the method comprises the following steps: feeding, wherein the feeding mechanism (1) quantitatively feeds materials into the mechanical paving machine (2) for paving;
step two: paving, wherein the mechanical paving machine (2) mixes the fibers and the adhesive, paves the mixture into a plate and sends the plate to a prepress machine (3) for prepressing;
step three: pre-pressing, wherein the pre-pressing machine (3) presses the plate for the first time;
step four: cutting, wherein the prepressing machine (3) discharges materials, and the longitudinal and transverse edge cutting machines (4) cut edges of the plates and cut the plates into smaller plates;
step five: hot pressing, wherein the synchronous conveyer (5) sends the plates into a plate loading machine (6), the plate loading machine (6) stacks the plates and sends the plates into a hot press (7), and the plates are hot-pressed and molded by the hot press (7);
step six: and the plate unloading machine (8) receives and stores the plates.
9. The working method of the automatic production line of the medium-density fiberboard of claim 1, which comprises recycling waste materials, and is characterized in that: the method specifically comprises the following steps:
the method comprises the following steps: the method comprises the steps of (1) recovering crushed aggregates, wherein the synchronous conveyor (5) is divided into a plurality of sections, the crushed aggregates fall onto a crushed aggregate recovery belt (91) along with the synchronous conveyor (5), and the crushed aggregate recovery belt (91) sends the crushed aggregates into a waste material recovery machine (92);
step two: waste plates are recycled, when the qualified plates pass through the recycling device (9), the telescopic rod (93) does not work, and the plates pass through; when the unqualified plate passes through the recovery device (9), the telescopic rod (93) is lifted, and the unqualified plate falls into the waste recovery machine (92).
