Abstract
A plastic melt machine includes a feed screw rotatably mounted in a barrel and driven in rotation about a longitudinal screw axis of the feed screw by a screw drive to plasticize material, and an apparatus for driving a device independently of the feed screw. The device can be any rotatable device associated with the feed screw wherein the device is rotatable about a drive axis and is in fluid communication with the barrel to receive the plasticized material. The drive axis is one of parallel to and offset from the screw axis and extending at an angle relative to the screw axis. A drive shaft couples the device to the device drive for rotating the device independently of the rotation of the feed screw by the screw drive.
Claims20
An apparatus for use in a plastic melt machine, the apparatus comprising:
- an adapter block being in fluid communication with a barrel of the plastic melt machine to receive material plasticized by rotation of a feed screw rotatably mounted in the barrel;
- a device positioned in the adapter block and being rotatable about a drive axis offset from a longitudinal screw axis of the feed screw;
- and
- a device drive coupled to the device for rotating the device independently of the rotation of the feed screw by a screw drive of the plastic melt machine.
An apparatus for use in a plastic melt machine, the apparatus comprising:
- an adapter block being in fluid communication with a barrel of the plastic melt machine to receive material plasticized by rotation of a feed screw rotatably mounted in the barrel;
- a device positioned in the adapter block and being rotatable about a drive axis offset from a longitudinal screw axis of the feed screw;
- a drive shaft coupled to the device;
- and
- a device drive coupled to the drive shaft for rotating the device independently of the rotation of the feed screw by a screw drive of the plastic melt machine.
An apparatus for use in a plastic melt machine, the apparatus comprising:
- an adapter block having a passage in fluid communication with a barrel of the plastic melt machine to receive material plasticized by rotation of a feed screw rotatably mounted in the barrel;
- a device positioned in the passage and being rotatable about a drive axis offset from a longitudinal screw axis of the feed screw;
- a drive shaft coupled to the device;
- and
- a device drive coupled to the drive shaft for rotating the device independently of the rotation of the feed screw by a screw drive of the plastic melt machine.
