The automatic medium-pressure preparation and separation equipment comprises a workbench; the sample loading, liquid adding and needle cleaning module, the column packing module, the fraction collecting module, the carrying mechanism and the pump valve module are arranged on the workbench; the mobile phase cache module, the sample loading liquid adding and needle cleaning module which are arranged independent of the workbench are used for sucking sample liquid and cleaning a sample loading needle; chromatographic columns and / or sample loading columns are installed on the column loading module through a carrying mechanism, samples are separated, and the chromatographic columns and / or the sample loading columns of various specifications can be arranged in the column loading module; the fraction collection module is used for collecting fractions; the carrying mechanism is used for transferring materials on the sample loading, liquid adding and needle cleaning module, the column packing module and the fraction collecting module; the mobile phase cache module caches the required mobile phase; and the pump valve module is respectively communicated with the sample loading, liquid adding and needle cleaning module, the column packing module, the fraction collecting module and the mobile phase caching module and is used for providing power for liquid transmission among the modules. According to the invention, automation and unmanned operation of the whole process of medium-pressure preparation and separation are realized.

This utility model provides an automatic gluing device for cardboard box splicing, including a support frame, a conveyor belt, and a glue applicator. The conveyor belt is mounted on the support frame, and the glue applicator is mounted on the upper middle part of the support frame. The glue applicator includes hydraulic rods, a fixed plate, a glue applicator box, and a motor. The hydraulic rods are symmetrically mounted on both sides of the support frame. The two ends of the fixed plate are connected to the hydraulic rods respectively. A moving groove is opened in the middle of the fixed plate, and a screw is installed in the moving groove. The glue applicator box is placed in the moving groove, and the screw passes through the glue applicator box. The motor is located on one side of the fixed plate and connected to the screw. A glue injection pipe is connected to the top of the glue applicator box. This utility model provides an automatic glue applicator for cardboard used in splicing cardboard boxes. It can adjust the width of the glue applicator range, automatically perform positioning glue applicator, significantly improve the efficiency of the glue applicator process, ensure the position of the cardboard is fixed during the glue applicator process, accurately control the amount of glue used, avoid excessive glue application, save glue consumption, ensure glue bonding quality, and reduce drying time.
