Abstract
The utility model discloses a suction nozzle of suction gun, including the suction nozzle body, the suction nozzle body is hollow copper tubular construction, and the silk mouth that advances of suction nozzle body is equipped with porcelain mouth, and porcelain mouth fixes on silk mouth circumference inner wall that advances. The suction nozzle of the thread suction gun reduces damage caused by the fact that the suction nozzle of the thread suction gun accidentally touches the surface of a hot roller and reduces the self abrasion speed of the suction nozzle in the thread suction gun threading process.
Description
The technical field is as follows:
the utility model relates to a polyester yarn production field specifically says a suction nozzle of suction gun.
Background art:
in the production process of the polyester filament FDY, a yarn suction gun is often used in a winding working section. The suction gun is mainly used for sucking the tows after the tows are broken, guiding the tows to smoothly pass through a set yarn path and finally hanging the yarns on a paper tube of a winding device. Suction nozzles of general wire suction guns purchased in the market are all made of stainless steel, and in the using process, because two groups of hot rollers and wire separating rollers which run at high speed are arranged on a wire path, the suction nozzles of the wire suction guns often touch the hot rollers to cause surface damage, and further the hot rollers cannot be used. In addition, the spinning speed is about 4500 m/min, and the stainless steel suction nozzle is abraded too fast and is frequently replaced due to the fact that tows pass through the suction nozzle at a high speed, so that the use cost is increased.
The utility model has the following contents:
the utility model aims to solve the technical problem that a provide one kind and use the thread suction rifle to end the in-process, reduce because of the suction nozzle of thread suction rifle touch the hot-rolling surface carelessly and cause the damage and reduce the thread suction rifle suction nozzle of suction nozzle self wearing and tearing speed.
The technical solution of the utility model is that, a suction nozzle of suction gun is provided, including the suction nozzle body, the suction nozzle body is hollow copper tubular construction, and the silk mouth that advances of suction nozzle body is equipped with porcelain mouth, and porcelain mouth fixes on silk mouth circumference inner wall.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: through the structural improvement, the service life is prolonged, the processing is convenient, and the using effect is good.
Preferably, the ceramic nozzle is of a hollow cylindrical structure, and the end face of the ceramic nozzle wire inlet end is a convex curved surface. The friction is reduced.
Furthermore, the inner end of the screw inlet of the suction nozzle body is provided with a step surface, the outer end of the ceramic nozzle is provided with a flanging, and the flanging is placed on the step surface. Not only is convenient to fix, but also can reduce the abrasion of strand silk.
Furthermore, the inner diameter of the wire inlet end of the suction nozzle body is smaller than that of the other end of the suction nozzle body.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in figure 1, the suction nozzle of the thread suction gun comprises a suction nozzle body 1, wherein the suction nozzle body 1 is of a hollow copper pipe structure, a thread inlet 11 of the suction nozzle body 1 is provided with a porcelain nozzle 2, and the porcelain nozzle 2 is fixed on the circumferential inner wall of the thread inlet 11. In other words, the stainless steel suction nozzle of the suction gun is detached, a copper rod with the increased appearance diameter and the increased length is manufactured by brass, then a through hole is drilled, the copper suction nozzle with the internal aperture and the internal thread consistent with the original stainless steel suction nozzle is manufactured, the porcelain nozzle 2 with the low friction coefficient used in the chemical fiber field is selected, the porcelain nozzle 2 is of a hollow columnar structure, the end face of the wire inlet end of the porcelain nozzle 2 is a convex curved surface, the inner end of the wire inlet end of the suction nozzle body 1 is provided with a step surface 12, the outer end of the porcelain nozzle 2 is provided with a flanging 21, and the flanging 21 is placed on the step surface 12. And finally, adhering the porcelain nozzle to the inner hole of the copper suction nozzle by using strong glue. In order to facilitate the wire guiding, the inner diameter of the wire feeding end of the suction nozzle body is smaller than that of the other end.
When the filament bundle is sucked by the filament suction gun, the filament bundle is guided to wind on the hot roller rotating at high speed along the filament path, even if the filament bundle accidentally touches the surface of the hot roller, the suction nozzle of the filament suction gun is made of soft brass, so that the surface of the suction nozzle is abraded in the touch process, and the surface of the hot roller is protected. Secondly, because of the lower porcelain mouth of coefficient of friction has been embedded into to copper suction nozzle entry, even the silk bundle passes through at a high speed, porcelain mouth does not scald, does not abrade for copper suction nozzle can use for a long time, has reduced use cost.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
