Description

Technical Field

[0002] Through the coordinated work of saw blades, motors, workbenches and other components, sawmills are able to cut wood accurately and quickly to meet the needs of furniture manufacturing, construction, shipbuilding and other fields. For example, in the furniture manufacturing industry, sawmills can saw, cut, and plan wood to make raw wood into various shapes, which is convenient for manufacturing furniture and other products.

[0003] In order to facilitate the transportation of cylindrical wood, an inclined feeding rack is now set up, and the wood automatically slides down along the inclined surface or slide of the feeding rack under the force of gravity. However, most of the existing feeding racks are just a U-shaped trough, so it is difficult for the feeding rack to ensure that the wood remains stable during the sliding process, and the wood is prone to deflection or rolling; when the wood slides under the force of gravity, it may cause friction with the feeding rack, and the wood needs to be clamped and fixed during cutting, which can easily cause damage or scratches on the surface of the wood, affecting the quality of the wood. Therefore, we propose a gravity-fed sawmill with a feeding rack. Summary of the invention
