Rotary bronzing machine

Abstract

The invention discloses a rotary bronzing machine. The rotary bronzing machine comprises a rack and further comprises an unwinding device, a deviation rectifying device, a bronzing material storage device, a bronzing device, a waste film collecting device, a drying device and a winding device which are arranged on the rack. The bronzing device comprises a printing roller, an impressing roller anda cooler. A bronzing material is arranged between the printing roller and the impressing roller. A printing substrate is arranged between the bronzing material and the printing roller. The cooler comprises a gas conveying nozzle with the opposite moving direction of the printing substrate. The gas conveying nozzle is arranged between the bronzing material and the printing substrate. A sensor usedfor detecting passing of the printing substrate is arranged between the bronzing device and the deviation rectifying device. An unwinding tension device is connected to the rear end of the unwinding device. A winding tension device is connected to the front end of the winding device. The deviation rectifying device comprises a deviation-rectifying correcting frame and a servo motor for driving thedeviation-rectifying correcting frame to make movement. Distance sensors are arranged on the two sides of the deviation rectifying device. According to the rotary bronzing machine, the probability ofthe trailing and water ripple phenomena can be decreased by a large margin, the printing quality is good, and the printing efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a round stamping machine. Background technique [0002] Hot stamping refers to the process of hot stamping anodized aluminum foil onto the surface of the substrate under a certain temperature and pressure. The graphics and texts of anodized aluminum hot stamping show a strong metallic luster, the colors are bright and eye-catching, and will never fade. Gold and silver anodized aluminum, in particular, embellishes the surface of printed matter with its magnificent, exquisite and elegant decoration, enhances the artistry of printed matter, and plays a prominent role in promoting the theme; its brightness greatly exceeds that of printed gold and silver, making the product It has a high-end feeling and gives people beautiful enjoyment. At the same time, due to the excellent physical and chemical properties of anodized aluminum, it plays a role in protecting printed mat...

Problems solved by technology

However, when the base film layer accumulates a certain amount of heat or the base film layer has poor temperature resistance, and the force between the peeling adhesive layer and the base film layer on the aluminum powder of the color layer is greater than the bonding force between the adhesive layer and the paper, incomplete peeling will occur. Then there will be abnormal peeling noises. Under the mechanical line contact extrusion force, the aluminum powder of the color layer and the adhesive layer will be accumulated on the dragging layer of the hot stamping plate, resulting in hot stamping cracks or water ripples. At this time, the positioning is accurate The speed decreases, and the running resistance of the aluminum foil increases

[0004] At the same time, in the process of unwinding and conveying, there will be deviations, which will make the anodized aluminum foil and the printing plate graphics and texts inconsistent, and some graphics and texts will be exposed and cause incompleteness.

In addition, most of the start-up operations of the existing hot stamping machines are started manually. If the start is too early, some hot stamping paper will be rolled in vain, resulting in waste; if the start is too late, some materials cannot be hot stamped and must be re-clamped after an emergency stop. , time-consuming and labor-intensive

The same problem exists when the foil stamping machine is stopped, causing waste and inefficiency in production
