Automatic silk reeling machine steam pipeline device and its control technology

Abstract

The invention discloses a steam pipeline device of an automatic silk reeling machine and a control process of the steam pipeline device. The steam pipeline device comprises an inner perforated pipe, an outer perforated pipe, a blind pipe, a steam manifold and a steam main valve which are arranged at an end groping basin, wherein each of the inner perforated pipe and the outer perforated pipe comprises two perforated pipe sections controlling steam supply quantity. The control process includes: real-time temperature is collected through a temperature sensor and compared with set temperature, the openness of an electric valve is calculated through the valve openness feedback signal of the electric valve and PID operation, and a PLC outputs to control the openness of the electric valve so asto adjust pipeline steam pressure. The steam pipeline device has the advantages that total steam quantity is controlled through the sectioned design structure, the requirements that the temperature ofthe high temperature area of the end groping basin is located in the required high temperature interval and the temperature of the low temperature area of the end groping basin is located in the required low temperature interval can be satisfied effectively, and accordingly the end groping hot water in the end groping basin can meet the end groping temperature condition.

Description

technical field [0001] The invention relates to the field of locomotive threading technology and the like, in particular to an automatic silk reeling locomotive threading steam pipeline device and its control process. Background technique [0002] The automatic reeling machine is the key equipment for raw silk processing, which draws out cocoon silk and assembles it into raw silk. Raw silk production is a traditional advantageous project in my country, and the automatic silk reeling machine produced in my country represents the most advanced level in the world. The automatic silk reeling machine is composed of a locomotive and a body. Generally, one silk reeling machine has 400 threads for the body, and each group is equipped with a locomotive (a cable threading mechanism) at both ends. At present, my country's relatively advanced automatic silk reeling machine is the leader of Hangzhou Textile Machinery Factory. [0003] Thread silkworm cocoons (including boiled cocoons, ...

Problems solved by technology

[0019] The purpose of the present invention is to design the automatic silk reeling locomotive head threading steam pipeline device and its control process. The steam pipeline device adopts a segmented design structure to control the total amount of steam to solve the problem of high temperature in the prior art. The shortcoming that the temperature difference between the low temperature zone and the low temperature zone is too small is not easy to thread, which can effectively meet the temperature of the high temperature zone of the Suoxu pot in the required high temperature range, and the low temperature zone can also be in the required low temperature range, so that the cable in the Suoxu pot Xutang can meet the temperature conditions of Suoxu; the control process combines various technologies such as physical data acquisition and electrical control to automatically control its equipment and process data, so as to improve the accuracy of temperature control and improve the quality of equipment and equipment.
