Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of film supply equipment, and specifically relates to a quantitative film supply device for electrochemical aluminum. BACKGROUND

[0002] Electrochemical aluminum is a special hot stamping material, usually composed of a base film layer, a release layer, a color layer, an aluminum plating layer, and an adhesive layer. Its production process involves coating the release layer and color layer on a thin film base, vacuum plating aluminum, then coating the adhesive layer, and finally rolling it into a finished product. Electrochemical aluminum is widely used in packaging, printing, decoration, and other fields, such as cigarette packaging, wine boxes, printed books, etc., and has functions such as improving product quality and anti-counterfeiting.

[0003] During the processing of electrochemical aluminum, the quantity of hot stamping needs to be controlled quantitatively according to the different order requirements. This is because the hot stamping effect and quality of electrochemical aluminum are highly dependent on the accuracy of the film supply. If the film supply quantity is not accurate, it may lead to problems such as blurred hot stamping patterns, uneven colors, or material waste. Therefore, a quantitative film supply device is needed to accurately control the quantity of hot stamping.

[0004] However, most existing quantitative film supply devices are controlled by electronic equipment. Although this method can achieve a certain degree of accuracy, it also has many shortcomings. First, the use of electronic equipment increases equipment costs and energy consumption. Second, electronic equipment needs to be regularly checked and calibrated by professionals, which is relatively inconvenient. This not only increases labor costs, but also may cause production interruptions due to equipment failure or untimely calibration. In addition, the stability of electronic equipment in complex industrial environments also poses certain challenges.

[0005] In summary, the quantitative film supply step in electrochemical aluminum processing has an important impact on production efficiency and product quality. Although existing technology can meet basic needs, there is still room for improvement in terms of cost, stability, and maintenance convenience. UTILITY MODEL CONTENT
