Glass fiber impregnating compound preparation automatic control system

Abstract

The invention relates to the glass fiber impregnating compound preparation automatic control technical field, and specifically relates to a glass fiber impregnating compound preparation automatic control system comprising a controller; the controller is externally connected with an analog input output module; the input port of the analog input output module is externally connected with a viscositysensor, an oil temperature sensor, a water temperature sensor, a raw material flowmeter and a hot water flowmeter; the viscosity sensor is externally connected with a frequency meter; the input end of a controller switch value I / O module is externally connected with a water level upper limit detector, a water level lower limit detector, and a frequency transition annunciator; the output end of the controller switch value I / O module is externally connected with a raw material valve, an agitator motor, a steam valve, a hot water valve, a normal temperature water valve and a tap water valve. Thesystem can precisely control the key technique parameters, thus effectively preventing artificial operations from affecting the production stability, improving the impregnating compound preparation quality, reducing the worker laboring intensity, reducing operator quantity, reducing cost, and increasing gains.

Description

technical field [0001] The invention relates to the technical field of glass fiber automatic control, in particular to an automatic control system for preparing a glass fiber sizing agent. Background technique [0002] In the production of glass fiber, it is necessary to use a sizing agent to treat the surface of the fiber precursor to make it have good textile and mechanical properties. In the production of sizing agent, some links basically adopt automatic preparation and control, but there are still many links that are operated manually. The key factors in the process of sizing agent preparation process, such as the addition of raw materials, temperature control, and water addition Parameters such as time control and turning point judgment are mainly completed by the operator's experience, which ultimately leads to unstable product quality. [0003] Due to the influence of human factors, the production of sizing agent is unstable, the quality is poor, and the waste of ra...

In the production of sizing agent, some links basically adopt automatic preparation and control, but there are still many links that are operated manually. The key factors in the process of sizing agent preparation process, such as the addition of raw materials, temperature control, and water addition Parameters such as time control and turning point judgment are mainly completed by the operator's experience, which ultimately leads to unstable product quality

[0003] Due to the influence of human factors, the production of sizing agent is unstable, the quality is poor, and the waste of raw materials is large, which directly leads to the loss of economic benefits
