[0002] As a healthcare industry bridging health sciences and chemical sciences, pharmacy's responsibility is to ensure the safe and effective use of medicines. Its main research areas include the source, properties, effects, formulation, analysis, production, storage, and discovery of new drugs. Its primary task is to continuously improve drug quality and provide more effective medications. The mission of pharmacy is to ensure medication safety, enabling patients to treat or cure diseases with minimal harm and maximum benefit. In the process of analyzing drug effects, multiple experiments are often required, involving the mixing of different drugs. However, current methods for mixing drugs mostly rely on manually rotating a power shaft to drive the stirring blades, combined with manual shaking. This method is not only time-consuming and labor-intensive but also results in low mixing quality. Therefore, a premixing and stirring device for drug analysis is needed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a premixing and stirring device for drug analysis to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A premixing and stirring device for drug analysis includes a support plate, a mounting frame mounted on the support plate, a limiting groove formed on the support plate, a limiting block slidably mounted in the limiting groove, a limiting rod hinged to the limiting block, a housing hinged to the end of the limiting rod away from the limiting block, a sliding groove formed on the side wall of the mounting frame, a connecting plate slidably mounted in the sliding groove, the end of the connecting plate away from the sliding groove connected to the housing, a shell opening provided on the housing, a guide groove formed on the top of the mounting frame, a drive box slidably mounted in the guide groove, a drive component provided in the drive box, a drive rod mounted on the output end of the drive component, the end of the drive rod away from the drive component extending through the drive box into the housing, and a stirring rod mounted on the drive rod;

One end of the transmission assembly is connected to the drive assembly, and the other end is connected to the drive housing. The mounting bracket is also equipped with a transmission mechanism, one end of which is connected to the drive assembly, and the other end is connected to the connecting plate.

[0007] As a further embodiment of this utility model: the drive assembly includes a drive component, which is mounted on a mounting bracket. A drive shaft is mounted on the output end of the drive component, and the drive shaft is rotatably connected to the mounting bracket.

[0008] As a further embodiment of this utility model: the transmission assembly includes a driven shaft, one end of which is rotatably connected to the mounting bracket, a cam is connected to the end of the driven shaft away from the mounting bracket, a connecting rod is rotatably connected to the end of the cam away from the driven shaft, and the end of the connecting rod away from the cam is hinged to the drive box.

[0009] A connecting unit is installed on the drive shaft, and the end of the connecting unit away from the drive shaft is connected to the driven shaft.

[0010] As a further embodiment of this utility model: the transmission mechanism includes an elastic component, one end of which is connected to the top wall of the slide groove, and the other end is connected to the connecting plate;

[0011] A rotating shaft is rotatably mounted on the side wall of the mounting frame, and a rotating plate is fixedly connected to the end of the rotating shaft away from the mounting frame.

During this process, the driving component drives the driving shaft connected to it to rotate. The rotation of the driving shaft drives the driven shaft to rotate through the connecting unit. The rotation of the driven shaft drives the cam connected to it to rotate. Under the action of the connecting rod, the rotation of the cam drives the driving box on one side to slide back and forth in the guide groove, so that the driving box drives the stirring rod at the bottom to stir multiple positions in the shell, thereby increasing the stirring range. The rotation of the driving shaft drives the rotating shaft to rotate through the connecting mechanism. The rotation of the rotating shaft drives the rotating plate connected to it to rotate. The rotating plate intermittently contacts the connecting plate. When the rotating plate contacts the connecting plate, it will drive the connecting plate to move downward.

In this way, the shell is continuously shaken up and down, so that the raw materials inside can be continuously turned over. Combined with the stirring rod stirring multiple positions, the raw materials are mixed more thoroughly. Attached Figure Description
