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 conveying device, a tooth jointing conveying device, a veneer output conveying device, a clamp plate moving device, a gluing device and a tooth jointing device, wherein the tooth jointing device mainly comprises a support, a first air cylinder, a downward pressing connection piece, a downward pressing cooling pipe, a support cooling pipe and a support connection piece. By respectively arranging two lifting components at two ends of thesupport connection piece, lifting motion of the support cooling pipe is achieved, veneers after completing tooth jointing on the tooth jointing device is raised when the veneers are output, retentionof hot melt glue on the support cooling pipe, the clamping component and the veneer output conveying component is avoided, the hot melt glue on the veneers after being formed through the tooth jointing is cooled once again when the veneers are output, and good tooth jointing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of veneer splicing in wood production, and in particular relates to a tooth joint device for longitudinal glue splicing of thick veneers. Background technique [0002] Veneer is a thin wooden material with uniform thickness produced by rotary cutting, planing or sawing, generally less than 6mm, and is mainly used for the production of plywood and other glued laminated timber. Generally, high-quality veneers are used as panels, and low-grade veneers are used as backplanes, core boards, and long-term 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), thin wood (thickness is 0.2~0.5mm). At present, due to the limitation of wood raw materials, it is already difficult to produce vertically integrated long veneers that meet the specifications of plywood. It is necessary to splice the veneers longitudinally with glue, that is,...

Problems solved by technology

However, according to feedback from customers in the market, when the board is fed, the veneer displaced from the previous process may leave hot melt adhesive liquid; The glue is solidified, the hot melt glue on both sides of the cooling pipe is not solidified in time, or the hot melt glue sticks to other equipment before the veneer enters the gear joint equipment and is not cooled, resulting in the board being clamped by the cooling rod when entering and exiting the board Scratching of parts and transmission parts, etc., causes hot melt adhesive to stay on cooling rods, clamping parts, and transmission parts, which needs to be cleaned frequently, which affects production efficiency and affects the effect of tooth connection of subsequent veneers
