The yarn outlet 111 of the body 11 is discharged. Moreover, the cavity of the nozzle and the housing, the yarn inlet port of the nozzle and the yarn outlet of the housing can simultaneously accommodate a plurality of raw filaments or bobbins arranged side by side horizontally and vertically.

The inlet pipe 13 is connected to the side wall of the nozzle through the gas guide channel 122, and the connection between the gas guide channel 122 and the nozzle 12 is inclined toward the air outlet of the nozzle 12. Guided by the channel 122 , the compressed air flows toward the air outlet of the nozzle 12 and enters the housing 11 , and is ejected from the yarn outlet 111 of the housing 11 . Certainly also can make inlet pipe 13 directly link to each other with nozzle 12, and the connection place of inlet pipe 13 and nozzle 12 is inclined towards the air outlet of nozzle 12, as long as the compressed air that can make inlet pipe 13 enters is guided toward the air outlet of nozzle 12 is OK.

In the present invention, the shell of the nozzle 12 is thicker, and in the shell of the nozzle 12, an outer cavity 121 outside the nozzle cavity is set, and the air inlet pipe 13 is connected to the outer wall of the nozzle 12 and communicates with the outer cavity 121, and the outer cavity 121 is connected with the outer cavity. A gas guiding channel 122 is provided between the cavity of the nozzle 12 , so that the compressed air first enters the outer cavity 121 through the air inlet pipe 13 , and then enters the cavity of the nozzle 12 through the gas guiding channel 122 . In the present invention, the air outlet of the nozzle 12 and the gas guide channel 122 are made into a gradually expanding type, so as to conveniently set the gas guide channel 122 and guide the compressed air into the casing. The present invention utilizes the suction generated by the negative pressure formed when the compressed air enters the nozzle 12 and the housing 11, so as a preference, in order to make the compressed air enter the nozzle 12 more uniformly and form a better negative pressure, the present invention along the outer cavity 121 For a week, a plurality of gas guide channels 122 are provided. After compressed air enters the outer cavity 121, it can enter the cavity of the nozzle 12 through multiple gas guide channels 122 at the same time, fill the cross section of the cavity of the nozzle 12, and quickly form a negative pressure.

When beating with a spinning machine, place the glass fiber precursor or bobbin at the yarn inlet port of the nozzle 12, strip the outer layer head of the raw silk or bobbin and face the yarn inlet port, and pass it to the air inlet pipe 13. Because the compressed air flows at a high speed, when entering the nozzle 12 and flowing into the casing 11, a negative pressure is formed in the cavity inside the nozzle 12 and the casing 11, thereby generating suction, and the outer layer of the original yarn or bobbin will be Due to the effect of suction, it is sucked into the nozzle 12, and after entering the cavity of the casing 11, it is blown out from the yarn outlet 111 of the casing 11 under the blowing force of the compressed air, so that the outer layer of the original yarn or bobbin can be stripped. The cavity cross section of the nozzle 12 and the housing 11, the yarn inlet port of the nozzle and the yarn outlet of the housing have a certain size, and under sufficient air pressure, the outer layers of a plurality of raw filaments or bobbins arranged side by side can be simultaneously It enters into the yarn inlet port horizontally or vertically and blows out from the yarn outlet, so the beating machine can simultaneously beating multiple raw yarns or bobbins with high beating efficiency.
