The reject cylinder drives a push plate. After the materials pass through the conveyor belt and the weighing conveyor belt in sequence, the reject cylinder drives the push plate to push the unqualified weight products into the collection box, and the qualified weight products continue to move along the reject conveyor belt and fall from the reject conveyor belt relative to one end of the weighing conveyor belt. However, in the above structure, the qualified weight materials fall directly at the end of the reject conveyor belt. The materials have a high speed and have a large impact force when falling to the collection device below, which will damage the materials. In addition, the direct falling method makes the material falling position inaccurate, which can easily lead to the problem of scattered materials and uneven stacking. Summary of the Invention

[0004] A conveyor belt for a checkweigher is provided. A downwardly inclined section with an adjustable angle is provided at the end of the conveyor belt, so that the material is tilted and displaced before falling, which slows down the falling speed, reduces the impact force, and falls into the collection device more accurately, reducing the scattering and uneven accumulation of materials.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a conveyor belt of a checkweigher, comprising a first conveying bracket, an active roller that rotates actively is provided at one end of the first conveying bracket, and the characteristics are: the first conveying bracket is provided with a second conveying bracket that is inclined and can adjust the inclination angle relative to one end of the active roller, the second conveying bracket is provided with a first driven roller at one end relative to the first conveying bracket, a conveyor belt is connected between the active roller and the first driven roller, the first conveying bracket is provided with a second driven roller and a third driven roller that are longitudinally parallel at one end relative to the active roller, a passing gap is provided between the second driven roller and the third driven roller for the conveyor belt to pass through, the part of the conveyor belt that rotates to the lower side always passes through the passing gap, and the second conveying bracket is provided with an adjustment support device that drives it to adjust the angle.

[0006] A further configuration of the present invention is that one end of the second conveying bracket opposite to the first driven roller is hingedly connected to one end of the first conveying bracket opposite to the active roller.

[0007] The utility model is further configured as follows: the first conveying bracket includes first conveying bracket side plates that are relatively arranged, the active roller is rotatably arranged at one end of the same side of the two first conveying bracket side plates, the second driven roller and the third driven roller are longitudinally arranged in parallel between the two first conveying bracket side plates at one end relative to the active roller, the second conveying bracket includes second conveying bracket side plates that are relatively arranged, each of the first conveying bracket side plates is provided with a mounting groove at one end relative to the active roller, each of the second conveying bracket side plates is provided in a corresponding mounting groove at one end relative to the first driven roller and is hingedly connected to the mounting groove, and a downwardly inclined limiting surface is provided on one side below the mounting groove.

[0008] A further configuration of the present invention is: the adjusting support device includes a driving device, any second conveying bracket side panel is provided with a hinged seat, the output end of the driving device is hingedly connected to the hinged seat, the driving device is connected with a connecting rod, and the connecting rod is fixedly connected to the first conveying bracket side panel provided on the same side of the second conveying bracket side panel provided with the hinged seat.

[0009] The utility model with the above-mentioned characteristics: the second conveying bracket is hingedly connected to the first conveying bracket, so that the second conveying bracket can be tilted downward, the driving device controls the angle adjustment of the second conveying bracket to adapt to materials of different sizes and weights, and the part of the conveyor belt rotated to the lower side always passes through the gap, preventing the conveyor belt from loosening and falling due to the angle adjustment of the second conveying bracket.

[0010] The beneficial effect of the utility model is that a downwardly inclined section with an adjustable angle is provided at the end of the conveyor belt, so that the material is tilted and displaced before falling, which slows down the falling speed, reduces the impact force, and falls into the collection device more accurately, reducing the scattering and uneven accumulation of materials.
