Main features

• Feed speed 20-26 m/min;
• Magazine for edging material for 4 types of edges;
• Automatic stops in conveyor pads for positioning the part at 90 °;
• A jointing unit with a double chopper for high-quality preparation of the workpiece before gluing;
• Upper glue bath for working with EVA/PUR adhesives;
• A pressure tape instead of rollers guarantees precise positioning of the part at all stages of edge processing at a speed of 26 m/min;
• 4-motor unit rounds;
• “Touch screen” control panel based on WINDOWS 10;
• Pneumatic adjustment for different edge thicknesses from the control panel;
• Programming technological breaks in heating the glue bath;
• Individual frequency converter for each working unit;
• Lighting in the protective cabin;
• For safety, the machine is equipped with an electronic cabin door locking system;
• The mechanism for raising/lowering the clamping beam is equipped with an electric drive, which ensures quick and accurate installation to the required thickness of the part;
• A locating ruler with a digital counter guarantees quick and accurate setting of the required removal on the part during milling at the jointing unit;
• A pneumatic curtain on the glued application roller prevents it from becoming dirty;
• Adjustment of front and rear edge overhangs from the control panel.
• The machine has two liquid application units:

1. The first unit for applying the separating liquid: using 2 nozzles in front of the unit for preliminary milling (jointing) of the workpiece. This is when a special release liquid is applied; any remaining glue that protrudes outward does not come into contact with the workpiece.
2. Second unit for applying polishing liquid: using 2 nozzles in front of the polishing unit. This is the cleaning fluid that is applied. The main task is to remove the release agent (release liquid) applied at the beginning and any loose adhesive residues. And also to add shine to the processed edge of the part.

Engineering advantages

The bed of the edgebanding machine has the shape of a rigid box with the necessary stiffening ribs, which guarantees the exact location of all components throughout the entire service life.

The machine is controlled using an industrial personal computer with a “Touch screen” system. The on/off icons for components and assemblies on the display are intuitive and do not require special skills to operate the machine.

Possibility of programming technological breaks in heating the glue bath.

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

The edge feed magazine for 4 types of edges simplifies and speeds up the process of changing edges and switching to another thickness, width, color.

Automatic stops in the conveyor pads push the panel and enable precise 90 ° positioning.

The jointing unit is equipped with a double crusher, which allows you to format the panel, removing up to 5 mm material on each side and formats without damaging the pre-processed side.

Preheating of the workpiece end for better adhesion.

The pressure unit consists of 5 rollers, which are driven pneumatically, 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 pressing force across the thickness of the part. 2 cylindrical rollers apply pressure throughout the entire thickness of the part, and 3 conical rollers are concentrated on the lower and upper sections of the part. The powerful pneumatic cylinder of the pre-cut knife successfully copes with thick edges.

The machine is equipped with an automatic top glue tank for PUR/EVA glue with pre-melt glue, with a capacity of 5 liters. The glue is supplied in doses and does not overheat during machine downtime. The viewing window allows you to monitor the presence of glue. Warm-up time and readiness for use is 15 minutes.

The end trimming unit is equipped with two high-frequency electric motors, and the saw units move along special linear guides. The unit is equipped with an automatic lubrication system for the guides.

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 using two large round tracers (on each motor) mounted on a floating unit, this design prevents defects during milling. The machine is equipped with two pairs of milling units - 2 roughing units and 2 units for finishing milling of overhangs. Each milling unit is set to two edge thicknesses and is switched from the control panel.

The rounding (contouring) unit is equipped with four high-speed motors and operates successfully at a speed of 26 m/min. The unit is equipped with diamond radius cutters. There are four possible operation schemes for the unit.

Radial scraping with two carbide radius knives, which, after milling an edge 2.0 mm thick, remove a thin layer from the milled part of the edge, resulting in a smooth machined surface. The nodes are switched on from the control panel of the machine.

The direct scraping unit is equipped with carbide straight knives (glue scraper), which process the edges at the joints with the part. This operation removes excess glue and micro-irregularities on the seams where the edge is glued to the part.

The grooving milling unit is equipped with a groove saw with carbide tips for milling a groove for the rear wall. One of three options for positioning the milling unit is possible: for milling a groove from the top, bottom, or at the end of the part.

A double polishing unit polishes the processed part of the edge; high quality is achieved through an oscillation system driven by pneumatic cylinders. To impart a final shine to the edge, a unit for applying polishing liquid is installed.

A pressure belt instead of rollers guarantees precise and reliable positioning of the workpiece during all stages of edge processing at a speed of 26 m/min.

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

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

Electrical components are made in accordance with CE standards.
