[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Embodiment 1:

[0017] like Figure 1-3As shown, it includes a bottom plate, a conveyor belt 1, a transition plate 2 and a stacking plate 3 which are sequentially arranged on the bottom plate. The transition plate 2 is a cross-shaped plate structure and is rotatably arranged at the rear end of the conveyor belt 1. When the plate body on the transition plate 2 is in a horizontal state, it is lower than the conveying surface of the conveyor belt 1. The stacking plate 3 slides vertically on the side of the transition plate 2 away from the conveyor belt 1. The stacking plate 3 in the initial horizontal state is lower than the plate body in the horizontal state on the transition plate 2. A driving mechanism for controlling the transmission of the transition plate 2 and the stacking plate 3 is provided on the bottom plate. The cardboard transported from the conveyor belt 1 is transitionally transported by utilizing the cooperation of the transition plate 2, the stacking plate 3 and the driving mechanism to avoid the cardboard directly falling on the stacking plate 3, so as to ensure that the cardboard on the stacking plate 3 has time to be removed after being stacked to a certain extent, and at the same time, it can ensure that the cardboard falling from the transition plate 2 is always higher than the surface of the stacking plate 3 and the highest layer of cardboard on the stacking plate 3, and can also be automatically unloaded after a fixed amount of paper stacks are stacked on the stacking plate 3, and the stacking plate 3 is emptied for the next automatic stacking and sorting.

[0018] Embodiment 2:

[0019] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the driving mechanism includes a main gear 4 fixedly sleeved on the mounting shaft of the transition plate 2, two vertical plates are provided on the bottom plate, and a transition gear 5 and an adjusting gear 6 that mesh with each other are rotatably provided on the vertical plates. Adjusting rods 7 are vertically slidably provided on both sides of the stacking plate 3 on the bottom plate, and the adjusting rods 7 are rotatably arranged with the stacking plate 3. A vertical row of adjusting tooth grooves are provided on the adjusting rods 7, and the transition gear 5 meshes with the main gear 4, and the adjusting gear 6 meshes with the adjusting tooth grooves. A motor for controlling the transition plate 2 is installed on one of the vertical plates, and the main gear 4 is a half gear, and the diameter of the main gear 4 is smaller than the diameter of the adjusting gear 6. The driving mechanism composed of the main gear 4, the transition gear 5, the adjusting gear 6 and the adjusting rod 7 is utilized to realize that when the transition plate 2 rotates to transitionally transport the cardboard, the stacking plate 3 can be driven to move downward synchronously by a moving distance, so as to ensure that the highest surface of the stacking plate 3 stacked with cardboard is always lower than the transition plate 2 and is in a horizontal state below the plate body, wherein the transition gear 5 ensures that the main gear 4 and the adjusting gear 6 rotate in the same direction, so that when the transition plate 2 rotates forward, the stacking plate 3 is in a downward state.

[0020] Embodiment 3:

[0021] The technical solution is basically the same as that of the first embodiment, except that Figure 3As shown, a vertical guide rod 8 is provided on the bottom plate, and a guide groove for the guide rod 8 is provided in the adjusting rod 7. A return spring 9 is sleeved on the rod body of the guide rod 8 located between the bottom plate and the bottom end of the adjusting rod 7, wherein the main gear 4 is a half gear to ensure the resetting of the stacking plate 3. When the smooth surface of the main gear 4 rotates to a position relative to the transition gear 5, the adjusting rod 7 is moved upward under the action of the return spring 9, and the stacking plate 3 is moved upward. At the same time, when the transition gear 5 and the adjusting gear 6 are meshed and reversed, the forward rotation of the main gear 4 will not be affected, until the transition gear 5 is re-engaged with the main gear 4, so as to facilitate the next cardboard stacking and transportation.

[0022] Embodiment 4:

[0023] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the bottom plate is located below the stacking plate 3, the top surface of the plate body is an inclined surface and the bottom end faces the transition plate 2, and a mounting strip is provided sliding along the inclined surface, and a pressure sensor 11 abutting against the bottom surface of the stacking plate 3 is installed on the mounting strip, and the bottom surface of the end of the stacking plate 3 away from the adjusting rod 7 is connected to the mounting strip by a connecting rope 10, a coil spring 13 is sleeved on the rotating shaft of the stacking plate 3, and an electric push rod 12 with a telescopic end fixedly connected to the mounting strip is horizontally installed on the bottom plate, the output end of the pressure sensor 11 is electrically connected to the input end of the processor, the output end of the processor is electrically connected to the input end of the relay, and the output end of the relay is electrically connected to the electric push rod 12. By utilizing the cooperation of the pressure sensor 11 and the electric push rod 12, when the stacking plate 3 moves down to a certain position, the pressure sensor 11 is pressed against the adjusting rod 7, and the pressure sensor 11 is pressed against the adjusting rod 7. After the position is determined, the pressure sensor 11 is triggered, and the pressure sensor 11 transmits the signal to the processor for processing. Then the processor sends an instruction to the electric push rod 12, controlling its contraction to move with the mounting bar, and pulling the end of the stacking board 3 away from the rotating shaft through the connecting rope 10 to swing downward, so that the fixed amount of cardboard stacked on the stacking board 3 automatically falls down. When the electric push rod 12 initially contracts and pulls the mounting bar to move, the connecting rope 10 is in a relaxed state. The initial contraction amount of the electric push rod 12 is used to straighten the connecting rope 10 so as to pull the stacking board 3. At the same time, when the mounting bar and the pressure sensor 11 thereon slide on the inclined surface, the distance between the pressure sensor 11 and the bottom surface of the stacking board 3 gradually increases, so that the stacking board 3 is pulled down.

[0024] Working principle: When stacking cardboards, start the conveyor belt 1 and the motor at the same time, and the cardboards fall from the conveyor belt 1 between the adjacent plates on the transition plate 2, and move down with the adjusting rod 7 through the transition gear 5 and the adjusting gear 6, so that the cardboards falling from the transition plate 2 are stacked on the stacking plate 3 piece by piece. When the stacking plate 3 moves down to a certain position, it triggers the pressure sensor 11, and the pressure sensor 11 transmits the signal to the processor for processing. Then the processor sends an instruction to the electric push rod 12, which controls its contraction and moves with the mounting bar. The end of the stacking plate 3 away from the rotating shaft is pulled downward by the connecting rope 10, so that the fixed amount of cardboard stacked on the stacking plate 3 automatically falls down. After falling, the electric push rod 12 is controlled to extend, and then the mounting bar is pushed to reset. At the same time, the connecting rope 10 is relaxed again. Under the action of the coil spring 13, the stacking plate 3 is restored to a horizontal state to facilitate the next stacking.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
