Abstract:
The present invention relates to a connection adapter for connecting two melt-guiding components having two adapter halves having connection means for connection to a respective one of the components and having connection means for connecting the two adapter halves to one another and having a melt-guiding piece that is adapted to a first of the melt-guiding components by a first opening cross-section and to the second of the melt-guiding components by a second opening cross-section. The invention furthermore relates to a melt processing plant having two melt-guiding components such as an extruder and a pelletizer that are connected to one another by such a connection adapter. In accordance with the invention, the melt-guiding piece is formed separately from the adapter halves and is tensionable against the melt-guiding components by the mutually connected adapter halves.
Abstract:
The present invention relates to a melt processing plant, comprising a melt charger for charging a processing head, in particular pelletizing head, with melt, wherein upstream of the processing head a diverter valve for discharging the melt during a starting and/or retooling phase is associated to the melt charger. According to the invention, the melt channels of the splitter head have at least one step-like cross-sectional enlargement of their inflow portion, a cross-sectional shape different from the outlet cross-section of the discharge channel, and an open orifice region out of the splitter.
Abstract:
A cutter hub position control device for consistent blade adjustment in an underfluid pelletizer is provided in connection with a motion rod attached to the pelletizer cutter hub and extending through a hollow shaft of the pelletizer motor. The cutter hub position control device can be collinear, transaxial or in a plane parallel to the axis of the motion rod to which it is attached. Adjustment of the cutter hub position control device is automated through use of feedback control mechanisms.
