The working principle of the variable twist angle blending mechanism is as follows:
in the working process, the second motor 14 is in a braking state, so the twist angle control barrel 9 can be regarded as a fixed part, the first motor 16 drives the central rotating shaft 36, the five tow material rollers 31, the five a godet wheels 29 and the five groups of twist angle conversion units 30 integrally rotate along the central axis 38, the universal balls 27 of the ball universal ball seats 25 of the twist angle conversion units 30 all roll on the conical surface 7 of the twist angle control barrel 9, all the twist angles x are always a constant value under the constraint of the conical surface 7 of the twist angle control barrel 9, and meanwhile, the winding roller 37 is controlled to rotate to wind; then the fiber filaments 2 led out from each filament bundle roller 31 sequentially cross over the godet wheel 29 and the twist angle conversion unit 30 in front a, then are plied and twisted with other four fiber filaments 2 in the initial twisting part 3 to form a plied yarn 1, and the plied yarn 1 after being twisted passes through the twisting channel 5 and then is wound on a winding roller 37; so that the wind-up roll 37 continuously winds and stores the plied yarn 1 formed by plying and twisting five filaments of aramid fiber filament, viscose fiber filament, wool fiber filament, modacrylic fiber filament and conductive fiber filament;
when the lay length of the plied yarn 1 is to be increased to obtain the long-lay-plied yarn 1.2, the winding speed of the winding roller 37 and the rotation speed of the central rotating shaft 36 are controlled again, and the size of the lay angle x is reduced as follows:
at this time, the second motor 14 is controlled to rotate the twist angle control barrel 9, under the screw drive between the transmission sleeve 19 and the twist angle control barrel 9, the twist angle control barrel 9 is displaced forward a distance along the axial direction, so that each universal ball 27 rolls on the conical surface 7 with smaller inner diameter, thereby the b godet wheels 28 on all the twist angle conversion units 30 are closer to the central axis 38, each spring 22 is automatically compressed a distance, at the same time, the twisting barrel 4 is correspondingly displaced leftward a distance, each b godet wheel 28 moves close to the central axis 38, and each twist angle x is synchronously reduced on the basis of the forward movement of the twisting barrel 4, thereby achieving the effect of changing the twist angle x.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention, and such modifications and adaptations are intended to be within the scope of the invention.
