Design of Chip Compressor System Based on PLC

针对传统的木片压缩机自动化程度低,压实度低、运输效率低等问题,设计了一种基于PLC的木片压缩机系统,该系统为机电液一体化设备。首先,对机械结构进行了设计,尤其是输送装置的设计;其次,采用液压作为传动系统,利用传感器技术、行程开关、电磁阀等实现了木片压缩机的自动运料、压缩、出料等功能;最后,采用PLC作为系统的控制核心,分析与设计了PLC选型、I/O口分配、硬件接线和软件编程。该系统增加了木片的压实度,节约了木片的生产成本,提高了木片的运输效率,自动化程度高,工作可靠。

Aiming at the problems of low automation degree, low compaction degree and low transportation efficiency, a wood chip compressor system based on PLC is designed, and the system is an electromechanical integration equipment. Firstly, it designs the mechanical structure, and especially designs the conveying device. Secondly, using the hydraulic pressure as a transmission system, in addition, the functions of automatic transport, compression, pushing the chip and so on are realized by using sensor technology, stroke switch and solenoid valve. Finally, using PLC as the control core of the system, analyzing and designing the PLC selection, I/O port allocation, hardware wiring and software programming. The system increases the compactness of the wood chips, saves the cost of the production of the wood chips, and improves the transport efficiency of the wood chips, which make the high automation and reliable work of system.
