[0026] like Figure 1-5As shown, a stepped feeding device includes a housing 1, inside which a hopper 2, at least two stepped plates 3 arranged vertically in a stepped structure, and a motor 4 are installed. Inner support shafts 5 and outer support shafts 6 are provided on both sides of the housing. The stepped plates are movably connected to the inner support shafts via connecting components. An upper sliding block 8 and a lower sliding block 9 are movably mounted on the outer support shafts. A fixing block 13 is fixedly mounted on the outer support shaft 6 to ensure that the fixing block 13 cannot move along the outer support shaft. A swing arm 10 is movably mounted on the fixing block 13. The upper sliding block 8 is connected to the swing arm 10 via an upper connecting rod 11, and the lower sliding block 9 is connected to the swing arm 10 via a lower connecting rod 12. The upper connecting rod 11 and the lower connecting rod 12 are located on both sides of the swing arm 10. The number of inner and outer support shafts can be flexibly set. In this embodiment, four inner support shafts and two outer support shafts are provided, arranged in two parallel rows. The stepped plates are V-shaped and installed upside down to facilitate material conveying from bottom to top.

[0027] In two adjacent step plates, one step plate is connected to the upper sliding block 8 through the first connecting rod 20, and the other step plate is connected to the lower sliding block 9 through the second connecting rod 21, forming a linkage relationship, which can form an up-and-down movement.

[0028] The output shaft of motor 4 is equipped with a transmission assembly, which is connected to the lower sliding block 9 via a transmission link 14. A horizontal conveying mechanism 7 is provided on the outside of the housing 1, which connects to the uppermost stepped plate. The motor drives the transmission assembly, which in turn drives the lower sliding block to move up or down via the transmission link. This, in turn, through the action of each link, achieves the reciprocating motion of each stepped plate, realizing the intermittent conveying of materials from bottom to top.

[0029] The lower sliding block 9 is fixedly equipped with a support plate 15. The transmission assembly includes a transmission component fixing plate 19, a main sprocket 22, a tension wheel 23, and a transmission sprocket 24. The main sprocket 22 is mounted on the output shaft of the motor 4. The tension wheel 23 and the transmission sprocket 24 are mounted on the transmission component fixing plate 19 via a rotating shaft. The main sprocket 22, the tension wheel 23, and the transmission sprocket 24 are connected by a chain. A rotating wing plate 25 is mounted on the transmission sprocket 24. One end of the transmission connecting rod 14 is connected to the rotating wing plate 25, and the other end is connected to the support plate 15 via a pin. Motor 4 drives main sprocket 22 to rotate. Main sprocket 22 drives tension wheel 23 and transmission sprocket 24 to rotate via chain. Tension wheel 23 adjusts the tension. The rotation of transmission sprocket 24 causes rotating blade 25 to swing, which in turn causes transmission link 14 to swing, thereby causing support plate 15 to move up and down. Support plate 15 causes lower sliding block 9 to move. Lower sliding block 9 drives upper sliding block 8 to move via lower link 21, swing arm 10, and upper link 20, thereby causing each stepped plate connected to the lower and upper sliding blocks to move. The transmission component fixing plate can be installed at the bottom of the chassis via a column.

[0030] The connecting assembly includes a connecting plate 17 and a seated bearing 18. The connecting plate 17 is connected to the seated bearing 18. The bottom surface of the stepped plate 3 is mounted on the connecting plate 17. The seated bearing 18 is movably mounted on the inner support shaft 5 and can move up and down along the inner support shaft 5, thereby enabling the connecting plate 17 to move up and down. The first connecting rod and the second connecting rod are connected to the connecting plate, and the step plate moves up and down by driving the connecting plate to move up and down.

[0031] The hopper 2 is inclined, and the bottom of the hopper 2 is connected to the lowest step plate 3 inside the chassis 1. One side of the hopper 2 extends upward to the upper edge of the chassis 1, so as to provide a buffer when the material is placed down.

[0032] The chassis 1 is equipped with a return material channel 16, which is located on one side of the stepped plate 3 and extends to the hopper area. When there are unqualified or non-compliant materials, they can be returned to the hopper through the return material channel. Non-compliant materials are those that have accumulated or otherwise become piled up. Sensors or vision components can be installed on one side of the horizontal conveyor mechanism for detection. The material can be pushed by a robot or by a cylinder.

[0033] The middle position of the swing arm 10 is rotatably mounted to the fixed plate via a pin, so that the upper connecting rod 11 and the lower connecting rod 12 are symmetrically distributed, thus better achieving the linkage function.

[0034] The horizontal conveying mechanism 7 includes a conveyor belt and a conveyor motor. Rollers are wound around both sides of the conveyor belt, and one of the rollers is connected to the drive shaft of the conveyor motor. The material conveyed from the stepped plate to the conveyor belt is continued to be conveyed forward and finally conveyed from the conveyor belt to the designated position.

[0035] This embodiment is illustrated using a structure with four stepped plates.

[0036] Four stepped plates are installed sequentially from bottom to top, defined as: first stepped plate, second stepped plate, third stepped plate, and fourth stepped plate. There are two rotating vanes, two drive sprockets, and two drive connecting rods. Two rotating vanes are located on either side of the transmission component fixing plate, and one drive connecting rod is installed for each rotating vane. The two drive connecting rods are connected to both sides of the support plate. There are two first connecting rods and two second connecting rods.

[0037] The first step plate at the bottom is connected to the lower sliding block via a second link, the second step plate is connected to the upper sliding block via a first link, the third step plate is connected to the lower sliding block via a second link, and the fourth step plate is connected to the upper sliding block via a first link.

[0038] Primarily designed for flat and elongated materials. Place the material into the hopper, start motor 4, and the motor will run at the set speed. (Reference) Figure 5 Taking the clockwise rotation direction of the motor output shaft as an example, the motor 4 drives the main sprocket 22 to rotate, which in turn drives the tensioning wheel 23 and the transmission sprocket 24 to rotate. The transmission sprocket 24 drives the rotating blade 25 to rotate, which in turn drives the transmission connecting rod 14 to rotate. During one rotation, the transmission connecting rod 14 will perform a reciprocating motion from top to bottom and then from bottom to top. One rotation is one cycle, which in turn drives the support plate 15 to move up and down, so that the support plate 15 returns to its initial position from top to bottom and then from bottom to top. As the support plate 15 moves downward, it drives the lower sliding block 9 to move downward. The lower connecting rod 12 pulls the connecting end of the swing arm 10 downward, while the connecting end of the swing arm 10 and the upper connecting rod 11 moves upward. The first and third step plates connected to the lower sliding block 9 move downward, while the second and fourth step plates connected to the upper sliding block 8 move upward. The first step plate moves down to below the bottom of the hopper, allowing the material in the hopper 2 to enter the first step plate. The second step plate moves upward while the third step plate moves downward, allowing the material on the second step plate to enter the third step plate. The fourth step plate moves upward and then transports the material to the conveyor belt of the horizontal conveying mechanism, from where it is output. As the rotating blade reaches its lowest position and continues to rotate, the transmission causes its connection with the swing arm to move upward. At the same time, the connection between the swing arm and the upper connecting rod moves downward. This causes the first and third step plates to move upward, while the second and fourth step plates move downward. The material on the first step plate is fed into the second step plate, and the material on the third step plate is fed into the fourth step plate, thus forming a reciprocating intermittent material conveying system, which can effectively solve the problem of material stacking.
