The update of our heavy duty apron feeder is essential due to the outdated technology used in the previous version. In comparison to similar equipment abroad, it has several shortcomings such as material surging, deviation issues, low efficiency, and high energy consumption. These drawbacks hinder its ability to meet the demands of the market economy. Consequently, we are compelled by objective factors to consider replacing this equipment. Developing a new heavy duty apron feeder is now a priority for us. To achieve this goal, we have taken into account both domestic design and manufacturing experience while also incorporating imported technology through digestion and absorption processes. The result is a new type of equipment that surpasses its predecessor in terms of innovation and advanced technologies implemented throughout each component.
One notable improvement lies in the driving device of the new heavy duty apron feeder. It utilizes a linear planetary series combined reducer dynamic instead of relying on parallel shaft reducers and open gear transmissions like those found in older models. This upgrade not only reduces weight but also enhances mechanical ratio while occupying less space than before. Additionally, by installing the drive device on the spindle with open gear transmission as its base, we have eliminated structural compactness issues present in previous designs where installation errors directly affected drive device accuracy.
Furthermore, our new apron feeder adopts a single point floating suspension structure along with an external locking disc that does not connect to the spindle (as shown in Figure 1). This innovative approach ensures smooth operation with minimal noise levels while greatly facilitating installation, disassembly, and maintenance procedures.
