Abstract
The utility model discloses a pressure-adjustable nozzle of an air jet loom. The pressure-adjustable nozzle comprises a nozzle pipe body, wherein a weft yarn inlet is formed in one side of the nozzle pipe body and is communicated with a weft yarn guide pipe arranged inside the nozzle pipe body; a jet pipe isolated from the weft yarn guide pipe is arranged on the other side of the nozzle pipe body; an air inlet channel is formed in the nozzle pipe body; a valve plate and a stopping sheet which are in contact with each other and are both provided with a plurality of air holes are arranged between the inner wall of the nozzle pipe body and the jet pipe; a bulge capable of sliding along a sliding chute formed in the surface of the pipe body is arranged on the stopping sheet in the radial direction; and the ventilating area of the holes in the valve plate is adjusted by sliding the bulge in the sliding chute, so that a part of air is exhausted from the air holes in the valve plate, and the air pressure can be adjusted.
Description
Technical field
The utility model relates to a kind of nozzle, especially the nozzle in air-jet loom
Background technology
Air-jet loom is to adopt the jet-stream wind weft traction to pass through the shuttleless loom of shed open.Operation principle is to utilize air as the wefting insertion medium, with the compressed air stream that ejects, weft yarn is produced frictional traction and draws, and the weft yarn band is crossed shed open, reaches the purpose of wefting insertion by the jet of jet generation.This filling insertion way can make loom realize the high speed high yield.But the excessive generation that also can cause the phenomenons such as weft yarn broken yarn of the air pressure in nozzle affects crudy.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of nozzle that can adjustable pressure.
For addressing the above problem, the utility model provides a kind of air-jet loom pressure-adjustable nozzle, comprise nozzle body, nozzle body one side is provided with the weft yarn entrance, the weft yarn entrance communicates with the weft yarn skirt that is arranged on nozzle body inside, the opposite side of nozzle body is provided with the playpipe of being separated by with the weft yarn skirt, also be provided with on nozzle body into the gas passage, be provided with the valve block and the catch that are in contact with one another and all have some pores between nozzle body inwall and playpipe, catch radially is provided with the projection that can slide along the chute of being located at the nozzle body surface.
As further improvement of the utility model, be arranged at valve block identical with the position with pore opening in catch.
As further improvement of the utility model, enter also to be provided with screen pack in the gas passage.
Beneficial effect:
(1) regulate the breathing area in hole on valve block by the projection in the slip chute, and then make a part of gas discharge by the pore on valve block, adjustable pressure;
(2) enter also to be provided with screen pack in the gas passage, prevent that airborne impurity from entering playpipe, stop up playpipe, yarn quality is penetrated in impact.

Comprising: weft yarn entrance 1, weft yarn skirt 2, enter gas passage 3, screen pack 4, valve block 5, projection 6, catch 7, pore 8, the second air cavity 9, the 3rd air cavity 10, playpipe 11, nozzle body 12, the first air cavity 13, chute 14.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises nozzle body 12, nozzle body 12 1 sides are provided with weft yarn entrance 1, weft yarn entrance 1 communicates with the weft yarn skirt 2 that is arranged on nozzle body 12 inside, the opposite side of nozzle body 12 is provided with the playpipe 11 of being separated by with weft yarn skirt 2, also be provided with on nozzle body 12 into gas passage 3,11 of nozzle body 12 inwalls and playpipes are provided with valve block 5 and the catch 7 that is in contact with one another and all has some pores 8, and catch 7 radially is provided with the projection 6 that can slide along the chute 14 of being located at nozzle body 12 surfaces.
As extremely shown in Figure 4 in Fig. 2, in the utility model, pore 8 sizes that can arrange in valve block 5 and catch 7 are identical with the position, when projection 6 is pressed chute 14 tracks slip in chute 14, pore 8 places on valve block 5 and catch 7 are also in different positions, for example overlap fully, partially overlap and block fully, by regulating the breathing area adjustable pressure of pore 8.
It is the partial structurtes schematic diagram of the first embodiment of the present utility model as Fig. 5, projection 6 in slip chute 14, make the pore 8 in valve plate and catch 7 be blocked fully, gas after filtering through filter screen 4 enters into the first air cavity 13 of nozzle body 12 by entering gas passage 3, because pore 8 is blocked fully, gas can only enter in the second interior air cavity 9 of playpipe 11, and this moment, air pressure was maximum.
it is the partial structurtes schematic diagram of the second embodiment of the present utility model as Fig. 6, projection 6 in slip chute 14, make valve plate overlap fully with pore 8 in catch 7, gas after filtering through filter screen 4 enters into the first air cavity 13 of nozzle body 12 by entering gas passage 3, because pore 8 is opened fully, gas can not only enter in the second interior air cavity 9 of playpipe 11, and in the 3rd air cavity 10 that can enter by the pore 8 on valve block 5 and baffle plate, when the total amount of gas is constant, increase breathing area, can reduce air pressure, at this moment, breathing area is maximum, air pressure is also minimum.
it is the partial structurtes schematic diagram of the 3rd embodiment of the present utility model as Fig. 7, projection 6 in slip chute 14, make the pore 8 in valve plate and catch 7 partially overlap, gas after filtering through filter screen 4 enters into the first air cavity 13 of nozzle body 12 by entering gas passage 3, because pore 8 is opened fully, most of gas can not only enter in the second interior air cavity 9 of playpipe 11, and in the 3rd air cavity 10 that small part gas can enter by the pore 8 on valve block 5 and baffle plate in addition, when the total amount of gas is constant, increase breathing area, can reduce air pressure, this moment, air pressure was between minimum and maximum, and the area that can overlap by regulating pore 8, thereby control the value of air pressure.
The above describes in detail embodiment of the present utility model by reference to the accompanying drawings, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
