The main optional configurations are material metering and filling machines, working platforms, weight sorting scales, material elevators, vibrating feeders, finished product conveying elevators, and metal detectors.

[0003] A Chinese utility model with publication number CN218172735U discloses a bag-feeding packaging machine with a feeding mechanism, which limits the feeding of items by cooperating with each other among structures such as a packaging machine body, a processing box, a conveyor belt, a first motor, a bidirectional screw, a slide groove, a slider, a screw sleeve, a movable block and a baffle to prevent the items from falling, thereby improving the applicability of the equipment.

[0004] When the device is used to unload and convey the packed bags after bagging, the baffle can be used to limit the position of the packed bags in the unloading state. However, since the weight of the packed bags after bagging is different, there is a certain amount of error, and the packed bags with too low or too high weight after bagging cannot be put into the subsequent processing procedures. The device only has the function of limiting the position of the packed bags and conveying, and it is difficult to automatically screen the packed bags in the unloading state. To this end, we provide a unloading structure for bag-feeding packaging machines to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-3 As shown, the utility model provides a technical solution: a feeding structure of a bag-feeding packaging machine, comprising a packaging machine body 1, a feeding component, a weighing device 12, a pushing assembly and two limit assemblies.

[0027] A discharge hopper 2 is provided at the discharge port of the packaging machine body 1 . The packaging machine body 1 is an existing structure, and can complete discharge of materials through the discharge hopper 2 after packaging the materials into the packaging bag.

[0028] The material discharge component comprises a first material discharge component and a second material discharge component, and one end of the first material discharge component is located below the material discharge hopper 2.

[0029] The first unloading assembly includes a first support 3, a first motor 4 installed on the first support 3, a first roller body rotatably connected to the first support 3, and a first conveyor belt 5 arranged in the first support 3. The output shaft of the first motor 4 is equipped with a second roller body, and the second roller body is transmission-connected to the first roller body through the first conveyor belt 5.

[0030] The second roller body is driven to rotate by the output shaft of the first motor 4 , and under the action of the first roller body, the first conveyor belt 5 can convey the finished product packaging bags.

[0031] The weighing device 12 is arranged between the first unloading component and the second unloading component, and is used to weigh the packaging bags conveyed by the first unloading component. The weighing device 12 is an existing structure, which can weigh the packaging bags dropped onto the weighing device 12. In addition, the device also has a control module, which can set a threshold value. After the weighing device 12 weighs the packaging bag, the weighing result is transmitted to the control module for judgment, and then the pushing component can be controlled and driven.

[0032] The second unloading assembly includes a second support 9, a second motor 10 installed on the second support 9, a second conveyor belt 11 arranged in the second support 9, and a third roller body rotatably connected in the second support 9. The output shaft of the second motor 10 is installed with a fourth roller body, and the fourth roller body is transmission-connected to the third roller body through the second conveyor belt 11. The second support 9, the weighing device 12 and the first support 3 are arranged in a stepped manner from bottom to top.

[0033] The output shaft of the second motor 10 drives the fourth roller to rotate, and under the action of the third roller, the second conveyor belt 11 conveys and unloads the good product packaging bags removed from the weighing device 12.

[0034] The pushing assembly includes a fixed seat 13 installed on the weighing device 12, a second electric push rod 16 installed on the fixed seat 13, a second push plate 17 installed on the telescopic end of the second electric push rod 16, a fixed plate 6 installed on the first blanking assembly, a first electric push rod 7 installed on the fixed plate 6, and a first push plate 8 installed on the telescopic end of the first electric push rod 7. The first push plate 8 forms a 90-degree angle with the second push plate 17.

[0035] The telescopic end of the second electric push rod 16 drives the second push plate 17 to move, so that the second push plate 17 can push the defective packaging bags on the weighing device 12 away from the weighing device 12. The telescopic end of the first electric push rod 7 drives the first push plate 8 to move, so that the first push plate 8 can push the good packaging bags on the weighing device 12 onto the second conveyor belt 11.

[0036] A bottom plate 15 is provided below the fixed seat 13 , to which a column 14 is fixedly connected, and the top of the column 14 is fixedly connected to the fixed seat 13 . A defective box 18 is provided on one side of the weighing device 12 , and the defective box 18 can collect the defective packaging bags pushed out by the second push plate 17 .

[0037] The two limit assemblies each include a screw rod 19 , which are respectively fixedly connected to the first support 3 and the second support 9 , a mounting block 20 is inserted into the screw rod 19 , a locking nut 22 is threadedly connected to the screw rod 19 , and a guide plate 21 is fixedly connected to the bottom surface of the mounting block 20 .

[0038] The drainage plate 21 on the mounting block 20 can drain the moving packaging bags on the first conveyor belt 5 and the moving packaging bags on the second conveyor belt 11, so that the packaging bags move to the middle of the first conveyor belt 5 and the middle of the second conveyor belt 11 for transportation.

[0039] Working principle: First, the finished packaging bags on the packaging machine body 1 slide onto the first conveyor belt 5 through the lower hopper 2, then the first motor 4 is started, so that the output shaft of the first motor 4 drives the second roller body to rotate, and under the action of the first roller body, the first conveyor belt 5 can convey the finished packaging bags. Subsequently, the finished packaging bags will fall from the first conveyor belt 5 to the weighing device 12, and the finished packaging bags will be weighed by the weighing device 12 to distinguish good and defective products. When the packaging bags on the weighing device 12 are defective, the telescopic end of the second electric push rod 16 drives the second push plate 17 to move The defective products are pushed from the weighing device 12 to the defective product box 18. When the packaging bag on the weighing device 12 is a good product, the telescopic end of the first electric push rod 7 drives the first push plate 8 to move and pushes the good product to the second conveyor belt 11. Finally, the second motor 10 is started, so that the output shaft of the second motor 10 drives the fourth roller body to rotate, and under the action of the third roller body, the second conveyor belt 11 transports and discharges the good packaging bags removed from the weighing device 12. Weighing and screening can be performed during the unloading process of the finished packaging bags, so that the finished packaging bags put into the next process do not contain defective products.
