Online reeling device for amorphous ribbon

Abstract

The invention provides an online reeling device for an amorphous ribbon. The device comprises a first reeling shaft, a second reeling shaft, a rotary platform and a working platform. The first reeling shaft and the second reeling shaft are respectively arranged at two sides of the rotary platform of the working platform. The first reeling shaft and the second reeling shaft are respectively provided with a first reeling cylinder and a second reeling cylinder. The first reeling cylinder is located on a reeling station and reels the amorphous ribbon through negative pressure. After the amorphous ribbon is fully reeled, the amorphous ribbon is broken through a breaking shear. A reeling platform rotates 180 degrees. After the second reeling cylinder arrives at the reeling station, working steps of the first reeling cylinder are repeated. When the second reeling cylinder reels the amorphous ribbon, the first reeling cylinder unloads the ribbon, a hollow reeling cylinder is assembled and prepares for reeling the amorphous ribbon and continuous grabbing of the amorphous ribbon is achieved. The online reeling device for the amorphous ribbon is particularly suitable for online automatic reeling of the mass produced amorphous ribbon in industry.

Description

technical field [0001] The invention relates to the field of manufacturing amorphous strips, in particular to an online coiling device for amorphous strips. Background technique [0002] When preparing amorphous thin strips, molten steel is sprayed from nozzles onto high-speed rotating crystallization rollers, and instantly solidifies into thin strips with a thickness of 25-30 μm, and the strip-out speed is 20-30 m / s. Usually only the coiled strip can be formed into a product. In view of the characteristics of thin thickness and fast stripping speed of the amorphous strip, the more effective grabbing method is to use negative pressure grabbing, that is, use a negative pressure take-up drum close to the crystallization roller to make the strip adsorb to the take-up drum , and then coiled. Because this method requires the take-up drum to be a hollow structure, and the take-up drum is usually pressed against the take-up shaft by the conical surfaces on both sides of the take-...

AI Technical Summary

Problems solved by technology

Because this method requires the take-up drum to be a hollow structure, and the take-up drum is usually pressed against the take-up shaft by the conical surfaces on both sides of the take-up drum, the loading and unloading of the coil is time-consuming, and because it can only be mounted on one coil For coiling, continuous operation and mass production with limited strip grabbing

In addition, the Chinese patent (96212128.2) introduces a winding mechanism capable of continuous grabbing with double winding drums, which has a relatively complicated structure and cumbersome operation during the rewinding process.
