[0034] Please refer to Figures 1-8 As shown in the drawings, the bagged product rejection mechanism comprises a rack 1, the rack 1 is Z-shaped at both sides, a plurality of supporting legs 2 are fixedly connected to the bottom of the rack 1, and a detection plate 3 is fixedly connected to the inner wall of the rack 1, a weighing sensor 4 is installed at the bottom of the detection plate 3, the weighing sensor 4 is an existing product available on the market, the weighing accuracy of which can reach ±0.1g, a feeding mechanism is installed in the rack 1, a rejection mechanism is installed on one side of the rack 1, a supporting plate 5 is fixedly connected to the outer wall of the other side of the rack 1, a recycling groove 6 is placed on the supporting plate 5, a discharge port 7 is formed in the top surface of the side of the rack 1 close to the supporting plate 5, and the defective products rejected can fall into the recycling groove 6 along the discharge port 7, so that the defective products can be uniformly recycled through the recycling groove 6, and a compaction mechanism is arranged above the discharge port 7;

[0035] The feeding mechanism comprises a motor 8 and a driven roller 9, the motor 8 is installed at one end of the outer wall of the rack 1, the output shaft of the motor 8 penetrates the side wall of the rack 1 and is fixedly connected with a driving roller 10, the driven roller 9 is located in the other end of the inner wall of the rack 1, a through hole is formed in the center of the driven roller 9, a roller shaft 11 is inserted into the through hole, the two ends of the roller shaft 11 are both installed on the two sides of the rack 1 through bearings, the height of the driving roller 10 is flush with that of the driven roller 9, and a feeding belt 12 is transmissionally connected between the driving roller 10 and the driven roller 9, the driving roller 10 can be rotated by driving the motor 8, and the feeding belt 12 and the driven roller 9 can be rotated together when the driving roller 10 rotates, so as to convey the bagged products;

[0036] The rejection mechanism comprises a first electric telescopic rod 13, which is installed on the outer wall of the rack 1 away from the supporting plate 5, and the output shaft of the first electric telescopic rod 13 is fixedly connected with a blowing bin 14, the top of the blowing bin 14 is installed with an industrial camera 15, the industrial camera 15 is a commercially available product, the inside of the blowing bin 14 is installed with a fan 16, the front end face of the blowing bin 14 is installed with a push plate 17, the center of the push plate 17 is provided with a blowing port 18, the blowing port 18 is connected with the inner cavity of the blowing bin 14, and the side wall of the blowing bin 14 can be provided with an opening. The weighing sensor 4 and the industrial camera 15 are electrically connected with the first electric telescopic rod 13 and the fan 16 respectively through wires. When the bagged product moves along with the feeding belt 12 to pass through the industrial camera 15, the surface of the bagged product can be shot by the industrial camera 15, and the shot image information is remotely transmitted to the computer. The image processing software in the computer can analyze and compare the standard template to detect whether the surface of the bagged product has defects (such as packaging damage, label error, etc.). Once the defective product is detected, the industrial camera 15 can send a rejection signal through the wire and drive the fan 16 to blow. At this time, the product with surface defects can be blown away from the feeding belt 12 by the pneumatic blowing mode, so as to complete the rejection of the bagged product. At the same time, the weighing sensor 4 at the bottom of the detection plate 3 can dynamically weigh the bagged product on the feeding belt 12 and compare it with the preset weight range.

In addition, when the weighing sensor 4 detects that the weight of the bagged product exceeds the maximum preset value, a rejection signal can be sent through the wire and the first electric telescopic rod 13 is driven to move the push plate 17. At this time, the defective product with heavy weight can be pushed away from the feeding belt 12 by the push plate 17, which not only effectively meets the rejection requirement of different types of defective products, but also avoids incomplete rejection of defective products remaining on the feeding belt 12.

[0037] The compaction mechanism comprises a fixed plate 19, which is fixedly connected to the inner wall of the rack 1 near the supporting plate 5, and the top of the fixed plate 19 is installed with a second electric telescopic rod 20, and the bottom end of the output shaft of the second electric telescopic rod 20 is fixedly connected with a pressing plate 21. When the defective products are uniformly collected through the recovery groove 6, the second electric telescopic rod 20 can be driven to move the pressing plate 21 downward. At this time, the defective products collected in the recovery groove 6 can be compacted by the pressing plate 21, so as to expand the internal space of the recovery groove 6 and store more defective products without frequent replacement.

[0038] The top surface of the detection plate 3 is flush with the top surface of the rack 1 and is attached to the lower top surface of the feeding belt 12.
