Description

Technical Field

[0001] This utility model relates to the field of printing and laminating technology, and in particular to a precision-positioning automatic printing and laminating machine. Background Technology

[0002] Automatic printing laminating machines are high-precision devices used for laminating the surface of printed materials. They are widely used in industries such as packaging, advertising, and publishing. Through automated operation, these machines ensure accurate positioning of printed materials during the lamination process, thereby improving product quality and production efficiency.

[0003] Existing automatic printing laminating machines have a relatively simple structure. During the transportation of printed materials of different sizes and thicknesses, deviations can easily occur, resulting in insufficient positioning accuracy, unstable lamination quality, and problems such as bubbles and wrinkles, which affect production efficiency. At the same time, after long-term operation, melted film residue will adhere to the surface of the hot press roller, affecting the heat transfer and temperature uniformity of the hot press roller, and thus affecting the heat sealing quality.

[0004] Therefore, to address the problems of insufficient positioning accuracy, unstable lamination quality, and film adhering to the surface of the hot press rollers that affect heat sealing quality in existing automatic printing laminating machines, a precision-positioning automatic printing laminating machine can be designed. A limiting wheel positions and calibrates the printed material, improving accuracy and stability. The extrusion roller applies pressure evenly, improving the flatness and adhesion of the lamination. The use of a scraper and soft brush adds a cleaning device, resulting in a high degree of automation, improved cleaning efficiency, and guaranteed heat sealing quality. Utility Model Content

After lamination, the hot press roller rotates, and the cleaning rod rotates, causing the scraper to contact the hot press roller and remove any film residue adhering to the surface. The cleaning rod rotates again, and the soft brush contacts the hot press roller to remove any remaining film residue. This highly automated process improves cleaning efficiency and ensures heat sealing quality. Attached Figure Description
