The invention discloses adhesive-free pressing and sealing equipment based on high frequency. The equipment comprises a main working portion, a cooling portion and a recovering portion. The main working portion is used for heating and compressing wood to be machined through a die. The cooling portion is used for cooling the wood to be machined. The recovering portion is used for recovering the die. The main working portion, the cooling portion and the recovering portion are sequentially connected to form a circular production line through a conveying portion. According to the equipment, the heating manner adopts the high frequency to direct heat the wood, the heating period is short, the temperature in the wood is uniform, and media contaminating the surface of the wood are avoided. Moreover, the whole equipment forms the circular production line, heating, pressurizing and follow-up cooling and transferring of the wood can be completed continuously and automatically, working is efficient, and operation is simple.
