  1. structure features

A       Mixing bin holding mechanism

Mixing bin holding mechanism includes lifting motor, reducer, left and right gear transmission mechanism, lifting rod screw nut, all these devices are installed in the rotary body. Rotary body is made of high quality carbon steel and rust proof treated, and covered with SS 304, so it could meet the strengthen requirement as well as GMP requirement.

Screw-nut transmission mechanism, as the lifting holding device of bin blender, it has got good transmission performance and self locking performance, the safety is assured, and the screw nut mechanism is hidden in the revolving body.

Rotary angle designed with gripping column, function together with the rotary body bottom holding leg, to prevent mixing material from sliding out.

B      Rotary Mixing System

Rotary blending system  is low speed rotary body driven by a low speed large torque reducing motor through coupling, the material is moving, sliding, stacking, dispersing, shearing in the bin until the mixing process completes.

The mixing is controlled by inverter, with adjustable rotary speed between 3-15rpm

C      left and right machine arm

The machine frame is made of premium SS, cover is SS 304, with roughness Ra≤0.8, there is zero dead leg or screw on the structure, so it is GMP compliance.

There are two arm structure for the frame, so that the rotary body could be stable and safe. The arm base has got large area to make the load even and running safely.

D      Electric control system

For the control system, all are installed in the control cabinet except the touch screen, printer, emergency switch and sensors.

Electric control cabinet is single door structure for easy operation and maintenance.

PLC and software:  the main parts of control system, to control action of the blender, parameter control and failure troubleshooting, the blending process, quality control, user operation interface is real time controlled and managed.

HMI, touch screen, as operator operation interface, real time operation and running parameter setting, mixing running status, main machine failure status is displayed and monitored on the interface.

Printer: the mixing process, drug name, production batch number, mixing time, mixing rotary speed, production time and operator is recorded.

  1. Safety protection 

In the process of mixing, the bin and holding mechanism is moving with large rotary radius, the safety protection measure is set to protect operators. The infrared photoelectric protection device is set to isolate the rotary area and safety area. When somebody or other items enters the rotary zone, system will stop and send out alarming.
