The invention has the beneficial effects that:

(1) firstly, the vulcanizing pipeline is set to be a vertical structure by arranging the vertical tower, the problem of eccentricity caused by dead weight of a cable is greatly avoided, meanwhile, the self-adaptive mechanism of the invention is coaxially arranged with the vulcanizing pipeline of the cable, and the cable enters from the axis of the vulcanizing pipeline by pulling the rubber extruder during a continuous vulcanizing process, so that the cable can keep better concentricity with the self-adaptive mechanism, and the eccentricity phenomenon generated by the gravity of the cable on the vulcanizing process can be corrected by the first spring and the second spring when passing through the self-adaptive mechanism of the invention, for example, the common cable can be corrected by the dead weight to ensure that the upper part of a cross-linked sheath below a cable conductor is thicker than the upper part, and when the cable is thicker below the cable due to the dead weight in the invention, the sheath layer below receives larger extrusion force, and the second spring below is pulled to deform to weaken the influence of the dead weight of the cable, therefore, the further expansion of the eccentricity of the cable is avoided, the integral eccentricity of the cable is maintained in a small range, and the integral qualification rate of the cable and the performance of a product are improved.

(2) Secondly, self-adaptation mechanism in this application can adapt to the diameter and pass through at the cable of certain size scope, that is to say this application when making the cable of different size specifications in the cable manufacturing process, can both use to when improving the performance of cable product and alleviateing the eccentricity, avoided the process of change with the regulation, thereby improved the manufacturing production efficiency of cable.

(3) Because the cable is in a suspension curve state in the vulcanizing pipe under the action of self weight, the cable is easy to scrape the vulcanizing pipe wall, and the quality problem of the cable surface is caused, in the application, after the coaxiality of the cable and the vulcanizing pipe is reduced, namely, the cable inevitably presses the arc-shaped roller wheels below the cable when passing through the self-adaptive mechanism of the application, so that the arc-shaped roller wheels below the cable are pressed to enable the second springs to generate elastic force, meanwhile, the self-adaptive mechanism is connected through the arc-shaped connecting pieces, after the arc-shaped roller wheels below the cable are pressed to deflect downwards, the first springs of the arc-shaped connecting pieces are compressed to generate tensile force to weaken the trend of downward deflection, and when the cable deflects downwards, namely the cable is not positioned in the center of the device, the cable inevitably presses the arc-shaped roller wheels at two sides, so that the bracket mounting rods at the side of the arc-shaped roller wheels are pressed, and the, namely, the second spring in tension and the first spring in compression work together to avoid the cable from being deflected to generate scraping, so that the problem that the cable is scraped in the vulcanizing tube is greatly reduced.

(4) One section cable conductor after generally starting up can be abandoned because of eccentricity and appearance quality in continuous vulcanization technology, and the finished product rolling is explained at the drum after eccentricity and outward appearance are good, has caused certain waste of material, adopts the device in this application can reduce the extravagant phenomenon of cable of certain degree, makes the cable of vulcanization technology output reach ideal eccentric standard more soon.
