Description

Technical Field

[0002] Edge banding machines are essential in the panel furniture industry. They apply edge banding tape to the edges of panels with adhesive, protecting the panels from chipping and damage, enhancing their appearance, and improving the feel of the furniture. Most existing edge banding machines are straight-line machines, only capable of banding straight-edge panels. Some machines are designed for "handle-less" panels, primarily used for cabinet door handles, drawer handles, and cupboard handles in the furniture industry. Current soft-forming edge banding machines have limited functionality, can only bandage a few types of panels, and produce inconsistent quality. They require significant time for manual adjustments, especially when switching panel types or thicknesses, which is time-consuming and labor-intensive. Furthermore, the appearance and feel of the panels cannot be guaranteed during trimming, scraping, and flat scraping processes. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention include at least the following: The adaptive edge banding equipment for irregularly shaped boards of the present invention achieves efficient, high-quality, and adaptive edge banding processing for complex-shaped boards through its unique modular design and intelligent control. Traditional edge banding equipment generally has poor adaptability to irregularly shaped boards and requires special tooling or a large amount of post-processing. This system is designed specifically to address the pain points of edge banding irregularly shaped sheets. Through contour recognition, servo tracking, dedicated pressing, and fine finishing mechanisms, it effectively overcomes the industry challenge of achieving high-quality edge banding for irregular contours. The central controller dynamically coordinates each module based on input parameters, and the servo tracking system achieves real-time tracking and adjustment of contour movement. This reflects a shift from "mechanization" to "intelligence," improving the controllability, stability, and consistency of the processing. Therefore, the edge banding processing system of this invention has the following significant technical effects: By receiving sheet type, thickness, and key contour feature parameters through the central controller, the system can automatically identify and adapt to irregularly shaped sheets (such as curves, bevels, and concave / convex contours) of different shapes, sizes, and thicknesses, exhibiting high adaptability and flexibility. The servo tracking system is applied to the three key modules of forming milling, pressing, and finishing, ensuring that the actuators such as cutting tools, pressure rollers, and finishing tools strictly follow the movement of the irregular contour of the sheet, maintaining optimal processing contact and position regardless of the complexity of the contour. The forming milling module adopts a "rough milling + finish milling" design. This design ensures that the edge contour of the milled board has extremely high precision and smoothness, achieving accurate contour forming and laying a perfect foundation for subsequent edge banding. The pressing module is equipped with specialized mechanisms: an integrated oblique and straight pressing mechanism that can efficiently handle common straight and oblique edges, and an irregular contour pressing mechanism specifically designed to handle complex irregular contours. This ensures that the edge banding tape achieves uniform, firm, bubble-free, and gap-free adhesion to the edges of boards of different shapes and angles, with particularly significant effects at corners and curves. The multi-stage stepped processing of the finishing module achieves progressive fine processing of the edge banding tape surface, ultimately resulting in a smooth, beautiful, and excellent-feeling joint between the edge banding tape and the board, with clear and burr-free edges. All functional modules are arranged sequentially along the board conveying direction, allowing the board to automatically complete all edge banding processes at each station in sequence, achieving a seamless production process. Each module focuses on a specific process and completes it efficiently, avoiding the time waste caused by the single function or switching of traditional equipment. The high degree of adaptability reduces the need for frequent model changes, machine adjustments, and manual repairs, improving equipment utilization. The human-machine interface design allows operators to input basic sheet parameters and contour features, and the central controller can coordinate and control the entire system, significantly simplifying the complex operation process of edge banding irregularly shaped sheets and reducing the skill requirements for operators.

Detailed Implementation

[0016] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0017] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0018] like Figures 1 to 28 As shown, the present invention provides an adaptive edge banding processing device for irregularly shaped sheets, comprising: The following modules are arranged sequentially along the conveying direction of the sheet material 1: pre-milling module 10, forming milling module 20, chamfering module 30, adhesive application and tape application module 40, pressing module 50, tape cutting module 60, end trimming module 70, rough trimming module 80, and finishing module. Central Controller 100: Configured with a human-machine interface, used to receive the type, thickness and contour feature parameters of the sheet material 1 and coordinate the control of each module; The forming milling module 20 includes a first milling mechanism 21 for performing primary contour milling and reserving a predetermined allowance, and a second milling mechanism 22 for removing the allowance to complete the finishing process. The pressing module 50 includes an integrated oblique and straight pressing mechanism 51 for pressing the oblique and straight edges of the board 1 simultaneously, and an irregular contour pressing mechanism for adapting the irregular contour board 1. The finishing module includes an edge trimming mechanism 91, an edge scraping mechanism 92, a flat edge scraping mechanism 93, and a polishing mechanism 94 for sequentially refining the surface of the edge banding 2. The forming milling module 20, the pressing module 50, and the finishing module are all equipped with a servo tracking system, so that the execution mechanism of each module can synchronously follow the irregular contour movement of the board 1 based on the input contour feature parameters.

[0019] In this embodiment, the working process of the adaptive edge banding processing equipment for irregularly shaped sheet 1 is as follows: Sheet 1 is fed into the conveying mechanism along the guide plate of the edge banding machine. The conveying motor at the end of the edge banding machine drives the conveying mechanism forward. The height of the pressure beam can be set on the edge banding machine operation interface. The height of the pressure beam is set to be consistent with the thickness of sheet 1. After sheet 1 is pressed tightly by the conveying mechanism and the pressure beam, it does not loosen or shift. Before processing, the processing parameters of sheet 1 need to be input into the operation interface of the central controller 100, such as processing type, sheet 1 thickness, groove depth, width, etc., to ensure processing accuracy. Sheet 1 first undergoes pre-milling processing of the surface to be processed through the pre-milling module 10 to eliminate the adverse effects caused by the transportation, cutting, and handling of sheet 1, and improve the texture and aesthetics of the edge banding.

[0020] The sheet metal 1 then enters the first forming milling mechanism. This mechanism can perform forming milling on angled sheet metal 1 and rough milling on "J" and "C" shaped sheet metal 1. During the milling process, the servo tracking system of the first forming milling mechanism synchronously follows the irregular contour movement of the sheet metal 1 based on the input contour feature parameters, thereby realizing the forming processing of different types of sheet metal 1. A 2mm machining allowance is reserved for the sheet metal 1 in this process for subsequent finish milling. The second forming milling mechanism is for finish milling. Its function is to remove ripples, burrs, etc. formed on the sheet metal 1 after rough milling, and also to make the dimensions more accurate after finish milling.

[0021] If the milled shape of board 1 is "J", a chamfering module 30 will be used. The chamfering module 30 will mill the right angle of the straight edge of board 1 into a rounded corner to ensure the feel of board 1 in the "handle-free" position, and at the same time make the edge banding 2 easier to adhere in the subsequent molding and pressing process.

[0022] The adhesive application and tape application module 40 is equipped with two adhesive application mechanisms. The first set of adhesive application mechanism 41 applies adhesive to the board 1, and can apply adhesive to the board 1 with straight edges and then attach the edge banding tape 2 to the board 1. The other set applies adhesive to the edge banding tape 2, mainly for the edge banding of beveled boards 1 and irregularly shaped boards 1. After the edge banding tape 2 is applied with adhesive, it is pressed and attached to the straight edge 11 of the board 1 by the beveled and straight integrated pressing mechanism 51. Then, the edge banding tape 2 is cut by the tape cutting module 60 to reduce the amount of milling for subsequent flat edge trimming. Next, the trimming module 70 cuts off the excess edge banding 2 at the front and back of the wood board, making the two ends of the edge banding 2 flush with the front and back end faces of the wood board. A certain chamfer can also be cut at the two ends of the edge banding 2. Then, the rough trimming module 80 further reduces the milling amount of the secondary trimming R-round corner, thereby obtaining a smoother R-round corner. Then, the board 1 passes through the trimming mechanism 91, the scraping mechanism 92, the flat scraping mechanism 93 and the polishing mechanism 94 in sequence to refine the surface of the edge banding 2. Since the trimming mechanism 91, the scraping mechanism 92 and the flat scraping mechanism 93 are all equipped with servo tracking systems, the execution mechanism of each module synchronously follows the irregular contour movement of the board 1 based on the input contour feature parameters, so as to ensure the accuracy and synchronization of the trimming, scraping and flat scraping processes. The board 1 after edge banding has an excellent feel and appearance.

[0023] The adaptive edge banding equipment for irregularly shaped boards 1 of the present invention achieves efficient, high-quality, and adaptive edge banding processing for complex-shaped boards 1 through its unique modular design and intelligent control. Traditional edge banding equipment generally has poor adaptability to irregularly shaped boards 1 and requires special tooling or a large amount of post-processing. This system is designed specifically to address the pain points of edge banding irregularly shaped sheet material 1. Through contour recognition, servo tracking, dedicated pressing, and fine finishing mechanisms, it effectively overcomes the industry challenge of achieving high-quality edge banding for irregular contours. The central controller 100 dynamically coordinates various modules based on input parameters, and the servo tracking system achieves real-time tracking and adjustment of contour movement. This reflects the transformation from "mechanization" to "intelligence," improving the controllability, stability, and consistency of the processing. Therefore, the edge banding processing system of this invention has the following significant technical effects: By receiving the type, thickness, and key contour feature parameters of sheet material 1 through the central controller 100, the system can automatically identify and adapt to irregularly shaped sheet material 1 of different shapes, sizes, and thicknesses (such as curves, bevels, and concave-convex contours), exhibiting high adaptability and flexibility. The servo tracking system is applied to the three key modules of forming milling, pressing, and finishing, ensuring that the actuators such as cutting tools, pressure rollers, and finishing tools strictly follow the movement of the irregular contour of sheet material 1, maintaining optimal processing contact and position regardless of the complexity of the contour. The forming milling module 20 adopts a "rough milling + fine milling" design. This design ensures that the edge contour of the milled board 1 has extremely high precision and smoothness, achieving accurate contour forming and laying a perfect foundation for subsequent edge banding. The pressing module 50 is equipped with a special mechanism: the inclined and straight integrated pressing mechanism 51 can efficiently handle common straight and inclined edges, and the irregular contour pressing mechanism is specially designed to deal with complex irregular contours. This ensures that the edge banding tape 2 can achieve uniform, firm, bubble-free, and gap-free bonding to the edges of the board 1 with different shapes and angles, especially with significant effects at corners and curves. The multi-level stepped processing of the finishing module (trimming → scraping → flat scraping → polishing) realizes the progressive fine processing of the surface of the edge banding tape 2, ultimately making the joint between the edge banding tape 2 and the board 1 smooth, beautiful, and with excellent feel, and clear edges without burrs. All functional modules are arranged sequentially along the conveying direction of sheet 1. Sheet 1 can automatically complete all edge banding processes at each station in sequence, achieving a seamless production process. Each module focuses on a specific process and completes it efficiently, avoiding the time waste caused by the single function or switching of traditional equipment. The high adaptability reduces the need for frequent model changes, machine adjustments, and manual repairs, improving equipment utilization. The human-machine interface design allows operators to input basic sheet 1 parameters and contour features, and the central controller 100 can coordinate and control the entire system, significantly simplifying the complex operation process of edge banding irregularly shaped sheet 1 and reducing the skill requirements for operators.

[0024] It should be noted that the pre-milling module 10 can smooth out the unevenness or tilting defects on the surface of the sheet 1 to be processed caused by the sheet 1 during the production or cutting process by using a diamond milling cutter, so that the subsequent processing can reach the optimal state. The pre-milling mechanism here is similar in structure and function to the pre-milling mechanism of the traditional straight edge banding machine, so it will not be described in detail here.

[0025] The adhesive application module 40 includes an upper molten adhesive application mechanism 41, a tape feeding mechanism 42, a tape feeding roller 420, a cutting component 421, and a grooving mechanism 43. The upper molten adhesive application mechanism can apply EVA glue and automatically cleans glue clumps and blockages at the edges of the glue tank, thus improving product quality and processing efficiency. The upper molten adhesive application mechanism is existing technology; specifically, refer to patent application number 202121427693.4. The tape feeding mechanism 42 conveys the edge-sealing tape 2 forward via the tape feeding roller 420, and then passes it through the adhesive application roller... The pressing action brings the edge banding tape 2 into contact with the glue application shaft on the glue application mechanism 41, allowing the glue on the glue application shaft to be applied to the edge banding tape 2. It can then be cut by the cutting component 421. A grooving mechanism 43 is provided at the beginning of the tape feeding position. The grooving mechanism 43 includes a grooving motor 431, a grooving saw blade 432 mounted on the output shaft of the grooving motor 431, a first adjusting shaft 433 for adjusting the height of the grooving motor 431 in the Z-axis direction, and a second adjusting shaft 434 for adjusting the depth of the grooving by the grooving saw blade 432 on the edge banding tape 2.

[0026] The slicing module 60 includes a base 601, a Y-axis guide shaft 602, a slicing slide 603, a slicing advance / retract cylinder 604, a slicing motor 605, a slicing mounting base 606, a height adjustment shaft 607, a slicing saw blade 608, a retraction limit screw 609, an extension limit saw blade screw 610, a saw blade height adjustment handle 611, a counter 612, and a saw blade guard 613. The Y-axis guide shaft 602 is fixed to the base 601 and interacts with a linear bearing (not shown in the figure) in the slicing slide 603. In conjunction with this, the cutting advance / retract cylinder 604 is fixed to the base 601, and its piston rod is fixed to the cutting slide 603, enabling the cutting motor 605 to move in the Y-axis direction. An extension limit screw is fixed to a threaded hole in the cutting slide 603, limiting the extension position of the piston rod of the cutting advance / retract cylinder 604 by the characteristic that the screw head is larger than the hole in the base 601. A retraction limit screw 609 is installed in the threaded hole of the base 601 and fixed with a nut, limiting the retraction position of the piston rod of the cutting advance / retract cylinder 604. The cutting mounting base 606 and the cutting motor 605 are mounted on the cutting slide 603. The height adjustment shaft 607 is threaded and mates with the threaded hole in the cutting slide 603. Therefore, turning the saw blade height adjustment handle 611 can adjust the distance between the bottom of the cutting saw blade 608 and the top of the wooden board, achieving the function of cutting the edge banding tape 2, reducing the milling amount for subsequent edge trimming.

[0027] The trimming module 70 is used to cut off the excess edge banding 2 at the front and back of the wooden board, so that the two ends of the edge banding 2 are flush with the front and back end faces of the wooden board, and can also cut a certain chamfer at the two ends of the edge banding 2. The trimming module 70 is similar in structure and function to the trimming mechanism of the traditional straight edge banding machine, so it will not be described in detail here.

[0028] The function of the rough trimming module 80 is to reduce the milling amount of the secondary trimming R-corner, thereby obtaining a smoother R-corner; at the same time, in order to meet the need to trim straight edges without trimming R-corners, a primary trimming mechanism 91 is added; the rough trimming module 80 here is similar in structure and function to the rough trimming mechanism of the traditional straight edge sealing machine, so it will not be described in detail here.

[0029] In a preferred embodiment, the first milling mechanism 21 includes: Milling base 210; The Z-axis motion mechanism is mounted on the milling base 210 and is used to provide motion along the Z-axis direction; The Y-axis motion mechanism is mounted on the moving part of the Z-axis motion mechanism and is used to provide motion along the Y-axis direction, wherein the Y-axis direction is perpendicular to the Z-axis direction. The milling execution unit 217 is mounted on the moving part of the Y-axis motion mechanism; The drive control system is controlled by the central controller 100. The drive control system includes a first servo control component 211 for controlling the Z-axis motion mechanism and a second servo control component 214 for controlling the Y-axis motion mechanism. The position of the milling execution unit 217 is controlled by the first servo control component 211 and the second servo control component 214 so that the milling execution unit 217 performs primary milling machining on the contour trajectory of the plate 1.

[0030] In this embodiment, the first milling mechanism 21 performs rough milling on the plate 1 to be processed. The first servo control component 211 precisely controls the position of the milling execution unit 217 in the Z-axis direction, and the second servo control component 214 precisely controls the position of the milling execution unit 217 in the Y-axis direction. During the milling process, the first servo control component 211 and the second servo control component 214 drive the milling execution unit 217 to move along the required contour trajectory of the plate 1, thereby realizing the forming processing of different types of plate 1. The plate 1 will reserve a processing amount of 2mm in this process for subsequent fine milling.

[0031] Specifically, the Z-axis motion mechanism includes a Z-axis milling guide 212 disposed on the milling base 210 and extending along the Z-axis direction, and a Z-axis milling slide 213 slidably connected to the Z-axis milling guide 212. The Z-axis milling slide 213 is connected to the output end of the first servo control component 211. The Y-axis motion mechanism includes a Y-axis milling guide 215 mounted on the Z-axis milling slide 213, and a Y-axis milling slide 216 slidably connected to the Y-axis milling guide 215. The Y-axis milling slide 216 is connected to the output end of the second servo control component 214. The milling execution unit 217 is mounted on the Y-axis milling slide 216.

[0032] The first servo control component 211 and the second servo control component 214 have the same structure, and the first servo control component 211 and the second servo control component 214 constitute the servo tracking system of the forming milling module 20. The second servo control component 214 includes a second Y-axis servo motor 2140, a second Y-axis coupling 2141, a Y-axis motor mount 2142, a second Y-axis nut 2143, a second Y-axis lead screw 2144, and a Y-axis nut fixing seat 222. The second Y-axis servo motor 2140 is fixed on the Y-axis motor mount 2142, and the output shaft of the Y-axis servo motor is connected to the second Y-axis lead screw 2144 through the second Y-axis coupling 2141. The second Y-axis nut 2143 is connected to the second Y-axis lead screw 2144 through the second Y-axis coupling 2141. The second Y-axis lead screw 2144 is threaded, the Y-axis nut fixing seat 222 is connected to the second Y-axis nut 2143, and the Y-axis nut fixing seat 222 is connected to the Y-axis milling slide 216 (the Z-axis nut fixing seat 221 of the first servo control component 211 is connected to the Z-axis milling slide 213). The working principle of the second servo control component 214 is as follows: the second Y-axis servo motor 2140 serves as the power source, and its rotation is transmitted to the second Y-axis lead screw 2144 through the second Y-axis coupling 2141. When the second Y-axis lead screw 2144 rotates, it transmits the rotational motion to the second Y-axis nut 2143. The second Y-axis nut 2143 is rigidly fixed to the Y-axis milling slide 216 directly connected to it. The Y-axis milling slide 216 cooperates with the Y-axis milling guide rail 215. The design of the guide rail pair strictly restricts the rotational freedom of the second Y-axis nut 2143 and the Y-axis nut fixing seat 222 connected to it, forcing the second Y-axis nut 2143 to only move linearly along the guiding direction of the Y-axis milling guide rail 215. Therefore, the rotation of the second Y-axis lead screw 2144 is ultimately converted into high-precision linear displacement of the Y-axis milling slide 216 along the Y-axis, thereby accurately positioning the milling execution unit 217 on it and achieving precise position control. The first servo control component 211 and the second servo control component 214 provide high transmission efficiency and high-precision positioning through the application of motors and lead screw-nut pairs.

[0033] In a preferred embodiment, the milling execution unit 217 includes a first milling motor 2170 and a first milling cutter 2171 and a second milling cutter 2172 mounted on its output shaft; The milling cutter 2171 and the milling cutter 2172 are spaced apart along the Z-axis direction; The first milling motor 2170 is connected to the moving part of the Y-axis motion mechanism via the milling motor mounting base 218; It also includes an angle adjustment mechanism, which comprises: Adjustment block 219 fixed below the moving part of the Y-axis motion mechanism; The first adjusting screw passes through the adjusting block 219 and engages with the first threaded hole of the milling motor mounting base 218; The second adjusting screw passes through the milling motor mounting base 218 and engages with the second threaded hole of the adjusting block 219; The tilt angles of milling cutter 2171 and milling cutter 2172 in the YZ plane are adjusted by coordinating the adjustment of the first and second adjusting screws.

[0034] In this embodiment, the moving part of the Y-axis motion mechanism is the Y-axis milling slide 216. By installing milling cutter 1 2171 and milling cutter 2172 at the output end of the first milling motor 2170, and with milling cutter 1 2171 and milling cutter 2172 spaced apart along the Z-axis, it can accommodate milling of plates 1 of different thicknesses. By coordinating the adjustment of the first and second adjusting screws, the angles of milling cutter 1 2171 and milling cutter 2172 in the YZ plane can be adjusted to meet the milling requirements of different plates 1.

[0035] Specifically, a dust-collecting cover 220 is provided on the side of the first milling motor 2170. The dust-collecting cover 220 can remove the debris and dust generated during the milling process through an external dust removal device, so as to avoid damage to the human body, products, equipment, etc.

[0036] The second milling mechanism 21 is basically the same in structure as the first milling mechanism 22, except that the output end of the second milling motor only has one milling cutter. After rough milling, the sheet 1 will have a 2mm allowance for finish milling, which can ensure that the dimensions of the sheet 1 are met and the processing quality of the processed surface of the sheet 1 is good, thus improving the quality of the subsequent pressing process. By using two processes, roughing and finishing, the milling accuracy of the sheet 1 is improved, and the stability of the subsequent edge sealing process is increased.

[0037] In a preferred embodiment, the chamfering module 30 includes: Chamfered base 301; Z-axis servo control component 302 is mounted on the chamfered base 301 and is used to provide Z-axis direction movement; Z-axis chamfering guide shaft 303 is disposed on the chamfering base 301 and extends along the Z-axis direction; Z-axis chamfered slide block 304 is slidably connected to the Z-axis chamfered guide shaft 303 and is configured to be driven by the Z-axis servo control component 302 to move along the Z-axis; The Y-axis forward / backward control component 305 is mounted on the chamfered base 301 and is used to provide movement in the Y-axis direction. The Y-axis chamfered guide shaft 306 is connected to the Z-axis chamfered slide block 304 and extends along the Y-axis direction; The Y-axis chamfered slide block 307 is slidably connected to the Z-axis chamfered guide shaft 303 and is configured to be driven by the Y-axis advance and retreat control component 305 to move along the Y-axis; The chamfering motor 308 is connected to the Y-axis chamfering slide 307; The chamfering tool 309 is mounted on the output shaft of the chamfering motor 308.

[0038] In this embodiment, the chamfering module 30 is used to chamfer the lower right-angled edge of the plate 1. Its function is to make the edge banding tape 2 better adhere to the plate 1 during the subsequent pressing process, and also to remove the sharp edges and burrs of the plate 1 after milling. The chamfering cutter 309 is controlled to move up and down along the Z-axis by the Z-axis servo control component 302 to adapt to the processing of plates 1 of different thicknesses. The chamfering motor 308 is moved forward and backward by the Y-axis advance and retreat control component 305, thereby adjusting the position of the chamfering cutter 309 in the Y-axis direction.

[0039] Specifically, the Z-axis servo control component 302 can be a motor lead screw mechanism, and the Y-axis advance / retreat control component 305 is a cylinder. A chamfering cover 310 is installed on the outside of the chamfering tool 309.

[0040] Specifically, when the milled shape of the board 1 is "J", a chamfering module 30 is used. The chamfering module 30 is controlled by the Y-axis advance and retreat control component 305 to determine whether it needs to be in working state. When the piston rod of the Y-axis advance and retreat control component 305 is extended, it is in non-working state, and when it is retracted, it is in the opposite state. The height of the module is precisely adjusted by the Z-axis servo control component 302 to automatically adapt to different thicknesses of the board 1. When the board 1 passes through the chamfering module 30, the chamfering motor 308 drives the chamfering cutter 309 to rotate, milling the right angle of the straight edge of the board 1 into a rounded corner, ensuring the feel of the board 1 in the "handle-free" position, and also making the edge banding tape 2 easier to adhere in the subsequent molding and pressing.

[0041] In a preferred embodiment, the inclined and straight integrated pressing mechanism 51 includes: Slanted and straight pressing base 510; The pressing advance and retreat control component 511 is installed on the inclined straight pressing base 510 and is used to provide advance and retreat movement in the Y-axis direction; The pressing slide 512 is slidably connected to the inclined straight pressing base 510 and is configured to be driven by the pressing advance and retreat control component 511 to move along the Y-axis; The pressing and retracting base 513 is connected to the pressing slide 512; Several vertically arranged straight-edge pressing wheels 514 and several inclined-edge pressing wheels 515 are arranged sequentially on the pressing advance and retreat base 513. Each of the straight-edge pressing rollers 514 and each of the inclined-edge pressing rollers 515 is respectively equipped with a straight-edge driving mechanism 516 and an inclined-edge driving mechanism 517 for driving them to move toward the plate 1.

[0042] In this embodiment, the integrated oblique and straight pressing mechanism 51 is mainly used for pressing the oblique angled plate 1, and can also press the straight edge of the irregularly shaped plate 1. The pressing advance and retreat control component 511 is used to control the advance and retreat movement of the entire mechanism along the Y-axis, so as to ensure that all pressing rollers are tightly pressed against the edge sealing tape 2, and the pressing rollers will not jump due to machine vibration or other problems. By controlling the straight edge pressing roller 514 and the oblique edge pressing roller 515 to move towards the plate 1 through the straight edge driving mechanism 516 and the oblique edge driving mechanism 517 respectively, the precise pressing of the straight edge and oblique edge of the plate 1 can be achieved.

[0043] In a preferred embodiment, the irregular contour pressing mechanism includes a slot pressing component 52 and a first straight edge pressing component 53 arranged sequentially; wherein, the slot pressing component 52 includes: Two parallel servo lifting plates 521 are configured to be able to move up and down along the Z-axis and move forward and backward along the Y-axis. The support shaft 522 is connected between the two servo lifting plates 521; Several sets of first pressing rollers 527 assemblies are installed on the support shaft 522; Each set of first pressing rollers 527 assemblies includes a fixed support 523 sleeved on a support shaft 522, a lifting servo unit 524 mounted on the fixed support 523, a Y-axis slide 525 connected to the output end of the lifting servo unit 524, a horizontal servo unit 526 connected to one end of the Y-axis slide 525, and a first pressing roller 527 connected to the other end of the Y-axis slide 525. An adjustment mechanism is used to ensure that the working surface of the first pressing roller 527 and the surface of the edge banding 2 form a preset interference fit. The first straight edge pressing assembly 53 includes a support plate 531, a plurality of second pressing roller 533 assemblies mounted on the support plate 531, and a Y-axis switching assembly 532 that drives the support plate 531 to move forward and backward along the Y-axis direction. Each set of second pressing roller 533 assemblies includes a second pressing roller 533 and a Y-axis forward and backward assembly 534 that drives the second pressing roller 533 to move along the Y-axis direction.

[0044] In this embodiment, the irregular contour pressing mechanism is mainly for pressing irregularly shaped plates 1 such as "J" and "C". It mainly relies on the pressing roller to squeeze each part of the plate 1, so that the edge banding 2 covered with glue is tightly attached to the groove of the plate 1. Specifically, the support shaft 522 is equipped with ten sets of first pressing rollers 527 assemblies, named respectively from the direction of travel of the board 1 as the first pressing roller assembly, the second pressing roller assembly, up to the tenth pressing roller assembly. Each pressing roller assembly has specific pressing positions required during the pressing process, as follows: the pressing position of the first pressing roller assembly corresponds to point S1 of the edge banding tape 2; the second and third pressing roller assemblies correspond to point S2 of the edge banding tape 2; the fourth and fifth pressing roller assemblies correspond to point S3 of the edge banding tape 2; the sixth pressing roller assembly corresponds to point S4 of the edge banding tape 2; the seventh pressing roller assembly corresponds to point S5 of the edge banding tape 2; the eighth pressing roller assembly corresponds to point S6 of the edge banding tape 2; and the ninth and tenth pressing roller assemblies correspond to point S7 of the edge banding tape 2. These corresponding positions can be referenced. Figure 13 Each pressing roller assembly requires adjusting the distance between the first pressing roller 527 and the edge sealing tape 2 to -0.5mm. It's important to note that this 0.5mm means: when the first pressing roller 527 and the edge sealing tape 2 are just tightly fitted (0mm distance), it still needs to be adjusted another 0.5mm towards the edge sealing tape 2 to ensure sufficient pressure from the first pressing roller 527. Specifically, this is achieved through an adjustment mechanism that creates a preset interference fit between the working surface of the first pressing roller 527 and the surface of the edge sealing tape 2. The adjustment mechanism includes a first limiting screw 5230 and a second limiting screw 5231. The first limiting screw 5230 adjusts the height of the first pressing roller 527 in the Z-axis direction, and the second limiting screw 5231 adjusts the position of the first pressing roller 527 in the Y-axis direction, thus creating the preset interference fit between the working surface of the first pressing roller 527 and the surface of the edge sealing tape 2.

[0045] The slot pressing assembly 52 in this embodiment also includes a servo lifting assembly 528 and a slot switching assembly. The servo lifting assembly 528 is used to drive the servo lifting plate 521 to move up and down along the Z-axis. The servo lifting assembly 528 can be a motor screw mechanism. The slot switching assembly drives the servo lifting assembly 528 to move forward and backward along the Y-axis. Specifically, the slot switching assembly is a slot switching cylinder 529. The piston rod of the slot switching cylinder 529 is connected to the servo base plate of the servo lifting assembly 528. When the piston rod of the slot switching cylinder 529 is in the extended state, it is suitable for forming and pressing "J" shaped plates. When the piston rod of the slot switching cylinder 529 is in the retracted state, it is suitable for forming and pressing "C" shaped plates.

[0046] During the forming and pressing process of the board 1, a support assembly is provided below the board 1, with several bottom limiting support wheels 55 above it to support the board 1 and prevent poor pressing due to deformation or displacement of the board 1 during the pressing process. Two hot air guns are provided at the entrance of the groove pressing assembly 52, and several heat lamps (not shown in the figure) are also provided above the first pressing wheel 527 assembly. These are mainly used to heat the edge banding tape 2, softening it and making it easier to shape under the pressure of the first pressing wheel 527. As the board 1 enters the irregular contour pressing mechanism, to increase the success rate of the edge banding tape 2 adhering to the board 1, a set of support wheel assemblies and several sets of second straight edge pressing assemblies 54 are added below the board 1. The several sets of second straight edge pressing assemblies 54 are used to press the straight edges of the bottom contour of the board 1. Each set of second straight edge pressing assemblies 54 includes a pressing block 541, a pressing seat 542, and a pressure adjustment group. The pressure adjustment assembly includes a pressing guide shaft 543, an adjusting rod 544, an elastic element 545, and an adjusting member 546. The pressing block 541 is provided with a plurality of first guide holes 5410 and at least one adjusting hole 5411. The pressing seat 542 is provided with a second guide hole 5420 corresponding to the position of the first guide hole 5410 and an opening 5421 corresponding to the position of the adjusting hole 5411. The two ends of the pressing guide shaft 543 respectively cooperate with the first guide hole 5410 and the second guide hole 5420. The elastic element 545 passes through or surrounds the adjusting rod 544 and is configured to provide pre-pressure. One end of the adjusting rod 544 is threadedly engaged with the adjusting hole 541, and the other end of the adjusting rod 544 extends out from the opening 5421 and cooperates with the adjusting member 546, so as to adjust the pressure of the pressing block 541 on the sealing tape 2 by rotating the adjusting member 546. When the board 1 passes through, the pressure of the pressing block 541 on the edge banding 2 can be adjusted by turning the adjusting component 546 to achieve different bonding effects.

[0047] The first straight edge pressing component 53 is mainly used for pressing the straight edge of the irregular plate 1. The straight edge can be pressed and bonded by the inclined straight integrated pressing mechanism 51, but the straight edge inside the groove cannot be pressed. Therefore, the first straight edge pressing component 53 here can press the straight edge 12.

[0048] In this embodiment, the support plate 531 of the first straight edge pressing component 53 is slidably mounted on the first straight edge pressing base 530. The support plate 531 is configured to be driven to move forward and backward along the Y-axis direction by the Y-axis switching component 532. The Y-axis switching component 532 achieves the forward and backward distance along the Y-axis direction through the cooperation of the forward and backward limit block 535 and the forward and backward adjustment screw 536. The several sets of second pressing rollers 533 components in this embodiment are named first pressing roller 527, second pressing roller 533, and so on, up to the sixth pressing roller, starting from the direction of travel of the plate 1. The first two sets of pressing rollers are for pressing straight edge 11, and the last four sets of pressing rollers are for pressing straight edge 12. Their specific structures are not described in detail.

[0049] In a preferred embodiment, both the trimming mechanism 91 and the scraping mechanism 92 include a first moving component, a second moving component, and an execution component. The driving end of the first moving component is connected to the second moving component, and the execution component is fixed to the driving end of the second moving component. The execution component includes an execution cutter. The first moving component is used to drive the execution cutter to move closer to or away from the edge banding 2 of the board 1, and the second moving component is used to drive the execution component to rotate around a predetermined axis, which is perpendicular to the plane where the board 1 is located.

[0050] In this embodiment, the relative position of the cutting tool and the plate 1 can be automatically adjusted by the first moving component and the second moving component, and the irregular plate 1 can be followed and processed, which can effectively reduce labor costs and improve processing speed and production efficiency, thus meeting the needs of automated production.

[0051] Specifically, the trimming mechanism 91 further includes a trimming bracket 910, on which a trimming guide shaft 911 is provided. The trimming guide shaft 911 extends along the Z-axis. The first moving component includes a Z-axis trimming slide 912 slidably connected to the trimming guide shaft 911, a Y-axis lead screw seat 913 connected to the Z-axis trimming slide 912, a Y-axis trimming lead screw nut 914 connected to the Y-axis lead screw seat 913, a Y-axis ball screw 915 threadedly engaged with the Y-axis trimming lead screw nut 914, and a Y-axis trimming servo motor 916 connected to the Y-axis ball screw nut 915. The second moving component includes a Y-axis trimming slide 917 connected to the Z-axis trimming slide 912, a trimming machine base 918 connected to the Y-axis trimming slide 917, and a Z-axis trimming servo motor 916 driving the trimming machine base 918 to rotate around the Z-axis rotation axis. 19. A trimming motor 9120 is mounted on a trimming machine base 918, and a trimming cutter 9121 is mounted on the output end of the trimming motor 9120. The top and bottom of the Y-axis trimming slide 917 are respectively provided with an upper support plate 9126 and a lower support plate 9127. The top of the trimming machine base 918 is connected to the upper support plate 9126 through an upper rotating shaft 9124. The upper end of the upper rotating shaft 9124 passes through the upper support plate 9126 and is connected to the output end of the Z-axis trimming servo motor 919. The bottom of the trimming machine base 918 is connected to the lower support plate 9127 through a lower rotating shaft 9125. Therefore, when the Z-axis trimming servo motor 919 drives the upper rotating shaft 9124 to rotate, the rotation of the upper rotating shaft 9124 drives the trimming machine base 918 to rotate around the axis of the upper rotating shaft 9124, thereby realizing the rotation of the trimming motor 9120 and the trimming cutter 9121.

[0052] Specifically, a contour wheel 9122 and a limit bearing 9123 are installed on the trimming machine base 918. The contour wheel 9122 is located on one side of the trimming cutter 9121, and the limit bearing 9123 is located on the other side of the trimming cutter 9121. Since the contour wheel 9122 and the limit bearing 9123 are fixed on the trimming machine base 918, the limit bearing 9123 and the contour wheel 9122 will also rotate together with the trimming cutter 9121.

[0053] The trimming mechanism 91 in this embodiment can perform fine trimming on various irregularly shaped sheet materials 1. Only one example is given here. Figure 2Taking the shape of sheet 1 as an example, the specific process is as follows: In the preparation stage, both the Z-axis trimming servo motor 919 and the Y-axis trimming servo motor 916 are in the pre-set initial position. Before the mechanism starts, the positions of the contour wheel 9122 and the limit bearing 9123 need to be adjusted according to the fine trimming requirements of sheet 1 so that the rounded corners of the finely trimmed sheet 1 meet the factory requirements. The parameters can be determined by the position of the tool at this time. When sheet 1 is close to the trimming tool 9121, because the cutting edge of the trimming tool 9121 is arc-shaped, the trimming motor 9120 drives the trimming tool 9121 to rotate. Therefore, the right-angled edge of the edge banding 2 will be milled into an arc shape by the trimming tool 9121. Under the action of the limit bearing 9123 and the contour wheel 9122, not only can the stability of sheet 1 be guaranteed, but also the tool can work stably during the processing.

[0054] When the sheet material 1 is finished to the arc and second bevel, the Z-axis trimming servo motor 919 controls the rotation angle of the upper rotating shaft 9124. Simultaneously, the Y-axis trimming servo motor 916 works in coordination with the Z-axis, ensuring that the cutting edge of the trimming tool 9121 remains in close contact with the edge banding 2 of the sheet material 1. Since the limit bearing 9123 and the contour wheel 9122 are mounted on the trimming machine base 918, they also rotate along with the trimming tool 9121. This design offers several advantages. To ensure that the stress points of the sheet material 1 and the trimming cutter 9121 are always aligned with the center of the contour wheel 9122, the sheet material 1 is made more stable during processing, resulting in a more aesthetically pleasing product. Finally, when the trimming cutter 9121 enters the end of the bevel, the Z-axis trimming servo motor 919 controls the angle of the upper rotation axis 9124 to follow the sheet material 1 into the processing of the last straight edge. The processing principle and process of the last segment are the same as those of the first segment on the straight edge, so they will not be described again here. The mechanism can rotate ±25° at the position of processing the straight edge, which allows for the processing of more irregularly shaped sheet materials 1.

[0055] It should be noted that the working principle of the scraping mechanism 92 and the trimming mechanism 91 is the same, so it will not be described in detail here.

[0056] In a preferred embodiment, the flat edge scraping mechanism 93 includes: The flat scraping assembly 931 includes a flat scraping cutter 9310 for scraping the edge banding tape 2; A servo rotation component 932 is connected to the flat scraping component 931 and is used to drive the flat scraping component 931 and its flat scraping cutter 9310 to rotate around the Z-axis rotation line. A servo advance / retreat component, which is connected to the servo rotation component 932, is used to drive the servo rotation component 932 and the flat scraping component 931 to move along the Y-axis direction; The servo rotation component 932 and the servo advance / retreat component are configured to dynamically adjust the cutting edge orientation of the flat scraping tool 9310 in response to changes in the irregular contour edge of the board 1, so that the cutting edge of the flat scraping tool 9310 adapts to the shape of the irregular contour edge of the board 1 it contacts, so as to perform contour-following flat scraping on the edge banding 2 on the irregular contour edge of the board 1.

[0057] In this embodiment, the servo rotation assembly 932 includes a support body 9320, a rotating shaft 9321, a Z-axis flat scraping servo motor 9322, a Z-axis planetary reducer 9323, a Z-axis coupling 9324, a bearing assembly 9325, and a servo mounting base 9326. The support body 9320 has multiple bearing cavities spaced apart along the Z-axis direction. Each bearing assembly 9325 is disposed within a bearing cavity to support the rotating shaft 9321 in rotating around the Z-axis rotation line. 321 extends through the support body 9320 and along the Z-axis. A servo mounting base 9326 is installed on the top of the support body 9320. A Z-axis coupling 9324 is installed inside the servo mounting base 9326. The output end of the Z-axis trimming servo motor 919 is connected to the input end of the Z-axis planetary reducer 9323. The Z-axis planetary reducer 9323 is connected to the first end of the rotating shaft 9321 through the Z-axis coupling 9324. The second end of the rotating shaft 9321 is connected to the flat scraping assembly 931.

[0058] In this embodiment, the Z-axis flat scraping servo motor 9322 is used to control the rotation of the rotating shaft 9321, precisely controlling the orientation of the scraping tool, ensuring the stability of the scraping tool in the processing, comprehensively guaranteeing the flat scraping quality and adapting to the flat scraping treatment of various irregularly shaped plates 1.

[0059] The servo advance / retreat assembly includes an advance / retreat base 9330, a Y-axis advance / retreat slide 9331, an advance / retreat servo motor 9332, an advance / retreat lead screw 9333, a first lead screw nut 9334, a first Y-axis coupling 9335, and a guide optical shaft 9336. One end of the advance / retreat lead screw 9333 is connected to the output end of the advance / retreat servo motor 9332 through the first Y-axis coupling 9335. The first lead screw nut 9334 is threadedly connected to the advance / retreat lead screw 9333. The Y-axis advance / retreat slide 9331 is connected to the first lead screw nut 9334. Both ends of the guide optical shaft 9336 are connected to the advance / retreat base 9330. The Y-axis advance / retreat slide 9331 has a guide hole inside, and the linear bearing is disposed in the guide hole and used to cooperate with the guide optical shaft 9336.

[0060] The flat edge scraping assembly 931 includes a flat edge scraping base 9311, a tool mounting base 9312, and a lifting cylinder 9313 for driving the flat edge scraping base 9311 to move up and down along the Z-axis. The flat edge scraping tool 9310 is mounted on the tool mounting base 9312, and the tool mounting base 9312 is connected to the flat edge scraping base 9311. The output end of the lifting drive unit is connected to the flat edge scraping base 9311, and the fixed end of the lifting cylinder 9313 is connected to the rotating shaft 9321.

[0061] The flat scraping mechanism 93 of this embodiment can perform flat scraping treatment on various irregularly shaped plates 1. Only one example is given here. Figure 2 Take the shape of board 1 as an example.

[0062] During the preparation phase, the forward / backward servo motor 9332 controls the flat scraping assembly 931 to reach the preset position, and the Z-axis flat scraping servo motor 9322 controls the flat scraping base 9311 below the rotating shaft 9321 to reach the preset angle position. At this time, the piston rod of the lifting cylinder 9313 is in the initial retracted state. When the edge banding machine starts to feed the board, the piston rod of the lifting cylinder 9313 is pushed out through the edge banding machine operation interface, so that the flat scraping cutter 9310 enters the working state until the feeding of the board is completed. Before the mechanism works, the parameters of the irregularly shaped board 1 need to be entered into the operation interface, such as the length and width of the irregular groove. There is a limit switch sensor in front of this mechanism for measuring the width of the board 1 and reading the position of the board 1 on the edge banding machine conveyor belt, which can be used as a signal to start the device.

[0063] Before board 1 enters the first stage of flat scraping straight edge, the flat scraping cutter 9310 contacts the board and begins to flat scrape the first straight edge. When board 1 moves to the beveled edge position, the Z-axis flat scraping servo motor 9322 controls the rotation of the flat scraping cutter 9310, so that the edge of the flat scraping cutter 9310 in contact with board 1 always remains perpendicular. When the flat scraping cutter 9310 rotates, the forward and backward servo motor 9332 also works in coordination to keep the midpoint of the flat scraping cutter 9310 in contact with the edge of board 1. When the flat scraping cutter 9310 enters the end of the bevel under the coordinated control of the Z-axis flat scraping servo motor 9322 and the forward and backward servo motor 9332, the Z-axis flat scraping servo motor 9322 gradually straightens the angle of the flat scraping cutter 9310 along the edge of board 1, and the forward and backward servo motor 9332 stops working, and then enters the final stage.

[0064] The third stage of flat scraping straight edges is similar to the first stage, both using straight edges as the reference. It should be noted that after the flat scraping blade 9310 has passed through the board 1, the Y-axis needs to be restored to the position of the preparation stage to prepare for the arrival of the next board.

[0065] The flat scraping mechanism 93 controls the flat scraping component 931 to move along the Y-axis to a preset position via the servo advance and retreat mechanism 933. The servo rotation component 932 drives the flat scraping component 931 to rotate around the Z-axis rotation line to adjust the cutting edge orientation of the flat scraping cutter 9310. By responding to the changes in the irregular contour edge of the board 1, the cutting edge orientation of the flat scraping cutter 9310 is dynamically adjusted, so that the cutting edge of the flat scraping cutter 9310 adapts to the shape of the irregular contour edge of the board 1 it contacts, so as to perform contour flat scraping on the edge sealing strip 2 on the irregular contour edge of the board 1, thereby realizing the flat scraping treatment of the irregular contour edge of the board 1. Compared with the fixed flat scraping, this device can ensure the flat scraping quality in all aspects and adapt to the flat scraping treatment of various irregular board 1, with stronger adaptability.

[0066] The servo advance / retreat mechanism 933 and the servo rotation component 932 work together through the central controller 100 to track and scrape the irregular contour edge of the sheet 1.

[0067] As a preferred embodiment, refer to Figure 27 The polishing mechanism 94 includes: The polishing base 941 is provided with a polishing guide shaft 944 extending along the Z-axis direction. The lower polishing assembly 942 is slidably connected to the guide shaft and is configured to move only along the Z-axis direction; The upper polishing assembly 943 is disposed above the lower polishing assembly 942 and slidably connected to the polishing guide shaft 944, and is configured to move along the Z-axis and Y-axis directions. A lower height adjustment component is used to adjust the height of the lower polishing component 942 in the Z-axis direction; An upper height adjustment component is used to adjust the height of the upper polishing component 943 in the Z-axis direction; Y-axis drive assembly 945 is used to drive the upper polishing assembly 943 to move along the Y-axis direction.

[0068] In this embodiment, the polishing mechanism 94 removes the edge burrs of the edge banding tape 2 and the residual glue between the edge banding tape 2 and the wood board, making the edge of the wood board cleaner and smoother. Regardless of whether the board 1 is straight-edged, "J"-shaped, or "C"-shaped, the shape of its bottom surface will not change. Therefore, the two sets of lower polishing components 942 in the polishing mechanism 94 are fixed. By adding a Y-axis drive component 945 on the Y-axis, the straight edge 12 is tracked for contour polishing. Specifically, the lower height adjustment component is a lower limit screw 947, which adjusts the height of the lower polishing component 942 in the Z-axis direction. The upper height adjustment component is an upper limit screw 946, one end of which is fixed to the hanger, and the other end is threaded to the adjustment seat of the upper polishing component 943.
