Description

TECHNICAL FIELD

[0001] The utility model relates to a cold rolling mill uncoiling centering lamp tube protection device. BACKGROUND

[0002] Cold rolling is an important link of aluminum foil production, its main task is to input the cold rolling mill after uncoiling the hot rolling material, and rolls into the thickness required by the customer or combines with annealing to control the product state. In the cold rolling process, it is the key to ensure that the aluminum foil uncoiled extends in the correct direction, so it is necessary to adjust the centering position of the aluminum foil at any time. For this purpose, a precise light centering lamp tube device is added above the entrance of the cold rolling mill, which mainly emits high-frequency light through the centering lamp tube, irradiates to the strip conveying direction, and sets up a light signal receiver on the other side, judges whether the strip is centered by receiving the position of the shielding or non-shielding, and provides data for adjusting the trend of the aluminum foil. However, whenever the strip of the roll is uncoiled to the end, the end of the strip will rebound or fall freely because it is still in the arc shape and directly separates from the uncoiling roller. The end is generally sharp, which has the risk of impacting the centering lamp tube or other working parts. Since the centering lamp tube is valuable, once damaged, the loss is large, and at the same time, it will also affect the normal operation of the cold rolling mill, which needs to be improved.

[0021] like Figures 1-3 As shown, the cold rolling mill uncoiling centering lamp protection device includes an exit roll 1 and a strip 2 wound on the exit roll. A transition roll 3 is arranged along the strip conveying direction. After passing through the transition roll, the strip is conveyed horizontally. Two centering lamps 4 are arranged at intervals between the transition roll and the exit roll to detect whether the strip is conveyed in the center. The centering lamps are all embedded in a mounting base 5. The mounting base is fixed on a positioning tube 6 with an arc-shaped cross section. A baffle 7 is fixed between the two centering lamps on the positioning tube to prevent the tail of the strip from rebounding to the surface of the centering lamp when it is conveyed. A light signal receiver 8 is arranged above the strip along the illumination direction of the centering lamp.

[0022] In this embodiment of the utility model, the mounting base is provided with two mounting grooves 9 at intervals along the length direction of the centering lamp tube for embedding the centering lamp tube.
