Description

The Rapier looms latitude is cut device

Technical field

The utility model relates to a kind of weaving apparatus.

Background technology

Existing little Rapier looms latitude is cut device and is all adopted the active type latitude to cut device.It is to drive the inboard sprocket rotation of A word pin wallboard by the sprocket wheel that is fixed on the d-axis by chain drive that latitude is cut device, sprocket wheel by the wallboard outside rotates scissors shaft by the sprocket wheel that chain drive is fixed on the scissors shaft again, scissors shaft is again by stepping up dish, the trough of belt dish, eccentric square drives the Scissors box axle and rotates, the weft cutter cam that is fixed on the Scissors box axle drives thereupon, the lower scissors bar moves up and down respectively, being fixed on up and down, the last bottom knife of knife bar front end moves up and down respectively thereupon, open as scissors, closure is cut off weft yarn when closure.Loom fortune circles closure once, finishes and once cuts the latitude process.

This cover active type latitude is cut device and is had following problem:

One, waste raw material:

Slitter edge warp thread 6-12 root must be reserved in the fabric left side in weaving process, about every weft yarn 30MM, is cut as waste disposal after finishing, and causes wastage of material.

Two, fault rate height:

1. because this covering device power transmission route is long, adopt chain drive; Through-drive; Cam, the lever transmission.Chain has loosening slightly; The sprocket wheel jackscrew, the key bar has loosening slightly; Each parts has wearing and tearing slightly, all can be that running is unstable, causes that to cut the latitude time not accurate, and it is bad to cut latitude.

2. because last bottom knife is a move toward one another, can not be gapped during interlock, so be easy to wearing and tearing, cause blade not sharp, cause that to cut latitude bad.

Three, maintenance trouble, loaded down with trivial details: because active type latitude shear structure complexity, parts are many, and each parts goes wrong and can cause all that to cut latitude bad, and latitude occurring cutting, to be difficult to judgement when bad be which parts goes wrong actually.

Because each parts is all done 360 degree with loom and rotated, it is good to keep latitude to cut latitude, will often adjust the chain degree of tightness, the fit clearance of each parts and time

Four, dangerous: because scissors shaft steps up dish, the trough of belt dish can't install protective cover additional and be exposed at outward on workman's work top, does 360 degree motions with loom, and the workman runs into when normal running especially easily, careless slightly will being bruised, and strand is hindered.

Five, can only be applicable to a weft accumulator, single parallel is sheared, and limitation is big.

Summary of the invention

Problems such as the purpose of this utility model provides a kind of Rapier looms latitude and cuts device, wastes raw material to solve prior art, fault rate height, maintenance trouble, dangerous, and can only be applicable to a weft accumulator, and single parallel is sheared, and limitation is big.

The utility model mainly is made up of transmission mechanism, cutting out section, and solving the technical scheme that its problem adopts is to adopt the underneath type blade to cooperate hollow hook to constitute cutting out section, and the blade of cutting out section is arranged between strap and the ambulatory splint, bolt tightening; Strap and sliding blade frame base plate are made one, constitute inverse-T-shaped structure movable blade horse, on the sliding blade frame base plate transverse bottom plate regulating tank are set, and cooperate with the longitudinal tool rest rail groove of adjustable setting, and bolt flexibly connects; The adjustable setting cross section is " ┓ " shape structure, and top is provided with the knife rest rail groove, and the side is provided with the base regulating tank.The hollow hook of cutting out section is arranged between Scissors box and the temple device seat, and hollow hook cross section is for falling " U " shape structure, and its front end downside is circular-arc, and bottom also is designed to arc, and two arc junctions are provided with and collude the latitude point, and colluding latitude point is the right angle bulge-structure; Hollow hook rear panel is provided with semiclosed storage latitude chamber colluding latitude point rear side, and anter is provided with open semicircle storage latitude storehouse; " U " shape groove of opening is set in the middle of the hollow hook rear portion, between " U " shape groove hollow interlayer circular gasket is set; Hollow hook is connected with recessed formula plain cushion by " U " shape groove at rear portion, and recessed formula plain cushion is fixed between Scissors box and the temple device seat.

It is simple in structure adopting good effect of the present utility model, with low cost, easy care, because this device adjustable setting is directly installed on the slay and with slay and swings, power directly passes to blade by slay, there is not intermediate transfer, the position of blade, very firm, it is very accurate to cut the yarn time, can finish the alternately cutting of multistrand yarn, reduce greatly because of cutting the bad staplings parking that causes of latitude, the slitter edge and the irregular cracked ends that causes of slitter edge warp thread degree of tightness that can reduce in the woven process stop, thereby reduce labor strength, save man-hour, improve operating efficiency, increased safety coefficient.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the utility model front view;

Fig. 2 is the utility model right view;
