Embodiment Construction

[0020] In order to make the objectives, technical solutions, and advantages of the present invention clearer and clearer, the following further describes the present invention in detail with reference to the drawings and embodiments.

[0021] An embodiment of the present invention provides a sawing device, such as figure 1 As shown, it includes a frame 100, a driving wheel 200 arranged at the lower end of the frame 100, and a driven wheel 210 arranged at the upper end of the frame 100. The frame is made of cast iron or steel plate welding. The driven wheel 210 is arranged in parallel with the driving wheel 200 and is used for assembling a saw blade 300 for sawing wood. The driving wheel 200 is driven to rotate by the motor 110 and is adapted to rotate with the driven wheel 210 through the saw blade 300. Preferably, the weight of the driven wheel arranged at the upper end of the frame 100 should be 2.5-5 times lighter than the weight of the lower driving wheel; the cutting speed ...

Abstract

The invention discloses a timber-sawing device. The device comprises at least two pairs of driving wheels and driven wheels, and the driving wheels and the driven wheels are in concentric coaxial connection respectively, wherein the diameter of a first pair of driving wheel and driven wheel is greater than that of a second pair of driving wheel and driven wheel; the other pairs of driving wheels and driven wheels are arranged in turn along the concentric coaxial position of the first pair of driving wheel and driven wheel; and a saw blade tensioning mechanism used to ensure the stable tensioning degree of a saw blade during operation and a belt distance regulator used to regulate the saw blade to move along a vertical slide rail are arranged between the driving wheels and the driven wheels. As at least two pairs of driving wheels and driven wheels are adopted, when timber is cut, the timber-sawing device provided by the invention can cut a plurality of pieces of timber each time, thereby having high sawing-cutting efficiency and ensuring high size precision of the timber which is sawn and cut. The timber-sawing device is simple in structure, and as cutting size is precisely controlled by the belt distance regulator, the timber-sawing device has the advantages of ensuring high size precision of cut timber, reducing labor intensity, saving electricity cost and improving labor productivity.

Description

Technical field [0001] The invention relates to the technical field of wood processing machinery, in particular to a sawing device with multiple saw blades. Background technique [0002] At present, people generally use electric band saws or electric discs when sawing round wood into square logs, or sawing square logs into planks and wood supports. The electric band saw has a circular saw blade, and the circular saw blade Installed on a woodworking machine. When the woodworking machine rotates, it drives the circular saw blade to cut the wood. The electric circular saw installs the disc-shaped saw blade on the woodworking machine. When the woodworking machine rotates, the disc-shaped saw blade rotates. Wood is cut. [0003] However, the prior art sawing device usually only has a pair of saw wheels and one saw blade is installed, and can only cut one piece of wood at a time. The efficiency of sawing wood is low, energy is wasted, and the dimensional accuracy of the cut wood is low....
