Fully automatic high-speed air-jet loom in wide size

Abstract

The present invention discloses a fully-automatic high-speed wide air-jet loom. It includes fully-automatic control system, beating mechanism, double fabric pressing-on roller and back beam. The hardware of the above-mentioned fully-automatic control system includes main control plate, electronic warp let-off plate and liquid crystal touch screen, on the main control plate, electronic warp let-off plate and liquid crystal touch screen are respectively set CPU, between main control plate and electronic warp let-off plate they are connected by means of I / O and bus extension interface, the communication between main control plate and liquid crystal touch screen can be implemented by means of serial interface, the above-mentioned CPU adopts 16-bit computer on a chip and utilizes on -line programmable unit and storage unit whose capacity is above 128 KB. The described beating mechanism is a six bar linkage beating mechanism.

Description

Technical field [0001] The present invention relates to an air jet loom. Background technique [0002] Air-jet loom in the prior art, technical characteristics and existing problems of some related aspects are as follows: [0003] One is: the core hardware of its control system mainly includes programmable controller PLC. The programmable controller includes a programmable module, an output module, an input module, and an analog input module. The programmable modules are connected by serial communication, and the automatic control of the air-jet loom is realized through the internal program of the PLC and the external control circuit. The electrical structure of this fully automatic control system is relatively simple, but the response speed of the system is slow, and the adaptability of fabric varieties is poor, so it cannot be well applied to high-speed and wide-width air-jet looms. The main reason is that the main function of PLC is logic control, that is, switch value ...

AI Technical Summary

Problems solved by technology

[0006] The first main task of the present invention is to overcome the technical defects of the existing air-jet loom control system in the prior art, which adopts the traditional programmable logic controller PLC and cannot well meet the development requirements of the automatic control of high-speed and wide-width air-jet looms, and provides a new type of full-width air-jet loom Automatic control system, the system adopts new core control components and new combination methods; the second is to provide a new type of weft beating mechanism, which can make the swing motion of the beating shaft have a longer dwell time in the rear dead center, and has a large weft insertion angle. , smoother weft insertion and other advantages; the combination of the two can not only better meet the automatic control requirements of high-speed and wide-width air-jet looms, but also meet the mechanical requirements of high-speed and wide-width air-jet looms for weft insertion
