| Description | LINE 2:
Davis-Standard Extruder, 1.5" 30:1 L/D, 2018 yr.
It was an occasional use development machine, so it has very little run time.
It is a complete system. Extruder, melt pump gearmotor, electrical panel, HMI, and several downstream heat zones.
Because this extruder was on a mezzanine, the main HMI is on the face of the main electrical panel. The duplicate HMI was installed on the level below. Both HMI screens are 19" touchscreen for easy visibility and use.
The extruder power is 480 V, 3 phase, 119 FLA. The downstream zones are 240V single phase, protected by GFCI breakers. I will include the 480V 3 phase to 240V single phase transformer. The downstream zone detail is shown in picture one below. All of the heaters are individually wired to the 5 pin Harting plugs/receptacles. This allows quick/safe replacement of a failed heater while the extrusion system remains running.
The extruder centerline is about 44". However, because it is on casters, tracks, and has levelers, the CL can be adjusted down about 3", and adjusted up as much as wanted.
Water cooled material feed section.
The extruder is a 5 zone unit. Heat/cool. Air cooled.
The gearbox has 17.42 ratio, so the maximum standard screw speed is 100 rpm.
The control system is the Davis-Standard eVUE PLC-based control system. This provides excellent temperature and speed/pressure control.
It also has advanced control, communication, trending, etc., capabilities.
The extruder motor is Marathon brand, 15 HP, 1750 std rpm, variable speed. Allen Bradley Powerflex 753 drive in the control panel.
The melt pump is Marathon brand, 5 HP. It is missing. Allen Bradley Powerflex 753 drive in the control panel.
Overhead melt pump support with drive shaft and guard.
I can provide a Mahr two outlet melt pump.
Nordson EM-15 screen changer.
Drawer magnet box at the feed section.
Extruder screw.
There is one pressure control zone (melt pump inlet pressure), with 6 pressure monitor points. We typically use Dynisco pressure transducers.
The extruder is on casters. One side V casters. One side flat casters.
The melt pump gearmotor is on a machine direction adjustable slide. This allows for different melt tooling lengths and configurations.
RETECH Flexible Draw Stand, 3 pairs of godets + (3) pairs + (2) godets. (Larger godets than unit in Line 1)
(1) OERLIKON BARMAG WinTens 904 Winder, 2018 yr, 94mm chuck. Previously ran 2 & 4 ends up of 200 den multifilament mostly at 3000 m/min but ran some at up to 4000 m/min.
Previously installed on mezzanine but is currently dismantled and in storage.
Spare parts included as available. |
