[0018] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0019] like Figure 1-4As shown, a multi-stage weight sorting machine comprises a frame 1, on which a servo motor 2 is fixedly mounted, the output shaft of the servo motor passes through the frame and a turntable 3 is fixed upward, and connecting seats 4 are evenly fixed around the circumference of the turntable, and a sorting bucket 5 is fixed on the connecting seat;

[0020] The upper end of the sorting bucket is open, and an opening and closing structure is installed at the lower end of the sorting bucket. The lower end of the turntable is evenly distributed circumferentially with guide tubes 6 with the same number as the sorting buckets, and a guide structure is arranged inside the guide tubes.

[0021] In this way, the product is weighed by the weighing belt conveyor. After weighing, the signal is transmitted to the servo motor, and the servo motor drives the turntable to rotate the corresponding angle, so that the corresponding number of sorting buckets are placed exactly opposite the weighing belt conveyor. The product is transported by the weighing belt conveyor and reaches the sorting bucket. After the sorting bucket rotates to the corresponding guide cylinder, the opening and closing structure opens, and the product falls into the guide cylinder after passing through the opening and closing structure, and is guided to the storage basket through the guide cylinder to complete the sorting. The frame and the guide cylinder are placed on the support table, and the storage basket is set below the support table to facilitate the product to enter the storage basket.

[0022] During implementation, the opening and closing structure is fixedly mounted on the opening and closing cylinder 7 at the lower end of the sorting bucket, the two ends of the opening and closing cylinder are penetrated, an opening and closing roller 8 is rotatably arranged in the opening and closing cylinder, the opening and closing roller is penetrated with a drop hole 9, the two ends of the opening and closing roller are connected to the opening and closing cylinder through bearings, one end of the opening and closing roller passes through the opening and closing cylinder and is fixedly connected to the output shaft of the opening and closing motor 10, and the opening and closing motor is connected to the outside with a power line. The servo motor drives the opening and closing roller to rotate, and when the drop hole is facing the upper and lower ends of the opening and closing cylinder, the product falls; when the drop hole is misaligned with the upper and lower ends of the opening and closing cylinder, the product is located in the opening and closing cylinder, which is convenient for improving efficiency.

[0023] Specifically, a power supply is fixed on the outside of the sorting cylinder, and the servo motor is connected to the power supply. The power supply is a lithium battery. Of course, the servo motor can be connected to the mains to drive the turntable to rotate within the range of 360 degrees forward and 360 degrees reverse.

[0024] During implementation, the flow guiding structure includes a flow guiding block 11 fixedly installed in the flow guiding tube, the upper end of the flow guiding tube is open, a discharge port is arranged on one side of the lower end of the flow guiding tube, and the flow guiding block has a flow guiding slope, which is arranged opposite to the discharge port. The setting of the flow guiding block facilitates the product to quickly reach the storage basket.

[0025] During implementation, a material blocking member 12 is fixed to the upper end of the sorting bucket, and the outer side and the upper side of the material blocking member are both opened, so as to block the products conveyed by the weighing belt conveyor and prevent them from reaching the turntable due to inertia.

[0026] During implementation, a reinforcement arm 13 is also fixed between the rotating disk and the sorting bucket to improve strength.

[0027] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
