Main features
- Max. width of the pack depends on its height
- Polyester infeed-outfeed conveyor belt with high friction coefficient. Product centring guide.
- Sealing bar with cutting blade actuated by a pneumatic cylinder (no type of emission during the sealing stage)
- Height of work surface: 850 +/-25mm
- The temperature of the sealing bar and the tunnel is controlled with PID thermostats
- Safety photocell that blocks the sealing blade if it detects an obstacle in its path
- Automatic upper and lower system to unwind the film reel with dragging rollers
- Max diameter of the heat-shrinking film reel 350 mm – thickness between 35 and 100 microns
- Heat-shrinking tunnel insulated with rock wool and heated with resistors. Forced ventilation system with air circulation.
- Conveyor belt of the heat-shrinking tunnel in thin steel mesh with a speed adjustable gear motor
- Machine with a Siemens S7 PLC and TP 177 Operator panel
- Voltage supply: optional choice between 3-phase 220V & 3-phase 400V+ Neutral
- Air consumption: 100 NL/min for simple models 200 NL/min for fast models. Compressed air required 6 bar
- Switch to exclude all other machine operations and use it as a conveyor belt
- Switch for the machine use cycle change in automatic, manual/semi-automatic mode with pedal-start
Optional features
- Guides for product containment after the sealing bar
- Side guides to protect the product installed inside the tunnel
- additional 400 mm of insulated hood positioned at the outfeed of the heat-shrinking tunnel
- Photocells at the tunnel outfeed to accumulate packs and prevent them from being blocked inside the tunnel
- Self-sizing mechanical presser on the pack for unstable products
- Film presser rollers
- Electric winch to lift the upper film reel
- Pneumatically lifted dragging film roller to facilitate reel change operations
- Machine mounted on wheels
- Section of the conveyor with thick rollers positioned below the pack cooling unit at the outfeed of the heat-shrinking tunnel. This station is ideal to group products which are only packed with film
- Sealing bar height set automatically
