Introduction of each unit of linear edge banding machine(2)

In the manufacturing process of customized furniture, the edge sealing is one of the most important links. Common edge banding equipment mainly include: portable hand-held edge banding machine, manual edge banding machine, CNC machining center and linear edge banding machine.

Among them, the linear edge banding machine, which is used most frequently and has the highest production efficiency, has become one of the necessary equipment for customized furniture manufacturers. So what are the main units of a linear edge banding machine? What kind of influence will each unit have on the final finished sheet?

Head to head cutting

Generally, the length of a roll of edge banding strip is 100 meters or 150 meters. After the edge banding strip is fed, the edge banding strip is generally 10 mm more than the plate. The function of end trimming is to cut off the part of the edge banding strip beyond the plate, so as to prepare for the subsequent edge banding.

Roughing unit

Generally, the width of the edge banding strip is about 5 mm wider than that of the plate. For example, for the most common 18 mm plate on the market, the matching edge banding is 23 mm. In this case, the upper and lower ends need to be repaired about 2.5 mm. For cutting tools, if the cutting amount is too large, it will have a greater impact on the life of the tool and the cutting quality. Therefore, before finishing, adding roughing unit can effectively improve the quality of trimming and reduce the loss of finishing knife.

Refinement unit

Finishing is to further process the plate with good edge banding on the basis of rough trimming to obtain the ideal trimming radian. Generally, there are two kinds of finishing radians: arc and 45 ° oblique cutting. The radian of the arc can be selected according to the thickness of the edge banding strip. 45 ° oblique cutting can be divided into only cutting edge strips, or cutting edge strips and surface materials at the same time.

Tracking unit

The general process of plate edge sealing is to seal two short sides (called one or two sides), and then seal two long sides (called three or four sides). Tracking is turned on when sealing three or four sides. Its function is to repair the intersection line matching the refined radian at the junction of one or two sides and three or four sides.

Scraper unit

After finishing, linear knife marks often appear at the arc of the edge banding strip. The function of the scraper is to eliminate these marks and make the trimming more smooth and beautiful.

Flat blade unit

In order not to touch the surface of the plate when trimming, the finishing knife and scraper are usually set slightly higher than the surface of the plate when working. If you touch with your hand, you can find that after finishing, the edge banding strip will be slightly higher than the board surface, so the function of the blade is reflected. The blade can level the slightly higher part of the plate surface of the edge banding strip after finishing. If the plate with protective film is sealed, the best blade state is to just remove the protective film, so that when the protective film is finally removed, the edge sealing strip will not be significantly higher than the plate.

Polishing unit

The common edge banding materials are PVC, ABS, PMMA and PP. The surface of these materials will lose luster after cutting. Therefore, the function of the polishing unit is to restore the luster of the surface of the edge banding strip at the trimming position. For high gloss products, the polishing unit determines the overall unity between the edge banding strip and the plate
