Abstract
The invention discloses a negative-pressure jointing bobbin comprising a bobbin body. A plurality of negative-pressure holes are uniformly formed in an annular jointing area of the bobbin body. A negative-pressure cavity is formed inside the bobbin body in correspondence to the annular jointing area and is communicated with the negative-pressure holes. Air in the negative-pressure cavity is sucked to form negative pressure. A negative-pressure adsorption area is formed in the annular jointing area. Yarns are adsorbed in the annular jointing area under negative pressure. Negative pressure is formed in the negative-pressure cavity by a suction fan, and the negative-pressure holes in the wall of the bobbin body are used for adsorbing the yarns so as to facilitate automatic doffing jointing, so that the automatic doffing jointing rate is up to 100%, labor intensity is reduced, no yarns are left, and utilization rate of roving yarns is greatly increased.
Description
Technical field
