Abstract

The utility model discloses a rapier weaving machine hank limit ware, including first leno heald, second leno heald, hank limit needle, the upper end and the lower extreme of first leno heald and second leno heald set up harness eye and time harness eye respectively, and the inboard of first leno heald and second leno heald all is provided with the spread groove, hank limit needle passes through the spread groove and connects first leno heald and second leno heald, and the outside that first hank limit needle and second twisted the limit needle all is provided with the chip groove, the lower extreme of chip groove is the state of opening. The utility model has the advantages of reasonable design, the type of falling U is set to chip groove through with the leno heald outside, excretes the groove lower extreme promptly and is the state of opening, can ensure to twist the limit needle and can not block up the chip groove at impurity such as the produced short flannel of up -and -down motion in -process, filoplume, dust to the distance of ensureing the removal of leno heald relative up -down is invariable, guarantees that yarn opening angle is unanimous all the time, avoids arrow shaft to break the emergence of yarn phenomenon, and reduce the fault is rateed, improvement work efficiency, increase of service life.

Description

A kind of Rapier looms leno edge machine

Technical field

The utility model belongs to technical field of textile machine, is specifically related to a kind of Rapier looms leno edge machine.

Background technology

The central authorities of the leno heald of the correspondence strand pin both sides, limit that existing leno edge machine adopts do not open, namely the two ends of the groove of leno heald arranged outside are closed, not opening state, when normally working, the leno heald of strand pin both sides, limit relatively alternately moves up and down, it drives strand limit pin to move up and down, in motion process, easily make groove inner accumulated short flannel, filoplume, the impurity such as dust, thus raise strand limit pin, the work of strand limit is caused normally to carry out, because after groove is blocked, the distance of the upper and lower relative movement of strand limit pin shortens, thus cause yarn opening angle to diminish, easily there is the phenomenon that yarn thrusts by the sword head of arrow shaft, finally cause shutting down, affect operating efficiency.

Utility model content

For problems of the prior art, the purpose of this utility model is that design provides a kind of Rapier looms leno edge machine.

Described a kind of Rapier looms leno edge machine, comprise the first leno heald, the second leno heald, strand limit pin, the top and bottom of the first leno heald and the second leno heald arrange harness eye and lower harness eye respectively, the inner side of the first leno heald and the second leno heald is provided with link slot, described strand limit pin connects the first leno heald and the second leno heald by link slot, it is characterized in that the outside of described first leno heald and the second leno heald is provided with chip area, the lower end of described chip area is opening state.

Described a kind of Rapier looms leno edge machine, is characterized in that described first leno heald is identical with the width at the second upper and lower two ends of leno heald.

Described a kind of Rapier looms leno edge machine, it is characterized in that described strand limit pin comprises threading end, contact pin with through wires hole, described contact pin is symmetricly set on the both sides of threading end, and contact pin grafting is arranged in link slot.

Described a kind of Rapier looms leno edge machine, is characterized in that the lower end integral type of described contact pin is provided with prerotation vane.

Described a kind of Rapier looms leno edge machine, it is characterized in that described chip area is arranged along the medium position outside the first leno heald and the second leno heald, and chip area is inverted U.

The utility model reasonable in design, by the chip area outside leno heald is arranged to inverted U, namely discharge launder lower end is opening state, can guarantee that the impurity such as short flannel, filoplume, dust that strand limit pin produces in the process of moving up and down can not block chip area, thus guarantee the constant distance of the upper and lower relative movement of leno heald, ensure that yarn opening angle is consistent all the time, arrow shaft is avoided to thrust the generation of yarn phenomenon, reduce fault rate, increase work efficiency, increase the service life.

In figure: 1-first leno heald, 2-second leno heald, 3-twists limit pin, the upper harness eye of 4-, harness eye under 5-, 6-link slot, 7-chip area, 8-through wires hole, 9-threading end, 10-contact pin, 11-prerotation vane.

Detailed description of the invention

The utility model is further illustrated below in conjunction with Figure of description.

As shown in Figure 1-2, a kind of Rapier looms leno edge machine of the utility model, comprise the first leno heald 1, second leno heald 2, strand limit pin 3, first leno heald 1 is identical with the width at the second leno heald about 2 two ends, the top and bottom of the first leno heald 1 and the second leno heald 2 arrange harness eye 4 and lower harness eye 5 respectively, the inner side of the first leno heald 1 and the second leno heald 2 is provided with link slot 6, strand limit pin 3 connects the first leno heald 1 and the second leno heald 2 by link slot 6, the concrete structure of strand limit pin 3 is, strand limit pin 3 comprises the threading end 9 with through wires hole 8, contact pin 10, contact pin 10 is symmetricly set on the both sides of threading end 9, contact pin 10 grafting is arranged in link slot 6, for making the motion of contact pin 10 in link slot 6 more smooth and easy, the lower end integral type of contact pin 10 is provided with prerotation vane 11, for the impurity such as short flannel, filoplume, dust preventing contact pin 10 from producing in the process of moving up and down drops in leno heald groove, chip area 7 is provided with in the outside of the first leno heald 1 and the second leno heald 2, the lower end of this chip area 7 is opening state, and in inverted U, arrange along the medium position outside the first leno heald 1 and the second leno heald 2.

The utility model leno edge machine is for Rapier looms, during use, be connected with lower harness eye 5 by upper harness eye 4 with selvage device of weaving machine support, twisted warp is through through wires hole 8, along with the operation of loom, first leno heald 1 and the second leno heald about 2 relative movement, twisted warp is constantly advanced, and interweaves with weft yarn simultaneously, namely while twisted warp and body warp carry out harness motion, twisted warp also must be done displacement alternately and move in the both sides of body warp, thus it is flat that selvedge is twisted, and pins natural selvedge.

Strand limit operation principle: one group or several groups of twisted warps are twisted at selvedge place mutually with body warp, interweave simultaneously, form strand limit with weft yarn.Because twisted warp and body warp are interweaved, increase the angle of contact of selvedge between weft yarn, between twisted warp and body warp and extruding angle, greatly strengthen the mutual control ability of filling yarn on intertwined point, thus formed firm, reliably twist limit.
