Main features

• Feed speed 15-23 m/min;
• Top glue pot with pre-melter for EVA/PUR glue;
• Automatic changeover to 2 different edge thicknesses by quickly pressing the corresponding button on the machine control screen;
• Automatic changeover to 4 different workpiece thicknesses by quickly pressing the corresponding button on the machine control screen (with memory);
• Infrared lamp for heating the end face of the workpiece;
• Conveyor feed with encoder system;
• edge counter;
• Reinforced conveyor;
• 5 pressure rollers with scrapers;
• Pneumatic mechanism for removing scraping chips from the workpiece;
• Two units with cleaning liquid - one in front of the jointing unit and the second in front of the polishing unit;
• Control panel "Touch screen";
• Built-in waypoint control for non-contact control of processing units;
• Possibility of programming technological breaks;
• Individual frequency converter for each working node;
• Lighting in the protective cabin;
• Limit switches on the doors in the protective cabin;
• Stock dispenser rod prevents damage to machine components during operation;
• Pneumatic shutter on the glue roller, prevents it from getting dirty;
• Adjustment of the front and rear overhangs of the edge from the control panel;
• Execution according to CE standards.
• The machine has two units for applying liquids:

1. The first unit for applying the separating liquid: with the help of 2 nozzles in front of the pre-milling unit (milling) of the workpiece. This is done by applying a special separating liquid, so that the glue residues that come out do not come into contact with the workpiece.
2. The second unit for applying polishing liquid: using 2 nozzles in front of the polishing unit. This is a cleaning fluid. The main task is to remove the anti-adhesive applied at the beginning (separating liquid) and free adhesive residues. And also to give shine to the finished edge of the part.

Engineering advantages

The bed of the edge banding machine has the form of a rigid box with the necessary stiffening ribs, which guarantees the exact location of all nodes during the entire period of operation.

The machine is controlled using a special remote control equipped with an industrial display with a “Touch screen” system. The on/off icons of units and assemblies on the display are intuitive and do not require special skills to operate the machine.

Possibility of programming technological interruptions of glue bath heating.

The wall thickness of the conveyor guide shoes has been increased to 15 mm.

The workpiece feed dispenser rod controls the minimum distance between workpieces, preventing damage to machine components during operation.

The new design of the upper beam columns of increased rigidity and special geometry, developed by the engineers of the KDT plant, provides high strength support. The movement of the pressure beam when reconfiguring the thickness of the part is more stable and even.

The jointing unit is equipped with two high-frequency motors, which ensures high-quality processing of the end face of the material before gluing the edge. Pre-milling copes with the “step” from the scoring saw, chips. The pre-joint joint is equipped with 40 mm high diamond cutters (65 mm optional).

Preheating the end face of the workpiece for better adhesion.

The pressing unit consists of 5 rollers, which are driven by pneumatics, which guarantees an even distribution of forces on the edge during gluing. Of the 4 rollers, 2 rollers have a different cone, which ensures the distribution of the clamping force over the thickness of the part. 2 cylindrical rollers apply pressure throughout the thickness of the part, and 3 conical rollers are concentrated on the lower and upper parts of the part. The powerful pneumatic cylinder of the pre-cutting knife handles the thick edge well. The rollers are equipped with a glue cleaning mechanism.

Automatic top gluing tank with pre-melting for EVA/PUR glue, 5 liter capacity. Glue is dosed and does not overheat during machine downtime. The viewing window allows you to control the presence of glue. Warm-up time and readiness for work 15 minutes.

The machine is equipped with automatic pneumatic loading of granulated glue . At the bottom of the machine frame there is a large hopper for 12.5 kg from which, through the air flow, the granules are transported to the upper hopper with pre-melt.

The end trimming unit is equipped with two high-frequency electric motors, and the movement of the saw units is carried out along special linear guides. The unit is equipped with an automatic lubrication system for the guides, as well as its own aspiration nozzle. Miter saws have a rotation angle of 0-15 degrees.

The milling unit consists of two high-frequency electric motors equipped with radius cutters, which allow processing edge material with a thickness of 0.4 - 3.0 mm. The part is tracked by two large round cams (on each motor) mounted on a floating assembly, this design prevents scrap during milling.
A new modification of copiers on the overhang milling unit and the scraping unit has a large area of contact with the part. Such copiers do not leave marks on parts with any surface, including delicate ones.
The milling unit is adjusted to different edge thicknesses and switched from the control panel.

Radial scraping with two carbide radius knives, which, after milling a 2.0 mm thick edge, remove a thin layer from the milled part of the edge, as a result we get a smooth machined surface.
The scraping unit is equipped with a mechanism for separating chips from the workpiece after scraping.
Reconfiguration of the node to a different edge thickness occurs from the control panel of the machine.

The direct scraping unit is equipped with hard-alloy straight knives (glue scraper), which carry out edge processing at the joints with the part. This operation removes excess glue and micro-roughness on the seams in the places where the edge is glued to the part.

The polishing unit polishes the processed part of the edge. For safety, the unit is equipped with additional protective covers.

The mechanism for lifting/lowering the clamping traverse is equipped with an electric drive, which ensures fast and accurate installation to the required thickness of the part.

The centralized lubrication unit automatically lubricates the guides of the trimming unit.

Electrical components of the world's leading manufacturer, Siemens, are made in accordance with CE standards.

The doors of the machine cabin are sheathed with a layer of noise insulation made from foamed polyurethane foam, which allows you to achieve comfortable work with the equipment.
