A continuous gluing device for bamboo and wood composite rods

Abstract

The invention discloses a bamboo-wood glued rod continuous gluing device and is characterized in that a speed regulating motor adopts a three-section input mode to provide torque for multiple pairs of rollers with V-shaped grooves through chain transmission and a transmission mechanism, the multiple pairs of rollers with V-shaped grooves form a square channel in a microwave box, a bamboo-wood glued rod composed of four bamboo pieces and a square wood core is delivered from a feeding channel port, the bamboo-wood glued rod is pressed by one sides of the multiple pairs of rollers with V-shaped grooves, and the other sides of the multiple pairs of rollers with the V-shaped grooves drive the bamboo-wood glued rod to move forwards. A plurality of microwave tubes arranged at the top of the microwave box transmit microwave to heat the adhesive application face of the bamboo-wood glued rod till an adhesive layer is solidified, and the bamboo-wood glued rod is discharged from a discharging channel port by the rollers with V-shaped grooves. The operation time of the bamboo-wood glued rod in the microwave box can be controlled by regulating the rotating speed of the speed regulating motor.

Description

technical field [0001] The invention relates to a gluing device for composite bamboo and wood, in particular, a composite rod of bamboo and wood is fed in from the feeding passage, clamped, moved forward and heated until glued and then sent out from the discharge passage. Continuous gluing unit. 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.

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.
