Description

Simulation detection device and method for detachment force of anodized aluminum film after hot stamping

technical field

The invention relates to a device for simulating and detecting the detachment force of anodized aluminum film after hot stamping.

The invention also relates to a method for simulating the detachment force of the anodized aluminum film after hot stamping.

Background technique

The anodized aluminum film is made by coating a release layer, a color layer on a film sheet, vacuum aluminizing and then coating an adhesive layer, and finally rewinding the finished product. Anodized aluminum film is the first choice material for hot stamping various colors and characters on the surface of paper, printing ink, plastic, wood, leather, cardboard, cloth, etc. The pattern is clear, beautiful, colorful, dazzling, wear-resistant and weather-resistant. Anodized aluminum hot stamping has incomparable advantages in improving packaging grades, brand recognition and product anti-counterfeiting. Therefore, it is more and more widely used in the surface decoration of folding cartons. In recent years, the materials and printing processes used in folding cartons have undergone major changes, such as aluminum foil paper, laser cardboard, vacuum aluminized transfer paper and other packaging materials have gradually been applied, UV printing, UV glazing, screen printing, etc. Matte (ice flowers, refraction) and other printing and surface finishing processes have also been born one after another, and these have put forward higher requirements for anodized aluminum hot stamping.

The main factors affecting the hot stamping process of anodized aluminum are hot stamping temperature and hot stamping pressure. All anodized aluminum films have their recommended hot stamping temperature, and the temperature range is usually about ±10°C. In the production process, increasing the temperature is often the first solution that operators think of when encountering problems such as not being able to iron or not being firmly attached. However, excessively increasing the hot stamping temperature is not conducive to solving the problem, but may cause the adhesive molecules of the adhesive layer to stick together, causing paste, and at the same time cause the dyed layer to overheat and cause rainbow patterns and spots to appear. Aluminum will also oxidize at high temperature and darken the color. The influence of pressure adjustment in hot stamping of anodized aluminum on the quality of hot stamping cannot be ignored. If the pressure is small, it will not be ironed or the hot stamping pattern will not be attached firmly; if the pressure is high, it will cause problems such as paste and thicker hot stamping lines. The adjustment of the anodized aluminum hot stamping process requires a quantitative judgment on the detachment force of the anodized aluminum film after hot stamping.

At present, there is no relevant device in China that can detect the detachment force of the anodized aluminum film after simulating hot stamping. The relevant methods for detecting the detachment force are all judged by the hand feeling of pulling away after sticking with single-sided adhesive. Whether the detachment force of the aluminum film is large or small, there is no relevant device that can provide a quantitative data to indicate the actual detachment force of the anodized aluminum film.

As shown in Figures 1 to 5, the present invention provides a simulation detection device for the separation force of anodized aluminum film after hot stamping, which includes a printing platform 1 and a substrate 2 placed on the printing platform 1, and a The ironing plate 3 corresponding to the substrate 2 is provided with a hot stamping plate, and at least two pressure rollers 4 are arranged between the ironing plate 3 and the substrate 2, and the anodized aluminum film 5 passes under the pressure roller 4 The two ends of the electrochemical aluminum film 5 are respectively provided with a flattening structure and a take-up structure, and two positioning rollers 6 are arranged between the pressure roller 4 and the take-up structure, and a tension detection balance roller is arranged below the two positioning rollers 6 7. The tension detection balance roller 7 is connected to the pressure detection sensor 8, and the pressure detection sensor 8 is connected to the data processing unit. The anodized aluminum film 5 is wound from the top of one positioning roller 6 to the bottom of the tension detection balance roller 7, and then wound to another positioning roller. Roller 6 above.

The flattening structure includes a flattening roller 9, and the side of the flattening roller 9 away from the pressure roller 4 is provided with a damping suspension, and the damping suspension includes a soft damping plane 10 and a hanging weight 11 hanging on the lower end of the soft damping plane 10, The soft damping plane 10 and the leveling roller 9 sandwich the anodized aluminum film 5 in the middle. Since the lower end of the soft damping plane 10 is suspended with a suspended weight 11, the soft damping plane 10 exerts a certain pressure on the anodized aluminum film 5, and the anodized aluminum film 5 moves between the soft damping plane 10 and the stretching roller 9 , a certain resistance needs to be overcome.
