• Top glue pot for EVA/PUR glue with pre-melt with automatic pneumatic loading of granular glue from a special hopper.
• Servo magazine for edge banding in 4 positions.
• Upper belt conveyor.
• Full servo reconfiguration of the milling and scraping unit from the control panel.
• Implemented the ability to automatically reconfigure the traverse to the size set on the control panel using the encoder.
• Contouring of corners from two motors.
• The machine can work 24 hours a day without stopping and process 3500-4000 linear meters/shift.
• High feed speed up to 24 m/min.
• Personal computer to control the functionality of the machine with “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.
• Lamp for preheating the end face of the workpiece.
• Lighting in the protective cabin.
• Limit switches on the doors in the protective cabin.
• Pneumatic shutter on the glue roller prevents it from getting dirty.
• Adjustment of front and rear overhangs 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 by an industrial personal computer 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 pot heating.

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

A unit for applying a separating liquid using 2 nozzles in front of the pre-milling unit (milling).

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.

Independent control of the edge feeding unit.

The machine is equipped with a servo magazine for four edges. Operation according to the machining program.

The pressure unit consists of 4 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 2 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 presser is equipped with a servo drive for precise positioning of the presser unit according to the thickness of the edge.

The machine is equipped with an upper glue pot with a pre-melt for EVA/PUR glue, with a capacity of 5 liters. 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 bed there is a large 12.5 kg hopper 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.

Full servo control. The servo-driven milling unit consists of two high-frequency electric motors equipped with diamond 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. The milling unit is adjusted to different edge thicknesses and switched from the control panel.

The rounds (profiling) unit is equipped with two motors and successfully operates at a speed of 24 m/min. The unit is equipped with diamond radius cutters. There are four schemes of node operation.

Full servo control. The scraping unit on servo drives is equipped with two hard-alloy radius knives, which, after milling the edge, remove a thin layer from the milled part of the edge and remove the kinematic wave, as a result we get a smooth machined surface. Reconfiguration of the unit from one edge thickness to another (from R2 to R1) is performed by a servo drive from the control panel.

The direct scraping unit is equipped with two 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. To give the finishing gloss to the edge, a unit for applying polishing liquid is installed.

The encoder on the mechanism for raising/lowering the clamping traverse allows you to automatically position the traverse to the thickness of the part set on the control panel.

Upper belt conveyor for a secure hold and to prevent contamination and damage to delicate parts.

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

Automatic lubrication of the conveyor is carried out by an electric pump.

The electrical components are made in accordance with CE standards.

The doors of the machine cabin are equipped with special sensors, which allows you to achieve safe work with the equipment.

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.
