Abstract
Description
Technical Field

[0002] Ointment refers to a semi-solid external preparation with a certain consistency made by uniformly mixing the drug with a suitable matrix; The viscosity of ointments is one of the core indicators of their quality control, directly affecting the drug's spreadability, penetration efficiency, and clinical efficacy. During the viscosity measurement process, the refrigerated ointment must first be heated to room temperature. During the heating process, stirring is often a common method to accelerate heating efficiency. Although domestic and international pharmacopoeias have standardized viscosity measurement methods, there are still significant deficiencies in standardized stirring technologies for the complex rheological properties of ointments. A fixed stirring blade structure is commonly used in existing testing processes. When the stirring rod rotates, mixing is achieved only through the circular motion of the blade. Traditional stirring relies only on the radial force generated by rotation and lacks vertical disturbance.

[0022] Specifically, such as Figure 9-10As shown, the drive assembly includes a second motor 11 provided on the storage plate 6 at a symmetrical position corresponding to the conical drop body 9. The output end of the second motor 11 passes through the storage plate 6 and is connected to a connecting shaft 37.

During the downward movement of the second motor 11, the elastically arranged insert block 40 contacts the upper end of the rotating shaft 14. At this time, the insert block 40 is directly inserted into the slot 41, or the insert block 40 is held by the upper end of the rotating shaft 14 into the receiving groove 38. Then, under the rotation of the connecting shaft 37, the insert block 40 is rotated and inserted into the slot 41.

[0025] The present invention specifically comprises the following steps: placing the ointment storage tube 8 containing the ointment medicine between the two sets of clamping plates 7, and then driving the second transmission screw 13 to rotate by the conical drop 9. During the rotation of the second transmission screw 13, the two sets of clamping plates 7 approach each other to clamp the ointment storage tube 8 containing the ointment medicine.

During the stirring process, the electric telescopic rod 26 is started, and the electric telescopic rod 26 drives the first adjustment rod 24 to move back and forth. During the movement, the first bevel groove 25 and the first bevel block 28 cooperate to drive the second adjustment rod 30 to move back and forth. During the reciprocating movement of the second adjustment rod 30, the second bevel block 32 and the second bevel groove 31 cooperate to achieve the up and down swinging of the multiple groups of stirring blades 22 during the stirring process, which can promote the material exchange between the upper and lower layers of the ointment and reduce the heating time; After the stirring is completed, the storage plate 6 is directly lifted by the lifting component. At this time, the ointment medicine inside the ointment storage tube 8 is no longer stirred, and then the third motor 16 is started. The third motor 16 drives the transmission gear 18 to rotate through the transmission shaft 17. During the rotation process, the transmission gear 18 drives the storage plate 6 to rotate through the cooperation of the transmission gear ring 19, and rotates the conical drop 9 to the top of the ointment storage tube 8. Then, the lifting component is started to make the lower end of the conical drop 9 contact with the surface of the ointment medicine in the ointment storage tube 8, and then the magnetic attraction of the magnetic fixing frame 10 to the conical drop 9 is cancelled, and the lower end of the conical drop 9 penetrates into the interior of the ointment medicine, and the viscosity of the ointment medicine is measured by the penetration depth.
