Key features:
- Tailor-Made Hot Air Distribution System: Provides uniform heat distribution, critical for the efficient drying of melamine-impregnated paper.
- High Efficiency: Despite high-speed operation, the system maintains low energy consumption and minimal waste, ensuring cost-effective production.
- Synchronization Unit: Ensures precise coordination of the production process, minimizing defects and enhancing overall quality.
- Extra Half-Bridge Conveyor: Offers additional support and stability during the transfer process, reducing the risk of paper jams or misalignments.
HighLights in Design for 3+5 8-Oven model melamine impregnation lineThick plate frame for steady impregnation unit, with high glossy chromed doctor rollers, long time and easier glue pickup device. Main Features:
Printed paper has a thorough impregnation in glue bath; glue content pick-up is gauged by the gap between two doctor rollers; the roller gap is automatically adjusted by screw motor device.
Scope:
1. Built-in Thick Steel Plate structure, sturdy with no waving. Keeps doctor roller gap without tolerance after adjustment. High precision squeezing roller in chrome‐galvanized, long operating life.
2, S‐Roller tractor unit, Nos 3piece chrome‐galvanized roller, driven by VVVF control, guarantee operating liner speed with unwinder, avoiding paper break.
3. Back‐coating device, Nos. 3 pieces of chrome‐galvanized roller, one for back coating, and other two pieces for angular adjustment when paper is guided through. Nos. 3 piece roller is VVVF controlled liner speed by hand‐knob roller located in RV decelerator.
4, Electrical Sky Roller device consists of one breathing roller and one banana roller. The device is driven by vertical movement at a maximum height of 4.5 meters. this makes paper go in an extra length to give enough time for glue impregnation. breathing roller is driven by VVVF decelerator.
5, Doctor Roller device, No. 2 of Hard-Chrome Galvanized High Glossy roller; one roller located in a fixed position and driven by decelerator through universal joint. Another piece roller can be adjusted with a gap between two rollers. The movable roller at φ290mm, where there is electronics screw, controls roller horizontal movement; the gap precision will be Tan10 x 0.75mm/(3.14 x 24mm) in stepless at a 1.7x10‐4MM degree (0.1micro);
6, Germany Baumer Approaching sensor feedback control, setting digital doctor roller gap and Programming adjustment automatically and indicating directly on color touching screen; after the gap is adjusted, two pairs of air cylinders lock its setting position without loosening.
8, both end of doctors, adopt glue scraper to trim extra glue remains.
9, Smoothing roller device, two piece of chromed SS roller adopted. Counter roller give a reversing leveling of glue; individual VVVF controls smoothing liner speed and keeps the surface glue content in the same and steady Quantity.
10, Resin Bath device, full SS material inter‐layered structure; bath is movable lifting to keep a thorough consumption for glue remains; variety heating can be connected to keep bath glue in a fixed temperature, thus guarantee paper quality without seasons different; temperature control device is built‐in with supplied Impregnation line; glue bath with four universal feet, easier for cleaning and replacement.
