Description
Technical field
The present invention relates to a kind of edge slitter device for weaving yarns without slitter edges of shuttleless loom, belong to technical field of textile machine.
Background technology
Different with fly-shuttle loom, because shuttleless loom generally is unilateral weft supply, so every of shuttleless loom weft yarn is all cut off after forming fabric in weaving process, so that the carrying out continuously of wefting insertion process.In order to guarantee that every weft yarn is inweaving the preceding maintenance certain force of strain of fell (promptly forming fabric), the length of every weft yarn is more longer than the fabric width of fabric, so that as the retained part of weft inserting apparatus.After forming fabric, this part unnecessary weft yarn will be cut, and to guarantee fabric the burr neat, that length is short is arranged.At present, nearly all shuttleless loom all adopts the slitter edge yarn to twist the weft yarn head end, to guarantee that unnecessary weft yarn is cut smoothly, guarantees that simultaneously the weft yarn at the selvedge place of fabric has certain force of strain, helps fabric and forms firm, smooth, a stiffening selvedge.
The redundance of weft yarn generally is after being lived, deflected from fell by the slitter edge skein, to be cut off by scissors in the traditional design.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple in structure, the electric power and the supplies consumption that can reduce textile mills are provided, reach energy-saving and cost-reducing effect, improve the edge slitter device for weaving yarns without slitter edges of weft yarn utilization rate.
According to technical scheme provided by the invention, described edge slitter device for weaving yarns without slitter edges, comprise refuse yarn scissors seat, suction pipe seat and suction pipe air inlet seat, on refuse yarn scissors seat, be fixed with fixed blade, on refuse yarn scissors seat, be hinged with cutting blade by bearing pin, described cutting blade cooperates with fixed blade, fixed installation refuse yarn suction pipe on the suction pipe air inlet seat, this refuse yarn pipette support is located on the suction pipe seat, on the suction pipe air inlet seat, also be provided with air inlet pipe and refuse yarn efferent duct, described air inlet pipe, refuse yarn efferent duct and refuse yarn suction pipe three keep normal open, the auxilliary spirt tracheae of fixed installation on refuse yarn scissors seat, be installed with auxilliary nozzle on refuse yarn scissors seat, the suction pipe suction casing mouth of pipe of refuse yarn suction pipe is aimed in the outlet of described auxilliary nozzle.
Described refuse yarn suction pipe is made of suction pipe suction casing and suction pipe construction section, and the output of suction pipe construction section is fixed on the suction pipe air inlet seat, and the input of suction pipe suction casing caliber on its output direction dwindles gradually, makes suction pipe suction casing flare.
On cutting blade, offer the connecting rod bayonet socket.
In the loom operation process, compressed air enters the refuse yarn suction pipe from air inlet pipe, and compressed air sprays from the refuse yarn efferent duct, so form negative pressure at the suction inlet place of refuse yarn suction pipe; After the wefting insertion process finished, weft yarn was firmly held by the refuse yarn suction pipe, and swings forward with slay under the acting in conjunction of auxilliary nozzle and refuse yarn suction pipe, inweaves fell, forms fabric; The weft yarn that forms fabric is along with fabric moves forward, and the head of weft yarn is still held by the refuse yarn suction pipe, and swings backward with slay; When weft yarn entered the cutting edge part of cutting blade and fixed blade, under the drive of scissor linkages, cutting blade rotated, and sound blade closure is cut off weft yarn.The weft yarn of cutting off has promptly become refuse yarn, and refuse yarn is transported in the refuse yarn bucket along refuse yarn suction pipe, refuse yarn efferent duct under the effect of refuse yarn suction pipe suction; After refuse yarn cut short, scissor linkages drove cutting blade and resets.
Advantage of the present invention is as follows:
1, owing to no longer adopt the slitter edge skein to live the weft yarn head end,, simplified the structure of loom greatly, simultaneously, reduced the operating cost of loom so saved a series of devices relevant with the slitter edge yarn;
2, owing to no longer need independent opening heald frame to finish the harness motion of slitter edge yarn,, reached energy-saving and cost-reducing effect so reduced the electric power and the supplies consumption of textile mills;
3, after weft yarn is introduced shed open, directly hold the weft yarn head end, can suitably shorten the length of redundance weft yarn like this, improve the utilization rate of weft yarn by suction pipe.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a stereogram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: described edge slitter device for weaving yarns without slitter edges, comprise the refuse yarn scissors seat 1 that relative position is fixing, suction pipe seat 2 and suction pipe air inlet seat 3, on refuse yarn scissors seat 1, be fixed with fixed blade 4, on refuse yarn scissors seat 1, be hinged with cutting blade 6 by bearing pin 5, described cutting blade 6 cooperates with fixed blade 4, fixed installation refuse yarn suction pipe 7 on suction pipe air inlet seat 3, this refuse yarn suction pipe 7 is erected on the suction pipe seat 2, on suction pipe air inlet seat 3, also be provided with air inlet pipe 8 and refuse yarn efferent duct 9, described air inlet pipe 8, refuse yarn efferent duct 9 keeps normal open with refuse yarn suction pipe 7 threes, the auxilliary spirt tracheae 10 of fixed installation on refuse yarn scissors seat 1, be installed with auxilliary nozzle 11 on refuse yarn scissors seat 1, the suction pipe suction casing 7a mouth of pipe of refuse yarn suction pipe 7 is aimed in the outlet of described auxilliary nozzle 11.
Described refuse yarn suction pipe 7 is made of suction pipe suction casing 7a and suction pipe construction section 7b, the output of suction pipe construction section 7b is fixed on the suction pipe air inlet seat 3, the input of suction pipe suction casing 7a caliber on its output direction dwindles gradually, makes suction pipe suction casing 7a flare.
On cutting blade 6, offer connecting rod bayonet socket 12.
Refuse yarn scissors seat 1, suction pipe seat 2 and suction pipe air inlet seat 3 are fixed on the slay by square head screw respectively, and its position can change along with the variation of fabric width.Fixed blade 4, cutting blade 6, auxilliary spirt tracheae 10 and auxilliary nozzle 11 are installed on the refuse yarn scissors seat 1.Auxilliary nozzle 11 is aimed at the suction pipe mouth of refuse yarn suction pipe 7, and refuse yarn suction pipe 7 is fixed on the slay by suction pipe air inlet seat 3.Suction pipe air inlet seat 3 two ends are equipped with compressed air inlet pipe 8 and refuse yarn efferent duct 9 respectively.
The concrete course of work of the present invention is as follows:
In the loom operation process, compressed air enters the refuse yarn suction pipe 7 from air inlet pipe 8, and compressed air sprays from refuse yarn efferent duct 9, so form negative pressure at the suction inlet place of refuse yarn suction pipe 7.After the wefting insertion process finished, weft yarn was firmly held by refuse yarn suction pipe 7, and swings forward with slay under the acting in conjunction of auxilliary nozzle 11 and refuse yarn suction pipe 7, inweaves fell, forms fabric.The weft yarn that forms fabric is along with fabric moves forward, and the head of weft yarn is still held by refuse yarn suction pipe 7, and swings backward with slay.When weft yarn entered the cutting edge part of cutting blade 6 and fixed blade 4, under the drive of scissor linkages, cutting blade 6 rotated, and sound blade closure is cut off weft yarn.The weft yarn of cutting off has promptly become refuse yarn, and refuse yarn is transported in the refuse yarn bucket along refuse yarn suction pipe 7, refuse yarn efferent duct 9 under the effect of refuse yarn suction pipe 7 suction.After refuse yarn cut short, scissor linkages drove cutting blade 6 and resets.
