Automatic preparation method of moistening agent

Abstract

The invention relates to an automatic preparation method of a sizing agent, which is based on a computer control system as well as a weighing device and an automatic control valve that are connected with the computer control system. The computer control system is provided with a display screen and an indicator light, and various preparation steps and formulas of the sizing agent are all stored in a database of the computer control system. The preparation method comprises the following steps of accessing the computer control system, choosing a formula, weighting raw materials, dispersing and diluting the raw materials, and mixing. The computer control system is provided with a server, an operator station terminal, a printer, the display screen, the indicator light, the Ethernet and a programmable controller; and the weighing device consists of a small material weighting balance, a bulk material weighting tank, a low storage tank weighting instrument, a preparation tank weighting instrument and a medium material weighting platform balance. The server is connected with the display screen, the indicator light and the Ethernet, the operator station terminal is connected with the printer and the Ethernet, and the programmable controller is connected with the Ethernet, the small material weighting balance, the bulk material weighting tank, the low storage tank weighting instrument, a stirrer, the automatic control valve, the preparation tank weighting instrument and the medium material weighting platform balance. The method reduces the labor strength of workers and guarantees the feeding sequence and weighting precision.

Description

Technical field: [0001] The invention relates to a method for automatically preparing a glass fiber sizing agent. Background technique: [0002] At present, the preparation of sizing agent in the glass fiber industry adopts a traditional preparation process, and all steps in the preparation process are manually operated by workers. There are many disadvantages in this process: 1. The correct feeding sequence cannot be guaranteed. The preparation of a wetting agent needs to weigh a variety of raw materials, some as many as a dozen, and these raw materials must be added strictly in a certain order. Reversing the order will cause chemical reactions between raw materials and affect the quality of the wetting agent. Manual operation often leads to confusion in the order in which operators add materials. ②The labor intensity of workers is high. During the preparation process, some raw materials need to be weighed in relatively large quantities, some as many as three or four hun...

Problems solved by technology

There are many disadvantages in this process: ① cannot guarantee the correct feeding sequence

The preparation of a wetting agent needs to weigh a variety of raw materials, some as many as a dozen, and these raw materials must be added strictly in a certain order. Reversing the order will cause chemical reactions between raw materials and affect the quality of the wetting agent.

Manual operation often leads to confusion in the order of the operator's feeding

②The labor intensity of workers is high

Relying on manual weighing is very labor-intensive

③ Weighing accuracy cannot be guaranteed

The weighing of raw materials in each step is judged subjectively by the operator, which cannot guarantee the weighing accuracy well

④It is easy to make mistakes in nesting

The process of discharging the prepared wetting agent into the designated container is also manually opened by the operator to open the discharge valve. A slight negligence will cause the valve to open wrongly and cause the wetting agent to be confused.
