Uncoiler

Abstract

The invention discloses an uncoiler which comprises a base. A spindle box is slidably installed on the base. A spindle driven by a first drive device is rotatably installed in the spindle box. An expanding and shrinking device is arranged at one end of the spindle. A second drive device connected with the expanding and shrinking device is arranged in the position, at the other end of the spindle, of the spindle box. The second drive device penetrates through the inside of the spindle and transversely drives the expanding and shrinking device. By adoption of the uncoiler, steel coil finishing lines and steel plate finishing lines can be mixed together, the situation that both steel coils and steel plates can be subjected to finishing on a production line can be achieved, and interference does not occur when the steel coils and the steel plates are switched; compared with conventional two production lines, investment cost is greatly saved, and the occupation area and the space occupancy rate are greatly lowered; meanwhile, the production usage rate is effectively increased; and further, the uncoiler is simple in structure, low in manufacturing cost, high in structural strength and long in service life.

Description

technical field [0001] The invention relates to an uncoiler. Background technique [0002] At present, in the plate finishing production line, the uncoiler is one of the key equipments, and the design and manufacturing level of the uncoiler is the key to the realization of the finishing process. At present, the existing plate finishing line in the industry is a single steel coil finishing line or steel plate finishing line. The steel coil finishing line generally finishes the thin plate, and the steel plate finishing line generally finishes the thick plate; when needed When finishing steel coils and steel plates, it is necessary to invest in a production line each. The two production lines not only require a huge investment in equipment, but also take up a lot of space. Production line downtime, resulting in low utilization. [0003] At the same time, when finishing the steel coil, two uncoilers are required to work together (the two uncoilers are respectively located on b...

At present, the existing plate finishing line in the industry is a single coil finishing line or steel plate finishing line. The steel coil finishing line generally finishes the thin plate, and the steel plate finishing line generally finishes the thick plate; when needed When finishing steel coils and steel plates, it is necessary to invest in a production line each. The two production lines not only require a huge investment in equipment, but also take up a lot of space. Downtime of the production line, resulting in low utilization

[0003] At the same time, when the steel coil is finished, two uncoilers are required to work together (the two uncoilers are respectively located on both sides of the steel coil). The structure of the reel is poor in rigidity and structural strength, which seriously affects the service life; moreover, the existing uncoiler has a complicated structure and high manufacturing cost
