Abstract

The invention discloses a fiber short cutter roller capable of adjusting a cut-in angle of the cutter in stepless mode. The fiber short cutter roller comprises an I-shaped cutter roller, two angle discs with the same structure, two positioning discs with the same structure and stair shafts, wherein the I-shaped cutter roller is installed in the middle of the stair shafts and fixedly connected with the stair shafts, and the angle discs, the positioning discs, sleeves and bearings are sequentially installed on the stair shafts outside two ends of the I-shaped cutter roller outwards. By means of the design of the angle discs and a rotary cutter groove, the cut-in angle of the cutter can be adjusted in stepless mode, and after the device is installed, the cut-in angles (ranging from 0 degree to 30 degrees) of all long blades can be adjusted by rotating the angle discs in one step, further the cut-in angles of all the long blades are ensured to be same, the problem that the existing short cutting devices cannot adjust the cut-in angles is solved, the short cutting effect is improved, service life of the cutter is prolonged, and production cost is reduced.

Description

technical field [0001] The invention relates to a fiber cutting device, in particular to a fiber chopped cutter roller capable of steplessly adjusting the cutting angle of the cutter. Background technique [0002] At present, although the chopping equipment used in the actual production of various fiber chopped strands has various structures such as pressure wheel type, groove wheel type, and groove plate type, their cutting forms are basically the same, that is, the cutting edge of the knife is parallel to the fiber filaments. The radial cut, that is, the cut angle is 0°. Existing studies have shown that when the cutting edge of the tool cuts in at a certain angle to the radial direction of the fiber filament, it can have a better chopping effect, and the cutting angle varies with the fiber to be cut. For example, Yuan Yigao, Zhu Shigen and others found in the research on the edge angle of the chemical fiber cutting knife that when cutting polyester semi-dull fiber, when t...
