The DY002 high-speed Two-sided printers is a new generation of pencil trademarks printing device (patented) which is used generally, efficiently, reliably. The printer is mainly used to print trademarks on various pencils, such as round, hexagonal and triangular pencils or other shapes of pencil (for different shafts, only replacement of the corresponding baseboard is needed). All materials for main parts of body are made of quality carbon steel to ensure stable running. The printer has novel appearance, compact and flexible configuration, and it is easily operated, adjusted, fixed. Because of quality bearing as transmitting parts, no lubricant is needed during operation (except regular replacement), it is the first choice for pencil manufactures to print their brands. As a result of use of variable stepless speed, feeding speed can be chosen according to the actual need of customers.
