Through gear coupling transmission, drive transmission supporting wheel 223 stop rotating, and then drive and rotate gyro wheel 222 and stop rotating to make spacing gyro wheel 221 stop rotating, make finally on the rotatory cage 22 slowly rotate to the initial position under the guide of spacing gyro wheel 221 and spacing and stop, rotatory cage 22 location relies on the positioning switch to feed back the signal. After the positioning is completed, the controller sends a mixed operation completion signal to the alarm 282, and the alarm 282 gives an alarm sound to confirm that the mixed operation of the rotating cage 22 is completed. The printer 285 is started, and the printer 285 prints the mixing operation information of the rotating cage 22 in the rotating and blending process displayed on the display screen 284 through the controller.
When the emergency gate 24 is opened, the gate limit switch is triggered, and the controller sends an emergency gate opening signal to the display screen 284 according to the gate limit switch 251. Through the rotation of the pressing knob 25, the pressing plate 26 is lifted, the inner vehicle 11 is pulled out from the rotating cage 22, then the tank wagon 12 and the inner vehicle 11 are locked through the interlocking switch 13, the front section of the outer guide rail 121 of the tank wagon 12 is separated from the limiting hole 271 on the rotating cage 22, and the inner vehicle 11 is pulled out of the rotating cage 22 through the frame opening 23. The tank wagon 12 is pushed to a subsequent process place through a direction wheel at the bottom of the tank wagon 12, a net fence 112 at one end of the inner wagon 11 is opened, a plurality of turnover tables are taken out from a plurality of layered supports 111 in the inner wagon 11, the turnover tables are opened, and the uniformly mixed liquid preparation is taken out for subsequent processes. At the same time, the power switch 281 on the control panel 28 is closed.
The above steps are repeated again using the above apparatus.
Comparative example 1
The liquid preparation is mixed according to the conventional manual method, namely the liquid preparation is taken and put into a week rotary table, a cover with a soft cushion at the edge is taken to cover the week rotary table, the week rotary table is manually moved up to the position in front of the chest, and the liquid preparation is turned over for a plurality of times up, down, left and right. And opening the cover, and taking out the uniformly mixed liquid preparation for subsequent processes.
Example 2
Comparing the mixing method of example 1 with that of comparative document 1, the mixing method of the present invention using the apparatus can save labor; moreover, a plurality of circumference rotating discs such as 36 discs can be loaded on the inner vehicle at the same time, so that the production efficiency is obviously improved; and a plurality of week carousel carries out synchronous revolution, and the rocking disc is stable good, and the uniformity of mixing liquid is good. Therefore, the automatic rotation of the device is obviously superior to manual tray-rocking operation.
In conclusion, according to the equipment for uniformly mixing the liquid preparation and the application thereof provided by the invention, the automatic rotating mechanical equipment is adopted to replace manual tray shaking operation, so that the uniform mixing of products in multiple trays can be realized, and the equipment is convenient to operate, reliable in performance, safe and stable, and very worthy of popularization and application. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
