Preferably, the concave surface 232 of the blade 23 is disposed on one side in the rotation direction. As shown in fig. 4 (a), the rotation direction of the rotating drum is clockwise. The surface of the blade 23 is provided with a certain radian, so that the scraped silk sheet material can be effectively adsorbed on the inner concave surface 231 of the blade 23.
In each preferred embodiment, the plurality of micro-holes 233 of the blade 23 are disposed in the concave surface 231 of the blade proximate the cutting edge 235.

Here, the sheet material is a material having a certain moisture content. In operation, the rotating drum 22 of the rotary blade device 5 rotates to rotate the blade 23 to scrape the sheet material off the shredded sheet material. When the blade on the rotating drum 22 rotates to the negative pressure suction area 21b of the air distribution sleeve 21, the negative pressure port 212 of the air distribution sleeve 21, the vent hole 221 of the rotating drum 22 and the inner air passage 238 of the blade 23 form negative pressure air flow, the wire sheet material scraped off by the blade 23 is immediately sucked to the concave inner blade surface 231, and when the blade 23 on the rotating drum 22 continues to rotate to the positive pressure air blowing area 21a of the air distribution sleeve 21, the negative pressure port 212 of the air distribution sleeve 21, the vent hole 221 of the rotating drum 22 and the inner air passage 238 of the blade 23 form positive pressure air flow, and the wire sheet material is separated from the surface of the blade 23 due to the loss of suction force and blown to the next station, for example, a drying treatment device performs further drying treatment.
The following is step d: the silk sheet material is dried by a fluidized drying device 7, and the dried silk sheet material is obtained. The fluidized drying device 7 conveys the silk sheet material while fluidized drying.
Step e: the dried silk sheet material is conveyed to a spiral feeding and discharging device 8, is adsorbed into a spiral channel through negative pressure, and is combined, arranged and gathered into a cylindrical material under the action of negative pressure air flow.

Preferably, the outer shell and the inner sleeve are connected by screw threads, in particular, the inner wall surface of the outer shell is connected with the outer wall surface of the inner sleeve by screw threads, i.e. the inner sleeve 32 can be detached from the outer shell 31, so that the cleaning guide piece 321 is convenient to detach to keep the guide piece clean. The diameter of the shell 31 gradually decreases from the feeding end 311 to the discharging end 312, and the shell takes a funnel shape. The housing 31 has a high pressure air inlet 313 at an outer surface near the feed end 311 so that a negative pressure suction force is generated at the feed end 311 for sucking the silk sheet material and a positive pressure pushing force is generated at the discharge end 312 for discharging the silk sheet material. Preferably, the number of the high-pressure air inlets 313 may be 2, and the high-pressure air inlets are symmetrically disposed on the outer surface of the feeding end 311. Arrows in fig. 7 indicate the direction of the air flow.

Preferably, the height of the guiding piece 321 is gradually changed from high to low, the height of the guiding piece 321 at the feeding end is 5-10 mm, and the height of the guiding piece 321 at the discharging end is 0-3 mm. Preferably, the thickness of the guide piece 321 is 0.2 to 1.2mm.

In each preferred embodiment, as shown in fig. 11, the spiral feeding and discharging device of the present invention further has a wire capturing net 33, where the wire capturing net 33 is disposed on the air flow guiding portion 320, so as to prevent the wire sheet material from directly contacting the plurality of guiding pieces 321, avoid the wire sheet material from being damaged under the action of the air flow, and simultaneously utilize the transverse air flow generated by the air flow on the guiding pieces, so that the material can smoothly travel along the spiral feeding and discharging device in the discharging direction, and prevent the accumulation of the wire sheet material. Preferably, the material of the screen 33 is a metal mesh, preferably a stainless steel mesh. The diameter of the mesh 331 of the catching net 33 is 0.4-1.5 mm.

Preferably, the cylindrical material formed in step e has a structure in which a plurality of the silk sheet materials are arranged along the axial direction of the cylindrical material and are interlaced with each other. The negative pressure air flow in the spiral feeding and discharging device 8 generates spiral air flow through the action of the air flow guide sheet 382 on the inner sleeve 381, namely spiral air flow similar to a tornado, and the spiral force intensity can be adjusted by adjusting the air flow speed, so that the material interweaving degree is adjusted, the larger the air flow speed is, the stronger the spiral force is, and the material interweaving degree is further higher.
Step f: the cylindrical material is fed to a forming device 9, which is wrapped with forming paper into a rod of filamentary material. The shaping device may be, for example, a shaping smoke gun.
Step g: the rod of filamentary material is slit into fixed length rods of filamentary material 40 by the slitting blade 10. The wire sheet material rod 40 has a structure shown in fig. 12, and includes a wrapping layer 41 for molding and a wire sheet material 42 inside the wrapping layer 41. The shredded web material rods 40 may be further processed for use in making products such as heated cigarettes.
In a preferred embodiment of the invention, 100 parts of tobacco leaves are pulverized (with the mesh number of 60-200 meshes), 100 parts of natural plants are pulverized (with the mesh number of 60-200 meshes), 50 parts of CMC aqueous solution (CMC concentration of 4%), 40 parts of glycerin are mixed and stirred uniformly to prepare a sheet material (with the thickness of 2cm and the width of 10 cm), the sheet material is sliced by a rotary blade device in a rotary manner to obtain a sheet material with the width of 1.5mm and the length of 1.5cm and the thickness of 1mm, the sheet material is fluidized and dried to obtain a sheet material with the moisture of 5%, the sheet material enters a spiral feeding and discharging device, the sheet material is folded by air flow into a forming device, and is wrapped by forming paper and cut into a 120mm sheet material rod, and the sheet material rod has the characteristic fragrance of tobacco and natural plants, and the vinegar fiber filter rod can be applied to conventional cigarettes.
As described above, the preparation method of the shredded sheet material can be used for preparing shredded sheet material rods by one-step molding of the natural plant powder material application functional material which is difficult to granulate, so that the shredded sheet material rods can be conveniently used for preparing heating cigarette smoke segments, and the problems of unstable product quality, flavor loss and the like caused by a plurality of process links can be avoided. The method can save equipment, the raw materials and the finished bar are molded on one set of equipment, and the liquid phase material and the solid phase material are prepared into the silk slice material bar at one time by the method. The silk slice material rod prepared by the method has certain elasticity and pores, stable absorption resistance and can be used for preparing a composite filter rod. For example, the method can cut the slice materials such as Chinese herbal medicines into slice materials to be made into filter sticks, and then the filter sticks and the acetate fiber filter sticks are compounded to prepare the Chinese herbal medicine slice compound filter sticks which are applied to cigarettes.
It will be apparent to those skilled in the art that the above embodiments are provided for illustration only and not for limitation of the invention, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the invention as long as they fall within the true spirit of the invention.
