Description

Can beat the Warp tying machines head of two kinks

The utility model is a kind of improvement of Warp tying machines head, can play two kinks.

" weaving is learned " p246-252 that textile industry publishing house publishes in June, 1988 discloses a kind of name and has been called the automatic Warp tying machines of ZK712 type cutter formula, and it is made up of frame and head (see figure 1) two parts, and the main effect of head is to finish the organizine knotting.Because every dozen one of this bartacker knot knotting cutter only takes two turns, first lap forms ring formation earlier, and second circle promptly forms knot, so this traditional round knot is as if meeting into fiber or the higher deficiency of knot rate then can appear taking off in the left-hand lay line.

The utility model is in order to overcome the deficiency of above-mentioned prior art, and a kind of two kinks of beating are provided, and when being used for synthetic fiber or left-hand lay line, takes off the Warp tying machines head that the knot rate descends greatly.

The utility model is implemented by the following technical programs.

This Warp tying machines head comprises leasing mechanism, knotting mechanism and advancement and coordination mechanism, and knotting mechanism comprises that cam and action are subjected to the left elastic rod of its control, knotting cutter tooth wheel and the driving gear that is engaged with, and its improvement is:

1) engagement of driving gear and knotting cutter tooth wheel is than being adjusted into 3: 1 by 2: 1;

2) right elastic rod mechanism is installed on the contact pin bearing on knotting cutter right side;

3) left elastic rod, right elastic rod and knotting cutter are by timing figure motion shown in Figure 5;

4) line AP and BP and primary meridian angle α and β are not less than blind angle (establishing the subpoint of primary meridian on knotting swivel moving axis is P, and knotting cutter left and right sides warp outermost point is A and B) separately.Angle α and β allow greater than blind angle, only make warp put more some morely outward, but if less than blind angle warp maybe can not be hooked, or can not Cheng Jie etc. misoperation.The size at angle α and the pairing blind angle of β is relevant to the distance of two elastic rods, the knife-edge of tiing a knot shape size etc. with the knotting cutter, can obtain by experiment under the guidance of timing figure.

The utility model is through as above improving, because the knotting cutter turns around more, becomes that knot also more turns round a circle, can get new knot---and two kinks so can be applicable to synthetic fiber or left-hand lay line preferably, make and take off the knot rate and descend greatly.

Fig. 7 is the utility model embodiment 2 structural representations.

Below in conjunction with embodiment the utility model is further described.The Warp tying machines head comprises leasing mechanism, knotting mechanism and advancement and coordination mechanism, become the knot process mainly being rotated under left elastic rod 2-1 and right elastic rod 3-1 cooperate by the knotting cutter 1-1 of knotting mechanism and finish, thereby the embodiment (see figure 2) adopts following improvement:

1) one every dozen two kink knotting cuttves need 3 circles (1080 °) of revolution clockwise, and the engagement of driving gear 4 and knotting cutter tooth wheel 1-2 is than being adjusted into 3: 1 for this reason, and former every circle edge of a knife action remains unchanged;

2) the incompatible needs of beating new knot of the former hook of tying tight so lower fork lappet (dotted line is represented) is removed, form left elastic rod 2-1, and its action is installed in the left cam 2-2 control (Fig. 3) on the transverse axis 5;

3) on the contact pin bearing (near knotting cutter one side) on knotting cutter right side, right elastic rod 3 (Fig. 4) of mechanism are installed newly, the right elastic rod 3-1 of this mechanism is installed on the transition plate 3-6 by pin 3-4, and transition plate is fixed on the contact pin bearing 3-2 in the form of sheets; The end of back-moving spring 3-3 connects right elastic rod, and the other end is fixed on the contact pin bearing; Right cam 3-5 is installed on the transverse axis 5, controls the action of right elastic rod 3-1;

4) above-mentioned left elastic rod 2-1, right elastic rod 3-1 and knotting cutter 1-1 press Fig. 5 timing figure motion;

5) control line AP and BP and primary meridian angle α ≮ 26 ° 34 ' and β ≮ 22 ° 37 '.

The dynamic description of present embodiment:

The embodiment initial state, knotting 0 ° on cutter (vertically downward), the double warp level is horizontal (sees that Fig. 6-A), left and right sides elastic rod all is in 0 station below the knotting cutter.The knotting cutter is when 0 ° goes to 30 °, and left elastic rod is put to I station outside 0 station, promotes warp left side section and roughly becomes a level angle (being not less than 26 ° 34 ') with initial state to outermost point A; The knotting cutter hooks warp in the time of 90 °; The knotting cutter is when 150 ° go to 180 °, right elastic rod is put outside 0 station to the right section of I station promotion warp to outermost point B and is roughly become a level angle (being not less than 22 ° 37 ') with initial state, warp becomes a ring formation, finishes shape shown in Fig. 6-B, and after this warp cutter head outer rim of always tiing a knot is tangled; The knotting cutter is when 360 ° go to 390 °, and right elastic rod is retracted into 0 station from the I station and treats next circulation, and the right section of warp is rollback thereupon; The knotting cutter is when 540 ° go to 660 °, and left elastic rod retreats to 0 station in the I station, and warp left side section is rollback thereupon; The knotting cutter goes to 810 ° of processes from 660 °, left side elastic rod retreats to the II station in 0 station, warp left side section is subjected to the tractive of the hook of tying tight of left elastic rod, finish that blade is clamped line end, cut off waste silk, knocking over, one-tenth knot (see Fig. 6-E ,-F), with a series of actions such as knot tighten up; The knotting cutter is when 810 ° go to 900 °, and left elastic rod is back to 0 station from the II station and treats next circulation.

The present embodiment action data is roughly:

Left and right sides elastic rod to the distance of the cutter of tiing a knot is 12mm.Establishing the left elastic rod fork heart again is L, and it is R that right elastic rod pushes away the limit, and this moment, both were from the distance H at center separately _L, H _RConcern with knotting swivel angle position: 0 ° of-30 ° of-540 ° of-660 ° of-720 ° of-810 ° of-900 ° of-1080 ° of H of swivel angle _L(mm) 14 → 20-20 → 14 → 8 →-12 → 14-14; 0 ° of-150 ° of-180 ° of-360 ° of-390 ° of-1080 ° of H of swivel angle _R(mm) 10-10 → 16-16 → 10-10.

α angle ≮ 26 ° 34 ', β angle ≮ 22 ° 37 '.

After left and right sides elastic rod is determined to the position of the cutter of tiing a knot,, can design left and right sides cam and left and right sides elastic rod easily in fact according to concrete data and timing figure.

Present embodiment adopts 150D, and Z1500 sth. made by twisting/rice warp takes off the knot rate and reduces to from original 40% and be not more than 2%.

The utility model can be got two creative contributions of turning round new knot and be, and the one, the knotting cutter turns around more, and then knot also more turns round one and enclose into new knot; The 2nd, can periodically be in outermost end A and B by two a cam elastic rod mechanism controls knotting cutter left side and right warp.Therefore except embodiment 1, realize that second technical scheme is also a lot.

Embodiment 2.Right elastic rod of the present utility model mechanism can also be a structure as shown in Figure 7.The right elastic rod shape of this mechanism is with left elastic rod 2-1, and all the other are constant.A β reaches requirement as long as the described right elastic rod of this example mechanism is designed to make the right section of warp angle.
