As shown in fig. 2-3, the distance B1 or B2 between the center of the front roller 2-1 or the small condensing spinning roller 2-2 and the top surface of the keel 7, the distance B1 or B2 are set to be 506-546 mm according to bobbins 5 with different lengths L, wherein the distance B2 is determined according to the distance B1 because the relative positions of the front roller 2-1 and the small condensing spinning roller 2-2 are fixed, and vice versa.
The yarn guide plate 4 is provided with a spinning starting position according to the length L of bobbins 5 with different specifications, so that the distance from the bottom of a yarn guide hook 4-1 to the top end face of the bobbin 5 is C which is twice the diameter of the small end of the bobbin 5, and meanwhile, the spinning length D from a front roller 2-1 or a compact spinning small roller 2-2 to the yarn guide hook 4-1 can be shortened, the height h of a twisting triangular area cannot be increased, and the spinning angle alpha and the yarn length D which are summarized by traditional optimization are kept.

To reduce the angle of wrap γ, the spinning angle α, which is determined to be 45 ° in the design of the spinning frame, can be reduced or the roller stand inclination, which is limited by the increase in the wrap arc of the sliver on the thread-guide 4-1 and the resulting increase in the twist trap; secondly, twist trap is increased, twist distribution on the yarn is gradually reduced from a steel wire ring to a front roller 2-1 or a small concentrated spinning roller 2-2 jaw, because twist generated by the rotation of the steel wire ring around a steel collar is firstly transmitted to an air ring and then transmitted to the front roller 2-1 or the small concentrated spinning roller 2-2 jaw through a yarn guide hook 4-1, due to the hysteresis phenomenon of twist transmission and the large twist trap effect of the yarn guide hook 4-1, the twist of a spinning section is gradually reduced, particularly the twist near the meshing line of the front roller 2-1 or the small concentrated spinning roller 2-2 is the minimum, and therefore the control on fibers at the edge of a twisting triangular area is insufficient, and the quality of finished yarn is influenced.
As shown in the figures 2-4, the height of the spinning twisting triangular area is also related to the front impulse X of the front roller leather roller 2-3 meshing line during ring spinning or the front impulse X of the compact spinning leather roller 2-4 during compact spinning, and the larger the front impulse X is in a certain range, the smaller the surrounding arc 12 of the jaw output fiber strip on the roller is, so that the height h of the twisting triangular area is reduced.

the aggregation spinning method is characterized in that an aggregation spinning negative pressure system is added, an aggregation spinning small roller (2-2) is installed in a holding groove of a special-shaped tube seat (12), and the aggregation spinning small roller (2-2) and an aggregation spinning leather roller (2-4) form an aggregation spinning small roller drafting pair, and specifically comprises the following steps:
step 1': determining the spinning starting position of the yarn guide plate (4) according to the length of the bobbin (5), thereby determining the spinning length D from the front roller (2-1) to the yarn guide hook (4-1) and the height h of the twisting triangular area, and keeping the spinning angle alpha and the yarn length D which are summarized in the traditional optimization;
step 2': winding the roving strips meeting the requirements of specification and weight on a roving bobbin, feeding the roving strips through a yarn guide by tight pressing between a rear roller drafting pair, then pressing and passing through a middle roller drafting pair, then pressing and passing through a front roller drafting pair, and finally pressing and passing out through a small gathering and spinning roller drafting pair;
step 3': the motor of the spinning machine is started, yarn is discharged, the yarn passes through a yarn guide hook (4-1), and finally, the yarn is wound on a bobbin (5) arranged on a spindle (6);
step 4': under the action of a gathering spinning negative pressure system, hairiness on the spun yarn is adsorbed in the same direction, the spun yarn is twisted from bottom to top by the speed difference between the rotation of the steel wire ring and the rotation of the bobbin (5), the hairiness is coated in the yarn at the same time of twisting, the strength of the yarn is increased, wherein the twist is the spindle rotation speed/the linear speed of the front roller, and the winding forming of the gathering spinning yarn on the bobbin (5) is realized.
