Background

In the prior art, logs are cut into sections by a cutting saw and then are sent into a rounding machine through a conveying device, the rounding process is to cut off the convex parts, the crust parts or the bent parts of the log sections, and finally the log sections are cut into standard cylinders in a rotary cutting mode, so that the slabs which are convenient for subsequent rotary cutting are unified in phase and standard.

However, in the process of rounding, because the log is provided with knots or bends, the wood section cannot rotate in the axial direction, the resistance generated thereby is large, the problem that the wood section cannot rotate often occurs, the positions of the machine and the wood section need to be adjusted repeatedly, the operation is laborious and time-consuming, the traditional rounding design structure is too complicated, the later maintenance is also very inconvenient, no power part is used for providing power for the lifting roller, the wood section only depends on the clamping roller on the tool apron to clamp and rotate, once the shape of the wood section is irregular, the joint area between the clamping roller and the wood section is small, the grabbing force is low, and therefore the phenomenon that the wood section stops rotating can occur.

The plate needs to be cut in a corresponding size after being rotationally cut, and the commonly used cutting size is 75mm wide. At present, all collect the pile up neatly and carry out corresponding size cutting after turning the log into whole slab, whole process procedure is more, and the slab is collected repeatedly and is transported also very inconvenient.

In addition, when the Europe pine plate is produced, a scattering device is needed to scatter and crush the plate, and the plate is scattered into small wood chips with the width of 5-20mm, the existing scattering device is complex in structure, inconvenient in dismounting and maintenance process, long in consumed time, high in failure rate and high in maintenance cost, and normal production progress is influenced, and the production capacity is seriously influenced.
