The alignment of one air admission hole communicates, and the second venthole is aligned with the bottom land of outer groove and communicated, and the second air admission hole, the second venthole pass through company
Through hole inside spindle is communicated, and rotary body is set by the support rotary of left and right bearing located at the cylindrical of connecting shaft, rotary body
Connect the first venthole of air outlet adapter and inner groove is set in bore area, the first venthole is directed at phase with the bottom land of inner groove
Logical, the cylindrical fixation of connecting shaft of the sealing shroud between the bearing of left and right is arranged, the endoporus of the cylindrical and rotary body of sealing shroud it
Between formed and be rotatably assorted, the sleeve side walls of sealing shroud are set through inside and outside middle stomata and in the cylindrical table of middle stomata both sides
Face sets seal groove, sets O-ring seals in seal groove, middle stomata is penetrated the outer groove and inner groove.
It is first air admission hole, the second air admission hole, the first venthole, the second venthole, through hole, middle stomata, outer groove, interior
Annular groove setting is multigroup, between every group independently of each other.
Using the full-automatic banding machine Pneumatic rotary joint of above-mentioned technical proposal, fixed body is fixedly mounted, and rotary body with
Rotatable parts and rotation cylinder synchronous axial system, during work, after inlet suction port supplies to the first air admission hole, pressure gas source will be by
Order passes sequentially through the second air admission hole, through hole, the second venthole, outer groove, middle stomata, inner groove, the first venthole, most
Rotation cylinder supply is sent out to from air outlet adapter afterwards, it is simple in construction so as to more preferably meet the air supply requirement of banding machine rotation cylinder,
O-ring seals play sealing function.
