Background
The processing of wood requires that bark is firstly stripped and then deep processing is carried out, and the stripping method of the bark generally comprises two methods of manual processing and mechanical processing; the manual bark cutting consumes a large amount of manpower, the processing efficiency is low, the bark is cleaned to generate a large number of flaws, the quality of a finished product is poor, and the requirement of modern people for high-quality life cannot be met; the existing main stream method is to remove bark by machining, and the rotary cutter adopted by the existing machining generally consists of a frame, a static cutter head and a feeding mechanism with a movable cutter head, wherein the feeding mechanism moves left and right relatively on the frame under the action of a gear rack and a gear motor. Due to the cooperation gap between the gear rack and the gear motor, the distance between the two ends of the static cutter disc and the movable cutter disc has errors, and the round log is subjected to rotary cutting to have a big end and a small end. Therefore, improvements are needed.
The chinese national intellectual property office discloses a utility model patent that patent number is ZL2018207833024, this scheme includes the base etc., and a plurality of support frames all are located the base bottom, and a plurality of protection shields are all on a support frame, and the mount is fixed on the movable plate, and the ventilation hole is on the rotary-cut case, and wherein the rotary-cut case includes box etc. the fan is located the top of the inside of box, and a plurality of rotary-cut saw bits are located the inside both sides of box respectively, leading board is located the front of box, and rotatory jogged joint is on leading board, and a plurality of blades all are located the rotatory downthehole.
