Ganxian peasant father and son invented green pencil instead of wooden pencil

Shijiazhuang, August 24th (Reporter: Luo Xuefeng) Wang Dianbiao and Wang Guoyi, father and son of Dongcun Village, Cuierzhuang Town, Ji County, Hebei Province, used 35 years to create their own machine tools, invented the rotating core pencil, replaced the traditional wooden pencil, and obtained the national utility model. The patents also obtained US invention patents and German utility model patents.

The pencil body is made of plastic, and it also comes with a lead cutting knife and lead shavings collection function. At the top, according to international standards, a safety vent designed to prevent children from swallowing accidentally and having salvage functions is designed.

“Grandpa is a carpenter, so his father, Wang Dianxi, particularly cherishes the resources of wood. In the early 1980s, when his father saw us go to school, it was more difficult for the child to use a knife to cut the pencil, and it was not safe, and it sprouted the idea of ​​creating a new pencil instead of a wood pencil. "Wang Guoyu said.

After more than a year of research and design, Wang Dianyu came out with the first generation of environmental pencils in 1983. After entering the market, Wang Diantang discovered that his invention was flawed: the rubber holding the pencil lead for a long time was prone to sticking. Subsequently, after more than three years of research and improvement experiments, he invented the second generation of environmental protection pencils, which became very popular on the market. The products also obtained national patents.

While the second generation of environmental protection pencils is hot on the market, Wang Dianbiao and Wang Guoyi and his son began the development of the third generation of environmental pencils. “From this time on, from mold design to mold making and testing, we got up at 5 or 6 o'clock in the morning and tried it repeatedly.” Wang Guoshao said that after repeated tests, the third generation of environmentally-friendly pencils had been successfully developed. , And in 2000 won the US invention patent and the German utility model patent. Afterwards, an upgraded version of the third-generation eco-friendly pencils was also successfully developed with a spin-off environmental pencil, and in 2016 it was awarded a national utility model patent.

At present, Wang Guoyi has also developed a set of environmentally-friendly pencil assembly machines to better promote the use of this technology. “I hope that the next step will be to better promote this technology, save wood, and also contribute to environmental protection.”
