Abstract

The invention discloses an uncoiler uncoiling operation method. The method comprises the following steps of A, starting a lifting power cylinder when a previous coil of steel coil strip tail is advanced to a sliding sleeve plate, enabling a fixed sleeve plate stopping after rotating a first quadrant oblique angle, and starting a telescopic power cylinder to enable the sliding sleeve plate to extend out of the fixed sleeve plate; B, enabling a conveyor belt to stop advancing so as to enable the steel coil strip tail can stay on the fixed sleeve plate when the previous coil of steel coil strip tail are all fed into the fixed sleeve plate; C, overlapping a next coil of steel coil strip head to the previous coil of steel coil strip tail, starting the conveying belt to enable the next coil of steel coil to enter the conveying belt under traction of the previous coil of steel coil; and D, starting the lifting power cylinder when the next coil of steel coil strip tail enters the conveying belt, enabling the fixed sleeve plate stopping after rotating a fourth quadrant oblique angle clockwise, and meanwhile, starting the telescopic power cylinder to enable the sliding sleeve plate to retract into the fixed sleeve plate. Compared with the prior art, the method can be used for solving the problem that a strip head of an existing steel coil cannot smoothly enter a steel plate conveying channel of an uncoiler to be overlapped with a strip tail of a steel coil of a previous coil.

Description

technical field [0001] The invention relates to the technical field of overlapping the tape head and tail of steel coils, in particular to a method for overlapping the tape heads and tails of two steel coils by using an uncoiler. Background technique [0002] The uncoiler is one of the important equipment in the heavy coil tension leveler unit. The uncoiler has a frame body with a steel plate conveying channel. The frame body is respectively equipped with a pair of conveying rollers arranged up and down on the steel plate conveying channel; The strip head of the steel coil straightened by the straightening machine is sent to the welding machine through the steel plate conveying channel of the uncoiler to overlap with the strip tail of the previous coil, so that the welder can weld the steel coil of the next coil The belt head is welded to the tail of the steel coil of the previous coil; the currently used five-roll leveling machine includes three lower rollers arranged at in...
