The guiding strip 11 is inclined and is used for guiding the materials so that the materials are closer to the workers and are convenient for taking.

[0038] Further, the above-mentioned conveying device includes a placement plate 4 installed on one side of the first conveyor belt 1. The placement plate 4 is used to provide a platform for workers to operate. The bottom of the placement plate 4 is supported and fixed by the frame. At the same time, the placement plate 4 is divided into five workstations by the frame, and the number of workstations corresponds to the number of second conveyor belts 2.

[0039] Furthermore, the above-mentioned conveying device also includes a baffle 5 installed at the top of the output end of the fifth group of second conveyor belts 2. The baffle 5 is used to prevent the boxes from falling.

[0040] Specifically, the above-mentioned conveying device includes five groups of mounting plates 6. The five groups of mounting plates 6 are respectively installed on the side of the five groups of second conveyor belts 2 away from the placement plate 4. Photoelectric sensors 61 for detecting boxes are installed on the mounting plates 6. When the last group of photoelectric sensors 61 detects a box, the last group of second conveyor belts 2 stops transporting. Then, when the penultimate group of photoelectric sensors 61 detects a box, the penultimate group of second conveyor belts 2 stops conveying to prevent the boxes from piling up. And when the box in the back is taken away, the corresponding second conveyor belt 2 starts again until the photoelectric sensor 61 detects the box again and the corresponding second conveyor belt 2 stops again.

[0041] Please refer to Figure 2 and Figure 3, the five groups of second conveyor belts 2 in the above-mentioned conveying device are all provided with a first side plate 7, and two groups of mounting brackets 71 are installed on the side of the first side plate 7 away from the placement plate 4, and the mounting bracket 71 is installed on the top of the second conveyor belt 2, and the mounting bracket 71 is used to fix the position of the first side plate 7. A clearance hole 72 is opened at the position corresponding to the first side plate 7 and the photoelectric sensor 61, so that the mounting bracket 71 will not hinder the detection effect of the photoelectric sensor 61. A second side plate 8 is also provided on the top of each group of second conveyor belts 2, and the second side plate 8 is arranged between the placement plate 4 and the first side plate 7, and the first side plate 7 and the second side plate 8 are used to prevent the box body from falling during the movement. Two groups of first fixing blocks 81 are fixedly connected to the bottom of the second side plate 8, and a positioning rod 82 is fixedly connected to the first fixing block 81. Both ends of the positioning rod 82 are rotatably connected to the second fixing block 83, and the second fixing block 83 is fixedly connected to the top of the second conveyor belt 2, so that the second side plate 8 can rotate with the positioning rod 82 as the axis, so that the second side plate 8 will not affect the workers to take the box body after rotating to a horizontal state.

[0042] Further, such as Figure 4 and Figure 5 As shown, the above-mentioned conveying device also includes a flipping mechanism 9 for driving the second side plate 8 to flip, and the flipping mechanism 9 includes a third fixed block 91, a rotating rod 92, and a fan-shaped toothed ring 93. Two groups of third fixed blocks 91 are fixedly connected to the bottom of the second side plate 8, and the two groups of third fixed blocks 91 are commonly fixedly connected to the rotating rod 92. The positioning rod 82 is coaxially arranged with the rotating rod 92, and the rotating rod 92 is fixedly connected to the fan-shaped toothed ring 93. When the fan-shaped toothed ring 93 rotates, it drives the second side plate 8 to rotate synchronously. The flipping mechanism 9 also includes a clearance groove 94, a slide 95, a slider 96, and a rack 97. The clearance groove 94 is opened on the second conveyor belt 2 at a position corresponding to the fan-shaped toothed ring 93. The inner wall of the clearance groove 94 is also opened with two groups of symmetrical and inclined slide grooves 95, and the two groups of slide grooves 95 are slidably connected with the slider 96. The rack 97 is fixedly connected between the two groups of sliders 96, and the rack 97 moves smoothly under the limiting action of the slide groove 95 and the slider 96. The sector gear ring 93 is meshed with the rack 97, and the rack 97 drives the sector gear ring 93 to rotate when it moves. The turnover mechanism 9 also includes a first push rod motor 98 installed on the second conveyor belt 2, and the output end of the first push rod motor 98 is fixedly connected to the rack 97, and the first push rod motor 98 is used to drive the rack 97 to move after starting.

[0043] Finally, see Figure 6, the above-mentioned conveying device includes a box loading mechanism 10 arranged on one side of the input end of the second conveyor belt 2. The box loading mechanism 10 is installed on the top of the first conveyor belt 1, and the box loading mechanism 10 is used to realize the automatic output of the boxes. The box loading mechanism 10 includes a fixing plate 101 installed on the top of the first conveyor belt 1 through a frame, and the position of the fixing plate 101 is fixed. Two groups of connecting plates 102 are fixedly connected to the top of the fixing plate 101. One group of bottom plates 103 are respectively fixedly connected to the tops of the two groups of connecting plates 102. Two groups of limiting rods 104 are respectively fixedly connected to the tops of the two groups of bottom plates 103. Multiple boxes are stacked between the four groups of limiting rods 104, and the limiting rods 104 limit the boxes. Two groups of pulleys 105 are rotatably connected between the two groups of connecting plates 102, and the pulleys 105 rotate in place. A synchronous belt 106 is sleeved and installed on the two groups of pulleys 105, and the pulley 105 drives the synchronous belt 106 to move when rotating. A pushing block 107 is fixedly connected to the synchronous belt 106, and the synchronous belt 106 drives the pushing block 107 to move synchronously when moving. Thus, when the pushing block 107 moves, it can push the lowermost group of boxes onto the second conveyor belt 2 to realize the automatic feeding of the boxes. A servo motor 108 is also installed on the top of the fixing plate 101. The output end of the servo motor 108 penetrates through the connecting plate 102 and is fixedly connected to the pulley 105. The servo motor 108 is used to drive the pulley 105 to rotate and then make the synchronous belt 106 start to move. Second push rod motors 109 are installed on both sides of the two groups of connecting plates 102 away from each other. The output end of the second push rod motor 109 is fixedly connected to a push plate, and the push plate is slidably connected in the bottom plate 103, so that the whole box moves upward, making the bottom of the lowermost group of boxes higher than the top of the second conveyor belt 2, which is convenient to push the boxes onto the second conveyor belt 2.

[0044] In this embodiment, first, the worker puts multiple boxes between the four groups of limiting rods 104 at one time. After the second push rod motor 109 extends, it drives the positions of multiple groups of boxes to rise simultaneously, so that the bottom of the box is higher than the position of the second conveyor belt 2. Then the servo motor 108 is started to drive the pulley 105 to rotate. At the same time, the synchronous belt 106 moves and drives the push block 107 to move. When the push block 107 moves, it pushes the lowermost group of boxes onto the second conveyor belt 2, facilitating the second conveyor belt 2 to convey the boxes backward. The worker is located on the side of the placing plate 4 away from the first conveyor belt 1. The second conveyor belt 2 conveys the boxes of tea. The boxes of tea are blocked by the baffle 5 and will not fall when they move to the position of the baffle 5. At this time, the fifth group of photoelectric sensors 61 detects the box, and the fifth group of the second conveyor belt 2 stops working, but the first four groups of the second conveyor belt 2 continue to work. When the fourth group of photoelectric sensors 61 detects the box, the fourth group of the second conveyor belt 2 stops working, but the first three groups of the second conveyor belt 2 continue to work. And so on, until all five groups of photoelectric sensors 61 detect the boxes, the five groups of the second conveyor belt 2 stop working simultaneously. At the same time, when the second conveyor belt 2 stops working, the rack 97 in the corresponding flipping mechanism 9 contracts and drives the rack 97 to move at the same time. The rack 97 moves under the limiting action of the chute 95 and the slider 96. At the same time, when the rack 97 moves, it meshes with the sector gear ring 93, thereby driving the sector gear ring 93 to rotate. At this time, the sector gear ring 93 drives the second side plate 8 to rotate through the rotating rod 92 and the third fixing block 91. At this time, the second side plate 8 rotates around the positioning rod 82. After the second side plate 8 is rotated to the horizontal state, the first push rod motor 98 stops. At this time, it is convenient for the worker to take the box onto the placing plate 4. At this time, the first conveyor belt 1 continues to convey the small packages of tea. The worker takes the small packages on the first conveyor belt 1 onto the placing plate 4 and packs them in the boxes. And the box body can be taken down on the third conveyor belt 3, and multiple boxes are placed in each box body to complete the multi-stage packaging operation of tea.

[0045] The above specific embodiment is only an optional embodiment of the present invention.
