Abstract

The invention discloses a redundancy self-locking drive control device for a frequency converter of cigarette equipment, which has the main design concept that a second relay, a contactor and a time relay are matched with a first relay to provide an output cut-off mechanism for the frequency converter, and specifically, the contactor is connected between the frequency converter and a motor; a second relay coil is connected with the frequency converter, a time relay coil and a first relay coil are connected with an operation signal source in parallel, and a specific normally-open switch of a first relay is connected with a power supply and a contactor coil. And the second relay is connected in series with the normally open switch of the time relay and then connected in parallel with the specific normally open switch of the first relay to form a cut-off circuit with a self-locking mechanism. According to the invention, safe and reliable disconnection of the contactor can be ensured, so that the access between the motor and the frequency converter can be safely and reliably cut off in a specific scene, and particularly, a safe redundancy design is formed by the time relay and the second relay.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing equipment, in particular to a redundant self-locking drive control device for frequency converters of cigarette equipment. Background technique [0002] Cigarette equipment needs a large number of frequency converters to drive motors used in various scenarios. Therefore, the failure rate of a large number of frequency converters used by cigarette companies will be relatively high, and when the frequency converter fails, it will directly It is related to the operation status of the corresponding equipment motor. [0003] At present, in practical applications, there have been many problems that the motor on the corresponding cigarette equipment cannot be stopped in time due to the failure of the frequency converter. After analysis, it is mainly due to the failure of the above-mentioned components to reliably disconnect the path between the output terminal of the frequency converter and the mot...
