Embodiment Construction

[0015] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0016] See figure 1 , The structure of the tension control system based on the numerical value communication mode of the present invention includes PLC, and the unwinding part, the lead-in part, the host part, the lead-out part, and the winding part control part connected with the PLC.

[0017] The unwinding part is provided with an unwinding A-axis inverter 27 and an unwinding B-axis inverter 30. The unwinding B-axis inverter 30 is connected to the B reel through the unwinding B-axis variable frequency motor 29 and its reducer 28, and unwinds The A-axis frequency converter 27 is connected to the A reel through the unwinding A-axis variable frequency motor 26 and its reducer. At the same time, the unwinding diameter detection potentiometer 1 detects the current actual initial diameter of the material film and is directly connected to the unwinding A in an analog...

Abstract

The invention discloses a tension control system based on a numeric quantity communication mode. The system comprises a programmable logic controller (PLC), and a control part for an unreeling part, an introduction part, a host part, an extraction part and a reeling part which are connected with the PLC; an unreeling B shaft frequency converter, an unreeling A shaft frequency converter, an introduction traction frequency converter, a host frequency converter, an extraction traction frequency converter, a reeling A shaft frequency converter and a reeling B shaft frequency converter of all the parts are vector frequency converters; all the vector frequency converters are connected with the PLC through respective numeric quantity communication buses respectively; and the PLC is connected with a human-computer interface through a communication cable. Compared with the prior art, the invention has the advantages that: the tension control system has a high real-time property and high stability, makes data transmitted accurately, and fulfills the aims of saving energy sources and reducing cost at the same time.

Description

Technical field [0001] The invention belongs to the technical field of printing machinery, and is used for the spindle drive control of a unit type gravure printing machine and a compound machine, as well as the automatic tension control of unwinding, introduction, extraction and rewinding, and specifically relates to a tension control based on a numerical value communication mode system. Background technique [0002] Generally, the tension control system of the unit type gravure printing machine and the compound machine adopts analog control, that is, the control program is compiled through PLC to complete the logic control and requirements of the host and the unwinding, introduction, withdrawal, and rewinding The current running speed is given, the corresponding analog signal is output through the PLC analog output module, and then connected to the respective inverter by a two-core shielded wire. The inverter controls the three-phase asynchronous motor according to the analog s...
