Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically, to an edge banding strip linkage oblique cutting device. Background Technology

[0002] Currently, edge banding machines generally use a straight-line cutting method during processing, cutting the edge banding strip through the cooperation of a fixed blade and a moving blade. This traditional cutting method has obvious drawbacks: First, straight-line cutting easily causes wrinkles and deformation of the edge banding strip, affecting the product's appearance quality; second, the cut edge banding strip has a right-angled end, which easily exposes cutting marks during subsequent installation, affecting the overall aesthetics. Furthermore, the straight-line cutting method requires operators to leave a few millimeters of length for manual trimming after cutting. This not only increases the complexity of the process but also makes it difficult to guarantee the quality of manual trimming, easily resulting in uneven cuts at the joints, severely affecting the overall aesthetics of the finished board.

[0003] To address the aforementioned issues, Chinese patent CN105382872B discloses an edge banding tape cutting device. This device uses a motor-driven circular blade for cutting, achieving a relatively neat cut edge. However, this cutting method still has significant shortcomings: since the edge banding of the board is a continuous process, the edge banding tape needs to be clamped and fixed during cutting, which affects the normal edge banding process of the board, causing tension on the edge banding tape and resulting in localized deformation. Furthermore, regardless of whether straight cutting or saw blade cutting is used, a new zero point needs to be found after the edge banding tape is cut as a reference for subsequent edge banding of the board, which wastes production time and reduces processing efficiency. In addition, the existing technology cannot achieve synchronous compensation movement of the edge banding tape during the cutting process, resulting in unstable cutting quality and difficulty in achieving the process requirement of concealed beveled cut edges. Therefore, the existing technology urgently needs improvement to address these problems. Utility Model Content

[0014] Furthermore, a V-shaped groove is formed on the movable plate, the V-shaped groove is located directly below the limiting plate, and a fan-shaped hole is formed on the platform.

The linear bearing assembly is installed between the moving plate and the table surface, and the linkage cylinder can drive the moving plate to move.

[0016] Furthermore, the length of the rectangular slot is greater than the length of the third hinge seat, so that the third hinge seat can move along the rectangular slot when the linkage cylinder is activated.

[0033] 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:

[0034] In existing technologies, edge banding machines generally use a straight-line cutting method, cutting the edge banding strip through the cooperation of a fixed blade and a moving blade. This traditional method easily leads to wrinkles and deformation of the edge banding strip, and the exposed right-angled cut ends affect the aesthetics. Existing improved solutions use circular saw blades for cutting, such as the cutting device disclosed in patent CN105382872B. Although this can produce neat edges, the edge banding process continues while the board is being clamped and fixed, causing the edge banding strip to be stretched and deformed during the clamping time. Furthermore, the reference point needs to be repositioned after cutting, increasing the processing time.

[0035] To address these issues, it was discovered that traditional cutting processes suffer from a mismatch between the clamping action and the speed of continuous edge-sealing operations. The momentary pause during clamping causes displacement deviation of the edge-sealing tape, resulting in localized deformation. Simultaneously, the vertical stress generated by straight-line cutting easily causes wrinkles in the edge-sealing tape, and right-angle cuts require manual re-trimming. Analysis revealed that synchronizing the clamping action with the edge-sealing tape movement and altering the cutting angle can eliminate displacement deviation and conceal cut marks.

[0036] like Figures 1-6 As shown, a beveling device for edge banding strips is installed on the table 100 of an existing edge banding machine. It includes a movable plate 6, a beveling mechanism 3, a clamping mechanism 4, and a linkage mechanism. The linkage mechanism is located at the bottom of the table, and the movable plate is fixedly connected to the linkage mechanism. The movable plate is equipped with the beveling mechanism and the clamping mechanism, which cooperate with each other. During cutting, while the clamping mechanism holds the edge banding strip, the linkage mechanism drives the movable plate to move at the same speed as the edge banding strip to compensate for displacement. The beveling mechanism performs a beveling cut to form a concealed beveled edge.

[0037] The linkage mechanism refers to the mechanical component that drives the moving plate and the edge banding tape to move synchronously. Specifically, it can employ a combination of cylinders and linear bearings, eliminating displacement differences caused by clamping actions through speed matching. The moving plate is the movable base that supports the cutting components. Specifically, it can be a metal sheet combined with a guide mechanism to achieve precise horizontal displacement. The beveling mechanism is the device that performs beveling cuts. Specifically, it can use a motor-driven cutting wheel combined with an angle adjustment structure. The clamping mechanism is the execution unit that fixes the edge banding tape. Specifically, it can use a double-headed cylinder to drive the clamping block, forming a stable clamping area between the limiting plate and the clamping block.

[0038] Specifically, the linkage mechanism drives the moving plate to move at the same speed as the edge banding tape at the moment of clamping, eliminating displacement deviation caused by clamping pauses. The beveling mechanism cuts by rotating the cutting wheel at a predetermined angle, with the beveled cut covered and hidden by the adjacent board material. The clamping mechanism keeps the edge banding tape in a stable position during clamping, and the cutting wheel completes a wrinkle-free cut along a set trajectory. The moving plate, through dynamic compensation of the linkage mechanism, ensures seamless connection between the cutting action and the continuous feeding of the edge banding tape. After cutting is completed, the linkage mechanism can return to its initial position without the need for secondary zero-point positioning.

[0039] Compared to existing technologies, while the circular saw blade cutting method in patent CN105382872B improves cut quality, it does not solve the problem of displacement deviation caused by clamping pauses. This solution, through a speed compensation mechanism of a linkage mechanism, synchronizes the clamping action with the movement of the edge banding, avoiding tensile deformation. The concealed beveled fracture formed by the bevel cutting mechanism requires no secondary trimming, directly eliminating the defect of exposed right-angle fractures.

[0040] Through the above technical solutions, this application eliminates the displacement deviation of the edge banding tape caused by clamping pauses, and avoids wrinkles and deformations during the cutting process. The beveled cut conceals cutting marks through a hidden structure, reducing manual trimming steps. The synergistic effect of the linkage mechanism and the bevel cutting mechanism achieves continuous and stable cutting, improving the efficiency of edge banding operations and the aesthetics of the finished product.

[0041] Furthermore, the movable plate is located at the top of the table, and the linkage mechanism can drive the movable plate to move horizontally.

[0042] In at least one embodiment, the movable plate is further provided with a sealing strip guide mechanism 1, wherein the guide component includes an encoder for measuring length. The above-mentioned technical features are all prior art and have been applied to the KN series and F series of KONAY and Yintai equipment (Shandong) Co., Ltd.

[0043] In at least one embodiment, the oblique cutting mechanism includes a fixed plate 2, a first hinge seat 31 on the fixed plate, an mounting plate 33 rotatably connected to one side of the fixed plate, a swing plate 34 on the mounting plate, a first cylinder 32 rotatably connected to the first hinge seat, the telescopic rod of the first cylinder rotatably connected to the swing plate 34, a motor 35 on the mounting plate, and a cutting wheel 36 connected to the output shaft of the motor.

[0044] The fixed plate is the basic support structure that bears the components of the oblique cutting mechanism. It can be made of 8-12 mm thick steel plate welded together and fixed to the moving plate with bolts, providing stable support. The first hinge seat is a rotating support component mounted on the fixed plate. It can be a metal seat with through holes that mates with a rotating shaft, providing a fulcrum for the first cylinder to rotate around the axis. The mounting plate is the transition component connecting the fixed plate and the swing plate. The first cylinder is the power element that drives the swing plate. It can be a telescopic cylinder with a stroke of 50-80 mm, converting the linear motion of the telescopic rod into the rotational motion of the swing plate. The cutting wheel is the rotating tool that performs the oblique cutting action. It can be a carbide disc blade with a diameter of 80-150 mm, driven by a motor to achieve high-speed rotary cutting.

[0045] Specifically, the fixed plate is bolted to the movable plate, and the first hinge seat forms a rotating pair with the cylinder end of the first cylinder. When the extension rod of the first cylinder pushes the swing plate, the mounting plate deflects around its hinge point with the fixed plate, causing the cutting wheel to change its tilt angle. The motor drives the cutting wheel to maintain rotation, and under the push of the cylinder, it cuts into the edge banding strip along a preset trajectory. During the synchronous movement of the movable plate driven by the linkage mechanism, the cutting wheel cuts the edge banding strip at an inclined posture, forming a beveled cut that matches the direction of movement of the edge banding strip.

[0046] Through the above technical solution, this application achieves oblique cutting during the continuous conveying of the edge banding tape, eliminating the wrinkles and deformation caused by traditional straight cutting. The resulting oblique cut surface can conceal seam traces without secondary trimming. The combination of the rotating cutting wheel's entry method and the synchronous compensating movement of the moving plate effectively solves the problem of edge banding tape deformation caused by speed mismatch during the clamping stage, ensuring a flat and smooth cut surface.

[0047] Compared to existing technologies, traditional edge banding cutting mechanisms use linear guides or cylinders to directly drive the cutting wheel for linear displacement, requiring the drive components to be arranged along the cutting direction and occupying a large amount of longitudinal space. For example, in Chinese patent CN105382872B, the motor and circular blade are arranged in a linear manner, resulting in an increase in the overall structural length. This solution, however, uses a rotating connection design between the fixed plate and the mounting plate to convert the displacement of the cutting wheel into rotational motion around an axis, reducing the longitudinal space requirement by more than 50%. Simultaneously, the hinged linkage between the first cylinder and the swing plate replaces the sliding structure of the traditional linear guide, further reducing the lateral layout dimensions.

[0048] Furthermore, the fixed plate is provided with an arc-shaped groove 21, and the movable plate is provided with an arc-shaped lower groove 61. The arc-shaped lower groove is provided with a plurality of threaded holes 62. The threaded holes cooperate with the arc-shaped groove, and the bolt can pass through the arc-shaped groove and be threaded into the threaded hole so that the fixed plate and the movable plate are fixedly connected.

[0049] The reason for setting the cutting wheel angle adjustment is that the bevel angles of the outer arc, straight line and inner arc are different when they are joined. The purpose of angle adjustment is to improve the aesthetics of the edge banding. In this case, the angle range of the cutting wheel relative to the edge banding or edge banding strip after adjustment is preferably between -5° and 20°.

[0050] The arc-shaped slot refers to a curved through-hole on the fixed plate, which can be formed by machining an arc-shaped trajectory. Its length can be a size suitable for the adjustment angle range, such as covering the adjustment range of -5 degrees to 20 degrees. The arc-shaped lower slot refers to the recessed track on the surface of the moving plate corresponding to the arc-shaped slot, which can be formed by CNC milling. The threaded holes refer to threaded through holes that are spaced apart along the length of the arc-shaped lower slot, and can be set in an equidistant manner. The hole spacing is set according to the adjustment accuracy requirements. This structure forms multiple fixed nodes to ensure the connection strength at different angles.

[0051] Specifically, when the bevel angle needs to be adjusted, the fixed plate moves to the target position, at which point the arc-shaped groove aligns with the specific threaded hole. By sequentially passing bolts through the arc-shaped groove and screwing them into the corresponding threaded holes, a multi-point rigid connection is formed between the fixed plate and the moving plate. The axial preload generated by the threaded locking can suppress displacement caused by cutting vibration. To prevent bolt loosening, spring washers can be used. The bolt and spring washer work together to achieve an anti-loosening function. The spring washer is a combination structure of a standard flat washer and a spring washer.

[0052] In at least one embodiment, the clamping mechanism includes a double-headed cylinder 41, which is fixedly connected to a movable plate. A clamping block 43 is connected to the telescopic rod of the double-headed cylinder. A connecting plate 42 is provided at the top of the double-headed cylinder, and a limiting plate 44 is provided at the bottom of the connecting plate. Both ends of the limiting plate are fixedly connected to the movable plate by bolts. The clamping block and limiting plate are made of plastic or bakelite. After initial assembly, the clamping block and limiting plate can be cut with a cutting wheel to form cutting grooves, thus facilitating the subsequent oblique cutting of the edge banding strip.

[0053] The dual-head cylinder refers to a linear drive device with bidirectional synchronous output function, which can be implemented using a dual-piston rod cylinder or a parallel dual-cylinder structure. Its function is to achieve balanced clamping through symmetrical force application. The clamping block is the clamping component that directly contacts the edge banding tape, and can be made of plastic or bakelite. Its function is to cooperate with the limiting plate to form a clamping surface. The connecting plate is the transition structure connecting the dual-head cylinder and the limiting plate, and can be implemented by welding steel plates or bolting. The limiting plate is a plastic or bakelite board with a positioning structure, and its two ends are fixedly connected to the moving plate by bolts to constrain the movement trajectory of the clamping block.

[0054] Specifically, the double-headed cylinder is rigidly connected to the moving plate via a fixed end. Its telescopic rods synchronously drive the clamping blocks on both sides to move towards the limiting plate, forming a symmetrical clamping force that presses the edge banding strip between the clamping blocks and the limiting plate. The double-headed cylinder, through its telescopic rods on both sides, synchronously pushes the clamping blocks towards the limiting plate, clamping the edge banding strip between them. Cutting of the edge banding strip is achieved when the cutting wheel cuts obliquely along the groove. The contact surfaces of the clamping blocks and the limiting plate adopt a planar fit, forming surface contact clamping under the pressure of the double-headed cylinder, eliminating deformation of the edge banding strip caused by localized stress concentration. This application achieves bidirectional symmetrical clamping during the oblique cutting of the edge banding strip, eliminating slippage or twisting deformation of the edge banding strip caused by single-point pressure, and ensuring precise alignment of the cut surface with the preset oblique angle.

[0055] Furthermore, when the edge banding strip is clamped between the limiting plate and the clamping block, the cutting wheel can move under the drive of the first cylinder and rotate under the action of the motor to cut the edge banding strip obliquely.

[0056] Furthermore, such as Figure 6As shown, a V-shaped groove 63 is formed on the movable plate to avoid interference with the cutting wheel. The V-shaped groove is located directly below the limiting plate. Correspondingly, a fan-shaped hole 104 is formed on the table surface. When the linkage mechanism drives the movable plate to perform horizontal compensation movement, the V-shaped groove, the fan-shaped hole, and the limiting plate form a spatial fit, preventing mechanical interference from the cutting wheel during the oblique cutting process.

[0057] In at least one embodiment, the linkage mechanism includes a linkage cylinder 75 and two sets of linear bearing assemblies. A rectangular slot 103 is formed on the table surface. One end of the linkage cylinder is rotatably connected to a second hinge seat 74. The telescopic rod of the linkage cylinder is rotatably connected to a third hinge seat 76. The third hinge seat passes through the rectangular slot and is fixedly connected to the bottom of the movable plate. The linear bearing assemblies are installed between the movable plate and the table surface. The linkage cylinder can drive the movable plate to move.

[0058] The linkage cylinder refers to an actuator that generates linear thrust through pneumatic drive. Specifically, it can be implemented using a double-acting cylinder, with its telescopic rod end connected via a hinge to transmit power, avoiding motion interference caused by rigid connections. The linear bearing assembly is a sliding guide mechanism consisting of a fixed base, a moving optical axis, and a box-type slider. Specifically, it can be implemented using linear ball bearings in conjunction with a hardened steel shaft. A stable support structure is formed through a symmetrical double-track layout, eliminating eccentric loading caused by unilateral force. The rectangular slot is a long, through-hole formed on the table surface, which can be milled. Its length direction is consistent with the movement trajectory of the moving plate, providing displacement space for the third hinge seat and restricting the direction of movement. The second and third hinge seats are connecting components with a rotating fulcrum, specifically implemented using a U-shaped bracket with a self-lubricating bearing. The cylinder thrust is converted into horizontal movement driving force through a rotating pair structure.

[0059] Specifically, when the linkage cylinder extends or retracts, its cylinder body rotates around the second hinge seat, and the extension rod drives the third hinge seat to translate along the rectangular slot, pushing the moving plate to produce horizontal displacement. Two sets of linear bearing assemblies are respectively arranged on both sides of the moving plate, and the box-type slider slides along the moving optical axis, forming a double-track guide system that constrains the moving plate to move only in a set direction. When the linkage cylinder outputs thrust, the linear bearing assemblies bear the lateral load and eliminate mechanical backlash, ensuring that the moving plate does not skew during the displacement compensation process.

[0060] Through the above technical solution, this application achieves stable linear motion of the moving plate during the compensation clamping time displacement process, prevents positioning deviation caused by mechanical structure gaps or off-center load, ensures the synchronization of the actions of the oblique cutting mechanism and the clamping mechanism, and avoids the edge banding tape from shifting position during the cutting process.

[0061] In some embodiments, the linkage cylinder can be equivalently replaced by other linear motion modules, such as... Figure 7 As shown, the linear motion module includes a first lead screw support 771, a second lead screw support 775, a lead screw 774, a rotary motor 776, and a slide rail 772. A slide rail is provided on each side of the rectangular slot, and a slider is slidably fitted onto the slide rail. The first lead screw support and the second lead screw support are respectively provided on the front and rear sides of the rectangular slot. A lead screw is rotatably connected between the first and second lead screw supports. A rotary motor is connected to the end of the lead screw, and the rotary motor is fixedly connected to the bottom of the platform. A ball screw nut is threaded onto the lead screw, and a connecting plate 773 is mounted on the ball screw nut. The connecting plate is connected to the slider on both sides and is fixedly connected to the bottom of the moving plate by bolts. The rotation of the rotary motor drives the moving plate to move along the slide rail.

[0062] In some embodiments, the linear motion module includes, but is not limited to, the two types mentioned above, and may also be a synchronous belt assembly, gear drive, or gear and rack combination, etc.

[0063] Furthermore, the length of the rectangular slot is greater than the length of the third hinge seat, allowing the third hinge seat to move along the rectangular slot when the linkage cylinder is activated. By limiting their length dimensions, sufficient travel space is ensured for the third hinge seat under the drive of the linkage cylinder.

[0064] Furthermore, the linear bearing assembly includes two linear bearing mounting seats 71, a linear bearing movable optical axis 72, and a linear bearing seat box-type slider 73. The platform is provided with two movable slide grooves 102, which are respectively located on both sides of the linkage cylinder. Each end of the movable slide groove is provided with a linear bearing mounting seat. A linear bearing movable optical axis is installed between the two linear bearing mounting seats. A linear bearing seat box-type slider is installed on the linear bearing movable optical axis. The linear bearing seat box-type slider is fixedly connected to the movable plate by bolts.

[0065] Furthermore, the movable plate has positioning holes 64 for convenient installation of linear bearing housing-type sliders.

[0066] The linear bearing mounting base refers to the mounting base used to support and fix the linear bearing's moving optical axis. Specifically, it can be implemented using a metal base with positioning steps, fixed to both ends of the moving slide groove with bolts. Its function is to provide a stable mounting reference for the moving optical axis, ensuring its straightness. The linear bearing moving optical axis refers to a precision shaft serving as a guiding element. Specifically, it can be implemented using a surface-hardened alloy steel optical axis. Its function is to form a high-precision sliding pair with the box-type slider, providing linear motion guidance for the moving plate. The linear bearing box-type slider refers to a sliding component with linear bearings. Specifically, it can be implemented using an aluminum alloy box structure with internally integrated ball bearings. Its function is to achieve low-friction movement through cooperation with the moving optical axis, while being rigidly connected to the moving plate with bolts to ensure synchronous power transmission.

[0067] Specifically, two movable slides are symmetrically arranged on both sides of the linkage cylinder, forming a double-sided guide structure, thereby eliminating the risk of eccentric loading caused by unilateral force. The linear bearing mounting seats at both ends of the movable slides constrain the axial degree of freedom of the movable optical axis through a two-point positioning method, thereby ensuring the linear accuracy of the optical axis after installation. The box-type slider of the linear bearing seat is rigidly connected to the movable plate with bolts, so that the driving force of the linkage cylinder can be evenly transmitted to the movable plate. When the linkage cylinder drives the movable plate, the box-type slider moves linearly along the movable optical axis. The symmetrical double-sided guide structure counteracts the lateral load, thereby achieving smooth, backlash-free movement of the movable plate.

[0068] Through the above technical solution, this application solves the problem of motion jamming and offset caused by off-center load or guide clearance when the linkage mechanism drives the moving plate, ensuring that the moving plate always maintains a straight motion trajectory under the drive of the linkage cylinder. This enables the beveling mechanism and the clamping mechanism to work precisely together, avoiding the cutting position deviation caused by the inaccuracy of the moving plate's movement, and ultimately ensuring the concealment of the beveling cut of the edge banding and the wrinkle-free cutting effect.
