[0028] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0029] Such as Figures 1 to 4As shown in the figure, this embodiment provides a separating vibrating sieve for separating a mixture of tobacco leaf fragments and sundries. The separating vibrating sieve includes a screen panel 2, a vibration module, and a processing module; the screen panel 2 is a plate-like member, and one end of the screen panel 2 is bent upward and inward to form an arc-shaped elbow 9. The arc-shaped elbow 9 is a 180° arc. A first screen area 6 is provided at one end of the screen panel 2 away from the arc-shaped elbow 9. A number of first through holes are evenly distributed in the first screen area 6. A second screen area 8 is provided at one end of the screen panel 2 close to the arc-shaped elbow 9. A number of second through holes are evenly distributed in the second screen area 8. A third screen area 10 is provided on the arc-shaped elbow 9. A number of third through holes are evenly distributed in the third screen area 10. The aperture of the second through hole is larger than that of the first through hole, and the aperture of the third through hole is larger than that of the first through hole; the vibration module is used to drive the mixture placed on the screen panel 2 to move toward the arc-shaped elbow 9 along the length direction of the screen panel 2; the processing module includes a receiving component and a conveying air duct 4. The receiving component is used to collect the tobacco leaf fragments passing through the screen panel 2, and the conveying air duct 4 is used to convey the tobacco leaf fragments in the receiving component out of the processing module. Specifically, the mixture falls into the separating vibrating sieve from the feeder, and the feeder is located directly above the end of the screen panel 2 away from the arc-shaped elbow 9.

[0030] This separating vibrating sieve uses through holes of different sizes on the screen panel 2 and the arc-shaped elbow 9 to separate tobacco leaf fragments and sundries; the arc-shaped structure design of the arc-shaped elbow 9 can separate the sundries without dropping them; under the drive of the vibration module, during the relative movement of the mixture on the screen panel 2, it successively passes through the first screen area 6 and the second screen area 8 with different-sized mesh holes. The through holes of different sizes on the screen panel 2 enable the mixture such as tobacco leaf fragments and sundries to be effectively flattened during the vibration separation by the vibrating sieve, realizing the effective separation of each component in the mixture; the tobacco leaf fragments continuously fall through the first screen area 6 and the second screen area 8 with small-sized apertures and are aggregated at the receiving component below, and are sent to the next processing step by the conveying air duct 4; the sundries continuously move toward the arc-shaped elbow 9 with the vibration of the vibrating trough and are left above the third screen area 10 with large-sized arc-shaped apertures. The above improvements can efficiently separate tobacco leaf fragments and sundries without clogging. The operator only needs to regularly clean the sundries at the arc-shaped elbow 9. Thus, the efficiency of sundry sorting and material conveying is improved. The design of the vibration module enables the mixture to move smoothly along the length direction of the screen panel 2, improving the screening efficiency. The processing module facilitates the collection and conveyance of tobacco leaf fragments, contributing to the automated processing of the screening operation. This separating vibrating sieve has the advantages of simple design, simple operation improvement, and strong operability, and can separate tobacco leaf fragments and sundries, thereby improving the screening efficiency.

[0031] In this embodiment, a plurality of guide bars 7 are convexly provided at intervals on the upper plate surface of the screen panel 2, and the length direction of the guide bars 7 is the same as the length direction of the screen panel 2. Specifically, three guide bars 7 are provided on the screen panel 2.

[0032] The guide strip 7 can guide the mixture to move more evenly along the length direction of the screen panel 2, so that the tobacco leaf fragments can be diverted and spread on the screen panel 2 while the mixture is screened, thereby improving the uniformity and accuracy of the screening effect.

[0033] Furthermore, the projection of the guide bar 7 on the cross section is in the shape of a Chinese character "冂". By defining the specific structure of the guide bar 7, the guide bar 7 can disperse the mixture more effectively, thereby preventing the mixture from piling up on the screen panel 2, and further improving the screening efficiency.

[0034] In this embodiment, the storage assembly includes a vibration trough body 1 and two vibration trough body side panels 3, the screen panel 2 is placed in the vibration trough body 1, the vibration trough body side panels 3 are fixed to the trough wall of the vibration trough body 1, the vibration trough body side panels 3 are rectangular plate-shaped parts and extend along the length direction of the screen panel 2, and the top edge of the vibration trough body side panels 3 is higher than the top of the arc elbow 9. The structural design of the vibration trough body side panels 3 prevents the leakage of tobacco leaf fragments and improves the collection efficiency. Combined with the arrangement of the vibration trough body 1 and the two vibration trough body side panels 3, the storage assembly can effectively collect tobacco leaf fragments passing through the screen panel 2.

[0035] Furthermore, the storage assembly further includes a vibration trough panel 5, which is arranged directly below the screen panel 2 and the arc elbow 9, and is used to collect tobacco leaf fragments passing through the screen panel 2. The bottom of the vibration trough panel 5 is provided with a discharge port connected to the conveying air duct 4. The use of the vibration trough panel 5 to collect tobacco leaf fragments can ensure complete collection of tobacco leaf fragments and facilitate subsequent processing. The setting of the discharge port allows the tobacco leaf fragments on the vibration trough panel 5 to be discharged from the separation vibration screen by wind transport.

[0036] Specifically, the screen panel 2 is fixed in parallel to and just above the vibration trough panel 5 through the vibration trough body side plate 3, and is spaced apart from the vibration trough panel 5, thereby facilitating the transportation of the mixture.

[0037] In this embodiment, the width of the arc elbow 9 gradually increases in the direction close to the screen panel 2 along the length direction of the arc elbow 9 until it is the same as the width of the screen panel 2. The above design optimizes the structure of the arc elbow 9 and improves the ability of the arc elbow 9 to collect debris, thereby reducing the difficulty of operators to collect debris and helping to reduce the workload of operators.

[0038] Exemplarily, the aperture diameter of the second through-hole is equal to that of the third through-hole. The limitation that the aperture diameter of the second through-hole is equal to that of the third through-hole helps to make the separating vibrating sieve more flexible, so that the size of the through-hole aperture can be adjusted according to actual needs to adapt to tobacco leaf fragments and sundries of different sizes. Specifically, the aperture diameter of the first through-hole is 5 mm, the aperture diameter of the second through-hole is 10 mm, and the aperture diameter of the third through-hole is 10 mm.

[0039] In this embodiment, the first screen area 6 and the second screen area 8 are covered with the screen panel 2. The above limitation enables the screen panel 2 to be fully utilized, thereby improving the screening efficiency. At the same time, the above design also ensures that the mixture can be effectively screened in each area.

[0040] Furthermore, the screen panel 2 is a rectangular plate, the first screen area 6 is rectangular, and the second screen area 8 is rectangular. The above limitations make the structure of the separating vibrating sieve more regular, which is more convenient for manufacturing, installation and use. At the same time, the rectangular design also enables the mixture to be more evenly distributed during the screening process.

[0041] In this embodiment, the screen panel 2 and the arc-shaped elbow 9 are integrally processed and formed. With the above structural limitation, it is ensured that the arc-shaped elbow 9 is seamlessly connected to the upper plate surface of the screen panel 2. At the same time, the design of integrally processing and forming the screen panel 2 and the arc-shaped elbow 9 improves the structural stability and durability of the separating vibrating sieve, reducing the cost and time for maintaining the separating vibrating sieve. Moreover, the integrally formed design also makes the separating vibrating sieve more compact and lightweight, which is more convenient for transportation and use.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
