The FA432 roving machine developed by Shanxi Jingwei Heli Machinery Manufacturing Co., Ltd. passed the mechanical appraisal recently.
The FA432 roving frame is a new type of roving frame designed and developed on the basis of FA431 and FA436 roving frames. The utility model is characterized in that the upper and lower iron cannons, the forming device and the lower dragon dam resetting device are eliminated, and the two sets of frequency conversion control system and the coded monitoring device are used together with a pair of electromagnetic clutches to complete the winding and forming functions, thereby simplifying the mechanical structure of the roving frame and improving the electromechanical The degree of integration reduces costs and improves spinning speed and quality.
After the empty car was run, the prototype was subjected to 800 rev / min and 1000 rev / min constant speed and speed reduction. The two batches of head and tail ingots and the front and rear rows of six ingots were operated. . The cotton C40 was spun and both were well formed.
