Referring to fig. 1, a raw material screening device for tobacco processing comprises a screening box 1, wherein a screening mechanism 2 and a material containing mechanism 3 are arranged in an inner cavity of the screening box 1, the screening mechanism 2 comprises a vibrating plate 23 fixed at the bottom of the screening box 1 through a spring, a vibrating motor 24 fixed at the bottom of the vibrating plate 23, a screening plate I21 and a screening plate II 22 which are sequentially arranged on the vibrating plate 23 in an inclined manner from top to bottom, the mesh aperture of the screening plate I21 is larger than that of the screening plate II 22, and the material containing mechanism 3 comprises a sheet tobacco collecting box 31 communicated with the lower end of the screening plate I21, a pedunculate tobacco collecting box 32 communicated with the lower end of the screening plate II 22 and a powder collecting box 33 arranged at the bottom of the vibrating plate 23.

In a specific working process, because the aperture of the first screening plate 21 is larger than that of the second screening plate 22, the first screening plate 21 screens out small tobacco, tobacco stems, tobacco powder and the like to the second screening plate 22, and only large tobacco is reserved in the sheet tobacco collecting box 31 after the first screening plate 21 passes through the screening; the second screening plate 22 screens out the tobacco powder residue, tiny particles and the like, so that only the tiny tobacco leaves and the tobacco stems are left to enter the peduncle-shaped tobacco collecting box 32, then the tobacco powder, other tiny particle impurities and the like enter the powder collecting box 33, and finally three kinds of tobacco with different sizes can be separated through screening.

The screening mechanism 2 further comprises two mounting plates 25 fixed on two sides of the vibrating plate 23, a limiting piece 5 is arranged on one side, opposite to the two mounting plates 25, of the screening plate I21 and the screening plate II 22, and the screening plate I21 and the screening plate II 22 are detachably arranged between the two mounting plates 25 through the limiting piece 5.

In the above embodiment, as shown in fig. 2, preferably, the limiting member 5 includes a fixing block 51 fixed on one side of the two mounting plates 25, and cylindrical ribs 52 disposed on two side surfaces of the first screening plate 21 and the second screening plate 22, the fixing block 51 is provided with a clamping groove 53 matching with the cylindrical ribs 52 in shape, and the first screening plate 21 and the second screening plate 22 are detachably disposed between the two mounting plates 25 through the cooperation of the cylindrical ribs 52 and the clamping grooves 53. Specifically, because the first screening plate 21 and the second screening plate 22 are detachably disposed between the mounting plates 25, the first screening plate 21 and the second screening plate 22 can be replaced at any time, or when the first screening plate 21 and the second screening plate 22 are blocked, the first screening plate 21 and the second screening plate 22 can be removed for replacement or cleaning, so that smooth work is ensured. Wherein, the convex edges on the two side surfaces of the first screening plate 21 and the second screening plate 22 adopt the cylindrical convex edges 52, because when the vibration motor 24 drives the screening mechanism 2 to vibrate, the cylindrical convex edges 52 are clamped in the clamping grooves 53 matched with the cylindrical convex edges, so that the screening plates are not easy to fall off during vibration.

In the above embodiment, as shown in fig. 3 and fig. 4, preferably, the first screening plate 21 is composed of a plurality of first toothed plates 221, second toothed plates 222 and a bracket 223, the first toothed plates 221 and the second toothed plates 222 are alternately staggered to form the screen holes 6, the bracket 223 is provided with a plurality of movable slots 7 for placing the ends of the first toothed plates 221 and the second toothed plates 222, and the two ends of the first toothed plates 221 and the second toothed plates 222 pass through the movable slots 7 and are in threaded connection with the fastening nuts. Specifically, the two ends of the first toothed plate 221 and the second toothed plate 222 pass through the movable slot 7 and can move left and right in the movable slot 7, and when the ends of the first toothed plate 221 and the second toothed plate 222 are moved left and right, the aperture size of the sieve mesh 6 can be adjusted, because the tobacco size is sometimes required to be different according to the actual situation, in order to avoid frequent replacement of the sieving machine or the sieving plate, the aperture size of the sieve mesh 6 of the first sieving plate 21 can be adjusted to meet the requirement, and the cost is reduced. After the mesh 6 is adjusted to a predetermined size, the first rack plate 221 and the second rack plate 222 are fixed by fastening nuts (not shown) to prevent the mesh from sliding left and right in the movable slot 7.

In the above embodiment, preferably, the inner surface of the movable slot 7 is provided with saw-tooth strips 71, and the friction between the ends of the first toothed plate 221 and the second toothed plate 222 and the movable slot 7 is increased by the saw-tooth strips 71.

In the above embodiment, as shown in fig. 5, it is preferable that the second screening plate 22 is a stainless steel ring net, because the first screening plate 21 mainly retains only large tobacco leaves, so that the aperture of the mesh 6 of the first screening plate 21 is larger than that of the mesh 6 of the second screening plate 22, and the second screening plate 22 mainly retains tobacco stems and small tobacco leaves, and the powder is removed by screening, so that the aperture of the mesh 6 of the second screening plate 22 is not required to be too large, and the aperture size of the mesh 6 does not need to be adjusted, so that a common stainless steel ring net with smaller aperture is adopted.

In the above embodiment, it is preferable that the lower ends of the first screening plate 21 and the second screening plate 22 are respectively connected with the first discharge port 8 and the second discharge port 9 disposed on the mounting plate 25.

In the above embodiment, preferably, a baffle 10 is disposed between the sheet tobacco collecting box 31 and the stem tobacco collecting box 32, and one end of the baffle 10 extends to the bottom of the first outlet 8. Specifically, in order to avoid mixing of the screened tobacco leaves after exiting from the first outlet 8 and the second outlet 9, a baffle 10 is provided between the sheet tobacco collecting box 31 and the stem tobacco collecting box 32, so that the large tobacco leaves enter the sheet tobacco collecting box 31 only through the first outlet 8, and the tobacco stems and small tobacco leaves enter the stem tobacco collecting box 32 only through the second outlet 9.

The vibration plate 23 is provided with a plurality of through holes 11 for sieving powder. The through holes 11 facilitate the entry of tobacco powder into the powder collection box 33, avoiding long-term accumulation of powder inside the screening box 1 or into other collection boxes.

In the above embodiment, preferably, the top of the inner cavity of the screening box 1 is provided with the dust collector 12, one end of the dust collector 12 is connected with the dust collection box 14 arranged outside the screening box 1 through the dust collection pipeline 13, and the upper part of the dust collector 12 is also covered with the filter screen 15. Specifically, because the existing screening of the tobacco lacks a smoke treatment device, dust scattering phenomenon is easy to occur during screening, and the health of staff is endangered, so the dust collector 12 is arranged at the top of the inner cavity of the screening box 1 to suck most of dust generated by vibration screening.

Referring to fig. 6, the front of the screening box 1 is further provided with a box door 16, and the top of the screening box 1 is provided with a feeding port 4. When screening plate one 21 or screening plate two 22 is blocked, replacement or repair can be performed by opening the door 16.

The foregoing examples merely illustrate specific embodiments of the utility model, which are described in greater detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
