PVC High Glossy Edge Banding Extrusion Line, Roma Edge Banding Extruder and Printing Line (0.4-2.0mm)

Introduction

YBW3600 Type Three-color Printing & UV glazing machine for edge band

(Designed for offline)

1. Design condition:

① This line is used to printing patterns and coating UV lacquer on the surface of wider PVC/ABS edge band.

② It can coat different UV varnish to get different effect like Matt, shine and high gloss, but high gloss effect is not good to slit, so better use it by whole sheets.

③ The effective printing width is 100~500mm, thickness of rolling material is: 0.3-1.2mm.

④ It adopts solvent printing ink and UV lacquer

⑤ Total 3-colors, one is background color, 2 is wood grain designs colors.

⑥ Speed V=2-15m/min.

2. The whole line consisting of:

- 1x double unwinding station

- 1x Haul-off station

- 1x background printing station

- 2x decoration printing station

- 2x 1.2m blow heating units for decoration printing

- 2x 3m blow heating units for decoration printing

- 1x UV lacquer coating station

- 1x UV curing station

- 2x haul-off stations (one set with water-cooling devices)

- 1x double rewinding station

- 5x pneumatic pumps

- 1x central PLC control system for complete line

Technical parameter of YBW3600

3. Basic assembly of each unit and performance:

Part one: Unwinding Station

► It is used to unwinding the edge band rolls into printing line, with double unwinding shaft for easy change edge band rolls;

► Unwinder adopts brake to unwinding rolls;

► the aperture diameter of unwinding shaft is 76mm(we can make per your requirement);

► the max outside diameter for unwinding roll is 600mm;

►the center height is 800mm;

(one shaft is 76mm, one shaft is 200mm, please confirm your EB roll diameter before order, thanks.)

Part Three: Background Printing Station

► it is used to printing base/background color on the bottom of PVC edge bands. Normally the extruded EB could not match the design wooden color very much, so it needs to printing base color on the EB, which can make top wooden grain design more vivid like true wood grains.

► we adopt double-roller station to printing base color, it can complete cover white color of EB into other colors like brown, black, red and etc. Just for EB, it’s better to make extruded EB with some colors which is near its printed designs, that will look more vivid. At that time, you can adopt one-roller station to printing base color, it’s more flexible.

Part Five:Design Printing Station (2units)

► It is used to printing wooden grains patterns or other patterns on the surface of PVC edge bands.

► It needs to make design cylinders, and install design cylinder on the machine. When machine running, the patterns from design cylinder will connect to PU rubber roller, the PU rubber roller will connect to edge band, the patterns will be transfer printed on the EB by inks.

► The different patterns will be engraved on their own cylinders, it’s an investment. You may offer us the pattern samples, we can make it per your sample for you.

Part Six: UV coating unit (three-rollers)

► It is used to coating UV lacquer on the top of EB, which can get matt, shine and high gloss effect, and also it can protect design inks no fading and anti-scratch.

► Total three-roller station, if you want Matt or shine effect only, you can adopt first station to coating matt UV lacquer, if you want high gloss effect, you can adopt second and third station to coating high gloss UV lacquer.

Part Seven: IR heating & drying

► It is used to heating and melting UV lacquer by IR lamps, and also the solvent from UV lacquer can be volatilized after heating, so the bubble won’t be made on the EB.

► It adopts 6pcs of 500w IR lamps to drying base color inks.

► To protect electric controller won’t be splashed by inks, we install it on the IR dying station to control former station running.

►specification of 2.8m IR heating station

Part Eight: UV drying unit

►It is used to curing/drying UV lacquer because UV lacquer should be dried by rays from UV lamp, or it won’t drying naturally or IR lamps.

►It adopts 6pcs of UV lamps to drying UV lacquer, matching 6pcs of transformer+6pcs of capacitor to working together, it also have stronger and light rays, so you can adjust rays according to requirement.

►we adopts 4sets of 0.75kw Low Noise Centrifugal Blower to exhaust heating energy from oven out, so the EB is not easy to burn.

►specification of UV drying station

Part Nine: Haul-off Station

► It is used to pulling wide EB and keep it running with pulling tension, then it won’t easy to falling down and affect printing effect;

► It is driven by servo motor and controlled with one PLC system, so it can keep each station at the same speed.

► In the last station of Haul-off, it has water cooling steel roller, which can cool EB from UV curing machine, before rewinding it, or it is easy bent.

►Specifications of Haul-off Station

Part Ten: rewinding unit

► It is used to rewinding edge band rolls after printing.

► It adopts torque motor to control winding speed.

► torque motor for winding machine is 40N.M.

► the operation table is 600mm wide.

►the center height is 800mm.

(one shaft is 76mm, one shaft is 200mm.)

Part eleven: electric panel

► Except unwinder and rewinder, for other parts are controlled in one complete electric controller;

► All the controllers for servo motors are installed in this big electric controller, then encode in one running PLC system.
