Description

Technical Field

[0001] The utility model relates to the technical field of tea spreading machines, in particular to a tea spreading machine unit. Background Art

[0002] Tea is a traditional Chinese drink with a long history and rich cultural connotations. In the process of tea production and processing, it needs to be spread out, which requires the use of a tea spreading machine. The tea spreading machine is an automated equipment in the tea making process, mainly used for spreading and killing tea leaves. In the traditional tea making process, spreading tea leaves is a crucial step, which is directly related to the final quality of tea leaves.

[0003] Spreading the tea leaves is an important step in the tea-making process, mainly used in the production of green tea, yellow tea, black tea and Pu'er tea. It is also called spreading and airing, and is the process of spreading the picked fresh tea leaves thinly in a ventilated environment to allow them to naturally release moisture and change from being brittle and hard to wilting and withering.

[0004] After spreading the tea leaves on the conveyor belt of the spreading machine, start the fan below to allow air to circulate through the holes on the conveyor belt to promote the evaporation of the tea leaves. However, when the fan blows air to the tea leaves in a direct blowing manner, the moisture in the tea leaves will evaporate unevenly. When the fan blows air to the tea leaves, the moisture on the surface of the tea leaves will evaporate first, and the water molecules inside the tea leaves need to gradually diffuse to the surface of the tea leaves. It takes time for the water molecules inside the tea leaves to diffuse to the surface. If air is blown at the tea leaves for a long time, the moisture on the surface of the tea leaves will evaporate too quickly, making the surface of the tea leaves over-dry. The internal moisture cannot be taken away in time, causing the tea leaves to wither unevenly. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a tea spreading unit, which aims to improve the problem in the prior art that the fan directly blows air to the tea leaves to promote the evaporation of moisture in the tea leaves, which often causes uneven evaporation of moisture in the tea leaves, resulting in too little or too much moisture in some parts, causing uneven withering of the tea leaves.

In this embodiment, the rotating shaft 19 and the rotating shaft 18 are arranged in a cross shape, and the intersection of the extended lines of the rotating shaft 19 and the rotating shaft 18 coincides with the axis of the driving end of the second motor 16.

[0030] Start the motor 2 16, so that the motor 2 16 drives the driving rod 17 to rotate along the axis of the driving end of the motor 2 16 as the axis, so that the driving rod 17 drives the fixed rod 4 to drive the fan 13 to tilt forward with the rotating shaft 18 as the axis. At the same time, as the driving rod 17 rotates, the fixed rod 4 drives the fan 13 to tilt to the right with the rotating shaft 19 as the axis. As the motor 2 16 continues to drive the driving rod 17 to rotate, the fixed rod 4 will drive the fan 13 to tilt backward again with the rotating shaft 18 as the axis, and as the driving rod 17 continues to rotate, the fixed rod 4 will drive the fan 13 to tilt to the left with the rotating shaft 19 as the axis, thereby realizing the angular swing of the fan 13. The fan 13 swings in a circular shape, so that the fan 13 can intermittently blow air to tea leaves at different positions, so that the water molecules inside the tea leaves have time to diffuse to the surface of the tea leaves, so that the water in the tea leaves evaporates more evenly.

[0031] In this embodiment, the motor of the fan 13 is fixedly mounted on the upper end of the fixing rod 4, and the motor is used to rotate the blades of the fan 13. Moreover, during the movement of the fixing rod 4, it only swings and does not rotate, so the motor of the fan 13 can be directly connected with an electric wire.

[0032] A conveyor belt 7 is fixedly connected inside the chassis 1, and a plurality of evenly distributed through holes 6 are provided on the outside of the conveyor belt 7. When the fan 13 blows air upward, air can circulate through the through holes 6 on the conveyor belt 7 to promote the evaporation of moisture inside the tea leaves on the conveyor belt 7.

[0033] Mounting plates 2 are fixedly connected to the front and rear sides of the middle of the top of the chassis 1, and smoothing rollers 5 are rotatably connected to the opposite sides of the two mounting plates 2. A motor 8 is fixedly connected to one side of one mounting plate 2. The driving end of the motor 8 passes through the mounting plate 2 and is fixedly connected to one side of the smoothing roller 5. Starting the motor 8 drives the smoothing roller 5 to rotate, so that the smoothing roller 5 can smooth the higher piled area of ​​tea leaves at the top of the conveyor belt 7, thereby making the tea leaves spread more evenly on the conveyor belt 7.

[0034] The front and rear sides of the inner wall of the chassis 1 are fixedly connected with a bottom plate 11, the tops of the two bottom plates 11 are fixedly connected with a cylinder 12, and the tops of the two cylinders 12 are fixedly connected with a brush 10. The cylinder 12 is started to push the brush 10 close to the conveyor belt 7. When the conveyor belt 7 rotates, the brush 10 can be used to clean up the tea stems that enter the through hole 6 on the conveyor belt 7.

[0035] Side panels 3 are fixedly connected to both the front and rear sides of the top of the chassis 1. When the tea leaves are spread on the top of the conveyor belt 7, the side panels 3 on both sides of the chassis 1 can be used to prevent the tea leaves from falling from both sides of the chassis 1.

[0036] A collecting box 20 is provided on the inner bottom wall of the chassis 1. The collecting box 20 is only placed on the inner bottom wall of the chassis 1, and there is no connection between the two. The collecting box 20 is placed below the brush 10. When the brush 10 cleans the tea stalks on the surface of the conveyor belt 7, they can fall into the collecting box 20 below for collection and then centralized processing.

[0037] Working principle: drive the conveyor belt 7, then pile the tea leaves on the top of the conveyor belt 7, and use the rotation of the conveyor belt 7 to spread the tea leaves on the top of the conveyor belt 7. At the same time, start the motor 18 to make the motor 18 drive the smoothing roller 5 to rotate. When the conveyor belt 7 drives the tea leaves to pass under the smoothing roller 5, the rotating smoothing roller 5 can smooth the tea leaves piled higher on the top of the conveyor belt 7, so that the tea leaves on the conveyor belt 7 can be spread more evenly. When the conveyor belt 7 rotates, start the fan 13 to make air circulate through the through holes 6 on the conveyor belt 7, assist in spreading the tea leaves on the conveyor belt 7, and promote the evaporation of moisture inside the tea leaves. When the fan 13 makes the air flow, start the motor 2 16 to drive the motor 2 16 to The dynamic driving rod 17 rotates along the central axis of the driving end of the motor 2 16 as the axis, and then the driving rod 17 drives the fixed rod 4 to drive the fan 13 to tilt forward with the rotating shaft 18 as the axis. As the driving rod 17 rotates, the fixed rod 4 drives the fan 13 to tilt to the right with the rotating shaft 19 as the axis. At the same time, as the motor 2 16 continues to drive the driving rod 17 to rotate, the fixed rod 4 will again drive the fan 13 to tilt backward with the rotating shaft 18 as the axis, and as the driving rod 17 continues to rotate, the fixed rod 4 will drive the fan 13 to tilt to the left with the rotating shaft 19 as the axis, so that the fan 13 can intermittently blow air to the tea leaves, so that the moisture inside the tea leaves can evaporate more evenly.
