[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Example

[0030] Reference Figure 1-5 As shown, the utility model is a bagged product weighing device, comprising:

[0031] Frame 1;

[0032] The weighing mechanism includes: a weighing element 8 provided on the frame 1, a first support 7 connected to the output end of the weighing element 8, a first conveying trough 17 provided on the first support 7 and used for the bags to be weighed to pass through, and a first conveying assembly for driving the bags to move from the first conveying trough 17 to the output side thereof;

[0033] The sorting mechanism includes: a second support body 4 and a third support body 5 arranged on the output side of the first conveying trough 7, a first telescopic driving member 10 and a second telescopic driving member 11, and a second conveying assembly 14 arranged below the second support body 4. The output ends of the first telescopic driving member 10 and the second telescopic driving member 11 are respectively connected to the second support body 4 and the third support body 5. The second support body 4 is provided with a second conveying trough connected to the first conveying trough 17.

[0034] The utility model discloses a bagged product weighing device, in which the first conveying trough 17 in the first support body 7 is used to place the bag to be weighed, the weighing part 8 resets the first support body 7 and detects the weight of the bag, and judges whether the weight of the bag is qualified by the weighing information, thereby judging whether the bag needs to enter the second conveying assembly 14 or the third conveying assembly 15, and controls the first telescopic driving member 10 and the second telescopic driving member 11 respectively to make the second support body 4 and the third support body 5 move up and down. When the height of the second support body 4 is greater than that of the first support body 7, the bag cannot enter the second support body 4 from the first support body 7, and thus falls onto the second conveying assembly 14. When the height of the second support body 4 is adapted to the first support body 7 and the height of the third support body 5 is greater than that of the second support body 4, the bag passes through the second support body 4 and cannot enter the third support 5, and falls from the output end of the second support body 4 and enters the third conveying assembly 15, thereby completing the automatic sorting of the bag, and realizing automatic weighing and sorting of the bagged products, thereby improving production efficiency and product quality.

[0035] In this embodiment, the second conveying assembly 14 is used to reject bags that are detected as NG and have unqualified weight, and the third conveying assembly is used to convey the remaining bags that have passed the inspection. Generally, NG bags account for a small proportion of the total bags to be inspected. Therefore, the sorting drive source of the second conveying assembly 14 used for conveying NG products is designed to be driven by an independent first telescopic drive member (drive cylinder), which can reduce the number of times the drive cylinder operates, thereby optimizing the operating rhythm, reducing sorting time and reducing usage costs.

[0036] See also Figure 3-Figure 5 As shown, the first conveyor assembly includes: a first conveyor belt 9 that rotates along the length of the first support body 7, multiple push rods 13 connected to the first conveyor belt 9, and a first rotating drive member connected to the output end of the first conveyor belt 9. The first support body 7 is provided with a clearance groove 16. The push rods 13 are no larger than the clearance groove 16. When a bag is to be conveyed, the first rotating drive member is activated, driving the first conveyor belt 9 to rotate. The push rods 13 connected to the conveyor belt 9 move with the movement of the conveyor belt 9. When the push rods 13 contact a bag to be conveyed, they push the bag forward along the first support body 7 within the first conveyor groove 17. As the conveyor belt 9 continues to rotate, the push rods 13 continuously push the bag, gradually moving it from the input end of the first support body 7 to the output end. The push rods 13 navigate within the clearance groove 16 to avoid collision or interference with the first support body 7.

[0037] See also Figure 5 As shown, step surfaces for placing bags are provided on both sides of the avoidance groove 16, and the step surfaces extend along the length direction of the first support body 7. The avoidance groove 16 and the step surfaces are both provided at the bottom of the first conveying groove 17. The width of the avoidance groove 16 is smaller than the width of the bag to be weighed, so that the bag can be supported by the step surface in the first support body 7 and move along the first conveying groove 17.

[0038] There are multiple first support bodies 7 and weighing pieces 8, and the number of second support bodies 4, third support bodies 5 and first telescopic drive members 10 corresponds to the number of first support bodies 7 or weighing pieces 8, so that multiple bags can be weighed independently, and the first telescopic drive member 10 cooperates with the second support body 4 to control whether the bag enters the second conveying assembly 14. The second telescopic drive member 11 can simultaneously control the up and down movement of multiple third support bodies 5, thereby controlling whether the bag enters the third conveying assembly 15.

[0039] See also Figure 4 As shown, the second conveying assembly 14 and the third conveying assembly 15 both include: a second conveying belt 9 rotatably arranged on the frame 1, a second rotating driving member connected to the output end and the second conveying belt 9, and the second conveying belt 9 is driven to rotate in a circular motion by the second rotating driving member, and the first rotating driving member and the second rotating driving member are both driving motors 12.

[0040] The second support body 4 and the third support body 5 are arranged to be tilted downward in sequence, and the height of the second conveying assembly 14 is greater than that of the third conveying assembly 15, so that the bag body slides down along the second support body 4 and the third support body 5. The bag body slides toward the second support body 4 due to its own inertia. The downward tilt of the second support body 4 and the third support body 5 can keep the bag body sufficiently mobile, avoid the bag body from getting stuck in the second support body 4, and improve the weighing and sorting efficiency.

[0041] Baffles are respectively provided below the output sides of the second support body 4 and the third support body 5 to stop and guide the bags under high-speed transmission to prevent the bags from flying out of the support bodies and failing to enter the corresponding conveying components.

[0042] See also Figure 1-Figure 2 As shown, a fourth support body 3 is also provided on the input side of the first support body 7. The fourth support body 3 is provided with a third conveying trough. The third conveying trough is connected to the first conveying trough 17 and is connected to the upstream production line through the fourth support body 3. The bag to be weighed is first placed on the third conveying trough of the fourth support body 3 and then enters the first support body 7.

[0043] The conveying directions of the second conveying assembly 14 and the third conveying assembly 15 are perpendicular to the first conveying direction. The output sides of the second conveying assembly 14 and the third conveying assembly 15 are respectively provided with guides 6 to guide the bags conveyed from the conveying assemblies.

[0044] A cover plate 2 is further provided above the first support body 7. The cover plate 2 is a sealed cover provided above the first support body 7 to prevent dust, debris, etc. from entering the weighing area, and can reduce the impact of airflow on the weighing process, thereby improving the accuracy of the weighing results.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
