20 KG HOT-MELT APPLICATORS WITH GEAR PUMP EASY TOUCH SERIES W20 The new W20 EASY TOUCH Series applicators for hot-melt adhesives with gear pump are significantly innovative in terms of simplicity of use, productive flexibility, maintenance operations and costs, speed of installation, easy programming, high safety standards, exceptional reliability and total integration with any existing assembly line. They represent a quality solution for application of thermoplastic hot-melt adhesives in several sectors. The EASY TOUCH systems are equipped with a new microprocessor with 7” LCD Touch Screen colour display, through which, with a single graphic interface showing all sections of the system (tank, manifold, hoses and guns). The operator is supported in everyday activities like managing and setting temperatures, pump control, setting machine parameters and glue sections, and integration and communication with any external units, allowing for immediate use of the system even by non-specialized personnel, without any problems involving codes or foreign languages to be interpreted. The EASY TOUCH melters have a new melting tank, entirely redesigned, to distribute the heat more evenly over the entire surface, thus obtaining a more precise and effective melt, with significant energy savings. The particularly well-finished design makes the system appreciable even in aesthetic terms. Every part of the applicator can be inspected easily by opening the practical body system. EASY TOUCH Applicators - customizable in several configurations and capable of satisfying all gluing needs - allow the operator to work in complete safety and to significantly optimize application times without wasting time uselessly. 1. NEW MICROPROCESSOR WITH 7" TOUCH SCREEN DISPLAY The following are some of the main functions of the new user interface: sequential channel heating, machine ready and pump start signals, absolute maximum temperature protection system, Economy Dual Mode, Weekly Program with Daily ECO function, colour status button with real time diagnostics and Screen Saver function, hose-gun coupling thermal regulation deactivation, LOG file for system register, Life Hours/Work Hours/Pump Cycles counter, machine parameters and Firmware updates uploaded and downloaded through a USB port, customizable system section and glue program names, and parameter Copy/Paste function. 2. GEAR MOTOR The applicators are fitted with variable speed AC motors controlled by an inverter positioned horizontally to obtain reduced overall dimensions and easy access both for inspection and maintenance, thanks to a quick connector and an easy to open body system. 3. NEW MELTING TANK WITH 20 L CAPACITY The new tank was entirely redesigned to ensure perfect efficiency in terms of melting evenness and capacity. The large loading inlet open on 3 sides makes filling easier, optimising cleaning and maintenance operations. The shaped resistance positioned on the bottom of the tank distributes heat evenly and improves thermal efficiency throughout the system, thus resulting in energy savings. The tank bottom slope (about 20°), and the melting fins - positioned parallel to the upper edge of the tank in a fan-shaped configuration - were designed specifically to melt the glue more effectively, so it can slide directly towards the pump drawing spot. The rapid discharge - located at a lower level and on the opposite side compared to the drawing spot - facilitates the collection of any impurities in the adhesive or burnt glue residue, conveying them to a single sump and preventing them from being sucked up by the pump and causing a machine shutdown, also allowing for quick cleaning operations either for maintenance purposes or to replace the adhesive. Easy to access and replace, it guarantees excellent quality of application, preventing impurities in the adhesive from clogging the nozzles. There is a wide range of available models (with single or multi-layer filtering micro-mesh, and different pitches starting from 200 micron) depending on the type of adhesive used. 5. HIGH PRECISION GEAR PUMP Gear pumps of different capacities (0,8 - 3,0 - 7,0 - 10 and 20 cc/rev) are available with the same dimensions. These pumps are absolute precise and reliable, made of fully hardened super-quick steel. Like all internal parts of the applicator, the pump is also easy to remove in case of maintenance or replacement. 6. PRESSURE CONTROL DEVICE A sophisticated control system shows the adhesive output pressure on the applicator display. This view can be combined with a traditional digital pressure gauge that shows the pressure of the adhesive in bars. 7. QUICK PRESSURE RELEASE AND REGULATION VALVE Maintains the pressure at the amount set, and ensures the utmost safety during system use. Adhesive pressure is released into the system automatically and safely, also in the event of an emergency.
