[0005] To solve the above problems, the weighing and sorting system involved in this utility model adopts the following technical solution: This utility model provides a weighing and sorting system, including a weighing conveyor, a first conveyor, a second conveyor, a third conveyor, and a sorting device. The weighing conveyor is located in front of the first conveyor, and materials can be weighed by the weighing conveyor and then transported to the first conveyor. The second and third conveyors are respectively located on the left and right sides of the first conveyor. The sorting device includes a workbench located above the first conveyor, a guiding mechanism and a sorting mechanism located on the workbench. The guiding mechanism guides the movement trajectory of the materials on the first conveyor and can push the materials to the second or third conveyor in cooperation with the sorting mechanism.

[0006] Preferably, the guiding mechanism includes a first cylinder, a second cylinder, a baffle, a mounting plate, and a guiding assembly. Both the first and second cylinders are fixed on the worktable. The telescopic end of the first cylinder is connected to the mounting plate. The guiding assembly is mounted on the mounting plate. The telescopic end of the second cylinder is connected to the baffle. The guiding assembly is configured as a guiding channel composed of two spaced and symmetrically arranged baffles. The guiding channel includes a uniform width section with equal width along its length and a narrowing guide section with gradually decreasing width. The narrow opening of the guide section is connected to the uniform width section. The guiding direction of the guiding assembly is the same as the conveying direction of the first conveyor. The baffle is perpendicular to the conveying direction of the first conveyor and is located at the guiding outlet of the guiding assembly. The second cylinder operates to drive the baffle to move vertically towards or away from the second conveyor.

[0007] Preferably, the sorting mechanism includes a third cylinder and a fourth cylinder installed on the lower wall of the workbench. The third cylinder and the fourth cylinder are respectively located on the side of the first conveyor closer to the second conveyor and the side of the third conveyor.

[0008] The beneficial effects of this utility model are as follows: This utility model provides a weighing and sorting system. By setting up a weighing conveyor, the weight of the material is first detected and then transported to the first conveyor. In conjunction with the guiding mechanism and sorting mechanism above the workbench, the orderly guidance and precise sorting of the material are realized. The guiding channel composed of two baffles can effectively regulate the movement trajectory of the material. The narrowing design of the guiding section can gradually straighten the material and maintain a stable conveying posture after entering the equal width section. The baffle moves vertically under the drive of the second cylinder. It can not only block the material when it reaches the designated position to ensure accurate sorting, but also move away when it needs to be released without affecting the material conveying. This realizes the classified conveying of different types of materials. Attached Figure Description

[0011] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] This utility model provides a weighing and sorting system, as shown in the figure, including a weighing conveyor 1, a first conveyor 2, a second conveyor 3, a third conveyor 4, and a sorting device. The weighing conveyor 1 is located on the feeding side of the first conveyor 2 in the conveying direction. The material can be weighed by the weighing conveyor 1 and then conveyed to the first conveyor 2. The second conveyor 3 and the third conveyor 4 are located on both sides of the first conveyor 2 in the conveying direction and are adjacent to the first conveyor 2. The sorting device includes a workbench 8 located above the first conveyor 2, a guiding mechanism located on the workbench 8 and between the workbench 8 and the first conveyor 2, and a sorting mechanism. The guiding mechanism guides the movement trajectory of the material on the first conveyor 2, and the sorting mechanism pushes the material from the first conveyor 2 to the second conveyor 3 or the third conveyor 4 through physical contact. The weighing conveyor 1, the first conveyor 2, the second conveyor 3, and the third conveyor 4 are all existing technologies in the field. This application only combines them and adds a sorting device to solve the problems existing in the prior art without changing the structure of the above devices.

[0013] The guiding mechanism includes a first cylinder 9, a second cylinder 10, a baffle, a mounting plate 11, and a guiding component 5. Both the first cylinder 9 and the second cylinder 10 are fixed on the worktable 8. The telescopic end of the first cylinder 9 is connected to the mounting plate 11. The guiding component 5 is installed on the mounting plate 11, which is parallel to the first conveyor 2. The guiding component 5 is perpendicular to the mounting plate 11. The guiding component 5 is configured as a guiding channel composed of two spaced and symmetrically arranged baffles. The guiding channel includes a section of equal width with equal width along its length and a guide section with gradually decreasing width in a constricted shape. The narrow opening of the guide section is connected to the equal width section. The guiding direction of the guiding component 5 is the same as the conveying direction of the first conveyor 2. The telescopic end of the second cylinder 10 is connected to the baffle, which is perpendicular to the conveying direction of the first conveyor 2. The baffle is located at the guiding outlet of the guiding component 5. The second cylinder 10 works to drive the baffle to move vertically towards or away from the second conveyor 3 and can block the guiding outlet of the guiding channel.

[0014] The material on the weighing conveyor 1 is first guided by the guide section and then enters the equal width section. If the material weight is qualified, the material continues to be conveyed along the first conveyor 2. If the material is not qualified, the second cylinder 10 works to block the material from continuing to be conveyed along the first conveyor 2 by lowering the baffle. At the same time, the first cylinder 9 works to release the obstruction on the left and right sides of the material by raising the guide component 5.

[0015] The sorting mechanism includes a third cylinder 6 and a fourth cylinder 7 mounted on the lower wall of the workbench 8. The third cylinder 6 and the fourth cylinder 7 are respectively located on the side of the first conveyor 2 closest to the second conveyor 3 and the side of the third conveyor 4. The extension and retraction directions of the third cylinder 6 and the fourth cylinder 7 are the same as the conveying direction of the second conveyor 3. Push plates are mounted on the extension and retraction ends of the third cylinder 6 and the fourth cylinder 7. The stroke of the push plate driven by the third cylinder 6 (fourth cylinder 7) is at least outside the guide assembly 5, so that the third cylinder 6 (fourth cylinder 7) does not interfere with the conveying of materials on the first conveyor 2. At the same time, the stroke of the push plate driven by the third cylinder 6 (fourth cylinder 7) can abut against the box below the workbench 8 and continue to push it forward onto the second conveyor 3 (third conveyor 4).

[0016] Furthermore, the worktable 8 is positioned above the first conveyor 2 by being fixed to a mounting bracket spanning the first conveyor 2. The push plates on the third cylinder 6 and the fourth cylinder 7 are staggered to prevent motion interference.

[0017] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
