0049] In this embodiment, Figure 2 and Figure 3 , a guide rod 228 is fixedly provided on the coating plate 224;

[0055] In this embodiment, Figure 4 The scraper mechanism 32 includes a second rotating drum 321, a spacer drum 322 and a scraper 323, wherein the second rotating drum 321 is rotatably arranged in the air-drying drum 31, a spacer drum 322 is fixedly arranged in the second rotating drum 321, a plurality of scrapers 323 are circumferentially sealed and slidably arranged on the spacer drum 322, and a clamping rod 324 is fixedly arranged on the scraper 323;

[0058] In addition, the power for the second rotating drum 321 to rotate along the drying drum 31 comes from an external driving mechanism, such as a gear ring mechanism and a worm gear mechanism;

[0059] In this embodiment, Figure 4 and Figure 5 The second rotating drum 321 is provided with a second arc-shaped slot, and a second sealing ring 327 is provided on the outer side of the second rotating drum 321 for sealing rotation. A second hydraulic chamber is formed between the second sealing ring 327 and the second rotating drum 321, and a second through-hole is provided on the second arc-shaped slot, and the second through-hole connects the second hydraulic chamber with the second arc-shaped slot;

[0060] A second sealing block 328 is fixedly provided on the second driving turntable 325 , and the second sealing block 328 slides sealingly along the second arc-shaped slot.

[0061] Correspondingly, the function of the sealing ring 2 327 is the same as that of the sealing ring 1 26, and its purpose is to ensure that the rotation of the driving turntable 2 325 is not affected by the rotation of the rotating cylinder 2 321, that is, to ensure that the scraper mechanism 32 can effectively drive the scraper 323 to retract while scraping the wire core, that is, to stick to the inner wall of the spacer cylinder 322, thereby facilitating the cleaning mechanism 33 to clean it, and the position of the scraper 323 can be adjusted according to different scraping requirements.

[0063] During implementation, the spacer ring 333 extends to the outside of the scraper ring 332 in the initial state, that is, a spacer cavity is formed between it and the spacer cylinder 322, so that the isolation agent scraped off by the scraper ring 332 can fall into this spacer cavity and will not fall on the wire core, that is, it ensures that the isolation agent on the wire core will not be contaminated and disturbed, and ensures the uniformity of the isolation agent after air drying. Then, when the scraper ring 332 slides to the discharge groove 311, the spacer ring 333 slides down into the sliding cavity under the action of the retaining ring 312, that is, the spacer cavity disappears, so that the hanging isolation agent can effectively fall into the discharge groove 311.
