Description
Technical field
The present invention relates to weaving technology fields, and in particular to a kind of the bringer device and Weft inserting device of rapier loom.
Background technique
Low grammes per square metre carbon fibre fabric refers to the flat filament formed after expanding fibre using carbon fibre tow as warp thread and latitude
Yarn is weaved the height of the fiber volume fraction obtained from, a kind of light-weight fabric.This fabric can be used as reinforcing material,
It is widely used in the fields such as aerospace, automobile manufacture, rail traffic, ship yacht, high-end Leisure Sport articles.Carbon fiber surface
Face is smooth, and friction factor is low, bad clamping, especially with the carbon fiber flat filament of one fixed width.For the fibre for weaving better quality
Fabric is tieed up, during weft yarn clamping, the width after needing to keep flat filament expansion fine does not change, and fiber filament does not interlock, is not bent；No
Silk, not fracture of wire are lost, clamping is reliable.And collet shape should be small as far as possible, to correspondingly reduce shed open size, so avoid through
Yarn is damaged and improves production efficiency.
Currently, domestic only have the automatic low grammes per square metre carbon fiber weaving of Shijiazhuang Changshan Textile Co., Ltd's independent research
Equipment.Wherein flat filament shape weft yarn clamping technique is exactly one of the critical issue for needing to solve.Application No. is
The application of CN201720337129.0 discloses a kind of carbon fiber braider Weft inserting device, and specifically discloses: Weft inserting device peace

Based on above structure, the working principle of the Weft inserting device in the present embodiment are as follows: bringer device is sent in actual use
Filling slippage bar 13 is installed in the bringer slideway of giver 12, and when without outer power drive, bringer collet 11 is in closed state, neither
Clamping is not also opened.In passing latitude process, when bringer device 1 is in process initial position, bringer slide bar 13 by pulling force backward,
Bringer collet 11 is in open configuration, and weft yarn 3 is sent into, and when latitude is passed in advance, bringer slide bar 13 is under the action of bringer sword belt, first phase
For giver 12 march forward direction sliding, driving fourth link 144 drive third connecting rod 143 rotate, and then drive bringer
Maxilla 111 rotates, and bringer collet 11 is closed, and advances and sends out weft yarn 3；When backhaul, when bringer device 1 is in backhaul initial position,
For bringer slide bar 13 by forward thrust, bringer collet 11 is in clamped condition, and when starting to retreat, bringer slide bar 13 is relative to bringer
Arrow shaft 12 is drawn back sliding, and bringer collet 11 is opened, and weft yarn 3 is sent out；
It connects Weft handling device 2 and connects filling slippage bar 23 in actual use and be installed on and connect the connecing in filling slippage road of latitude arrow shaft 22, no external force is driven
When dynamic, connect latitude collet 21 and be in closed state, neither clamp nor open；When wefting insertion process, connects Weft handling device 2 and be in process starting
When position, connect filling slippage bar 23 by pulling force backward, it is in clamped condition to connect latitude collet 21, when travelling forward, connect filling slippage bar 23 to
Direction of advance sliding, the 8th connecting rod 244 of driving drive seven-link assembly 243 to rotate, and then drive and connect the rotation of latitude maxilla 211, open
It connects latitude maxilla 211, when reaching insertion position, connects latitude collet 21 and be in open configuration, convenient for feeding weft yarn 3, when backhaul, connect latitude and fill
It when setting 2 in backhaul initial position, connects latitude collet 21 and is opened by thrust, when starting to retreat, connect filling slippage bar 23 and move in the reverse direction
Dynamic, clamping connects latitude maxilla 211, introduces weft yarn 3.When connecing latitude collet 21 and moving to the one end for connecing the entrance necking of latitude arrow shaft 22, draw
Latitude terminates, and connects the driving of filling slippage bar 23 and connects the opening of latitude collet 21, connects latitude collet 21 and discharge weft yarn.
In two embodiments disclosed above, the bringer device 1 in embodiment one can also connect latitude in embodiment two
Device 2 is used cooperatively, in embodiment one connect Weft handling device 2 can also and embodiment two in bringer device 1 be used cooperatively, as long as
It is able to achieve the effect of wefting insertion.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be in the premise for not departing from spirit of the invention
Under make a variety of changes.
