[0001] This application relates to the field of sorting devices, and particularly to a sorting and conveying device for cardboard. Background Art
[0002] With the development of automation technology and the concept of intelligent manufacturing, the requirements for product quality control in modern industry are increasing day by day. During the cardboard production process, due to differences in raw materials, printing, or die-cutting processes, cardboard often has defective problems such as size deviation, surface contamination, and edge damage.
[0003] To ensure the quality consistency of the final product, it is necessary to effectively separate cardboard of different specifications or states (such as size deviation, surface defects, etc.) through sorting. Existing sorting often uses manual operation or simple robotic arm grasping methods on the cardboard conveyor line. Cardboards of various specifications are usually mixed on the conveyor line, resulting in low efficiency and low recognition rate of minor defects, and prone to misjudgment. Summary of the Invention

One end of the first starting drive is hinged to the bracket, and the other end is hinged to the first sorting frame. There is an included angle between the first starting drive and the bracket. The first starting drive is used to drive one end of the first sorting frame away from the bracket, so that a sorting opening is formed between the first sorting frame, the first sorting roller, and the plurality of conveying rollers of the first conveying component. The sorting opening is used for dropping defective products.
[0006] By adopting the above technical solutions, when the cardboard is conveyed by the first conveying component, the detection member detects the cardboard. When a defective product is detected, the first starting drive is started. The first starting drive drives the first sorting frame to rotate, lowers the first sorting roller. The cardboard falls from the sorting opening through the first sorting roller onto the second conveying component. The second conveying component recovers and sorts the defective products, facilitating the sorting of defective products of cardboard of different specifications.

The recycling conveyor is used to convey defective cardboard. The second detection is arranged between multiple first sorting components, away from the first sorting component and the second sorting component, and is used to detect the specifications of the cardboard. The sorting conveyor is used to convey cardboard of different specifications.
[0014] By adopting the above technical solution, the recycling conveyor recycles defective cardboard, the sorting conveyor sorts and conveys cardboard of different specifications, the first detection component detects defective cardboard, and the second detection sorts the specifications of the cardboard after screening out defective products, improving the qualification rate of the sorted cardboard.
[0015] Optionally, a receiving component is arranged below each of the first sorting components. The receiving component is used to receive the cardboard falling from the sorting opening and transfer the cardboard to the second conveying component.
[0016] By adopting the above technical solution, the receiving component receives the cardboard and then drops it onto the second conveying component, reducing the possibility of the cardboard stacking on the second conveying component when it falls.
[0017] Optionally, the receiving component includes a receiving plate, a support plate, a lifting drive, and a second baffle.
