[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figure 1 - Figure 2 , the present utility model provides a technical solution: an embodiment includes a frame 10, a feeding channel, a weighing channel, a blanking channel, a first discharge channel 4 and a second discharge channel 5. The feeding channel, the weighing channel and the blanking channel are communicatively connected.

[0018] The feeding channel includes a plurality of feeding tracks 11 and a conveying frame 12. The feeding tracks 11 convey products through feeding belts. A plurality of feeding belts are rotationally limited on the conveying frame 12. A conveying partition is provided between adjacent feeding tracks. The conveying partition is used to partition adjacent feeding belts to ensure that each feeding belt can convey independently. The feeding tracks 11 are inclined. Transverse sections for supporting the products to rise are evenly distributed on the feeding belts. All the feeding belts are synchronously rotated by the same motor and the same synchronous shaft.

[0019] The weighing channel includes weighing belt scales 21 corresponding to the number of the material conveying tracks 11 and weighing partitions. The weighing belt scales 21 are arranged below the higher ends of the material conveying tracks 11, and the weighing belt scales 21 are correspondingly arranged in front of the material conveying tracks. The weighing partitions are arranged between adjacent weighing belt scales 21, so that the weighing belt scales 21 rotate synchronously, and the weighing belt scales 21 are horizontally placed. The feeding ports and discharging ports of the weighing belt scales 21 are both arranged at one end close to the material conveying channel, in order to save the floor area of the equipment and make the overall equipment more compact. The material conveying track 11 conveys products to the weighing channel, and the products fall onto the weighing channel after leaving the material conveying track 11.

[0020] The blanking channel includes blanking tracks 31 corresponding to the number of the material conveying tracks 11. The blanking tracks 31 are arranged below the material conveying tracks 11, and the blanking tracks 31 are inclined. The higher ends of the blanking tracks 31 are at the same height as and communicate with the weighing belt scales 21. One end of the blanking track 31 far from the weighing belt scale 21 is rotationally connected to the frame 10 in a limited way. The blanking track 31 is provided with a blanking air cylinder 32 for driving the blanking track 31 to rotate. Each single blanking track 31 is independently driven by a single blanking air cylinder 32. The fixed end of the blanking air cylinder 32 is rotationally connected to the frame 10 in a limited way, and the output end is rotationally connected to the blanking track 31 in a limited way. The blanking air cylinder 32 drives the blanking track 31 to rotate so that the higher end of the blanking track 31 is higher than or flush with the discharging port of the weighing belt scale 21, and the blanking track 31 communicates with the weighing belt scale 21.

[0021] The first discharging channel 4, the second discharging channel 5 and the weighing channel are arranged in a step shape. The second discharging channel 5 is arranged below the blanking channel. The lower end of the blanking track 31 is arranged above the first discharging channel 4. The first discharging channel 4 and the second discharging channel 5 convey products through a belt, and the conveying directions of the first discharging channel 4 and the second discharging channel 5 are inconsistent with the conveying direction of the weighing belt scale 21. The weighing belt scale 21 conveys products. After the products leave the weighing belt scale 21, they can directly fall into the second discharging channel 5 or enter the blanking track 31. The products on the blanking track 31 slide into the first discharging channel 4 due to gravity.

[0022] The working principle and usage process of the present utility model: The material conveying channel conveys products to the weighing belt scale 21. The weighing belt scale 21 weighs the products. After weighing, the weighing belt scale 21 outputs all the products at the same time. Each single blanking track 31 knows the weight of the products according to the feedback of the corresponding weighing belt scale 21, so as to control the output of the blanking air cylinder 32. When the blanking air cylinder 32 outputs, the higher end of the blanking air cylinder 32 rises, and the products fall into the first discharging channel 4. When the blanking air cylinder 32 does not output, the products enter the second discharging channel 5 through the blanking track 31, and finally realize the screening of single products and improve the sorting speed.
