Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a high-speed mixer with a scraper plate for producing medical polymer materials. Background Art

[0002] High-speed mixer for medical polymer material production is a kind of equipment used for mixing materials in medical device production. It evenly mixes different polymer materials through a high-speed rotating agitator. This equipment can effectively improve the mixing efficiency and quality, ensure the uniformity and stability of medical materials, and thus produce products that meet medical standards.

[0003] The existing high-speed mixer for producing medical polymer materials usually uses a mixing and stirring structure to mix the medical polymer materials. When mixing the medical polymer materials, the medical polymer materials will adhere to the inner wall of the mixing barrel, which is inconvenient to clean the adhered medical polymer materials, resulting in waste of medical polymer materials and increased use costs. Therefore, we propose a high-speed mixer for producing medical polymer materials with a scraper. Utility Model Content

[0004] The purpose of the utility model is to provide a high-speed mixer for producing medical polymer materials with a scraper plate to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Further: the mixing mechanism includes a servo motor, the servo motor is located on the top of the top cover, and the output end of the servo motor is connected to a driving rod, and a plurality of mixing and stirring rods are installed on the outer wall of the driving rod.

[0008] Furthermore: the rotating mechanism also includes a circular groove opened on the inner wall of the circular sleeve, and a connecting slider is slidably connected in the circular groove, and the outer wall of the connecting slider is connected to the side wall of the reduction motor.

[0009] Furthermore: the output end of the reduction motor is connected to a rotating shaft, and a rotating gear is installed at the bottom of the rotating shaft. The inner wall of the circular sleeve is provided with multiple sets of meshing tooth grooves, and the multiple sets of meshing tooth grooves are meshed and connected with the rotating gear.

[0010] Furthermore: three groups of support rods are distributed in a circular array on the outer wall of the mixing cylinder, and the top cover is located at the top of the inner cavity of the mixing cylinder.

[0011] Furthermore: the inner wall of the circular groove and the outer surface of the connecting slide block are coated with lubricating oil.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model can drive multiple groups of mixing and stirring rods on the outer wall of the driving rod to rotate through the operation of the servo motor, thereby realizing high-speed mixing of medical polymer materials. The operation of the reduction motor can drive the rotating gear to rotate. Since the rotating gear is meshingly connected with the multiple groups of meshing teeth and grooves, the reduction motor is limited by the sliding of the connecting slider and the circular groove, so that the connecting rod drives the scraper plate to rotate on the inner wall of the mixing barrel, thereby realizing the scraping of the medical polymer materials bonded to the inner wall of the mixing barrel, avoiding the medical polymer materials from being bonded to the inner wall of the mixing barrel, making the bonded medical polymer materials mixed more evenly, and avoiding the waste of medical polymer materials.
