Description

Technical Field

[0001] This invention relates to a bamboo-based engineered wood panel production equipment, and more particularly to an automatic batch assembly equipment for laying multiple bamboo curtains in parallel. Background Technology

[0002] In the bamboo-based engineered wood panel industry, radial bamboo blinds, as a core substrate, are the most commonly used basic material in bamboo-based engineered wood panel production due to their wide availability of raw materials, high material utilization rate, and strong processing adaptability. Structurally, radial bamboo blinds are woven from parallel radial bamboo strips. In the crucial process of assembling and laying the bamboo-based engineered wood panels, significant laying defects are easily caused. Because the bamboo strips are arranged in a single direction and the blinds are highly flexible, problems such as layer stacking and misalignment can easily occur during manual or conventional equipment installation. This directly affects the stability of subsequent hot-pressing processes, leading to uneven thickness, large strength fluctuations, and other quality issues in the finished bamboo-based engineered wood panels, thus hindering the improvement of product quality.

[0003] From the current state of industry production, existing bamboo curtain designs are based on the length and width specifications of the target bamboo-based engineered wood panels, meaning the bamboo curtain dimensions match the finished panel dimensions. While this size matching method meets basic production needs, it still has significant limitations in the installation process. Currently, the industry commonly uses a manual method of laying out individual bamboo curtains layer by layer. Operators need to pick up and place each curtain one by one and adjust its position. This not only requires a high level of operator skill but also results in extremely low installation efficiency, making it difficult to meet the needs of large-scale, mass production of bamboo-based engineered wood panels.

The hook-off conveying unit is used to convey the dried bamboo curtains to the rolling unit, which rolls the conveyed bamboo curtains into a bamboo curtain roll. The hoisting and rolling unit is used to hoist and convey the bamboo curtain roll to the unrolling unit, which unrolls the bamboo curtain roll and transmits the unrolled bamboo curtain to the laying unit via the suspension and buffer unit. Multiple bamboo curtains are then laid flat and stacked on the laying unit, and the laying unit transmits the stacked bamboo curtains to the cutting machine for fixed-length cutting.

The movement speed of the mesh conveyor 61 and the bamboo curtain 10 are set on the control cabinet 08. The cutting length of the bamboo-based engineered wood blank is determined by the setting of the unwinding motor 423. The unwinding motor 423 is started, causing the bamboo curtains 10 on each bamboo curtain roll to move sequentially from the gap between the first unwinding roller 421 and the second unwinding roller 422, and the buffer rod 53 to the longitudinal rod 512, and then paused. Wood veneer is placed at the right end of the mesh chain conveyor 61, and the cutting machine 07 is started. The laying motor 62 is started to make the mesh chain conveyor 61 run, and then each unwinding motor 423 is started to move each bamboo curtain 10 and stack them in parallel on the mesh chain conveyor 61 to form a blank. Before the blank is cut, wood veneer is laid on the top bamboo curtain 10, and then the cutting machine 07 cuts it into bamboo-based engineered wood blanks of the preset specifications according to the set length. This process is repeated to realize the automatic batch assembly of multiple bamboo curtains 10 in parallel and then cut them into bamboo-based engineered wood blanks of the preset specifications for mass production.
