When you consider the range of feed machines on the market today, the advantages of servo feeding machines stand out starkly, especially when it comes to feed step distance. Servo feeding machines provide unparalleled benefits over pneumatic and roller feeding machines in this regard.
Unleashing Multistage Feeding Capabilities
Firstly, servo feeding machines introduce the power of multi-step distance settings, a feature that enhances the scope of multistage feeding. Secondly, the feed step distance of a servo feeding machine isn’t bound by the platform of the machine. In fact, it allows for flexible settings between 0 and 10 meters. Given the stringent limitations on each model step distance imposed by pneumatic and roller feeders, servo feeding machines hence exhibit a wider usability, carving a niche among clients in the manufacturing industry.
However, standard servo feeding machines don’t come without their own set of challenges.
Feeding Accuracy Challenges of Standard Servo Feeding Machines
Standard servo feeding machines experience certain hiccups with feeding accuracy when the feed step distance gets unreasonably lengthy. This limitation is present regardless of whether the model is pneumatic or mechanical relaxation type. Neither can guarantee high feeding accuracy. With a feed step distance of 1000mm, feeding accuracy often exceeds ±0.5mm, a precision rate significantly lacking for high-precision production.
The reason behind this is the transmission principle used by standard servo feeding machines. These machines depend mostly on servo motors in combination with synchronous pulley wheels and timing belts to drive the feeding roller. This results in precise step-by-step feeding. However, the gear ratio achieved by the synchronous wheel is minimal, about 1:4, necessitating an increase in servo motor power for larger power requirements. Furthermore, the use of timing belt transmission might lead to belt slack, negatively impacting the precision of step-by-step feeding. If the belt tension is increased, belt breakage may ensue, thus making it challenging to ensure feeding precision and stability during long-step distance feeding.
The Rise of High-Torque Direct-Drive Servo Feeder
To rectify this, our team has specifically engineered a high-torque direct-drive servo feeder, tailored for long-step, high-precision feeding. This innovation swaps out the synchronous pulley transmission with a transmission method that employs a servo motor and a gear reducer to drive the feed roller. This effectively overcomes the power drive and stability deficiencies of existing feeders, culminating in a high transmission rate, smooth operation, and minimal noise. At a feed step distance of 1000mm, this feeder delivers an accuracy of ±0.15mm, promising superior feeding precision and stability.
Structural Details of the High-Torque Direct-Drive Servo Feeder
This direct-drive servo feeder comprises a main feed machine frame, feed rollers positioned on this frame, a servo motor beneath the feed rollers, an inlet material support frame, and an outlet material support frame. In addition, it features a gear reducer that aligns with the direction of the servo motor output shaft. This servo motor links to the feed roller via the reducer. The gear reducer is equipped with a horizontal quality reliability hole and a vertical second hole. It connects directly to the servo motor via the quality reliability hole and the servo motor output shaft, and to the feed roller via the second hole and the feed roller input shaft. This design ensures precise transmission. Its compact structure offers stability and reliability, guaranteeing high precision for long-step feeding.
