The above-mentioned glue coating and weaving part 2, the pressing and cutting part 3, the rough trimming part 4, the fine trimming part 5, the scraping part 6, the flexible flat scraping part 7, and the polishing part 8 can be installed on the edge banding base 1 from right (front) to left (back), wherein the glue coating and weaving part 2 and the pressing and cutting part 3 can be respectively provided with two, and the two are cross-installed, and the workpiece can be edge banded by the above-mentioned structural components. Processing, wherein, after passing through the finishing part 5, the workpiece needs to be scraped by the scraping part 6.

The above-mentioned floating cylinder body 73 can push the transverse bottom plate 71 to move toward the workpiece during operation, and make the floating knife group 72 contact the edge banding strip of the workpiece, so as to perform flat scraping repairs on the uneven positions of the upper and lower surfaces of the edge banding strip.

[0041] Among them, when the flexible flat scraper 7 is not used in the edge sealing device 100, air pressure is supplied through the air inlet nozzle 731, and then the floating cylinder body 73 drives the horizontal seat plate 71 and the floating knife group 72 to move upward, so that the workpiece does not contact the flexible flat scraper 7 when passing through the workstation, thereby increasing the process processing diversity of the edge sealing device 100.

[0042] Exemplary floating knife set

[0043] like Figure 2-Figure 3 As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned floating knife group 72, wherein the floating knife group 72 of this structure includes a blowing seat 721, a floating connecting block 722, and a mold-supporting floating knife head 723, wherein the blowing seat 721 is installed at the bottom of the horizontal seat plate 71, the floating connecting block 722 is installed at the bottom of the blowing seat 721, and then the mold-supporting floating knife head 723 is installed at the bottom of the floating connecting block 722, and the front side of the mold-supporting floating knife head 723 is obliquely provided with a repair blade 724, so after the mold-supporting floating knife head 723 contacts the workpiece, the repair blade 724 scrapes and repairs the uneven positions of the upper and lower surfaces of the edge banding strip, making the surface of the workpiece smoother. At the same time, the blowing seat 721 is connected to an external air source, thereby blowing away the wood chips generated by the workpiece repair from the repair blade 724.

[0044] Furthermore, an auxiliary blade 725 is installed obliquely on the front side of the above-mentioned floating cutter head 723.

[0046] Furthermore, an air inlet side hole is opened on one side of the above-mentioned blowing seat 721, and an air blowing hole is opened on the front side. The two are connected inside the blowing seat 721, and an air blowing nozzle body 730 is installed on the air blowing hole.

[0066] Furthermore, an air inlet 731 is installed on the floating cylinder body 73, and high-pressure gas is supplied through the air inlet 731, which in turn pushes the floating piston rod 751 to move toward the first spring stop 743, thereby driving the transverse seat plate 71 and the floating tool group 72 to leave the workpiece.

[0067] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0068] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0069] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
