The utility model relates to a shuttle box for shuttle looms. The utility model is an improvement of present shuttle boxes for shuttle looms. The shuttle box can be used to effectively reduce breaking rate, improve production efficiency. The shuttle box is featured with simple structure, easy retrofit and low production cost. The utility model discloses an anti-breaking shuttle box, which is installed on both sides of the sley and swings together with the sley. Top plate and bottom plate of the shuttle box are fixed on the sley, and front plate of the shuttle box is fixed on the bottom plate. The shuttle-hitting panel is movable fixed on the back of the shuttle box, and the back of the shuttle-hitting panel is pressed with a shuttle-hitting pressure spring on the top. A soft sheet in installed on inner side of the front plate, an arch hole is machined on the soft sheet, and a metal wire is threaded through the hole and through the front plate hole successively and is used to fix the soft sheet on the front plate. The soft sheet is made of cowskin.

Description

Anti-breaking winding shuttle box

Technical field

The utility model relates to a kind of parts of textile machine, specifically is the shuttle box of fly-shuttle loom.

Background technology

Fly-shuttle loom in the textile machine is formed by shedding mechanism, picking mechanism, beating-up mechanism, the warp let-off and spooler and shuttle changing mechanism.Wherein the slay that reed is housed in the beating-up mechanism is made reciprocally swinging under the drive of motor and crank, and shuttle is just made reciprocal motion of weft-insertion on slay wood.Therefore, when slay is flapped toward heading, reed just will be included the tram of shed open in and squeeze into fell, so finish beating-up.

Disconnected winding, just the tram that the shuttle from motion is drawn when weaving breaks suddenly, is the most common failure of weaving at present when producing.One generation is broken winding, and operating personnel just must shut down and remove fracture of wire head cleaning fell, start again then, and one stops out and need spend many times.Disconnected winding rate height, productivity ratio just descends greatly.Because the motion of loom is a compound movement, disconnected winding problem relates to multiple factor again, so head it off has certain difficulty.Up to the present, still do not obtain the solution of essence.

The utility model content

The purpose of this utility model provides a kind of improvement of fly-shuttle loom shuttle box, and this shuttle box should be able to overcome the deficiency of above-mentioned background technology, can effectively reduce disconnected winding rate, enhance productivity, and have simple in structure, repacking easily, the characteristics of low production cost.

The technical scheme that the utility model proposes is:

Anti-breaking winding shuttle box, this shuttle box are installed in the slay both sides respectively and swing with slay; Top board in the shuttle box, base plate are fixed on the slay, and front apron then is fixed on the base plate, and box swell movably is positioned at the shuttle box rear portion again, and the back of box swell also roof pressure the shuttle braking stage clip, and soft thin slice is equipped with in the inboard of described front apron.

Be shaped on arcuate socket on the described soft thin slice, the hole of being passed successively on this hole and the front apron by wire is fixed on soft thin slice on the front apron in addition.

Described soft thin slice is an ox-hide.

The utility model is when weaving; each shuttle is clamped between shuttle and the soft thin slice by the parallel of drawing in the shuttle fairlead when slay wood is squeezed into shuttle box seat, front and rear baffle clamping shuttle, has protected no longer damaged of parallel; thereby disconnected winding rate reduces significantly, and production efficiency obviously improves.According to measuring and calculating, same loom is in the same time, and the quilt cover of production is brought up to 20, output raising 11% from 18; Because fault reduces, the board that the machine personnel of repairing can keep an eye on has enlarged 30%; Economic benefit is fairly obvious.In addition, because the structure of changing is very simple, repacking is very easy to, the cost of spending few, be particularly suitable for box-loom.

The specific embodiment

According to further investigation, the inventor finds that disconnected winding main cause is shuttle when entering shuttle box, and preceding, baffle plate and box swell are lived shuttle by the strength cramping of shuttle braking stage clip and forced its deceleration (prevent again shuttle from beating) and stop at assigned address.This moment the parallel of from the shuttle fairlead, drawing by cramping between shuttle front and front apron; Because front apron is a metal, shuttle generally is again that hardwood is made, and parallel is very easily impaired by the two cramping, so that it is disconnected winding that fracture one takes place when throwing a spear next time.Because the shuttle fairlead is arranged in shuttle one side (figure is the right side), thereby a disconnected winding side that often occurs in slay.

The inventor has taked to install additional in the front apron inboard way of soft thin slice (recommending to use ox-hide, also available rubber or plastics) according to this discovery.So, the parallel of drawing from the shuttle fairlead between the ox-hide of shuttle front and front apron, is subjected to the cramping of one hard one soft two kinds of objects by cramping, and parallel is unlikely impaired with regard to being subjected to better protect, and then disconnected winding phenomenon also just descends significantly.

Specifically as shown in Figure 1 and Figure 2, this anti-breaking winding shuttle box, this shuttle box 2 are installed in the left side of slay 1 and right side (only showing the right side among the figure) respectively and swing with slay, and reed 4 then is housed in the slay; Top board 2-3, base plate 2-5 in the shuttle box seat are fixed on the slay; Because what show among the figure is two shuttle boxs, the base plate 2-4 that therefore goes up shuttle box becomes the top board of shuttle box down simultaneously again; Front apron 2-2 then is fixed on the base plate, and the height of front apron generally is 1/3rd to 1/2nd of a shuttle box height; Box swell 2-1 movably is positioned at the shuttle box rear portion again, and box swell is can be around N spot wobble (generally being connected on the slay with hinge) among Fig. 2; The back that other has shuttle braking stage clip 10 roof pressures box swell is so that the effect of common cooperation performance shuttle braking.Above structure is the structure of existing fly-shuttle loom shuttle box.Soft thin slice 3 (front apron in the shuttle box on slay left side and right side is all so installed) is equipped with in the inboard of described front apron, and particular location by Fig. 3 and Fig. 1 (because of invisible at the back, the spy represents with hatching among Fig. 1) as can be known.Also have picker stick 12 and leather block 11 among Fig. 1.

Fig. 4, Fig. 5 represent the state of shuttle 5 in Fig. 1, Fig. 2 respectively.Among the figure as can be known the shuttle fairlead just in time in the face of front apron, thereby from cop 7 unwindings and by the parallel 6 of drawing the shuttle fairlead just between the front of shuttle and front apron by cramping.And in slay opposite side (left side), the parallel that shuttle is drawn in the shuttle box then can be by cramping (because the parallel of drawing be in forward front of shuttle in the parallel hole),

Described soft thin slice is advisable with ox-hide, and the soft or hard appropriateness is firm again.Fixed form can have multiple, and available securing member is fixed, or bonding with the high strength bonding agent.The mode that the utility model is recommended is to make an arcuate socket 3-1 as shown in Figure 6 on ox-hide, and the hole of being passed successively on this hole and the front apron by wire is fixed on soft thin slice on the front apron in addition, has guaranteed that the contact-making surface of ox-hide and shuttle does not all have hard thing.And the making of arcuate socket is also very simple, only need bore straight hole then as shown in Figure 7 more as shown in Figure 8 earlier with the ox-hide bending, then stretching ox-hide arcuate socket.

Still it should be noted that: clear for drawing, each figure is not all according to true ratio.
