[0031] The detection component 102 includes a fixing frame 102a, an operating panel 102b rotatably mounted on the inner wall of the fixing frame 102a, a support plate 102c fixedly mounted on the side surface of the fixing frame 102a, a display 102d adapted to be mounted on the side wall of the support plate 102c, a connector 102e used in conjunction with the display 102d, and a detection component 102f snapped onto the bottom of the connector 102e.
[0032] Specifically, after the equipment is started, the paper cups to be sorted first enter the detection component 102 area, and the operation panel 102b drives the detection component 102f to accurately scan the tea content and distribution in the paper cups. The detection data is displayed in real time on the display 102d; after the detection is completed, the sorting component 103 classifies the paper cups according to the detection results through the flexible contact component 103b.

[0037] During use, the detection component 102 drives the detection head 102f-1 to scan the paper cups in transit at multiple angles through the adjustable connector 102e. The elastic connection structure ensures detection stability; the sorting component 103 automatically classifies according to the detection data, and the flexible contact mechanism realizes non-destructive sorting; qualified products are transported to the storage box 105 through the unloading component 104, and unqualified products enter the waste collection system after re-inspection on the second inspection table 106; adopting a mechatronics design, the elastic snap-fit and angle adjustment functions of the connector 102e ensure detection accuracy, the buffer device of the sorting mechanism avoids product damage, and the automatic conveying system ensures continuous operation, realizing automated intelligent control of the entire process from detection, sorting to classified packaging, significantly improving sorting efficiency and accuracy.
[0038] In summary, the detection component 102 adopts an elastic connection structure and a multi-angle adjustment mechanism to ensure detection accuracy and stability. The sorting component 103 realizes non-destructive sorting through the flexible contact component 103b. The unloading component 104 is equipped with an automatic sorting mechanism to improve sorting efficiency. The waste collection system realizes automatic separation of unqualified products. It is easy to operate, improves sorting accuracy and production efficiency, and reduces manual intervention and false detection rate.
[0039] Example 2
[0040] Reference Figure 4-5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that when inspecting items, the sorting quality and efficiency can be improved by the sorting component 103.
[0041] The sorting assembly 103 includes a measuring plate 103a, a contact component 103b fixedly connected to the surface of the measuring plate 103a, and a placement groove 103c provided on the surface of the contact component 103b.
[0042] The contact component 103b includes a contact plate 103b-1, a telescopic column 103b-2 fixedly connected to the inner cavity of the contact plate 103b-1, a telescopic cylinder 103b-3 sleeved on the end of the telescopic column 103b-2, a rotating rod 103b-5 hinged on the side surface of the contact plate 103b-1, and a connecting rod 103b-6 fixedly installed in the inner cavity of the contact plate 103b-1.
[0043] The contact component 103b also includes a connecting spring 103b-7 sleeved on the outer surface of the connecting rod 103b-6, a sliding sleeve 103b-8 fixedly connected to the end of the connecting spring 103b-7, and a buffer spring 103b-9 fixedly connected to the inner cavity of the contact plate 103b-1.
[0044] The unloading assembly 104 includes an operating box 104a, a protective door 104b hinged on the side surface of the operating box 104a, a connecting plate 104c fixedly connected to the end of the operating box 104a, a unloading trough 104d opened on the surface of the connecting plate 104c, a unloading roller 104e rotatably installed in the center of the unloading trough 104d, and a unloading plate 104f fixedly connected to the side surface of the connecting plate 104c.
[0045] The waste collection assembly 107 includes an operating table 107a, a quality inspection plate 107b fixedly connected to the surface of the operating table 107a, a quality inspection roller 107c rotatably installed on the surface of the quality inspection plate 107b, a baffle 107d fixedly connected to the side wall of the quality inspection plate 107b, and a waste box 107e placed under the baffle 107d.
[0046] During use, the contact part 103b of the sorting component 103 achieves flexible contact detection through the coordinated action of the telescopic column 103b-2 and the buffer spring 103b-9. When the paper cup enters the placement slot 103c, the connecting spring 103b-7 and the sliding sleeve 103b-8 mechanism provide adaptive pressure to ensure stable clamping; the measuring plate 103a collects data in real time and transmits it to the control system for classification decision-making; qualified products are smoothly transported to the next process via the unloading roller 104e of the unloading component 104, and unqualified products are guided to the waste bin 107e via the quality inspection roller 107c; the entire sorting process adopts a multi-stage buffer design, the rotating rod 103b-5 and telescopic cylinder 103b-3 structure realize non-destructive operation, and the protective door 104b and baffle 107d ensure operational safety.
[0047] In summary, the sorting component 103 adopts a multi-level buffer mechanism to ensure lossless sorting. The synergistic effect of the telescopic column 103b-2 and the connecting spring 103b-7 provides a stable clamping force, and the buffer spring 103b-9 effectively absorbs impact to protect the product. The unloading component 104 is equipped with an adjustable unloading roller 104e to achieve smooth transportation, and the protective door 104b ensures safe operation. The waste collection system achieves precise separation through the cooperation of the quality inspection roller 107c and the baffle 107d.
