Hot roller temperature control device for producing superfine denier nylon 66

Abstract

The invention discloses a hot roller temperature control device for superfine denier nylon 66 production, which comprises a roller body, a controller and a roller body temperature monitoring module, and is characterized in that the roller body temperature monitoring module comprises an infrared temperature sensor arranged above the roller body, and the infrared temperature sensor is used for detecting the heating temperature of the surface of the roller body; a detection signal is sequentially sent to the filter amplification circuit and the ripple elimination circuit for conditioning and then sent to the controller, and a detection feedback regulation circuit is further arranged at the output end of the filter amplification circuit and used for forming stable regulation in the filter amplification stage; the controller adjusts the heating temperature of the roller body in real time by controlling the heater in the roller body, so that the melting temperature of the hot roller is always in the optimal range value, it is guaranteed that fibers are evenly heated in the rapid production process, and the production quality is improved.

Description

technical field [0001] The invention relates to the technical field of nylon production equipment, in particular to a heating roller temperature control device for the production of ultra-fine denier nylon 66. Background technique [0002] Nylon 66 is polyhexamethylene adipamide, which has high fatigue resistance and rigidity, good heat resistance, low friction coefficient, good wear resistance, and stable chemical properties. The ultra-fine denier nylon 66 is modified to improve the process parameters of ultra-fine fibers. During the spinning and forming process, the original nylon chips are transported to the drying tower for solid-phase drying and viscosity increase, so that they can reach the high-viscosity chips required for spinning. The dried slices are subjected to humidity control treatment to stabilize the moisture content to 700PPM, and then the processed slices are melted and extruded through a screw extruder, and then transported to the melt conveying process us...

AI Technical Summary

Problems solved by technology

In the process of hot roller melting and feeding, due to the defects of low sensitivity and slow response speed of the existing hot roller temperature control device, and the temperature detection process is also easily disturbed by environmental factors, the hot roller often occurs during the rapid production process. The heating temperature does not reach the process standard range, resulting in poor control of the melting temperature of the hot roller, which affects the production quality of ultra-fine denier nylon 66
