The utility model discloses a desktop formula test tube labeling machine, including buffer memory device, handling device, labeling device, tray storage device and tray transmission device, buffer memory device is used for buffering test tube, and buffer memory device is equipped with hopper, and the aperture of hopper's mouth is greater than the outer diameter of test tube's pipe cap, and the minimum aperture of hopper is slightly greater than the outer diameter of test tube's pipe cap, handling device is used for handling test tube located in buffer memory device to hopper, the entrance of labeling device is located just below hopper, and labeling device is used for test tube to label, tray storage device can supply tray and storage tray, tray transmission device, tray transmission device can transmit the tray that tray storage device supplies to just below the export of labeling device, and can transmit the tray located just below the export of labeling device to tray storage device and store. It can solve the problem that the existing test tube labeling machine cannot arrange the pipe by oneself, and also cannot classify and store the test tube that labels are completed.

This invention discloses a novel detector method based on a two-stage detection model. This invention has certain versatility within two-stage detection models, and the improved detection model can also be used as a standalone detection framework. To address the problem that traditional two-stage detection models often misclassify new targets as easily confused base class targets in classification tasks, this invention adds a contrastive network to the detector to understand intra-class similarities and inter-class differences. By contrasting object encoding, inter-class errors can be reduced. The patent verifies the feasibility and usability of the algorithm through ablation and contrast experiments, thereby demonstrating the feasibility and rationality of the novel detector proposed in this invention.

This utility model relates to the technical field of deoiling systems and provides a waste catalyst deoiling system. It includes a deoiling furnace, a slag remover, a bucket elevator, a screen, a hopper, and an economizer. The deoiling furnace includes a moving block and a grate. The grate is composed of a crossbeam and grate plates, with the grate plates evenly assembled on the crossbeam. The crossbeam is fixedly connected to the moving block, and pulleys are mounted on the moving block. The rotation of the pulleys causes displacement of the moving block and the grate. The slag remover and the bucket elevator cooperate to feed the material discharged from the slag remover into the screen. The discharge port of the screen connects to the inlet of the hopper. The flue gas outlet of the deoiling furnace is provided with a flue that connects to the economizer. This waste catalyst deoiling system can distribute the force on the grate through the moving block, reducing the grate deformation and lowering the possibility of problems such as material leakage and chain slippage.
