Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a spiral stirring and mixing device. Background Art

[0002] In the process of tablet production, raw material mixing is a common processing step. Usually two or more powder medicines are mixed and the mixing needs to be uniform enough. If the mixing is not uniform, the content of each component in each tablet will be different after the subsequent tablets are made, which will affect the patient's medication and health. Therefore, uniform mixing is an important part of maintaining tablet quality.

[0003] In the production and mixing of commonly used tablets, a variety of different drug powders are directly placed in the mixing equipment and mixed with water. After the various drug powders are placed in the mixing equipment, the various drug powders are clearly layered in the mixing equipment. When mixing the drug powders and water, more mixing time is required to achieve a better mixing effect. In addition, commonly used mixing equipment cannot pre-mix the various drug powders when mixing the drug powders, and gradually mix the pre-mixed drug powders with water, resulting in that the existing mixing equipment has a poor mixing effect when mixing the various drug powders and a low mixing efficiency.

[0032] When the utility model is in use, the staff stores a certain amount of medicine or mixed water for mixing medicines in the four storage chambers 18 at the top of the machine body 1 near the corners. The staff installs the machine cover 2 on the top of the machine body 1. When installing the machine cover 2, the staff can rotate the rotating shaft 5 to adjust the positions of the two limit blocks 15 at the top of the rotating shaft 5. When the staff installs the machine cover 2 on the top of the machine body 1, the top of the rotating shaft 5 is located inside the connecting sleeve 10 at the bottom of the machine cover 2, and the two limit blocks 15 at the top of the rotating shaft 5 are respectively located inside the two card grooves 21 on the connecting sleeve 10, and the output shaft of the motor 3 located at the top of the machine cover 2 is connected to the top of the connecting sleeve 10, so that the motor 3 is connected to the rotating shaft 5 through the connecting sleeve 10, which is convenient for the staff to install and disassemble the machine cover 2 at any time during use, and at the same time does not affect the mixing of medicine powder by the rotating shaft 5.

[0033] When in use, the rubber block 20 at the bottom of the cover 2 is located at the temporal part of the storage cavity 18 at the top of the body 1, and the rubber block 20 can play a good role in limiting the position of the cover 2 through the storage cavity 18.

When in use, the staff can adjust the viscosity of the medicine powder when bonding by adjusting the water spray amount of the water spray port 14. When the medicine powder is mixed, it can be transported to the outside through the connecting block 19 and the external conveying pipe. The staff outside puts the mixed viscous medicine powder into a small medicine model tank and air-dries it, and the mixed medicine can form a number of small tablets.

[0036] When the drug powder is mixed under the partition 8 inside the body 1, several fixing bars 9 on the threaded blades 7 can squeeze the surface of the mixed drug powder, making it convenient for the drug powder to rotate and mix inside the body 1, and preventing the drug powder from sticking to each other and leaving a lot of air inside. When the staff has finished mixing all the drug powders, several water spray ports 14 can clean the surface of the threaded blades 7, and the water sprayed by the water spray ports 14 will flow along the surface of the threaded blades 7, so that the water sprayed by the water spray ports 14 can clean the surface of the threaded blades 7 to the greatest extent.
