[0019] Examples, such as Figures 1 to 3As shown, an automatic tea typesetting machine is used for orderly typesetting of flat tea such as Taiping Houkui before drying, so as to improve the efficiency and consistency of typesetting and reduce the labor intensity of typesetting. The typesetting machine includes a frame 1, a rotary conveyor belt 2 arranged on the frame 1, and the rotary conveyor belt 2 intermittently moves forward under the control of a control system, and each forward distance is the interval distance between two rows of tea leaves. For the convenience of description, the direction in which the tea leaves move on the rotary conveyor belt 2 is set to the front, and vice versa to the rear.

[0020] A feeding device 3 is arranged above the rotary conveyor belt 2. The feeding device 3 is provided with a group of tea inlet holes 31 arranged side by side along the width direction of the rotary conveyor belt 2. A throwing conveyor belt 4 is arranged at the front end of the tea inlet hole 31 to drive the tea leaves to fly forward quickly. A material drop baffle 5 is arranged in front of the throwing conveyor belt 4. A material drop area 6 is arranged between the material drop baffle 5 and the throwing conveyor belt 4. The length of the dropping area 6 is greater than the length of the tea leaves. After the tea leaves enter the throwing conveyor belt 4 from the tea inlet hole 31, the tea leaves are thrown out under the high-speed operation of the throwing conveyor belt 4. The thrown tea leaves fall into the dropping area 6 under the action of the material drop baffle 5. The length of the throwing conveyor belt 4 is between 120mm and 200mm, and the linear speed of the throwing conveyor belt 4 is greater than 200㎜ / s.

[0021] A group of limit baffles 7 for limiting the left and right swing of tea leaves are also arranged between the drop baffle 5 and the feeding device 3. The limit baffles 7 are arranged on both sides of each tea inlet hole 31, so as to control the position of the tea leaves coming out of each tea inlet hole 31 in the width direction of the rotary conveyor belt 2. The gap between the limit baffle 7 and the throwing conveyor belt 4 is smaller than the thickness of the tea leaves. The limit baffle 7 extends downward from the drop area 6 to the top of the rotary conveyor belt 2 or the top of the tea placement device on the rotary conveyor belt 2. When all the tea inlet holes 31 on the feeding device 3 have completed feeding and the tea leaves are sent to the rotary conveyor belt 2 below the drop area 6 or the tea placement device 30 on the rotary conveyor belt 2 through the throwing conveyor belt 4, the tea placement device 30 is usually a drying screen. The rotary conveyor belt 2 moves forward for a distance and stops, ready to receive the next row of tea leaves.

[0022] The rear end of the feeding device 3 is provided with a feeding platform 10 for stacking untypesetting tea leaves, and the tea inlet hole 31 on the feeding device 3 is adapted to the height of the feeding platform 10 so that the operator can directly push the tea leaves from the feeding platform 10 into the tea inlet hole 3. The operator can stand at the rear end of the frame 1 and both sides of the frame 1 to operate and insert the tea leaves into the tea inlet hole 3, so 3 people can be set to operate at the same time to increase the speed of tea typesetting.

[0023] In order to ensure that the tea leaves in the tea inlet hole 31 can smoothly enter the throwing conveyor belt 4, a feeding roller group 20 is also provided between the feeding device 3 and the throwing conveyor belt 4, which is used to take the tea leaves out of the discharging end of the tea inlet hole 31 at a certain speed and feed them into the throwing conveyor belt 4. The feeding roller group 20 includes an upper feeding roller 21 and a lower feeding roller 22 that cooperate with each other to drive the tea leaves forward. The upper feeding roller 21 and the lower feeding roller 22 are provided with mutually meshing rotating gears. By rotating the gears, the upper feeding roller 21 and the lower feeding roller 22 are synchronously rotated, and the upper feeding roller 21 rotates counterclockwise, and the lower feeding roller 22 rotates clockwise. Furthermore, the feeding roller group 20 acts on the tea leaves with a certain pressure to flatten and shape the tea leaves while driving the tea leaves forward.

[0024] In order to control the up and down movement of the material drop baffle 5 and release the tea leaves when they are conveyed forward, the material drop baffle 5 is also connected to a baffle driving device 8 that drives the material drop baffle 5 to move up and down. When the rotary conveyor belt 2 is started, the baffle driving device 8 drives the material drop baffle 5 to move upward, and when the rotary conveyor belt 2 stops, the baffle driving device 8 drives the material drop baffle 5 back to the initial position, and the baffle driving device 8 stops working.

[0025] As an implementation scheme, the baffle driving device 8 includes driving cylinders (not shown in the figure) acting on both ends of the blanking baffle 5, and the blanking baffle 5 is driven to move up and down by the driving cylinders.

[0026] As another embodiment, the baffle driving device 8 includes a rotating shaft 81, a rotating cam 82 fixedly mounted at both ends of the rotating shaft 81, and support columns 9 are provided at both ends of the blanking baffle 5. The other end of the support column 9 is supported on the circumferential surface of the rotating cam 82. To reduce friction, a roller 91 is provided at one end of the support column 9 that cooperates with the rotating cam 82. The roller 91 rotates with the rotating cam 82. When the tea leaves falling into the blanking area 6 fall into a row, the rotating cam 82 rotates, driving the support column 9 and its blanking baffle 5 to move upward, so that the bottom of the blanking baffle 5 is higher than the height of the tea leaves in the blanking area 6, and at the same time starting the rotary conveyor belt 2. The rotary conveyor belt 2 moves to bring the tea leaves out of the blanking area 6 and then stops. After the rotary conveyor belt 2 stops, the rotating cam 82 drives the blanking baffle 5 back to the initial position (the lowest point) to arrange the next row of tea leaves.

[0027] In order to facilitate the adjustment of the tension of the rotary conveyor belt 2, rotary conveyor rollers 201 are arranged at both ends of the rotary conveyor belt 2, and a first mounting plate 11 for supporting the rotary conveyor roller 201 is arranged on the frame 1. The first mounting plate 11 is provided with a transverse waist-shaped adjustment hole 12 in the horizontal direction for adjusting the front and rear positions of the rotary conveyor roller 201. Bearing seats 202 are arranged at both ends of the rotary conveyor roller 201, and the bearing seats 202 are fixedly mounted on the transverse waist-shaped adjustment hole 12 by bolts.

[0028] In order to facilitate the adjustment of the height of the rotary conveyor belt 2 , a vertical waist-shaped adjustment hole 13 is further provided on the first mounting plate 11 . The first mounting plate 11 is fixedly mounted on the frame 1 by bolts in cooperation with the vertical waist-shaped adjustment hole 13 for adjusting the height of the rotary conveyor belt 2 .

[0029] Similarly, in order to facilitate the adjustment of the tension of the throwing conveyor belt 4, throwing conveyor shafts 41 are provided at both ends of the throwing conveyor belt 4, and the frame 1 is provided with an adjusting bolt 14 for adjusting the position of one of the throwing conveyor shafts 41. The end of the adjusting bolt 14 is fixedly connected to the throwing conveyor shaft 41, and a threaded hole matching the adjusting bolt 14 is provided on the frame 1.
