[0002] Customized products have become the first choice for most people in the furniture industry. In the edge banding process, with the continuous rise in customization and personalization demands, the quality requirements of products are getting higher and higher. Edge banding machines can realize multi-functional integrated operations such as pre-milling, gluing, trimming, rough trimming, fine trimming, scraping, and polishing, which significantly improves processing efficiency. They are especially suitable for the mass production needs of large and medium-sized furniture factories. Through precision guide rails and automatic tracking systems, edge banding machines can ensure that the edge banding strip is tightly attached to the board, achieving a flat and smooth processing effect and avoiding burrs or unevenness.

[0003] However, traditional edge banding techniques have the following drawbacks:

[0004] Traditional edge banding processes use rounded corners of R1.5, R2, or 45 degrees. Most edge banding machines are equipped with only one blade. With the diversification of edge banding processes, one blade is difficult to meet the needs of various edge banding processes. Utility Model Content

[0030] The wire feeding system 7 is equipped with a lower wire suction dust cover 71 and an upper wire suction dust cover 72. One end of the lower wire suction dust cover 71 and one end of the upper wire suction dust cover 72 are fixedly connected to the multi-functional fine trimming frame assembly 1.

[0031] In this embodiment, the multi-functional precision trimming frame assembly 1, servo horizontal template assembly 2, servo vertical template assembly 3, servo tool changer motor assembly 4, servo motion adjustment assembly 5, and multi-functional drive assembly 6 are fixed to the edge banding machine. After the servo multi-functional precision trimming unit and tracking are completed, and after the normal completion of edge banding glue application, pressing, end trimming, rough trimming, precision trimming, tracking, and other related processes, the multi-functional precision trimming frame assembly 1 and the upper and lower sliding base plate 102 can be adjusted by adjusting the lower stroke screw to allow the vertical template 38 to contact the board surface. For example, when prioritizing the adjustment of the R1.5 arc, the servo horizontal guide module 2 is used to adjust the first servo motor 21 to drive the first ball screw 27, so that the horizontal guide 26 moves forward and backward, and the R1.5 cutting edge in the multiple sets of cutting blades 47 forms a positional relationship. Similarly, the servo vertical guide module 3 is used to adjust the second servo motor 31 to drive the second ball screw 36 to drive the vertical guide 38, so that the cutting tool and the vertical guide 38 in the vertical direction form a positional relationship, and the R1.5 cutting edge in the multiple sets of cutting blades 47 forms a positional relationship. Then, the third servo motor 41 drives the third ball screw 43 to control the forward and backward movement of the entire mechanism. When the horizontal template 26 contacts the plate, the third servo motor 41 moves forward 0.5mm, meaning our movement is 0.5mm. Similarly, in the vertical direction, by adjusting the travel screw, the vertical template 38 can be made to contact the plate surface, and then adjusted upward 0.5mm to ensure that the plate we pass through always contacts the template. The same principle applies to the upper scraping edge. When it is found that the arc angle of the edge banding is not the effect we need, we adjust the servo motors of the horizontal template 26 and the vertical template 38 according to the actual situation to compensate the servo motors according to our edge banding effect until we achieve the desired effect. The position signal of the servo motor is recorded. Finally, the adjustment method for other arc or chamfer processes is the same. The parameters of the three edge banding processes are recorded respectively. After saving the parameters, one-click switching is achieved through the software, realizing manual adjustment-free operation and solving the problem of one unit meeting the needs of different processes.
