Background

Wood is a material which is frequently used in current furniture, buildings and the like. When the wood is used, the wood is generally required to be cut, and after the wood is cut, other processes such as assembly are carried out, so that a product is finally formed, and cutting equipment is required in the wood cutting process.

As shown in figure 1, the existing device for cutting the wood beam into the required length is that the wood beam is fed along the V forward direction, a conveying device is driven by a servo motor M1 in the feeding process, when the position of the wood beam is determined by a sensor C1, a cutting tool is driven by the servo motor M2 through a cam link device to bounce and cut the wood beam under the command condition, the size of the cut wood beam is given by a PLC pulse signal and then is determined by a conveying device controlling servo driving, but the precision tolerance of the cut size mainly depends on the stagnation position of the wood beam on the conveying device.

As shown in fig. 1, the flitch is detected by the sensor C1 and should be stopped at the B position, but since the surface roughness of the flitch is not uniform and is accompanied by different degrees of deformation, the position of the stopped flitch is between a-C, and an error is formed. In addition, during the sawing process, the cutting tool must make a pulse-type bouncing reciprocating motion, the feeding speed is substantially limited by the time difference of the bouncing and falling actions of the cutting tool, and the intermittent feeding greatly influences the processing amount and cannot obtain a processing part with accurate size. Therefore, a lateral feeding batten chopping saw capable of freely and multi-segment positioning is needed.
