Problems solved by technology
This method adopts hydraulic and electrical control, and the time is much shorter than before. Generally, the adjustment is completed within 5-10 minutes. The knife height needs to be adjusted manually. There are many debugging links, unstable, and the equipment has been used for a long time. The wear data between the time is unstable, and manual measurement is required every time, so it cannot be fully automatic and accurate
[0003] Because the above two methods, whether manual or electrical control, use the screw nut to rotate back and forth in the direction of translation to adjust the gap distance between the rotary cutter and the single roller, because in the work of rotary cutting logs , the replacement of the rotary cutter and the thickness of the veneer veneer are more frequent, so the adjustment of the wear and tear of the screw nut is inseparable from manual measurement and debugging
On the other hand, the veneer veneer of different thickness is rotary cut, and the position of the rotary cutter is different. When the veneer is thin, the height of the blade is higher than the horizontal center of the log. When the veneer is thicker, the blade is farther away from the log. The horizontal center line is lower, so that when changing veneer veneers with different thicknesses, the height of the rotary cutter should be adjusted appropriately. The adjustment process is complicated, time-consuming and laborious, and there are scarce personnel with experience and skills in this area.

The invention discloses a rotary cutting machine which utilizes automatic stepless shifting of a cam to change the thickness of a rotary cutting veneer, and relates to the technical field of wood processing. A double-row roller assembly, a double-row roller feed assembly and a knife body seat are all installed on a machine frame , the double-row roller feed assembly is used to drive the double-row roller assembly to move toward or away from the knife body seat, the support arm is hinged to the end of the knife body seat close to the double-row roller assembly through the support shaft, and the end of the knife body seat away from the double-row roller assembly A cam assembly is provided, the cam assembly is used to drive the support arm to rotate, the single-row roller press assembly is arranged on the support arm, the locking adjustment assembly is used to adjust the position of the single-row roller press assembly on the support arm, and the knife body seat is close to A rotary cutter is installed on one end of the double-row roller assembly, and the double-row roller assembly, the double-row roller feed assembly, the single-row roller pressure gauge assembly and the cam assembly are all connected with the controller. The device realizes the intelligent, precise and automatic transformation of any rotary cutting thickness, and the one-time reference of the knife height and knife seam is fixed, saving labor and time.
Description
technical field [0001] The invention relates to the technical field of wood processing, in particular to a rotary cutter which utilizes automatic stepless shifting of a cam to change the thickness of a rotary-cut veneer. Background technique [0002] For the existing rotary cutting machines on the market, there are two adjustment methods to change the thickness of the rotary cutting: the first is to use manual adjustment, specifically, when setting the veneer veneer of a certain thickness, it needs to be manually twisted Adjust the screw to pull the single-roller pressure gauge back and forth to adjust the gap distance between the rotary cutter and the single-roller pressure gauge, and then adjust the blade height to a suitable value. This process takes about 20-30 minutes for skilled workers to adjust. In the rotary cutting process, the rotary cutter is often used, the blade is blunt and not sharp, and the rotary cutter with a sharpened blade needs to be replaced. Every ti...
