Replacement device of spinning hot roller heating and driving controller

Abstract

The invention discloses a replacement device of a spinning hot roller heating and driving controller. The replacement device comprises a process setting computer and a main control board which are electrically connected with each other. The replacement device further comprises a first controller used for simulating communication between a frequency converter and the main control board and a secondcontroller used for simulating communication between a temperature controller and the main control board. The second controller is electrically connected with the main control board; and the first controller is electrically connected with the process setting computer and the main control board. The replacement device of the spinning hot roller heating and driving controller is low in cost and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of chemical fiber processing, in particular to a heating and driving controller replacement device for spinning hot rollers. Background technique [0002] There is a polyester yarn production line imported from abroad that is specially used for spinning polyester yarn. Each part of the production line includes two hot rollers, two spindle rollers and one traverse roller, and the five rollers are driven by five special frequency converters. The temperature of the two hot rollers is controlled by two dedicated thermostats, such as figure 1 shown. The setting parameters of these frequency converters and temperature controllers are all input by the process setting computer, and then communicated to the main control board of each part through the communication line, and then obtained by the communication transmission of the main control board. Among them, five frequency converters are connected to one communica...

AI Technical Summary

Problems solved by technology

[0003] 1. A large number of frequency converters and temperature controllers for heat rollers do not participate in the actual control but must be retained, which increases the use of frequency converters and temperature controllers and increases the cost of equipment

[0004] 2. Due to the presence of oil mist in the surrounding environment of the electrical control cabinet, these heat roller inverters and temperature controllers may fail due to oil mist or other reasons, thus increasing the workload of electrical instrument maintenance workers
