 wooden pencil making machine process
The process of wooden pencil making:
The pencil plate is cut off,  and cut into wood, and then cut through the board and cut into a pencil board. Then through heating dry (60 ~ 120 ℃) and high temperature (130 ~ 200 ℃) degeneration, pencil board is made to reach the degree of softening, easy cutting.
Lead processing Graphite lead core match well with graphite and clay in a certain proportion, the kneading machine, three roller machine mixing, extruded through the pressure core machine a certain size (such as HB ~ 3 h lead core diameter is 1.80 ~ 2.10 mm) of the lead, the dry heating (50 ~ 150 ℃) and high temperature (800 ~ 1100 ℃) roasting, make its have certain mechanical strength and hardness, and finally made by immersion treatment.
Color lead core processing and graphite lead core is similar, but do not need to sintering. Processing method has two kinds: one kind is the clay, talc powder, adhesive, pigment, such as oil and wax evenly mixed, and made by molding, drying, known as the hybrid method;  another is kind of kaolin, talcum powder, such as colour and adhesive mixing extrusion into the lead or put the dry lead oil core container, under a certain temperature to make it fully absorb grease and made of called immersion method.
Pencil pole with planing machine machining screw plate cutting into a thickness of 4.1 ~ 4.1 mm, and have adapted to lead core diameter core trough trough plate, and then use the cement will lead and pencil board agglutination, under the clamping state of heating dry (50 ~ 120 ℃) 1 ~ 8 hours, the plane rod machining made from 178 ~ 180 mm in length of picea meyeri pencil.
The exterior decoration process will paint and print the white rod pencil, as well as the cutting light, printing mark and rubber top processing, making it a finished pencil with a certain specification, appearance color and decorative pattern.
