Description
Technical Field
The utility model relates to a gilt technical field, concretely relates to by a wide margin gilding press syntropy paper taking off vacuum adsorption stripping off device that flattens.
Background
The aluminum foil hot stamping process can enable product packaging to have metal feeling, individuation, safety and environmental protection, belongs to relatively excellent after-printing decoration technology, and is more and more valued by people. The conventional gold stamping technology is divided into round-pressing round gold stamping and flat-pressing flat gold stamping, the working principle, mode, special equipment and the like of the round-pressing round gold stamping and the flat-pressing flat gold stamping are greatly different, wherein the most essential difference lies in that: in the rotary-pressing rotary-stamping process, a stamping plate, a stamping foil and a printing stock are contacted through two cylindrical parts, which belong to line contact, and have small contact area and larger pressure intensity; in the flat pressing process, a gold stamping plate, a hot stamping foil and a printing stock are contacted through an upper flat-plate-shaped workpiece and a lower flat-plate-shaped workpiece, the surface contact is realized, the contact area is large, the equipment pressure is large, but the pressure intensity of the contact surface is smaller than that of the round pressing round gold stamping; the difference results in different production efficiency and product types and different separation modes of the electrochemical aluminum foil and the printing stock after hot stamping, namely different paper uncovering modes, and the hot stamping paper uncovering mode is very important, and particularly in the large-layout hot stamping process, the hot stamping precision and the hot stamping speed can be seriously influenced.
The paper uncovering method of the rotary-pressing rotary-gilding is simple, and the film is easy to separate from the paper due to the linear contact, so that the roll paper and the gilded electrochemical aluminum foil can be directly separated only by separating the roll paper from the coiling direction of the gilded electrochemical aluminum foil by a certain angle; the common flat-pressing flat-stamping processing technology is characterized in that a hot stamping template is arranged on the surface of an upper platform or a movable platform of a hot stamping machine under certain pressure and temperature, a tooth row body with a printing stock moves between the upper platform and the movable platform to intermittently stop moving in the hot stamping process, the movable platform moves upwards to be instantaneously contacted with the upper platform, a printed matter, an electrochemical aluminum foil and the template are pressed in a short time, the picture and text of the hot stamping template are transferred to the surface of the printed matter through a dyeing material layer of the electrochemical aluminum foil, then the separation of the foil and paper is carried out, namely, the paper is uncovered, theoretically, a base film layer of the electrochemical aluminum foil is pulled away together with the part which is not transferred, and the hot stamped printing stock is taken away by the tooth row body; however, in actual production, the problem of difficulty in separating the hot stamping paper foils exists, mainly the adhesion force is large when the stripping layer and the base film layer of the electrochemical aluminum foil are separated from each other, the separation is difficult, especially flat pressing and hot stamping are performed, the hot stamping area is large, the adhesion force is large when the electrochemical aluminum foil is separated from a printed matter, the separation is difficult, relatively speaking, in the process of the same direction of the film and the paper, the moving direction of the electrochemical aluminum foil is always consistent with the moving direction of the printed matter, the separation difficulty is low when the aluminum foil and the printed matter move simultaneously after hot stamping is completed, and the defects of hot stamping such as unclear hot stamping handwriting, hairiness of the hot stamping, pen missing and broken picture, poor glossiness of the hot stamping picture and text and the like still exist.
In the prior art, a compressed gas nozzle is arranged at an outlet, and gas is sprayed between paper and an alumite to be subjected to hot stamping and is separated from the paper and the alumite, but in practical application, because the paper or the film is charged with static electricity or the air flow irregularly moves between the paper and the film, factors such as local negative pressure or turbulence and the like occur, the paper and the alumite are not completely separated, the defects of mutual adhesion exist, and the rolling of the alumite and the normal operation of the after-feeding of the paper are influenced, so that the existing large-amplitude flat-stamping flat-uncovering mode needs to be further optimized.
