Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically, to a servo precision finishing device for edge banding machine. Background Technology

[0002] Edge banding machines, as highly specialized pieces of machinery, are meticulously designed to meet the edge banding needs of wood panels. Their applications are extremely wide-ranging, playing a crucial role not only in the furniture manufacturing industry but also in cabinet production, woodworking, and many other related industries, becoming an indispensable processing equipment.

[0003] After the board processing is completed, its surface is not ideally uniform and flat; rather, variations in thickness are inevitable. Specifically, some areas of the board may be relatively thin, while other areas may be thicker. This unevenness in thickness places higher demands on subsequent edge banding treatment.

[0004] If a fixed-size trimming method is used to uniformly process the edge banding, it will be difficult to accurately adapt to the actual shape and size of the board ends, resulting in an imperfect fit between the edge banding and the board. Specifically, the edge banding may be under-trimmed, exceeding the thickness of the board and forming a protruding edge, affecting aesthetics and practicality; or it may be over-trimmed, cutting to the edge of the board, even causing damage or defects, seriously affecting product quality and lifespan. Therefore, to ensure a precise match between the edge banding and the board ends, real-time fine-tuning is necessary based on the actual conditions of the board. This fine-tuning requires the edge banding machine to have high flexibility and precision, capable of real-time adjustments based on differences in board thickness to ensure that the edge banding fits tightly to the board ends, achieving the ideal edge banding effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0030] like Figures 1-8 As shown, a servo finishing device for a board edge banding machine includes a support frame 1. An upper edge trimming mechanism and a lower lifting mechanism are slidably fitted on the support frame along the vertical direction. A driving mechanism is provided between the upper edge trimming mechanism and the lower lifting mechanism. The driving mechanism can drive the upper edge trimming mechanism away from or closer to the lower lifting mechanism.

[0031] In at least one embodiment, the support frame includes a base 11 and a top plate 13. Two vertical guide rods 14 are provided between the base and the top plate. A lower main slide block 21 and an upper main slide block 22 are slidably fitted on the vertical guide rods. The upper main slide block is directly above the lower main slide block. A lower auxiliary slide block 31 is slidably fitted on the lower main slide block. A lower lifting mechanism is fixedly connected to the lower auxiliary slide block. An upper auxiliary slide block 32 is slidably fitted on the upper main slide block. An upper trimming mechanism is fixedly connected to the upper auxiliary slide block. This design ensures that the upper trimming mechanism and the lower lifting mechanism can move stably and smoothly in the vertical direction, improving the processing accuracy and stability.

[0032] In a more detailed design, an upper horizontal rod 321 is fixedly connected to the upper auxiliary slider. Two upper horizontal rods pass through the upper main slide and connect to the linkage plate 47. A wire encoder 46 is mounted on the upper main slide, and a support base 48 is mounted on the linkage plate. The wire of the wire encoder is connected to the support base. A through hole 471 is formed at the lower end of the linkage plate. The application of the wire encoder enables precise control of the position of the upper trimming mechanism, improving the automation level of the processing.

[0033] The plan should be refined, such as Figure 7 and Figure 8 As shown, the lower main slide has the same structure as the upper main slide, including a main central connecting plate 211, a main left connecting plate 212 and a main right connecting plate 213, and through holes 214 on the main left and right connecting plates. The lower auxiliary slide has the same structure as the upper auxiliary slide, including a secondary central connecting plate 311, a secondary left connecting plate 312 and a secondary right connecting plate 313, and mounting holes 314 on the secondary left and right connecting plates.

[0034] The solution is detailed as follows: the lower auxiliary slide block is equipped with a second motor 51, a second ball screw 52, ​​a second nut mounting seat 53, and a second nut. The second nut is installed in the second nut mounting seat and cooperates with the second ball screw. The second nut mounting seat is fixedly connected to the lower main slide block. The second motor is fixedly connected to the lower auxiliary slide block, and the output shaft of the second motor is connected to the second ball screw. The rotation of the second motor can drive the lower auxiliary slide block to move along the lower main slide block. A lower horizontal bar is fixedly connected to the lower auxiliary slide block. The two lower horizontal bars pass through the lower main slide block and are connected to the right connecting plate 54. A linkage bolt 55 is provided on the right connecting plate. The linkage bolt is located in the through hole 471. A limiting ring is provided at the end of the bolt. A third flexible spring 56 is provided between the limiting ring and the linkage plate. The third flexible spring can drive the linkage plate to move closer to the right connecting plate.

[0035] Furthermore, a first flexible spring 6 is provided between the base and the lower main slide, and the first flexible spring drives the lower main slide to move away from the base.

[0036] Furthermore, such as Figure 4 As shown, a rear plate 12 is also provided between the base and the top plate. A precision lower limit block 71 is installed on the rear plate, and a limit bolt 72 is threadedly connected to the bottom of the precision lower limit block. The combined design of the precision lower limit block and the limit bolt ensures the range of motion of the lower main slide.

[0037] In a more detailed design, the first flexible spring causes the top of the lower main slide to abut against the limiting bolt. This design ensures that the lower main slide can stably remain in the preset position when no external force is applied, thus improving the reliability of the equipment.

[0038] Furthermore, the drive mechanism includes a first motor 23, a first ball screw 24, a first nut mounting seat 25, and a first nut. The first nut is installed in the first nut mounting seat and cooperates with the first ball screw. The first nut mounting seat is fixedly connected to the upper main slide, and the first motor is fixedly connected to the lower main slide. The output shaft of the first motor is connected to the first ball screw. The rotation of the first motor can drive the lower main slide and the upper main slide to move closer or further apart. The distance between the upper trimming structure and the lower lifting structure can be adjusted by the drive mechanism. This drive mechanism design enables precise adjustment of the distance between the upper trimming mechanism and the lower lifting mechanism, improving the adaptability and flexibility of processing.

[0039] In at least one embodiment, the upper trimming mechanism includes a trimming fixing plate 45, a trimming motor 42 is fixedly connected to the trimming fixing plate, the output shaft of the trimming motor is connected to a trimming cutter head 43, and a contour wheel position adjustment mechanism is provided at the bottom of the trimming fixing plate.

[0040] Furthermore, the contour wheel position adjustment mechanism includes a lower mounting plate 86. A first slide rail 87 is fixedly connected to the lower mounting plate by a first bolt 811, a second bolt 812, and a third bolt 813. A first slider 82 is slidably fitted on the first slide rail. The top of the first slider is fixedly connected to the lower plate 81. The lower plate is connected to a finishing fixing plate. A left connecting plate 85 is provided on the left side of the lower mounting plate. An end plate 84 is provided on the left connecting plate. An upper contour wheel 44 is rotatably connected to the end plate. A fixing bolt 88 and a locking bolt 810 are provided on each side of the lower mounting plate. An auxiliary plate 83 is formed at the bottom rear side of the lower plate. A tension bolt 89 is provided on each side of the auxiliary plate. A fastening bolt 90 is threadedly connected to the middle of the auxiliary plate. The end of the fastening bolt abuts against the right end of the first slide rail. A second flexible spring 814 is provided between the fixing bolt and the tension bolt. The contour wheel position adjustment mechanism allows for adjustment of the upper contour wheel's front-to-back position and left-to-right rotation, ensuring its coaxial alignment with the finishing cutter head. Front-to-back adjustment is achieved through a second flexible spring and a fastening bolt. This contour wheel position adjustment mechanism design enables precise position adjustment of the upper contour wheel.

[0041] Furthermore, such as Figure 6As shown, the lower mounting plate has a left positioning hole, a central elongated hole 861, and a right elongated hole 862. The first bolt passes through the left positioning hole and is threaded into the threaded hole at the bottom of the first slide rail. The second bolt passes through the central elongated hole and is threaded into the threaded hole at the bottom of the first slide rail. The third bolt passes through the right elongated hole and is threaded into the threaded hole at the bottom of the first slide rail. The first slide rail can rotate around the first bolt at a certain angle, and locking the first, second, and third bolts fixes the position of the lower mounting plate and the first slide rail. The second flexible spring can drive the right end of the first slide rail to always abut against the fastening bolt. The design of the first slide rail, the first slider, and the fastening bolt allows for the adjustment of the front and rear position of the upper contour wheel, while the combination design of the first slide rail and the first bolt allows for the change of the left and right position of the upper contour wheel, thus positioning the upper contour wheel directly below the finishing cutter head. This design provides flexibility in adjusting the position of the upper contour wheel, ensuring its precise alignment with the finishing cutter head and improving machining accuracy and efficiency.

[0042] In at least one embodiment, the lower lifting mechanism includes a bottom contour wheel 41, which is rotatably connected to the lower auxiliary slider.

[0043] Operating procedure: Ensure all components of the device are correctly installed, including the support frame, upper trimming mechanism, lower lifting mechanism, and drive mechanism. Check that key components such as the wire encoder, motor, and ball screw are in good working order. Adjust the front-to-back position and left-to-right angle of the upper contour wheel using the contour wheel position adjustment mechanism to ensure it is coaxial with the finishing cutter head. Front-to-back position adjustment is achieved through the second flexible spring and fastening bolts, while left-to-right position adjustment is achieved by loosening and tightening the first, second, and third bolts. Connect the power supply and start the control board to ensure the device is in standby mode. Place the sheet material in front of the device, with the bottom contour wheel in constant contact with the bottom of the sheet material. The upper edge banding machine adjusts its height in real time based on the previous thickness signal to ensure the trimming effect. The end of the sheet material rests against the upper contour wheel, with the finishing cutter head directly above it, and the trimming work begins. When force is applied to the upper contour wheel, the upper trimming mechanism moves along the upper horizontal bar, changing the wire distance of the wire encoder. The wire encoder transmits the signal to the control board, which then controls the second motor to rotate, causing the bottom contour wheel to move back and forth with the finishing cutter head to ensure accurate sheet thickness.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
