Description

An eco-friendly processing system of recycled printed matter laminating The present invention relates to an eco-friendly processing system for recyclable laminated printed materials. Generally, paper products used for printed materials or packaging are manufactured with a multi-layer structure and designed to simultaneously ensure durability, print quality, and appearance stability. The core of the manufacturing process for these paper products lies in the lamination of base papers to a uniform thickness. Specifically, the tensile strength, water resistance, and smoothness of the paper are enhanced through a lamination process in which a first base paper and a second base paper are laminated using adhesive under specific pressure. Subsequently, the finished product is produced through subsequent stages such as printing, drying, and cutting. This lamination process is widely utilized not only in the general printing industry but also in various fields such as food packaging, shipping boxes, industrial labels, cardboard cases, and advertising prints. While such lamination technology has long been established as a fundamental technology in the paper industry, the establishment of mass production systems has led to the problem of waste paper and scraps generated during post-lamination processing becoming increasingly serious environmental and economic issues. In particular, large amounts of scrap are generated as corners and excess material are cut off during the processes of cutting, folding, or shaping laminated sheets to standard sizes. Most of these scraps are either discharged outside the production process for disposal or recycled into low-cost recycled paper or fillers after undergoing separate crushing, compression, and washing processes. This method has limitations, including low resource efficiency and the generation of additional energy and wastewater. Furthermore, conventional printing processing systems suffer from low production efficiency because devices are separated by process. For example, since laminating, cutting, gluing, folding, and packaging devices operate independently, manual transfer or temporary pauses between processes are unavoidable. In such separated systems, repetitive tasks such as position correction between devices, sheet alignment, and residue removal occur, leading to longer overall production cycles and higher defect rates. Accordingly, various prior art technologies have proposed mechanical devices to implement automatic cutting or folding of laminated sheets. For example, known technologies include automatic packaging techniques that manufacture packaging boxes by cutting the sheet at a specific location and folding it at a certain angle, or waste paper processing devices that collect and recycle the cut residue. Another approach involves systems that recover waste paper generated during the printing process to a separate storage facility, then crush and mold it to recycle it into cushioning or thermal insulation materials. However, these conventional technologies were not implemented as a single integrated system that organically connects the entire process from lamination to folding, molding, and recycling; instead, each process was performed individually or recycling functions existed merely as additional components. In particular, they remained at the level of simply converting scraps back into raw materials, lacking the concept of directly recycling them as structural components of finished products. Consequently, most of the scraps generated during the cutting and folding processes were discarded, leading to reduced production efficiency and resource waste. Furthermore, in the recent paper industry, driven by the trends of ESG management and carbon reduction, waste-reducing production systems and the utilization of eco-friendly materials have become essential requirements. While technological attempts are being made in the production processes of printed materials and packaging—such as reducing adhesive usage, increasing waste paper recycling rates, and designing non-adhesive structures—practical technologies that simultaneously implement lamination and recycling processes remain lacking. Therefore, there is a need for a system that automates the cutting and folding processes based on laminated sheets, while directly recycling the scraps generated during the process into fixing members that maintain the product's structure. By performing lamination, processing, molding, and recycling within a single process, such a system can improve production efficiency and minimize waste generation, and furthermore, contribute to the overall eco-friendliness of printed material manufacturing and the enhancement of resource circularity. In other words, the industry urgently needs the development of an eco-friendly, recyclable processing system for printed material lamination that can simultaneously improve the efficiency of the lamination process and achieve structural recycling
