The most critical position or the essential part of the
automatic edge banding machine is the gluing of the board, which should be uniform and continuous to ensure full adhesion with the edge strip. So how should the glue be applied, and how to it adjusts the amount of glue?
Generally, there will be an iron handle on the plastic box of the automatic edge banding machine, which can be adjusted by moving it back and forth.
1. The glue in the glue pot must be kept below 1cm from the pot mouth but not lower than the two reinforcing ribs in the pot.
2. The amount of glue applied should be adjusted by adjusting the handle according to the workpieces size, width, and thickness.
3. The in and out of the glue pot of the automatic edge banding machine can be adjusted by the adjusting screw behind the glue pot. First, loosen the lock nut, then use the flat change knife to rotate the adjusting screw clockwise, and the glue pot will move back. Move the pot forward and tighten the nut after adjustment.
4. The size of the elasticity of the glue pot can be adjusted by the nut behind the lock spring of the glue pot. Rotate clockwise to increase the elasticity. Otherwise, the elasticity decreases.
5. The glue pot of the automatic edge banding machine is too far forward, and it is easy to cause the workpiece to hit the pot and damage the workpiece and equipment; the front end has no glue or glue, but the bonding is not good; the glue pot is too far back, and it is easy to appear that the whole workpiece has less glue or even no glue—adhesive and poor bonding, resulting in repairs. If the elasticity is too large, it is easy to cause the phenomenon that the front end has glue, but the bonding is not good, and the back end is expected, or the front end of the workpiece is chamfered. Sometimes the sealed workpiece will have honeycomb eyes.
6. If the elasticity is too small, it is easy to have too little glue on the workpiece or even no glue. The glue return hole should be kept open at all times. Otherwise, the lower part of the workpiece will be dirty and affect the quality. At the same time, the glue will also be attached to the conveyor belt and the travel switch, causing the travel switch to malfunction and damage the workpiece and equipment.
7. The outside of the glue pot is too dirty through the automatic edge banding machine, which will affect the appearance in the first place. If the upper part of the glue pot is too dirty and dirt is formed due to long-term high temperatures, the glue pot will not return when sealing the workpiece, affecting the quality of the sealing edge.
