The Implementation of a Conveying System Based on Synchronous Belt Drive in CT Security Equipment

Computed tomography security inspection equipment for luggage and package is aimed at spiral scan and spot scan test for luggage and package. The conveying system is an important part of the equipment. The operation stability and accuracy of the conveying system will affect the quality of scanning image and image acquisition of contraband. The need to research and develop a specific conveying system for computed tomography security equipment and several technical difficulties to be solved are described. A new type of conveying system with a built-in servo motor, a synchronous belt to drive, a controlled feed speed, a high positioning accuracy and the modular design method, which is designed to solve the difficulties mentioned above, is discussed briefly. The conveying system supports the integral design of the CT security inspection instrument well and ensures the smooth realization of the entire system function.
