[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a weight re-inspection device for detecting bagged finished products includes a weighing device 1, a bracket 3 is arranged on the top of the weighing device 1, an active roller 23 is rotatably connected inside the bracket 3, a driven roller 22 is rotatably connected inside the bracket 3, a conveyor belt 6 is arranged on the outer sides of the active roller 23 and the driven roller 22, a fixed plate 2 is fixedly connected to one side of the bracket 3, a driving assembly is arranged on the top of the fixed plate 2, a slide plate 5 is fixedly connected to one side of the bracket 3, a collecting box 4 is arranged on one side of the bracket 3, a mounting plate 14 is fixedly connected to one side of the bracket 3, and a rejection assembly is arranged on the top of the mounting plate 14.

[0022] First, the product is placed on the top of the conveyor belt 6 through the bag dumper, and then the driving component is started to drive the active roller 23 to rotate while driving the driven roller 22 and the conveyor belt 6 to rotate. The driving component can provide a larger output torque, so that the conveyor belt 6 can smoothly transport items with heavy weight or large resistance, thereby enhancing the transmission capacity of the conveyor belt 6, and can achieve higher transmission efficiency, reduce energy consumption, and reduce production costs. Then, when the product moves on the conveyor belt 6, the weighing device 1 can detect the weight of the product in real time. If the weight does not meet the preset weight, the rejection component will be started to operate so that the unqualified product will be rejected from the conveyor belt 6. This can avoid the situation where the packer regularly uses the re-inspection scale, takes it down from the belt conveyor, performs manual calibration, and then finds a ledger to record it manually in sequence. According to the weighing results of the re-inspection scale, the accuracy of the quantitative packaging scale is determined to meet the requirements of the weight of the finished packaged material. Due to manual detection, there will be untimeliness, resulting in inaccurate measurement, affecting the quality of the product out of the warehouse, thereby increasing the practicality of the device. The rejected products fall into the interior of the collection box 4 through the slide plate 5 for subsequent processing.

[0023] like Figure 1-Figure 4As shown, the rejection component includes a fixed frame 10, which is fixedly connected to the top of the mounting plate 14, and four guide wheels 9 are fixedly installed equidistantly inside the fixed frame 10. A displacement rod 11 is slidably connected inside the fixed frame 10, and the outer side of the displacement rod 11 contacts the outer side of the guide wheel 9. The rejection component also includes a push plate 7, which is fixedly connected to one end of the displacement rod 11. A cylinder 8 is fixedly installed on the top of the mounting plate 14, and one end of the movable rod of the cylinder 8 is fixedly connected to one side of the push plate 7. A limiting groove 13 is provided on the outer side of the fixed frame 10, and a limiting block 12 is slidably connected inside the limiting groove 13, and one end of the limiting block 12 is fixedly connected to one side of the displacement rod 11.

[0024] When rejecting, the movable rod of the cylinder 8 is started to move, driving the push plate 7 to move and driving the displacement rod 11 to move at the same time. Then, when the displacement rod 11 moves, the guide wheels 9 arranged above and below it can make it move more smoothly. Then, the displacement rod 11 moves to drive the limit block 12 to slide inside the limit groove 13, thereby limiting the moving distance of the displacement rod 11. Then, the push plate 7 moves to push the product and make it detach from the conveyor belt 6.

[0025] like Figure 1-Figure 4 As shown, the driving assembly includes a motor 21, which is fixedly installed on the top of the fixed plate 2. Two vertical plates 16 are fixedly connected to the top of the fixed plate 2, one side of one of the vertical plates 16 is rotatably connected to a large pulley 17, one end of the output shaft of the motor 21 is fixedly connected to a small pulley 20, and a V-belt 18 is provided on the outer side of the small pulley 20 and the large pulley 17. The driving assembly also includes a pinion 19, which is rotatably connected between the two vertical plates 16, one end of the rotating shaft of the pinion 19 is fixedly connected to one end of the rotating shaft of the large pulley 17, a large gear 15 is rotatably connected between the two vertical plates 16, the large gear 15 is meshed with the pinion 19, and one end of the rotating shaft of the large gear 15 is fixedly connected to one end of the rotating shaft of the active roller 23.

[0026] During transportation, the output shaft of the starting motor 21 rotates to drive the small pulley 20 to rotate and the V-belt 18 to move, and then drives the large pulley 17 to rotate, so that the speed matching between the small pulley 20 and the large pulley 17 can be achieved, ensuring that the large pulley 17 runs at a suitable speed, and then the large pulley 17 rotates to drive the small gear 19 to rotate and the large gear 15 to rotate, and then the large gear 15 rotates to drive the active roller 23 to rotate, so that the conveyor belt 6 can move more smoothly.

[0027] The utility model provides a weight re-inspection device for detecting bagged finished products. The specific working principle is as follows: first, the product is placed on the top of the conveyor belt 6 through the bag dumper, and then the output shaft of the motor 21 is started to rotate to drive the small pulley 20 to rotate and drive the V-belt 18 to move, and then drive the large pulley 17 to rotate, so that the speed matching between the small pulley 20 and the large pulley 17 can be achieved, ensuring that the large pulley 17 runs at a suitable speed, and then the large pulley 17 rotates to drive the small gear 19 to rotate and drive the large gear 15 to rotate, and then the large gear 15 rotates to drive the active roller 23 to rotate, so that the conveyor belt 6 can move more smoothly, and then, When the product moves on the conveyor belt 6, the weight of the product can be detected in real time through the weighing device 1. If the weight does not meet the preset weight, the movable rod of the cylinder 8 will be started to move, driving the push plate 7 to move and driving the displacement rod 11 to move at the same time. Then, when the displacement rod 11 moves, the guide wheels 9 arranged above and below it can make it move more smoothly. Then, the displacement rod 11 moves to drive the limit block 12 to slide inside the limit groove 13, thereby limiting the moving distance of the displacement rod 11. Then, the push plate 7 moves to push the product to make it detach from the conveyor belt 6. Finally, the rejected product falls into the interior of the collection box 4 through the slide plate 5 for subsequent processing.
