How To Control The Quality Of The Edge Banding?

(1) If thick edge banding is used to band the edge, the pressing roller of the edge banding machine should be adjusted to the best position. The most common problem is that the pressure is too tight. Since the edge band is slightly longer than the work piece, when the pressing roll presses the length of the edge band, the edge band is provided with a force perpendicular to the feeding direction. At this time, since the glue is not completely cured, the bonding strength is not high. The tail is easy to loosen and not sticky.

(2) The indoor temperature should not be too low during processing, generally should be above 15 °C, especially when the edge band is thick, the flexibility will be insufficient, to ensure the normal operation of the preheating device. If there is no preheating device, it can also be used. The edge band is softened by blowing or the like, and the method is particularly suitable for curved edge banding. There must be no wind across the workshop.

The quality of the edge banding roll affects the edge banding effect. The banded edge of the banded product with good quality is tightly banded, and the gap of the product sealed by banding tape with poor quality is large, and there is a clear black line. When the machine is trimming, it is easy to scrape off the surface on the surface. From the cross-section of the thick edge banding, the middle of the gluing surface should be slightly concave than the two sides. The edge banding of the sealing band is tighter and the effect is good.

(3) The moisture content of solid wood edge-banding materials should not be too high. It should be stored in a cool and dry room. The substrate requires no dust, and the optimum moisture content is 8-10%.

(4) Due to the fast edge-banding speed, the adhesive should have good dispersion and permeability to the substrate under low pressure. It should have good initial tack and should be glued instantly under a short time pressure. The knot is firm. When using, care should be taken to ensure that the temperature of the hot melt adhesive is within the normal temperature range. If the temperature is too high for a long time, the glue will be separated; if the hot melt adhesive does not reach good fluidity at low temperature, it must be provided by the supplier data when using it.

(5) The amount of hot melt adhesive should be such that the glue is slightly extruded outside the glued part, too large, there is a black line at the edge of the seal, which affects the appearance; too small, the glue strength is not enough.

In order to check whether the film is continuous, it can be tested with a transparent hard PVC. it can also be sealed with a common edge banding. When the silicone is not cooled, the edge band is torn off for inspection.

(6) For the manufacturing of the edge banding machine without the front pre-milling diamond cutter device, the cutting quality of the semi-finished product to be sealed also affects the edge banding effect. In order to prevent the product from being blasted. The general manufacturer will use a nicker saw (commonly known as a small saw blade or grooving blades). The best effect after cutting should be that the saw blade can be seen in the section but it is not felt. When the small saw blade marks are too deep, the seal is not strong, and a black line can be seen at the edge of the seal to even see the gap, which is too shallow and easy to explode.

What should you pay attention to when the edge bander is working safely:

1. The workplace should be equipped with complete and reliable fire-fighting equipment. Smoking and open flames are strictly prohibited in the workplace, and flammable products such as oil and cotton yarn are not allowed to be stored;

2. The wood to be processed and processed wood in the workplace should be piled up neatly to ensure smooth roads;

3. The machinery should be kept clean, the safety protection device is complete and reliable, the joints of the various parts are fastened, and no debris can be placed on the workbench;

4. Before the operation, the frame and the fixture should be adjusted. The table should be stable, the drill should be vertical, and the chisel should be stuck in the center of the chisel and perpendicular to the machined hole;

5. When you are eye-catching, you must use the clamper. Do not directly support the material by hand. If it is thrifty, it must be pressed slowly. Do not use excessive force. Do not wear gloves.

6. In the operation, if the chiseling is blocked by raft or wood slag or the high temperature causes the wood to smoke, the handle should be lifted immediately, and the drilled wood residue should not be directly cleaned by hand;

7. When replacing the core, stop the power supply first, and then put the board on the platform before proceeding;

8. After the operation, cut off the power supply, lock the brake box, wipe and lubricate, and remove wood chips and shavings.
