Study on the Control of the Fixation Device for the Dehulling of Thick Shell

The processing process of thick shell mussel mainly involves classification, cleaning, processing and peeling, sorting and packaging, which is low in efficiency and high in labor intensity. In order to improve the processing efficiency of thickshelled mussel, an economical and environmentally friendly fixation device for thick-shelled mussel was proposed based on the difficulties in the processing and dehulling of thick-shelled mussel. According to the thick shell mussel off half shell fixed device working principle arrangement control flow chart, combined with the specific control requirements for THE SELECTION of PLC, draw the main circuit control diagram, I/O distribution table and program ladder diagram, parallel PLC completed pipeline PLC control ladder diagram program design, and online simulation test on the software. The results show that the structure design can theoretically meet the requirements of automatic half-shell removal of thick shell mussels, and the design of the control system conforms to the action sequence control of the pipeline, and the port runs normally without any error. The signal transmitted by the control system was transmitted to each link to ensure the automatic processing of the whole device. The design of the control system laid a foundation for the practical production and application of thick shell mussel.
