AI Technical Summary
During the screening process, the tobacco wires are prone to block the holes of the screen, resulting in a decrease in screening efficiency. The screen needs to be cleaned. During the cleaning, the staff used a mesh brush to sweep the tobacco wires that blocked the screen out the holes of the screen. During this process, some of the unqualified tobacco wires are easily squeezed and passed through the screen, resulting in the screening tobacco wires containing larger tobacco wires.
An efficient tobacco vibrating screen is designed. By setting a backflash assembly on the surface of the guide rod inside the screen box, the mobile motor drives the moving screw to rotate, and drives the backflash assembly to move under the screen plate, blowing the tobacco that blocks the holes of the screen plate to prevent the blocked tobacco from falling through the holes.
It effectively prevents tobacco from clogging the screen, improves screening efficiency, prevents unqualified tobacco from being squeezed through the screen, and ensures the quality of the tobacco after screening.

Description
Technical Field
[0001] The utility model relates to the technical field of tobacco processing, and particularly relates to an efficient tobacco vibrating screen. Background Art
[0002] Tobacco is a plant widely planted and used worldwide. Its leaves can be chewed or made into cigarettes for smoking. Cigarettes are the most common tobacco products, made by cutting dried tobacco into shreds and wrapped in paper rolls for smoking. Although cigarettes are small in size, they contain various harmful substances, and long-term smoking is extremely harmful to health.
[0003] In the process of tobacco processing, it is necessary to screen tobacco shreds. The tobacco vibrating screen is a special equipment for screening tobacco materials such as tobacco shreds, tobacco flakes, and tobacco stems, and plays an important role in the tobacco processing industry. The tobacco vibrating screen is mainly divided into two types: linear vibrating screen and swing vibrating screen. The linear vibrating screen is suitable for large-scale continuous screening, while the swing vibrating screen is more suitable for fine screening. The tobacco vibrating screen is driven by an electric motor to drive an eccentric wheel or a crank to generate high-speed vibration, so that the tobacco materials on the screen are separated according to size.
[0004] However, during the screening process of tobacco shreds, since the tobacco shreds are easy to block the holes of the screen, the screening efficiency is reduced, and the screen needs to be cleaned. When cleaning, the staff uses a wire brush to sweep across the top of the screen to sweep out the tobacco shreds blocking the screen holes. In this process, some unqualified tobacco shreds are easily squeezed through the screen, resulting in larger tobacco shreds in the screened tobacco shreds. In view of this, this application proposes an efficient tobacco vibrating screen. Summary of the Utility Model
