Description

Conical spray hole auxiliary nozzle for air jet loom

Technical Field

The utility model belongs to the technical field of weaving equipment auxiliary device, concretely relates to air jet loom's auxiliary nozzle.

Background

The auxiliary nozzle is also called relay nozzle, and it sprays air flow to the upper oblique direction of the weft yarn advancing direction. The auxiliary nozzle sprays before the weft reaches to drive air in front of the weft to move, so that the resistance of the air to the weft is reduced, and the auxiliary nozzle enables the front end of the weft to generate relative negative pressure to attract the weft. The main function of the auxiliary nozzle is to supplement the energy of the main jet stream, so that the weft insertion stream can keep a certain speed and send the weft yarns through the shed in a relay mode. During normal operation, the total gas consumption and the gas pressure of the auxiliary nozzle are related to the reed width on the machine. The performance and appearance quality of the auxiliary nozzle directly affect the speed of the loom, the weaving efficiency, the energy consumption and the quality of the fabric.

The applicant discloses a Chinese patent with application number 201720041300.3, which discloses a single-cone spray orifice auxiliary nozzle for an air jet loom, comprising a tapered pipe body, wherein the tapered pipe body is formed by sequentially connecting an auxiliary nozzle round pipe, an auxiliary nozzle transition pipe, an auxiliary nozzle flat pipe and an auxiliary nozzle spray head unit which are communicated with each other; the outer wall of the auxiliary nozzle spray head unit is provided with a main injection unit, and seven circular spray holes with the same diameter are uniformly formed in the outer wall of the auxiliary nozzle spray head unit around the main injection unit. The technical scheme of the utility model to a certain extent to reducing the power consumption, increasing the aspect such as air current performance and improve.

SUMMERY OF THE UTILITY MODEL

For obtaining the export air current of higher speed, the better air current of bundling performance finally reaches the purpose of lower power consumption, the utility model discloses a technical scheme be, a circular cone orifice auxiliary nozzle for air jet loom, including pipe, transition pipe, flat pipe, the shower nozzle pipe that is linked together in proper order, the shower nozzle pipe be close to the terminal department and be provided with the shower nozzle group, the shower nozzle group includes a main orifice and is six auxiliary orifices of circumference array outside its circumference, the main orifice is the conical through-hole that outer aperture is less than the inner diameter, auxiliary orifice is the toper through-hole that outer aperture is less than the inner diameter, auxiliary orifice is inside and outside aperture is less than the corresponding inside and outside aperture of main orifice.

Further, the ratio of the inner diameter of the main jet hole to the inner diameter of the auxiliary jet hole to the corresponding outer diameter of the main jet hole is 1.05-2.5.

The beneficial effects of the utility model reside in that:

(1) the utility model relates to a circular cone orifice auxiliary nozzle for air jet loom has simple structure and low in manufacturing cost's characteristics.

(2) The utility model relates to a circular cone orifice auxiliary nozzle for air jet loom compares with ordinary auxiliary nozzle, especially single circular cone auxiliary nozzle, has higher export wind speed and fine air current bundling nature, and application prospect is good.

(3) The utility model relates to a circular cone orifice auxiliary nozzle for air jet loom, its main orifice all adopts the circular cone through-hole structure that the internal aperture is greater than the outer bore with assisting the orifice for export air current bundling nature is good, fast high.
