[0019] Example like Figure 1 and Figure 2 As shown, the present invention proposes an automatic unloading device for turnover boxes, including a support frame 1. A roller conveyor belt 2 is fixedly installed on the upper surface of the support frame 1. The roller conveyor belt 2 includes a drive motor, a conveyor wheel and a transmission belt, which can realize the automatic conveying of turnover boxes. A guide groove 3 is opened on one side of the roller conveyor belt 2, and a first toothed rack 4 is fixedly installed on the bottom surface of the roller conveyor belt 2.

[0020] Furthermore, a frame 5 is provided on one side of the roller conveyor belt 2, and a set of guide pulleys 11 are rotatably provided on one side of the frame 5. The guide pulleys 11 are slidably connected to the guide grooves 3, which can guide the frame 5 and facilitate the adjustment of the position of the frame 5. A motor 6 and a commutator 7 are fixedly installed on the frame 5. The output end of the motor 6 is connected to the commutator 7, which can change the output direction of the motor 6. A first gear 8 is fixedly connected to one end of the commutator 7. The first gear 8 is meshed with the first rack 4, which can drive the first gear 8 to cooperate with the first rack 4 to adjust the position of the frame 5.

[0021] like Figure 3 and Figure 4As shown, a tilting assembly 9 for unloading turnover boxes is provided above the roller conveyor belt 2. The tilting assembly 9 includes a set of fixed rods 91, each with a groove. The inner wall of each fixed rod 91 has a guide groove 12. A shaft 92 is rotatably mounted on one end of each fixed rod 91. A set of second gears 93 are fixedly sleeved on the outer wall of the shaft 92, which can drive the shaft 92 to rotate stably on the fixed rods 91. A set of fixed blocks 94 are provided between the fixed rods 91, and the fixed blocks 94 are fixedly sleeved with the shaft 92, which can drive the shaft 92 to rotate. The fixed blocks 94 have grooves 12 on them. There is an installation slot 95, and a threaded sleeve rod 96 is rotatably installed in the installation slot 95 via a bearing seat, so that the threaded sleeve rod 96 rotates stably on the fixed block 94. The outer wall of the threaded sleeve rod 96 is threadedly fitted with a threaded sleeve block 97, so that the threaded sleeve rod 96 can drive the threaded sleeve block 97 to move vertically up and down, thereby adjusting the position of the limit strip 98 to adapt to different specifications of turnover boxes. One end of the threaded sleeve block 97 is fixedly provided with a limit strip 98, which can lock the side of the turnover box. Multiple connecting plates 99 are fixedly installed between the fixed blocks 94, which can drive the fixed blocks 94 to move simultaneously through the connecting plates 99.

[0022] Secondly, the flipping assembly 9 also includes a first electric push rod 910 fixedly installed on the frame 5. The output end of the first electric push rod 910 is fixedly connected to a push rod 911. The first electric push rod 910 can push the push rod 911 to move stably. The two ends of the push rod 911 are respectively fixedly connected to a second rack 912. The second rack 912 is slidably disposed in the fixed rod 91, and the second rack 912 is meshed with the second gear 93. The second rack 912 can push the second gear 93 to rotate stably, thereby realizing the flipping of the turnover box. Guide blocks 13 are respectively fixedly disposed on both sides of the second rack 912. The guide blocks 13 are slidably connected to the guide groove 12, which can guide the second rack 912 and make its movement more stable.

[0023] like Figure 3 and Figure 5 As shown, the frame housing 5 is provided with a drive assembly 10 for driving the tilting assembly 9 to rise and fall. The drive assembly 10 includes a second electric push rod 101 fixedly installed on the frame housing 5. The output end of the second electric push rod 101 is fixedly connected to a connecting seat 102. One end of the connecting seat 102 is rotatably connected to a first push plate 103 through a pin. One end of the first push plate 103 is rotatably connected to the frame housing 5 through a pin, which can position the first push plate 103. The other end of the first push plate 103 is fixedly connected to a fixed rod 91, which can push the fixed rod 91 to rise and fall.

[0024] Furthermore, the drive assembly 10 also includes a second push plate 104 rotatably mounted on the frame 5 via a pin, which can limit the second push plate 104. One end of the second push plate 104 is fixedly connected to the fixed rod 91, which can push the fixed rod 91 up and down, thereby facilitating the adjustment of the unloading position of the flipping assembly 9.

[0025] The working principle of this embodiment is as follows: First, the threaded sleeve rod 96 is rotated according to the height of the turnover box to be unloaded. Since the threaded sleeve rod 96 and the threaded sleeve block 97 are threadedly connected, the threaded sleeve block 97 moves vertically along the mounting through groove 95 during the rotation, thereby driving the limit strip 98 fixed at one end to rise and fall synchronously until the height of the limit strip 98 matches the side of the turnover box, so that the turnover box can be stably locked and the adaptation adjustment of turnover boxes of different specifications can be completed.

[0026] Subsequently, the second electric push rod 101 of the drive assembly 10 on the frame 5 is activated. The output end of the second electric push rod 101 pushes the connecting seat 102 to move. The connecting seat 102 drives the first push plate 103 to rotate around the pin connected to the frame 5 as a fulcrum. At the same time, the fixing rod 91 drives the second push plate 104 to rotate synchronously around the pin on the frame 5 as a fulcrum. Under the coordinated action of the first push plate 103 and the second push plate 104, the fixing rod 91 drives the entire tilting assembly 9 to rise smoothly.

[0027] Next, the motor 6 on the frame housing 5 is started. The output torque of the motor 6 is changed in direction by the commutator 7, driving the first gear 8 to rotate. Since the first gear 8 is meshed with the first rack 4 on the bottom surface of the roller conveyor belt 2, the rotation of the first gear 8 drives the frame housing 5 to move along the length direction of the first rack 4. At the same time, the guide pulley 11 on one side of the frame housing 5 is embedded in the guide groove 3 of the roller conveyor belt 2 and slides, providing guidance and limiting for the movement of the frame housing 5. The frame housing 5 synchronously drives the tilting assembly 9 and the drive assembly 10 to move until the tilting assembly 9 reaches the unloading position. The second electric push rod 101 is started again, causing the second electric push rod 101 to retract, driving the tilting assembly 9 to slowly descend through the connecting seat 102 and the first push plate 103 until the limiting strip 98 is in contact with the upper surface of the roller conveyor belt 2.

[0028] Next, the filled turnover box is placed at the input end of the roller conveyor belt 2, and the drive motor of the roller conveyor belt 2 is started. The drive motor drives the conveyor wheel and the transmission belt to rotate, and the turnover box is automatically conveyed towards the flipping assembly 9 under the drive of the roller conveyor belt 2. When the turnover box moves between the limit clips 98 of the flipping assembly 9, the first electric push rod 910 in the flipping assembly 9 is activated. The output end of the first electric push rod 910 pushes the push rod 911 to move horizontally. The push rod 911 drives the second rack 912, which is fixed at both ends, to slide along the guide groove 12 in the fixed rod 91. Since the second rack 912 meshes with the second gear 93 on the shaft 92, the movement of the second rack 912 drives the second gear 93 to rotate, thereby driving the shaft 92 to rotate stably on the fixed rod 91. The shaft 92 synchronously drives the fixed block 94 to rotate. The fixed block 94 drives the turnover box to flip together through the limit clips 98, and the material in the turnover box is dumped out under the action of gravity.

[0029] The above specific embodiments are merely optional embodiments of the automatic unloading device for turnover boxes of this utility model.
