Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, and particularly relates to a tea hair screening device. Background Art

[0002] The processing of fresh leaves into rough tea only completes the primary processing and can only be regarded as a semi-finished product. Generally, this kind of tea will not be sold on the market. Only the finished tea after fine processing will be sold on the market. Rough tea only completes the preliminary production of tea, and is generally rough, with overlapping grades and confused qualities. It often contains impurities such as inclusions, hair, broom hair, and tea fluff. To turn rough tea into a commodity for sale, fine processing becomes essential. The main purpose of tea fine processing is to tidy up the appearance, remove the rough and inferior parts, improve the internal quality, distinguish the grades, reconcile the quality, and make the tea reach the pure quality characteristics; an essential step in tea fine processing is to remove impurities such as hair and tea fluff from the tea.

[0003] Currently, the utility model with the publication number CN209582738U discloses a device for removing tea dander, including a frame, a driven roller, a conveyor belt, a driving roller, and a conveyor belt motor. The driven roller and the driving roller are rotatably supported on the frame; the conveyor belt is sleeved on the driven roller and the driving roller to form a belt transmission mechanism; the conveyor belt motor is fixedly connected to the driving roller. Among them, it further includes an electrostatic roller motor, an electrostatic roller, a brush roller motor, and a brush roller. The electrostatic roller is rotatably supported on the frame and fixedly connected to the electrostatic roller motor; the brush roller is rotatably supported on the frame and fixedly connected to the brush roller motor; the electrostatic roller and the brush roller are in contact with the conveyor belt.

[0004] In the above solution, the device for removing tea dander in the prior art generally uses a roller for electrostatic adsorption.

The transmission assembly is started to drive the plurality of felt rollers 4 to rotate in the same direction, so that the hair in the tea is wound around the felt rollers 4. At the same time, impurities such as small stones in the tea can fall through the gaps between two adjacent felt rollers 4 and are discharged through the output channel, so as to effectively screen out the hair and small stones and other impurities in the tea. Then, the tea after screening is conveyed to the vibration conveying mechanism, and the tea can be conveyed into the screening machine 2 through the vibration conveying mechanism for further screening.

[0037] By providing multiple felt rollers 4, the hair in the tea leaves can be effectively screened out, solving the problem that in the prior art, the tea leaves need to be repeatedly adsorbed to completely remove the hair, thereby improving the efficiency of screening out the hair in the tea leaves.

[0052] Working principle:

[0053] When it is necessary to screen out the hair in the tea leaves, after the tea leaves are output from the output end of the lifting conveyor 1, they fall on the outer wall of the air outlet pipe 6, and under the guidance of the air outlet pipe 6, the tea leaves slide onto the felt roller 4. The first blower 5 is started, so that when the tea leaves slide onto the felt roller 4, the tea leaves are dispersed, so that the dispersed tea leaves slide onto the felt roller 4. The motor 12 is started to drive one of the belt pulleys 10 to rotate, so that under the action of the belt 11, a plurality of belt pulleys 10 are driven to rotate, so that a plurality of felt rollers 4 can be driven to rotate in the same direction, so that the hair in the tea leaves is wound around the felt roller 4. At the same time, fine stones and other impurities in the tea leaves can fall into the transverse channel 13 through the gap between two adjacent felt rollers 4, and move through the transverse channel 13 into the inclined channel 14, so that the impurities can be discharged through the inclined channel 14. Then the tea leaves after screening are conveyed onto the conveying plate 7, and the vibrator 9 is started to drive the conveying plate 7 to vibrate, so that the tea leaves on the conveying plate 7 can be vibrated and conveyed into the screening machine 2 for secondary screening. At the same time, a plurality of second blowers 15 are started, so that the air flow blows out from the air outlet holes 701, thereby the tea leaves can be dispersed.
