Why does the edge banding machine have black lines?

The quality and effect of the edge banding of the automatic edge banding machine are the key factors to determine the quality of the product. However, some customers found that black lines tend to appear at the joints between the edge banding strip and the board during use. Where does this black line come from? Woolen cloth?

How to solve the black line in the edge banding machine?

1. The edge banding functions of the furniture edge banding machine generally include preheating, pre-milling, gluing and pressing, front and rear trimming, rough trimming, fine trimming, scraping, slotting, and polishing. Most customers will remove the pre-milling and grooving functions, so that there will be stricter requirements for the cutting and blanking of the previous process, and the cutting board will be at a 90-degree angle, and there will be no concave-convex board surface.

2. When using a sliding table saw to cut the board, ensure that the scribing saw and the main saw blade are turned on at the same time, and the angle of the main saw blade is adjusted vertically to 90 degrees. The scribing work of the scribing saw blade is to ensure that the edge of the board is Not collapsing, it plays a vital role in the edge banding of the board.

3. Analyze the amount of glue applied to the glue tank of the CNC edge banding machine, reduce the amount of glue applied, and prevent the phenomenon of glue overflow. Usually, the conventional method is to adjust the amount of glue applied to meet all the above edge sealing requirements.

4. After checking the above points, the rest is the key work of equipment installation and technical debugging, which is the key technology for evaluating an edge banding machine manufacturer.

In the above content, we have analyzed the reasons for the black line when the edge banding machine is working. From this, we understand that the quality of the equipment is very important, and the processing effect of the equipment determines the quality of the edge banding of the plate, so everyone should pay more attention when using it. These points are to prevent equipment problems and affect normal use.
