[0029] Through the cooperation between the card block 301 and the card slot 202, the dissolving barrel 3 can be installed, making the taking and placing operation more convenient, and the dissolving barrel 3 can also be rotated following the circular mounting plate 2. Through the cooperation between the limit block 203 and the limit slot 1021, the circular mounting plate 2 is rotatably set inside the first circular groove 102.

[0030] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the grinding mechanism 6 includes a mounting frame 601, which is mounted on one end surface of the mounting box 5, a first driving motor 602 is mounted on one end surface of the mounting frame 601, two first rotating rods 603 are rotatably mounted on one end surface of the mounting box 5, one end of each first rotating rod 603 is rotatably set on one end surface of the mounting box 5, one end of one of the first rotating rods 603 is fixedly connected to the output end of the first driving motor 602, a driving gear 604 is fixedly mounted on the rod body of each first rotating rod 603, second rotating rods 605 are rotatably mounted on both sides of one end surface of the mounting frame 601, a driven gear 606 is fixedly mounted on the rod body of each second rotating rod 605, the two driving gears 604 are meshed with each other, and the two driving gears 604 are also respectively meshed with the driven gear 606, and a grinding roller 607 is mounted on one end of each second rotating rod 605 located inside the mounting box 5, and one end of the grinding roller 607 is rotatably set on the inner wall of one end of the mounting box 5.

[0031] Through the meshing between the driving gear 604 and the driven gear 606, when the first driving motor 602 is driven, the rotation direction of the two grinding rollers 607 can be controlled, so that the medicine can be ground. There is no need to manually crush large volumes of medicines. The medicines ground into powder can also be dissolved faster, which can effectively shorten the time and improve the dissolution efficiency.

[0032] like Figure 4 As shown, a mounting groove 401 is provided on one side surface of each side plate 4, and the adjusting mechanism 7 includes a second driving motor 701, and the second driving motor 701 is installed on the top of one of the side plates 4, and an adjusting screw rod 702 is installed at the output end of the second driving motor 701, and one end of the adjusting screw rod 702 is rotatably set on the bottom inner wall of the mounting groove 401 at the corresponding position, and a screw rod sleeve 703 is movably installed on the rod body of the adjusting screw rod 702, and a sliding rod 704 is installed inside the mounting groove 401 away from the adjusting screw rod 702, and a sliding block 705 is slidably set on the rod body of the sliding rod 704, and one end of the sliding block 705 and the screw rod sleeve 703 are both installed with connecting plates 706, and one end of the two connecting plates 706 are respectively installed on the two end surfaces of the mounting box 5.

[0033] By adjusting the meshing transmission between the screw rod 702 and the screw rod sleeve 703, the installation box 5 can be controlled to move under the drive of the second drive motor 701, which is convenient for taking and placing the dissolving barrel 3. Through the sliding cooperation between the sliding block 705 and the sliding rod 704, the moving trajectory of the installation box 5 can be limited, making it more stable during the movement.

[0034] like Figure 4 As shown, through grooves 501 are provided on the upper and lower end surfaces of the installation box 5, a plurality of first stirring rods 302 are evenly distributed on the inner wall of the dissolving barrel 3, a mounting rod 502 is rotatably installed on one side of the lower surface of the installation box 5, and a plurality of second stirring rods 503 are evenly distributed on the rod body of the installation rod 502.

[0035] When the first stirring rod 302 rotates with the dissolving barrel 3, its end will push the second stirring rod 503 to rotate, so that it can stir over a larger range, fully stir the medicine and make it dissolve faster. The installation rod 502 is rotatably set at the bottom of the installation box 5 and can move with the installation box 5.

[0036] The working principle of this drug preparation pharmacology experiment dissolution device:

[0037] When in use, the dissolving barrel 3 is installed into the inside of the second circular groove 201 through the cooperation of the block 301 and the slot 202, and the solvent is introduced into the inside of the dissolving barrel 3, and then the adjusting screw rod 702 is driven to rotate by the second driving motor 701. Under the meshing action between the adjusting screw rod 702 and the screw rod sleeve 703, the installation box 5 can be controlled to move up and down, and the installation box 5 is moved down to a position closer to the top of the dissolving barrel 3, so that the installation rod 502 and the second stirring rod 503 are located inside the dissolving barrel 3, and one of the first rotating rods 603 is driven to rotate by the first driving motor 602. Under the meshing action between the two driving gears 604 and the driven gear 606, the two second rotating rods 605 can be driven to rotate in the opposite direction, and the medicine can be put into between the two grinding rollers 607 through the upper through slot 501. The two grinding rollers 607 rotate in opposite directions to grind the medicine. The powder will fall into the interior of the dissolving barrel 3 through the through groove 501 on the lower side. When dissolving a large volume of medicine, there is no need for manual crushing, which saves time and can effectively avoid the waste caused by manual crushing of medicine. The servo motor 101 drives the circular mounting plate 2 to rotate, so that the dissolving barrel 3 and the first stirring rod 302 inside rotate accordingly. During the rotation of the first stirring rod 302, the end portion will contact the second stirring rod 503. The mounting rod 502 is rotated so that the first stirring rod 302 can push the second stirring rod 503 to rotate around the mounting rod 502 as the axis during the rotation, thereby having a larger range, which can effectively speed up the dissolution speed of the medicine and is more efficient. After the dissolution is completed, the mounting box 5 is moved up by the drive of the second drive motor 701, so that the mounting rod 502 is moved out of the dissolving barrel 3, making it convenient to remove the dissolving barrel 3.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
