Description
Technical Field
The invention relates to the technical field of wood processing, in particular to a rotary cutter for automatically changing the thickness of a rotary cut veneer in a stepless gear shifting manner by utilizing a cam.
Background
The current peeler in the market, the regulation mode that changes rotary-cut thickness has two: the first method is manual regulation, specifically, when a veneer with a certain thickness is set to be rotationally cut, an adjusting screw rod needs to be manually screwed to pull a single-roller pressure bar to move back and forth, the gap distance between a proper rotary cutter and the single-roller pressure bar is adjusted, and then the height of a blade is adjusted to be proper. This process requires approximately 20-30 minutes for the skilled worker to adjust. In the rotary cutting process, the rotary cutter is frequently used, the cutting edge is blunt, the rotary cutter needing to replace the ground cutting edge is not sharp, the manual debugging process needs to be repeated every time the cutter is replaced, the debugging needs skilled workers in the prior art, time and labor are wasted, and the debugging mechanical structure accounts for more than 98% of the rotary cutter. The second method is to use a numerical control permanent magnet servo mechanism for debugging, specifically, when a veneer single plate with a certain thickness is rotationally cut, the hydraulic locking device of the single-roller ruler base is manually controlled by an electric appliance to be in a loosening state, then the distance between the rotary cutter and the single-roller ruler is manually measured, the amount needing to be adjusted back and forth is calculated, an adjustment signal is input to the permanent magnet servo motor, the actual knife gap measured after the input accords with the calculated adjustment amount, and then a manual button is used for controlling the hydraulic pressing device to lock the single-roller ruler base. The mode adopts hydraulic and electric control, the time is shortened greatly compared with the prior mode, the adjustment is generally completed within 5-10 minutes, the knife height needs manual indication and adjustment, the debugging links are more and unstable, the equipment is used for a long time, and because the abrasion data between mechanical parts is unstable, the full automation and the precision can not be realized by matching with manual measurement every time.
Because the gap distance between the rotary cutter and the single roller is adjusted by utilizing the screw rod nut to rotate in the direction of translation in both manual operation and electric controller control modes, the thicknesses of the rotary cutter and the rotary-cut veneer sheet are changed frequently in the rotary-cut log working process, and therefore, the wear change of the adjusted screw rod nut cannot be measured and debugged manually. On the other hand, the veneer veneers with different thicknesses are subjected to rotary cutting, the height positions of the rotary cutting knives are different, when the rotary cut veneer is thin, the height of the cutting edge is higher relative to the horizontal center of the log, when the rotary cut veneer is thick, the rotary cutting edge is lower from the horizontal center line of the log, therefore, when the veneer veneers with different thicknesses are changed, the height of the rotary cutting knife needs to be properly adjusted, the adjusting process is complex, time and labor are wasted, and meanwhile, people with experience and technology are rare.
