Through setting toper guide block 7234 to the rotation state, thereby toper guide block 7234 can further ensure the vertical degree of steel wire when the wire winding with the crooked alignment that the steel wire is little when rotating, improve the qualification rate of the steel wire after the wire winding. In this embodiment, an oil storage groove 7236 is further formed at the top of the conical guide block 7234; the elevator tube 7232 is provided with an oil leakage opening communicated with the oil storage tank 7236. Because the steel wire can produce the heat in the alignment process, through steel wire and oil storage tank 7236 contact, heat the antirust oil in oil storage tank 7236, the flow of antirust oil is accelerated to the messenger antirust oil scribbles more evenly.

The oil storage tank 7236 stores rust preventive oil, and the rust preventive oil flows into the oil storage tank 7236 by providing a pipeline for the rust preventive oil on the lift block 722.

In this embodiment, the top of the elevator tube 7232 is provided with a scraping opening 7232a and an arc-shaped storage surface 7232b; a powder guide groove 7237 is formed in the inner wall of the guide tube 7231, and a powder inlet is formed in the inner wall of the guide tube 7231; the powder guide groove 7237 is communicated with the oil storage groove 7236; the scraping opening 7232a is adapted to scrape iron filings from the surface of the wire as it passes through the elevator tube 7232 and into a collection chamber formed by the curved storage surface 7232b and the inner wall of the guide tube 7231; the elevating tube 7232 is adapted to push the iron pieces in the collecting chamber into the powder inlet when it is elevated, and into the powder guide groove 7237 to fall into the oil storage groove 7236, thereby heating the rust preventive oil in the oil storage groove 7236. In a cold state, the scraped powder is used for carrying out secondary heating on the anti-rust oil, so that the anti-rust oil has stronger fluidity, and the anti-rust oil is more uniformly coated. Since the tapered guide blocks 7234 are lifted and rotated while the wire is wound, the powder introduced into the oil reservoir 7236 is rotated, and the heating of the rust preventive oil is made more uniform. Carry out iron fillings through scraping mouthful 7232a and strike off the steel wire that passes the fall-off pipe, the iron fillings that scrape down can the landing on arc storage surface 7232b, when fall-off pipe 7232 along stand pipe 7231 rebound, can upwards promote the iron fillings on the arc storage surface 7232b, and iron fillings can enter into powder guide way 7237 from the powder import landing when passing through the powder import, fall into in the oil storage tank 7236 at last. Simultaneously, because the fall pipe 7232 can be taking place rotatoryly when going up and down to make the iron fillings that are detained on arc storage surface 7232b throw off to the powder import under the effect of centrifugal force, avoid iron fillings to excessively pile up on arc storage surface 7232 b. Moreover, because there is a gap between the inner walls of elevator tube 7232 and the guide tube, there may be iron filings stuck in the gap, therefore, setting elevator tube 7232 to the rotary type, can push the iron filings stuck in the gap upwards, avoid scratching the outer wall of elevator tube and the inner wall of guide tube.
