Description

Two-color hot stamping machine unwinding mechanism

technical field

The invention relates to an uncoiling part in an electronic shaft hot stamping machine, specifically an uncoiling rack in a two-color hot stamping machine.

Background technique

As we all know, the bronzing process uses the principle of heat transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metal effect. Because the main material used for bronzing is anodized aluminum foil, bronzing is also called anodized aluminum hot stamping. . Anodized aluminum foil is usually composed of multi-layer materials, the base material is usually PE, followed by separation coating, color coating, metal coating (aluminized) and glue coating.

In the printing industry, hot stamping of anodized aluminum foil on paper is commonly used, which is called hot stamping, and hot stamping is a general term for a process. Bronzing does not mean that what is hot on is golden. There are many kinds of hot stamping paper materials, including gold, silver, laser gold, laser silver, black, red, green and so on.

1. Ordinary gold, laser gold hot stamping. It can be used for hot stamping on most products, including gold cards, silver cards, laser cards and glass cards, and its application is relatively common.

2. Positioning holographic foil stamping. Holographic laser positioning anodized aluminum is a special process application in design, with corresponding anti-counterfeiting patterns, which can greatly improve the anti-counterfeiting ability of the product, and at the same time improve the grade of the product. This kind of anodized aluminum is generally produced domestically. Compared with imported products, the price is cheaper, but the hot stamping performance is slightly worse. Holographic laser positioning anodized aluminum has a great relationship with the control of hot stamping temperature, hot stamping pressure and vehicle speed, and even hot stamping models.

3. The special application of anodized aluminum in technology. Ironing first and then printing is a new idea in the cigarette label design and printing industry. The application of this process has high requirements for anodized aluminum. In addition to achieving the requirements of accurate bronzing position, smooth and bright surface, balanced and uniform pressure, no blistering, and no paste, special attention must be paid to the edge of the bronzing pattern without obvious pressure. The hot stamping anodized aluminum should have good adhesion on the hot stamping surface, and there should be no obvious scratches and scratches.

However, the hot stamping process is actually a process in which paper is heated and pressed; in the production process, it is necessary to minimize various unfavorable factors of paper deformation, which is of great help to the smooth progress of the hot stamping process and the improvement of the product qualification rate; therefore In order to achieve this goal, the present invention provides an unwinding mechanism that can be applied to electronic shaft hot stamping machines through improvement, which is the unwinding part of the electronic shaft hot stamping machine. During operation, the unwinding frame realizes unwinding of the paper roll during the hot stamping process. Roll, through the uniform uncoiling in the working process can improve the bronzing efficiency of the electronic shaft bronzing machine.
