Series type continuous automatic enf-grade plywood production line and production method

Abstract

A series type continuous automatic ENF-grade plywood production line and a production method is set forth. The production line is at least composed of three serially connected independent process units with the same processing flow, which are core initialization, thickening circulation and product setting. Each process unit at least includes the following procedures: surface sanding, gluing, automatic lay-up, constant-thickness hot pressing, board overturning and cooling, defect scanning and repairing. The thickening circulation process unit can form a ring-shaped production line through a loop formed by the above procedures, or can form a linear production line by repeatedly extending above procedures. The present disclosure has the beneficial effects that the procedures of aging and prepressing of veneers, which lead to the stagnation of production process, are omitted, and the main obstacles in the continuous and automatic production of plywood are overcome.
