Description

Hot-rolled aluminum strip deviation detection and alarm device

technical field

The utility model relates to a detection and alarm device, in particular to a hot-rolled aluminum strip deviation detection and alarm device.

Background technique

The hot-rolled aluminum strip is transported through the roller table during the rolling process. Some of the roller tables do not have centering devices. Due to the high rolling speed, the aluminum strip is easily deviated on the roller table, causing the aluminum strip to be on both sides of the roller table. The edge contact caused scratches on the lower surface of the aluminum strip. During this process, operators often fail to detect the deviation in time and perform deviation correction operations, resulting in quality accidents.

A hot-rolled aluminum strip deviation detection and alarm device includes detection devices respectively arranged on both sides of a roller table for detecting edge positions on both sides of the aluminum strip, and the detection devices are electrically connected to a PLC control system of a hot rolling mill.

Further, the detection device includes a slide rail arranged between two adjacent conveying rollers and parallel to the conveying rollers, and two sliding rails are provided on the slide rail for detecting the positions of the edges on both sides of the aluminum strip. A detection sensor, the two detection sensors are respectively located on both sides of the roller table.

Further, the detection sensor adopts a photoelectric sensor.

Further, the photoelectric sensor is located below the apex of the conveying roller.

Further, the emission window of the photoelectric sensor is vertically upward.

Further, a position locking mechanism for locking the position of the photoelectric sensor is provided between the photoelectric sensor and the slide rail.
