Description

TECHNICAL FIELD

[0002] The hot-pressing and drying treatment device for composite boards is a device for achieving the required physical properties and quality standards of composite boards through heating and pressing. The core is to evaporate the water in the board and cure the adhesive through heating, and to ensure the compactness of the board structure and the firmness of the interlayer bonding through pressing. Auxiliary systems such as ventilation, vacuum, and transmission are used to improve efficiency and quality.

[0003] The hot-pressing and drying treatment device mainly consists of a heating system, a pressure system, and a control system. The heating system usually uses electric heating or oil heating to heat the press plate from room temperature to a specified temperature within a certain time and maintain temperature accuracy. The pressure system consists of a hydraulic station and an oil cylinder, which moves the piston through hydraulic oil to apply pressure to the hot press plate and achieve pressing of the composite board. The control system adjusts and controls parameters such as temperature, time, and pressure through the control panel to ensure safety and stability of the work.

[0004] In the prior art, during the heating and drying process of the composite board by the electric heating plate, the heat of the electric heating plate is conducted inward through the surface of the board. The base material and adhesive of the composite board have a clear heat resistance threshold. When the central moisture is basically discharged, the thermal conductivity will decrease, and the heat will easily accumulate in the central area, causing the temperature to continue to rise. If the temperature exceeds the heat resistance threshold, the cellulose and hemicellulose of the wooden base material will pyrolyze, the central area of the composite board will become brittle and discolored, and the adhesive will decompose due to high temperature, causing the molecular chain to break and reducing the interlayer bonding strength.

[0063] The working principle of the present application is as follows: when the staff uses the device to perform hot pressing operation on the composite board, the staff places the composite board on the upper end of the pressing plate 7, and then starts the hydraulic pump 3 and the hot air fan 9 through the control panel 2;

[0064] When the hydraulic pump 3 is started, the hydraulic pump 3 guides the hydraulic oil into the two groups of hydraulic cylinders 5 through the two groups of hydraulic pipes 4, and the two groups of hydraulic columns 6 are respectively moved out of the two groups of hydraulic cylinders 5, so as to push the pressing plate 7 to move upward, and in turn drive the composite board to move upward;

[0065] ​​When the hot air machine 9 starts, the air flow enters the hot air machine 9 through the air inlet 10, and the hot air machine 9 raises the temperature of the air flow. The air flow enters the air outlet pipe 11, and then enters the air supply pipe 15 through the air outlet pipe 11.

Therefore, the air flow does not cause a loss, and the hot air in the multiple groups of heating pipes 20 heats the multiple groups of heating pipes 20. The temperature of the heating plate 8 is raised, and the pressing plate 7 cooperates with the heating plate 8 to perform hot pressing and drying on the composite board. The electromagnetic valve 30 is opened and closed at regular intervals, so that the hot air in the multiple groups of heating pipes 20 is replaced, and the heat of the multiple groups of heating pipes 20 is maintained.

[0066] When the hot air machine 9 starts, the air flow enters the hot air machine 9 through the air inlet 10, and the hot air machine 9 raises the temperature of the air flow. The air flow enters the air outlet pipe 11, and then enters the air supply pipe 15 through the air outlet pipe 11. The air supply pipe 15 is connected to the multiple groups of heating pipes 20 through the air supply pipe 15 and the multiple groups of air supply outlets. The air flow enters the multiple groups of heating pipes 20 through the multiple groups of air supply outlets and the air outlet pipe 26. The air outlet pipe 26 is connected to the first branch pipe 29 through the electromagnetic valve, and the electromagnetic valve is in a closed state. Therefore, the air flow does not cause a loss, and the hot air in the multiple groups of heating pipes 20 heats the multiple groups of heating pipes 20. The temperature of the heating plate 8 is raised, and the pressing plate 7 cooperates with the heating plate 8 to perform hot pressing and drying on the composite board. The electromagnetic valve 30 is opened and closed at regular intervals, so that the hot air in the multiple groups of heating pipes 20 is replaced, and the heat of the multiple groups of heating pipes 20 is maintained.
