Description

Technical Field

[0001] The utility model relates to the technical field of plywood processing, in particular to a high-efficiency gluing device for plywood. Background Art

[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.

[0003] In the prior art, Chinese patent publication number CN210815979U discloses a gluing device for plywood processing, which belongs to the technical field of plywood gluing equipment. It solves the problem of difficulty in supplying glue and inconvenience in evenly coating plywood. Its technical points are: it includes a conveying platform, a gantry, a gluing roller body and a coating wheel. Several rollers are installed on the conveying platform, and a mounting frame is fixed on the top of the conveying platform. A driving roller is installed on the mounting frame. The 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 is tightly pressed against the plywood under the pressure of 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 operations, which is convenient and fast, and the glue is evenly and stably coated.

[0004] However, when this utility model is actually used, there is a lot of sawdust on the surface of the board, which is inconvenient to clean when applying glue. The sawdust will stick to the glue roller and mix into the glue. When too much sawdust is mixed in, it affects the quality of the glue, which may cause the glue bonding effect to be poor. Therefore, improvement is needed. Utility Model Content

[0016] The present invention is further configured as follows: an arc-shaped scraping groove is fixedly connected to the inner wall of the glue coating machine body, and a glue pump is fixedly connected to the outer surface of the glue coating machine body.

[0017] By adopting the above technical solution, the arc-shaped scraping groove is used to collect excess glue on the glue coating roller, and the excess glue is sucked out by the glue pump.

[0018] The present invention is further configured as follows: one end of the glue pump is fixedly connected to a glue extraction hose, and the glue extraction hose extends to the interior of the arc-shaped scraping groove.

[0019] By adopting the above technical solution, the glue suction hose sucks the glue collected in the arc scraping groove, thereby preventing excessive glue from overflowing from the arc scraping groove.

[0020] The utility model is further configured as follows: a glue delivery pipe is fixedly connected to the top of the glue pump, and a glue storage barrel is provided on the top of the glue coating machine body.
