Application of PLC in electrical control of plywood hot press

At present, plywood production enterprises mostly use multi-layer frame type hot press (veneer press and pre press have the same working principle as multi-layer press). Aiming at the problem that the control circuit of the press is more complex, the contact points are too many and the failure rate is high due to the relay contact control of the existing hot presses, it is proposed to use PLC control in the hot press control system, which can eliminate some relays and locking contacts, Simplify control circuit and improve equipment reliability.

The company mainly produces particleboard, density board, multilayer board, wood board and other complete sets of equipment. All kinds of equipment, such as digital control machine, automatic plate feeder, automatic roller dryer, etc. The products are sold all over the country and exported to Southeast Asia, South Asia, America, Europe, the Middle East and other countries and regions, deeply praised by domestic and foreign customers.
