Abstract

The invention provides an uncoiling device including a coiling block, an uncoiling diameter detection probe, a current regulator connected with the uncoiling diameter detection probe and a detent connected with the current regulator. The detent is connected with the coiling block. Comparing to an existing technology, according to the uncoiling device, the coiling diameter size can be judged in real time through the uncoiling diameter detection probe; current of the detent can be changed according to the coiling diameter size; braking torque of the detent can be determined according to inherentcharacteristics of the detent and the current; and the purpose that the tension required during uncoiling is kept constant can be achieved.

Description

technical field [0001] The invention relates to the technical field of uncoiling, in particular to an uncoiling device. Background technique [0002] The uncoiler is a special equipment for metal plate leveling. It is used for leveling steel plates and uneven plates. It can be composed of uncoiling, leveling, shearing production lines and other plate product production lines according to relevant configurations. The uncoiler is suitable for machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries. [0003] The body of the uncoiler is a welded box-shaped structure, and the variable-frequency speed-regulating motor drives the reel shaft to provide the main power for the uncoiler after being decelerated by the gear box. The reel of the uncoiler is a hollow shaft, which is supported on the gear box by two bearings, and a transmission spur gear is installed between the bearings. The gearbox is lubricated by forced lubrication ...
