設備簡介Equipment Introduction

氣動式真空上料機是利用壓縮空氣通過真空發生器產生高真空實現對物料的輸送，不需要機械式真空泵，具有結構簡單、體積小、免維修、噪音低、控制方便、消除物料靜電和符合GMP要求等優點。真空發生器產生的高真空，使被輸送的物料杜絕了分層現象，保證了混合物料成分的均一性，是壓片機、膠囊填充機、干法制粒機、包裝機、粉碎機、振動篩等機械自動上料設備。

The pneumatic vacuum feeder uses compressed air to generate high vacuum through a vacuum generator to transport materials without the need for a mechanical vacuum pump. It has the advantages of simple structure, small volume, maintenance free, low noise, convenient control, elimination of material static electricity, and compliance with GMP requirements. The high vacuum generated by the vacuum generator eliminates the phenomenon of layering in the transported materials, ensuring the uniformity of the composition of the mixed materials. It is the preferred equipment for mechanical automatic feeding, such as tablet presses, capsule filling machines, dry granulation machines, packaging machines, crushers, vibrating screens, etc.

工作原理operational principle

當按下“開/關”按鍵時，壓縮空氣進入真空發生器，同時料斗的放料門在氣缸推動下關閉，料斗中產生真空。真空加料機在真空下形成一股氣流，在這股氣流的作用下，被輸送的物料經軟管輸送到真空料斗中，一定時間后（上料時間，可調整）壓縮空氣被關閉，氣動真空泵無法產生真空，同時料斗的放料門在氣缸推動下開啟，真空加料機真空消失，物料從放料門自動放入受料設備中（如壓片機，包裝機等）。同時，儲存在氣包中的壓縮空氣反吹過濾器，過濾器自動清洗；一定時間后（放料時間，可調節），壓縮空氣重新啟動，氣動真空泵產生真空，放料門關閉，真空加料機再次加料，周而復始，物料被源源不斷地送入受料設備中。

對料位控制的真空加料機，受料設備的料斗中物料通過料位計完成自動加料。當受料設備的料斗高于某一位置時，真空加料機停止動作進入待機狀態；當料位低于某一位置時，真空加料機自動啟動，完成對受料設備的加料。啟動，完成對受料設備的加料。

When the "on/off" button is pressed, compressed air enters the vacuum generator, and at the same time, the discharge door of the hopper is closed under the push of the cylinder, creating a vacuum in the hopper. The vacuum feeder forms an airflow under vacuum, and under the action of this airflow, the conveyed material is transported through a hose to the vacuum hopper. After a certain period of time (feeding time, adjustable), the compressed air is closed, and the pneumatic vacuum pump cannot generate vacuum. At the same time, the discharge door of the hopper is pushed open by the cylinder, and the vacuum of the vacuum feeder disappears. The material is automatically placed into the receiving equipment (such as tablet press, packaging machine, etc.) from the discharge door. At the same time, the compressed air backwash filter stored in the air bag automatically cleans the filter; After a certain period of time (adjustable discharge time), the compressed air restarts, the pneumatic vacuum pump generates vacuum, the discharge door closes, and the vacuum feeder feeds again. The material is continuously fed into the receiving equipment.

 The vacuum feeding machine controls the material level, and the material in the hopper of the receiving equipment is automatically fed through the material level gauge. When the hopper of the receiving equipment is higher than a certain position, the vacuum feeder stops and enters standby mode; When the material level is below a certain position, the vacuum feeding machine automatically starts to complete the feeding of the receiving equipment. Start and complete the feeding of the receiving equipment.
