Abstract

The utility model discloses a weft-cutting device of a rapier loom. The weft-cutting device of the rapier loom comprises a rapier rail frame of the loom, upper scissors and lower scissors, wherein the upper scissors and the lower scissors are arranged at one end of a licker-in of the loom and are located at the upper side and the lower side of weft respectively, a bent support is arranged on the inner side surface of the rapier rail frame, a bent part of the support faces the licker-in, the bent tail end of the support is connected with a bearing, the lower scissors are fixedly connected with a scissor support of the loom, the scissor support is fixedly connected with a side support main support of the loom, the scissor support is movably connected with a rotation rod through a shaft sleeve part, one end of the rotation rod is fixedly connected with a rotation shaft of the upper scissors, the other end of the rotation shaft is fixedly connected with a Y-shaped shifting fork, and the circumferential surface of the bearing is connected with a concave top surface of the Y-shaped shifting fork in a shifting mode. The weft-cutting device of the rapier loom will not generate structural interference, the upper scissors and the lower scissors can get close to an effective weaving area edge to the maximum extent, and waste cloth edges are not generated theoretically. Due to the fact that parts are reduced largely, the weft-cutting device of the rapier loom is simple in structure, reliable in motion, convenient to debug and ideal in use effect.

Description

A kind of Rapier looms cut Weft handling device

Technical field

The utility model belongs to technical field of textile machine, relates to a kind of Weft handling device of cutting of Rapier looms.

Background technology

Rapier looms be by send latitude sword with connect latitude sword by parallel together with warp knitting.In the process of weaving cotton cloth, at Rapier looms two ends, can produce the slitter edge of certain size, in order not allow the parallel at this place retract because of the elasticity of itself, be also provided with in addition through sideline, play the effect that this place's parallel is clamped, avoid the generation of substandard products cloth.General employing is cut Weft handling device the parallel of Rapier looms two ends generation is cut off, but it is perfect not enough at present to cut Weft handling device technology, can not avoid the interference with beating-up steel-buckle completely, therefore can not be too near to effective knitting zone, thereby can not farthest cut useless parallel, cause the waste of useless selvedge very large.

The Weft handling device form of cutting of the Rapier looms of prior art is a lot, its general structure comprise be located at loom frame one side scissors casing, be located at licker-in outer face side and lay respectively at upper scissors and the lower scissors on parallel both sides; The shank of upper scissors and lower scissors is all arranged in scissors casing, by scissors casing with the cam gear of the device such as arrow shaft rail bracket interlock periodically folding to complete, cut latitude function.

Adopt the cutting Weft handling device and certainly can normally use of Rapier looms of such technology, but it is relatively many to exist parts, upper and lower two scissors close up the time point of cutting latitude action and send latitude sword and connect the problems such as the synchronous debugging of latitude sword point actuation time, arrow shaft rail bracket swing point actuation time etc. is relatively complicated, fault rate is high, useless selvedge waste is large, and result of use is desirable not enough.

Utility model content

For overcoming the deficiencies in the prior art, the utility model provide a kind of simple in structure, reliable in action, failure rate is low, debugging convenient, in theory can not produce useless selvedge, result of use more preferably Rapier looms cut Weft handling device.

The utility model is to reach the technical scheme that above-mentioned technical purpose adopts to be: a kind of Rapier looms cut Weft handling device, comprise loom arrow shaft rail bracket, be located at of loom licker-in and lay respectively at upper scissors and the lower scissors on the upper and lower both sides of parallel; On the medial surface of arrow shaft rail bracket, be provided with bending shape support, the bending part of support is towards licker-in direction; On the bending end of support, be connected with bearing; Lower scissors is fixedly connected with the Holder for scissors of loom; Holder for scissors is fixedly connected with the total support of temple of loom; On Holder for scissors, by sleeve member, be connected with bull stick; One end of bull stick is fixedly connected with the rotating shaft of upper scissors, and the other end of bull stick is fixedly connected with Y shape shift fork; The periphery of bearing is stirred and is connected with the concave crown face of Y shape shift fork.

Described arrow shaft rail bracket is in backup short thrust roller direction and return while putting in place, and the concave crown face of the periphery of bearing and Y shape shift fork is by connecting, and meanwhile, upper shearing blade face and lower scissors sword face are cut to close completely with parallel and be connected.

Described lower scissors is barb-shaped lower scissors, and barb upward.

The beneficial effects of the utility model are: because lower scissors maintains static, upper scissors and the interlock of arrow shaft rail bracket, can not produce constructive interference, and therefore upper lower scissors can press close to effectively to knit edge, district to greatest extent, can not produce useless selvedge in theory; Therefore because parts greatly reduce, simple in structure, reliable in action, debugging are convenient; Result of use is better.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail.Wherein:

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is partial simplified schematic diagram of the present utility model.

Marker number in accompanying drawing is described as follows: licker-in 1, upper scissors 2, bull stick 3, bearing 4, support 5, Y shape shift fork 6, arrow shaft rail bracket 7, lower scissors 8

The specific embodiment

Embodiment of the present utility model, as shown in Figure 1 and Figure 2, a kind of Rapier looms cut Weft handling device, comprise loom arrow shaft rail bracket 7, be located at of loom licker-in 1 and lay respectively at upper scissors 2 and the lower scissors 8 on the upper and lower both sides of parallel; On the medial surface of arrow shaft rail bracket 7, be provided with bending shape support 5, the bending part of support 5 is towards licker-in 1 direction; On the bending end of support 5, be connected with bearing 4; Lower scissors 8 is fixedly connected with the Holder for scissors of loom; Holder for scissors is fixedly connected with the total support of temple of loom; On Holder for scissors, by sleeve member, be connected with bull stick 3; One end of bull stick 3 is fixedly connected with the rotating shaft of upper scissors 2, and the other end of bull stick 3 is fixedly connected with Y shape shift fork 6; The periphery of bearing 4 is stirred and is connected with the concave crown face of Y shape shift fork 6.

Described arrow shaft rail bracket 7 is in backup short thrust roller 1 direction and return while putting in place, and the concave crown face of the periphery of bearing 4 and Y shape shift fork 6 is by connecting, and meanwhile, upper scissors 2 sword faces and lower scissors 8 sword faces are cut to close completely with parallel and are connected.

Described lower scissors 8 is barb-shaped lower scissors 8, and barb upward.

The utility model utilizes the swing of arrow shaft rail bracket 7 to drive scissors 2 to complete to cut and closes action and realize and cut latitude.

The utility model is cut Weft handling device and is arranged on and send latitude sword one side, and the licker-in 1 of the relative existing apparatus of length of licker-in 1 and lid and the length of lid should suitably shorten.
