Control system for express bag sealing and gluing machine

Abstract

The invention relates to a control system for an express bag sealing and gluing machine. The system comprises a servo motor unit consisting of a plurality of servo motors, an asynchronous motor unit consisting of a plurality of asynchronous motors and a host motor, a PLC controller, an AD / DA module and a signal acquisition module. The servo motors in the servo motor unit is driven by a plurality of corresponding servo drivers, the asynchronous motor unit is driven by a plurality of corresponding frequency converters and a host frequency converter corresponding to the host motor, and the PLC sends pulse signals to the servo drivers to achieve accurate fixed-length control over the servo motor unit. The PLC receives a data signal acquired by the signal acquisition module through the AD / DA module, outputs the data signal to the corresponding frequency converter after operation of the PLC, and drives the corresponding asynchronous motor to realize accurate closed-loop signal control afteramplification of the frequency converter; and the PLC makes the host frequency converter at a set speed through a communication protocol realize automatic acceleration and deceleration actions of thehost motor.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to a control system for an express bag sealing and gluing machine. Background technique [0002] The courier bag for mailing paper documents needs to be sealed and stored. The courier bag sealing glue machine is to coat the seal of the courier bag with a destructive adhesive that can be opened at any time. When making it, it is necessary to seal the courier bag. Glue on the release film, and then attach the glued release film to the seal of the courier bag, so that the seal is firmly pasted and can be disassembled and destructive, and then cut into independent courier bags and then unloaded. [0003] In the actual use of the existing courier bag sealing and gluing machine, if the courier bags of different specifications are sealed and glued, workers need to adjust the motors on the various parts of the sealing and gluing machine according to the length or width of the courier bag. To ...

[0003] In the actual use of the existing courier bag sealing and gluing machine, if the courier bags of different specifications are sealed and glued, workers need to adjust the motors on the various parts of the sealing and gluing machine according to the length or width of the courier bag. To adapt to the courier bag of this specification, but this method is too cumbersome to operate, and there are many manual adjustment steps, and each part needs to be precisely matched with each other for multiple times of debugging before it can be put into production. If a part is wrongly debugged, the running speed of the whole machine will be reduced. , the failure rate increased
