Fully automatic cutting and forming intelligent control system for brick and tile industry

Abstract

The invention relates to a fully automatic cutting and forming intelligent control system for a brick and tile industry. The system comprises an extruder operation control system consisting of an extruder control device and an extruder program control part. The extruder program control part comprises a main program, a parameter setting sub program, a data storage sub program, an extruder pressure PID control sub program, an extruder current PID control sub program, and an extruder production control sub program. The intelligent control system further comprises an extruder slitting self-diagnosis system. The invention can accurate control the extruding pressure of an extruder, is small in fluctuation range of the extruding pressure, high in forming quality, and good in production adaptability to different products, also has a self-diagnosis function and an alarm function, and can carry out self-diagnosis analysis of reasons why a program cannot continue to operate and display the analysis result and fault solution on a human-machine interface. In addition, when a slitting steel wire breaks, the diagnosis system can automatically alarm and stop the operation of an extruder host.

Description

technical field [0001] The invention relates to an intelligent control system for fully automatic extrusion cutting molding used in the brick and tile industry. Background technique [0002] The fully automatic extrusion and cutting equipment for the brick and tile industry is composed of an extruder, a strip cutter and a billet cutter. Cutting into long strips, the blank cutting machine is used to cut long strips of mud into mud blanks of required size. [0003] The two-stage vacuum extruder is an important mechanical equipment in the brick production process. The extrusion pressure is the core parameter of the two-stage vacuum extruder, which is directly related to the quality of the product. In the existing vacuum extruder equipment, the extrusion pressure is roughly adjusted by manually distributing water in the upper stage of the vacuum extruder. Due to the inaccurate manual adjustment, the extrusion pressure of the extruder will fluctuate greatly. And the control of ...
