MANUFACTURING EQUIPMENT, MANUFACTURING METHOD OF POLYURETHANE PLYWOOD AND POLYURETHANE PLYWOOD PRODUCED THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/099433
Kind Code:
A1
Abstract:
A manufacturing equipment and manufacturing method of the polyurethane plywood are provided according to the present disclosure. The manufacturing equipment of a polyurethane plywood comprises: a preprocessing device configured to provide veneers conforming to a preset specification; a lay-up and glue spreading device configured to divide the veneers into multiple types, wherein a plurality of types of the veneers are sequentially joined to form a continuous veneer strip, and the single-sided glue spreading process is performed on the continuous veneer strip; and the plurality of types of veneers being processed with single-sided glue spreading are stacked in sequence to form a pile of veneers; a conveying and preheating device configured to transport the pile of veneers from the lay-up and glue spreading device to the hot pressing device, and preheating the pile of veneers during the conveying process; a hot pressing device configured to perform a continuous flat pressing process on the pile of veneers with heat transfer medium to form a semi-finished board; and a raw board handling device configured to perform one or more of the following processes: to perform detection on semi-finished board, to deal with the disqualified semi-finished board, to cool the semi-finished board, and to clip the semi-finished board. This present disclosure makes it possible to apply polyurethane adhesive on a large scale in the polyurethane plywood industry and to improve product quality as well as the environmental performance.
