[0039] Two slide rails 33 are fixedly connected to the front side of the top of the base plate 5, and the first screw rods 34 are rotatably connected inside the two slide rails 33. A moving block 35 is slidably connected inside the two slide rails 33. The two first screw rods 34 respectively penetrate the two moving blocks 35 and are threadedly connected to the two moving blocks 35. One end of one of the slide rails 33 is fixedly connected to the second motor 38, and the output end of the second motor 38 is fixedly connected to one of the first screw rods 34. The two first screw rods 34 away from the second motor 38 respectively penetrate the two slide rails 33 and extend to the outer ends of the two slide rails 33 and are fixedly connected to the third gear 39. The two third gears 39 are meshed and connected. The two first screw rods 34 rotate in opposite directions to drive the two moving blocks 35 to move in opposite directions. The top of the moving block 35 is fixedly connected to the fourth hinge plate 37, and the bottom of the sliding sleeve 8 is fixedly connected to the third hinge plate 36. The third hinge plate 36 is hinged to the fourth hinge plate 37.

[0040] The front sides of the two movable sleeves 4 are fixedly connected with reinforcement plates 40, and the two reinforcement plates 40 are respectively fixedly connected to the two sides of the bottom of the bottom plate 5. The bottom of the fixed frame 1 is fixedly connected with a base 44, and the top side of the fixed frame 1 is fixedly connected with a protective box 43 to improve the support effect of the bottom plate 5. The base 44 and the protective box 43 are rotatably connected on both sides.

Motors are installed on both sides of the protective box 43, and the two second screw rods 42 are respectively fixedly connected to the two motor output ends, which is conducive to adjusting the height of the bottom plate 5.

[0041] When the present invention is in use, the motors on both sides of the protective box 43 are started to drive the two second screw rods 42 to rotate, thereby causing the second screw rod 42 to rotate and drive the movable sleeve 4 to rise, thereby causing the two movable sleeves 4 to drive the bottom plate 5 to rise, and when the bottom plate 5 rises, it drives the support rod 6 to rise, thereby causing the two support rods 6 to drive the material receiving plate 7 to rise, thereby causing the material receiving plate 7 to rise to the inside of the bracket 3, and the material is transported and moved to the top of the bracket 3 by the conveyor belt body 2, thereby causing the material to fall on the top of the material receiving plate 7, and the front side of the bracket 3 is provided with a support wheel 45, which blocks the material by the support wheel 45 to prevent the material from rushing out of the limited position due to excessive inertia, and the material presses down the material receiving plate 7, causing the material receiving plate 7 to deflect with the hinge point of the material receiving plate 7 and the support rod 6 as the rotation axis, and then The receiving plate 7 drives the connecting plate 31 to descend, and the connecting plate 31 drives the first hinged plate 28 to descend, and the first hinged plate 28 drives the protective box 24 to descend the sleeve 10, so that the sleeve 10 drives the piston plate 9 to slide inside the sliding sleeve 8, so that the piston plate 9 drives the support sleeve 11 to descend, so that the buffer inside the sliding sleeve 8 flows from the piston plate 9 and the support sleeve 11 to form a damping effect, and the protective box 24 presses the second spring 29 when descending, and cooperates with the damping effect to buffer the connecting plate 31, thereby supporting and buffering the receiving plate 7, which is beneficial to supporting the material, facilitating the unloading of the material, and improving the stability of the material when it is transferred to the subsequent workstation. When the receiving plate 7 is deflected, the connecting plate 31 drives the slider 30 to slide on the outside of the support plate 46 to prevent it from getting stuck.

[0042] The first motor 25 is started to drive the first gear 26 to rotate, and the first gear 26 drives the second gear 27 to rotate, so that when the second gear 27 rotates, it drives the rotating rod 22 to rotate, and when the rotating rod 22 rotates, it drives the rotating plate 20 to rotate. When the rotating plate 20 rotates, the multiple inclined grooves 21 inside it guide the multiple guide rods 19, so that the multiple inclined grooves 21 guide the multiple guide rods 19, and when the multiple guide rods 19 move, they drive the multiple blocking plates 13 to move, so that the multiple blocking plates 13 move toward the outside of the through hole 12, and when the blocking plate 13 moves, it drives the movable block 14 to move, so that the blocking plate 13 drives the movable block 14 to move inside the through hole 12 to the wide When the first and second movable blocks 14 are in the same position, the first spring 15 pushes the two movable blocks 14 to move to both sides and makes the movable blocks 14 fit with the inner wall of the through hole 12. When the multiple blocking plates 13 drive the multiple movable blocks 14 to open outward, the multiple through slots inside the piston plate 9 are blocked, so that the size of the flow openings of the multiple through slots is changed, thereby changing the resistance of the buffer solution when it passes through, thereby adjusting the overall damping effect to prevent the material from being too light to push the receiving plate 7 to deflect, and the damping effect being too large to slow down the unloading speed. At the same time, it prevents the material from being too heavy and the damping force is insufficient, thereby reducing the buffering effect on the material. This is conducive to adjusting the buffering force according to materials of different weights, and facilitating unloading.

[0043] The first screw rod 34 is driven to rotate by the second motor 38, and the two first screw rods 34 are driven to rotate in the opposite direction through the third gear 39, thereby driving the two moving blocks 35 to move in the opposite direction. The two moving blocks 35 drive the bottoms of the two sliding sleeves 8 to move in the opposite direction, and the angles of the two sliding sleeves 8 are adjusted, so that the connecting plate 31 drives the receiving plate 7 to deflect, which is conducive to adjusting the initial angle of the receiving plate 7 to adapt to different materials.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
