Description

The cutter that tobacco bale is cut

Technical field

The utility model belongs to the machine for processing tobacco technical field, is specifically related to the cutter of tobacco bale cutting machine in the production of cigarettes.

Background technology

Be used for the cutter that tobacco bale cuts at present and mostly be straight line edge, this cutting edge is when cutting, and descending cutting resistance is big, causes the cutting knife sharpening cycle short, and the knife rest of equipment is yielding.Simultaneously, cooperate unfavorable defective because the cooperation of cutting knife cutting edge and cutting knife plate exists, it is descending not in place blade to occur, cuts the phenomenon of back cigarette piece adhesion, thereby causes material poor continuity in the processing procedure of follow-up equipment, even influence moisture regain effect.And back cigarette piece adhesion appears cutting sometimes, and cause the cigarette piece to be stuck between stirring arm and the conveyer belt, need manually get rid of, cause and cut the back discontinuous problem of cigarette piece and certain potential safety hazard.On the other hand, because the improvement of tobacco cutting technology, increased the thin slice tobacco bale in the tobacco bale of cutting, this tobacco bale is bigger to the descending resistance of cutting knife, the wearing and tearing of tool setting are also more serious, for overcoming this defective, only adopt the mode that increases cutting force to come a minute shave tobacco bale at present, but increased the maintenance of equipment.

Summary of the invention

The purpose of this utility model is intended to overcome the defective of prior art, provides a kind of and avoids cutting back cigarette piece adhesion, and can realize cutting back cigarette piece constant current and export, and the cutter that the tobacco bale of potential safety hazard is cut is stopped in the normal operation of assurance equipment.

The cutter that tobacco bale described in the utility model is cut, constitute by cutting knife and stirring discharging cutting knife plate, the cutting edge of cutting knife is a zigzag, article two, the junction of oblique line cutting edge forms the point of a knife point, by the oblique line shape toothing cutting edge more than 2, the downside of cutting knife is provided with stirring discharging cutting knife plate, and the upper surface of cutting knife plate has edge of a knife body.

The angle [alpha] of the cutting edge oblique line of described cutting knife is 0.1-20 °, and the quantity of point of a knife point is 1-20.

The upper surface of described cutting knife plate has edge of a knife body, and edge of a knife shape is corresponding with cutting knife oblique line blade shape.

Described cutting knife is made by alloy material Cr12MoV.

Cutting knife cutting edge of the present utility model adopts cross hatching, big zigzag fashion cutting edge, and forming pointed point of a knife with the infall of oblique line cutting edge is the main impetus of cutting knife, and the angle of oblique line and horizontal plane is 0.1-20 °, and whole quantity cutter upper slitter cusp is that 1-20 is individual.The motion mode of cutting knife is the straight cigarette piece of progressively cutting down, and the contact point on the straight line edge is with progressively incision of cutting knife at this moment, cuts the cigarette piece successively, forms the cutting mode of cutting sth. askew and reaches the labour-saving purpose.As everyone knows, the blade shape of cutting knife and angle are stressed most important for the cutting article, and the cutting movement of cutting sth. askew is compared with the cutting movement of vertical cut, can reduce more active force, improves stock-removing efficiency.For realizing that cutting back cigarette piece falls into adhesion on the guide plate smoothly, the blade shape and the cutting knife of the edge of a knife groove of stirring discharging cutting knife front edge of board match, for reducing resistance, edge of a knife body sectional making.Be that assurance cutting knife plate and roller of conveyer belt external arc are not interfered simultaneously, arcuate structure is adopted in its bottom, guarantees the matching relationship of the two.

Traditional cutting knife adopts materials such as T10 more, because tobacco leaf has stronger elasticity, toughness and crush resistance, contain higher sugar and oil content, the anti-ability of cutting of tobacco leaf and to resist the resistance that is cut very big, therefore cutting knife cutting knife cutting edge when cutting increases cutting resistance very easily by the adhesion section crock, and cutting knife not only will have higher hardness and intensity, but also stronger toughness will be arranged, traditional cutting knife can not satisfy instructions for use.The utility model cutting knife adopts alloy material Cr12MoV, and carries out carburized tungsten and handle, and it is 0.6-2.0mm that notes ooze thickness, and notes ooze hardness and reach more than the HRC64.

Of the present utility model rational in infrastructure, cutting power improves greatly, has stopped the phenomenon that gets stuck, and realizes cutting back cigarette piece constant current output under control system control, and the cutting knife durability increases, and can satisfy tobacco plant slice simultaneously and cut requirement.

Description of drawings

Fig. 1 is cutting knife cutting edge and cutting knife plate structure schematic diagram.

Fig. 2 is the left view of Fig. 1.

Among the figure, 1-cutting knife, 2-oblique line, 3-point of a knife point, 4-cutting knife plate, 5-edge of a knife body.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing, but the utility model is not limited to shown in the accompanying drawing.

Embodiment 1

As Fig. 1, the cutting edge of cutting knife 1 shown in Figure 2 is made of the cutting edge that many oblique lines 2 form, and many oblique lines form the pit saw profile of tooth, forms point of a knife point 3 in the junction of oblique line cutting edge, and the angle [alpha] of oblique line is 20 °, is 4 oblique lines shown in the figure, 2 point of a knife points.Downside at cutting knife is provided with unloading arm cutting knife plate 4, and the upper surface of cutting knife plate 4 is provided with edge of a knife body 5, and edge of a knife shape is corresponding with cutting knife oblique line cutting edge, and for reducing resistance, edge of a knife body sectional is made.The edge of a knife body of the utility model by being installed in unloading arm cutting knife plate cooperates with cutting knife, cigarette piece after cutting fallen on the guide plate smoothly and no longer adhesion.

Embodiment 2

The quantity of the described point of a knife point of cutting 3 is 20, and the angle [alpha] of oblique line 2 is 0.1 °, and all the other are with embodiment 1.

Embodiment 3

The quantity of the described point of a knife point of cutting 3 is 10, and the angle [alpha] of oblique line 2 is 10 °, and all the other are with embodiment 1.
