Problems solved by technology
[0002] The existing rotary cutters are fixed directly on the body of the rotary cutter by screws. The cutter body has a groove at an interval of about 15 cm along its width direction. The direction of the knife edge extends to half of the knife body. With the wear of the knife edge, loosen the screw to lift the knife body upward. Because there are too many grooves on the knife body, the rigidity of the knife body is greatly reduced, and the knife body is easy to use during use. Twisted into a wavy shape, the screws cannot be adjusted in a straight line, making the peeled wood chips wavy and uneven, with uneven thickness

The present invention relates to log rotary cutting machine, and is especially rotary cutter fixing mechanism for log rotary cutting machine. The cutting body is fixed onto one cutter holder, the cutter holder has one sloped upper end in the shape of cutter edge and one bottom bent to form a right angle for the cutter back to be pressed on, and one cutter height regulator is set between the cutter back and the right angle of the cutter holder. The present invention has simple and reasonable structure, no damage on the cutter rigidity, convenient and accurate cutter height regulation, convenient cutter installation and capacity of rotary cutting flat and homogeneous timber sheet.
Description
technical field [0001] The invention relates to a log rotary cutter, in particular to a fixing mechanism for the rotary cutter of the rotary cutter. Background technique [0002] The existing rotary cutters are fixed directly on the body of the rotary cutter by screws. The cutter body has a groove at an interval of about 15 cm along its width direction. The direction of the knife edge extends to half of the knife body. With the wear of the knife edge, loosen the screw to lift the knife body upward. Because there are too many grooves on the knife body, the rigidity of the knife body is greatly reduced, and the knife body is easy to use during use. It is twisted into a wave shape, and the screws cannot be adjusted in a straight line, so that the peeled wood chips are wavy and uneven, and the thickness is uneven. Contents of the invention [0003] Therefore, the purpose of the present invention is to provide a long service life, convenient adjustment of the knife body, firm ...
