Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0073] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0074] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0075] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0076] Figure 1 This is a schematic diagram of the structure of the irregular edge banding machine shown in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of the air flotation trimming mechanism 4 shown in the embodiments of this application.

[0077] See Figure 1 and Figure 2 The present invention provides an irregular edge banding machine, including a frame 1 and a rocker arm 2, an edge banding assembly 3, an air flotation edge trimming mechanism 4 and a numerical control display device 5 mounted on the frame 1;

[0078] The rocker arm 2 is equipped with a suction cup 20 for fixing the plate 6. The plate 6 is transported by the rocker arm 2 to the edge sealing assembly 3 and the air flotation edge trimming mechanism 4 for processing.

[0079] The edge banding assembly 3 is used to band the edges of the sheet 6;

[0080] The air-floating trimming mechanism 4 includes two trimming components 40. Each trimming component 40 includes a trimming motor 400 and an air-floating column 401. The motor shaft of the trimming motor 400 is equipped with a trimming blade 402. The air-floating column 401 is located on one side of the trimming blade 402, and the two trimming blades 402 are arranged opposite to each other. The two air-floating columns 401 are arranged opposite to each other and form a gap for the board 6 to pass through. The air-floating column 401 sprays airflow onto the surface of the board 6 through an air passage.

[0081] The numerical control display device 5 is connected to a foot switch, and the numerical control display device 5 and the foot switch control the edge sealing assembly 3 and the air-float trimming mechanism 4 to work.

[0082] When applying the technical solution of this utility model, after the irregular edge banding machine is powered on, parameters such as the thickness of the board 6 and the length of the edge banding tape are input into the CNC display device 5. The operator places the board 6 on the suction cup 20, presses the foot switch to activate the suction cup 20, and fixes the board 6 by negative pressure adsorption. The rocker arm 2 is manually pushed to move the board 6 to the edge banding starting position of the edge banding assembly 3. The edge banding foot switch is pressed, and the board 6 rotates around the axis of the suction cup 20 to realize the edge banding work. Under the control of the CNC display device 5, the rocker arm 2 transports the board 6 to the air flotation trimming mechanism 4. The trimming foot switch is pressed to realize the trimming work.

[0083] The irregular edge banding machine provided by this utility model simplifies the process of fixing irregularly shaped plates 6 by using suction cups 20 on the rocker arm 2. The plate 6 is stabilized by air jetting air through the air float column 401, avoiding manual adjustment and improving the positioning accuracy of the plate 6. The edge banding and trimming of the plate 6 are integrated on the frame 1, reducing the number of times the plate 6 is handled, shortening the processing cycle of the plate 6, and improving the production effect. The air float trimming mechanism 4 forms a gap through the air float column 401, which can adapt to plates 6 of different thicknesses, and is especially suitable for irregularly shaped plates 6 such as round table boards and L-shaped boards.

[0084] Understandably, foot switches are a mature application in this field, and will not be elaborated upon here.

[0085] Furthermore, such as Figures 3 to 6 As shown, the edge sealing assembly 3 includes a rotary table 30, a tape feeding assembly 31, an adhesive application assembly 32, a pressing assembly 33, and a feeding assembly 34. The rotary table 30 is mounted on the frame 1. The tape feeding assembly 31, the adhesive application assembly 32, and the pressing assembly 33 are mounted on the rotary table 30. The feeding assembly 34 is located on one side of the rotary table 30.

[0086] The tape feeding assembly 31 is used to feed the edge sealing tape;

[0087] The adhesive application assembly 32 is used to apply adhesive to the edge banding tape;

[0088] The pressing component 33 is used to seal the edges of the board 6;

[0089] The feeding assembly 34 is used to drive the plate 6 to rotate around the axis of the suction cup 20 so that the side of the plate 6 is tightly attached to the pressing assembly 33.

[0090] To improve the adaptability to edge banding of different board materials 6, the rotary table 30 is rotatably mounted on the frame 1. Specifically, the rotary table 30 is a flat circular plate with several arc-shaped holes. The arc value at both ends of the arc-shaped holes is 15°. The rotary table 30 can be rotated to adjust the edge banding direction to adapt to the edge banding requirements of board materials 6 with different shapes.

[0091] Based on the above specific implementation methods, please refer to Figure 4 The tape feeding assembly 31 includes a guide wheel 310, an encoding wheel 311, a tape pressing cylinder 312, a tape feeding wheel 313, a cutting knife 314, a guide plate 315, an adhesive application shaft 316, and a tape pressing wheel 317 arranged sequentially along the tape conveying direction.

[0092] The guide wheel 310 and the belt feeding wheel 313 are both two in number. The two guide wheels 310 are spaced apart, and the two belt feeding wheels 313 are spaced apart. A channel for conveying the edge sealing tape is formed between the two guide wheels 310 and the two belt feeding wheels 313. The encoder wheel 311, the belt pressing cylinder 312, the belt guide plate 315 and the belt pressing wheel 317 are located on the first side of the channel. The glue application shaft 316 is located on the second side of the channel. An encoder is also provided on the second side of the channel. The encoder is opposite to the encoder wheel 311. The cutting knife 314 has a cutting opening for the edge sealing tape to pass through. The glue application assembly 32 is used to apply glue to the glue application shaft 316. The glue application shaft 316 is arranged opposite to the belt pressing wheel 317.

[0093] Specifically, the edge banding tape passes through the gap between the two guide wheels 310 and the gap between the two feed wheels 313. When the edge banding tape passes through this gap, the encoder wheel 311 rotates, driving the encoder to calculate the length of the edge banding tape that has passed, so that the accuracy of the edge banding tape length required for subsequent processes is within 0.3mm. After the cutting blade 314 cuts the edge banding tape, the pressing cylinder 312 presses down on the edge banding tape to prevent it from moving backward, ensuring the accuracy of the calculated edge banding tape length. One of the feed wheels 313 is driven to rotate by the transmission assembly 328, which provides a certain amount of power to the edge banding tape, driving it forward. The other feed wheel 313 is connected to a cylinder. When feeding the tape, the cylinder extends and presses the edge banding tape onto the other feed wheel 313, making the edge banding tape make close contact with the feed belt, ensuring that the edge banding tape moves forward normally.

[0094] The cutting blade 314 mainly consists of a cutting tool, a cylinder, and a cutting holder. The cutting tool is connected to the output shaft of the cylinder, and the cutting tool and the cutting holder are positioned opposite each other. There is a cutting opening between the cutting tool and the cutting holder for the edge banding tape to pass through. When the edge banding tape is fed out to a preset length, the cylinder operates, quickly pushing the cutting tool out to cut the edge banding tape. The function of the guide plate 315 is to ensure that the edge banding tape can smoothly contact the glue application shaft 316, ensuring the uniformity of glue application to the edge banding tape.

[0095] The specific structure of the glue application component 32 can be found in the utility model patent with Chinese patent number CN222270653U. The glue application component 32 has the functions of quickly switching glue pots and glue and cleaning glue pots, which can solve the problems of existing edge banding machines not being able to quickly switch glue pots and glue and the inconvenience of cleaning glue pots.

[0096] Further, please refer to Figure 5 and Figure 6 The pressing assembly 33 includes a buffer cylinder 320, a laser connector 321, a bearing roller 322, a hot air cover 323, a belt feeder 324, a pressing roller 325, a pressing contour roller 326, and a tension adjustment assembly 327 arranged sequentially along the conveying direction of the sheet 6.

[0097] The output shaft of the buffer cylinder 320 is equipped with a buffer wheel;

[0098] The belt feed lever 324 is located on one side of the belt pressure roller 317, the hot air hood 323 is located in the middle of the belt feed lever 324, the hot air hood 323 is connected to the hot air gun, and the air outlet direction of the hot air hood 323 is towards the belt feed lever 324.

[0099] The tension adjustment component 327 is used to adjust the pressing force between the pressing and shaping wheel 326 and the plate 6. The tension adjustment component 327 includes a vertical rod 3270, a bracket 3271, a torsion spring 3272, a first limiting plate 3273, a second limiting plate 3274, and an adjusting screw 3275.

[0100] The first end of the bracket 3271 is provided with a pivot hole for the upright rod 3270 to pass through. One end of the upright rod 3270 is provided with a nut. The upright rod 3270 is sequentially connected and fixed to the rotary table 30 after passing through the first limiting plate 3273, the second limiting plate 3274, the torsion spring 3272, and the bracket 3271. The first end of the torsion spring 3272 is connected to the bracket 3271, and the second end of the torsion spring 3272 is connected to the first limiting plate 3273. The second limiting plate 3274 is provided with a rod body coaxial with the upright rod 3270, which engages with the bracket 3271. The pressing and shaping wheel 326 is rotatably connected to the second end of the bracket 3271 via a pivot. The pressing and shaping wheel 326 is mounted on the tension adjustment assembly 327. The torsion spring 3272 provides pre-tension to the pressing and shaping wheel 326, ensuring that the pressing and shaping wheel 326 can achieve secondary pressing and that the edge banding tape can be tightly adhered to the board 6.

[0101] The transmission assembly 328 is used to drive the belt feeder 313, the glue application shaft 316 and the pressing roller 325 to rotate synchronously.

[0102] The outer circumferences of the buffer wheel, bearing roller 322, and pressing wheel 325 together constitute the working path for edge sealing of the sheet 6. Under the action of the feeding assembly 34, the sheet 6 can automatically rotate and achieve four-sided sealing under the action of the edge sealing assembly 3. The buffer cylinder 320 and buffer wheel play a buffering role during the rotation of the sheet 6 to ensure the accuracy of the laser connector 321 during the connection. The laser connector monitors the length of the edge sealing strip to ensure that both ends of the edge sealing strip are closed, forming a closed-loop edge sealing. The laser connector 321 is equipped with a high-performance laser displacement sensor and a programmable controller to realize the automated control of the system and ensure that the length of the edge sealing strip can be accurately connected, so that the system can complete the connection within an accuracy range of ±0.3mm. Two sets of bearing rollers 322 are provided on the rotary table 30 to improve the smoothness of the movement of the sheet 6. The hot air hood 323 is connected to the hot air gun, which is powered by the mains. The air outlet of the hot air hood 323 faces the tape feeder 324. Its function is to blow hot air to soften the edge banding tape and glue, so that the edge banding tape adheres more firmly to the wooden board, especially when the temperature is low.

[0103] The edge banding assembly 3 is powered by a transmission component 328, which includes a servo motor 3500 mounted below the rotary table 30. The servo motor 3500 drives the feed pulley 313, the glue application shaft 316, and the pressing roller 325 to rotate synchronously via a sprocket and chain.

[0104] In practical applications, when the rocker arm 2 is not needed, it is difficult to adjust the overall machine to be relatively level with the ground, causing the rocker arm 2 to swing around due to its own weight, affecting its portability when used again. To solve this technical problem, based on the above-described specific implementation method, please refer to... Figures 7 to 9The aforementioned rocker arm 2 includes a lower rocker arm 21, an upper rocker arm 22, a lower limit seat 23, an upper limit seat 24, and a magnet mounting base 25. The lower rocker arm 21 is rotatably connected to the frame 1 via a rotating shaft. The first end of the upper rocker arm 22 is rotatably connected to the lower rocker arm 21 via a rotating shaft. The suction cup 20 is rotatably connected to the second end of the upper rocker arm 22 via a rotating shaft. The lower limit seat 23 and the magnet mounting base 25 are disposed on the lower rocker arm 21. The magnet mounting base 25 is disposed opposite to the frame 1, and a rubber-coated magnet is disposed inside the magnet mounting base 25. The coated magnet is magnetically connected to the frame 1. When the rocker arm 2 is not needed, the lower rocker arm 21 can be magnetically fixed to the frame 1, at which point the lower rocker arm 21 is stationary relative to the frame 1. An elastic glass bead 26 is provided inside the lower limit seat 23, and the upper limit seat 24 is located on the upper rocker arm 22. The upper limit seat 24 has a groove for the elastic glass bead 26 to fit into. When the upper rocker arm 22 is rotated, the elastic glass bead 26 in the lower limit seat 23 sinks into the spherical groove inside the upper limit seat 24, at which point the upper rocker arm 22 is stationary relative to the lower rocker arm 21. When the coated magnet in the magnet mounting base 25 is magnetically attracted to the frame 1, and the elastic glass bead 26 sinks into the groove, the rocker arm 2 is stationary relative to the frame 1, thus achieving the purpose of limiting its position. When the rocker arm 2 needs to be used, pushing the upper rocker arm 22 and the lower rocker arm 21 will release the rocker arm 2.

[0105] Further, please refer to Figures 10 to 12 as well as Figure 18 The feeding assembly 34 includes a wheel axle 340, a rotating arm 341, a fixed plate 342, a slider 343, a guide rail 344, a sliding plate 345, a connecting seat 346, a feeding cylinder 347, a feeding cylinder seat 348, a feeding wheel 349, and a drive assembly 350.

[0106] The axle 340 is fixed to the frame 1. A boss is provided on the top of the axle 340. The rotating arm 341 has an open circular hole that matches the boss. The rotating arm 341 also has a groove communicating with the open circular hole. The groove extends to the first end of the rotating arm 341. A bolt passes through the groove, and a nut is connected to the bolt. The second end of the rotating arm 341 is connected to a fixing plate 342. The fixing plate 342 has the slider 343 and a connecting rod on its side facing away from the rotating arm 341. The connecting seat 346 is provided. The slider 343 is slidably connected to the guide rail 344. The guide rail 344 is disposed on the sliding plate 345 and is perpendicular to the rotating arm 341. The feeding wheel 349 is rotatably connected to the sliding plate 345 through a rotating shaft. The driving assembly 350 is used to drive the feeding wheel 349 to rotate. The feeding cylinder seat 348 is disposed on the sliding plate 345. The feeding cylinder 347 is disposed on the cylinder seat. The output shaft of the feeding cylinder 347 is connected to the connecting seat 346.

[0107] The slider 343 is fixed to the fixed plate 342 with screws, and the guide rail 344 is fixed to the sliding plate 345 with screws. When the slider 343 and guide rail 344 are combined, the connecting seat 346, feeding cylinder 347, feeding wheel 349, and drive assembly 350 mounted on the sliding plate 345 can move up and down with the sliding plate 345, thus adapting to different thicknesses of the sheet material 6. Specifically, when the feeding cylinder 347 extends, the sliding plate 345 moves downwards; when the feeding cylinder 347 retracts, the sliding plate 345 moves upwards. The feeding wheel 349 powers the sheet material 6 to the pressing wheel 325 in the edge banding assembly 3. The pressing wheel 325 has the power to drive the wood board, thus achieving automatic feeding and saving labor.

[0108] Furthermore, the drive assembly 350 includes a servo motor 3500, a planetary reducer 3501, a drive sprocket 3502, a driven sprocket 3503, a tensioner 3504, and an adjusting sprocket 3505;

[0109] The planetary reducer 3501 is connected to the servo motor 3500. The planetary reducer 3501 is mounted on the sliding plate 345. The driving sprocket 3502 is connected to the output shaft of the plate 6 (6) of the planetary reducer 3501. The driven sprocket 3503 is connected to the rotating shaft. The driving sprocket 3502 and the driven sprocket 3503 are connected by a chain belt. The tensioning seat 3504 is mounted on the sliding plate 345 and is located between the driving sprocket 3502 and the driven sprocket 3503. The tensioning seat 3504 has a horizontal bar hole. A bearing sleeve is provided in the horizontal bar hole. The bearing sleeve is connected and fixed to the tensioning seat 3504 by bolts. A shaft is passed through the bearing sleeve. The shaft is connected to the adjusting sprocket 3505. The adjusting sprocket 3505 is engaged with the chain belt.

[0110] Further, please refer to Figures 13 to 17 The function of the air-floating edge trimming mechanism 4 is to trim off the excess edge banding tape on the top and bottom of the board 6. Its stroke is an arc to ensure that the edge banding tape is flush with the edge of the board 6. The edge trimming assembly 40 also includes a motor base 403, an edge trimming dust hood 404, an adjustment plate 405, a first support plate 406, a photoelectric base 407, a first adjustment handle 408, a first linear bearing, a second support plate 410, an edge trimming cylinder 411, an edge trimming cylinder base 412, a second adjustment handle 413, and a fixed base 414.

[0111] The trimming motor 400 passes through the motor base 403 and is fixed to the motor base 403 by screws. The motor shaft of the trimming motor 400 is exposed in the motor base 403 and connected to the trimming blade 402. The trimming dust hood 404 is provided on the end face of the motor base 403 facing the trimming blade 402. The trimming dust hood 404 has a notch to avoid the trimming blade 402 and the air float column 401.

[0112] The motor mount 403 has opposing first and second sides;

[0113] The adjusting plate 405 is fixed on the trimming motor 400 and located on the first side of the motor base 403. The first support plate 406 is disposed on the first side of the motor base 403. The photoelectric base 407 is disposed on the first support plate 406. The bottom of the first support plate 406 is connected to the air float column 401. The adjusting plate 405 is provided with a threaded hole for the first adjusting handle 408 to be screwed in. The first adjusting handle 408 passes through the adjusting plate 405 and is threadedly connected to the first support plate 406.

[0114] The motor base 403 is vertically provided with a first linear bearing, and a first optical axis 409 is provided inside the first linear bearing. The top of the first optical axis 409 is connected to a second support plate 410. The trimming cylinder seat 412 is provided on the motor base 403, and the trimming cylinder seat 412 is provided with a notch to avoid the first optical axis 409. The trimming cylinder 411 is provided on the trimming cylinder seat 412, and the output shaft of the trimming cylinder 411 is connected to the second support plate 410. The second adjusting handle 413 is threadedly connected to the second support plate 410, and the end of the second adjusting handle 413 is opposite to the trimming cylinder 411. The end of the first optical axis 409 is connected to a fixing seat 414, and the fixing seat 414 is fixed on the frame 1.

[0115] Specifically, the air-bearing column 401 is bolted to the first support plate 406. The air-bearing column 401 has a connector for airflow; when air is blown in, it forms an air layer on the surface of the sheet material 6, thus fixing the sheet material 6 in place. Rotating the first adjusting handle 408 adjusts the height of the air-bearing column 401 to match the cutting edge height of the trimming blade 402. At this point, the sheet material 6 can be pressed tightly against the surface of the air-bearing column 401 to achieve the desired trimming. Both trimming components 40 are equipped with trimming cylinders 411. The trimming cylinders 411 extend and retract, driving their respective trimming components 40 to move up and down, adapting to sheet materials 6 of different thicknesses. When switching to sheet materials of other thicknesses, rotating the height of the second adjusting handle 413 limits the trimming blade 402 to a preset height.

[0116] The two trimming components 40 are an upper trimming component 40 and a lower trimming component 40. The lower trimming component 40 is also provided with a spring 415. The spring 415 is sleeved on the first optical shaft 409, and the two ends of the spring 415 abut against the second support plate 410 and the trimming cylinder seat 412, respectively. The overall structure of the two trimming components 40 is basically the same. The difference between the upper trimming component 40 and the lower trimming component 40 is that the lower trimming component 40 is equipped with a spring 415. The spring 415 provides an upward elastic force to the lower trimming component 40, so that the lower trimming component 40 can press the plate 6 tightly, while the upper trimming component 40 achieves the pressing of the plate 6 by its own gravity.

[0117] In addition, the upper trimming assembly 40 and the lower trimming assembly 40 can share the first optical axis 409, the middle part of which is located in the fixing seat 414 and is fixed by bolt clamping.

[0118] Furthermore, the fixing base 414 includes a base 414a and a mounting plate 414b, wherein the mounting plate 414b is fixed on the base 414a and the optical axis is fixed on the mounting plate 414b;

[0119] The air flotation trimming mechanism 4 also includes a power assembly 42, which includes a motor plate 420, a reduction motor 421, a drive pulley 422, a synchronous belt 423, a pressure plate 424, an upper clamping plate 425, a contour wheel seat 426, a driven pulley 427, and a lower clamping plate 428.

[0120] The motor plate 420 is mounted on the base 414a, and the reduction motor 421 is mounted on the motor plate 420. The output shaft of the reduction motor 421 is connected to the drive pulley 422. The contour wheel seat 426 is provided with a circular hole for the optical axis of the first linear bearing to pass through. The contour wheel seat 426 is fixed on the mounting plate 414b. The pressure plate 424, the upper clamping plate 425, and the lower clamping plate 428 are sequentially stacked on the top end face of the contour wheel seat 426. The first end of the upper clamping plate 425 is located between the two trimming blades 402, and the first end of the upper clamping plate 425 is rotatably provided with a driven pulley 427. The drive pulley 422 and the driven pulley 427 are meshed and connected by a synchronous belt 423.

[0121] Specifically, the motor plate 420 is provided with several optical shafts, which support the geared motor 421, allowing the output shaft of the geared motor 421 to be suspended in the air, thereby ensuring that the driving pulley 422 and the driven pulley 427 are on the same horizontal plane. The contour wheel seat 426 is fixed to the base 414a through two optical shafts. A pad is installed between the upper clamping plate 425 and the lower clamping plate 428. The lower clamping plate 428 is mounted and fixed to the contour wheel seat 426 via the pad. One end of the upper clamping plate 425 has a cylinder protruding towards the lower clamping plate 428. This cylinder is used to mount the driven pulley 427. The cylinder is coaxial with the trimming blade 402. The driving pulley 422 and the driven pulley 427 are connected by a synchronous belt 423. The geared motor 421 drives the synchronous belt 422. The timing belt 423 drives the plate 6, and its outer periphery contacts the plate 6, providing the plate 6 with the power to move, allowing the plate 6 to be trimmed at a uniform speed. The pressure plate 424, located above the upper clamping plate 425, limits the timing belt 423 to prevent it from falling off. The diameter of the timing belt 423 after it is enclosed by the cylinder is the same as the cutting edge diameter of the trimming knife 402. When the plate 6 is close to the timing belt 423, it ensures that a relatively ideal arc can be trimmed. Its working state can be found in [reference needed]. Figure 19 .

[0122] Alternatively, the timing belt 423 can be replaced with a flat belt or a V-belt.

[0123] Furthermore, the air flotation trimming mechanism 4 also includes a flat scraper assembly 43, which includes a connecting plate 430, a second linear bearing 431, a flat scraper cylinder 432, a flat scraper slide 433, a flat scraper shaft 434, and a flat scraper blade 435. The second linear bearing 431 is vertically mounted on the flat scraper slide 433, and the flat scraper shaft 434 passes through the second linear bearing 431. The top of the flat scraper shaft 434 is connected to the connecting plate 430, and the bottom of the flat scraper shaft 434 is connected to the flat scraper blade 435. The top of the flat scraper slide 433 is provided with a groove for accommodating the flat scraper cylinder 432, and the output shaft of the flat scraper cylinder 432 is connected to the connecting plate 430. The flat scraper blade 435 is used to scrape off residual edge banding tape and glue after trimming. The flat scraper cylinder 432 is installed in the groove of the flat scraper slide 433, which can reduce the volume of the flat scraper assembly 43. In use, the flat scraper 435 moves up and down by extending and retracting the flat scraper cylinder 432, thereby adapting to different thicknesses of the board 6.

[0124] The workflow for this irregular edge banding is as follows: First, the operator places the irregularly shaped sheet 6 on the suction cup 20 above the rocker arm 2. By pressing the foot switch, the suction cup 20 is activated, thus securing the sheet 6. Then, the operator manually moves the sheet 6 to the edge banding assembly 3 area. After pressing the edge banding switch on the foot switch, the edge banding assembly 3 begins edge banding the sheet 6. The feeding component 34 can be activated by clicking on the CNC display device 5. When edge banding, the feeding component 34 descends, and the feeding wheel 349 presses down on the sheet 6. At this point, the operator can release the hand for automatic edge banding. After edge banding the sheet 6, the operator rotates the rocker arm 2 to move the sheet 6 to the air-float trimming mechanism 4, and then presses the trimming foot switch to perform trimming.

[0125] As can be seen from the above, the irregular edge banding machine provided by this utility model has various mechanisms working closely together to complete the edge banding. The strong suction cup 20 adsorbs the board 6, ensuring smooth and efficient edge banding. The foot pedal controls the opening of the suction cup 20 and the feeding of the edge banding tape, making operation simple and convenient. The edge banding assembly 3 is compatible with both hot glue and dual-color PUR glue pots, and features a quick-change mechanism for easy operation. Auxiliary hot air softens the edge banding tape, improving the adhesion strength and tightness between the edge banding tape and the board. The feeding component 34 automatically feeds the board for edge banding, with adaptive thickness of the board 6, resulting in high production efficiency. After applying glue, the edge banding strip is pressed firmly to the board 6 twice, ensuring a strong bond. The laser in the edge banding assembly 3 automatically identifies the remaining length of the board 6 to be edge banded, with a docking error of 0.3mm, ensuring precise docking. The trimming mechanism is easy to operate, smoothing out any excess tape on the top and bottom of the edge banding strip.
