Engineering plastic processing device and glass fiber content control method

Abstract

The invention aims to provide an engineering plastic processing device and a glass fiber content control method. The engineering plastic processing device comprises a double-screw extruder with a discharge hole in the front end, a particle main ingredient weigh-feeding mechanism and a glass fiber weigh-feeding mechanism located above the double-screw extruder, and a controller. The double-screw extruder comprises a cylinder, two screw rods arranged in the cylinder, and a motor electrically connected with the controller; and a particle main ingredient feed inlet corresponding to the particle main ingredient weigh-feeding mechanism, a frustum-shaped glass fiber guiding port connected with the cylinder and corresponding to the glass fiber weigh-feeding mechanism, and a vacuum orifice are sequentially arranged on the cylinder from back to front. According to the engineering plastic processing device, the addition amount of glass fiber is stable, the error is less, the accuracy in detectingthe glass fiber content in engineering plastic is higher, and the glass fiber content can be monitored and adjusted in real time.

Description

technical field [0001] The invention relates to the field of engineering plastics manufacturing, in particular to an engineering plastics processing device and a glass fiber content control method. Background technique [0002] In engineering plastics, glass fiber is a commonly used reinforcement and modification raw material; the change of glass fiber content in engineering plastics directly affects the mechanical properties of engineering plastics, so the control of glass fiber content is particularly important in the production process of engineering plastics; traditional engineering plastics In the plastic production process, the amount of glass fiber added is unstable and the error is large; the glass fiber content in engineering plastics is calculated by the weight of a few glass fibers entering the twin-screw extruder per unit time combined with the amount of pellets added , or calculate the glass fiber content in engineering plastics after measuring the ash content i...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the instability of glass fiber addition and large errors in the current production process of engineering plastics. The weight of a few glass fibers entering the twin-screw extruder per unit time combined with the addition of pellets Calculation of the glass fiber content in engineering plastics, or calculate the glass fiber content in engineering plastics after measuring the ash in engineering plastics by burning method, the detection accuracy of glass fiber content in engineering plastics is low, and the detection time is too long. Insufficient of real-time monitoring, provide a kind of engineering plastics processing device and glass fiber content control that can monitor and adjust glass fiber content in real time, with stable glass fiber addition, small error, high accuracy in detecting glass fiber content in engineering plastics method
