After the placement is completed, the rotary conveyor belt moves forward again, and finally the neat placement of the tea leaves is completed. The present invention has good tea placement neatness, high placement efficiency, and simple operation. The operator does not need to spend too much mental labor, and only needs to insert the tea leaves into the pinching feed hole.

[0011] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the three-dimensional structure of the utility model.

[0013] Figure 2 It is a cross-sectional view of the present utility model.

[0014] Figure 3It is a schematic diagram of the three-dimensional structure of the feeding device and the forming feeding roller group in the utility model. DETAILED DESCRIPTION

[0015] Examples, such as Figures 1 to 3 As shown, a flat tea forming and typesetting machine is used to arrange flat teas, such as Taiping Houkui tea, in an orderly manner before drying. This improves typesetting efficiency and consistency and reduces typesetting labor. The machine comprises a frame 1 and a rotary conveyor belt 2 mounted on the frame. Controlled by a control system, the rotary conveyor belt 2 intermittently moves forward, each advance distance corresponding to the distance between two rows of tea leaves. For ease of description, the direction of movement of the tea leaves on the rotary conveyor belt 2 is assumed to be forward, and the reverse direction is assumed to be backward.

[0016] A feeding device 3 is located above the rotating conveyor belt 2. The feeding device 3 has a set of pointed feed holes 31 arranged side by side along the width of the rotating conveyor belt 2. A tossing conveyor belt 4 is located at the front end of the pointed feed holes 31, driving the tea leaves forward at a rapid speed. A drop plate 5 is located in front of the tossing conveyor belt 4, and a drop area 6 is defined between the drop plate 5 and the tossing conveyor belt 4. The drop area 6 is longer than the length of the tea leaves. After the tea leaves enter the tossing conveyor belt 4 through the pointed feed holes 31, the high-speed operation of the tossing conveyor belt 4 ejects the tea leaves, which are then ejected by the drop plate 5 and fall into the drop area 6. The tossing conveyor belt 4 is between 120 mm and 200 mm long, and its linear speed is greater than 200 mm / s.

[0017] A set of limit baffles 7 are also provided between the drop baffle 5 and the feed mechanism 3 to prevent the tea leaves from swinging left and right. These limit baffles 7 are located on either side of each pinch feed hole 31, thereby controlling the position of the tea leaves emerging from each pinch feed hole 31 across the width of the rotary conveyor belt 2. The gap between the limit baffles 7 and the delivery conveyor belt 4 is less than the thickness of the tea leaves. The limit baffles 7 extend downward from the drop area 6 to above the rotary conveyor belt 2 or above the tea placement device on the rotary conveyor belt 2. When all the pinch feed holes 31 on the feed mechanism 3 have finished feeding and the tea leaves have been delivered by the delivery conveyor belt 4 to the rotary conveyor belt 2 below the drop area 6 or to the tea placement device 30 on the rotary conveyor belt 2, which is typically a drying and screening device, the rotary conveyor belt 2 moves forward a distance and stops, preparing to receive the next row of tea leaves.

[0018] The rear end of the feed mechanism 3 is provided with a feed platform 10 for stacking untyped tea leaves. The pinched feed hole 31 on the feed mechanism 3 is height-matched to the feed platform 10, allowing operators to push tea leaves directly from the feed platform 10 into the pinched feed hole 3. Operators can stand at the rear end or on both sides of the frame 1 to insert tea leaves into the pinched feed hole 3. Therefore, three people can be set up to operate simultaneously, thereby increasing the speed of tea typesetting.

[0019] To ensure that the tea leaves in the pinched feed hole 31 can smoothly enter the delivery conveyor 4, a forming roller assembly 20 is provided between the feed device 3 and the delivery conveyor 4. This assembly is used to convey the tea leaves from the delivery end of the pinched feed hole 31 at a predetermined speed and onto the delivery conveyor 4. The forming roller assembly 20 comprises an upper forming roller 21 and a lower forming roller 22, which cooperate to drive the tea leaves forward. The upper and lower forming rollers 21 and 22 are equipped with intermeshing gears, which rotate synchronously, with the upper forming roller 21 rotating counterclockwise and the lower forming roller 22 rotating clockwise. Furthermore, while conveying the tea leaves forward, the forming roller assembly 20 also applies pressure to the tea leaves, flattening them into shape.

[0020] To control the up and down movement of the drop baffle 5 and release the tea leaves as they are conveyed forward, the drop baffle 5 is further connected to a baffle drive device 8 that drives the drop baffle 5 up and down. When the rotary conveyor belt 2 starts, the baffle drive device 8 drives the drop baffle 5 upward. When the rotary conveyor belt 2 stops, the baffle drive device 8 drives the drop baffle 5 back to its initial position and stops working.

[0021] 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 driving cylinders drive the blanking baffle 5 to move up and down.

[0022] As another implementation, the baffle driving device 8 comprises a rotating shaft 81, rotating cam 82 fixedly installed at both ends of the rotating shaft 81, support columns 9 arranged at both ends of the blanking baffle 5, and the other ends of the support columns 9 supported on the circumferential surface of the rotating cam 82. In order to reduce the friction, a roller 91 is arranged at the end of the support column 9 matched with the rotating cam 82, and the roller 91 is rotationally matched with the rotating cam 82. When the tea leaves falling into the blanking area 6 fall into a row, the rotating cam 82 rotates to drive the support column 9 and the 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. At the same time, the rotary conveying belt 2 is started, and the rotary conveying belt 2 moves to take out the tea leaves from the blanking area 6 and then stops. After the rotary conveying belt 2 stops, the rotating cam 82 drives the blanking baffle 5 to return to the initial position (the lowest point) to arrange the next row of tea leaves.

[0023] In order to conveniently adjust the tension of the rotary conveying belt 2, rotary conveying rollers 201 are arranged at both ends of the rotary conveying belt 2, a first mounting plate 11 for supporting the rotary conveying rollers 201 is arranged on the frame 1, horizontal waist-shaped adjusting holes 12 for adjusting the front and back positions of the rotary conveying rollers 201 are arranged on the first mounting plate 11 in the horizontal direction, and bearing seats 202 are arranged at both ends of the rotary conveying rollers 201 and fixedly installed on the horizontal waist-shaped adjusting holes 12 through bolts.

[0024] In order to conveniently adjust the height of the rotary conveying belt 2, vertical waist-shaped adjusting holes 13 are further arranged on the first mounting plate 11, and the first mounting plate 11 is fixedly installed on the frame 1 through bolts matched with the vertical waist-shaped adjusting holes 13 for adjusting the height of the rotary conveying belt 2.

[0025] Similarly, in order to conveniently adjust the tension of the throwing conveying belt 4, throwing conveying shafts 41 are arranged at both ends of the throwing conveying belt 4, adjusting bolts 14 for adjusting the position of one of the throwing conveying shafts 41 are arranged on the frame 1, the end of the adjusting bolt 14 is fixedly connected with the throwing conveying shaft 41, threaded holes matched with the adjusting bolt 14 are arranged on the frame 1, and the throwing conveying shaft 41 can be moved back and forth by rotating the adjusting bolt 14.

[0026] The utility model is described exemplarily above by combining with the drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned mode. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the above-mentioned concept and technical scheme of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
