Description

Technical Field

[0001] This invention relates to the field of edge banding machine technology, and specifically to an edge banding machine for woodworking boards. Background Technology

[0002] During the processing of woodworking boards, the edges of the boards need to be sealed to enhance durability and aesthetics. There are three traditional methods for sealing board edges: manual sealing, edge sealing using large machine tools, and edge sealing using small edge sealing machines.

[0003] Manual edge banding involves manually applying glue, pasting, and cutting to seal the edges of boards. It has advantages such as simple operation and low cost; however, it is less efficient and has limited precision, resulting in poor edge banding quality and problems such as glue bursting, peeling, and detachment.

[0004] Large-scale edge banding typically employs large-scale edge banding machines. After the operator feeds the sheet material into the machine, multiple robotic arms work together to cut, bond, and shape the material, completing the edge banding operation. Large-scale edge banding machines offer advantages such as high production efficiency and excellent edge banding results. However, large-scale edge banding machines are often bulky, requiring a certain amount of space, and have specific requirements regarding the size and shape of the processed sheet material. Furthermore, due to their complex structure, maintenance is relatively difficult.

[0005] Small edge banding machines are generally suitable for smaller and thicker boards, making them ideal for small- to medium-scale production or individual DIY projects. They are easy to operate, have a simple structure, and produce good processing results. With technological advancements, small edge banding machines can perform more and more functions, further improving processing efficiency. They have gradually become the preferred edge banding equipment for woodworking boards, making them the most widely used equipment for edge banding of boards.

[0006] The following example is taken from a small woodworking board processing plant. In such plants, edge banding is frequently required for custom-made boards, including not only the most common rectangular boards but also irregularly shaped boards such as round boards. However, existing edge banding machines for small woodworking boards cannot fully adhere to the surface of irregularly shaped boards, resulting in problems such as edge lifting and unevenness, affecting the quality and reducing production efficiency. To address these issues, Jiaxing Aimi Decoration Materials Co., Ltd. invented an irregularly shaped edge banding machine (application number: CN202222109198.X, announcement date: 2022-12-23). ​​This invention includes: a placement board, with a placement rod fixedly connected to its top surface, and an automatic suction cup on the top surface of the placement board; and a hot melt adhesive spraying machine fixedly connected to the top surface of the placement board. A positioning post is fixedly connected to the top surface of the plate; a rotating assembly is set on the top surface of the plate. When the worker wraps the edge banding strip around the outside of the placing rod, when the drive shaft of the stepper motor drives the rotating shaft to rotate, the rotating shaft can drive the plate to rotate through the automatic suction cup. When the drive shaft of the servo motor drives the gear to rotate, the two gears mesh together, so that the gear can drive the extrusion rod to rotate through the limiting post, which facilitates the movement of the edge banding strip later. The positioning post can position one side of the edge banding strip, which makes it easier to push the edge banding strip to the side of the plate later, so that the edge banding strip is tightly attached to the side of the plate. However, the above invention only positions the edge banding strip on the processing surface of the irregular plate, and does not reasonably solve the problem of adapting and fitting the edge banding machine's hot press roller and other devices to irregular plates, and cannot effectively guarantee the quality and efficiency of processing.

[0007] In view of the above, in order to overcome the above technical problems, the present invention designs a woodworking board edge banding machine, which solves the above technical problems. Summary of the Invention

[0008] The technical problem to be solved by the present invention is that existing edge banding machines cannot adapt to the processing surface of irregularly shaped boards, resulting in quality problems such as edge banding lifting and unevenness.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] This invention provides a woodworking board edge banding machine, comprising a base plate, an adaptive mechanism, a material tray, a cutting device, a gluing device, a sensor, a hot press roller, a discharge device, and a support frame. The adaptive mechanism is fixedly mounted on the base plate. This adaptive mechanism automatically adjusts the working positions of the gluing device and the hot press roller when processing irregularly shaped woodworking boards, ensuring they fully conform to the processing surface, and locks the mechanism when no adjustment is needed. The material tray is fixedly mounted on the adaptive mechanism. The cutting device is fixedly mounted on the base plate and is used to convey edge banding tape and automatically cut the edge banding tape after edge banding processing. The gluing device is fixedly mounted on the base plate. In the aforementioned adaptive mechanism, the glue application device is used to adjust the glue dispensing amount according to the applied pressure, thereby uniformly applying hot melt adhesive to the processing surface of the board to be processed; the sensor is fixedly installed on the glue application device, and the sensor is used to detect the completion status of the edge banding processing and transmit a cut-off signal to the material cutting device; the hot pressure roller is fixedly installed on the adaptive mechanism; the material dispensing device is fixedly installed on the hot pressure roller, and the material dispensing device is used to flexibly adjust its working position according to the processing surface of the irregular wood board, automatically attaching the edge banding tape to the processing surface; the support frame is rotatably installed under the base plate, and the support frame is used to place and freely move the board to be processed.

[0011] Preferably, the adaptive mechanism includes a sliding device, a locking adjustment device, a support element, a support plate, and a flexible element. The sliding device is bolted to the base plate and can drive the support plate to rotate around its center at a rotation angle of 45°. The locking adjustment device is welded to the sliding device and can lock the movement of the sliding device when the adaptive mechanism does not need to be adjusted. One end of the support element is welded to the sliding device, and the other end is fixedly mounted to the support plate. The support element uses two Festo DNC-32-50-PPV-A small pneumatic rods with a diameter of 32 mm, a stroke of 50 mm, and a maximum load capacity of 520 N. It employs a built-in cylinder and piston rod design to provide stable power output. The flexible element is fixedly mounted on the support plate, which is an aluminum alloy arc plate with a radius of 640 mm, an arc length of 330 mm, and a thickness of 10 mm.

[0012] Preferably, the sliding device includes an arc-shaped guide rail and an arc-shaped slider. The arc-shaped guide rail is bolted and fixedly installed on the base plate. Symmetrical 40×10 mm limit frames are provided at both ends of the arc-shaped guide rail. Three 30×30 mm rectangular through holes are arrayed on the arc-shaped guide rail. The arc-shaped guide rail is made of 6061 aluminum alloy, which has good processing performance. The arc-shaped slider is slidably installed on the arc-shaped guide rail. The arc-shaped slider is made of the same 6061 aluminum alloy as the arc-shaped guide rail. Because the locking adjustment device is welded and fixed on the arc-shaped slider, the material of the slider must have good weldability. Therefore, the arc-shaped slider can be made of 6061 aluminum alloy, which has good weldability. The arc-shaped slider and the arc-shaped guide rail are coaxially aligned. The arc length of the arc-shaped guide rail is 480 mm, and the arc length of the arc-shaped slider is 240 mm, meaning the arc length of the arc-shaped slider is half the arc length of the arc-shaped guide rail.

[0013] Preferably, the locking adjustment device includes a handle, a lead screw, a fixing block, and a fixing frame. The lead screw has a diameter of 20 mm, a length of 50 mm, and a thread height of 20 mm. The lead screw is made of 40Cr alloy steel, which has high strength and corrosion resistance, ensuring high precision and long service life. The handle is welded and fixedly mounted to one end of the lead screw. The handle is a circular block with a radius of 40 mm. Ten semi-circular grooves with a radius of 7 mm are arranged around the center of the handle to increase friction and facilitate rotation of the lead screw. The fixing block is rotatably mounted to the other end of the lead screw. The fixing block is a rectangular block of 30×30×20 mm. The fixing frame is welded and fixedly installed on the sliding device. The fixing frame has a threaded hole to accommodate the movement of the lead screw. A rectangular through hole of 30×30 mm is opened in the center of the fixing frame. The lead screw is rotatably installed in the fixing frame. When it is necessary to fix the adaptive mechanism, the handle is turned to drive the lead screw to rotate. Through the cooperation between the thread on the lead screw and the threaded hole on the fixing frame, the fixing block is pushed forward and is just locked in the rectangular through hole of the fixing frame and the arc-shaped guide rail, preventing the arc-shaped slider from sliding on the arc-shaped guide rail, thus completing the locking of the sliding device.

[0014] Preferably, the flexible element includes a first connecting rod, a second connecting rod, a ball joint, a pneumatic rod, and a spring. One end of the first connecting rod is fixedly mounted on the support plate. The first connecting rod is a rectangular rod of 30×25×100 mm, with a 20×20×100 mm rectangular groove inside. The first connecting rod is made of 304 stainless steel, which has the advantages of corrosion resistance, high cost-effectiveness, and sufficient load capacity. The other end of the first connecting rod is hinged to the second connecting rod, which is 20×20×150 mm in size. The first connecting rod is a rectangular rod with a diameter of 40 mm. The free end of the second connecting rod has a spherical groove with a diameter of 40 mm. The second connecting rod is made of the aforementioned 304 stainless steel. A ball shaft with a diameter of 40 mm is rotatably mounted on the free end of the second connecting rod, fitting perfectly within the spherical groove on the free end of the second connecting rod. The ball shaft is also made of the aforementioned 304 stainless steel. One end of the pneumatic rod is fixedly mounted on the first connecting rod, and the other end is fixedly mounted on the second connecting rod. The pneumatic rod is an SMC MHZL10-30-X1 pneumatic rod with a diameter of 10 mm and a length of 30 mm. The piston rod is made of stainless steel. This pneumatic rod is pneumatically driven and has advantages such as fast response, smooth operation, and long service life. One end of the spring is welded and fixedly mounted on the first connecting rod, and the other end is welded and fixedly mounted on the second connecting rod. The pneumatic rod is installed inside the spring.

[0015] Preferably, the material cutting device includes a base, a coil element, a power supply element, a power element, a rotating block, a cutting element, and a transmission element. The base is a trapezoidal boss, and the base is welded and fixedly mounted on the base plate. The coil element is rotatably mounted on the base. The coil element consists of two metal cylinders with a diameter of 20 mm and rotating in opposite directions. The coil element is made of the aforementioned 304 stainless steel material. The power supply element is fixedly mounted on the base. The power supply element consists of two miniature DC motors, one of which drives the coil element to rotate, and the other is connected to the sensor to drive the power element to rotate. The power supply element is a 100:1 miniature DC motor. The power element is rotatably mounted on the base plate. On the base, the power element consists of two circular bosses with a diameter of 10 mm and a height of 5 mm; the rotating block is rotatably mounted on the power element; the cutting element is rotatably mounted on the rotating block, and the cutting element uses two guillotines with a width of 6 mm; the transmission element is slidably mounted on the cutting element, and the transmission element can be a guide rail. The transmission element drives the cutting element to move together. The rotating material element rotates to convey the edge sealing tape into the cutting element. When the sensor transmits a cutting signal to the power supply element, the power supply element drives the power element to rotate. Through the cooperation of the rotating block and the transmission element, the cutting element is driven to move together to cut and sever the edge sealing tape.

[0016] Preferably, the glue application device includes a connecting plate, a support rod, an elastic element, a glue application plate, and a glue storage box. The connecting plate is fixedly mounted on the adaptive mechanism; one end of the support rod is fixedly mounted on the connecting plate; the other end of the support rod is fixedly mounted with the elastic element, which can be a small spring with a diameter of 3 mm; the glue application plate is fixedly mounted on the elastic element, and the glue application plate is an arc-shaped thin plate made of PVC material; the glue storage box is fixedly mounted on the connecting plate, and the glue storage box is installed directly above the glue application plate. The bottom of the glue storage box is a ramp with an inclination of 15°. A lower glue groove is opened at the front end of the lower part of the glue storage box. When the glue coating plate is squeezed, the elastic element and the support rod work together to drive the glue coating plate to move backward. The hot melt glue in the glue storage box flows from the lower glue groove to the surface of the glue coating plate under the influence of gravity. When the glue coating plate is not squeezed, the glue coating plate returns to its initial position, which blocks the lower glue groove. The hot melt glue stops flowing, reducing the loss of hot melt glue, reducing production costs, and also reducing contamination to other mechanisms.

[0017] Preferably, the hot press roller includes a fixing element, a heat-conducting element, and a hot pressing element. The fixing element is welded and fixedly mounted on the adaptive mechanism. The heat-conducting element is fixedly mounted on the fixing element by welding, and a heating wire is installed inside the heat-conducting element. The hot pressing element is rotatably mounted on the heat-conducting element, and the hot pressing element wraps around the heat-conducting element. Since the heat-conducting element needs to be heated and the temperature is relatively high, the hot pressing element is a silicone rubber cylinder with a diameter of 50 mm. Silicone rubber has excellent wear resistance and high temperature resistance, and low hardness, which can better fit the processing surface when performing edge sealing processing on irregularly shaped plates, and press the edge sealing tape tightly.

[0018] Preferably, the discharge device includes a discharge channel, an elastic alloy, and a pressure plate. The discharge channel is an arc-shaped channel with a length of 70 mm. The elastic alloy is fixedly installed on the discharge channel by bolts. The elastic alloy is made of nickel-based alloy material and is an arc-shaped alloy plate with a thickness of 1 mm, which has good elasticity and corrosion resistance. The pressure plate is rotatably installed on the discharge channel, and the elastic alloy is fixedly installed between the discharge channel and the pressure plate. When processing irregularly shaped plates, the pressure plate can appropriately change its working angle according to the surface shape of the plate. After processing is completed, the elastic alloy restores its shape, driving the pressure plate back to its initial working position.

[0019] Preferably, the support rack includes a first swing arm, a second swing arm, a base, and a suction cup. The first swing arm is rotatably mounted under the base plate via a pin connection. The first swing arm is 200 mm long and made of lightweight BMT-SSG-500 aluminum alloy, making it easy to handle and install. It has a diameter of 12 mm. The second swing arm is hinged to the free end of the first swing arm. The second swing arm is also made of the aforementioned BMT-SSG-500 aluminum alloy and is 300 mm long. The other end of the second swing arm is rotatably mounted to the base. The base has a diameter of 160 mm and is made of 6061-T6 aluminum alloy. The base is lightweight, high-strength, and easy to process and form, making it suitable for supporting different boards in edge banding machines. The suction cup is fixedly mounted on the base. The suction cup is made of neoprene rubber with a diameter of 80 mm and is suitable for adsorbing smooth wood surfaces.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. A woodworking board edge banding machine of the present invention, by designing the adaptive mechanism, automatically and flexibly adjusts the working position of the gluing device and the hot pressure roller according to the irregular processing surface of the irregular board, so that they completely fit the processing surface of the board to be processed; by designing the sliding device in the adaptive mechanism, the angle of the gluing device and the hot pressure roller is adjusted in time according to the pressure feedback during processing, which can realize flexible processing of boards of different sizes. At the same time, by designing the flexible element in the adaptive mechanism, automatic edge banding processing can also be achieved for boards of different thicknesses.

[0022] 2. A woodworking board edge banding machine of the present invention, by designing the glue application device, the glue application board moves back and forth according to the pressure feedback, thereby controlling the glue dispensing amount of the glue storage box; after the edge banding process is completed, the glue application board can automatically return to its original position, preventing the glue storage box from continuing to dispense glue, reducing the waste of hot melt glue and the contamination of the internal structure.

[0023] 3. The wood panel edge banding machine of the present invention, by designing the hot press roller, the hot press element can actively adjust its working position according to the size of the panel processing surface, and the hot press element can slide freely on the heat conduction element. Therefore, when the panel processing contour changes suddenly, it can also follow and fit the processing surface well, so as to achieve the pressing and compaction of the edge banding.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] Example 1: As Figure 1 As shown, a woodworking board edge banding machine includes a base plate 1, an adaptive mechanism 2, a material support tray 3, a material cutting device 4, a glue application device 5, a sensor 6, a hot press roller 7, a discharge device 8, and a support frame 9. The base plate 1 is fixedly installed on any working plane. The adaptive mechanism 2 is fixedly installed on the base plate 1. The material support tray 3 is fixedly installed on the adaptive mechanism 2. The material cutting device 4 is fixedly installed on the base plate 1. The glue application device 5 is fixedly installed on the adaptive mechanism 2. The sensor 6 is fixedly installed on the glue application device 5. The hot press roller 7 is fixedly installed on the adaptive mechanism 2. The discharge device 8 is fixedly installed on the hot press roller 7. The support frame 9 is rotatably installed under the base plate 1.

[0038] The adaptive mechanism 2 is bolted to the base plate 1. When processing irregularly shaped wood panels, the adaptive mechanism 2 automatically adjusts the working positions of the gluing device 5 and the hot press roller 7 to ensure complete contact with the processing surface. It also locks the mechanism when no adjustment is needed. The material tray 3 is welded to the adaptive mechanism 2 and is used to hold the edge banding tape. The cutting device 4 is welded to the base plate 1 and is used to convey the edge banding tape and automatically cut it after edge banding processing. The gluing device 5 is welded to the base plate 1. On the adaptive mechanism 2, the glue application device 5 is used to evenly apply hot melt adhesive to the processing surface of the board to be processed according to the pressure applied. The sensor 6 is fixedly installed on the glue application device 5 by screws and nuts. The sensor 6 is used to detect the completion status of the edge banding process and transmit a cut-off signal to the material cutting device 4. The hot pressure roller 7 is welded and fixedly installed on the adaptive mechanism 2. The hot pressure roller 7 is used to press and compact the edge banding tape attached to the surface of the board. The support frame 9 is rotatably installed below the base plate 1 by a pin shaft. The support frame 9 is used to place the board and move freely in the horizontal direction.

[0039] While existing edge banding machines are easy to operate and can position the edge banding strip on the surface of irregularly shaped boards, they cannot achieve complete adhesion for irregularly shaped boards. Furthermore, most of the internal components are fixed, making it impossible to adjust the processing angle and position for irregularly shaped boards of different sizes and thicknesses. This lack of flexibility, especially when processing a single board, can lead to edge banding warping due to sudden changes in the surface contour. In small board processing plants, this often results in increased processing costs or substandard quality. Therefore, the woodworking board edge banding machine designed in this invention automatically moves and adjusts the working position and angle of the hot pressure roller 7 and other components based on pressure feedback, enabling flexible adjustment of the edge banding machine and ensuring complete adhesion to the surface of irregularly shaped boards during edge banding.

[0040] like Figure 2As shown, the adaptive mechanism 2 includes a sliding device 21, a locking adjustment device 22, a support element 23, a support plate 24, and a flexible element 25. The sliding device 21 is bolted and fixedly installed on the base plate 1. The sliding device 21 can drive the adaptive mechanism 2 to rotate around the center of the sliding device 21, with a rotation angle of 45°. The locking adjustment device 22 is welded and fixedly installed on the sliding device 21. The locking adjustment device 22 can lock the movement of the sliding device 21 when the working position of the adaptive mechanism 2 does not need to be adjusted. One end of the support element 23 is welded and fixedly installed on the sliding device 21, and the other end of the support element 23 is fixedly installed on the support plate 24. The support element 23 uses two Festo DNC-32-50-PPV-A small pneumatic rods. The flexible element 25 is fixedly installed on the support plate 24. The support plate 24 is an aluminum alloy arc plate with a radius of 640 mm and an arc length of 330 mm. The thickness of the support plate 24 is 10 mm. Figure 3 As shown, the sliding device 21 includes an arc-shaped guide rail 211 and an arc-shaped slider 212. The arc-shaped guide rail 211 is fixedly installed on the base plate 1 by bolts. Symmetrical limit frames of 40×10 mm are provided at both ends of the arc-shaped guide rail 211. Three rectangular through holes of 30×30 mm are arranged in an array on the arc-shaped guide rail 211. The arc-shaped guide rail 211 is made of 6061 aluminum alloy, which has good machinability. The arc-shaped slider 212 is slidably installed on the arc-shaped guide rail 211. The arc-shaped slider 212 is made of... The curved guide rail 211 is made of the same 6061 aluminum alloy. Because the locking adjustment device 22 is welded and fixed to the curved slider 212, the material of the slider must have good weldability. Therefore, the curved slider 212 can be made of 6061 aluminum alloy, which has good weldability. The curved slider 212 and the curved guide rail 211 are coaxially aligned. The arc length of the curved guide rail 211 is 480 mm, and the arc length of the curved slider 212 is 240 mm, meaning the arc length of the curved slider 212 is half the arc length of the curved guide rail 211. Figure 4As shown, the locking adjustment device 22 includes a handle 221, a lead screw 222, a fixing block 223, and a fixing frame 224. The lead screw 222 has a diameter of 20 mm and a length of 50 mm. The thread length of the lead screw 222 is 20 mm. The lead screw 222 is made of 40Cr alloy steel, which has high strength and corrosion resistance, ensuring high precision and long service life. The handle 221 is welded and fixedly installed at one end of the lead screw 222. The handle 221 is a circular block with a radius of 40 mm. Ten semi-circular grooves with a radius of 7 mm are arranged around the center of the handle 221 to increase the friction of the handle 221 surface and facilitate the rotation of the lead screw 222. The fixing block 223 is rotatably installed at the other end of the lead screw 222. The fixing block 223 is a rectangular block of 30×30×20 mm. The fixing frame 224 is welded and fixedly installed on the sliding device 21. The fixing frame 224 has a threaded hole to accommodate the movement of the lead screw 222. A rectangular through hole of 30×30 mm is opened in the center of the fixing frame 224. The lead screw 222 is rotatably installed in the fixing frame 224. When it is necessary to fix the sliding device 21, the handle 221 is rotated to drive the lead screw 222 to rotate. Through the engagement of the thread on the lead screw 222 and the threaded hole on the fixing frame 224, the fixing block 223 is pushed forward and fits into the rectangular through hole of the fixing frame 224 and the arc-shaped guide rail 211, preventing the arc-shaped slider 212 from sliding on the arc-shaped guide rail 211, thus locking the sliding device 21. Figure 5As shown, the flexible element 25 includes a first connecting rod 251, a second connecting rod 252, a ball joint 253, a pneumatic rod 254, and a spring 255. One end of the first connecting rod 251 is fixedly mounted on the support plate 24. The first connecting rod 251 is a rectangular rod of 30×25×100 mm, and has a 20×20×100 mm rectangular groove inside. The first connecting rod 251 is made of 304 stainless steel, which has the advantages of corrosion resistance, high cost performance, and sufficient load capacity. The other end of the first connecting rod 251 is hinged to the second connecting rod 252, which is 20×20×... A 150 mm rectangular rod has a 40 mm diameter spherical groove at its free end, which is made of 304 stainless steel. A ball shaft 253, also 40 mm in diameter, is fixedly mounted on the free end of the second connecting rod 252, allowing it to rotate freely within the spherical groove. The ball shaft 253 is also made of 304 stainless steel. One end of a pneumatic rod 254 is fixedly mounted on the first connecting rod 251, and the other end is fixedly mounted on the second connecting rod 252. The pneumatic rod 254 is an SMC MHZL10-30-X1 pneumatic rod. One end of a spring 255 is welded and fixedly mounted on the first connecting rod 251, and the other end is welded and fixedly mounted on the second connecting rod 252. The pneumatic rod 254 is installed within the spring 255.

[0041] When the flexible element 25 is subjected to frontal pressure, the pneumatic rod 254 compresses, changing the working position of the adhesive applicator 5 and the hot press roller 7 to adapt to the irregular processing surface of the profiled sheet. When the frontal pressure disappears, the spring 255 pushes the flexible element 25 back to its original position, causing the adhesive applicator 5 and the hot press roller 7 to return to their initial working positions. When the flexible element 25 is subjected to lateral pressure, it moves the support plate 24, which, in conjunction with the support element 23, causes the arc-shaped slider 212 to slide on the arc-shaped guide rail 211, thereby changing the working position of the adhesive applicator 5. In addition to the working angle of the hot press roller 7, the rotation of the ball shaft 253 on the flexible element 25 can also slightly change the working angle of the glue applicator 5 and the hot press roller 7, so that they can better fit the irregular surface. When processing plates with regular contours, it is sometimes necessary to fix the position of the sliding device 21. At this time, the operator rotates the handle 221 on the locking adjustment device 22, and through the engagement of the screw 222 and the threaded hole on the fixing frame 224, the fixing block 223 is pushed into the rectangular through hole of the sliding device 21, locking the movement of the sliding device 21 and realizing the locking of the position of the sliding device 21.

[0042] In existing edge banding machines, the internal working components are basically fixed and locked, preventing relative displacement. This results in insufficient flexibility when processing irregularly shaped panels, often requiring manual adjustment of the panel placement angle, which frequently leads to uneven edge banding. In contrast, this invention utilizes the adaptive mechanism 2 to allow the glue applicator 5 and the hot press roller 7 to move freely. Through the cooperation of the sliding device 21 and the flexible element 25, the glue applicator 5 and the hot press roller 7 can flexibly change their working position and angle according to the direction of force, better conforming to the irregular processing surface of irregularly shaped panels. After processing, they automatically return to their initial processing position, and can be locked in place when the adaptive mechanism 2 is not needed. This design is suitable for edge banding processing of various types of panels.

[0043] like Figure 6 As shown, the material cutting device 4 includes a base 41, a coil element 42, a power supply element 43, a power element 44, a rotating block 45, a cutting element 46, and a transmission element 47. The base 41 is a trapezoidal boss, and the base 41 is welded and fixedly installed on the base plate 1. The coil element 42 is rotatably mounted on the base 41. The coil element 42 consists of two metal cylindrical tubes with a diameter of 20 mm and rotating in opposite directions. The coil element 42 is made of the aforementioned 304 stainless steel material. The power supply element 43 is fixedly mounted on the base 41. The power supply element 43 consists of two miniature DC motors, one of which drives the coil element 42. One component rotates, and another component connected to the sensor 6 drives the power element 44 to rotate. The power supply element 43 uses a 100:1 micro DC motor. The power element 44 is rotatably mounted on the base 41. The power element 44 consists of two circular bosses with a diameter of 10 mm and a height of 5 mm. The rotating block 45 is rotatably mounted on the power element 44. The cutting element 46 is rotatably mounted on the rotating block 45. The cutting element 46 uses two guillotines with a width of 6 mm. The transmission element 47 is slidably mounted on the cutting element 46. The transmission element 47 can be a guide rail, which drives the cutting element 46 to move together.

[0044] The rotating material element 42 conveys the edge sealing tape into the cutting element 46. When the sensor 6 transmits a cutting signal to the power supply element 43, the power supply element 43 drives the power element 44 to rotate. Through the cooperation of the rotating block 45 and the transmission element 47, the cutting element 46 is driven to move together to cut the edge sealing tape.

[0045] In existing edge banding machines, manual cutting is often used when conveying edge banding tape. This can easily lead to incomplete or repeated edge banding when processing irregularly shaped boards, seriously affecting the quality of edge banding. Therefore, the cutting device 4 designed in this invention, in cooperation with the sensor 6, immediately transmits a cutting signal to the power supply element 43 after detecting that the edge banding tape has completely wrapped the processed board, realizing the cutting of the material by the cutting blade. At the same time, it eliminates the need for manual trimming of the processed board afterward, improving the working efficiency of small board processing plants.

[0046] like Figure 7 As shown, the glue application device 5 includes a connecting plate 51, a support rod 52, an elastic element 53, a glue application plate 54, and a glue storage box 55. The connecting plate 51 is welded and fixedly installed on the adaptive mechanism 2. The connecting plate 51 is made of 80×40×10 mm aluminum alloy plate. One end of the support rod 52 is fixedly installed on the connecting plate 51. The support rod 52 is made of 3×3×35 mm aluminum alloy rod. The other end of the support rod 52 is fixedly installed with the elastic element 53. The elastic element 53 can... A small spring 255 with a diameter of 3 mm is used. The glue-coating plate 54 is fixedly installed on the elastic element 53. The glue-coating plate 54 is an arc-shaped thin plate made of PVC material. The glue storage box 55 is fixedly installed on the connecting plate 51 and is installed directly above the glue-coating plate 54. The bottom of the glue storage box 55 is a ramp with an inclination of 15°. The lower front part of the glue storage box 55 has a lower glue groove. The outline of the lower glue groove of the glue storage box 55 is consistent with the outline of the upper surface of the glue-coating plate 54.

[0047] When the coating plate 54 is subjected to pressure, the elastic element 53 and the support rod 52 work together to move the coating plate 54 backward. The hot melt adhesive in the glue storage box 55 flows from the lower glue groove to the surface of the coating plate 54 under the influence of gravity. When the coating plate 54 is not subjected to pressure, the coating plate 54 returns to its initial position, which blocks the lower glue groove and the hot melt adhesive stops flowing.

[0048] Existing edge banding machines generally use glue-applying rollers, with fixed glue output and speed. Besides easily wasting hot melt adhesive, excess adhesive can contaminate other parts as it's processed. Furthermore, once the hot melt adhesive cools and solidifies, it can cause machine malfunctions, requiring timely cleaning and increasing maintenance costs. The glue-applying device 5 designed in this invention automatically adjusts the glue output based on the applied pressure. Once the edge banding process is complete, the glue-applying plate 54 is no longer under pressure, and glue output automatically stops, reducing hot melt adhesive waste and contamination of other parts, thus lowering production costs.

[0049] like Figure 8As shown, the hot press roller 7 includes a fixing element 71, a heat-conducting element 72, and a hot press element 73. The fixing element 71 is welded and fixedly installed on the adaptive mechanism 2. The heat-conducting element 72 is welded and fixedly installed on the fixing element 71. The heat-conducting element 72 is a hollow aluminum tube with a diameter of 30 mm and a height of 100 mm. The heat-conducting element 72 has good thermal conductivity. A heat-conducting wire is installed inside the heat-conducting element 72. The hot press element 73 is rotatably installed on the heat-conducting element 72. The hot press element 73 wraps around the heat-conducting element 72. Since the heat-conducting element 72 needs to be heated to a high temperature, the hot press element 73 is a hollow cylinder of silicone rubber with a thickness of 20 mm and a height of 80 mm. Silicone rubber has excellent wear resistance and high temperature resistance, and low hardness. When performing edge sealing processing on irregularly shaped plates, it can better fit the processing surface and press the edge sealing tape tightly.

[0050] When the hot press roller 7 is working, the resistance wire inside the heat-conducting element 72 heats the heat-conducting element 72 to 120℃-200℃. The heat-conducting element 72 transfers heat to the hot press element 73. While the hot press element 73 rotates around the heat-conducting element 72, it presses and compacts the edge banding tape attached to the surface of the board. When the processing surface of the board changes, the hot press element 73 can also slide on the heat-conducting element 72 to flexibly change its working position and achieve full adhesion to the processing surface.

[0051] Existing edge banding machines generally use a single-layer hot press roller, which is a single metal tube that can generate heat and is fixedly installed inside the machine. However, the extrusion pressure generated by repeated processing can cause certain deformation to the metal surface, thereby affecting the pressing effect and causing the edge banding tape to fall off after a period of use. Furthermore, the design of a single-layer hot press roller makes replacement difficult and maintenance costs high. Therefore, the hot press roller 7 designed in this invention can effectively solve the above problems. The hot press element 73 can buffer the pressure on the heat conduction element 72, extending the service life of the heat conduction element 72. Moreover, the hot press element 73 has low cost and is easy to replace, reducing the machine's maintenance costs.

[0052] like Figure 9As shown, the discharge device 8 includes a discharge channel 81, an elastic alloy 82, and a pressure plate 83. The discharge channel 81 is an arc-shaped channel with a length of 70 mm and a width of 20 mm. The arc-shaped channel is made of aluminum alloy. The elastic alloy 82 is fixedly installed on the discharge channel 81 by bolts. The elastic alloy 82 is an arc-shaped alloy plate made of nickel-based alloy material with a thickness of 1 mm, which has good elasticity and corrosion resistance. The pressure plate 83 is rotatably installed on the discharge channel 81. The pressure plate 83 is made of aluminum alloy plate with a size of 45×30 mm and a thickness of 2 mm. The elastic alloy 82 is fixedly installed between the discharge channel 81 and the pressure plate 83.

[0053] When processing irregularly shaped plates, the pressure plate 83 is subjected to pressure from the processing surface. The pressure plate 83 transmits the pressure to the elastic alloy 82, which deforms under the force, causing the pressure plate 83 to change its working angle. At the same time, the elastic alloy 82 gives the pressure plate 83 a reaction force, so that the pressure plate 83 tightly adheres the edge banding to the processing surface of the irregularly shaped plate. When the processing is completed, the elastic alloy 82 restores its shape, causing the pressure plate 83 to return to its initial working position.

[0054] Existing edge banding machines only position the edge banding strip on the processing surface of irregular-shaped boards, and cannot fully adhere to the processing surface of irregular-shaped boards throughout the process. Furthermore, they cannot apply pressure to the edge banding strip to adhere to the processing surface, which can easily cause it to fall off after positioning, resulting in uneven edge banding quality problems. The discharge device 8 designed in this invention applies a certain pressure to the edge banding strip while positioning, so that it adheres to the processing surface, preventing it from falling off after positioning, facilitating subsequent processing, and improving the stability of edge banding quality.

[0055] like Figure 10As shown, the shelf 9 includes a first swing arm 91, a second swing arm 92, a base 93, and a suction cup 94. The first swing arm 91 is rotatably mounted under the base plate 1 via a pin. The first swing arm 91 is 200 mm long and is made of lightweight BMT-SSG-500 aluminum alloy, making it easy to handle and install. It has a diameter of 12 mm. The second swing arm 92 is hinged to the free end of the first swing arm 91. The second swing arm 92 is also made of the aforementioned BMT-SSG-500 aluminum alloy. The device is 300 mm long. The other end of the second swing arm 92 is rotatably mounted with the base 93. The base 93 has a diameter of 160 mm and a thickness of 5 mm. The base 93 is made of 6061-T6 aluminum alloy and is lightweight, high-strength, and easy to process and form. It is suitable for supporting different boards in the edge banding machine. The suction cup 94 is fixedly mounted on the base 93. The suction cup 94 is a neoprene rubber suction cup with a diameter of 80 mm and is suitable for adsorbing smooth wood boards.

[0056] When it is necessary to fix the processing board, the board to be processed is placed on the suction cup 94 and fixed. The first swing rod 91 can rotate freely around the installation position of the base plate 1, and the second swing rod 92 can rotate freely around the installation position of the first swing rod 91. Thus, the support rack 9 can move freely in the horizontal position, and the base plate 93 can rotate freely around the installation position of the second swing rod 92. Therefore, the processing board can rotate freely, which facilitates the edge banding processing of the board.

[0057] The existing edge banding machine has a small worktable, which cannot accommodate large-sized boards. Moreover, after processing one side of a normal-sized board, it is necessary to manually turn it to process other sides, which reduces processing efficiency and increases manual labor. Therefore, the support rack 9 in this invention solves the problem of fixing the boards during processing, making it easier for workers to perform edge banding processing on the boards and improving the processing efficiency of the edge banding machine.

[0058] Example 2: Due to the different edge banding tapes used, for general hot-melt edge banding tapes, setting the hot-pressing temperature in Example 1 can form an integrated edge banding effect with the board surface, making the board surface smoother, more beautiful, and with good durability. For PVC edge banding tapes, the heat resistance temperature is generally around 65℃-70℃, so the heating temperature of the heat-conducting element 72 can be set at around 70℃ to prevent the edge banding tape from being damaged by excessively high temperatures.

[0059] Example 3: Acrylic edge banding performs well at high temperatures and has excellent UV resistance and durability, but it is relatively fragile. Therefore, the hot pressing element 73 can be made of polyurethane material, which has a lower hardness than silicone rubber, and the pressure plate 83 is made of silicone rubber material, which has a lower hardness than aluminum alloy, to prevent the edge banding from breaking due to excessive pressure.

[0060] Normally, after the worker fixes the board to the support rack 9, they push the board against the glue applicator 5 and the hot press roller 7. The glue applicator 5 and the hot press roller 7 transmit the pressure to the flexible element 25. Then, through the cooperation of the support plate 24 and the support element 23, the arc-shaped slider 212 slides on the arc-shaped guide rail 211, changing the working position of the glue applicator 5, the hot press roller 7, and the discharge device 8. This makes the glue applicator plate 54, the pressure plate 83, and the hot press element 73 tightly adhere to the processed surface of the board. At the same time, the glue storage box 55 dispenses glue, and the glue applicator plate 54 evenly applies hot melt glue to the processed surface of the board. As the board rotates, the material cutting device... The edge banding tape is fed into the discharge channel 81 by the 4th unit. Then, the pressure plate 83 attaches the edge banding tape to the processing surface of the board. The board continues to rotate, and the heat-conducting element 72 increases the temperature of the hot-pressing element 73. The hot-pressing element 73 presses the edge banding tape attached to the processing surface of the board tightly. When the sensor 6 detects that the edge banding is completed, it transmits a material cut-off signal to the power supply element 43. The material cut-off device 4 cuts off the edge banding tape with a cutting blade. After processing is completed, the operator can rotate the handle 221 to push the fixing block 223 into the rectangular groove of the sliding device 21, lock the sliding device 21, place new edge banding tape on the material tray 3, and add new hot melt adhesive to the glue storage box 55.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
