Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, in particular to a mixing device for cefixime raw materials. Background Art

[0002] During the production process, problems with cefixime tablets include uneven tablet content, excessive dissolution, delayed disintegration, etc. All factors that cause excessive tablet weight variation can lead to uneven drug content in the tablets. In addition, for small-dose drugs, uneven mixing and migration of soluble components are the two main reasons for unqualified tablet content uniformity. When the existing cefixime raw material mixing device is in use, to solve this problem, an adjustable mixing component is installed to make the mixing more uniform and improve the processing efficiency of the device. Although the processing efficiency of the device can be improved to a certain extent, when the device discharges materials, it needs to discharge through the installed discharge port, resulting in a slow discharging speed and affecting the overall processing speed.

[0003] After retrieval, for the Chinese patent document (authorized publication number CN207221787U), the utility model discloses a mixing device for cefixime raw materials, including a stirring tank body and a lid. A discharge port is provided below the side wall of the stirring tank body. A gearbox and a motor connected to the gearbox are provided directly below the stirring tank body. One end of a rotating shaft is connected to the gearbox, and the other end passes through the center position of the bottom of the stirring tank body and a stirring head is installed at the end. The characteristics are as follows: The stirring head includes a cylindrical fixing part installed at the upper end of the rotating shaft and four "one"-shaped stirring blades. The four stirring blades are evenly distributed in the circumferential side wall direction of the fixing part, and one end of each stirring blade is fixedly connected to the fixing part. Each stirring blade is inclined, and the inclined direction faces the opposite direction of the rotation direction. Although this patent can improve the processing efficiency of the device to a certain extent, when the device discharges materials, it needs to discharge through the installed discharge port, resulting in a slow discharging speed and affecting the overall processing speed.
