Bobbin manufacturing air-valves for auto supply sergeant major device holder

摘要

In the present invention, when air is injected through a tube fitted along a spiral guide groove of an upper rotating body, the elastic support tube is pushed and resiliently expanded while being inflated, so that a yarn bundle and a bobbin, To an air bobbin holder device for yarn supply configured to be rotated in a fixed state and to be easily separated when air injected into the tube is removed.The above-mentioned feature of the present invention resides in a spindle which is continuously mounted on a support stand 2 vertically erected on a pedestal 1 at regular intervals; An upper rotating body 20 and a lower rotating body 30 coupled to upper and lower portions of the spindle 10 and supported and rotated by bearings 11; The first and second cutout grooves 51a and 51b are alternately formed in the cylindrical body so that the first and second cutout grooves 51a and 51b are alternately formed in the upper and lower rotors 20 and 30, An elastic support tube 50 extending in the longitudinal direction; A tube 41 is inserted into the helical guide groove 21 formed on the outer circumferential surface of the upper rotating body 20 and is pushed when the air is injected into the tube 41 to push the elastic supporting tube 50 to elastically expand And an air actuating part 40. A yarn bundle in which yarns are wound is inserted into the elastic supporting tube 50 so that the elastic supporting tube 50 is fixed when the elastic supporting tube 50 is opened to the outside, (30) and the elastic supporting tube (50). The air bobbin holder device for yarn supply according to claim 1,;
