Rotary cutting machine capable of changing thickness of rotary cutting veneer through automatic stepless gear shifting of cam

Abstract

The invention discloses a rotary cutting machine capable of changing the thickness of a rotary cutting veneer through automatic stepless gear shifting of a cam, and relates to the technical field of wood processing. A double-row roller assembly, a double-row roller feeding assembly and a knife body base are installed on a rack, the double-row roller feeding assembly is used for driving the double-row roller assembly to move towards or away from the knife body base, and a supporting arm is hinged to the end, close to the double-row roller assembly, of the knife body base through a supporting shaft. The end, away from the double-row roller assembly, of the knife body base is provided with a cam assembly. The cam assembly is used for driving the supporting arm to rotate. A single-row roller pressing ruler assembly is arranged on the supporting arm. A locking adjusting assembly is used for adjusting the position of the single-row roller pressing ruler assembly on the supporting arm. A rotary cutter is installed on the upper portion of the end, close to the double-row roller assembly, of the knife body base. The double-row roller assembly, the double-row roller feeding assembly, the single-row roller pressing ruler assembly and the cam assembly are all connected with a controller. According to the device, automatic changing of any rotary cutting thickness can be intelligently and accurately achieved, knife height and knife seam standards are fixed at a time and are not changed, and therefore labor and time are saved.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a rotary cutting machine 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....
