[0028] The embodiment of the utility model discloses a negative pressure pipe for spinning.

[0029] According to the drawings Figures 1-6As shown, it includes a negative pressure tube body 1, a fixing hole 11 opened on the outer wall of the negative pressure tube body 1, a recovery box 2 arranged at one end of the negative pressure tube body 1, a connecting pipe 21 arranged on one side of the recovery box 2 and a fan 3 connected to one end of the connecting pipe 21. The negative pressure tube body 1 is mainly used in spinning equipment. Specifically, when the fan 3 is turned on, a pressure environment lower than the external atmospheric pressure is formed inside the negative pressure tube body 1. During the spinning process, due to the pressure difference between the inside and outside of the negative pressure tube body 1, the surrounding air will carry impurities such as flying flowers and dust and be sucked into the inside of the negative pressure tube body 1 through the fixing hole 11. Then, the air with impurities is transported to the inside of the recovery box 2 under the action of negative pressure. After filtering, the clean air is discharged and the impurities are collected in the recovery box 2, thereby achieving the purpose of cleaning the spinning working environment and improving the yarn quality.
