Detailed Description

The invention is described below with reference to the accompanying drawings and examples.

As shown in the attached drawings, a full-automatic intelligent feeding, centering, rotary cutting and stacking veneer processing production line is provided with a frame 1 and a control device, the control device adopts a PLC controller, a log transverse conveying device 2, a stepped stepping wood feeding device 3, a log automatic centering device 4, a log automatic rotary cutting device 5, a veneer conveying device 211, a veneer automatic shearing device and a veneer automatic stacking device 7 which are connected are sequentially arranged on the frame 1, a log automatic transfer device 6 is arranged between the log automatic centering device 4 and the log automatic rotary cutting device 5, the log transverse conveying device 2, the stepped stepping wood feeding device 3, the log automatic centering device 4, the log automatic rotary cutting device 5, the veneer conveying device 211, the veneer automatic shearing device, the veneer automatic stacking device 7 and the log automatic transfer device 6 are respectively controlled by the control device, the structures and patent numbers of the transverse log conveying device 2 and the stepped stepping wood feeding device are as follows: 2013106825889, the patent names: the structure of the stepped stepping log feeding machine is the same, the log automatic rotary cutting device 5 adopts a clamping and non-clamping integrated rotary cutting device, the structure is the same as the prior art, which is not repeated, N layers in the veneer conveying device 211 can be one layer, or an upper layer, a lower layer or an upper layer and a lower layer can also be adopted, so that N layers respectively convey veneers cut by the N logs in a rotary mode, when the veneer conveying device is the upper layer, the lower layer or the upper layer and the lower layer, veneer conveying devices of other layers at the upper part of the first layer are respectively butted with a conveying frame in the veneer automatic cutting device through a veneer flow guide device, so that the logs are placed in the log transverse conveying device 2 through equipment, the control device controls the log transverse conveying device 2 to automatically feed, when the logs enter the stepped stepping log feeding device 3, the control device automatically controls the stepped stepping log feeding device 3 to automatically feed the logs into the log automatic centering device 4 through the stepped stepping log feeding device 3, a log blanking signal switch arranged on the upright post uploads information to a control device, the control device instructs a log transverse conveying device and a stepped stepping wood feeding device to continue moving, a second log is conveyed to the top end of the stepped stepping wood feeding device to wait for centering operation of the first log, meanwhile, the control device controls a log automatic centering device 4 to automatically perform rough centering and fine centering on the log, after the centering is finished, the control device automatically controls a log automatic transfer device 6 to act, the log is transferred to a log automatic rotary cutting device 5 to perform rotary cutting, and the rotary-cut veneer is conveyed by a veneer conveying device 211, cut into sections by a veneer automatic cutting device and then conveyed to a veneer automatic stacking device 7 to perform stacking treatment;
