Multi-arm tap 4-1, steel wire rope 4-2, first turns to wheels 4-3, Triangular Arm group 4-4, be and use former machine part, former machine effect is that look is selected in control, select the two kinds of states that are controlled to be of look, choose: multi-arm tap 4-1 moves after the first steel wire rope 4-2 is spurred, do not choose: the first steel wire rope 4-2 reach resets, these two kinds of states (we below will with choosing and not choosing to describe 2 kinds of duties that become filling density controlling organization 4) are reflected to us and become in the filling density controlling organization 4 to be exactly, choose: multi-arm tap 4-1 will be by the first steel wire rope 4-2, Triangular Arm group 4-4, make on the second steel wire rope 4-6 and move, the second steel wire rope 4-6 will control on the stay cord 4-11 and move, because the control stay cord 4-11 other end is connected with separator 4-8, separator 4-8 also will turn over an angle counterclockwise, multi-arm tap 4-1 does not reset when choosing, resetting of it will allow the second steel wire rope 4-6 to reset under the effect of wire rope spring 4-7, division board 4-8-1 is reset to the position that spacing stay cord 4-9 allows counterclockwise under the effect of separator back-moving spring 4-10, separator turns over an angle clockwise; The effect of spacing stay cord 4-9 is quite important, this is because the second steel wire rope 4-6 is choosing and do not choosing traverse in the transfer process, the needs that swing between separator 4-8 turnover fastener 2-1 and the close gear wheel 3-1, spacing stay cord 4-9 restriction separator 4-8 reset angle, reduced control stay cord 4-11 to also having avoided the impact of the second steel wire rope 4-6 high acceleration to separator 4-8 the action time of separator 4-8, made division board 4-8-1 turnover steadily.
Referring to shown in Figure 7, tell about the setting principle and the adjustment method that become filling density.
At first several characteristics and concept are said: 1) the support number of teeth: refer to that each batches the cycle tooth figure place that (hunting period that is equal to swing mechanism 1-1), the close gear wheel 3-1 of fastener 2-1 racking turned over; 2) the support number of teeth only may be integer, and for fear of the few support of the many supports of fastener, the pendulum angle of fastener 2-1 is for setting the support number of teeth+0.5 tooth position; 3) the common filling density size on the decision machine of the close gear wheel 3-1 number of teeth and the support number of teeth, that is to say that same filling density is not unique for the selection of the close gear wheel 3-1 number of teeth and the support number of teeth, be that each batches cycle fastener 2-1 and drives the size that angle that close gear wheel 3-1 turns over has determined filling density in essence, the filling density size is batched the angular dimension that close gear wheel 3-1 of cycle turns over each and is inversely proportional to.
With the close gear wheel number of teeth=60, the support number of teeth=4 are example, and the debugging and possibility situation that become filling density are described.
1) by adjusting mandrel component 1-6 position, make fastener 2-1 support tooth head swing position be: shown in the G0# RADIAL of limit on the right-right-hand limit position, shown in the G5# RADIAL of limit on the left position.These adjustment are routine operation, are 45 pieces/inch fabric with obtaining in the machine filling density;
2) band by adjusting triangle arm group 4-4 colludes screw rod 4-4-4 in becoming filling density controlling organization 4, butterfly silk 4-4-5 position is alignd the G1# RADIAL of the guiding surface 4-8-2 root of separator 4-8, like this in the situation that even fastener 2-1 swing situation is constant, because a tooth is isolated dish 4-8 isolation, the support number of teeth becomes 3 by 4, and it is 60 pieces/inch that this state operation will obtain in the machine filling density; If in like manner transferring to guiding surface 4-8-2 root aligns with the G2# RADIAL, it is 90 pieces/inch in the machine filling density, align with the 3# RADIAL, 180 pieces/inch of machine filling densities, it is to be noted that the guiding surface 4-8-2 root of separator 4-8 must not surpass the G4# RADIAL, if will cause supportting the number of teeth above the G4# RADIAL is zero, filling density becomes infinity, and this is unallowed.With regard to this example, we can obtain 45 and 60,45 and 90, any 2 kinds of filling densities pairing of 45 and 180 becomes filling density and weaves, if higher filling density and the ratio that hangs down filling density are defined as multiple proportions, take low filling density as benchmark, select suitable pickwheel number and the non-support number of teeth of attitude of choosing to cooperate the selected state support number of teeth, can realize that multiple proportions is that two kinds of any regularities of distribution of filling density of 1.15-6 are weaved;
3) further can also be by increasing by the first steel wire rope 4-2, the second steel wire rope 4-6, steel wire rope back-moving spring 4-7, control stay cord 4-11, realize how different filling densities on same cloth arbitrarily the regularity of distribution weave, how a kind of filling density distributes arbitrarily for one group of every increase, and is easy as increasing the broadwise number of colours.
