For putting one - component polyurethane glue on preparation, in production of laminated board and the bearing beams.
Device and principle of work:
Size node of stationary type, with automatic system of lock of glue jets in idle time of installation or shutdown of power supply.
This system prevents reaction of glue in glue jets that excludes need for regular cleaning of the equipment and allows to work comfortably in the manual and automatic modes.
Automatic closing of lock happens at shutdown of power supply or pause in operation of the machine more than 3 minutes (time is adjusted depending on characteristics of the used glue), manual - closing with pressing of the corresponding key control panels.
The glue pump is made from high - quality steel with high - precision processing of surfaces of working zone, axial and radial gaps between mobile parts of the pump - no more than 6 microns. Lack of glands, laying, plugs, bearings does operation trouble - free and allows to use different modifications of 1 - K polyurethane systems.
Adjustment of supply of glue is carried out by means of the controller and frequency converters with vector system of work. At change of viscosity of glue, the pump torque is automatically adjusted that allows to pump over exact amount of glue + / - 5gr/sq. m), designated by technological process, leveling difference of its viscosity.
The following adjustments are provided:
- amounts of glue 0 - 200 gr/sq. m; (it is controlled by electronic flowmeter with indication of expense on one zago of number of preparations);
- speeds of drawing 0 - 50 m/min;
- manual or automatic operating modes;
Installation is equipped with the newest intellectual system of capture, positioning and transportation of preparation depending on conditions of technological process.
Defects in geometrical amount of preparations are leveled by system of air clamps and do not influence installation work accuracy.
This system does not need liveroller tables and can use any parasitic roller conveyers.
The configuration with the multi - speed mode of the conveyor, allows to exclude prokapyvaniye gluing between preparations, ensures safe functioning at removal and giving of preparation on the receiving roller conveyer, in combination with the high speed of drawing.
