Plywood, also called multi-layer board, is one of common materials for furniture and is an artificial board. The plywood is made up by using wood sections through the processes of rotary cutting to obtain single board or planing to obtain thin single board, coating adhesive on the single board, using the coated single board and making it into plate blank which can be criss-cross formed according to the wood grain direction, and pressing under the condition of heating or not heating, and usually using odd number of layers of single board.

At present, when a plywood with a longer size is produced, when multiple layers of veneers are glued, multiple sections of veneers are required to be connected end to end, two adjacent veneers are required to be lapped at the joint of the veneers and the veneers, and in order to enable the thickness of the joint to be consistent with the thickness of other parts of the plywood, the joint needs to be polished, so that the joint is thinned. In the actual production process, the upper side face of one end and the lower side face of the other end of a single plate are respectively polished at two ends, and only polishing is needed within a certain length range of the end part.

The existing single plate grinding head machine is characterized in that after two ends of a single plate are polished, the single plate is conveyed out of the single plate grinding head machine through a conveying belt of the single plate grinding head machine. However, since the surface of the polished veneer is rough and the veneer is thin, in this conveying mode, one end of the veneer which is conveyed out of the veneer grinding machine first can drop and scrape the upper surface of the veneer which is stacked on the lifting table, and the two veneers scrape and even scrape and break the conveyed veneer.
