[0029] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0030] This utility model provides a tobacco sieve plate 1, as shown in the attached figure. Figure 1 As shown, the tobacco sieve plate 1 includes a plate body 11, a sieve section 12 with mesh holes is provided on the plate body 11, and a blocking member 13 protruding from the working surface of the plate body 11 is fixedly provided on the plate body 11, the blocking member 13 being located in the sieve section 12.
[0031] The tobacco shreds to be screened are placed on the working surface of plate 11. By tilting or vibrating plate 11, the tobacco shreds move within screening zone 12. The mesh openings in screening zone 12 screen the tobacco shreds. Tobacco shreds with a diameter smaller than the mesh openings pass through the mesh and are separated to the other side of the working surface of plate 11, while tobacco shreds with a diameter larger than the mesh openings continue to move and be screened on the working surface of plate 11. Generally, fish-scale mesh openings are used in screening zone 12 to allow tobacco shreds with a diameter smaller than the mesh openings to be quickly discharged from the mesh.
[0032] The blocking element 13 is used to prolong the residence time of tobacco material on the screening section 12, that is, to slow down the movement speed of tobacco material on the plate 11, prolong the screening time of tobacco material, and thus improve the screening effect of tobacco material.
[0033] As attached Figure 1 As shown, the plate 11 has a screening section 12 and a carrying area 18 outside the screening section 12. During use, the tobacco material is poured onto the carrying area 18 of the plate 11. The carrying area 18 has no mesh to prevent the tobacco material from contacting the screening section 12 and causing wear on the mesh, thus affecting the screening effect. The tobacco material moves towards the screening section 12 under gravity or vibration. The blocking element 13 is located in the middle of the screening section 12 to slow down the movement speed of the tobacco material during its movement, thereby extending the screening time and improving the screening effect.
[0034] For example, see appendix. Figure 2 As shown, the blocking member 13 is set at the boundary between the screening section 12 and the carrying section 18 to slow down the movement speed of the tobacco material before it reaches the screening section 12. This can also extend the screening time of the tobacco material and improve the screening effect of the tobacco material.
[0035] In some embodiments, a plurality of blocking members 13 are provided and distributed along a linear path. In use, by tilting or vibrating the plate 11, the tobacco material moves along the linearly distributed path of the blocking members 13 on the plate 11. This multiple blocking members 13 repeatedly obstruct the movement of the tobacco material, further enhancing the effect of slowing down its movement, extending the screening time, and further improving the screening effect. (See attached diagram.) Figure 3 As shown, in this embodiment, the plate 11 is rectangular, the linear path is a straight line, and ten blocking elements 13 are distributed along the straight path. In other embodiments, the linear path may also be a planar curved path, combined with the attached... Figure 4 As shown (screening section 12 not shown), plate 11 is an arc-shaped plate, and the planar curve path is consistent with the arc shape of the arc plate.
[0036] It is important to note that when the path lengths of the straight path and the planar curved path are the same, the planar curved path plate 11 has a lower space occupancy rate, while the straight path plate 11 is easier to manufacture. Furthermore, tobacco material is more prone to falling off the planar curved path plate 11 when moving, affecting the screening effect. Therefore, the planar curved path plate 11 needs to be used in conjunction with side guards to prevent tobacco material from falling off during movement.
[0037] In some embodiments, the blocking member 13 is strip-shaped, and the length direction of the blocking member 13 intersects the extension direction of the linear path. (See attached diagram) Figure 3 and attached Figure 4 The strip-shaped blocking element 13 can make the tobacco material come into contact with the blocking element 13 as much as possible during the movement process and slow down the movement speed, thereby extending the screening time of the tobacco material and further improving the screening effect of the tobacco material.
[0038] Combined with appendix Figure 5 As shown, when the length direction of the blocking member 13 is perpendicular to the extension direction of the linear path, the blocking member 13 can cover the width of the screening section 12 with the shortest distance, so that the blocking member 13 can block and slow down all the tobacco material moving on the working surface of the plate 11. That is, the length of the blocking member 13 is equal to the width of the screening section 12.
[0039] Combined with appendix Figure 6As shown, when the length direction of the blocking member 13 intersects but is not perpendicular to the extension direction of the linear path, in order for the blocking member 13 to completely block and decelerate the tobacco material moving on the working surface of the plate 11, the length of the blocking member 13 needs to be greater than the width of the screening section 12. With this design, the blocking member 13 can also guide the movement direction and distribution of the tobacco material on the working surface of the plate 11, and control the distribution state of the tobacco material on the screening section 12.
[0040] In some embodiments, along the direction perpendicular to the working surface of the plate 11, the blocking members 13 are inclined in the direction of extension of the linear path, and all the blocking members 13 are inclined in the same direction. The function of the blocking members 13 is to slow down the movement speed of the tobacco material on the screening section 12, rather than to completely block the tobacco material. By uniformly tilting all the blocking members 13 and making the tilting direction face the direction of extension of the linear path, when the tobacco material moves on the screening section 12, it slows down after contacting the blocking member 13 and can pass over the blocking member 13 to continue moving, avoiding the tobacco material being completely stuck at the blocking member 13. In this embodiment, in conjunction with the attached... Figure 7 As shown, the blocking member 13 has an integrally formed connecting part 14 and a blocking part 15. The connecting part 14 is fixedly connected to the plate 11, and the blocking part 15 is inclined in the direction of extension of the linear path. The greater the inclination of the blocking part 15, the smaller the blocking effect on the tobacco material. The blocking member 13 with different inclinations of the blocking part 15 can be replaced as needed.
[0041] In some embodiments, the blocking member 13 is detachably connected to the plate 11. (See attached diagram) Figure 7 As shown, the connecting part 14 and the plate 11 are detachably connected by fastener 17, which also facilitates the replacement and maintenance of the blocking part 13.
[0042] This utility model also provides a tobacco shredding trough, including a trough body 2 and a tobacco shredding sieve plate 1 as described in any of the above embodiments. The plate body 11 is installed inside the trough body 2 with its working surface facing outward from the trough body 2. There is a gap between the plate body 11 and the bottom of the trough body 2, so that a space for accommodating the shredded tobacco material is formed between the plate body 11 and the trough body 2.
[0043] Appendix Figure 8 and attached Figure 9 As shown, after the plate 11 is connected to the trough 2, the working surface of the plate 11 faces upward. The tobacco material is placed on the working surface of the plate 11 for screening. The tobacco material that passes through the mesh falls into the bottom of the trough 2 for recycling, while the remaining tobacco material moves along the plate 11 through the entire screening section 12 before being collected. The trough 2 is designed to facilitate the installation of the plate 11 and to recycle the screened tobacco material. It also serves as a baffle to prevent the tobacco material from falling out from the side of the plate 11.
[0044] In some embodiments, the plate 11 and the groove 2 are detachably and fixedly connected. (See attached diagram) Figure 3 A connecting part 14 is integrally formed on the plate 11 to facilitate the fixing of the plate 11 and the trough 2. On the one hand, it is convenient to disassemble, replace and repair the plate 11, and on the other hand, it is convenient to adjust the tilt of the plate 11 in the trough 2. The greater the safe tilt of the plate 11 in the trough 2, the greater the movement speed of the tobacco material on the plate 11.
[0045] This utility model also provides a tobacco shredding sieving vibrating trough device, including a vibrator (not shown) and the tobacco shredding trough in any of the above embodiments. The vibrator is used to drive the trough 2 to vibrate, so that the tobacco material on the working surface of the plate 11 can move along the linear path distribution direction of the blocking member 13. It should be noted that the inclined setting of the plate 11 in the trough 2 and the setting of the vibrator are both for the purpose of moving the tobacco material on the plate 11. In specific use, one of the setting methods or a combination of the two setting methods can be selected according to the requirements.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0047] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
