Factory with a number of tertiary institutions, the Institute of Electronic Control developed a high degree of automation, performance PLC automatic control system for good. System board molding units achieve fully automatic operation: open-book paper machine expansion axis automatic tensioning device, through the PLC signaling system to the expansion axis powder brake signal, automatically by the expansion to increase or decrease the friction axis to address the paper by large to small inconsistencies between the tensioning force. PLC control feed screw metering, water, foam, make a more accurate ratio of raw materials, production of different specifications in the production of the change of circumstances to ensure that the gypsum powder, water, foam ratio unchanged, re-board deviation + / -0.5kg. Auto-off board, transit, and transferring, using a programmable control machine distribution. Trigger off the use of encoders, precision cut board length. Programmable control of transit, quantity, distribution machine, running a balanced, reliable performance. Drying Room unit: sample drying room with a coal-fired or gas-type heat-conducting oil furnace to provide heat, the oil economy of the circulatory system so that the formation of the three interior drying temperature, more in line with the drying process of gypsum in the temperature curve. The board unit automatically: automatically add the new stack, reducing labor, reducing man-made break side plate collision situation, provided the rate of generation of products.
