Packaging steel strip for device and loop control device

Packaging steel strip for device and loop control device ( 1) Packaging steel strip for device: packaging cause of steel strip running deviation in operation are as follows: (1) tension control is bad, (2) the packaging steel strip flatness bad ( Flat, warping) (3) the wear of each roll. (4) mechanical centering is bad and so on, to the operation efficiency, bad quality, so rely on the entry of the acid tank, the export side of the device and winding in EPC device, control the running deviation. Acid tank inlet and outlet side of the device has two kinds: a. Machine guide way; b。 Automatically on the way, a. Is to use mechanical limit guide the motion of the packaging steel strip; B is to use the photocell will change packaging steel strip running deviation signal input to the cylinder fixed running deviation. ( 2) Loop control device it was to make the packaging steel strip groove sag ( Looping amount) Maintain a constant device. It depends on the inlet side of the tip of the central bottom is equipped with magnetic detector to detect the tip of the inner packing, the height of the steel strip to the entry side tensioning roller of the export of all kinds of speed control, get the identified loop length. Magnetic detector from acid tank bottom side to loading and unloading, in order to guarantee the accuracy, near the structure of the main components of the magnetic detector is magnetic.
