A conveying net plate and transmission mechanism of a cigarette wind separator

Abstract

The application discloses a conveying net plate and a transmission mechanism of a cigarette air separator, which comprises a net plate, a side plate and a connecting plate. One side of the net plate is bent downward, and a plurality of mesh holes are formed in the net plate. The side plate is connected to the other side of the net plate. The connecting plate is arranged on the lower side of the net plate and is welded with the bent side of the net plate and the side plate. The middle part of the connecting plate is extruded and folded downward to form a transmission plate. The transmission plate is installed on a transmission chain with a lug and is engaged with a sprocket on a conveying shaft to drive the conveying net plate. The conveying net plate of the cigarette air separator is combined into an inverted trapezoidal structure by the side plate, the net plate and the connecting plate, so that the overall load bearing and stress of the net plate are greatly strengthened. The middle part of the connecting plate is extruded and folded to form a transmission plate, so that the overall strength of the transmission plate is increased. Circular holes are made on the front of the net plate according to the air inlet amount, and a flower basket ventilation opening is formed on the connecting plate, so that the air amount requirement is met.

Description

Technical Field

[0001] This invention relates to the field of cigarette equipment, and more specifically, to a conveyor mesh plate and transmission mechanism for a cigarette air separator. Background Technology

[0002] After the raw tobacco leaves and stems are separated by the leaf threshing machine, the tobacco leaves and stems need to be separated in the air separator. The air separator consists of a lower air inlet chamber, a conveyor mesh plate transmission mechanism, an air separation chamber, and a material discharge port.

[0003] The conveyor belt drive mechanism consists of a drive roller, a driven roller, a belt chain, a belt, and a frame.

[0004] In the existing technology, the air separation chamber is often blocked, requiring multiple people to enter and clear the blockage before production can be restored. The presence of multiple people in the air separation chamber can easily damage the conveyor screen. The conveyor screen is designed in a "7" shape and is assembled and used with pins. It has poor strength and plasticity, which can easily lead to the breakage of the conveyor screen. Summary of the Invention

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] according to Figures 1 to 3 As shown, the present invention provides a conveying mesh plate 20 for a cigarette air separator, including a mesh plate 1, a side plate 3, and a connecting plate 2.

[0033] One side of the mesh plate 1 is bent downwards, and multiple mesh holes 11 are provided on the mesh plate 1; the side plate 3 is connected to the other side of the mesh plate 1.

[0034] The connecting plate 2 is disposed 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 pressed and folded downward to form a transmission plate 21. The transmission plate 21 is mounted on a transmission chain with lugs and meshes with the sprocket and chain on the conveying shaft to drive the conveying mesh plate 20.

[0035] The conveying mesh plate 20 of the cigarette air separator disclosed in this invention is composed of side plate 3, mesh plate 1 and connecting plate 2 to form an inverted trapezoidal structure, which greatly enhances the overall load-bearing capacity and stress of mesh plate 1; the middle part of the connecting plate 2 is formed by compression and folding to form a transmission plate 21, which increases the overall strength of transmission plate 21; and round holes are made on the front of mesh plate 1 according to the air intake to meet the air volume requirements.

[0036] 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°.

[0037] In this embodiment, since the conveyor mesh plate 20 is not a planar structure at the position of the conveyor shaft, but a curved structure with the conveyor shaft as the center, the side plates 3 and the bent edges of the two adjacent sets of conveyor mesh plates 20 will approach each other. In order to ensure the stable conveying of the conveyor mesh plate 20, the included angle between the mesh plate 1 and the bent edge and side plate 3 should be reduced.

[0038] Furthermore, the top of the side plate 3 is provided with an extension plate 31 facing away from the mesh plate 1, and the side of the mesh plate 1 near the bend is provided with a downward step surface 12, and the extension plate 31 and the step surface 12 fit together.

[0039] In this embodiment, the extension plate 31 overlaps with the step surface 12, so that adjacent conveyor mesh plates 20 are located on the same horizontal line as much as possible, preventing the conveyor mesh plates 20 from being independent of each other and causing inconsistent heights.

[0040] Furthermore, multiple ventilation openings 22 are provided at the connection points between the connecting plate 2 and the bent edge of the mesh plate 1 and the side plate 3. Ventilation openings 22 are provided in the front circular hole of the mesh plate 1 and on both sides of the side plate 3 according to the air intake volume, thus meeting the air volume requirements.

[0041] Then according to Figure 4 As shown, the present invention also provides a transmission mechanism for a cigarette air separator, including a drive roller sprocket 30, a driven roller sprocket 40, a chain with lugs 10, and a conveyor mesh plate 20 as described in any of the above embodiments;

[0042] The two ends of the conveyor mesh plate 20 are sequentially connected to the chain with lugs 10 by bolts. The chain with lugs 10 is sleeved on the driving roller sprocket 30 and the driven roller sprocket 40. The transmission plate 21 of the conveyor mesh plate 20 meshes with the driving roller sprocket 30 and the driven roller sprocket 40.

[0043] Furthermore, the driven roller sprocket 40 is provided with tensioning mechanisms 50 at both ends to adjust the tension of the chain 10 with lugs.

[0044] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
