Artificial board pre-presser

The utility model discloses an artificial board pre-presser. The artificial board pre-presser comprises a frame and a steel belt. A transmission mechanism, a pre-press roller mechanism, a primary press roll connected with the pre-press roller mechanism and a pressure maintaining roller mechanism connected with the primary press roller mechanism are arranged on the frame. The pressure maintaining roller mechanism is provided with pressure maintaining rollers, and each pressure maintaining roller is internally provided with a heating cavity for storing heat energy. The heat in the heating cavity is transferred to a slab through the pressure maintaining rollers. A heat inlet and a heat outlet are arranged on the pressure maintaining roller. A plurality of pressure maintaining rollers are arranged in the pressure maintaining roller mechanism, the pressure maintaining time is long, the slab strength is good, and the product quality is good. In the pre-press process of the slab, the slab can be heated by the pressure maintaining rollers so that the water in the slab can be discharged, the hot pressing time is shortened, and the production efficiency is improved. The artificial board pre-presser belongs to the technology that when orientation plates and straw boards are pressed, a mould release brush roller can be utilized to brush mould release agent.
