Plywood glue spraying equipment

Abstract

The invention discloses a plywood glue spraying equipment. The equipment comprises a glue storage system, a glue spraying system and a glue feeding system; the glue storage system comprises a first rack and a glue storage tank; the glue spraying system comprises a second rack and a glue spraying device arranged on the second rack; the glue feeding system comprises a glue conveying device used forconveying glue in the glue storage tank to the glue spraying device and a heat preservation device used for guaranteeing constant-temperature conveying of the glue; and the gas conveying device is used for supplying gas to each nozzle. According to the plywood glue spraying equipment, constant-temperature glue feeding can be achieved, glue is prevented from being solidified due to temperature reduction in the conveying process, and therefore the flowability and viscosity of the glue are guaranteed. Besides, the plywood glue spraying equipment adopts a nozzle spraying mode to conduct gluing onthe plate blank at the gluing station, the speed is high, glue can be evenly sprayed to all the positions of the plate blank at the same time, the solidification degree of the glue at all the positions of the plate blank is consistent, and the spraying effect is improved.

Description

technical field [0001] The invention relates to a plywood processing equipment, in particular to a plywood glue spraying equipment. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. As one of the commonly used materials for furniture, plywood is one of the three major boards of wood-based panels, and it can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically arranged on both sides of the center layer or core. The slab made of the ...

Problems solved by technology

[0004] However, the above-mentioned plywood spraying process device only heats the glue in the storage box to soften it, but during the glue transportation process, when the glue is transported in the glue delivery pipeline, the heat in the glue will be continuously lost, making the temperature of the glue constantly This change is more obvious when the length of the glue conveying pipeline increases, so that the glue will continue to solidify during the conveying process, thus affecting the fluidity and viscosity of the glue
