Description

Technical Field

[0001] This utility model relates to the field of surface corona technology, and in particular to a surface corona device for aluminized paper. Background Technology

[0002] The surface energy of aluminized composite paper primarily depends on the surface energy of its outer film. This value fluctuates due to variations in processing technology and storage conditions. Insufficient surface energy leads to inadequate ink adhesion, causing ink smudging and ultimately product failure. To ensure strong ink adhesion during printing, two pretreatment methods are commonly used: one is online corona treatment during the film-paper lamination process; the other is applying a clear varnish to the film surface before lamination, followed by slitting into individual sheets after lamination to form a roll. Both methods effectively increase the film's surface energy, thus ensuring the quality stability of subsequent printing processes.

[0003] The prior art disclosure number CN207958860U describes an energy-enhancing device for the surface of aluminized composite paper, which includes a feeding platform, an energy-enhancing platform, and a discharging platform arranged sequentially from front to back, with a corona treatment machine arranged above the energy-enhancing platform.

[0004] This device uses a corona treatment machine to electrically shock single sheets of aluminized composite paper, increasing the surface tension and surface energy of the material.

[0005] In actual production, because the device cannot perform surface cleaning before corona treatment of aluminized paper, dust, debris and other impurities remain on the paper surface during corona treatment. These contaminants will hinder the effect of corona treatment, resulting in insufficient surface energy enhancement, which in turn affects the adhesion of subsequent printing inks.

[0006] Therefore, improvements are proposed. Utility Model Content

The air extraction assembly also includes a first air pump 7, which is fixedly installed on the inner wall of one side of the machine body 1, and the input end of the first air pump 7 is fixedly connected to the connecting pipe 8.

[0029] A gas-source ion bar 19 is provided on one side above the conveyor belt 16, and the gas-source ion bar 19 is fixedly installed on one side of the outer surface of the machine body 1. A fan hood 18 is provided on one side above the gas-source ion bar 19, and the fan hood 18 is fixedly connected to the inner walls on both sides of the machine body 1. A dust collection assembly is installed between the fan hood 18 and the machine body 1.

A corona treatment machine 11 is provided on the top of the metal seat 14. The corona treatment machine 11 and the metal seat 14 cooperate to perform corona treatment on the aluminized paper. This has been described in the prior art publication CN207958860U on a surface energy enhancement device for aluminized composite paper, so it will not be repeated in this application. Both ends of the corona treatment machine 11 are fixedly connected to a second ceramic seat 12, and the second ceramic seat 12 is fixedly installed on one inner wall of the machine body 1.

The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

[0032] Feeding and conveying stage:

[0033] The aluminized paper is placed on the conveyor belt 16 (this can be achieved through existing automatic feeding equipment or manual operation), and the motor 6 drives the roller 21 to rotate the conveyor belt 16. After the first vacuum pump 7 is started, a negative pressure is formed in the air groove 22 through the connecting pipe 8, the first filter 9 and the fixed pipe 23. The through holes 20 on the surface of the conveyor belt 16 generate an adsorption force, which firmly adsorbs the aluminized paper onto the surface of the conveyor belt 16, ensuring that no displacement or wrinkles occur during the transmission process.

[0034] Pre-treatment cleaning stage:

[0035] When the aluminized paper moves with the conveyor belt 16 to the area of ​​the air-source ion bar 19, the air-source ion bar 19 generates ion wind to neutralize the static electricity on the surface of the aluminized paper, making it easier for the attached dust to detach. At the same time, the second air pump 2 generates directional airflow through the hood 18, which collects the loosened dust, particles and other impurities after they are filtered by the second filter 17. This dual cleaning mechanism effectively removes surface contaminants and creates clean conditions for subsequent corona treatment.

[0036] Corona treatment stage:

[0037] The cleaned aluminized paper continues to be conveyed to the corona treatment area, where the corona treatment machine 11 generates a high-frequency, high-voltage electric field through the metal base 14. The first ceramic base 13 and the second ceramic base 12 provide double insulation protection. After corona treatment, the aluminized paper is smoothly conveyed out of the machine body 1 via the belt conveyor 4.
