Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0035] Reference Figure 1-14 An automatic edge banding machine according to an embodiment of the present invention is described.

[0036] In one embodiment, such as Figure 1 and Figure 2As shown, an automatic edge banding machine includes a frame 1, a conveyor rail 2 mounted on the frame 1, and a pre-milling assembly, an adhesive application assembly, a cutting assembly, a pressing assembly, a trimming assembly 5, a rough trimming assembly 6, a fine trimming assembly 7, and an edge scraping assembly 8, which are sequentially mounted on the frame 1 along the forward direction of the conveyor rail 2.

[0037] Among them, the pre-milling assembly, glue application assembly, belt feeding and cutting assembly, pressing assembly, end trimming assembly 5, rough trimming assembly 6, fine trimming assembly 7 and edge scraping assembly 8 are all located on the side of the conveying guide rail 2 near the frame 1, and are used to automatically process the sheet metal transported by the conveying guide rail 2 through multiple processes.

[0038] The aforementioned automatic edge banding machine also includes a pressure beam assembly 3, a side support assembly 4, and multiple sets of template components.

[0039] The pressure beam assembly 3 is mounted on the frame 1 and located parallel to and above the conveyor rail 2. It is used to press the plate down onto the conveyor rail 2 to prevent the plate from shifting or derailing.

[0040] The side support assembly 4 includes a side support flow strip 41 and multiple side support brackets 42. The multiple side support brackets 42 are located on the side of the conveying guide rail 2 away from the frame 1 and are evenly arranged along the forward direction of the conveying guide rail 2. The side support flow strip 41 is movably installed on the upper end of the multiple side support brackets 42 and is located parallel to and above the conveying guide rail 2 to assist in sealing the edge of the arc plate, thereby obtaining a more stable edge sealing effect.

[0041] The side guide rail 41 is equipped with rollers on the side facing the frame 1. These rollers support and guide the sheet metal to move smoothly in a specific direction, which can improve processing accuracy and efficiency. In practice, the side guide rail 41 can move up and down and back and forth on the side support frame 42 to accommodate curved sheet metal of different sizes.

[0042] The multiple sets of template components include a trimming template component, a rough trimming template component 60, a fine trimming template component 70, and an edge scraping template component 80. The trimming template component, rough trimming template component 60, fine trimming template component 70, and edge scraping template component 80 are respectively installed on the side of the trimming assembly 5, rough trimming assembly 6, fine trimming assembly 7, and edge scraping assembly 8 near the conveying guide rail 2, and are used to template the plate body on the side of the arc plate to be sealed.

[0043] The aforementioned automatic edge banding machine can be used to band the long side of curved panels, wherein the long side is... Figure 3As shown in Figure A, taking a curved sheet with a long side of only 70mm and a radius of 50mm as an example, the remaining horizontal side length is only 20mm, requiring an additional 10mm to press the sheet firmly. Therefore, the output of the curved sheet is only 10mm. Currently, the smallest narrow workpiece that can be processed by automatic edge banding machines on the market is 200mm*40mm. It is evident that the output of curved sheets is much narrower than that of flat sheets. Here, output refers to the length of sheet material that can be supplied to the edge banding machine for processing. The automatic edge banding machine provided in this embodiment uses a trimming template assembly, a rough trimming template assembly 60, a fine trimming template assembly 70, and a scraping template assembly 80 to achieve template placement, and uses a pressure beam assembly 3 to press the sheet firmly. Simultaneously, the automatic edge banding machine also adds a side-mounting assembly 4 to assist in edge banding of the curved sheet, making the edge banding effect more stable.

[0044] In practice, in order to seal the long side of the curved sheet with a sheet thickness of only 10mm, the overall thickness of the above four template components needs to be relatively thin, for example, less than or equal to the sheet thickness. That is, by making the template components thinner, it is easier to process the curved sheet with a small sheet thickness.

[0045] In this embodiment, as Figure 4 As shown, the feeding end of the conveying guide rail 2 is equipped with a feeding photoelectric sensor 91, a feeding blocking cylinder 92, and a feeding guide bar 93. The feeding guide bar 93 is located on the side of the feeding end. The feeding photoelectric sensor 91 is hung on the side of the pressure plate 32, and the feeding blocking cylinder 92 is hung on the end face of the pressure plate 32 near the feeding end. Both the feeding photoelectric sensor 91 and the feeding blocking cylinder 92 are located above the feeding end.

[0046] The aforementioned automatic edge banding machine also includes a control box 10 installed on one side of the frame 1. The control box 10 is electrically connected to the pre-milling assembly, the gluing assembly, the cutting assembly, the pressing assembly, the trimming assembly 5, the rough trimming assembly 6, the fine trimming assembly 7, and the scraping assembly 8, respectively, and is used to control the automatic operation of each assembly.

[0047] The working process of the above-mentioned automatic edge banding machine is as follows: Before feeding the curved sheet material, adjust the side support assembly 4 to the designated position before the feeding blocking cylinder 92, and then adjust the position of the side support flow strip 41 with the feeding guide strip 93 as a reference. Push the curved sheet material into the conveyor guide rail 2, and start the normal edge banding process after passing through the feeding photoelectric sensor 91. The conventional edge banding process can be: feeding → pre-milling → gluing → tape cutting → pressing → trimming → rough trimming → fine trimming → scraping → polishing → unloading. Among them, other processing function assemblies can be added between the scraping and polishing processes according to customer requirements.

[0048] The automatic edge banding machine provided in this embodiment can achieve edge banding through the end-trimming template assembly, the rough trimming template assembly 60, the fine trimming template assembly 70, and the scraping template assembly 80, and press the board through the pressure beam assembly 3; at the same time, the automatic edge banding machine is also equipped with a side-mounting assembly 4 to assist in edge banding of curved boards, which can perform rapid edge banding of curved boards in a production line, improving the smoothness, stability and processing efficiency of the curved edge banding process.

[0049] In this embodiment, as Figure 5 As shown, the upper end of the side support frame 42 is provided with a guide rail 43 perpendicular to the forward direction of the conveying guide rail 2. A synchronous belt mechanism is provided on one side of the guide rail 43. A slide 44 is provided on the guide rail 43. One side of the slide 44 is connected to the synchronous belt 45 of the synchronous belt mechanism. The other side of the slide 44 is provided with a cylinder 441 and a guide shaft 443 that are parallel to each other. The movable rod of the cylinder 441 is connected upward to the bottom surface of the fixed block 46 below the side flow strip 41 through a floating joint 442. The top end of the guide shaft 443 is connected to the bottom surface of the fixed block 46. The top surface of the fixed block 46 is fixedly connected to the bottom surface of the side flow strip 41.

[0050] The slide block 44 consists of a slider and a mounting base fixed to the top of the slider. The slider is slidably mounted on the guide rail 43 to move back and forth against the flow bar 41. One side of the mounting base is bent downwards onto the timing belt 45, and a clamping part is provided at the end. This clamping part clamps the timing belt 45 in the middle to fix it to the timing belt 45, so that the slide block 44 can be driven by the timing belt 45 to move back and forth on the guide rail 43. The other side of the mounting base is provided with two through holes for mounting the cylinder 441 and the guide shaft 443, and the flow bar can be moved up and down through the cylinder 441 and the guide shaft 443. The floating joint 442 acts as a buffer between the cylinder 441 and the fixed block 46, and plays a role in protecting the cylinder 441 and the fixed block 46.

[0051] In this embodiment, the synchronous belt mechanism includes a synchronous belt 45, a driving synchronous pulley 451, and a driven synchronous pulley 452. The driving synchronous pulley 451 and the driven synchronous pulley 452 are respectively located at both ends of the synchronous belt 45, which drives the synchronous belt 45 to move back and forth. A synchronous belt drive motor 47 is provided on the side support frame 42 in the middle of the multiple side support frames 42. The shaft of the synchronous belt drive motor 47 is connected to the shaft of the driving synchronous pulley 451 of each synchronous belt mechanism through a coupling.

[0052] The side-mounted assembly 4 is equipped with a synchronous belt drive motor 47, which drives multiple synchronous belts 45 to rotate, maintaining the synchronicity of each synchronous belt mechanism, thereby ensuring that the side-mounted flow bar 41 is always parallel to the conveyor rail 2.

[0053] In specific implementation, such as Figure 1As shown, the side support assembly 4 may also include a protective cover 48 arranged around a plurality of side support brackets 42 for protecting the equipment and preventing external interference.

[0054] The automatic edge banding machine in the above embodiment has a newly added side support assembly 4 structure, which helps to assist in edge banding of curved panels, making the edge banding effect more stable. In addition, the position of the side support flow strip 41 is adjustable in front and behind, and in height, which can be conveniently applied to curved panels of different sizes, thus improving the adaptability of the automatic edge banding machine.

[0055] In this embodiment, as Figure 6 and Figure 7 As shown, the beam pressing assembly 3 includes a beam pressing mechanism and multiple beam pressing lifting mechanisms 31. The multiple beam pressing lifting mechanisms 31 are mounted on the frame 1 and are evenly arranged along the forward direction of the conveying guide rail 2.

[0056] The beam pressing mechanism includes a pressure plate 32 and a beam pressing roller 33 located at the bottom of the pressure plate 32. The pressure plate 32 is connected to the lower end of multiple beam pressing lifting mechanisms 31 through a beam pressing pad 34, and the pressure plate 32 is located above the conveying guide rail 2 in parallel.

[0057] The two sides of the pressure beam pad block 34 are connected to the pressure beam lifting mechanism 31 and the pressure plate 32 via A-type flat keys. The width of the pressure plate 32 and the pressure beam roller 33 can be set to less than or equal to 10mm to accommodate arc-shaped plates with small output.

[0058] In practice, since the width of the pressable surface of the arc-shaped sheet is only 10mm and the sheet output is only 10mm, the pressure beam must be very thin to adapt to the edge banding process of the arc-shaped sheet. Therefore, the above-mentioned automatic edge banding machine adopts an improved thin pressure beam, which can achieve the pressing of the sheet body on the side to be edge banded of the arc-shaped sheet.

[0059] In this embodiment, as Figure 8 As shown, the end-cutting assembly 5 includes an end-cutting blade, an end-cutting blade, an end-cutting motor for driving the end-cutting blade to rotate, and an end-cutting motor for driving the end-cutting blade to rotate.

[0060] The end-cutting template assembly includes an end-cutting plate 501 and an end-cutting plate 502. The end-cutting plate 501 is a strip plate located on the side of the end-cutting cutter near the conveyor rail 2. The side of the strip plate is provided with a mounting part, which is mounted on the mounting base of the end-cutting motor.

[0061] The tail-end support plate 502 is a square plate located on the side of the tail-end cutter near the conveyor rail 2. The upper part of the square plate is mounted on the mounting base of the tail-end motor, and the lower two ends are equipped with tail-end pressure rollers. The square plate has a hole in the middle and rounded corners.

[0062] In practice, the width of the flushing roller can be set to less than or equal to 10mm to accommodate curved plates with small output. In practice, in order to seal the long side of the curved plate with an output of only 10mm, the traditional flushing assembly 5 template component is directly eliminated and replaced with the flushing template component in this embodiment.

[0063] In this embodiment, as Figure 9 and Figure 10 As shown, the roughing assembly 6 includes a roughing milling cutter and a roughing motor that drives the roughing milling cutter.

[0064] The roughing template assembly 60 includes a roughing fixing seat 601, a roughing adjusting plate 602, and a roughing roller support plate 603. The rear end of the roughing fixing seat 601 is mounted on the mounting seat of the roughing motor. The rear end of the roughing adjusting plate 602 is fixedly connected to the lower front end of the roughing fixing seat 601, and the front end of the roughing adjusting plate 602 is provided with a roughing adjustment screw.

[0065] The roughing roller support plate 603 is a U-shaped plate with rollers at both ends and the bottom of the U-shape is adjustablely connected to the front front of the roughing fixing seat 601. The bottom end face of the roughing roller support plate 603 abuts against the top end of the roughing adjustment screw. The roughing roller support plate 603 is located on the side of the roughing milling cutter near the conveying guide rail 2, and the roughing milling cutter part is located in the U-shaped opening of the roughing roller support plate 603.

[0066] The front end of the roughing fixing base 601 has two elongated through holes along the vertical direction. The back of the roughing roller support plate 603 is adjustablely connected to the two elongated through holes by two screws. Since the roughing adjustment screw is pressed against the bottom surface of the roughing roller support plate 603, the roughing roller support plate 603 can be moved up and down along the direction of the elongated through holes by adjusting the roughing adjustment screw, which can adjust the position of the roughing template assembly 60. This can adapt to arc plates of different thicknesses and improve the applicability of the above-mentioned automatic edge banding machine.

[0067] In this embodiment, as Figure 11 and Figure 12 As shown, the finishing assembly 7 includes a finishing milling cutter and a finishing motor that drives the finishing milling cutter. The finishing template assembly 70 includes a finishing mounting base 701, a finishing adjustment plate 702, and a finishing roller support plate 703. The rear end of the finishing mounting base 701 is mounted on the mounting base plate of the finishing motor. The rear end of the finishing adjustment plate 702 is fixedly connected to the lower front end of the finishing mounting base 701, and the front end of the finishing adjustment plate 702 is provided with a finishing adjustment screw.

[0068] The finishing roller support plate 703 is a U-shaped plate with rollers at both ends and the bottom of the U-shape is adjustablely connected to the front front of the finishing fixing seat 701. The bottom end face of the finishing roller support plate 703 abuts against the top end of the finishing adjustment screw. The finishing roller support plate 703 is located on the side of the finishing milling cutter near the conveying guide rail 2, and the finishing milling cutter part is located in the U-shaped opening of the finishing roller support plate 703.

[0069] The front end of the finishing fixing base 701 has two elongated through holes along the vertical direction. The back of the finishing roller support plate 703 is adjustablely connected to the two elongated through holes by two screws. Since the finishing adjustment screw is pressed against the bottom surface of the finishing roller support plate 703, the finishing roller support plate 703 can be moved up and down along the direction of the elongated through holes by adjusting the finishing adjustment screw, which can adjust the position of the finishing template assembly 70. This can adapt to arc plates of different thicknesses and improve the applicability of the above-mentioned automatic edge banding machine.

[0070] In practice, based on the difference in structure between the rough repair assembly 6 and the fine repair assembly 7, the length of the U-shaped side of the fine repair roller support plate 703 is less than the length of the U-shaped side of the rough repair roller support plate 603.

[0071] In this embodiment, as Figure 13 and Figure 14 As shown, the scraping assembly 8 includes a scraping knife, and the scraping template assembly 80 includes a scraping fixing seat 801, a scraping adjusting plate 802, and a scraping roller support plate 803. The rear end of the scraping fixing seat 801 is mounted on the side of the mounting plate of the scraping knife; the rear part of the scraping adjusting plate 802 is fixedly connected to the bottom surface of the mounting plate of the scraping knife, and the front part of the scraping adjusting plate 802 is provided with a scraping adjustment screw.

[0072] The scraping roller support plate 803 is a U-shaped plate with rollers at both ends and the back of one side of the U-shape is adjustablely connected to the front front of the scraping fixing seat 801. The bottom end of the scraping roller support plate 803 abuts against the top end of the scraping adjustment screw. The scraping roller support plate 803 is located on the side of the scraping knife close to the conveying guide rail 2, and the scraping knife part is located in the U-shaped opening of the scraping roller support plate 803.

[0073] The scraping edge fixing seat 801 has two elongated through holes on its front end along the vertical direction. The back of the scraping edge roller support plate 803 is adjustablely connected to the two elongated through holes by two screws. Since the scraping edge adjusting screw is pressed against the bottom end surface of the scraping edge roller support plate 803, the scraping edge roller support plate 803 can be moved up and down along the direction of the elongated through holes by adjusting the scraping edge adjusting screw, which can adjust the position of the scraping edge template assembly 80. This is beneficial for adapting to boards of different thicknesses and improves the applicability of the above-mentioned automatic edge banding machine.

[0074] In practice, based on the different structures of the roughing assembly 6 and the scraping assembly 8, the scraping roller support plate 803 not only has a shorter U-shaped side length than the roughing roller support plate 603, but its U-shaped opening width is also smaller than that of the roughing roller support plate 603.

[0075] In specific implementation, the width of the rollers used in each roller support plate in the above embodiments can be set to less than or equal to 10mm to adapt to arc-shaped plates with a small output.

[0076] The automatic edge banding machine provided in the above embodiments, in order to adapt to the edge banding of curved plates, eliminates the traditional upper and lower two-plane template components on the main structure of the roughing assembly 6, fineing assembly 7, and scraping assembly 8, leaving only the side wheel template component that does not affect the installation of the curved plate, and improves it to obtain the roughing template component 60, fineing template component 70 and scraping template component 80 in the above embodiments, which can realize the automatic edge banding processing of the long side of the curved plate.

[0077] Other configurations and operations of the automatic edge banding machine according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
