Technical Field

[0001] The utility model relates to the technical field of tobacco equipment, in particular to a shredded stem separation device. Background Art

[0002] The tobacco stem content needs to be controlled during the cigarette production process to ensure the quality of the finished cigarette products. In the tobacco factory, the different physical properties of tobacco and tobacco stem densities are used to set up airflow to drive the tobacco material to move, so that the tobacco flow hits the separation plate at high speed. Under the action of density, baffle and airflow, the tobacco and stem fall down in sequence to achieve separation.

[0003] In the prior art, the separation plate is a rectangular iron plate. However, due to the irregular shape of tobacco stems, tobacco stems are easily attached to the top of the separation plate during the separation process, commonly known as "hanging tobacco". Some of the tobacco stems attached to the top of the separation plate cannot be successfully recovered. With the continuous collision of subsequent tobacco streams, the tobacco stems may be mixed into the tobacco, affecting the separation effect of tobacco stems and tobacco, and thus affecting the quality of cigarettes.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0024] See also Figures 1 to 5 A shredded tobacco stem separation device includes a separation plate 10 and a mounting base 20 for fixing the separation plate 10. The separation plate 10 is horizontally placed on the moving path of the shredded tobacco flow, and separates the tobacco stems and shredded tobacco by using the difference in weight. The separation plate 10 is vertically arranged, and an exhaust port 111 is arranged on the top thereof. A plurality of exhaust ports 111 are arranged along the length direction of the separation plate 10. The exhaust ports 111 are connected to an air source through an air pipe 112. The exhaust ports 111 are arranged upward so that the airflow is blown out above the separation plate 10 through the exhaust ports 111.

[0025] The separation plate 10 is a flat plate, which is placed horizontally on the moving path of the tobacco flow and is arranged vertically. Its large surface is perpendicular to the moving direction of the tobacco flow to stop the tobacco flow. Due to the effect of inertia, the heavier tobacco stems pass over the separation plate 10, and the lighter tobacco is stopped by the separation plate 10, so as to separate the tobacco stems from the tobacco. Along the length direction of the separation plate 10, a ventilation duct 11 is arranged on the top of the separation plate 10, and the exhaust port 111 is arranged at intervals along the ventilation duct 11, and the exhaust port 111 is arranged upward, one end of the ventilation duct 11 is closed, and the other end thereof is connected to the air source. The airflow flows in the ventilation duct 11 and is discharged upward through the exhaust port 111, blowing off the tobacco stems that are not completely separated and hooked on the top of the separation plate 10 and the ventilation duct 11, so as to separate the tobacco stems from the tobacco.

[0026] In order to prevent the airflow blown out of the exhaust port 111 from hindering the tobacco stems from passing over the separation plate 10 and reducing the separation effect of the separation plate 10 , in the present application, air is blown through the gap of the exhaust port 111 .

[0027] Furthermore, a guide plate 12 is provided at the bottom of the separation plate 10, the guide plate 12 is connected to the separation plate 10, the guide plate 12 is tilted, and the bottom of the guide plate 12 is tilted in the opposite direction of the movement of the tobacco flow. When the tobacco flow stops blowing, the tobacco stopped by the separation plate 10 falls along the separation plate 10 and the guide plate 12 in sequence, and the tilted guide plate 12 gradually guides the tobacco to the side away from the separation plate 10, so that the tobacco is separated from the tobacco stems that pass over the separation plate 10.

[0028] A baffle 13 is also provided behind the separation plate 10. The top of the baffle 13 is inclined near the separation plate 10, and the top of the baffle 13 is higher than the top of the exhaust port 111, and the bottom of the baffle 13 is not higher than the separation plate 10, so as to stop the tobacco stems that pass through the separation plate 10 and the tobacco stems that are blown up by the blowing port. An extension plate is provided at the lower end of the baffle 13, and the extension plate is connected to the baffle 13. The extension plate is vertically arranged to collect the tobacco stems uniformly to prevent the tobacco stems from continuing to move and scatter after passing through the separation plate 10. The length of the baffle 13 is consistent with the length of the separation plate 10, and can cover the tobacco stems that pass through the separation plate 10 to avoid omission.

[0029] Mounting seats 20 are provided at both ends of the separation plate 10, and the mounting seats 20 are fixed on the frame. Mounting slots 20 are provided on the mounting seats 20, and fixing blocks 21 are provided in the mounting slots 202. The fixing blocks 21 are fixedly connected to the separation plate 10, and the mounting slots 202 are arranged in a vertical direction. The mounting slots 202 pass through the bottom of the mounting seats 20 to facilitate the installation of the fixing blocks 21. The inner side wall of the installation has a right-angle edge. Relatively speaking, the outer periphery of the fixing blocks 21 has a right-angle edge to limit the rotation of the fixing blocks 21 in the mounting slots 202. Adjustment holes 201 are provided on the mounting seats 20, and the adjustment holes 201 are vertically arranged to pass through the mounting seats 20 and the fixing blocks 21. An adjustment screw 203 is provided in the adjustment hole 201. The mounting seats 20 and the fixing blocks 21 are connected through the adjustment screw 203. The fixing blocks 21 are moved up and down along the mounting slots 202 by rotating the adjustment screw 203, and the fixing blocks 21 drive the separation plate 10 to move up and down, thereby changing the separation effect of the separation plate 10. For example, the higher the separation plate 10 is positioned, the fewer tobacco stems can be removed; the lower the separation plate 10 is positioned, the more tobacco stems can be removed. The separation effect of the separation plate 10 can be changed by adjusting the height of the separation plate 10 to meet the physical index requirements of cigarettes of different specifications.

[0030] In this embodiment, the top of the mounting seat 20 has an inclined surface 204 , and the upper end of the baffle 13 is fixed to the inclined surface 204 by screws.

[0031] The separation plate 10 is connected to the fixed block 21 through an angle code 22. The angle code 22 includes a vertically connected fixing surface 221 and a mounting surface 222. The fixing surface 221 is fixedly connected to the separation plate 10, and the mounting surface 222 is fixedly connected to the fixed block 21. The edges connecting the mounting surface 222 and the fixing surface 221 correspond to the right-angled edges on the periphery of the fixed block 21. The angle code 22 and the fixed block 21 are mutually limited to improve the stability of the connection between the separation plate 10 and the fixed block 21.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
