Veneer longitudinal glue jointer

Abstract

The invention discloses a veneer longitudinal glue jointer. The veneer longitudinal glue jointer comprises a main frame, a tooth cutting device, a tooth cutting conveyor, a toothing conveyor, a totalremoval conveyor, a clamping plate moving device, a sealing robot, a toothing device, and a total removal device; the toothing end of a veneer displaced in a horizontal direction is limited by arranging four downward pressing cooling pipes and four supporting and cooling pipes; the toothing end of the veneer is displaced in the same horizontal plane; the leveling of connectors of the toothing parts of veneers with different thicknesses can be realized; the smooth toothing of the veneers of less than 1mm can be also be completed by combing the small transfer error of a lead screw of the clamping plate moving device and a conveying roller in a transfer process; as the downward pressing cooling pipes and the supporting and cooling pipes are set to be capable of rotating, the downward pressingcooling pipes and the supporting and cooling pipes can move evenly and rotate along the veneer, the resistance of the middle plate toothing process is reduced, and the veneers of different thicknesscan be squeezed and fed; the complete meshing of the toothing position is realized; the toothing accuracy is improved; the extrusion and feeding force applied to the veneers can be relatively small; and the energy consumption is saved.

Description

Technical field [0001] The invention belongs to the technical field of veneer splicing in wood industry production, and particularly relates to a tooth joint device for longitudinal glue splicing of thick veneers. Background technique [0002] Veneer is a thin wood material with uniform thickness produced by peeling, slicing or sawing methods, generally less than 6mm, and is mainly used for the production of plywood and other glued laminated materials. Generally, high-quality veneers are used as panels, and low-grade veneers are used as backplanes, core boards, and long middle boards. Veneer can be divided into thick veneer (thickness is generally 2.0~6mm), thin veneer / thin wood (thickness is generally 0.2~2.0mm), and thin wood (thickness is 0.2~0.5mm). At present, due to the limitation of wood raw materials, it has been difficult to produce longitudinally integrated long veneers that meet the specifications of plywood. It is necessary to splice the veneers longitudinally, that...

Problems solved by technology

However, according to feedback from customers in the market, when splicing veneers with a thickness of 1.6~2.0mm, gaps in the tooth joints are prone to occur because the two plates cannot be fully displaced and fed; the splicing device is 3.6~6.0mm For veneers with a thickness of mm, the interface of the tooth joint is likely to be uneven, and the tooth tips protrude from the plane of the plate. This is because there is an error in the travel of the transmission device. The success rate of 1.6mm veneer is low; part of the hot melt glue sticks to the clamping device and the board delivery device
