The invention discloses a hot stamping plate position adjusting device. The hot stamping plate position adjusting device comprises a roll body; a fixed frame is detachably arranged on the surface of the roll body; arc second through holes are formed in a group of opposite sides of the fixed frame in the direction of being perpendicular to the length direction of the roll body; second fixed bases are arranged in the second through holes in the direction of being perpendicular to the length direction of the roll body; second bearings are arranged in the second fixed bases; threaded rods are sleeved in inner rings of the two second bearings; gilding plates are connected to the threaded rods through threads; the other group of opposite sides of the fixed frame are parallel to the length direction of the roll body, and first through holes are formed in the opposite sides; first fixed bases are fixedly arranged on two ends in the first through holes; first bearings are arranged in the firstfixed bases; spline shafts are further arranged in the first through holes; and arc racks which extend into the first through holes are fixedly arranged on the sides, which face to the first through holes, of the gilding plates. According to the adjusting device, micro adjusting on positions of the gilding plates is realized by rotating the spline shafts and the threaded rods; the operation methodis simple; adjusting precision is high; and operators and gilding plates are not prone to being damaged.
