Background

An encoder is a device that compiles, converts, and formats signals (e.g., bitstreams) or data into a form of signals that can be communicated, transmitted, and stored. Encoders convert angular or linear displacements, called codewheels, into electrical signals, called coderulers. The encoder can be divided into a contact type and a non-contact type according to a reading mode; encoders can be classified into an incremental type and an absolute type according to their operation principles. The incremental encoder converts displacement into periodic electrical signals, and then converts the electrical signals into counting pulses, and the number of the pulses is used for expressing the magnitude of the displacement. Each position of the absolute encoder corresponds to a determined digital code, and its representation is therefore dependent only on the start and end positions of the measurement, and not on the intermediate course of the measurement, in the application of the encoder, machines for processing and finishing printed sheets into printed finished products, namely printing machines, are widely applied, mainly in an automatic material receiving machine part on the printing machines, the encoders on the existing automatic material receiving machines are mostly directly and hard connected by adopting an encoder rotating shaft and a motor rotating shaft, because the mechanical equipment inevitably generates vibration in the running process, the rotary shaft of the encoder is driven to generate vibration, the precise parts in the encoder can be damaged after a long time, and in addition, the axial direction of the rotary shaft of the motor can be changed at some times, and the encoder passes through screw fixed connection at equipment, causes the axial difference, not only can produce measuring error, can damage the encoder moreover.
