Process Description:
THERM-O-TYPE 20" wide thermography equipment is a modular thermography machine, featuring electric
heaters. Machine modules include: infeed conveyor/powder module, heater module, and
cooler module. Each module has an independent variable speed conveyor drive with all
controls mounted in a single control panel.
Machine Specifications:
Heater Module:
The heater module features an independent variable speed conveyor, stainless steel
conveyor chain, 1" diameter self-aligning bearings mounted in cast iron housings with
grease fittings, and large diameter conveyor rollers. A "cleaning" roller is
mounted below the heater to remove dirt from the stainless steel conveyor chain.
The heater module is supported on four adjustable leveling feet. The heater housing
supports three, full width electric heater elements. These elements are two inch thick
ceramic fiber heaters. Each element is independently controlled by an on/off switch and
thermocouple temperature control. Each heater housing provides 113" of heat tunnel
dwell and approx, 42,000 watts of heat (with a 440/480 volt power supply). The heater housing
may be raised or lowered as required using a hydraulic lift mechanism.
Cooler Module:
The cooler module features an independent variable speed conveyor, stainless steel
conveyor chain, 1" diameter self-aligning bearings mounted in cast iron housings with
grease fittings, and large diameter conveyor rollers.
Two blowers are mounted below the conveyor chain within the "vacuum holddown"
section of the cooler module.
Two blowers are mounted on the cooler box which directs air flow on the sheet as it is
conveyed through the cooler. Both cooler blowers are equipped with filters.
The cooler conveyor can be turned on or off, and the speed can be adjusted from the
main control panel.
The cooler box may be raised or lowered as required using a hydraulic lift mechanism.
A paper eject mechanism is mounted at the delivery end of the cooler module. The paper
eject mechanism accelerates and corrugates paper to improve delivery. This is especially
helpful when running longer sheets.
A receiving tray can be mounted to the cooler module. The receiving tray angle can be
adjusted. Adjustable paper side guides and a paper stop are provided.
Powder Module:
The powder module features an independent variable speed control, stainless steel
intermediate conveyor chain, 1" diameter self-aligning bearings mounted in cast iron
housings with grease fittings, wide powder application/removal belt, and large diameter
conveyor rollers. The infeed conveyor is powered from the powder module.
Powder module speed control and vibrator on/off switch are located on the main control
panel.
A removable, large capacity powder hopper features a micrometer adjusted dual powder
flow, single lever powder flow interrupt and drop gates to restrict powder flow across
select areas across the hopper.
The vacuum pickup head features large diameter "trackless" pickup wheels. All
pickup head bearings are pre-lubricated, sealed ball bearings with exterior seals
installed on both sides of each bearing to protect against powder contamination.
There is a single point, operator side adjustment that allows the operator to vary the
space between the pickup head and the powder belt. This adjustment assures even spacing
adjustment across the pickup head and controls the total amount of adjustment.
A restriction valve is installed in the powder vacuum system. This valve allows the
operator to adjust powder vacuum.
Main Control Panel:
ThermoTech20Pro Thermography Machine main control panel is mounted on the Powder Module. This panel encases all the
electrical control components for all the modules.
Main control panel for the ThermoTech20Pro include:
- Main power switch and indicator light.
- Conveyor switch, potentiometer and speed control for infeed conveyor/powder module.
- Conveyor switch, potentiometer and speed control for heater module.
- Conveyor switch, potentiometer and speed control for cooler module.
- Infeed heater switch and temperature control.
- Middle heater switch and temperature control.
- Outfeed heater switch and temperature control.
- Vacuum blower switch.
- Powder vibrator switch.
- Emergency stop switch with safety circuit reset button.
