Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the technical field of multi-component material mixing stirrer, concretely relates to a magnetic auxiliary planetary rotary mechanism for vacuum centrifugal stirrer. BACKGROUND

[0002] As a key material for additive manufacturing, uniform mixing of inorganic slurry is very important. Currently, the preparation process of inorganic slurry is as follows: first, solid and liquid phases are loaded into a material cup, and then a contact type mixing device is used for stirring. During mixing, air bubbles are easily generated, and it is difficult to stir uniformly, which is low in efficiency. Moreover, the stirring blade is easy to contaminate the slurry and adhere to the slurry, causing a large amount of material waste, and it is also difficult to clean thoroughly, which can easily lead to cross-contamination of materials. On the other hand, bone cement is a kind of surgical implant medical device for minimally invasive injection or local filling. During the operation, the solid and liquid phases of the bone cement need to be uniformly mixed and prepared into a slurry with a certain viscosity and then loaded into a mixing syringe for in vivo injection and filling, so uniform stirring is an essential step. In clinical applications, manual stirring is usually used. However, the bone cement has a high viscosity, and the operation process is not only laborious, but also increases the risk of contamination and material waste during the transfer and loading of the mixing syringe, and the complicated operation process prolongs the operation preparation time. At the same time, there is a large difference in the density of the main components and the developer of the existing bone cement, and the traditional stirring cannot efficiently and quickly and fully ensure the uniform mixing of each component, and manual stirring is easy to introduce air, which ultimately leads to a decrease in mechanical strength and cannot meet the requirements of clinical applications.

[0003] A needle cylinder type vacuum defoaming stirrer device is disclosed in Chinese Patent No. CN209423463U. The needle cylinder is detachably mounted on the needle cylinder mounting seat. A plurality of self-rotating gears are driven to rotate by the driving main gear, and then the self-rotating gears drive the needle cylinder on the mounting seat to rotate, so that the slurry in the needle cylinder can be defoamed and stirred. After stirring is completed, the needle cylinder is directly removed for subsequent operation, without material waste and environmental pollution. However, during high-speed operation of the existing stirrer, in order to ensure the static and dynamic balance of the rotating mechanism, it is usually necessary to manually adjust the counterweight or strictly control the quality of the stirred slurry. Manual adjustment of the counterweight is troublesome and requires high skill of the operator. The control of the quality of the stirred slurry needs to rely on accurate weighing with a balance, and the quality of the stirred slurry must be fixed each time, which is extremely inconvenient to operate and use, and also causes waste of slurry due to different needs in clinical use. At the same time, the structure of the existing stirrer is complex, especially the driving main gear drives a plurality of self-rotating gears to rotate, which not only increases the production cost, but also has poor gear transmission stability, which can cause noise pollution and maintenance cost.

Then, the vacuum inside the vacuum box is pumped. When the vacuum degree reaches-100 KPa, the revolving speed motor 11 is turned on. The speed of the revolving speed motor 11 is set to a low speed state of 20 revolutions / min. At the same time, the micro speed motor 33 is started to drive the self-rotating base 41 to rotate. The self-rotating base 41 gradually realizes self-rotation, and reaches 1000 revolutions / min. Then, the micro speed motor 33 is gradually lifted, and is gradually lifted to 3000 revolutions / min.
