Manufacturing method of woodworking band saw machine

Band sawing machine is a kind of sawing machine which uses endless belt saw blade as sawing tool and moves continuously and linearly in one direction around two saw rotation systems to cut wood. The machine body is welded by cast iron or steel plate. Therefore, band sawing machines are expensive, heavy, small in space, small in sawing width and limited in use. In particular, the saw wheel of large woodworking saw machine is easy to be damaged, and the sawing speed and efficiency of band saw machine are not as good as that of table saw machine.

Technical implementation elements: The purpose of the utility model is to provide a woodworking band saw machine to solve the problems of high cost, heavy weight and large occupied space of the band saw machine proposed in the background technology, with small cutting width, limited use and low efficiency. In order to achieve the above purpose, the invention provides the following technical scheme: a band saw comprises a guard, a saw wheel, a belt pulley, a tension ring, a saw shaft, a driven pulley, a rod lifting sleeve, a compression spring double pipe, a motor, an air cylinder, a speed reducer, a circular thrust plate, a hand wheel, the back plate and the traveling wheel, wherein the inner guard ring is fixed to the saw, the saw surface mounting wheel tension ring and the inner tension ring are fixed pulleys, and are connected to the shaft and the driven pulley through sawing at the guard. The lifting sleeve is fixed on a double-rod compression spring tube, the double-layer tube and a compression spring are arranged at the left end above the driven pulley, the right electric motor side cylinder is installed, a circular thrust plate is arranged at the left end of the gear unit and the upper circular plate and is connected to the push rod sleeve downward, the back plate is provided with a hand wheel downward, and the lower part of the driving wheel of the fixed shield is provided. Preferably, the shield is a sound insulating material. Preferably, the sliding stroke of the pulley coincides with the sliding stroke of the saw wheel cutting saw. Preferably, that piston rod end of the double tube compression spr is fixed to the lif sleeve. Preferably, the circular push plate is connected with the hand wheel through a self-locking body.

Compared with the prior art, the utility model has the advantage that the woodworking band saw machine is equipped with a double-tube compression spring to assist in adjusting the inclination angle and has the function of automatic adjustment. High efficiency and fast tension ring saw wheel can be used to quickly adjust and tension the saw wheel. When the saw blade moves backward, it plays a limiting role, does not cause the saw blade to fall off, meets the use requirements, expands the cutting range, improves the economic benefits, changes the traditional large-volume working mode into "gas-electricity integration", reduces the weight of the vehicle body, simplifies the structure of the vehicle body, and simplifies the assembly difficulty.
