真空上料機(jī)是在廣泛吸收國(guó)內(nèi)外同類產(chǎn)品的基礎(chǔ)上開發(fā)研制的新產(chǎn)品，目前它是國(guó)內(nèi)*為、理想、完善的粉狀料、粒狀料、粉粒料混合料的真空輸送設(shè)備。真空加料機(jī)能自動(dòng)地將各種物料輸送到料倉(cāng)、包裝機(jī)、注塑機(jī)、粉碎機(jī)等設(shè)備的料斗中，也能直接把混合的物料輸送到混合機(jī)（如V型混合機(jī)、二維混合機(jī)、三維混合機(jī)等）中，減輕了工人的勞動(dòng)強(qiáng)度，了加料時(shí)粉塵外溢等問(wèn)題，是制藥廠、食品廠通過(guò)GMP認(rèn)證、促進(jìn)清潔、文明生產(chǎn)的優(yōu)選設(shè)備。

　　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.

　　真空上料機(jī)由真空泵（無(wú)油、無(wú)水）、真空料斗、過(guò)濾器（有聚酯覆膜過(guò)濾器、PE過(guò)濾器、316L不銹鋼過(guò)濾器或鈦金屬過(guò)濾器多種選擇）、壓縮空氣反吹裝置、氣動(dòng)放料門裝置、料位自動(dòng)控制裝置、不銹鋼吸料咀、輸送軟管等組成，整套系統(tǒng)設(shè)計(jì)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.

　　氣動(dòng)式真空上料機(jī)是利用壓縮空氣通過(guò)真空發(fā)生器產(chǎn)生高真空實(shí)現(xiàn)對(duì)物料的輸送，不需要機(jī)械式真空泵，具有結(jié)構(gòu)簡(jiǎn)單、體積小、免維修、噪音低、控制方便、物料靜電和符合GMP要求等優(yōu)點(diǎn)。真空發(fā)生器產(chǎn)生的高真空，使被輸送的物料杜絕了分層現(xiàn)象，保證了混合物料成份的均一性，是壓片機(jī)、膠囊填充機(jī)、干法制粒機(jī)、包裝機(jī)、粉碎機(jī)、振動(dòng)篩等機(jī)械自動(dòng)上料的優(yōu)選設(shè)備。

　　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.

　　當(dāng)壓縮空氣供給真空發(fā)生器時(shí)，真空發(fā)生器就產(chǎn)生負(fù)壓形成真空氣流，物料被吸入吸料咀，形成物氣流，經(jīng)過(guò)吸料管到達(dá)上料機(jī)的料倉(cāng)內(nèi)。過(guò)濾器把物料與空氣徹底分離，當(dāng)物料裝滿料倉(cāng)時(shí)，控制器會(huì)自動(dòng)切斷氣源，真空發(fā)生器停止工作，同時(shí)料倉(cāng)門自動(dòng)開啟，物料落到設(shè)備的料斗中。與此同時(shí)，壓縮空氣通過(guò)脈沖反吹閥自動(dòng)清洗過(guò)濾器。等到時(shí)間到或料位傳感器發(fā)出上料信號(hào)時(shí)，自動(dòng)啟動(dòng)加料機(jī)。

　　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.

　　粉體真空稱重系統(tǒng)由投料站或物料儲(chǔ)倉(cāng)、真空加料機(jī)稱重裝置、PLC控制器等部件組成，可完成單物料定重量加料或多種物料不同配方配料的自動(dòng)供料配料。廣泛應(yīng)用于醫(yī)藥、食品、化工、電池材料、建材、冶金、飼料加工等行業(yè)。

　　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.

　　以粉體真空稱重系統(tǒng)應(yīng)用于兩種物料自動(dòng)稱重配料為例說(shuō)明粉體真空承重系統(tǒng)的工作原理。物料A、B分別儲(chǔ)存在兩個(gè)料倉(cāng)中，粉體真空稱重系統(tǒng)開始工作，真空泵啟動(dòng)，物料A粉倉(cāng)底部螺旋放料閥A達(dá)到一定重量時(shí)，螺旋停止，放料閥A關(guān)閉，剩余在輸送管中的物料繼續(xù)被吸入到稱重料斗中，吸凈后秤中物料A的重量正好是設(shè)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.

　　此時(shí)，物料B料倉(cāng)底部螺旋放料閥B打開，螺旋啟動(dòng)，物料B被吸入稱重料斗中，秤中物料B達(dá)到一定重量時(shí)，螺旋停止，放料閥B關(guān)閉，剩余在輸送管中的物料繼續(xù)被吸入到稱重料斗中，吸凈后秤中物料B的重量正好是設(shè)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.

　　粉體真空稱重系統(tǒng)較傳統(tǒng)的粉體稱重系統(tǒng)具有工藝流程短、稱重精度高、可靠性高、設(shè)備布局高度靈活、大幅降低廠房高度等優(yōu)點(diǎn)。根據(jù)稱重裝置在粉體真空稱重系統(tǒng)中不同位置，可組成多種加法秤、減法秤，以適應(yīng)客戶的不同要求。

　　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.
