真空上料机是在广泛吸收国内外同类产品的基础上开发研制的新产品，目前它是国内*为先进、理想、完善的粉状料、粒状料、粉粒料混合料的真空输送设备。真空加料机能自动地将各种物料输送到料仓、包装机、注塑机、粉碎机等设备的料斗中，也能直接把混合的物料输送到混合机（如V型混合机、二维混合机、三维混合机等）中，减轻了工人的劳动强度，解决了加料时粉尘外溢等问题，是制药厂、食品厂通过GMP认证、促进清洁、文明生产的优选设备。

　　The vacuum feeder is a new product developed on the basis of widely absorbing similar products at home and abroad. Currently, it is the most advanced, ideal, and perfect vacuum conveying equipment for powdered materials, granular materials, and powder granular mixtures in China. The vacuum feeding machine can automatically transport various materials to the hoppers of equipment such as silos, packaging machines, injection molding machines, crushers, etc. It can also directly transport mixed materials to mixers (such as V-mixers, 2D mixers, 3D mixers, etc.), reducing the labor intensity of workers and solving problems such as dust overflow during feeding. It is the preferred equipment for pharmaceutical and food factories to pass GMP certification and promote clean and civilized production.

　　真空上料机由真空泵（无油、无水）、真空料斗、过滤器（有聚酯覆膜过滤器、PE过滤器、316L不锈钢过滤器或钛金属过滤器多种选择）、压缩空气反吹装置、气动放料门装置、料位自动控制装置、不锈钢吸料咀、输送软管等组成，整套系统设计合理、制造精美。

　　The vacuum feeding machine consists of a vacuum pump (oil-free, waterless), a vacuum hopper, a filter (with multiple options including polyester film filter, PE filter, 316L stainless steel filter or titanium metal filter), a compressed air blowback device, a pneumatic discharge door device, a material level automatic control device, a stainless steel suction nozzle, a conveying hose, etc. The entire system is designed reasonably and manufactured beautifully.

　　气动式真空上料机是利用压缩空气通过真空发生器产生高真空实现对物料的输送，不需要机械式真空泵，具有结构简单、体积小、免维修、噪音低、控制方便、消除物料静电和符合GMP要求等优点。真空发生器产生的高真空，使被输送的物料杜绝了分层现象，保证了混合物料成份的均一性，是压片机、胶囊填充机、干法制粒机、包装机、粉碎机、振动筛等机械自动上料的优选设备。

　　Pneumatic vacuum feeder uses compressed air to generate high vacuum through a vacuum generator to transport materials, without the need for mechanical vacuum pumps. It has the advantages of simple structure, small volume, maintenance free, low noise, easy 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 conveyed material, ensuring the uniformity of the mixed material composition. It is the preferred equipment for mechanical automatic feeding such as tablet press, capsule filling machine, dry granulation machine, packaging machine, crusher, vibrating screen, etc.

　　当压缩空气供给真空发生器时，真空发生器就产生负压形成真空气流，物料被吸入吸料咀，形成物气流，经过吸料管到达上料机的料仓内。过滤器把物料与空气彻底分离，当物料装满料仓时，控制器会自动切断气源，真空发生器停止工作，同时料仓门自动开启，物料落到设备的料斗中。与此同时，压缩空气通过脉冲反吹阀自动清洗过滤器。等到时间到或料位传感器发出上料信号时，自动启动加料机。

　　When compressed air is supplied to the vacuum generator, the vacuum generator generates negative pressure to form a vacuum airflow. The material is sucked into the suction nozzle to form a material airflow, which passes through the suction tube and reaches the feeding bin of the feeder. The filter completely separates the material from the air. When the material is filled in the silo, the controller will automatically cut off the air source, the vacuum generator will stop working, and the silo door will automatically open, allowing the material to fall into the hopper of the equipment. At the same time, compressed air automatically cleans the filter through a pulse blowback valve. When the time is up or the level sensor sends out a feeding signal, the feeder will automatically start.

　　粉体真空称重系统由投料站或物料储仓、真空加料机称重装置、PLC控制器等部件组成，可完成单物料定重量加料或多种物料不同配方配料的自动供料配料。广泛应用于医药、食品、化工、电池材料、建材、冶金、饲料加工等行业。

　　The powder vacuum weighing system consists of a feeding station or material storage bin, a vacuum feeding machine weighing device, a PLC controller, and other components. It can complete the automatic feeding and batching of single material by weight or multiple materials with different formulas. Widely used in industries such as pharmaceuticals, food, chemicals, battery materials, building materials, metallurgy, and feed processing.

　　以粉体真空称重系统应用于两种物料自动称重配料为例说明粉体真空承重系统的工作原理。物料A、B分别储存在两个料仓中，粉体真空称重系统开始工作，真空泵启动，物料A粉仓底部螺旋放料阀A达到一定重量时，螺旋停止，放料阀A关闭，剩余在输送管中的物料继续被吸入到称重料斗中，吸净后秤中物料A的重量正好是设定的重量。

　　Taking the application of powder vacuum weighing system in automatic weighing and batching of two types of materials as an example to illustrate the working principle of powder vacuum load-bearing system. Materials A and B are stored in two silos respectively. The powder vacuum weighing system starts working, the vacuum pump starts, and when the screw discharge valve A at the bottom of the powder silo of material A reaches a certain weight, the screw stops and the discharge valve A closes. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After suction, the weight of material A in the scale is exactly the set weight.

　　此时，物料B料仓底部螺旋放料阀B打开，螺旋启动，物料B被吸入称重料斗中，秤中物料B达到一定重量时，螺旋停止，放料阀B关闭，剩余在输送管中的物料继续被吸入到称重料斗中，吸净后秤中物料B的重量正好是设定的重量。真空泵停止。

　　At this time, the spiral discharge valve B at the bottom of material bin B is opened, and the spiral is started. Material B is sucked into the weighing hopper. When material B reaches a certain weight in the scale, the spiral stops and the discharge valve B is closed. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After suction, the weight of material B in the scale is exactly the set weight. The vacuum pump has stopped.

　　粉体真空称重系统较传统的粉体称重系统具有工艺流程短、称重精度高、可靠性高、设备布局高度灵活、大幅降低厂房高度等优点。根据称重装置在粉体真空称重系统中不同位置，可组成多种加法秤、减法秤，以适应客户的不同要求。

　　The powder vacuum weighing system has the advantages of shorter process flow, higher weighing accuracy, higher reliability, highly flexible equipment layout, and significantly reduced plant height compared to traditional powder weighing systems. According to the different positions of the weighing device in the powder vacuum weighing system, various addition scales and subtraction scales can be formed to meet the different requirements of customers.
