[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] according to Figures 1 to 3 As shown, the utility model provides a conveying mesh plate 20 of a cigarette air selector, comprising a mesh plate 1, a side plate 3 and a connecting plate 2.

[0034] One side of the mesh plate 1 is bent downward, and a plurality of mesh holes 11 are formed on the mesh plate 1 ; the side plate 3 is connected to the other side of the mesh plate 1 .

[0035] The connecting plate 2 is arranged on the lower side of the mesh plate 1 and is welded to the bent edge of the mesh plate 1 and the side plate 3. The middle part of the connecting plate 2 is squeezed and folded downward to form a transmission plate 21. The transmission plate 21 is installed on a transmission chain with hanging ears and meshes with the sprocket and chain on the conveying shaft to drive the conveying mesh plate 20 to transmit.

[0036] The conveying mesh plate 20 of the cigarette air selector disclosed in the utility model is combined into an inverted trapezoidal structure by the side plates 3, the mesh plate 1 and the connecting plate 2, so that the overall load-bearing and force-bearing capacity of the mesh plate 1 is greatly enhanced; the middle part of the connecting plate 2 is formed into a transmission plate 21 by extrusion and folding, so that the overall strength of the transmission plate 21 is increased, and circular holes are manufactured on the front side of the mesh plate 1 according to the air intake volume to meet the air volume requirements.

[0037] Furthermore, the angle between the bent edge of the mesh plate 1 and the mesh plate 1 is 60° to 75°. The angle between the side plate 3 and the mesh plate 1 is 30° to 45°. And the sum of the angle between the bent edge of the mesh plate 1 and the mesh plate 1 and the angle between the side plate 3 and the mesh plate 1 is less than 90°.

[0038] In this embodiment, since the conveying mesh plate 20 is not a planar structure at the position of the conveying axis, but a curved structure with the conveying axis as the center, the side panels 3 and the bent edges of two adjacent groups of conveying mesh plates 20 will be close to each other. In order to ensure the stable transportation of the conveying mesh plate 20, the angle between the mesh plate 1 and the bent edge and the side panel 3 should be reduced.

[0039] Furthermore, an extension plate 31 is provided at the top of the side plate 3 in a direction away from the mesh plate 1 , and a downward step surface 12 is provided on one side of the mesh plate 1 close to the bend, and the extension plate 31 and the step surface 12 are matched with each other.

[0040] In this embodiment, the extension plate 31 overlaps the step surface 12 so that the adjacent conveying mesh plates 20 are located on the same horizontal line as much as possible, thereby preventing the conveying mesh plates 20 from being independent of each other and causing height inconsistency.

[0041] Furthermore, the connection between the connection plate 2 and the bending edge of the mesh plate 1 and the side plate 3 is provided with a plurality of ventilation holes 22. According to the air intake volume, the ventilation holes 22 are opened in the front circular holes of the mesh plate 1 and on both sides of the side plate 3 to meet the air volume requirements.

[0042] According to Figure 4 As shown, the utility model also provides a transmission mechanism of a cigarette air selector, comprising an active roller sprocket 30, a driven roller sprocket 40, a chain with hanging ears 10 and a conveying mesh plate 20 as described in any one of the above embodiments;

[0043] Both ends of the conveying mesh plate 20 are connected to the chain with hanging ears 10 in sequence by bolts. The chain with hanging ears 10 is mounted on the active roller sprocket 30 and the driven roller sprocket 40. The transmission plate 21 of the conveying mesh plate 20 is meshed with the active roller sprocket 30 and the driven roller sprocket 40.

[0044] Furthermore, tensioning mechanisms 50 are provided at both ends of the driven roller sprocket 40 to adjust the tension of the chain with hanging ears 10 .
