In the light of cost index and pollution degree, the characteristics of kinds of pulp are analyzed in detail, and the GP pulp which is low cost, high-yield, no-pollution is chosen as the material of tableware. Based on material element analyzed, shaping technology is designed, the to and for single plane shaping equipment which is high shaping quality, high production efficiency and is easy to automatize is chosen. All kinds of measure are taken to solve the problems which are inequality in the shaping process of GP pulp, and dosage which matches with GP pulp is chosen. Some ways of fixing shape and heat up are analyzed, the technology of saving energy of heat pressing to fix shape being composed of oil heat and only one fixed shape in the mold is applied, with which it is high production efficiency, low cost to fix shape effectively, which saves energy 30 percent. In order to make the production line meet with material of GP pulp, measure are taken to solve the problem of pulp adhered to netlike molding which can lead to carry material difficult, the structure of fully automatic equipment is renovated, the loaded beam is optimizationally designed to make equipment structure compactand improve location precision and products quality. According to technologic flow and actual characteristic, Omron PLC is chosen as the core of the control system, proximity switch as detect unit take the place of touch switch, software is designed reasonably according to time order figure, hardware is simplified, the reliability of system is advanced, the stability of system is assured to make production order. Intelligence neuron PID system is studied theoretically which is made up of both neuron with self-organizing and self-learning function and ordinary PID with the characteristic of the simple structure and high stability, which can automatically tune the parameter with the change of system parameter, remain perfect performance.
