Description

Anti-clogging screening device for tea processing

Technical Field

The utility model relates to the technical field of screening devices, in particular to an anti-clogging screening device for tea processing.

Background Art

Before tea leaves the factory, they must meet certain grade standards in appearance. They need to be screened before entering the pile fermentation and steaming processes, and tea leaves with large differences in diameter and length need to be distinguished, and finally clean tea of various grades is obtained. At present, tea production factories generally use screening equipment such as shaking screens, circular screens, air separators and stem pickers for screening of tea leaves. These screening equipments are all screened separately, that is, the tea sorted from the outlet of the front-end equipment needs to be loaded with a storage device and then sent to the entrance of the next equipment for a second screening. After screening by different types of screening machines, different types of tea strips such as length, thickness, etc. in the raw tea are separated, and then sorted into various screen number teas with almost consistent size and thickness and meeting certain specifications.

The Chinese patent with publication number CN219519561U discloses a sieving device for tea processing that prevents clogging. The patent includes a mounting shell, a mounting bracket is fixedly connected to the bottom of the mounting shell, mounting grooves are provided on both sides of the outer wall of the mounting shell, a mounting slider is slidably connected inside the mounting groove, a mounting support plate is fixedly connected to the side wall of the mounting slider, a mounting screw is rotatably connected between the two sides of the inner wall of the mounting groove, and one end of the mounting screw passes through the mounting shell and is fixedly connected to the mounting worm gear. The patent drives the special-shaped disk to rotate by driving the motor, so that a driving force is given to the push rod, which facilitates the push rod to drive multiple anti-blocking plugs on the push plate to pass through the sieve holes on the first sieve or the second sieve, thereby reducing the clogging of the sieve holes by materials, so that there is no need to stop the machine for manual cleaning, and the tea can be continuously adjusted and screened to improve the use effect.

Based on the above search and combined with the prior art, we found that:

The existing device cleans the sieve holes by pushing multiple anti-blocking rods on the plate through the sieve holes on the first sieve or the second sieve. However, repeatedly using the rods to insert the sieve holes for cleaning will cause excessive squeezing and damage to the sieve parts. During the continued screening process, the sieve will be damaged and its strength will deteriorate, thereby affecting the screening operation of the tea leaves.
