Problems solved by technology

The feeding amount fluctuates greatly, which is very unfavorable to the grinding, and it is difficult to control the quality of the product
In addition, various states of the system, such as blocked machine state, empty grinding state, raw material shortage, etc., cannot be identified, and corresponding control and treatment of various states cannot be made, which often results in substandard products

Abstract

The invention which relates to an automatic feeding controller of a milling system provides an automatic feeding controller based on the programming control of PLC (programmable controller). A technical scheme of the invention is that the automatic feeding controller of the milling system comprises the PLC, a text display, a communication cable, a host intelligent ammeter, a fan intelligent ammeter, a feeding spiral frequency converter, an expanded relay, an alarm and a frequency converter manual control switch. The controller which can accurately control the feeding amount of the whole milling production system, automatically cope with and process various abnormal states of the whole milling production system, effectively reduce waste and defective products and improve the production efficiency is suitable for milling automation control systems of powder processing enterprises.

Description

technical field [0001] The invention relates to an automatic feeding control device for a milling system, in particular to an automatic feeding control device based on PLC programming control. Background technique [0002] The original automatic feeding device of the calcium carbonate grinding system is composed of the host intelligent ammeter, the fan intelligent ammeter, the feeding frequency converter, and the manual control switch of the frequency converter, such as figure 2 As shown, the automatic feeding device uses the main engine and some contacts of the internal relay of the smart ammeter of the fan to be connected in series, and then a manual control switch SA is connected in series to control the jog terminal X2 of the feeding screw inverter, so that the operating frequency of the inverter is at The "normal frequency" (such as set to 25HZ) and the "jog frequency" (such as set to 45HZ) are constantly changing, so as to achieve the purpose of automatic control of th...
