Problems solved by technology

Due to the inevitable error between the anodized aluminum coil and the mechanical components, the foil feeding speed between several anodized aluminum coils cannot be completely consistent, and the structure of sharing a foil release roller makes it impossible to adjust each anodized aluminum coil individually, resulting in Hot stamping accuracy is reduced

Abstract

The invention relates to a digital holographic high-precision foil-feeding device of a bronzing machine, which comprises a foil-releasing device, a foil-coiling device and a color mark sensor, wherein the color mark sensor is positioned between the foil-releasing device and the foil-coiling device; the foil-releasing device can make a linear slide by means of a linear module slide block driven bya linear module servo motor and can finish the foil-feeding operation by a first servo motor, a hot stamping foil press mouth, a foil-releasing support plate, a first positioning guide shaft and a tensioning shaft; and the foil-coiling device can finish the foil-coiling operation by the cooperation of a compression cylinder, a tensioning wheel, a foil-pressing rubber roller and a second servo motor. Based on the two-step adjustment, the foil-feeding device ensures more precise foil-feeding operation, and the first servo motor and the second servo motor operate under a constant tension, thereby preventing the aluminum foil from deforming.

Description

【Technical field】 [0001] The invention relates to an assembly of a bronzing machine, in particular to a digital holographic high-precision foil feeding device of a bronzing machine, which belongs to the technical field of printing machinery. 【Background technique】 [0002] At present, the structure of the existing holographic foil feeding device is usually as follows: the anodized aluminum coil is installed on the foil release bracket; the servo motor drives the foil release roller to roll; the foil pressing shaft presses the anodized aluminum on the foil release roller, and drives the anodized aluminum through friction Move to complete the action of putting foil. The foil receiving part is composed of servo motor, fur wheel and foil receiving guide roller. The servo motor drives the fur wheel and the foil collection guide roller to roll through the toothed belt to complete the foil collection work. Above the stepping roller, an optical fiber detection device is installed ...
