Main Power
Switch
Turns on/off the power to the entire machine. Maintains all previously
set tunnel adjustments which assures rapid start up and consistent
quality at the beginning of your next shift.
Heater Switch
This switch allows the heaters to be shut off at the end of your
production run without having to change temperature settings.
This expedites start up and assures quality control. In addition,
it facilitates machine “cool down" by allowing the
tunnel fans and conveyor to run until cooled.
Variable Speed Conveyor Control
Allows you to adjust the conveyor speed to obtain the best quality
“shrink" for your products regardless of their size
or shape.
Digital Temperature Control
Insures consistent and uniform shrink quality by virtually eliminating
any temperature fluctuation within the shrink tunnel. Presents
a dual display read-out of both actual and set-point temperature
to provide an accurate visual indication of tunnel temperature
conditions. An added benefit of digital control is it minimizes
setup and changeover time to further increase productivity.
(Not available on the STC 2016 "ECO".)
Adjustable Fan Speed Controls
Allows independent adjustment of air flow over all surfaces of
your package. This assures quality shrink packaging plus maximum
flexibility, no matter what the size or shape of your product.
(Not available on the STC 2016 "ECO".)
Teflon Mesh
Conveyor Belt
This durable, non-stick belt is ideal for very small packages
or multi-packs. The design of the mesh belt facilitates even air
flow to all surfaces of your package and is essential when your
product must be transported smoothly through the tunnel.
Live
Roller Chain Conveyor
This
conveyor is composed of 3/8” diameter rods, sleeved in silicone
rubber and assembled on 1-1/2” centers. Useful for packages
heavier than 5 to 7 pounds which may tax the Teflon mesh conveyor
belt and for applications where optimum shrink quality is required.
(Not available on the STC 2016 "ECO".)
Hi-Density
Live Roller Chain Conveyor
Similar
to the conveyor previously described, the conveyor rods are mounted
on 1” center-to-center spacing. Recommended for packages
where there is concern of the product falling within the roller
spaces.
(Not available on the STC 2016 "ECO".)
Lighted Viewing
Window
Allows for faster set up and easy adjustment of controls to enhance
packaging quality and productivity. It’s great for contract
packagers or companies with in-house tours to demonstrate to customers
how you monitor quality and productivity on a continuous basis.
(STC 2520 only.)
Tunnel Curtains
Double silicone rubber re-inforced curtains form fit around your
packages. This minimizes heat loss and maintains tunnel temperature
accuracy and consistency to assure quality shrink packages.
Constant and
Impulse Sealing
This switch allows the operator to choose the optimum sealing
condition necessary to produce fast, strong seals depending on
which commercially available film is used.
(Constant heat sealing is NOT available on the STC 2016 "ECO".)
Impulse Time
This time control monitors how long the element wire gets hot.
Seal Wire Heat
Adjust
This control determines how fast and how hot the seal wire will
get, allowing for maximum sealing speeds.
Sealing Wire
Sensor
This unique switch prevents the sealing wire from overheating
during the seal cycle. By sensing the correct seal wire temperature,
fast, clean seals are obtained. You can expect longer seal wire
life and reduced wear and tear to the sealing head assembly with
this proven Belco System.
Hot Knife Sealing
Technology
Two Watlow digital temperature controls adjust the heat to the
front seal knife and the side seal knife for fast, clean sealing
which is accurate and repeatable. The adjustable dwell time control
monitors how long the seal knives are in contact with the film.
(Not available on the STC "ECO".)
Film Roll Cradle
No tools are necessary to quickly change film rolls or sizes.
This heavy duty film cradle has adjustable side guides to position
the film and a film unwind brake to adjust how fast the film unwinds.
A film splitter bar helps open the center fold film.
Infeed Tray
The aluminum infeed tray with Film Opening Horn assures easy product
loading into the film, maximizing your productivity and minimizing
operator fatigue.
Seal Arm Guards
These guards clamp the film in an even and positive manner to
reduce film tension during the sealing process and help insure
quality seals.
Magnetic Clamps
Rather than using adhesive tape, magnetic clamps allow your operator
to quickly change and maintain the bottom seal sponge and Teflon.
In addition, it allows for flipping and reversing both of these
wear items to prolong their life and lower your operating costs.
Adjustable
Tilt Sealing Table
The product sealing table or optional take-away conveyor can be
raised, lowered or tilted to allow smooth transfer of your product
out of the seal area and into the tunnel.
Heavy Duty
Locking Casters
Belco STC’s are mobile. You’ll find them easy to move
from one production location to another assuring maximum production
flexibility and productivity. Leveling pads are standard on all
models.
Welded Frame
Belco STC’s are built to last. You can depend on years of
trouble free production. All Belco Sealer-Tunnel Combinations
start with the same premise…a heavy wall tubular steel welded
frame. Solid...nothing to loosen up…nothing to become misaligned
and cause unnecessary wear and downtime.
Standard
Options:
Magna-Lock
Sealing Arm System
Powerful magnets hold down the seal arm to provide semi-automatic
operation and even seal pressure along the entire seal base. The
adjustable timer provides the correct dwell time necessary to
assure consistent, strong, quality seals.
Air-Operated
Seal Arm
Dual Opto-Touch start switches begin the seal cycle and greatly
reduce operator fatigue while creating the best seals possible
in semi-automatic mode.
PLC
Controlled Operation
Once the dual Opto-Touch start switches initiate a seal cycle,
the PLC program lowers the sealing arm under low pressure. When
the seal arm reaches the base, valves switch to high pressure
for the sealing cycle.
Power
Take-Away Conveyor
Once the seal is complete, the arm raises and the product is transferred
out of the sealing area. An adjustable timer controls how long
the conveyor moves the product, either all the way out of the
seal area or just far enough to make the next package.
Powered
Film Unwind
This motorized film cradle feeds film to the operator upon demand
as the package is advanced into the seal area. Regardless of how
fast the operator or how long or small the product size, this
option can maximize production speeds while minimizing operator
fatigue.
Adjustable
Film Inverting Head
By turning film inside out in a 90° manner, an in-line packaging
operation can be created to significantly increase production
flow, lessen product handling and increase operator efficiencies.
The adjustable height inverting head opens the film for the operator
to help reduce fatigue. This feature also minimizes the amount
of film required to wrap your package and eliminates the need
to buy additional fixed heads for your other package sizes.
Hole
Punches
Air evacuation devices come in several styles to best fit your
machine and application. Choose pin-wheel, thermal, electro-magnetic,
air or multiperf for your machine.
