Embodiment Construction

[0010] Below in conjunction with accompanying drawing, novel control system of the present invention is described in further detail:

[0011] Such as figure 2 In the internal mixer formula management and process control system shown, the touch screen is connected to the storage and control module of the PLC. The formula data and process data are stored in the PLC, and are displayed by the display module through the touch screen. The control system is as follows: figure 1 As shown, under the condition that the internal mixer of the equipment meets the production conditions, first enter the automatic operation unit through the touch screen, where 200 formulas are stored, select the production formula from the formula data by operating the touch screen, and start the automatic operation after the relevant operating conditions are met. The equipment executes according to the parameters set in the formula and in accordance with the process sequence, and stores the corresponding pr...

Abstract

The invention relates to an internal mixer, in particular to a formulation management and process control system of the internal mixer. A touch screen is connected with a storage and control module of a PLC; formulation data and process data are stored in the PLC, and are displayed through the touch screen by a display module, as shown in figure 1: as indicated in a control cabinet figure, first, an automatic operation unit is entered through the touch screen; a production formula is selected from the formulation data; automatic operation is started after initial conditions of related equipment operation are fulfilled; the equipment executes according to the parameter set in the formula and process sequence, and stores related record of process data in the PLC; after a circulation is finished, the circulation conditions are determined whether to be fulfilled or not, if so, the equipment goes on operating, if not, the equipment stop production, and a motor is stopped. The invention abandons the prior computer professional software, completely adopts an electric device, changes programming thought, and realizes related functions by electric technology. The internal mixer is convenient for maintaining, has large data storage capacity, and can fulfill the requirement of users.

Description

1. Technical field [0001] The invention relates to an internal mixer, in particular to a formula and a process control system of the internal mixer. 2. Background technology [0002] At present, the control system of the internal mixer used for rubber mixing in the rubber (plastic) industry requires special computer software to complete the formula management and process data monitoring and recording, and the logic control requires a programmable logic controller (hereinafter referred to as PLC) . The investment in the factory is large, the hardware needs to be equipped with industrial computers, the software needs to develop professional software, and professionals are needed for programming and later maintenance. 3. Contents of the invention [0003] The purpose of the control system of the present invention is to overcome the above-mentioned disadvantages and provide a formula management and process control system for internal mixers, which is simple, convenient, pract...
