- Fully sealed system
- Glue tank with special non-stick coating
- Thermal insulation and protection from overheating
- Compact dimensions
Purpose
PUR Hot Melt Pre-Melter KDT PUR-2.5C is used with KDT edgebanding machines equipped with gluing units for PUR adhesive. PUR adhesive, in factory-packaged cores, is placed in a special tank with a heating element at the bottom. The melted adhesive at the bottom of the core is forced by an upper pneumatic cylinder through an opening in the chamber floor by a moving pressure disk and into an intermediate tank, where it remains heated and liquid. As needed, a gear pump delivers the required amount of adhesive through a heated hose into the edgebanding machine.
Main features
- A completely sealed system prevents the polymerization of PUR adhesive during work breaks of up to several days.
- Uninterrupted supply of PUR glue for several hours.
- The control system allows you to program the melter for any conditions.
- Cost reduction due to the advantageous form of adhesive production.
- Can be used with two edgebanding machines KDT thanks to two glue supply channels (second hose optional).
- The working tank and intermediate tank can be individually adjusted.
- Glue reservoir with special non-stick coating.
- Empty glue bath alarm thanks to the glue level sensor.
- Thermal insulation and protection from overheating.
- Compact dimensions.
Engineering advantages
PUR Hot Melt Pre-Melter is equipped with a color touchscreen, physical buttons and knobs, a programmable logic controller, and inverter control. The control system doses the adhesive and monitors the temperature of the adhesive tank and hose, as well as operates the pneumatic cylinder. Settings vary depending on the adhesive type, workpiece material, and ambient temperature. Adhesive delivery can be performed in both manual and automatic modes.
The adhesive tank is an aluminum structure consisting of a tank and a base. The base of the adhesive tank is equipped with a heater. The heated base melts the adhesive, and the heating temperature is regulated by a temperature control system. During operation, a moving pressure plate reduces the adhesive level and compresses it to ensure full contact with the heating base. The moving pressure plate is equipped with a special sealing ring; when pressure is applied, the adhesive tank is sealed to prevent air from entering. The surface of the adhesive tank has a special non-stick coating. When the adhesive level in the tank is low, an indicator lights and an audible signal sounds.
The adhesive is fed by a gear pump through a heated hose into the edgebander.
Can be used with two edgebanding machines KDT (hose length 4 meters).
