EXTRUDER TEMPERATURE CONTROLLER WITH STABLE TEMPERATURE RESET. |
摘要 |
The invention is an extruder temperature controller for an extruder barrel. The extruder temperature controller includes means for determining an actual screw speed and has means for storing a plurality of screw speeds. Each member of the plurality of stored screw speeds has a corresponding stored temperature reset value. The extruder temperature controller has a means for comparing and selecting that compares the actual screw speed to each of the plurality of stored screw speeds and selectes a default screw speed. The default screw speed has a smaller deviation from the actual screw speed than any other member of the compared, stored screw speeds. The controller further includes a means for generating a control output driver signal to the heat exchange means. The control output driver signal is the corresponding stored temperature reset value for the default screw speed. The invention further includes a means for delaying a control alarm for a predetermined time when the means for generating a control output driver signal to the heat exchange means operates at or near maximum capacity. The invention includes a method for controlling the temperature of an extruder barrel. |
