Disclosed is an anti-rotation device for a distributor inner shaft structure, comprising an upright column (1), a bracket (2) fastened on the upright column (1), two swing arms (3) arranged in opposite directions, and two connecting rods (4) arranged in parallel, wherein the upright column (1) is fixed on the ground or fixedly connected to a non-rotating base frame (300) on a filling machine, the middle parts of the two swing arms (3) are respectively hinged on the bracket (2) so as to be able to swing horizontally, and the end parts of the two swing arms (3) in opposite directions have meshing gear teeth (31). The two connecting rods (4) are located between the swing arms (3) and an inner shaft structure (100) of the distributor, one end of each is respectively hinged to the other end of the corresponding swing arm (3), and the other ends of the two connecting rods (4) are then respectively hinged to the lower part of the inner shaft structure (100) of the distributor, and are capable of swinging horizontally relative to the swing arms (3) and the inner shaft structure (100). The anti-rotation device can increase the service life of an outer ring and the inner shaft structure as well as a sealing ring located therebetween, increase the filling production efficiency and filling quality, reduce the replacement rate of corresponding components, and save on a great deal of manpower and time. |
