Screening device in tea packaging process and screening method thereof

Abstract

The invention discloses a screening device in tea packaging process. The screening device comprises a feeding frame, a screening frame and a discharging frame. The screening frame is located between the feeding frame and the discharging frame, the feeding frame is provided with a first conveying belt, and the end, away from the screening frame, of the first conveying belt is connected with a second rotating wheel in a penetrating manner. The problems that when an existing tea screening device is used, the screening speed is low, efficiency is low, after screening, tea cannot be conveniently taken out of the interior of the screening device for packaging, the whole process needs to be manually and repeatedly cooperated with the device for operation, consequently, the whole packaging efficiency is greatly reduced, in the screening process, a series of cooperated manners of turnover, stirring and the like are adopted for tea screening, the tea is easily broken, due to the fact that in thescreening process, a screen net is quite easily blocked, the screening effect is easily and greatly reduced, even, screening cannot be carried out, the blocked screen net needs to be manually treated, and troublesome is caused can be solved.

Description

technical field [0001] The invention relates to the field of screening devices for tea packaging, in particular to a screening device and a screening method in the tea packaging process. Background technique [0002] During the packaging process of tea leaves, a sieving device is needed to sieve the tea leaves, so as to sieve tea leaves of different sizes. However, there are still certain defects in the existing devices of this type. The efficiency is low, and it is inconvenient to take out the tea leaves from the screening device for packaging after the screening is completed. In the whole process, it is necessary to manually cooperate with the device for many times to operate, which leads to a great reduction in the efficiency of the entire packaging. Secondly, in the screening In the process, a series of matching methods such as flipping and stirring are used to sieve the tea, which is easy to cause damage to the tea, and because the sieve is easily blocked during the sie...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a screening device and screening method in the tea packaging process, which can solve the problem of slow screening speed and low efficiency of the existing tea screening device during use, and the inconvenience of tea leaves after screening The tea leaves are taken out from the screening device for packaging. In the whole process, manual operations are required to cooperate with the device many times, which leads to a great reduction in the efficiency of the entire packaging. The way of sieving tea leaves is easy to cause damage to the tea leaves, and because the sieve mesh is easily blocked during the sieving process, the sieving effect is easily reduced, and even the sieving cannot be carried out, and manual cleaning is required. The clogged screen is dealt with, which is a troublesome problem
