Technical Field

[0001] This utility model relates to the technical field of wood processing equipment, specifically to an adjustable multi-blade saw for wood planks. Background Technology

[0002] Timber, commonly known as square timber, is made by sawing wood into square strips of a certain size and shape according to actual processing needs. It is mainly made of pine, linden, fir and other trees and processed into strips with rectangular or square cross sections. It is generally used for decoration and door and window materials, formwork support and roof truss materials in structural construction, or to make various wooden furniture. In the current technology, multi-blade saws are usually used for cutting. Multi-blade saws are also called multi-sided saws. Among the existing technologies, the adjustable multi-blade saw for wooden boards, authorized by announcement number CN216266530U, includes a shell, a discharge port on one side of the outer surface of the shell, a waste collection box on the lower outer surface of the shell, a fixed foot on one side of the waste collection box, an adjustable saw blade at the upper end of the waste collection box, a feed port on the other side of the outer surface of the shell, and a roller shaft inside the shell. The adjustable saw blade includes alloy teeth, a fixed post, a rotating disk, a metal saw disc, and a telescopic rod. The alloy teeth are located on the outer wall of the metal saw disc, the fixed post is located on the rear outer surface of the metal saw disc, the rotating disk is located on the rear outer surface of the fixed post, and the metal saw disc is located at the front end of the telescopic rod. In existing technologies, the position of the blade saw is fixed and cannot be infinitely adjusted, making it unsuitable for processing materials of different specifications. Furthermore, adjusting the position of the blade saw requires manual disassembly, making it impossible to quickly and accurately adjust the position of the blade saw automatically. Therefore, we propose an adjustable multi-blade saw for wooden boards. Utility Model Content
