Common Methods to Enhance the Edge Sealing Effect of Edge Banding Machine

With the continuous development of society, edge banding machines are more and more widely used in our daily lives. Pre-milling, gluing, flushing, rough trimming, finishing, scraping, polishing, slotting, etc. are its main functions. The edge banding machine is mainly used for the production of panel furniture and wooden doors. But how can we make the edge banding machine better? The following are several common methods

1. The indoor temperature should not be too low during processing, generally, it should be above 15°C, especially when the edge banding is thick, the flexibility will be insufficient, to ensure the normal operation of the preheating device, if there is no preheating device, the hairdryer can also be used Heating and other methods soften the edge banding. This method is especially suitable for curved edge banding. There must be no demeanor in the processing workshop. The quality of the edge banding affects the edge banding effect. The products sealed by the good quality banding band are tightly sealed, and the products sealed by the poor quality banding band have a large gap at the edge band, and there is a clear black line. When the machine is trimming, the backer is easy to scratch marks on the surface. The thickness of the thick edge banding should be slightly concave than the two sides when viewed from the cross-section. The product sealed by this edge banding is tighter and the effect is better.

2. Because the sealing speed is very fast, the adhesive under low pressure to have a good dispersion and the permeability of the substrate, to have a good initial viscosity, in a short time under the pressure should be instant bonding, bonding firm. When using, pay attention to ensure that the temperature of the hot melt adhesive is within the normal temperature range, long time too high temperature will make the adhesive; Hot melt glue cannot reach good fluidity at low temperature, so it is necessary to master the data provided by the supplier when using it.

3. The amount of hot melt adhesive should be based on the slightly extruded glue on the outside of the glued part. If it is too large, there is a black line at the edge of the edge, which affects the appearance; too small, the glue strength is not enough. In order to check whether the adhesive film is continuous, you can use transparent hard PVC tape to test; you can also use ordinary edge banding, tear off the edge banding tape when the adhesive is not cooled to test.

4. For the manufacturers of edge banding machines without the front milling cutter device, the cutting quality of the semi-finished products to be edge banded also affects the edge banding effect. Generally, in order to prevent the product from bursting, the high frequency joining machine manufacturer will use a scoring saw (commonly known as a small saw blade) when cutting. The best effect after cutting should be thavt small saw blade marks can be seen at the cross-section but can not be felt by touch. The edge of the small saw blade is too deep when the edge is sealed, and a black line can be seen at the edge of the edge, and even the gap can be seen. It is too shallow and easy to burst.

5. If the selection of thick edge sealing, sealing machine press roller tension should be adjusted to the best position, the most common problem is too tight pressure. Because the sealing sideband is slightly longer than the workpiece, when the pressing roller presses the growing part of the sealing sideband, the sealing sideband will be given a force perpendicular to the feeding direction. At this time, due to the incomplete curing of the adhesive, the gluing strength is not high, and the tail is easy to loosen and not stick well.
