An electric servo control method and system for a refractory brick press feeder

Abstract

The embodiment of the invention discloses an electric servo control method for a firebrick pressing skip car, and the method comprises the steps that man-machine interaction equipment obtains a target set value of the skip car, and transmitting the target set value to a controller; the controller generates an initial instruction according to the target set value, and outputting the initial instruction to a servo controller; the servo controller generates a control instruction according to the initial instruction, and outputs the control instruction to a servo motor so as to control the rotating speed of the servo motor; the servo motor rotates according to the control instruction; a coder detects a feedback signal in real time and enables the feedback signal to be fed back to the servo controller; and the servo controller enables the feedback signal to be compared with the initial instruction, and adjusts the outputted control instruction. The embodiment of the invention also discloses an electric servo control system for the firebrick pressing skip car. The system provided by the invention replaces a conventional hydraulic control system, effectively simplifies a hydraulic oil path, employs a closed loop mode, improves the control precision, and improves the system response speed and stability.

Description

technical field [0001] The invention relates to the field of ceramic equipment manufacturing, in particular to an electric servo control method for a refractory brick press feeder trolley and an electric servo control system for a refractory brick press feeder trolley. Background technique [0002] Such as figure 1 As shown, the existing refractory brick press material truck is usually controlled by a hydraulic power control system. Specifically, the hydraulic power control system uses an oil motor 1' as a power device, and the speed of the oil motor 1' controls the flow rate through a proportional valve 2' to adjust; the front end of the proportional valve 2' is provided with an oil filter 3' and a pressure gauge 5', wherein the oil filter 3' is used to filter impurities in the oil, and the pressure gauge 5' is used to observe the valve of the proportional valve 2' At the same time, there is a cartridge valve 9' at the front end of the proportional valve 2'. The cartridge ...

AI Technical Summary

Problems solved by technology

[0004] (1) The structure is too complex and easily affected by the oil state;

[0005] (2) Oil leakage will inevitably occur in the oil circuit, which is easy to pollute the environment;

[0006] (3) The maintenance is inconvenient, the replacement parts need to be depressurized and vacuumed, and the oil is easy to cause pollution during maintenance;

[0007] (4) The positioning accuracy is not high enough;

[0008] (5) Low overload capacity;

[0009] (6) Slow response, prone to overshoot
