Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically, to an edge banding tape synchronous cutting mechanism. Background Technology

[0002] In the current laser edge banding process, due to its unique process characteristics and quality control requirements, it is impossible to reduce the feeding speed of the edge banding tape and the board when the laser edge banding machine is cutting the edge banding strip. If the bonding speed is reduced during the cutting process, the laser energy will continue to act on a local area of ​​the edge banding tape for too long due to the response delay characteristic of the laser power adjustment system. This phenomenon will cause the heat input of the edge banding tape to exceed the material's tolerance threshold, resulting in quality defects such as thermal damage to the edge banding tape and excessive carbonization of the adhesive layer.

[0003] Existing laser edge banding machines use a fixed cutting mechanism. When cutting at a constant speed, the interaction time between the blade and the edge banding tape is extremely short, generating a strong transient impact force. This impact force is transmitted through the edge banding tape to the entire feeding system. This impact force not only disrupts the continuous and stable conveying of the edge banding tape but also causes instantaneous relative slippage between the feed roller and the edge banding tape. Furthermore, this mechanical impact can lead to quality problems such as scratches on the surface of the edge banding tape. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a synchronous cutting mechanism for edge banding tape.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A synchronous cutting mechanism for edge banding tape is installed on the table of an edge banding machine. A rectangular groove is formed on the table, and a synchronous feeding component is installed at the rectangular groove. A cutting component is fixedly connected to the synchronous feeding component, and the synchronous feeding component can drive the cutting component to move forward synchronously with the edge banding tape.

[0006] Furthermore, the synchronous feed assembly includes a slide rod disposed at the bottom or top of the table, a slider slidably fitted on the slide rod, a translation plate fixedly connected to a plurality of sliders, a threaded sleeve installed at the bottom of the translation plate, a ball screw threadedly connected to the threaded sleeve, the end of the ball screw being connected to a drive motor, and the drive motor being fixedly connected to the bottom of the table.

[0007] Furthermore, the translation plate is capable of moving within a rectangular groove.

[0008] Furthermore, the slide bar is located at the bottom of the table, and a fixed seat is provided on each side of the rectangular slide groove along the feeding direction of the sealing strip, with the slide bar installed between the two fixed seats.

[0009] Furthermore, a support base is provided at the bottom of the tabletop, and a threaded sleeve is fixedly connected to the support base by bolts.

[0010] Furthermore, the translation plate is provided with a fixed shaft, and a guide plate is rotatably connected to the fixed shaft. A lower motor is provided at the bottom of the guide plate. The output shaft of the lower motor passes through the translation plate and is connected to a long shaft bonding wheel. A linear drive assembly is rotatably connected between the translation plate and the guide plate. The linear drive assembly can drive the translation plate to rotate around the fixed shaft so that the edge sealing tape abuts against the surface of the long shaft bonding wheel.

[0011] Furthermore, the fixed shaft is provided with several guide wheels.

[0012] Furthermore, the linear drive assembly is a pneumatic cylinder or an electric cylinder.

[0013] Furthermore, the edge banding machine is a laser edge banding machine.

[0014] Furthermore, the cutting assembly includes a left plate and a right plate arranged in parallel. A fixed cutter head is mounted on the left plate, and a cylinder is mounted on the right plate. A guide rod is provided between the fixed cutter head and the cylinder. A guide block is slidably fitted on the guide rod. A movable cutter head is mounted on the guide block. The telescopic rod of the cylinder is connected to the guide block and can drive the movable cutter head to reciprocate. A retaining spring groove is provided on the guide rod. A limiting plate is provided in the retaining spring groove. The limiting plate is located between the fixed cutter head and the guide block, and a gap is formed between the limiting plate and the fixed cutter head to accommodate the edge banding tape.

[0015] Compared to existing technologies, traditional laser cutting equipment, operating at a constant speed, suffers from insufficient contact time between the blade and the material, leading to impact force being transmitted to the feeding system. This solution eliminates speed differences through synchronous movement, enabling the cutting process to be completed at zero relative velocity. Furthermore, existing technologies often result in material displacement due to inertia after cutting, while this solution ensures precise material entry into subsequent workstations through baffle guidance and synchronous reset actions. Through the above technical solution, this application effectively eliminates the transient impact force at the moment of cutting, avoids slippage damage to the sealing strip caused by displacement fluctuations in the feed system, and ensures the integrity of the material surface. The synchronous reset mechanism, in cooperation with the baffle, ensures the stability of the material conveying path during continuous operation, and the speed tracking control strategy significantly reduces the intensity of dynamic interaction between the tool and the material.

[0017] 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, the instantaneous contact between the blade and the edge banding tape during laser edge banding cutting generates a pulsed mechanical impact, causing relative slippage between the conveyor roller and the edge banding tape, resulting in surface damage to the edge banding tape. Conventional solutions employ a rigid cutting structure, which cannot eliminate the speed difference between moving parts, especially noticeable during high-speed operations. To address the aforementioned issues, researchers observed a close correlation between the generation of transient impact force and the motion state of the cutting device. Analysis revealed that maintaining synchronous motion between the cutting device and the sealing tape effectively extends the blade's action time. Based on the law of conservation of momentum, extending the action time reduces the peak value of the transient impact force. Therefore, a synchronous motion system was proposed to ensure that the cutting device maintains a constant speed with the sealing tape during operation.

[0018] like Figures 1-3 As shown, a synchronous cutting mechanism for edge banding tape is installed on the table 100 of an edge banding machine. A rectangular slide groove 101 parallel to the feeding direction of the edge banding tape 200 is formed on the table. A synchronous feeding component 1 is installed at the rectangular slide groove. A cutting component 2 is fixedly connected to the synchronous feeding component. The synchronous feeding component can drive the cutting component to move forward synchronously with the edge banding tape.

[0019] The rectangular groove refers to the guide groove extending along the direction of the sealing tape's movement. The synchronous feed assembly refers to the transmission mechanism that drives the cutting device to achieve reciprocating motion. Specifically, it can be a combination of a ball screw and a servo motor to ensure that the cutting assembly and the sealing tape maintain speed synchronization. The cutting assembly refers to the functional module that performs the shearing action, including a fixed blade and a moving blade working together. The moving blade is driven by a cylinder to complete the shearing operation. Specifically, when the edge banding tape is conveyed along the set direction, the synchronous feed assembly drives the ball screw to rotate via a servo motor, causing the translation plate to move along the rectangular slide. The translation plate and the edge banding tape maintain the same direction and speed, while the moving blade in the cutting assembly completes the shearing action under the push of the cylinder. Since there is no relative movement between the cutting assembly and the edge banding tape, the blade's action time is extended to the entire synchronous movement process, effectively dispersing the impact energy. After the cutting is completed, the synchronous feed assembly drives the cutting assembly back to the initial position, preparing for the next work cycle. Compared to existing technologies, the fixed installation of current cutting devices results in a speed difference between the cutter and the edge banding tape. This solution addresses this by constructing a synchronous motion system to align their speed vectors. The high-frequency impact generated by traditional rigid cutting is converted into a continuous low-amplitude force, eliminating the pulse load on the feeding system. Effective attenuation of the mechanical impact force prevents relative slippage between the edge banding tape and the conveyor rollers, ensuring surface treatment quality. Through the above technical solution, this application achieves dynamic speed matching between the cutting tool and the material during the edge banding tape cutting process, eliminating system vibration caused by transient impacts. The stability of the feeding system is improved, and the surface scratch rate of the edge banding tape is reduced. This mechanism is particularly suitable for high-speed continuous operation conditions, extending the equipment maintenance cycle while maintaining cutting accuracy.

[0020] In at least one embodiment, the synchronous feed assembly includes a slide bar 11 disposed at the bottom or top of the table, a slider 12 slidably fitted on the slide bar, a translation plate 13 fixedly connected to a plurality of sliders, a threaded sleeve 16 installed at the bottom of the translation plate, a ball screw 15 threadedly connected to the threaded sleeve, the end of the ball screw being connected to a drive motor 14, and the drive motor being fixedly connected to the bottom of the table.

[0021] The components are as follows: A slide bar is a linear guide component that supports the movement trajectory of the translation plate. It can be implemented using a stainless steel rod with a hard chrome-plated surface. Its function is to provide rigid support for the translation plate and constrain its movement direction. A slider is a load-bearing component that forms a sliding pair with the slide bar. It can be implemented using linear bearings or polymer bushings. Its function is to convert the reciprocating motion of the translation plate into low-friction linear displacement. A ball screw is a transmission component that converts rotary motion into linear motion. It can be implemented using ground precision ball screw pairs. Its function is to transmit power through the threaded engagement of the sleeve and the screw. A drive motor is a power output device. It can be implemented using a servo motor or a stepper motor. Its function is to provide controllable rotational power to the ball screw.

[0022] Specifically, the drive motor drives the ball screw to rotate via a coupling, causing the ball sleeve to move axially, which in turn pushes the translation plate to move linearly under the constraint of the slide rod. Multiple sliders are distributed along the axis of the slide rod and rigidly connected to the translation plate, forming a multi-point support structure to enhance the bending stiffness of the translation plate. When the drive motor runs at a preset speed, the translation plate can drive the cutting component to move synchronously with the sealing tape, and automatically reset after completing the cutting action during the movement.

[0023] Furthermore, the translation plate is capable of moving within a rectangular groove.

[0024] Specifically in this embodiment, such as Figure 2 As shown, the slide rod is located at the bottom of the table. A fixed seat 111 is provided on each side of the rectangular slide groove along the feeding direction of the sealing strip, and the slide rod is installed between the two fixed seats. The fixed seat refers to the mounting base used to constrain the axial position of the slide rod. Specifically, it can be a cast iron component with locating pin holes, which is rigidly connected to the table by bolts to ensure that the axis of the slide rod remains parallel to the feeding direction of the sealing strip.

[0025] Furthermore, a support base 161 is provided at the bottom of the tabletop, and a threaded sleeve is fixedly connected to the support base by bolts. The support base refers to the mounting base that supports the threaded sleeve, and can be made of cast iron or welded steel structural components. Its bottom surface can be connected to the bottom of the tabletop by welding or bolts to form a rigid support structure.

[0026] In at least one embodiment, the translation plate is provided with a fixed shaft 32, and a guide plate 34 is rotatably connected to the fixed shaft. A lower motor 31 is provided at the bottom of the guide plate. The output shaft of the lower motor passes through the translation plate and is connected to a long shaft bonding wheel 35. A linear drive assembly is rotatably connected between the translation plate and the guide plate. The linear drive assembly can drive the translation plate to rotate around the fixed shaft so that the edge sealing tape abuts against the surface of the long shaft bonding wheel.

[0027] The fixed shaft refers to a rotating support shaft perpendicular to the plane of the translation plate. It can be implemented using a cylindrical metal shaft with a flange, which is bolted to the surface of the translation plate. A radial through hole at the end of the shaft allows for the installation of a cotter pin for axial positioning. The guide plate is a metal plate with a rectangular cross-section, typically made of aluminum alloy profiles. Its end has a bushing structure with a needle roller bearing for rotatable connection to the fixed shaft. The linear drive assembly is the power device that generates linear thrust. It can be implemented using a double-acting cylinder in conjunction with a displacement sensor. The cylinder body is mounted on the side of the translation plate via a hinge seat, and the piston rod end is connected to the guide plate via a ball joint.

[0028] Furthermore, the fixed shaft is provided with a plurality of guide wheels 33.

[0029] The guide wheel is a cylindrical rolling component mounted on a fixed shaft. It can be made of polyurethane and connected to the fixed shaft via bearings. Its outer circumferential surface contacts the edge banding to provide guidance. The axial spacing of the guide wheels can be adjusted according to the width of the edge banding, for example, using a layout with intervals of 10 mm to 30 mm to ensure the edge banding maintains a stable posture during movement.

[0030] Furthermore, the linear drive assembly is a pneumatic cylinder or an electric cylinder.

[0031] A cylinder is an actuator that uses compressed air to push a piston to produce linear motion. It can be implemented using a double-acting or single-acting cylinder, with its piston rod hinged to the translation plate and guide rail. An electric cylinder is an electromechanical device that converts the rotary motion of a motor into linear motion. It can be implemented using a servo motor in conjunction with a ball screw structure.

[0032] In at least one embodiment, such as Figure 3 and Figure 4 As shown, the cutting assembly includes a left plate 21 and a right plate 22 arranged in parallel. A fixed cutter head 25 is mounted on the left plate, and a cylinder 24 is mounted on the right plate. A guide rod 23 is provided between the fixed cutter head and the cylinder. A guide block 27 is slidably fitted on the guide rod, and a movable cutter head is mounted on the guide block. The telescopic rod of the cylinder is connected to the guide block, which drives the movable cutter head to reciprocate to cooperate with the fixed cutter head to cut the edge banding tape. A retaining spring groove is provided on the guide rod, and a limiting plate 26 is provided in the retaining spring groove. The limiting plate is located between the fixed cutter head and the guide block, and a gap is formed between the limiting plate and the fixed cutter head to accommodate the edge banding tape. Further detailed explanation has been disclosed in Chinese Patent CN212795317U, and will not be explained in detail here.

[0033] Among them, the guide rod refers to a metal rod with axial sliding constraint function, which can be made of surface-hardened alloy steel rod. Its function is to provide a linear motion trajectory for the moving cutter head; the snap ring groove refers to the annular groove structure opened on the surface of the guide rod, which can be formed by CNC machine tool, and is used to fix the position of the limiting plate; the limiting plate refers to a metal plate with thickness constraint function, which can be made of stainless steel plate by stamping.
