Abstract
A device for imparting vibrational energy to polymeric pellets in a feed path of an extruder is disclosed. The device includes a feed path vibrator having an elongate imparting portion for being disposed within the feed path of the extruder, and a transfer portion extending from the imparting portion. The transfer portion is configured for coupling to a source of vibration energy, and the elongate imparting portion includes at least one twisted portion along its length.
Claims22
A device for imparting vibrational energy to polymeric pellets in a feed path component of an extruder, the device comprising:
- a feed path vibrator having
- an elongate imparting portion for being disposed and vibrated within the feed path component, wherein the elongate imparting portion is a longitudinally-extending blade-like member that includes at least one twisted portion along its length, the at least one twisted portion being twisted about a central axis that extends through the blade-like member, wherein the blade-like member has opposing side surfaces that face generally outward towards the feed path component within which it resides, and
- a transfer portion extending from the blade-like member, the transfer portion being configured for coupling to a source of vibration energy.
A device for imparting vibrational energy to polymeric pellets in a feed path component of an extruder, the device comprising:
- a feed path vibrator having
- an elongate imparting portion for being disposed within the feed path component, wherein the elongate imparting portion includes at least one twisted portion along its length,
- a transfer portion extending from the elongate imparting portion, the transfer portion being configured for coupling to a source of vibration energy,
- wherein the transfer portion is a plate having an aperture extending therethrough,
- wherein the transfer portion has a plurality of dampener bores and a plurality of clearance bores extending therethrough, and a plurality of dampeners are positioned in the plurality of dampener bores wherein the transfer portion is configured to be coupled to a feed block of the extruder, and
- wherein a flange of one of the plurality of dampeners is configured to be sandwiched between the transfer portion and the feed block of the extruder;
- and
- a mounting plate, and wherein the flange of the one of the plurality of dampeners is sandwiched between the transfer portion and the mounting plate.
