Universal edge banding machine KDT-305MC for PUR/EVA glue with milling unit and vacuum workpiece fixation

Purpose

The KDT-305MC universal edge banding machine featuring a quick-change glue pot system for PUR/EVA adhesive, is designed for precise, high-speed edgebanding of straight and curved workpieces, followed by mechanical finishing by milling and scraping. Workpieces are fed through the edgebanding unit using hot-melt adhesive applied by a roller, either automatically via an automatic feeder or manually.

The glue pot is interchangeable with the upper pots of the KDT automatic edgebanding machines and is also compatible with the glue pot cleaning and storage system.

Precise edge trimming is performed automatically using a laser sensor for a higher-quality joint. The edgebanding material is fed manually into the machining unit. Processing is performed by two milling and scraping units: one from below and one from above.

Distinctive features

• Gluing of curved and straight parts in manual (pedal) or automatic mode (by counter).
• Milling and scraping of curved and straight parts in manual mode.
• Removable upper glue pot for working with PUR/EVA glue.
• Convenient fixation of the workpiece on the work table using a vacuum.
• Functional touch control panel with the ability to adjust all machine parameters.
• Milling and scraping unit with photoelectric sensor.
• Workpiece blowing systems on gluing and milling-scrapping units.
• Automatic workpiece feed device.
• Pneumatic edge trimming using a pneumatic cylinder with a guillotine knife.
• The edging material is fed into the gluing area automatically from the edging magazine.
• The feed speed is regulated by an inverter - 1-10 m/min in automatic mode and 1-18 m/min in manual mode.
• An air preparation unit with a moisture separator and an oiler for automatic lubrication of the entire pneumatic system of the machine.

Design advantages

The replaceable upper glue pot allows for working with PUR/EVA adhesives and changing the glue color. The pot is interchangeable with the upper pots of KDT automatic edgebanding machines.

The machine control panel is convenient and intuitive, with all machine controls concentrated in one place.

The laser sensor allows for precise (±0.3 mm) edge trimming for a higher quality joint for straight workpieces with a length of 400 mm and more, and for curved workpieces with a diameter of 300 mm and more.

The vacuum table allows for convenient and effortless movement of workpieces through the machine's working units. The feed table vacuum can be turned on and off using either the remote control or the foot pedal.

The automatic workpiece feeder minimizes operator intervention, eliminating human error from affecting quality. The automatic feeder automatically adjusts to the desired workpiece thickness, accelerating and decelerating when processing corners. This device is especially useful when working with large workpieces. An additional roller monitors changes in the workpiece's shape and applies additional pressure at bends to ensure maximum adhesion quality.

The milling and scraping unit is automatically set to the required thickness of the workpiece and is equipped with waste removal pipes.

The unit includes:

• Milling unit for removing edge overhangs.
• Nozzles for spraying cleaning liquid.
• An optical sensor monitors changes in the workpiece's shape (turns, angles, straight sections), thereby decreasing or increasing the workpiece feed rate. This increases the efficiency of the entire machine and the quality of edge processing.
• Scraping unit for removing adhesive residue.
• Nozzles for blowing the workpiece surfaces are necessary to reduce resistance and prevent damage to the workpiece surface when it is moved during edge processing.

Electrical components are manufactured according to CE standards using the best components.
