A continuous gluing device for bamboo and wood composite rods

Abstract

The invention discloses a continuous gluing device for a bamboo-wood composite rod. The continuous gluing device comprises a workbench, a transmission device, a cleaning device, a heating device, a glue-coating device and a hot-pressing device, wherein the cleaning device, the heating device, the glue-coating device and the hot-pressing device are sequentially arranged at the top end of the workbench; the transmission device comprises a bamboo conveyor belt, a wood conveyor belt and a bamboo-wood composite rod conveyor line which is arranged at one side between the bamboo conveyor belt and thewood conveyor belt; the cleaning device, the heating device and the glue-coating device are arranged between the workbench and the bamboo conveyor belt; and the bamboo-wood composite rod conveyor line is arranged at one side of the glue-coating device. The cleaning device is arranged for being beneficial for clearing impurities and dust on wood and bamboo, so that the problem that uneven hot-pressing of the bamboo-wood composite rod is caused in the presence of the impurities and dust is avoided; and moreover, the problem that the quality of the bamboo-wood composite rod is affected as viscidity of the glue is affected as a result of presence of the impurities and dust is avoided.

Description

technical field [0001] The invention relates to the field of bamboo-wood composite gluing equipment, in particular to a continuous gluing device for bamboo-wood composite rods. Background technique [0002] Bamboo-wood composite materials refer to composite boards or squares made of bamboo and wood combined and glued in the same or different structural units. Bamboo-wood composite materials combine the excellent properties of bamboo and wood. Bamboo wood has high strength, so it has been widely used in furniture, interior decoration and even construction, shipbuilding, transportation and other industries that demand high-performance materials. The chemical composition of bamboo and wood is similar, but the tissue structure is different, so the quality of the glue between the two has an important impact on the performance of bamboo wood composites. Commonly used bamboo-wood composite rod gluing methods in the known technology include cold-press gluing and hot-press gluing. ...

Problems solved by technology

Since this heating method has a heat transfer process (heat transfer from the surface of the material to the glued surface), it still takes a long time, especially for bamboo-wood composite materials with low thermal conductivity, large thickness or volume. Time

At the same time, when the existing hot-press gluing machine is in use, it is necessary to send the assembled bamboo-wood composite rods into the gluing equipment in batches at one time, and then start the pressurizing equipment to pressurize the materials, heat at the same time, and carry out gluing. Stop the equipment, and take out the glued bamboo-wood composite materials in batches. In short, the traditional pressurization, heating, and gluing processes not only have low productivity, but also consume a lot of energy and cost.
