Flux-cored wire unwinding, supporting and rotating device

Abstract

The invention relates to a flux-cored wire unwinding, supporting and rotating device, which comprises a base and a main transmission shaft. The middle part of the main transmission shaft is rotatably connected with the base. The main transmission shaft is vertically arranged. The lower part of the main transmission shaft is arranged in the inner chamber of the base. A brake disc is installed at the lower end of the main transmission shaft. At least one brake which is matched with the brake disc for conducting emergency braking is arranged on the base. At least one damper which is matched with the brake disc for controlling rotating speed is arranged on the base. The upper end of the main transmission shaft stretches out of the base and a tray is installed at the upper end of the main transmission shaft. A tensioning ring is installed on the tray and is provided with at least two groups of tensioning shoes. A driving device which is used for driving the tensioning shoes to be expanded or contracted is arranged on the main transmission shaft. The flux-cored wire unwinding, supporting and rotating device has the advantages that the design is novel, the device is easy to manufacture, the loading and the unloading are facilitated, the device is suitable for unwinding of I-shaped wheels with different inner diameters, the device is convenient to operate, the rotating speed is controllable and the precise unwinding is realized.

Description

technical field [0001] The invention relates to the technical field of flux-cored welding wire production equipment, in particular to a flux-cored welding wire unwinding belt support rotary device. Background technique [0002] Flux-cored welding wire is a new type of welding material that has developed rapidly in recent years and has been widely used in industrially developed countries. Most of the flux-cored wires are rolled into a U-shaped cross-section by a long strip of flat metal sheet, and the granular flux is filled in the U-shaped metal groove, and then the final sealing and rolling step is carried out to roll the flux tightly. The welding wire that is pressed into the tubular welding wire and rolled into a tubular shape becomes the final required wire diameter through a series of pulling actions. This pulling action can also make the filled flux evenly fixed in the welding wire skin. With the rapid development of the flux-cored wire industry, flux-cored wire manuf...

AI Technical Summary

Problems solved by technology

The structure of the existing unwinding device is complicated, and sometimes there is a problem of unstable operation during unwinding, especially the speed cannot be controlled. The initial speed of unwinding is relatively slow, and the speed in the later stage of unwinding is accelerated, resulting in uneven unwinding of welding materials and affecting subsequent production.
