The invention concerns a device for opening blown plastic bottles that are hermetically closed by a dome (5) and mounted in holding means in a duct (7) by cutting the dome (5) using a cutting knife (32) mounted in a cutting head (1) that can move relative to said dome along the periphery thereof. In order to enable a precise cut under aseptic conditions, said opening device is characterized in that the holding means (15, 18) have at least two centering fingers (18) which can move radially relative to the duct (7) for the purpose of engaging with the part of the dome (5) that is to be cut off, said centering fingers being mounted closer to the end ( 17) on side of the bottle than to the cutting knife (32).
Abstract:
The machining unit consists mainly of three essential elements which are the rotor, the phase shifting device and the device for driving the tools. The rotor (100) comprises a rotating shaft (1) and is provided, for instance, with four borings parallel to the rotation axis in which the cutter-holder axles (9a, 9b, 9c, 9d) are mounted. The infeed of the cutters into the material to be machined is controlled by the displacement of a control bush (19) bearing at its end two ellipsoid surfaces (20a, and 20b) arranged for co-operating with the helical surfaces (14a, 14b, 14c, and 14d) of the control levers integral with the tool block. The control bush can have two extreme positions and a median position. A phase shifting device comprising a pulley (22) mounted loose on a shaft (31) and a return pulley (25), enables the angular offsetting of the control bush (19) with respect to the cutter bar.
