Automatic cleaning system for nozzles of fully automatic intelligent spinning machines

Abstract

The invention provides an automatic cleaning system for a full-automatic intelligent spinning machine nozzle. The automatic cleaning system comprises an air supply system and an automatic control system, wherein the automatic control system is connected with the air supply system and controls the same to supply air to a cleaning nozzle and an N2 sprayer in the air supply system according to the time sequence requirement so as to complete the cleaning of the whole cleaning nozzle and the yarn pre-twisting performed by the whole N2 sprayer. The automatic cleaning system has the advantages that the pressure of the air conveyed to the cleaning nozzle can be adjusted according to different fiber lengths and varieties and process requirements, a factory air source is pressurized and stabilized through a pressurizing pump, the air pressure range of the cleaning nozzle is adjusted through a pressure adjusting valve, high-precision control is achieved, the air pressure control of the cleaning nozzle is high in precision and good in consistency, the adjustable range of the air pressure of the cleaning nozzle is wide, a control module ECU is used to perform time sequence control on a nozzle control electromagnetic valve, high control precision is achieved, time sequence control precision is + / -1ms, time sequence intersection of two air paths is avoided, and yarn spraying yield is increased effectively.

[0002] Fully automatic intelligent (air-jet vortex) spinning machine is a highly automated and intelligent spinning equipment that integrates the functions of roving frame, spinning frame and automatic winder, and is at the leading level of contemporary spinning technology; broken yarn splicing Accurate, reliable, and clean nozzles of the spinning unit of the fully automatic intelligent (air-jet vortex) spinning machine are conducive to improving the pass rate of one-time spraying of the fully automatic intelligent (air-jet vortex) spinning machine and improving machine efficiency. One of the key technologies of the fully automatic intelligent spinning machine; at present, most of the domestic use to stop feeding cotton after the yarn is broken and prolong the time of spraying the nozzle of the spinning unit to achieve the purpose of cleaning the nozzle, but in the actual spinning production process, there are The following problems: first, it often takes a long time to wait for the nozzle to be cleaned, and there are secondary pollution defects; second, the problem of low air injection pressure and unstable air injection pressure; The problem of different pressure requirements during cleaning, the defect that the nozzle is not clean before yarn spraying, the problem that the air pressure of the nozzle cleaning cannot be adjusted, the qualified rate of the first yarn output from the nozzle is reduced, and the machine efficiency is low, etc. Therefore, it is necessary to propose an improvement
