Description

Technical Field

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them together with adhesive. It is usually made with an odd number of veneers, and the fibers of adjacent layers of veneers are glued perpendicular to each other. In plywood production companies, the wood boards are generally coated with glue using a gluing machine.

[0003] In the prior art, Chinese Patent Publication No. CN210815979U discloses a gluing device for plywood processing, which belongs to the technical field of plywood gluing equipment, and solves the problem that glue is difficult to supply and not conducive to uniform coating when gluing plywood. Its technical points are: it includes a conveying platform, a gantry, a gluing roller body and a coating wheel, a plurality of rollers are installed on the conveying platform, a mounting frame is fixed on the top of the conveying platform, a driving roller is installed on the mounting frame, and a plywood to be coated with glue is provided between the driving roller and the supporting roller. The plywood moves under the drive of the driving roller, and the gluing roller body and the plywood are tightly pressed by the compression spring. Under the transportation of the glue pump, the glue is evenly coated along the surface of the gluing roller body, and the excess glue is collected in the glue storage pool. At the same time, the coating wheel can also cooperate to perform double-sided gluing operation, which is convenient and fast, and the glue is evenly and stably coated.

It is not convenient to heat the glue during the feeding process, and the glue is easy to solidify when the temperature is low, which can easily cause pipeline blockage, so it needs to be improved.
