Picking motion filling insertion way, efficiency and the operability the problems such as, while guarantee during wefting insertion not with yarn intervention and provide one
A biggish weft tension.
A kind of picking motion of multi-layer cylinder loom, including wefting insertion fixed plate, wefting insertion shuttle, even circumferential are distributed in wefting insertion
N group transmission device and n shuttle position-limited wheel in fixed plate, wefting insertion fixed plate are spliced by way of m block combines, with drop
Low manufacture difficulty, wefting insertion fixed plate can also be an entirety, the blank parts stayed among it be used for beating reed plate, and
The place that yarn passes through, wefting insertion shuttle is engaged with n gear of n group transmission device by arc-shaped rack and is driven, thus edge
Circumferencial direction completes wefting insertion action.In the initial state, low speed rotation is started by n stepper motor, according to the letter of sensor
Number initial origin position is found, then resynchronizes high speed rotation, arc-shaped rack is successfully precisely nibbled with other gears
It closes.Wefting insertion shuttle does not interfere with the harness motion of warp thread when moving in a circle simultaneously, after warp thread first does harness motion,
Wefting insertion shuttle is then passed through opening, finally completes beating-up, and whole process does not stop.For the feelings for avoiding the occurrence of tooth butt or latch
Condition will adjust the position of transmission device and shuttle position-limited wheel, shuttle position-limited wheel and transmission device and be limited to wefting insertion shuttle admittedly
In fixed tracks, wefting insertion action is completed using the form circular motion of rack-and-pinion, full-automatic wefting insertion is realized, solves
The problem of existing craft filling insertion rate is slow, low efficiency, also optimizes the shortcomings that circular weaving machine cannot be used in multi-layer cylinder loom.
Further, for the ease of the automation of realization wefting insertion, every group of transmission device includes being arranged in wefting insertion fixed plate
Fixing seat, stepper motor, gear, motor fixing plate, idler wheel, in order to make each gear that can find origin at the beginning, need
Identical location hole, location hole fixed screw, by sensor sensing screw position, so that it is determined that tooth are found on each gear
A recess has been opened in the position of wheel, fixing seat lower end, and sensor setting is easy to disassemble with the position of induction gear in indent,
And efficiently use space, not with yarn intervention.
Further, in order to wefting insertion shuttle can swimmingly be run, the motor fixing plate of fixed stepper motor with it is solid
Waist-shaped hole is opened in the place of reservation connection, convenient for adjusting.When installation, idler wheel and the limit bottom plate under arc-shaped rack were tight before this
Closely connected conjunction, then adjustment gear again, keep gear and arc-shaped rack much smoother engage.
Further, in order to which high efficiency completes wefting insertion action and reaches good weave effect, wefting insertion shuttle is also one
Important influence factor.Wefting insertion shuttle includes taking yarn device, driving lever, arc-shaped rack, limit bottom plate.Yarn device is taken to be arranged in arc-shaped rack
On, arc-shaped rack is arranged with limit bottom plate, and limit bottom plate is limited wefting insertion shuttle by contacting with shuttle position-limited wheel and idler wheel
In fixed tracks.It takes yarn device to include tube, tube fixing seat, tension regulator, dial line retaining ring, tube is arranged in yarn
In cylinder fixing seat, the front end of tube fixing seat is arranged in tension regulator, according to the big minor adjustment tension adjustment of required weft tension
Device Tensity size is dialled line retaining ring and is arranged in tube fixing seat, to avoid too small openings, opening support is big.
Wefting insertion shuttle and transmission device carry out cooperative movement by way of rack-and-pinion, and complete n by stepper motor
Wefting insertion shuttle is limited in fixed tracks by a gear synchronous rotation, shuttle position-limited wheel and transmission device, one circle of movement
Complete wefting insertion action.The design is provided with n group transmission device to control the movement of wefting insertion, and complete by way of rack-and-pinion
At entire wefting insertion action, structure is simple, and is able to achieve automation, improves the wefting insertion efficiency of multi-layer cylinder loom.
The picking motion of the multi-layer cylinder loom of the design is by the cooperation of each section, so that wefting insertion action is smooth；Pass through
Accurate control to stepper motor, motor reach synchronous, are not in tooth butt phenomenon；Cooperate other mechanisms of whole equipment, energy
Enough high efficiency complete wefting insertion action, and provide enough weft tension so that appearance of fabrics is fine, it is compound after material
Good mechanical property can be reached.The design structure is simple, and control is accurate, can not can pass through change with yarn intervention
Stepper motor parameter, to realize different filling insertion rates.
