Operation process of veneer hot press!

Operation flow of veneer hot press

1、 Operation of hot press

Before startup:

Requirements before startup

1. The pressure of heat transfer oil can meet the process requirements and maintain the supply;

2. Cleaning of the upper and lower surfaces of the base plate and the upper surface of the hot pressing plate;

3. The pressure of accumulator is normal and the oil level of oil tank is normal;

4. All transmission parts are well lubricated, operate normally and electrical equipment is normal;

5. There is no air in the oil cylinder and the sealing ring is well sealed.

Preparation before startup

1. Close the main power switch and start the low-pressure pump to make the accumulator reach the required working pressure;

2. Open the heat transfer oil valve, close the heat transfer oil bypass circulating valve, and heat the hot pressing plate to reach the process temperature;

3. Start each conveyor of the pad circulation system;

4. Adjust the time of each time controller and the pointer position of the upper and lower limits of the pressure gauge according to the process requirements (if the total pressure changes greatly, adjust the pressure regulating mechanism of unloading valve and safety valve, etc.);

Startup, operation and shutdown:

Boot program

1. Start the plate loading oil pump motor and the plate feeding conveyor, and the assembled slabs will enter the plate loading machine one after another;

2. When the loading machine is full and the wet slab is loaded into the hot press at one time, start all relevant motors of the hydraulic pump system, open all solenoid valve switches and time controller switches, close the press and start boosting;

3. When automatic operation is required, turn on each corresponding automatic control switch;

4. During manual operation, raise and lower the pressure and maintain the pressure according to the process requirements, and open the pressure reducing valve at the end of the hot pressing cycle;

5. Start the unloading machine and unloading conveyor;

6. When the unloader pulls out the backing plate and reconstituted board, load the slab again and start the second hot pressing cycle;
