Abstract

The invention relates to the field of cutting blades, in particular to a rotary knife device capable of automatically compensating. The rotary knife comprises a blade, a knife flywheel, a mounting base and a bearing base, wherein the mounting base and the knife flywheel are fixedly arranged; the mounting base and the bearing base are connected to a rotary shaft through bearings; the bearing base and the mounting base define a cavity; at least two thrust parts are arranged in the cavity for pushing the bearing base; and the bearing base drives the rotary shaft to move in a direction away from the mounting base, so that the blade is pushed to perform automatic compensation on the knife flywheel, and therefore, problems such as poor cutting quality and part damages caused by gaps generated byblade cutting abrasion are solved.

Description

technical field [0001] The invention relates to the field of cutting blades, in particular to a rotary knife device capable of automatic compensation. Background technique [0002] In the existing cutting equipment, it includes a blade and a cutter head. The blade is a movable knife, and the cutter head is a fixed knife. ; The blade rotates relative to the cutter head to form a cutting of the material. During the cutting process of the movable blade, the edge of the knife that contacts the cutter head will be worn accordingly. After the movable blade is worn, a gap will be formed between the movable blade and the cutter head, which will affect the cutting effect and the life of the blade. In the prior art, after the cutting blade wears, manual adjustment is required to compensate for the wear. This method of compensating wear is not only cumbersome to operate, but also needs to be carried out in a shutdown state to ensure safety; therefore, there are defects that the equip...
