[0049] The specific working process of this utility model:

[0050] The sawing machine is started through the control console 4, and the lifting assembly is started to raise the band saw mechanism 3. Specifically, the motor 206 is started, and the transmission shaft 201 is driven to rotate through the motor 206. The transmission shaft 201 drives the chain 205 through the sprockets 202 at both ends to move along the sprocket 3 204 and the sprocket 4 208. The chain 205 drives the saw table 301 to slide upward along the saw frame 2.

[0051] Then, the driving assembly is started, so that the saw frame 2 is located on one side of the bed 1, and the teeth of the woodworking band saw blade 304 are facing the direction of the wood. Specifically, the motor 211 is started, the motor 211 drives the transmission shaft 207 to rotate, and the transmission shaft 207 drives the sprockets 4 208 at both ends to rotate. After the sprocket 203 drives the chain 209 to pass through the sprocket 5 210, the two ends of the chain 209 are respectively connected to the two ends of the bed 1. Under the constraint of the sprocket 5 210, the traction force generated by the chain 209 drives the saw frame 2 to move forward along the bed 1.

[0052] The sawing machine is reset through the operation of the above lifting assembly and driving assembly;

[0053] The wood is placed horizontally on the bed 1 and fixed, the lifting assembly is started to drive the band saw mechanism 3 to descend, and then the driving assembly is started to drive the saw frame 2 to move forward along the bed 1, so that the woodworking band saw blade 304 of the band saw mechanism 3 on the saw frame 2 cuts the wood. When cutting, the side of the woodworking band saw blade 304 abuts against the side of the band saw blade guide wheel 1 309 and the band saw blade guide wheel 2 311, and the edge of the non-serrated side of the woodworking band saw blade 304 abuts against the stop 312 respectively. Through the setting of the limiting device, on the one hand, the deformation of the woodworking band saw blade 304 caused by the longitudinal pressure of the wood is reduced, and on the other hand, the up and down vibration and jumping of the woodworking band saw blade 304 when sawing wood are reduced, and the woodworking band saw blade 304 cuts wood more stably and reliably;

[0054] The chip discharge port 3081 opened on one side of the protective cover 308 serves to discharge wood chips. When a layer of wood is cut, the lifting component is started to drive the band saw mechanism 3 to rise, and then the saw frame 2 is moved to the edge of the wood through the driving component. The lifting component is started again to drive the band saw mechanism 3 to descend to cut the next layer of wood, and finally the cutting of the entire wood is completed.

[0055] By combining the bed 1 and the chain 209, under the constraint of the sprocket 5 210, the saw frame 2 and the bed 1 are more closely fitted, avoiding the roller 222 of the saw frame 2 from separating from the bed 1, and the movement of the saw frame 2 is more stable, so that the woodworking band saw blade 304 of the band saw mechanism 3 can cut the wood more stably and quickly, thereby improving the processing efficiency of the sawing machine.
