Embodiment Construction
[0015] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0016] A shaftless tracking driving method for the auxiliary machine of a web flexible printing machine is implemented on the basis of the following device, see figure 1 , The measuring encoder 2 is installed on the rotating part of the main machine to measure the rotation of the main machine drive shaft 1. The measuring encoder 2 output is connected to the auxiliary machine servo controller 3; the auxiliary machine servo controller 3 is composed of a servo power part 31 and a servo control part 32, The servo power part 31 is externally connected with 380V three-phase AC power supply and 24V DC power supply, as well as an external auxiliary machine servo motor 4. The servo control part 32 has a program socket 6 and a servo serial port signal control line interface 7 for signal transmission, and a measurement code The output line of the auxiliary machine 2 is co...

The invention discloses an auxiliary machine shaftless tracking driving method of a roll paper flexible printing machine. The auxiliary machine shaftless tracking driving method is achieved by outputting the driving control to an auxiliary machine servo motor through an auxiliary machine servo controller, and the work mode is a phase synchronous mode. In the phase synchronous mode, the auxiliary machine servo controller controls the auxiliary machine servo motor to carry out shaftless tracking driving; a measurement encoder mounted on a main machine is defined as a virtual main shaft; the auxiliary servo motor of a matched auxiliary machine unit serves as a slave shaft; and the auxiliary machine controller carries out operation on the real-time data from the measurement encoder and from an auxiliary machine servo feedback encoder, and outputs the processed data to control the operation of the auxiliary machine servo motor so as to make the roller surface linear velocity of the main machine equal to that of the auxiliary machine unit. The method can be used for achieving the synchronous tracking driving of the shaft main machine and the matched shaftless auxiliary machine, omittingthe needs of a larger number of mechanical parts, omitting the mechanical shaft connection with the main machine and improving the mechanical accuracy of the matched machine unit of the machine.
Description
Technical field [0001] The invention relates to a shaftless tracking driving method for auxiliary machines of a web flexible printing machine. Background technique [0002] The existing web flexible printing machine includes a main unit and an auxiliary unit. The auxiliary unit generally includes a printing unit, a screen unit, a coating UV unit, etc. The connection between these units and the main unit usually adopts a shaft connection, and the shaft connection It is not only necessary to consider the power matching of the driving motor of the original main engine, but also to consider the consistency of the surface linear speed of the main paper feed roller and the auxiliary paper feed roller, that is, the matching coupling of the gear ratio. As a result, the mechanical structure of the entire printing press system is huge and complicated, and the installation is complicated. Summary of the invention [0003] The purpose of the present invention is to provide a shaftless tr...
