Wireless control system of composite material belt rolling main engine

Abstract

The invention discloses a wireless control system of a composite material belt rolling main engine. The wireless control system comprises a wireless Ethernet SCALANCE system based on a PROFINET industrial bus standard, a programmable logic controller (PLC), a servo driver with an industrial Ethernet interface, an absolute value encoder of an industrial Ethernet Profinet communication interface and a cell phone or a tablet computer which is used as a man-machine operation interface. The wireless control system takes PROFINET as an industrial network communication standard and the PROFINET is fused with the SCALANCE system to form a wireless industrial network; a driving part and a height control part are fused to form a whole body, so that the reliability and the compatibility of the system are improved; and the difficulties that the driving part and the height control part cannot be uniformly and remotely controlled, a factory main engine cannot be uniformly and comprehensively controlled, the heights of a heating region, a cooling region and a middle lifting roller cannot be accurately controlled and the operation of an operator is not convenient, which trouble the industry for a plurality of years, are perfectly solved.

Description

Technical field: [0001] The invention relates to a wireless control system for a composite material belt rolling host, belonging to the field of composite material production machinery. Background technique: [0002] In terms of speed control of the belt rolling machine used for the usual resin composite sheet or plate strip or PP honeycomb panel, the operator needs to approach the belt rolling machine when the speed is adjusted, directly through the operation panel of the frequency converter to the upper transmission of the rolling machine The main roller and the lower drive main roller are independently controlled by open-loop speed, and then the actual line speed is calculated according to the frequency displayed on the inverter panel, and the current line speed cannot be visually checked. And because the machines in production are operated at close range, noise, dust, and the transmission mechanism of the main engine all bring hidden dangers to the safety of operators. ...

Problems solved by technology

[0002] In terms of speed control of the belt rolling machine used for the usual resin composite sheet or plate strip or PP honeycomb panel, the operator needs to approach the belt rolling machine when the speed is adjusted, directly through the operation panel of the frequency converter to the upper transmission of the rolling machine The main roller and the lower drive main roller are independently controlled by open-loop speed, and then the actual line speed is calculated according to the frequency displayed on the inverter panel, and the current line speed cannot be visually checked

And because the machines in production are operated at close range, noise, dust, and the transmission mechanism of the main engine all bring hidden dangers to the safety of operators

[0003] In terms of height control, the height control part of the heating zone, cooling zone, and intermediate lifting roller completely relies on the operator to observe the stroke with the naked eye, and cannot accurately control the height of the rise and fall

Even if a man-machine interface (i.e. touch screen) is installed on the host for observation, it will bring the same security problems

[0004] At the same time, the multiple belt rolling hosts in the workshop operate independently and cannot form an operating system. It is necessary to go to each host separately to perform related operations

[0005] All of the above will bring inconvenience and potential safety hazards to on-site operations, affect production efficiency and cause operational errors

The speed difference generated by the upper and lower drive rollers will also affect the surface of the composite material, reducing the yield and causing great losses to the composite material manufacturer
