Description

Technical Field

[0001] This utility model relates to the field of decorative panel processing technology, specifically to an automatic cutting device for multi-angle decorative panels. Background Technology

[0002] Decorative panels, as a core material for high-end home furnishings and architectural decoration, are made of 0.2mm thin wood veneer precisely bonded to a plywood substrate, combining natural texture with structural stability. Their multi-angle cutting requirements are widespread in custom furniture, irregularly shaped decorations, and other scenarios, including 45° beveling for seamless corner splicing, V-groove processing for artistic bending, and composite angle cutting to meet curved surface shapes.

[0003] The current mainstream cutting equipment mainly adopts a single-arm rotary device. Through the 360° full-angle adjustment mechanism, large angle switching is required during cutting, such as 90°→135°, which results in a time consumption of 3-5 seconds. Moreover, the single-arm rotary design cannot complete the rapid corner cutting of decorative panels.

[0004] Therefore, we propose an automatic cutting device for multi-angle decorative panels to solve the problems mentioned above. Utility Model Content

[0005] This utility model provides an automatic cutting device for multi-angle decorative panels, which can solve the problem that the existing decorative panel cutting device adopts a single-arm rotating design, which requires large-angle switching when cutting at different angles, is time-consuming, and cannot perform corner cutting.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An automatic cutting device for multi-angle decorative panels includes a conveyor table and a multi-angle cutting mechanism. The multi-angle cutting mechanism is disposed on the side of the conveyor table. The conveyor table is provided with an adjustable roller assembly for stabilizing the decorative panels. The multi-angle cutting mechanism includes a cutting table with two sets of stabilizing frames installed on it. A guide seat is installed between the two sets of stabilizing frames, and two sets of angle-adjustable cutting components are installed on the guide seat. A base plate is fixedly connected to the upper end of the conveyor table. Multiple sets of laser displacement sensors are installed on the side of the base plate near the surface of the conveyor table. The laser displacement sensors are used for monitoring the position of the decorative panels. An adjustment component for adjusting the cutting position of the decorative panels is installed on the side of the base plate near the cutting table.

[0008] Preferably, the adjustable roller assembly includes a lifting plate and several strip rollers. One end of each strip roller is rotatably connected to the lifting plate. The strip rollers are arranged in a linear array on one side of the lifting plate. A first electric telescopic rod is fixedly installed on the side wall of the conveyor table. The first electric telescopic rod drives the lifting plate to adjust its height.

[0009] Preferably, the surface of the strip roller is made of rubber, and a pressure sensor is installed between the telescopic end of the first electric telescopic rod and the lifting plate.

[0010] Preferably, the cutting assembly includes a first adjusting seat and a second adjusting seat. A first cutting blade is mounted on the first adjusting seat, and a second cutting blade is mounted on the second adjusting seat. A telescopic cylinder is rotatably connected to the first adjusting seat, and a gear ring is fixedly connected to the outside of the telescopic cylinder. A first high-precision motor is mounted on the first adjusting seat, and a drive tooth is mounted on the first high-precision motor. The drive tooth meshes with the gear ring. An angle encoder is mounted on the drive shaft of the first high-precision motor. The second adjusting seat has the same structure as the first adjusting seat.

[0011] Preferably, the adjustment angle of the first cutting blade is 0-90 degrees, and the adjustment angle of the second cutting blade is 91-180 degrees; in the initial state, the first cutting blade is at 45 degrees and the second cutting blade is at 145 degrees.

[0012] Preferably, the adjustment assembly includes a second electric telescopic rod, which is fixedly installed on the side of the base plate near the cutting table. The telescopic end of the second electric telescopic rod is fixedly connected to the mounting base, and an electric push rod is fixedly connected inside the mounting base.

[0013] Preferably, a second high-precision motor is installed at the telescopic end of the electric push rod, an electrically controlled suction cup is installed on the shaft of the second high-precision motor, and an angle encoder is installed on the shaft of the second high-precision motor.

[0014] Preferably, guide grooves are provided on the inner sides of both stabilizers, and a linear drive rail is installed inside the guide groove on at least one side. The end of the guide seat is slidably connected inside the guide groove, and the linear drive rail drives the guide seat to move horizontally for adjustment.

[0015] Preferably, the guide seat has a groove inside, and the first adjusting seat and the second adjusting seat are both installed inside the groove.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] This utility model adopts a dual-cutting component design, dividing the cutting angle into two working ranges: 0-90° and 91-180°. The first and second cutting blades are controlled by the first and second adjusting seats respectively, which effectively avoids the problem of excessive time consumption when switching large angles in single-arm rotary equipment and significantly improves cutting efficiency.

[0019] By setting the initial angle, the first cutting blade is preset to 45° and the second cutting blade is preset to 145°, which can directly meet the most common 45° corner splicing and 135° beveling requirements, reducing the angle adjustment time and shortening the processing time of standard boards by half.

[0020] Furthermore, by adopting a gear ring transmission mechanism in conjunction with an angle encoder, the cutting angle accuracy is ensured to be controlled within ±0.03°, which solves the backlash problem of traditional worm gear transmission and achieves high-precision cutting, making it particularly suitable for precision corner splicing of decorative panels.

[0021] By adjusting the distance between the two cutting blades using a bidirectional threaded rod, it can operate independently to improve efficiency, or be combined to achieve V-shaped splicing cutting, solving the problem that traditional equipment cannot perform corner cutting.

[0022] The entire device achieves automated positioning and angle adjustment through laser displacement sensors, electrically controlled suction cups, and adjustment components. Combined with an image recognition camera, it enables fully automated operation, greatly improving production efficiency and processing accuracy. Attached Figure Description

[0030] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0031] Example 1:

[0032] Please see Figure 1-6 This utility model provides a technical solution:

[0033] An automatic cutting device for multi-angle decorative panels includes a conveyor table 1 and a multi-angle cutting mechanism, which is used to cut the decorative panels at multiple angles.

[0034] The multi-angle cutting mechanism is located on the side of the conveyor table 1. The conveyor table 1 is equipped with an adjustable roller assembly for stabilizing the decorative panel. The adjustable roller assembly cooperates with the conveyor table 1 to slide and hold the conveyed decorative panel, preventing the decorative panel from moving or shifting.

[0035] The multi-angle cutting mechanism includes a cutting table 4, on which two sets of stabilizing frames 5 are mounted, and a guide seat 6 is installed between the two sets of stabilizing frames 5. The two sets of stabilizing frames 5 support both ends of the guide seat 6.

[0036] Two sets of angle-adjustable cutting components are installed on the guide seat 6, which can cut the decorative panel at multiple angles.

[0037] A base plate 8 is fixedly connected to the upper end of the conveyor table 1. Multiple sets of laser displacement sensors 9 are installed on the side of the base plate 8 near the surface of the conveyor table 1. The laser displacement sensors 9 are used to monitor the position of the decorative panel. When the decorative panel reaches the bottom of the corresponding cutting component, the cutting component is started to cut.

[0038] An adjustment component for adjusting the cutting position of the decorative panel is installed on the side of the base plate 8 near the cutting table 4. The adjustment component moves the decorative panel to adjust the cutting position and angle.

[0039] Furthermore, the adjustable roller assembly includes a lifting plate 11 and several strip rollers 12. One end of the strip rollers 12 is rotatably connected to the lifting plate 11. The strip rollers 12 are linearly arrayed on one side of the lifting plate 11. A first electric telescopic rod 13 is fixedly installed on the side wall of the conveyor table 1. The first electric telescopic rod 13 drives the lifting plate 11 to adjust its height.

[0040] The first electric telescopic rod 13 drives the lifting plate 11 and its connected strip roller 12 to rise and fall, which can adapt to decorative panels of different thicknesses. The surface of the strip roller 12 is made of rubber. A pressure sensor is installed between the telescopic end of the first electric telescopic rod 13 and the lifting plate 11. The rubber material on the surface of the strip roller 12 prevents scratches and wear on the decorative panel. The pressure sensor monitors the pressure between the strip roller 12 and the decorative panel to ensure the stability of the decorative panel and prevent excessive pressure from affecting the conveying.

[0041] Furthermore, the cutting assembly includes a first adjusting seat 15 and a second adjusting seat 16. A first cutting blade 17 is mounted on the first adjusting seat 15, and a second cutting blade 18 is mounted on the second adjusting seat 16. A telescopic cylinder 19 is rotatably connected to the first adjusting seat 15, and a gear ring 20 is fixedly connected to the outside of the telescopic cylinder 19. A first high-precision motor 21 is mounted on the first adjusting seat 15, and a drive gear 22 is mounted on the first high-precision motor 21. The drive gear 22 meshes with the gear ring 20. An angle encoder is mounted on the drive shaft of the first high-precision motor 21. The second adjusting seat 16 has the same structure as the first adjusting seat 15.

[0042] The first cutting blade 17 is pushed down by the telescopic cylinder 19 of the first adjusting seat 15 to cut the decorative panel. The first high-precision motor 21 causes the drive gear 22 to rotate, which drives the gear ring 20 and its connected telescopic cylinder 19 to rotate. The first cutting blade 17 rotates with the telescopic cylinder 19 to adjust the cutting angle. The angle encoder monitors the angle of the first high-precision motor 21 with high precision, which is beneficial to the precise control of the cutting angle.

[0043] The adjustment angle of the first cutting blade 17 is 0-90 degrees, and the adjustment angle of the second cutting blade 18 is 91-180 degrees; in the initial state, the first cutting blade 17 is at 45 degrees, and the second cutting blade 18 is at 145 degrees.

[0044] In the above scheme, the dual-arm cutting system adopts a zoned collaborative design, which realizes efficient multi-angle processing through two independent adjustment seats; the first adjustment seat 15 is responsible for 0-90° cutting, and the second adjustment seat 16 handles 91-180° tasks, reducing the rotation range of a single arm by 50% and significantly improving efficiency.

[0045] When the system is working, the telescopic cylinder 19 of the first adjusting seat 15 drives the cutting blade to press down, and the high-precision motor adjusts the angle through the gear ring 20 mechanism. The encoder monitors in real time to ensure a positioning accuracy of ±0.03°. The initial state is preset to the most commonly used angle, where the first cutting blade 17 is 45° and the second cutting blade 18 is 145°, which can reduce the angle switching time by 65%.

[0046] In actual processing, the intelligent algorithm of the host computer automatically allocates cutting tasks. When the first cutting blade 17 performs acute-angle cutting, it can simultaneously perform obtuse-angle cutting. This parallel operation reduces the processing time of the standard plate by half.

[0047] This design not only improves efficiency but also facilitates maintenance. Replacing a single adjustment seat takes only 15 minutes, and the alternating operation of the dual blades extends the tool life. At the same time, the two first cutting blades 17 and the second cutting blades 18 can be spliced ​​together to cut the decorative panel at the splicing angle, such as a V-shaped cut.

[0048] Example 2:

[0049] Please see Figure 3-4 Furthermore, in conjunction with Embodiment 1, it is further found that the adjustment component includes a second electric telescopic rod 24, which is fixedly installed on the side of the base plate 8 near the cutting table 4, and the base plate 8 provides stable support for the second electric telescopic rod 24.

[0050] The telescopic end of the second electric telescopic rod 24 is fixedly connected to the mounting base 25. An electric push rod 26 is fixedly connected inside the mounting base 25. The second electric telescopic rod 24 pushes the mounting base 25 and the connected electric push rod 26 to slide horizontally linearly.

[0051] The telescopic end of the electric push rod 26 is equipped with a second high-precision motor 27, and an electrically controlled suction cup 28 is installed on the shaft of the second high-precision motor 27. At the same time, an angle encoder is installed on the shaft of the second high-precision motor 27.

[0052] The electric push rod 26 lowers the first high-precision motor 21 and the electrically controlled suction cup 28, which then adheres to and fixes itself to the surface of the decorative panel. The second electric telescopic rod 24 extends and retracts, pushing the first high-precision motor 21 and the electrically controlled suction cup 28 laterally. The electrically controlled suction cup 28 moves the decorative panel closer to or further away from the first cutting blade 17 and the second cutting blade 18, adjusting the cutting position of the decorative panel. Furthermore, the second high-precision motor 27 rotates the electrically controlled suction cup 28 and the decorative panel, adjusting their angle to ensure proper alignment or allow for cutting adjustments over a wider angle range. An image recognition camera is installed on the cutting table 4, and the position and angle of the decorative panel are monitored by the control host, enabling automated cutting.

[0053] Example 3:

[0054] Please see Figure 2 , Figure 5 , Figure 6 Furthermore, in conjunction with Embodiment 1 and Embodiment 2, it is further found that guide grooves 29 are provided on the inner sides of both stabilizers 5, and a linear drive rail is installed inside the guide groove 29 on at least one side. The end of the guide seat 6 is slidably connected to the inside of the guide groove 29, and the linear drive rail drives the guide seat 6 to move horizontally for adjustment.

[0055] The guide seat 6 has a slide groove 31 inside. The first adjusting seat 15 and the second adjusting seat 16 are both installed inside the slide groove 31. A bidirectional threaded rod 32 is installed inside the slide groove 31. A stepper motor that drives the bidirectional threaded rod 32 to rotate is installed on the guide seat 6. The bidirectional threaded rod 32 is composed of two symmetrical threaded rods fixedly connected together.

[0056] The bidirectional threaded rod 32 is driven by a stepper motor. The bidirectional threaded rod 32 is threadedly engaged with the first adjusting seat 15 and the second adjusting seat 16 respectively, so that they move closer or further apart. When the first adjusting seat 15 and the second adjusting seat 16 are close together, the splicing angle can be cut, and the acute angle and obtuse angle can be combined to form a V-shaped corner cut.

[0057] When the first adjusting seat 15 and the second adjusting seat 16 are far apart, the first cutting blade 17 and the second cutting blade 18 can be flexibly adjusted, allowing for independent cutting operations and parallel work, thereby improving production and processing efficiency.

[0058] The stabilizer 5 is U-shaped, with its two ends fixedly connected to the outer sides of the corresponding conveyor table 1 and cutting table 4. The upper surfaces of the conveyor table 1 and cutting table 4 are flush.

[0059] The U-shaped stabilizer 5 spans the conveyor table 1 and the cutting table 4, ensuring sufficient space for movement on the upper parts of the conveyor table 1 and the cutting table 4, which is beneficial for the conveying of decorative panels. The linear drive rail inside the guide groove 29 drives the guide seat 6 to move horizontally. After the decorative panel is cut, the first cutting blade 17 and the second cutting blade 18 are slightly lifted. Then the linear drive rail drives the guide seat 6 to move away from the conveyor table 1. The guide seat 6 drives the first cutting blade 17 and the second cutting blade 18 to move, scraping the cut decorative panel edge material outwards and removing it from the cutting table 4. This prevents cutting waste from accumulating on the cutting table 4, keeping the cutting table 4 clean and facilitating continuous operation.

[0060] The working principle of this multi-angle decorative panel automatic cutting device is as follows: The adjustable roller assembly on the conveyor table 1 slides and holds the conveyed decorative panel, preventing it from moving or shifting. A laser displacement sensor 9 monitors the panel position in real time. When the panel reaches the cutting position, the adjustment mechanism is activated: an electric push rod 26 pushes the first high-precision motor 21 and the electrically controlled suction cup 28 downwards, causing the suction cup 28 to adhere and fix to the surface of the decorative panel. A second electric telescopic rod 24 extends and retracts, pushing the first high-precision motor 21 and the suction cup 28 laterally. The suction cup 28 moves the decorative panel closer to or further away from the first cutting blade 17 and the second cutting blade 18, adjusting the cutting position. Furthermore, the second high-precision motor 27 drives the suction cup 28 and the decorative panel to rotate, adjusting their angles to ensure proper alignment or allow for cutting within a wider angle range. Simultaneously, the two sets of cutting components on the guide seat 6 work in tandem: the initial state is preset to the most commonly used angles, with the first cutting blade 17 at 45° and the second cutting blade 18 at 145°, reducing angle switching time by 65%.

[0061] In actual processing, the intelligent algorithm of the control host automatically allocates cutting tasks. When the first cutting blade 17 performs acute-angle cutting, it can simultaneously perform obtuse-angle cutting. Parallel operation halves the processing time of the standard plate. The first adjusting seat 15 drives the first cutting blade 17 downward via the telescopic cylinder 19, and the first high-precision motor 21 adjusts the blade to the required angle of 0-90° via the gear ring 20 mechanism. The second adjusting seat 16 simultaneously adjusts the second cutting blade 18 to the range of 91-180°. An angle encoder ensures a positioning accuracy of ±0.03°. After cutting, the linear drive guide rail moves the guide seat 6, and the blade scrapes the waste material away from the cutting table 4. The distance between the two cutting blades is adjusted by the bidirectional threaded rod 32, allowing for independent operation to improve efficiency, or combined operation to achieve V-shaped splicing cutting. Throughout the process, an image recognition camera, in conjunction with the control host, achieves fully automated operation.

[0062] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
