Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a screening device for tea processing. Background Technology

[0002] Tea is a beverage made from the tender leaves of the tea plant. It can be processed and manufactured using various techniques to produce different types of tea, such as green tea, black tea, dark tea, white tea, yellow tea, and oolong tea. Originating in China, tea is an important part of traditional Chinese culture, possessing rich historical and cultural connotations. During processing, tea leaves are sometimes made into tea cakes to save storage space, facilitate transportation and preservation, enhance flavor, and increase collectible value.

[0003] After tea leaves are processed into tea cakes, they need to be sorted and screened according to their shape and color quality. Currently, tea cake sorting is generally done manually. Manual sorting is subject to subjective factors and cannot achieve precise sorting of tea cakes, thus reducing the sorting effect. Therefore, we propose a sorting device for tea processing to solve the above problems. Utility Model Content

[0025] The sorting component workbench 4 includes a placement platform 41. Two grip handles 42 are connected to the outer surface of the placement platform 41, and two adjusting screws 43 are connected to the bottom surface of the placement platform 41. Each adjusting screw 43 has a support cylinder 44 fitted on its outer surface, and an adjusting nut 45 is threaded onto its outer surface. An arc-shaped support rod 46 is connected to the right side of each support cylinder 44, and the right end of each arc-shaped support rod 46 is fixedly connected to the left side of the mounting leg 5. This allows for height adjustment of the placement platform 41, facilitating the storage and placement of tea cakes. The left side of the intelligent sorting box 2 is hinged to a maintenance door 18 via two hinges.

[0027] The working principle of this utility model is as follows:

[0028] In use, the tea cakes to be sorted are first placed on the placement platform 41. The adjusting nut 45 is loosened to loosen the adjusting screw 43 according to the feeding requirements, and the height of the placement platform 41 is adjusted. Then, the drive motor 17 is controlled to work to control the sorting conveyor 1. The tea cakes are sequentially placed on the upper part of the sorting conveyor 1 for conveying. The tea cakes are moved to the lower part of the intelligent sorting box 2. The integrated machine vision image acquisition device 12 is used to acquire images of the conveyed tea cakes and transmit the acquired data to the PLC editing controller 3. The PLC controller 3 performs intelligent analysis on the characteristics of the tea cakes, such as color, quality, shape and type, and automatically matches the grade code. At the same time, the electric telescopic rod 16 is controlled to drive the material sorting plate 6 to open and close. The first-level tea cakes fall into the front collection box 8, and the second-level tea cakes fall into the rear collection box 8 through the unloading ramp 7. This realizes the intelligent mechanical sorting operation of tea cakes, achieving fast, effective and accurate sorting of tea cakes.
