Efficient flat hot stamping device

Abstract

An efficient flat hot stamping device comprises an n-shaped frame cover, wherein multiple mounting holes are formed in an upper panel of the frame cover, and guide pillars are fixedly connected to the frame cover and symmetric relative to the center line of the n-shaped frame cover; a final pressure adjusting plate, a hot stamping plate and a pressing plate are arranged below the frame cover sequentially, a cam mechanism is arranged below the pressing plate, and a pressure buffer device is arranged between the final pressure adjusting plate and the hot stamping plate; a sealing gas box is connected outside the pressure buffer device. The structure design of the final pressure adjusting plate, the pressure buffer device, the hot stamping plate and the pressing plate is adopted, so that when the hot stamping plate is contacted with the pressing plate, the contact time of the hot stamping plate and the pressing plate is prolonged due to the buffer function of the pressure buffering device, pressure between the hot stamping plate and the pressing plate is basically kept unchanged, the working efficiency for flat hot stamping can be improved, and the hot stamping effect is remarkably improved.

Description

technical field [0001] The invention relates to the field of printing machinery, in particular to a high-efficiency flat stamping device. Background technique [0002] In the existing technology, the working principle of the bronzing process is: under the action of combined pressure, the anodized aluminum is in contact with the hot stamping plate and the substrate. Due to the heating of the electric heating plate, the hot stamping plate has a certain amount of heat, and the anodized aluminum is heated to make the hot melt The dyed resin layer and adhesive melt, the dyed resin layer viscosity decreases, and the viscosity of the special heat-sensitive adhesive increases after melting, the aluminum layer and the anodized aluminum base film are peeled off and transferred to the substrate at the same time, as the pressure is removed, The adhesive cools and solidifies quickly, and the aluminum layer is firmly attached to the substrate to complete a hot stamping process. There are ...

[0002] In the existing technology, the working principle of the bronzing process is: under the action of combined pressure, the anodized aluminum is in contact with the hot stamping plate and the substrate. Due to the heating of the electric heating plate, the hot stamping plate has a certain amount of heat, and the anodized aluminum is heated to make the hot melt The dyed resin layer and adhesive melt, the dyed resin layer viscosity decreases, and the viscosity of the special heat-sensitive adhesive increases after melting, the aluminum layer and the anodized aluminum base film are peeled off and transferred to the substrate at the same time, as the pressure is removed, The adhesive cools and solidifies quickly, and the aluminum layer is firmly attached to the substrate to complete a hot stamping process. There are often two factors that affect the quality of hot stamping, one is the time of hot stamping, and the other is the control of pressure. The pressure is too large or too small. Both will affect the quality of hot stamping, and just like this, the efficiency of flat hot stamping can not be improved all the time
