CSC Servo Knife Cutters UGE047/1003
2-4 DESCRIPTION
Extruded material that has been sized and cooled enters the
cutter from the upstream side (see How the Servo Cutter
Works continued, Section 2, step 1). Typically, a puller is
placed just before the cutter; the puller pulls the extrudate
through the sizing and/or cooling tanks and feeds it into the
cutter.
The positional servo motor, is direct coupled to the cutter
head, or an in-line planetary gear reducer that drives the cutter
head. The planetary gear reducer arrangement increases cut-
ting torque, improves servo motor efficiency, and offers
improved bearing load ratings.
The cutting knife, attached to the cutter head, is driven by the
servo motor (see How the Servo Cutter Works continued,
Section 2, step 2). Two cutter bushings guide and support both
the extrudate and the cutting knife. The cutter head is mounted
directly to the in-line planetary gear reducer shaft using a
Trantorque coupling device, and may have as many as four
optional blade positions.
Two types of cutting modes are available. On-demand cutting
modes (Timer, Encoder, Auto and Product) provide a single
rotation cut cycle. However, in continuous cutting modes
(Flywheel and optional Follower) the cutting mechanism
rotates continuously.
The knife guard includes a stainless steel lower tray, which
can be used for blade lubrication. The upper knife guard
includes a clear polycarbonate window. This allows you to
watch the cutting blade during operation.
Cut pieces are collected or carried on to further processing by
an optional conveyor (see How the Servo Cutter Works contin-
ued, Section 2, step 3).
