Embodiment Construction

[0020] figure 1 A schematic diagram of a material delivery system for a stirring pot according to an embodiment of the present invention is shown. refer to figure 1 As shown, the material feeding system includes a host computer 11 , a programmable logic controller (PLC) 12 , an input unit 13 , a material valve 21 , weighing sensors 41 , 42 and a weighing instrument 40 . The host computer 11 is used as a delivery window for a production order. On the host computer 11, the name of the material to be dropped and the amount of material to be put in can be input and set, and this parameter will be passed to the PLC12. The PLC 12 and the upper computer 11 can be connected through an Ethernet network cable, and communicate based on the TCP / IP protocol. The input unit 13 is used to receive various process control parameters input by the operator, and input them to the PLC 12 . In one embodiment, the input unit 13 can be a touch screen. The input unit 13 and the PLC 12 can be conne...

Abstract

The invention relates to an automatic control method and a device for stirring pot material feeding. The method comprises the following steps: receiving a material name and a set material feeding amount; continuously opening a material valve leading to a stirring pot to feed a material to the stirring pot; continuously detecting the difference valve between an actual material feeding amount and the set material feeding amount; when the difference valve reaches a precise feeding start threshold value, intermittently turning on the material valve to continue to feed the material to the stirring pot; and when the difference valve reaches a feeding-off start threshold value, turning off the material valve to stop feeding the material to the stirring pot;.

Description

technical field [0001] The invention relates to an automatic control of the daily chemical industry, in particular to an automatic control method and device for feeding materials into a stirring pot. Background technique [0002] Traditionally, in the daily chemical industry, for the feeding of stand-alone equipment, it is first manually weighed, and then manually fed into the mixing pot. In this case, basically the accuracy of feeding can be guaranteed. But occasionally there will be manual weighing errors, or the problem of wrong feeding. In recent years, with the increase of labor cost of domestic daily chemical enterprises and higher requirements for product quality, automated production equipment has gradually replaced traditional stand-alone equipment. However, in automatic production equipment, how to solve the problem of ensuring the accuracy of material feeding in the process of automatic feeding through pipeline transportation is a common problem.
