Abstract

The utility model relates to a tobacco machine special purpose cutting device, particularly a knife roller used on a tobacco cutting machine. The present spur type knife roller generates pulsating impact when cutting, has big cutting resistance and big vibration and is unfavorable for cutting quality. The utility model is formed by that a space angle which is more than zero DEG but less than 90DEG is formed between a cutting edge line before a sharpened knife blade and a shaft line of the knife roller body, wherein, the space angle which is bigger than zero DEG but less than 90DEG is arranged between a plane on which the knife blade is arranged and a cylindrical tangent plane of the knife roller body, the cutting edge is gradually cut into a 'tobacco cake' in a way of point contacting in the process of cutting, and the cutting process is in the form of spiral and roll cutting. Thus, the purpose of light, fast, and stable cutting is realized; besides, the tobacco cutting quality can be improved.

Description

Cutting tobacco machine with revolving knives

The utility model is a used rotor on the special-purpose throwing equipment of tobacco machine-hobboing cutter filament cutter.

Present existing hob type filament cutter (as YS14, the YS44 type of domestic production), the cutting edge of the blade 2 on its roller cutter body 6 is parallel with the axis 1 of roller cutter body, and plane, blade place is parallel with the section of roller cutter body cylinder, is spur type rotor (see figure 1).When this kind rotor was cut pipe tobacco, the blade cutting edge total length was cut " cake " simultaneously, and is many blade owing to being equipped with on the rotor, produces pulsatile impact during cutting, and cutting resistance is big, and vibration is big, and is unfavorable to the chopping quality.

The purpose of this utility model is to overcome the shortcoming of existing rotor, provides a kind of cutting resistance and vibration are reduced, the spiral hobboing cutter filament cutter rotor that the chopping quality improves.

Structure of the present utility model is as follows: be provided with one or one above blade on a roller cutter body, cutting edge line before the Sharpening a knife blade and roller cutter body axis are greater than the space angle of cut of zero degree less than 90 degree, and the section of plane, blade place and roller cutter body cylinder also is greater than the space angle of cut of zero degree less than 90 degree.

During the rotor rotation, the knife sharpener that moves back and forth along the rotor axis direction tempers blade, its sharpening face forms helicoid, helical cutting edge is in the chopping process, cut " cake " gradually with a way of contact, working angles is the spiral and roll cutting formula, thereby realizes the purpose that cutting is brisk, steady, can improve the chopping quality.

The structure of optimization of the present utility model is the space angle of cut that preceding cutting edge line of Sharpening a knife blade and cutter rod body axis are the 2-10 degree, and the section of plane, blade place and roller cutter body cylinder is the space angle of cut of 1-4 degree.

Compare with prior art, the utility model has the advantages that can improve the chopping quality reduces power consumption.

Fig. 1 is a spur type rotor structural representation.

Fig. 2 is an embodiment rotor structural representation sketch, and wherein (a) is main looking, and (b) for the A-A of (a) figure analyses and observe, (C) analyses and observe for the B-B of (b) figure.

Fig. 4 is the shape schematic diagram behind the embodiment Sharpening a knife blade, and wherein (a) is main looking, and (b) looks for a left side.

Embodiment: see Fig. 2-4,8 blades 2 are housed on the roller cutter body 6, every cutting edge line before the Sharpening a knife blade and roller cutter body axis 1 are the 5 degree space angles of cut, every section plane, blade place and roller cutter body cylinder is the 2 space angles of cut of spending 26 fens.Blade in use, can diminish gradually because of wearing and tearing make the cutting external diameter of rotor, so in the rotor cutting, blade needs feed and grinding cutting edge gradually, for guaranteeing that cutting edge is sharp and the helical cutting edge cutting diameter is constant, the spy drives left and right push broach

spiral shell pieces

4 and 7 by the left and right push

broach screw mandrel

3 and 5 that is located at the blade back and promotes the blade feed synchronously.

Claims
