Furthermore, when the movable knife rotates, the double tips on the main cutting edge firstly puncture continuous reconstituted tobacco leaves, then the arc-shaped cutting edge gradually passes through the fixed knife in the rotation process to form shearing on the continuous reconstituted tobacco leaves, and the regular hexagon reconstituted tobacco leaf products are cut through the staggered cutting of the two rows of adjacent movable knives.

The invention also discloses a regular hexagon reconstituted tobacco slitting cutter suitable for continuous processing, wherein the movable cutter comprises a mounting part at the bottom and a cutting part at the upper part, the front projection of the cutting part is in a trapezoid shape, the side projection of the cutting part is in an arc shape that a cutting edge is gradually bent towards the rolling direction of the movable cutter, and the middle part of the cutting part is provided with at least one flow guide opening with a through front surface and a through back surface; one side of the cutting edge facing the cutting surface is provided with a diversion trench communicated to the diversion port; the end face of the cutting edge is a plane and the back side of the cutting edge is a straight line side.

Furthermore, the cutting edge is formed by intersecting three connected cutting planes with trapezoidal projection shapes and an inwards concave arc-shaped cutting curved surface to form a double-pointed arc-shaped main cutting edge.

Furthermore, the guiding gutter is the arc guiding gutter of the arc cell type of indent, and the summit of the both sides limit of arc guiding gutter and the summit coincidence of cutting edge both sides end for the overlooking projection of cutting edge is that the cutting edge is crescent camber linear, relative back limit is sharp.

Furthermore, the depth of the arc groove of the guide groove is gradually deepened from the top of the cutting edge to the lower part until the arc groove is communicated with the guide port.

Furthermore, the diversion port is a polygon with an approximately trapezoidal shape; the area of the single sheet is larger than that of the regular hexagon reconstituted tobacco product, and the regular hexagon reconstituted tobacco product can smoothly pass through the single sheet in the cutting process.

Furthermore, the front projection of the cutting part is in an isosceles trapezoid shape, the installation part is in a rectangle shape, the movable knife is integrally formed, and the flow guide opening is in a polygon shape similar to the trapezoid shape.

Furthermore, an inclined guide corner edge is arranged on the edge of the inner side of the guide opening of the movable cutter.

The working principle of the invention is introduced:

the movable knives are arranged on the movable knife roller and are arranged side by side along the transverse direction according to a specific interval, the movable knives on two adjacent rows in the front and back are arranged in a staggered mode, the fixed knives matched with the movable knives for cutting are further arranged on the cutting surface, the size of the cut of each fixed knife is matched with the size and the specification of the blades of the movable knives and the shape and the size of a material to be cut and formed, the reconstituted tobacco paper is fed obliquely upwards, the fixed knives positioned behind the reconstituted tobacco are matched, the reconstituted tobacco finished product in a regular hexagon is just cut under the cutting of the two adjacent rows of movable knives, and then the discharging is finished under the movable knife roller. In the prior art, the shape of the finished product after cutting is an approximate hexagon with convex and concave edges instead of a regular hexagon due to the inward bending of the blade part; on the other hand, through a plurality of experiments, the inventor finds that in the prior art, the blade does not have an opening, although the blade edge part is bent inwards, turbulence is generated at a cutting part due to airflow generated by the blade in the operation process of the equipment, the turbulence influences the probabilistic shaking of fed paper, the cutting amount is changed, the cutting shape is changed, the blade is not designed with the opening, the whole process is similar to a fan, the airflow is generated, the cutting rotating speed is limited, and the torque force and the power consumption cost of the motor are increased. In the design of the moving knife structure, firstly, the front and the back of the knife surface are provided with the through flow guide ports, so that air flow in the rotating process can be effectively discharged along the flow guide ports, air turbulence in the cutting process is reduced, and products can stably and orderly advance; secondly, a diversion trench communicated with the diversion port is arranged on one side of the cutting edge facing the cutting surface, so that the air flow met by the cutting edge part can be drained from the diversion trench to the diversion port to be discharged, in the moment of cutting the movable cutter and the reconstituted tobacco, local air between the cutting edge and the surfaces of the reconstituted tobacco leaves can be guided by the guide grooves, and cannot flow to the direction of the reconstituted tobacco leaves to cause air flow change to cause paper web deformation or lifting of the reconstituted tobacco leaves, so that the stability and cutting tightness of the cutting part are ensured, the probability of incomplete cutting and cutting in the cutting process is reduced, the regularity and consistency of the shape of a finished product are improved, crushed material and crushed foam in cutting are effectively prevented from being adsorbed and adhered to the movable cutter body, the adhesion amount to materials is reduced, the times of cleaning the movable cutter body by manual shutdown are reduced, and the continuous production is facilitated; meanwhile, the groove structure of the diversion trench also enables the overlooking projection of the cutting edge to be in a crescent arc shape, the opposite back edge is in a straight line shape, namely one side facing the cutting surface is in a crescent arc shape, and the cutting edge is matched with the bending arc shape of the upper cutting edge part, so that the sharpest cutting edge parts at the two ends of the cutting edge firstly puncture the paper surface of the reconstituted tobacco at the cutting moment and then gradually contact with the whole cutting edge to finish one-time cutting, thereby forming a point-to-surface cutting process, realizing the process of concentrating the cutting resistance of the cutting edge and the paper into local dispersion and then summarizing, effectively buffering the friction stress dispersion mode of the cutting edge during cutting, prolonging the service life of the cutting edge in continuous work, and enabling the air flow compressed by the rotation of the cutting edge to be discharged from the diversion trench to the diversion port along with the trend in the process, so that the cutting process is accurate and complete; finally, due to the design of the diversion trench, the other side of the knife edge, namely the back side of the knife back, can be designed in a linear manner, so that the cutting top side of one of the two cutting oblique sides of the whole knife edge is ensured to be a regular trapezoid formed by the linear type, and a complete regular hexagon shape is formed by a piece of material cut by the two movable knives.
