为了解决人造板胶黏剂制备过程中人工取样测定胶黏剂粘度效率低和数据滞后的问题,设计一种新型扭矩式胶黏剂在线黏度监测器。该粘度监测器由传感器、直流稳压器和黏度表三部分组成。传感器主要由扭矩弹簧和可变电阻器组成,安装在反应釜搅拌轴的减速器和搅拌器之间,直流稳压器为传感器提供稳定的12V稳压直流电源。工作时,随着胶黏剂粘度的增加,扭矩弹簧的扭角增大,使可变电阻的阻值减少,电路中电流增大,然后将电流表值换算成相应的粘度值通过表盘示出,实现对胶黏剂生产过程中的粘度在线监测。该扭矩式胶黏剂在线黏度监测器结构简单,制造成本低,维护方便,检测精度高,经济实用,适合中小型人造板企业及胶黏剂专业生产企业使用。
In order to solve the problem of low viscosity and lag data of artificial adhesive in the process of artificial board adhesive preparation, a new type of online viscosity monitor of torque adhesive was designed. The viscosity monitor by the sensor, DC regulator and viscosity meter of three parts. The sensor is mainly composed of a torsion spring and a variable resistor. It is installed between the retarder agitator shaft reducer and the agitator, and the DC regulator provides a stable 12V regulated DC power supply to the sensor. Work, with the viscosity of the adhesive increases, the torsion angle of the torsion spring increases, the resistance of the variable resistor decreases, the current in the circuit increases, and then the ammeter value is converted to the corresponding viscosity value shown by the dial, To achieve the viscosity of the adhesive production process online monitoring. The torque adhesive on-line viscosity monitor has the advantages of simple structure, low manufacturing cost, convenient maintenance, high testing precision, economy and practicability, and is suitable for small and medium-sized wood-based panel manufacturers and adhesive manufacturers.
