The line sending method of the utility model the following steps are included:
Step 1, referring in Fig. 7, dotted line is baseline in figure, and the solid line across upper thread needle 4 is upper thread, and upper thread needle 4 is in most
High point, baseline pulling needle 6 are located at left end and in 4 inferoanteriors of upper thread needle；Upper thread passes through the upper thread hole of upper thread needle 4,4 back of upper thread needle
Tensile force of the upper thread by cloth on upper thread plate 3, baseline turns left the baseline hole in baseline pulling needle 6 from the right side, baseline pulling needle 6
Tensile force of the baseline on the left side by cloth on upper thread plate 3, at this point, left side baseline and baseline pulling needle 6, which form one, is located at upper thread
First baseline V-type space angle 31 of 4 lower left of needle.
Step 2, referring to Fig. 8~9, when upper thread needle 4 moves down with upper thread, baseline pulling needle 6 is turned right with baseline
It swings, upper thread needle 4 hauls the upper thread V-type space angle 32 that upper thread needle 4 passes through lower section baseline down and baseline pulling needle 6 is formed.When
When upper thread needle 4 reaches lower end extreme position, baseline pulling needle 6 reaches extreme right position simultaneously.At this point, referring to Fig. 9, upper thread needle 4
A V-type space angle is formed with the upper thread on the left of it, 6 point of a knife of baseline pulling needle is located at face in the right of upper thread needle 4, left side baseline
The front of line needle 4 and its front upper thread.
Step 3, referring to Figure 10, when baseline pulling needle 6 hauls baseline to when the movement of 4 rear of upper thread needle, drive shaft drives simultaneously
Locating rod 10 is mobile, and locating rod 10 and fixed link 9 are matched for clamping tightly upper thread or gear in upper thread side.At this point, 6 point of a knife of baseline pulling needle
It hauls baseline and winds upper thread needle 4 and its front upper thread from front to back, 6 point of a knife of baseline pulling needle passes through upper thread and upper thread needle 4 in c figure
In the upper thread V-type space angle 32 that 4 rear of upper thread needle is formed.
Step 4 is formed with upper thread needle 4 at 4 rear of upper thread needle referring to Figure 11 when 6 point of a knife of baseline pulling needle enters back upper thread
Upper thread V-type space angle 32 when, upper thread needle 4 moves up, and upper thread is wrapped in the lower section of baseline pulling needle 6 not with upper thread needle 4
It moves up.When baseline pulling needle 6 moves to left side extreme position, left side baseline and baseline pulling needle 6 form one and are located at upper thread needle 4
Second baseline V-type space angle 33 of lower left, upper thread needle 4 reach highest point.
Step 5, referring to Figure 12, fabric is moved a certain distance, and baseline pulling needle 6 moves to the right, while upper thread needle 4 is in face
The opposite fabric in material upside moves a certain distance is passed down through fabric once more, in the upper thread in baseline pulling needle 6 from baseline pulling needle 6
It is detached from front wires needle 4 and is inserted into the second baseline V type space angle 33, when baseline pulling needle 6 swings to the right extreme position, baseline is dialled
Upper thread on needle 6 is detached from from baseline pulling needle 6, but the upper thread needle 4 due to landing again at this time drives upper thread to be inserted into the second bottom
In line V-type space angle 33, so the upper thread to fall off in baseline pulling needle 6 is twined with the baseline at the second baseline V-type space angle 33
Around cyclization, that and so on completes upper thread and baseline is wound chain.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
