Our company applied for an invention patent named "engineering blueprint printing unit, equipment and method" with patent number zl2019100427705 on January 16, 2019. After two years and three months of substantive examination and reexamination, we recently obtained the formal authorization of the State Intellectual Property Office and won the "invention patent certificate" issued by the state Intellectual Property Office.

The invention patent of "engineering blueprint printing unit, equipment and method" specifically relates to an environmental protection printing equipment and method. The hot melt engineering blueprint printer provided by the invention introduces the hot melt printing technology into the field of engineering drawings for the first time in history, and can be widely used in advertising, graphics, CAD and other industries. This device does not need to be equipped with traditional printing consumables such as nozzle, ink cartridge, toner drum and toner in the printing process, and will not produce any fine particles and volatilize any organic waste gas, so it will not cause any harm to human body and the environment. Hot melt engineering blueprint printer. It has completely solved the problems of ink disconnection and inaccurate fixing of traditional engineering printers. At the same time, it has unique product advantages such as simple operation, convenient maintenance, green environmental protection and efficient printing. It has epoch-making milestone significance for accelerating the development of green environmental protection in China's printing industry and promoting the continuous progress of China's information technology, and leads the development trend of future engineering blueprint printers.

As a  high-tech enterprise committed to the R & D, production, sales and service of special printers and their consumables, yuqiaofu technology has always adhered to the development concept of "innovation is the soul of enterprises" since its establishment. In 2006, the first fully automatic banner printer in the world was independently developed, which completely solved the industry bottleneck of complex and inefficient traditional manual banner making process. Over the years, the company has successively developed and produced a series of products, such as thermal printing banner printer, label printer, logo printer, hot melt photo printer, hot melt engineering blueprint printer, which are the world's first. The sources are independent research and development by enterprises, and the technical level ranks in the forefront of the world, filling the gap in the industry and the world. Among them, "hot melt color photo printer", "hot melt engineering blueprint printer" and "hot melt blueprint banner multifunctional integrated printer" won the honorary titles of "the first (set) technical equipment in Shandong Province in 2018, 2019 and 2020".

In recent years, our company has attached great importance to scientific and technological research and development, actively carried out technical research and core software development, and achieved remarkable results in independent innovation. The ability to create and use intellectual property rights of enterprises has been continuously enhanced, which has become an endogenous driving force to accelerate the upgrading of the company's series of products. Up to now, the company has more than 200 domestic authorized patents.

In the future, the company will continue to uphold the spirit of craftsmanship, continue to strengthen the R & D and transformation of patented technology, and provide strong technical support for the sustainable, stable and healthy development of the company.
