Description
Technical Field
[0001] The utility model relates to the technical field of tea processing, in particular to a sorting chamber structure for tea screening. Background Art
[0002] Tea refers to the leaves of the evergreen shrub tea tree that can be used to make tea. Tea contains catechins, cholestenone, caffeine, inositol, folic acid, pantothenic acid and other ingredients, which can improve human health. Tea needs to be processed deeply during the production process. The deep processing of tea refers to the use of fresh tea leaves, finished tea leaves as raw materials, or the use of tea leaves, tea factory waste and scraps as raw materials, using the corresponding processing technology and means to produce tea-containing products. After the tea is processed, it needs to be sorted by a sorting machine. The tea enters the machine from the top hopper. Through the vibration of the vibrator device, the selected material slides down the channel, accelerates to fall into the observation area in the sorting room, and passes through the sensor and the background plate. Under the action of the light source, according to the intensity and color change of the light, the system generates an output signal to drive the solenoid valve to blow out the different-colored tea leaves into the waste cavity of the receiving hopper, while the good tea leaves continue to fall into the finished product cavity of the receiving hopper, thereby achieving the purpose of sorting.
[0003] After the sorting machine is used, it needs to be maintained in time, and the brightness of the LED lamp should be observed to see if it is normal, and preparations for replacement should be made in time. However, since the LED lamp is installed inside the sorting chamber, the operator needs to disassemble the outer shell of the sorting chamber when replacing it, which increases the maintenance time. For this reason, we proposed a sorting chamber structure for tea screening that is convenient for replacing LED lamps. Utility Model Content
