working principle:

1. The ratchet 300 is driven to reciprocate by the leaf-feeding link mechanism, and the conveyor belt 301 is driven by the ratchet 300 to move in gaps.

2, the cutter body 404 lifting total height is 45 millimeters, and the following 15 millimeters (1/3) have tealeaves, and upper 30 millimeters (2/3) do not have tealeaves. The lifting of the cutter body 404 is driven by the leaf-cutting link mechanism to reciprocate the cutting motion.

3. The first crank 400 and the second crank 302 are installed at both ends of the first drive shaft 200 . The first crank 400 and the second crank 302 are installed at an angle of 60°, and when the second crank 302 is at 0°, the first crank 400 is at 60° (the cutter body 404 has dropped by 1/3 at this time).

4. The first drive shaft 200 rotates clockwise, when the first crank 400 turns from 0° to 180°, the cutter body 404 descends from the highest point to the lowest point. When the first crank 400 turns from 180° to 360°, the cutter body 404 rises from the lowest point to the highest point.

5. When the second crank 302 rotates from 0° to 180°, the ratchet 300 descends from the highest point to the bottom (ratchet return stroke), and the conveyor belt 301 remains still. When the second crank 302 turns from 180° to 360°, the ratchet wheel 300 rises from the lowest point to the highest point (the ratchet wheel rotates), and the conveyor belt 301 rotates.

6. Analysis of the motion coordination between the conveyor belt 301 and the cutter body 404:

(1) When the second crank 302 rotates from 0° to 180°, the ratchet wheel 300 descends from the highest point to the lowest point (ratchet return stroke), and the conveyor belt 301 stands still. And the first crank 400 turns from 60° to 240°, and the cutter body 404 descends from the highest point to the lowest point to complete the leaf cutting and then rises to the 1/3 position point to give way to the tea leaves to be cut on the conveyor belt 301 Through the cutter station.

(2) When the second crank 302 turns from 180° to 360°, the ratchet 300 rises from the lowest point to the highest point (the ratchet rotates), and the conveyor belt rotates. And the first crank 400 turns to 60 ° by 240 °, and the cutter body 404 rises to the highest point from the bottom point to complete the leaf cutting and then descends to the 1/3 position point.

The invention can automatically complete the five steps of whole leaf, transportation, leaf pressing, leaf cutting and leaf extraction, without manpower, efficient work, convenient and fast operation, and can greatly improve the economic benefits of enterprises and tea farmers.
