AI Technical Summary
In existing technologies, placing the drive screw in the middle of the conveyor affects the quality of X-ray images. The dual-motor drive method is costly, has a high failure rate, and poor width control accuracy.
The conveyor width automatic adjustment device, driven by a single motor, uses a combination of trapezoidal lead screws and synchronous belts for transmission. A single width adjustment drive motor drives two trapezoidal lead screws to adjust the width synchronously. A constant force spring and steel wire coil apply constant tension to the adjustable track of the conveyor, eliminating the gap between the trapezoidal lead screws and the slider.
It improves X-ray image quality, reduces costs and failure rates, while enhancing motion accuracy and stability, offering high space utilization, low cost, and stable functionality.
