[0007] See also Figure 1The present invention discloses an automatic trough end leveling device, comprising a conveying trough 26, and a top plate 23 is arranged on the top of one side of the conveying trough 26. A first fixed plate 11 and a second fixed plate 20 are respectively installed on the upper ends of both sides of the port of the conveying trough, and the two are connected to each other through two connecting rods 15; the two ends of the rear end shaft 24 of the leveling swing frame 16 are rotatably supported between the first fixed plate 11 and the second fixed plate 20, and the front end of the leveling swing frame 16 is hinged with a swing arm shaft 17 at the top of the leveling fixed frame 18, and a leveling plate 19 is installed on the leveling fixed frame 18; a tension spring is connected between the leveling swing frame 16 and the leveling fixed frame 18; a swing arm 25 is fixed at one end of the swing arm shaft 17, and the top end of the swing arm 25 is hinged with the first fixed plate 11 through a second connecting rod 14; one side of the leveling swing frame 16 is connected to the power device through a cam transmission mechanism, and the front end of the leveling swing frame 16 is driven to swing up and down around the rear end shaft 24.

[0008] The cam transmission mechanism includes a cam 7, a bearing 8, a rocker arm 9 and a first connecting rod 10. The cam 7 is fixed on the driving shaft 6, and the driving shaft 6 is fixed on the frame through two bearings with seats. The fulcrum of the lever-type rocker arm 9 is rotatably mounted on the frame. The bearing 8 is mounted on the shorter end (the left end in the figure) of the rocker arm 9 and corresponds to the cam 7. The longer end (the right end in the figure) of the rocker arm 9 is hinged to the upper flush swing frame 16 through the first connecting rod 10.

[0009] The power device includes a servo motor 1, a motor fixing plate 2, a driving sprocket 3, a transmission chain 4, and a driven sprocket 5. The servo motor 1 is fixed on the motor fixing plate 2, and the motor fixing plate 2 is fixed to the frame with bolts; the driving sprocket 3 is installed on the output shaft of the servo motor 1, the driven sprocket 5 is fixed on the driving shaft 6, and the transmission chain 4 is connected between the driving sprocket 3 and the driven sprocket 5.

[0010] A guide rail 22 is installed at the upper end of both sides of the port of the conveying trough (one of the guide rails 22 is installed on the top plate 23), and one side of the first fixed plate 11 (the back of the first fixed plate 11 in the figure) is slidably installed on the corresponding guide rail 22 through a slider; the top of the second fixed plate 20 is connected to the horizontally arranged third fixed plate 21 (the two can be an integral structure), and the bottom of the third fixed plate 21 is slidably installed on the guide rail 22 through a slider. A nut is connected to the front end of the first fixed plate 11, and the nut is screwed into the top end of the adjusting screw 12. The adjusting screw 12 is rotatably connected to the screw fixing plate 13, and the screw fixing plate 13 is connected to the frame; an adjusting hand wheel is provided at the other end of the adjusting screw 12. The distance between the screw fixing plate 13 and the first fixed plate 11 can be adjusted by rotating the adjusting screw 12, so as to achieve the effect of aligning surfaces of different lengths.

[0011] The working process of the present invention is as follows: when the servo motor 1 is powered on, the driving sprocket 3 provides power to the driven sprocket 5 through the transmission chain 4, the driving shaft 6 rotates, and the cam 7 is on the driving shaft 6, and the cam 7 rotates accordingly. The shorter end of the rocker arm 9 is equipped with a bearing 8, and the bearing 8 contacts the cam 7. When the cam 7 rotates, the rocker arm 9 is driven to swing up and down. The first connecting rod 10 is fixed to the longer end of the rocker arm 9, and the other end of the first connecting rod 10 is connected to the flush swing frame 16 through a joint bearing. When the rocker arm 9 swings up and down with the rotation of the cam 7, the first connecting rod 10 drives the flush swing frame 16 to move up and down. Since the second connecting rod 14 connects the first fixed plate 11 and the swing arm shaft 17, and the flush swing frame 16 is connected to the flush fixed frame 18 by a tension spring (so that the bottom end of the flush fixed frame 18 is subjected to the elastic force of the tension spring to the left), when the flush swing frame 16 moves upward, one end of the second connecting rod 14 is fixed to the first fixed plate 11 at a certain position, and the other end pulls the swing arm shaft 17, so the swing arm shaft 17 rotates. The movable and limited position can drive the flush surface fixing frame 18 and the flush panel 19 to rotate counterclockwise with the swing arm shaft 17 as the center axis, so that the lower end of the flush panel 19 swings to the right, so that the flush panel 19 leaves the slot; when the flush surface swing frame 16 is downward, one end of the second connecting rod 14 is fixed to the first fixed plate 11 at a certain position, and the other end pulls the swing arm shaft 17, so the swing arm shaft 17 rotates, and due to the rotation of the swing arm shaft 17 and the tension of the tension spring, the flush surface fixing frame 18 and the flush panel 19 are driven to rotate clockwise with the swing arm shaft 17 as the center axis to return to Figure 1 In the state shown, the flush panel 19 is blocked at the slot mouth for tidying up the materials.
