Extrusion extruder operating parameter automatic matching control system and control method

Abstract

The invention discloses an extrusion extruder operating parameter automatic matching control system and control method. The control system comprises an MES system, an extrusion device and a PLC controller of the extrusion device. Standard production process parameters of extruded products are integrated by the MES system. A high-precision width measuring instrument is arranged on an extrusion linkage line. The high-precision width measuring instrument is arranged at the position which is 1.5-2 m away from a machine head of the extrusion linkage line so as to detect the widths of the extruded products in real time and feed the widths back to the PLC controller. The linkage line speed is adjusted by the PLC controller based on the received real-time measurement data and the obtained standardproduction process parameters. According to the scheme, various operating production data are directly integrated in combination with the enterprise MES system, through communication connection withthe PLC controller, automatic uploading and downloading of operating parameters are achieved, in addition, when the operating parameters are matched, the screw rotation speed and the linkage line speed are automatically matched, the defects that traditional manual operating parameter adjustment is low in efficiency and high in rejection rate are effectively overcome, and the control system and control method have extremely high popularization and economic value.

Description

technical field [0001] The invention belongs to the field of extruder extrusion production in the rubber industry, and in particular relates to an automatic matching control system and control method for operation parameters of an extrusion extruder. Background technique [0002] In the prior art, although the extrusion operation parameters of the extruder have solidified more production operation condition parameters in terms of program design, such as temperature control and operation condition transmission, these parameters do not play a substantial role in actual operation. The control function requires manual intervention to match multiple parameters to effectively ensure the stability of the extruded parts; and under actual production conditions, due to the need to deal with multiple production specifications, when the extrusion production specifications alternate, the operator needs to target the corresponding production specifications. , manually enter the correspond...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to solve the defects of poor extrusion dimensional stability, low efficiency and high error rate caused by manual input of standard parameters and manual participation in extrusion parameter matching in the production process of extruded parts of existing extruders. An automatic matching control system and control method for extruder operation parameters is proposed. Based on the connection between the existing MES and the extrusion equipment PLC, the production operation parameters can be realized without manual intervention, and automatic production can be started with one button.
