Description

A kind of method of quick adjustment shed open angle
Technical field
The present invention relates to weaving technology field, specifically a kind of method of quickly adjustment shed open angle.
Background technique
Adjust that opening process parameter first has to solve in weaving process is exactly warp thread and warp thread, warp thread and heald and warp Friction problem between yarn and reed, in weaving high density kind, this problem can be protruded more, due to warp yarn friction, warp thread Between stick to each other will cause wefting insertion failure, latitude stops number increase, and end breakage also will increase dramatically, while at reed rear It will form small cotton knot to be attached to above warp thread, once cotton balls will be formed on cloth cover by being woven into.So friction problem solution is bad Will result directly in loom efficiency decline, fabric defect increases, such as: looped weft, disconnected warp, cotton balls.
In the prior art by distributing shed open angle come stroke multilayer shed open, to effectively reduce warp thread to every page of heald frame Friction, to guarantee wefting insertion everything goes well with your work to carry out.In the prior art, staff can not directly measure and adjust shed open Angle, rule of thumb can only adjust the angle of shed open indirectly by way of adjusting shed open amount of opening, but according to warp It tests to adjust the problem of causing adjustment portion accurate portion's system, to influence the quality of weaving.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for quickly adjusting shed open angle, for fast and accurately adjusting shed open Angle.
The technical scheme adopted by the invention to solve the technical problem is that: a method of quickly adjustment shed open angle, packet Include following steps,
(1) equation H=2*tan (α/2) * d is obtained according to shed open geometry
α --- shed open angle
H --- stroke of harness frames
D --- fell to heald vertical range；
(2) amount of opening for the heald frame that defined label is X is LX, the traverse of the heald frame marked as X is HX, measure LXAnd HX's Numerical value；
The amount of opening for the heald frame Y that defined label is Y is LY, the traverse of heald frame Y is HY, measure LYAnd HYNumerical value；
(3) point (H was obtainedX,LX) and point (HY,LY) linear equation L=K*H+E
Wherein H --- stroke of harness frames
K --- coefficient
L --- amount of opening
E --- constant；
(4) according to the establishing equation in step (2) and step (3) with marked as longitudinal parameter amount, α is lateral parameter amount, H It is the database of target component amount with L；
(5) according to the technological requirements α numerical value and label is come the numerical value of the L inquired in database；
(6) the L value of corresponding heald frame is adjusted according to query result, to complete the adjusting of shed open angle indirectly.
The beneficial effects of the present invention are: a kind of method of quickly adjustment shed open angle provided by the invention, by establishing simultaneously Amount of opening corresponding to mode quick search shed open angle using database, to realize the quick and precisely system of fore shaft angle Inquiry.
Detailed description of the invention
Fig. 1 is the geometric format figure of shed open；
Fig. 2 is shed open effect picture；
Fig. 3 is shedding mechanism schematic diagram；
In figure: α shed open angle, CD stroke of harness frames, the vertical range of AB fell to heald, 1 cam machine, 2 opening swing arms, 3 Diagonal control arm pullover, 4 diagonal control arms, 5 griffe arm, 6 heald frames hook, 7 long connecting rods.
Specific embodiment
As shown in Figure 1, the geometric format by shed open is analyzed,
TAN (α/2)=CD/ (2*AB)；
CD --- stroke of harness frames H
AB --- fell to heald vertical range d
Then stroke of harness frames and the relational expression at shed open angle can arrange are as follows:
H=2*TAN (α/2) * d formula (1)
α --- shed open angle
H --- stroke of harness frames d-
- fell to heald distance
By formula (1), we can calculate the traverse of this page of heald frame according to the shed open goniometer of certain page of heald frame, wherein fell , can be different due to the variation of fabric variety to the vertical range d of heald, to take Mop rod leading edge to heald convenient for calculating us Vertical range.Distance of the Mop rod leading edge away from first page heald frame is 127mm, and standard heald frame spacing is 12mm, i.e., often toward the next page Vertical range d of the heald frame Mop rod leading edge away from heald increases 12mm.Thus, it is possible to which the shed open angle of every page of heald frame and heald frame are moved Journey is calculated.Table 1 is the corresponding data of shed open angle and stroke of harness frames.
Table 1
Heald frame 26 ° of shed open angle 28 ° of shed open angle 30 ° of shed open angle 32 ° of shed open angle 34 ° of shed open angle 36 ° of shed open angle

10 108.5 117
Determine the relationship of shed open angle and stroke of harness frames, it is also necessary to determine the relationship of L value and stroke of harness frames.Such as Fig. 2 and Shown in Fig. 3, L value is the size being open between 2 upper surface of swing arm and diagonal control arm pullover 3.Whatsoever model in the prior art Cam shedding mechanism or type dobby shedding mechanism are all that opening swing arm 2 is driven to swing by eccentric disc, then pass through diagonal control arm 4 Promotion griffe arm 5 swing, griffe arm 5 drive heald frame hook 6 move up and down, heald frame hook 6 connection heald frames, realize heald frame up and down Movement.Long connecting rod 7 passes motion to other side heald frame hook, such as Fig. 3.It can analyze out L dimension from machine construction principle Relationship with stroke of harness frames is linear relationship, i.e. L=K*H+E, formula (2)
Wherein H --- stroke of harness frames
K --- coefficient
L --- opening is taken measurements
E --- constant
By testing the corresponding data of L value and stroke of harness frames, chart is made.It can be concluded that the chart of L value and stroke of harness frames For an oblique line, the correctness of proof theory analysis.By formula (2) as long as being known that two groups of L dimensions of measurement and H data can To obtain the relational expression of L dimension Yu stroke of harness frames H.By the way that the L dimension of certain brand cam machine and the pass of stroke of harness frames is calculated Be formula are as follows: H=-0.4*L+119, thus formula we obtain stroke of harness frames required for technique by adjustable L dimension.
It, can will be between shed open angle, stroke of harness frames and shed open angle three by above-mentioned formula (1) and formula (2) Corresponding relationship is decided, and the corresponding relationship table 2 of three is come out, and only needs to look into when adjusting opening process parameter Table.
Table 2
By taking JC60XJC60X173X156 forges line kind as an example, using winged threading method, sequence of gaiting is 1,3,5,2,4, then The shed open differential seat angle of the adjacent heald frames of page two of sequence of gaiting is tuned into 2 degree, then the adjustment of shed open angle should be as shown in table 3 below:
Table 3
Heald frame 1 2 3 4 5
Shed open angle 36° 30° 34° 28° 32°
Because according to this sequence warp thread of page 1,3 two of gaiting be it is adjacent together, other heald frames.In this way It distributes shed open angle and guarantees that per two adjacent warp thread shed open differential seat angles be all 2 degree, can effectively reduce friction.According to table 3 Technique requires to table look-up 2, and L dimension, which is adjusted to the corresponding size of table 2, can be realized technique requirement.
Calculation method of the invention is suitable for the cam or type dobby shedding mechanism that different model loom is equipped with different model, when When loom model, cam machine or dobbies model difference, the data of Tables 1 and 2 can be different.
