What are the new equipment for sanding the surface of plywood
Sanding the surface of plywood is a key process for improving the flatness, thickness accuracy, and decorative effect of the board. With technological iteration, new sanding equipment has achieved breakthroughs in efficiency, accuracy, and environmental friendliness. The mainstream types and innovative points are as follows:
1. Broadband sanding machine
Using 650-1300mm wide sand belt, suitable for processing large-sized boards such as furniture and architectural decoration. The three sand frame structures (coarse sand, medium sand, fine sand) can achieve single fixed thickness sand cutting, with thickness deviation controlled within ± 0.3mm, and efficiency increased by 30% compared to traditional equipment. Some models are equipped with pneumatic segmented pallets, which are adjusted by airbag pressure to adapt to different hardness woods, avoiding sand belt slippage or excessive wear.
2. Double sided sanding machine
The upper and lower sanding belts run synchronously, achieving simultaneous sanding of both sides of plywood, doubling the efficiency compared to single-sided equipment. Built in automatic cotton cleaning device, which removes residual dust and reduces secondary pollution by rotating the brush. Some models are integrated with PLC control systems, which can preset parameters such as sand belt pressure and feeding speed, and are suitable for 3-80mm thickness plates.
3. Intelligent correction sanding machine
Equipped with micro switches and jet devices, real-time monitoring of the axial offset of the sand belt and automatic correction, with the offset controlled within 15mm to avoid sand belt breakage or detachment. Using SKF bearing and dynamic balance testing technology, the roller accuracy reaches 1-3g, reducing the risk of vibration ripple.
4. Environmentally friendly sand molding machine
Integrated pulse dust removal system recovers over 90% of dust through cyclone separator and filter bag, with an emission concentration of less than 30mg/m ³. Some models use water-cooled sanding belts to reduce grinding temperature, minimize resin clogging of sand gaps, and extend the lifespan of sanding belts.
