[0002] Edge banding machines are commonly used equipment in woodworking, mainly for banding the outer edges of boards. Common edge banding machines on the market include the Yintai F12-3 stacked arm curved surface edge banding machine and the Yintai F10 curved and straight line edge banding machine, both produced by KONAY Yintai Equipment (Shandong) Co., Ltd.

[0003] However, in actual production, the demand for edge banding inside the boards is becoming increasingly prominent, especially for boards with small internal holes, where the existing edge banding machine structure has significant shortcomings. Traditional edge banding machines typically have their guide devices located on the upper table, a layout that makes them unsuitable for the special working conditions of edge banding the inside of boards. When edge banding the inside of a board is required, existing equipment lacks an effective guiding mechanism to ensure the edge banding strip accurately enters the cavity, severely impacting edge banding quality and processing efficiency.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: In existing technologies, edge banding machines generally employ fixed guiding devices, which are typically installed above the machine table and are suitable for edge banding the outer edges of boards. However, with the increasing demand for edge banding inside boards in the furniture manufacturing industry, especially when processing boards with small internal holes, traditional guiding devices have revealed significant shortcomings. Due to the limitations of the equipment structure, operators find it difficult to adjust the conveying path of the edge banding strip within the confined space. This results in the edge banding strip failing to accurately enter the glue pot assembly, frequently causing jamming or misalignment, severely impacting processing quality and production efficiency.

[0024] To address these issues, researchers discovered that the rigid installation method of traditional guide devices limited their spatial adaptability. Analysis of the operational characteristics of sealing the inner cavity revealed the need to construct a three-dimensionally adjustable guide system. First, a vertically adjustable support structure was considered; second, horizontally movable guide components needed to be designed; and finally, the system's operability in confined spaces had to be ensured. After numerous trials and verifications, it was determined that vertical adjustment and horizontal retraction functions would be integrated into a single mechanism, forming a composite motion system.

[0025] like Figure 1 As shown, the inner edge sealing machine includes a base box 200, and a table 300 is provided on the top of the base box. A rectangular through hole 301 is formed in the middle of the table. The edge sealing strip guide mechanism 100 extends from the bottom box through the rectangular through hole to the top of the table and is connected to the glue pot assembly.

[0026] An edge banding guide mechanism includes several optical shafts 201, the top of which is fixedly connected to the bottom of a table. Linear bearings 203 are slidably fitted on the optical shafts. A lifting frame 204 is fixedly connected between the multiple linear bearings. A lower plate 205 is provided at the bottom of the optical shafts. A vertical adjustment component is provided between the lifting frame and the lower plate. A retraction component is provided on the lifting frame. A moving component 2 is connected to the retraction component. An edge banding guide groove 1 is connected to the lifting frame. The retraction component enables the moving component to move closer to or away from the edge banding guide groove.

[0027] Furthermore, a flange 202 is provided at the top of the optical axis, and the flange is fixedly connected to the bottom of the table by bolts.

[0028] The optical axis refers to a vertically mounted cylindrical guide rod, which can be made of surface-hardened alloy steel, serving as the vertical motion reference for the entire mechanism. The linear bearing is a sliding component fitted onto the optical axis, which can be a linear motion bearing with a ball bearing cage, ensuring smooth movement of the lifting frame along the optical axis. The lifting frame is a frame structure connecting multiple linear bearings, which can be formed by welding steel plates and supports the various functional modules of the guiding system. The vertical adjustment component is a mechanical device that controls the height of the lifting frame, which can be implemented using a screw and nut transmission mechanism, allowing for precise height adjustment by rotating a handwheel. The retraction component is the actuator that drives the horizontal movement of the moving component, which can be implemented using a cylinder-driven slider guide system for quickly retracting the guiding component during maintenance. The moving component is the movable platform that supports the edge banding conveyor, which can be implemented using a motor-driven wheel system to ensure stable conveying of the edge banding. The edge banding guide groove is a channel structure that guides the edge banding, which can be formed by bending an arc-shaped plate, with its end extending obliquely upwards to accommodate the angle of the inner cavity entrance.

[0029] Specifically, the optical axis and the platform form a rigid support frame, and the linear bearing slides along the optical axis, driving the entire lifting frame to rise and fall. The vertical adjustment component changes the distance between the lifting frame and the lower plate through screw transmission, achieving vertical position adjustment. When it is necessary to clear blockages, the retraction component pushes the moving component horizontally backward, allowing maintenance personnel to access the internal passage. The inclined end of the edge sealing strip guide groove works in conjunction with the conveyor wheel system of the moving component to form a continuous guide path. All functional modules are rigidly connected to form a whole, achieving multi-dimensional position adjustment while maintaining structural stability.

[0030] Compared to existing technologies, traditional guiding devices use a fixed installation method. This solution, through a height-adjustable guiding mechanism, allows for height adjustment according to actual working conditions and different edge banding strip thickness and curvature requirements, thus avoiding and reducing edge banding strip jamming. It also features a horizontal retraction function, solving the drawback of traditional equipment requiring complete disassembly for maintenance. This composite adjustment mechanism overcomes spatial limitations, enabling the guiding system to flexibly adapt to various internal edge banding operation needs.

[0031] Through the above technical solution, this application achieves precise guidance of the edge banding strip during internal cavity edge banding operations. The lifting mechanism can be used with edge banding strips of different thicknesses and curvatures, and the horizontal retraction function facilitates quick handling of jamming faults. The inclined design of the guide groove effectively guides the edge banding strip into narrow spaces, ensuring the continuity of the conveying path. This mechanism significantly improves the processing accuracy and operational convenience of internal cavity edge banding.

[0032] In at least one embodiment, the vertical adjustment assembly includes a screw 208, a digital display sleeve and a position display are formed on the lower plate, the screw is threaded into the digital display sleeve, a handwheel 207 is installed at the bottom of the screw, an L-shaped plate 206 is formed on the inner wall of the lifting frame, the L-shaped plate has a through hole, a nut is welded to the bottom of the L-shaped plate, the nut is directly below the through hole, and the two are coaxial, the top of the screw is threaded into the nut. The vertical height of the lifting frame can be adjusted by rotating the handwheel, and the specific lifting value can be viewed with the help of the position display.

[0033] The components include: a digital display sleeve (a positioning sleeve with a threaded structure, typically a metal tube with internal threads, used to form a threaded drive pair with the screw); a position indicator (a measuring device integrating a displacement sensor, typically a digital optical or magnetic ruler, used to display the axial displacement of the screw in real time); a handwheel (an operating component with a rotating handle, typically an aluminum alloy cast disc, used to provide a point of force for manually rotating the screw); an L-shaped plate (a support component with a right-angle bend, typically a steel plate bent into shape, used to support the nut and transmit the load of the lifting frame); a through hole (a circular hole penetrating the plate, typically machined using drilling technology, used to provide axial movement space for the screw); and a nut (a fastener with internal threads, typically a hexagonal copper nut, used to form a threaded pair with the screw to drive the lifting frame). Specifically, the screw is axially constrained by a threaded joint and a digital display sleeve. When the handwheel is rotated, the screw undergoes axial displacement within the digital display sleeve. This displacement is converted into a digital signal output in real time via a position display, allowing the operator to visually read the adjustment value. The L-shaped plate is fixed to the inner wall of the lifting frame by welding, and the nut welded to its bottom forms a threaded connection with the top of the screw. The axial displacement of the screw is directly converted into the vertical movement of the lifting frame. A through hole is located at the center of the L-shaped plate, with a diameter larger than the outer diameter of the screw, ensuring the screw's free movement while avoiding structural interference. This adjustment assembly achieves precise control of the lifting frame height through the synergistic effect of mechanical transmission and digital display feedback. In at least one embodiment, the lifting frame includes a central plate 2042 with a rectangular hole 2041 formed in the center. A left plate 2043 and a right plate 2044 are respectively provided on both sides of the central plate. A plurality of linear bearings are fixedly connected to the left plate and / or the right plate by bolts. The L-shaped plate is fixedly connected to the inner wall of the left plate.

[0034] Furthermore, the center plate is provided with a fixing block 11, and the fixing block is equipped with a guide groove for the edge sealing strip.

[0035] The center plate refers to the flat plate component that supports the main structure of the lifting frame. It can be made of steel plate with a thickness of 8-12mm, cut into shape, and rectangular holes provide clearance for the movement trajectory of the moving components. The left and right plates refer to the support plates that are vertically welded to both sides of the center plate. They can be made of L-shaped bent steel plates to form a symmetrical layout on both sides to enhance structural rigidity.

[0036] Specifically, the center plate, as the core load-bearing component of the lifting frame, features a rectangular hole design that allows the slide rails in the moving assembly to pass through, preventing movement interference. The left and right plates are symmetrically distributed on either side of the center plate, forming a stable double-sided support structure. By adjusting the installation position of the bolts on the left or right plate, the distribution spacing of the linear bearings can be changed to accommodate different optical axis layouts. The L-shaped plate is welded to the inside of the left plate, and its vertical bending surface forms a threaded connection with the screw of the vertical adjustment assembly. When the screw rotates, it drives the entire lifting frame to move vertically along the optical axis. This structural layout expands the height adjustment range of the edge banding guide groove while ensuring that all components maintain synchronous movement during lifting. In at least one embodiment, the retraction assembly includes a slide rail 31, a slider 32, a first cylinder 34, and a hinge seat 33. Two slide rails are respectively located on either side of a rectangular hole. Sliders are slidably fitted onto the slide rails. A moving assembly is fixedly connected to a plurality of sliders. A hinge seat is mounted on the center plate, and a first cylinder is rotatably connected to the hinge seat. The extension rod of the first cylinder is rotatably connected to the moving assembly. The extension and retraction of the first cylinder can drive the moving assembly to move along the slide rails.

[0037] The slide rail refers to a metal track with a linear guiding structure, which can be made of high-carbon steel with a chrome-plated surface, providing a low-friction linear motion path for the slider. The slider is the sliding component that matches the slide rail, which can be implemented using a slider structure with built-in ball bearings to ensure smooth displacement of the moving component on the slide rail. The hinge base is a mounting base with a rotating shaft, which can be implemented using a U-shaped bracket structure with a copper sleeve, allowing the first cylinder to adjust its angle around the shaft. The rotatable connection refers to an assembly method where components can rotate relative to each other, which can be implemented using a pin and bushing mating structure to eliminate motion interference during cylinder extension and retraction. Specifically, when the sealing strip becomes blocked in the channel, the first cylinder pulls the moving component outward along the slide rail via a telescopic rod. Because the slide rails are symmetrically distributed on both sides of the rectangular hole, the moving component maintains a horizontal movement trajectory under the constraint of the double slide rails, avoiding jamming caused by offset. The hinged seat allows the cylinder to adaptively adjust the installation angle during extension and retraction, ensuring that the driving force is effectively transmitted to the moving component. The matching accuracy between the slider and the slide rail can be controlled within 0.05mm; for example, using HIWIN brand linear guides allows the moving component's retraction stroke to reach a working range of 50-80mm. After cleaning, the first cylinder reverses its movement to precisely reset the moving component to its initial working position. Through the above technical solution, this application can complete the retraction of the moving component within 30 seconds, allowing operators to directly contact the blocked area for cleaning. The position adjustment accuracy of the moving component can reach ±0.1mm, for example, by adjusting the cylinder stroke to control the movement distance, adapting to the guiding requirements of different edge banding strip specifications. After the cleaning operation is completed, the equipment can return to production status within 10 seconds, improving efficiency by more than 80% compared to traditional maintenance methods.

[0038] In at least one embodiment, the moving assembly includes a moving plate 21, which is fixedly connected to the slider by bolts. A rotating shaft 22 is provided in the middle of the moving plate, and a swing plate 23 is rotatably connected to the rotating shaft. A second cylinder 25 is rotatably connected to the moving plate, and the telescopic rod of the second cylinder is rotatably connected to the swing plate. A first guide wheel 24 is provided at the end of the swing plate. In cooperation with this, a motor 27 is provided at the bottom of the moving plate. The output shaft of the motor passes through the moving plate and is connected to an active drive wheel 26. The first guide wheel cooperates with the active drive wheel. When the edge banding strip is clamped between the two, the second cylinder can drive the first guide wheel to approach the active drive wheel, so that the edge banding strip is clamped between the first guide wheel and the active drive wheel, thereby driving the edge banding strip to move.

[0039] The swing plate is provided with a fixed plate 213, which is bent at 90° to form a fixed guide plate 221. The swing plate is provided with a fixed shaft 217, and a deflection plate 218 is rotatably connected to the fixed shaft. The deflection plate is bent at 90° to form a deflection guide plate 220 that cooperates with the fixed guide plate. The deflection plate is provided with a second guide wheel 215 and a pressing wheel 219. The fixed plate is equipped with an edge sealing strip encoder 222 and a third guide wheel 214. An encoder wheel 223 is connected to the output shaft of the edge sealing strip encoder. The encoder wheel cooperates with the pressing wheel, and the second guide wheel cooperates with the third guide wheel. A flexible spring 216 is provided between the fixed plate and the deflection plate.

[0040] The encoder wheel and extrusion wheel work together to detect the movement of the edge banding strip through mechanical contact. This can be achieved using a combination of a rotary encoder and a rubber wheel. The encoder wheel generates pulse signals as the edge banding strip moves, used for real-time monitoring of the conveying speed. The active drive wheel is a conveying wheel directly driven by a motor, typically a metal wheel with anti-slip texture. It drives the edge banding strip by creating a clamping force with the first guide wheel. The multi-stage guide wheel assembly is a progressive constraint structure consisting of a second guide wheel, a third guide wheel, an encoder wheel, an extrusion wheel, and the first guide wheel. This can be achieved using a combination of nylon wheels of different diameters, used to correct the edge banding strip's trajectory in stages. Specifically, when the edge banding strip enters the guide path from below, it is first clamped by the second and third guide wheels to form an initial position. Then, it enters the monitoring section composed of the encoder wheel and the extrusion wheel. At this time, the moving speed of the edge banding strip is fed back to the control system in real time via the encoder. When an abnormal speed is detected, the motor-driven drive wheel immediately stops to prevent further blockage. Under normal conveying conditions, when the edge banding strip passes through the channel formed by the fixed guide plate and the deflection guide plate, the flexible spring allows the deflection plate to adaptively adjust the guide gap according to the thickness of the edge banding strip, avoiding hard jamming. Finally, the edge banding strip is stably output to the cutter head under the high-precision clamping of the first guide wheel and the drive wheel, completing the staged control of the entire conveying process. Through the above technical solution, this application can sense the conveying status of the edge banding strip in real time and automatically stop abnormal conveying. The progressive constraint of multi-level guide wheels maintains the straightness of the edge banding strip, ensuring that the edge banding strip is always under control during vertical conveying, thus solving the problem of blockage caused by poor path during inner edge banding.

[0041] Furthermore, the movable plate is provided with a positioning plate 31, which has a threaded hole. Correspondingly, the center plate is provided with a positioning handwheel 32. The screw on the positioning handwheel can be threaded into the threaded hole of the positioning plate to lock and fix the lifting frame and the movable component.

[0042] The positioning plate refers to a metal plate structure fixed to the moving plate. It can be made of 5-8mm thick steel plate and secured with bolts. The threaded hole is a through-hole structure penetrating the positioning plate, typically machined with standard M10-M16 threads, used to form a threaded connection with the screw of the positioning handwheel. The positioning handwheel is a screw assembly with a rotating handle, typically made of aluminum alloy and assembled with a stainless steel screw. Axial displacement of the screw is achieved by manual rotation.

[0043] Specifically, during normal operation, the screw of the positioning handwheel is screwed into the threaded hole of the positioning plate to form a rigid constraint, keeping the moving plate and the center plate relatively fixed and ensuring the geometric accuracy of the edge banding strip's transmission path. When jamming of the edge banding strip is detected during vertical conveying, the operator unscrews the positioning handwheel to release the mechanical connection between the moving plate and the center plate. At this time, the piston rod of the first cylinder retracts, causing the moving plate to move backward along the slide rail, widening the gap between the drive wheel and the first guide wheel, creating sufficient operating space for cleaning up any tangled or accumulated edge banding strips. After cleaning, the moving plate is reset and relocked by the positioning handwheel, restoring the equipment to normal operation.

[0044] Furthermore, the flexible spring can drive the compression wheel to move toward the encoder wheel, so that the two come into contact.

[0045] Furthermore, the fixed guide plate has an encoder wheel slot for accommodating the encoder wheel; the deflection guide plate has an extrusion wheel slot for accommodating the extrusion wheel, thus preventing the fixed guide plate and the deflection guide plate from interfering with the extrusion wheel and the encoder wheel.

[0046] Furthermore, the movable plate is provided with a third cylinder 28, the telescopic rod of the third cylinder is connected to a cutting blade 29, the movable plate is provided with a cutting blade seat 224, the cutting blade seat forms a channel for accommodating the edge banding strip to pass through, and the cutting blade can cut the edge banding strip passing through the channel under the action of the third cylinder.

[0047] The third cylinder is an SMC C85 series standard cylinder with a 32mm diameter and 50mm stroke. It can output a cutting force of 480N under a 0.6MPa supply pressure, ensuring reliable cutting of various edge banding strips (including PVC, ABS, wood grain paper, etc.) with a thickness of 0.4-3.0mm. The cutter is made of SKH-9 high-speed steel, which achieves a hardness of HRC60±2 after vacuum quenching. The cutting edge is enhanced with laser cladding for improved wear resistance, and its thickness is designed to be 1.5mm to ensure concentrated cutting force.

[0048] In at least one embodiment, such as Figure 5As shown, the edge banding guide groove includes an arc-shaped base plate 12, on which an outer arc-shaped plate 13 and an inner arc-shaped plate 14 are formed. A channel for accommodating the edge banding strip is formed between the outer arc-shaped plate and the inner arc-shaped plate. Connecting plates 15 are formed on both sides of the arc-shaped base plate. An elongated hole 151 is provided on the connecting plate. The end of the arc-shaped base plate is twisted obliquely upward.

[0049] In a specific embodiment, the arc-shaped bottom plate is twisted diagonally upwards towards the glue pot assembly from the bottom to the top.

[0050] The curved base plate refers to a plate-shaped component with a curved structure. It can be made from stamped or injection-molded metal sheets, or through die casting, casting, welding, or 3D printing. Its radius of curvature can be adjusted according to the dimensions of the edge banding machine and glue pot assembly. It guides the edge banding strip along a predetermined path. The outer and inner curved plates are two parallel curved sidewalls on the curved base plate, which can be fixed by welding or integral molding. The distance between them forms a lateral limiting channel to prevent the edge banding strip from shifting laterally during bending. The connecting plates are mounting components on both sides of the curved base plate, which can be formed by bending steel plates. The elongated holes are used to connect to the main body of the equipment via bolts, allowing adjustment of the horizontal position of the guide groove along the direction of the elongated holes. The upward tilting of the curved base plate ends refers to the upward tilting deformation structure at the outlet end. This can be achieved through hot bending, creating an angle at the edge banding strip outlet that matches the inlet angle of the plate's inner cavity. Specifically, the edge banding strip is bidirectionally constrained by the outer and inner curved plates as it moves within the channel. The upward tilt and twist of the curved bottom plate at the exit end causes the edge banding strip to move upward as it leaves the guide groove, facilitating its entry into the existing glue pot assembly at a specific angle. During implementation, the installation position of the guide groove can be fine-tuned according to the dimensions of the edge banding machine and the glue pot assembly, while the curvature of the curved bottom plate can be customized according to different product requirements.

[0051] Furthermore, an outer guide plate 131 is formed at the end of the outer arc-shaped plate, and an inner guide plate 141 is formed at the end of the inner arc-shaped plate. The outer guide plate and the inner guide plate form a guide opening for the edge sealing strip.

[0052] Furthermore, at least one set of height-limiting guide components 16 are formed on the arc-shaped base plate. The height-limiting guide components include a central screw 161. A positioning hole for the central screw to pass through is formed on the arc-shaped base plate. An eccentric wheel 164 is threadedly connected to the central screw. The bottom of the eccentric wheel abuts against the arc-shaped base plate. An upper fastening nut 165 and a lower fastening nut 167 are threadedly connected to the central screw. The lower fastening nut is located at the bottom of the arc-shaped base plate, and the upper fastening nut is located at the top of the eccentric wheel. Several bearings 166 are rotatably connected to the eccentric wheel. A height-limiting plate 162 is provided at the top of the central screw. A height-limiting guide wheel 163 is rotatably connected to the height-limiting plate.

[0053] The adjustment of the edge banding thickness is related to the curvature of the edge banding. The height-limiting guide assembly refers to the guide structure used to adjust the height and width of the passageway. Specifically, it can use a central screw and an eccentric wheel to achieve passageway width guidance adjustment. The central screw passes through a positioning hole and is fixed in position by upper and lower fastening nuts, thereby controlling the position of the eccentric wheel.

[0054] Due to different board material requirements, when it is necessary to replace the edge banding strip with different thicknesses, the different degrees of curvature may cause the edge of the edge banding strip to touch the outer and inner curved plates, resulting in increased frictional resistance. Therefore, the channel width can be adjusted by using a central screw and an eccentric wheel to accommodate edge banding strips of different thicknesses.

[0055] The eccentric wheel refers to an eccentric structure that adjusts the travel path of the edge banding strip by rotation. Specifically, it can be implemented using a wheel with bearings. The bearings reduce friction when in contact with the edge banding strip. Without bearings, the edge banding strip directly rubs against the outer and inner curved plates, resulting in significant resistance. Adding bearings reduces the resistance during guidance. The channel width cannot be too wide or too narrow. Too wide a channel can lead to excessive movement of the edge banding strip, causing guide deviation; too narrow a channel can cause blockage. The eccentric wheel design allows for adjustment of the channel width to accommodate edge banding strips of different widths. The positioning hole is a hole structure used to fix the position of the central screw. Specifically, it can be implemented using a round hole or a long hole matching the diameter of the central screw. After the central screw passes through the positioning hole, it is clamped and fixed by upper and lower fastening nuts, ensuring the stability of the height-limiting guide assembly.

[0056] Through the above technical solution, this application can correct the height deviation during the edge banding strip conveying process, effectively eliminate jamming, ensure that the guide wheel and the edge banding strip always maintain the best contact pressure, and ensure the smooth conveying of the edge banding strip in the guide channel.

[0057] Furthermore, the eccentric wheel includes a lower column 1642 and an upper hexagonal portion 1641, the lower column and the upper deformable portion are integrally formed, and a through eccentric hole 1643 is formed in the middle of the eccentric wheel.

[0058] The lower column refers to the cylindrical structure at the bottom of the eccentric wheel, which can be machined from metal to provide a contact support surface with the curved base plate. The upper hexagonal part refers to the hexagonal prism structure at the top of the eccentric wheel, which can be achieved using a hexagonal wrench to facilitate adjustment of the eccentric wheel angle via standard tools. One-piece molding means that the lower column and upper hexagonal part are formed as a single structure through casting or machining, which can be completed in one step using a CNC milling machine to ensure structural strength and avoid assembly errors. The through-hole refers to a through hole offset from the geometric center of the eccentric wheel, which can be machined by offsetting the central axis during drilling, used to accommodate the central screw and enable the eccentric wheel position adjustment function. Specifically, the eccentric wheel is fitted onto the central screw through a through-hole. When the upper hexagonal part is rotated, the eccentric wheel undergoes radial displacement around the axis of the central screw. Because the eccentric hole is off-center from the geometric center, the rotation of the eccentric wheel changes the contact position between its bottom and the curved base plate, thereby adjusting the width of the edge banding channel.
