在物料輸送系統(tǒng)中，旋轉(zhuǎn)供料器如同一位精準(zhǔn)的 “物料分配員”，而其轉(zhuǎn)速則是控制物料輸送量的關(guān)鍵 “閥門(mén)”。如何巧妙調(diào)節(jié)旋轉(zhuǎn)供料器的轉(zhuǎn)速，讓物料按需、穩(wěn)定地輸送？這里面藏著一套精妙的 “調(diào)節(jié)密碼”，從機(jī)械調(diào)節(jié)到智能控制，多種方式各有千秋。

　　In the material conveying system, the rotating feeder is like a precise "material distributor", and its speed is the key "valve" that controls the amount of material conveyed. How to cleverly adjust the speed of the rotating feeder to ensure that materials are transported as needed and stably? There is a sophisticated set of "adjustment codes" hidden here, ranging from mechanical adjustment to intelligent control, each with its own advantages.

　　機(jī)械變速調(diào)節(jié)是較為基礎(chǔ)且直觀的方式。這種調(diào)節(jié)方式通常依賴于機(jī)械傳動(dòng)裝置，如皮帶輪變速系統(tǒng)。通過(guò)更換不同直徑的皮帶輪，改變主動(dòng)輪與從動(dòng)輪之間的傳動(dòng)比，從而實(shí)現(xiàn)旋轉(zhuǎn)供料器轉(zhuǎn)速的改變。例如，增大從動(dòng)輪直徑、減小主動(dòng)輪直徑，就會(huì)降低供料器的轉(zhuǎn)速；反之則提高轉(zhuǎn)速。還有齒輪變速機(jī)構(gòu)也常被應(yīng)用，通過(guò)不同齒數(shù)齒輪的組合嚙合，實(shí)現(xiàn)多級(jí)變速。齒輪傳動(dòng)具有傳動(dòng)比準(zhǔn)確、效率高的特點(diǎn)，能夠較為穩(wěn)定地調(diào)節(jié)轉(zhuǎn)速。不過(guò)，機(jī)械變速調(diào)節(jié)往往需要停機(jī)操作，并且更換部件較為繁瑣，適合在生產(chǎn)工況相對(duì)固定、轉(zhuǎn)速調(diào)節(jié)頻率不高的場(chǎng)景下使用。

　　Mechanical variable speed adjustment is a relatively basic and intuitive way. This adjustment method usually relies on mechanical transmission devices, such as pulley speed change systems. By replacing pulleys of different diameters and changing the transmission ratio between the driving and driven wheels, the rotational speed of the rotary feeder can be altered. For example, increasing the diameter of the driven wheel and decreasing the diameter of the driving wheel will reduce the speed of the feeder; Conversely, increase the rotational speed. Gear transmission mechanisms are also commonly used, which achieve multi-stage transmission through the combination of gears with different numbers of teeth. Gear transmission has the characteristics of accurate transmission ratio and high efficiency, and can adjust the speed relatively stably. However, mechanical variable speed adjustment often requires shutdown operation and component replacement is cumbersome, making it suitable for use in scenarios where production conditions are relatively fixed and the frequency of speed adjustment is not high.

　　變頻調(diào)速是如今更為普遍和便捷的調(diào)節(jié)方式。它借助變頻器來(lái)改變旋轉(zhuǎn)供料器電機(jī)的供電頻率，從而實(shí)現(xiàn)轉(zhuǎn)速的連續(xù)調(diào)節(jié)。變頻器通過(guò)內(nèi)部電路，將固定頻率的交流電轉(zhuǎn)換為頻率可變的交流電輸出給電機(jī)。根據(jù)電磁感應(yīng)原理，電機(jī)的轉(zhuǎn)速與供電頻率成正比，當(dāng)降低供電頻率時(shí)，電機(jī)轉(zhuǎn)速隨之下降，供料器的轉(zhuǎn)速也變慢，物料輸送量減少；提高供電頻率，則轉(zhuǎn)速和輸送量增加。變頻調(diào)速具有調(diào)節(jié)范圍廣、精度高、響應(yīng)速度快的優(yōu)勢(shì)，能夠在設(shè)備運(yùn)行過(guò)程中實(shí)時(shí)調(diào)整轉(zhuǎn)速，以適應(yīng)不同的生產(chǎn)需求。此外，它還具備節(jié)能效果，在轉(zhuǎn)速降低時(shí)，電機(jī)的功率消耗也相應(yīng)減少，降低了運(yùn)行成本。而且，變頻調(diào)速系統(tǒng)可以與自動(dòng)化控制系統(tǒng)相連，通過(guò)預(yù)設(shè)程序或外部信號(hào)指令，實(shí)現(xiàn)轉(zhuǎn)速的自動(dòng)調(diào)節(jié)。

　　Variable frequency speed regulation is now a more common and convenient way of adjustment. It uses a frequency converter to change the power supply frequency of the rotating feeder motor, thereby achieving continuous adjustment of the speed. The frequency converter converts fixed frequency AC power into variable frequency AC power through internal circuits and outputs it to the motor. According to the principle of electromagnetic induction, the speed of the motor is proportional to the power supply frequency. When the power supply frequency is reduced, the speed of the motor decreases, the speed of the feeder also slows down, and the amount of material conveyed decreases; Increasing the power supply frequency leads to an increase in speed and delivery capacity. Variable frequency speed regulation has the advantages of wide adjustment range, high precision, and fast response speed. It can adjust the speed in real time during equipment operation to meet different production needs. In addition, it also has energy-saving effects. When the speed decreases, the power consumption of the motor is correspondingly reduced, reducing operating costs. Moreover, the variable frequency speed regulation system can be connected to the automation control system to achieve automatic speed adjustment through preset programs or external signal commands.

　　液壓調(diào)速方式在一些對(duì)調(diào)速穩(wěn)定性要求較高的場(chǎng)合發(fā)揮著獨(dú)特作用。旋轉(zhuǎn)供料器的驅(qū)動(dòng)裝置采用液壓馬達(dá)，通過(guò)調(diào)節(jié)液壓系統(tǒng)中的流量和壓力來(lái)控制液壓馬達(dá)的轉(zhuǎn)速，進(jìn)而調(diào)節(jié)供料器轉(zhuǎn)速。具體來(lái)說(shuō)，通過(guò)改變液壓泵的排量，即單位時(shí)間內(nèi)輸出的液壓油體積，來(lái)調(diào)整進(jìn)入液壓馬達(dá)的油量，油量增加，液壓馬達(dá)轉(zhuǎn)速上升，供料器轉(zhuǎn)速加快；反之則減慢。調(diào)節(jié)液壓系統(tǒng)的壓力也能影響轉(zhuǎn)速，在一定范圍內(nèi)，壓力增大，液壓馬達(dá)的輸出扭矩增大，轉(zhuǎn)速也會(huì)相應(yīng)提高。液壓調(diào)速的優(yōu)點(diǎn)是調(diào)速平穩(wěn)、能提供較大的扭矩，尤其適用于輸送粘性較大或密度不均勻物料的工況，即便負(fù)載發(fā)生變化，也能保持轉(zhuǎn)速的相對(duì)穩(wěn)定。但液壓系統(tǒng)結(jié)構(gòu)相對(duì)復(fù)雜，需要定期維護(hù)，以確保液壓油的清潔度和系統(tǒng)的密封性。

　　Hydraulic speed regulation plays a unique role in situations where high stability is required for speed regulation. The driving device of the rotary feeder adopts a hydraulic motor, which controls the speed of the hydraulic motor by adjusting the flow rate and pressure in the hydraulic system, thereby adjusting the speed of the feeder. Specifically, by changing the displacement of the hydraulic pump, that is, the volume of hydraulic oil output per unit time, the amount of oil entering the hydraulic motor is adjusted. As the oil amount increases, the speed of the hydraulic motor increases, and the speed of the feeder increases; Conversely, it slows down. Adjusting the pressure of the hydraulic system can also affect the speed. Within a certain range, as the pressure increases, the output torque of the hydraulic motor also increases, and the speed will correspondingly increase. The advantages of hydraulic speed regulation are smooth speed regulation and the ability to provide large torque, especially suitable for conveying materials with high viscosity or uneven density. Even if the load changes, the speed can still be relatively stable. However, the hydraulic system structure is relatively complex and requires regular maintenance to ensure the cleanliness of the hydraulic oil and the sealing of the system.

　　還有一種基于傳感器反饋的閉環(huán)調(diào)速方式。在旋轉(zhuǎn)供料器的工作過(guò)程中，安裝在關(guān)鍵位置的傳感器，如轉(zhuǎn)速傳感器、物料流量傳感器等，實(shí)時(shí)采集供料器的轉(zhuǎn)速和物料輸送量數(shù)據(jù)。這些數(shù)據(jù)被傳輸?shù)娇刂葡到y(tǒng)中，與預(yù)先設(shè)定的目標(biāo)值進(jìn)行對(duì)比。當(dāng)實(shí)際值與目標(biāo)值出現(xiàn)偏差時(shí)，控制系統(tǒng)會(huì)根據(jù)偏差大小和方向，自動(dòng)調(diào)整調(diào)節(jié)裝置（如變頻器的輸出頻率、液壓系統(tǒng)的流量等），使供料器轉(zhuǎn)速恢復(fù)到設(shè)定值，從而實(shí)現(xiàn)物料輸送量的精準(zhǔn)控制。這種閉環(huán)調(diào)速方式具有高度的自動(dòng)化和智能化，能夠快速響應(yīng)工況變化，保證物料輸送的穩(wěn)定性和準(zhǔn)確性，在現(xiàn)代化的連續(xù)生產(chǎn)系統(tǒng)中應(yīng)用越來(lái)越廣泛。

　　There is also a closed-loop speed regulation method based on sensor feedback. During the operation of the rotary feeder, sensors installed at critical positions such as speed sensors and material flow sensors collect real-time data on the feeder's speed and material conveying volume. These data are transmitted to the control system and compared with pre-set target values. When there is a deviation between the actual value and the target value, the control system will automatically adjust the adjustment device (such as the output frequency of the frequency converter, the flow rate of the hydraulic system, etc.) according to the magnitude and direction of the deviation, so as to restore the speed of the feeder to the set value, thereby achieving precise control of the material conveying volume. This closed-loop speed regulation method has a high degree of automation and intelligence, which can quickly respond to changes in working conditions, ensure the stability and accuracy of material transportation, and is increasingly widely used in modern continuous production systems.
