When the present invention is in use, the plate to be processed is put into the material barrel. At this time, the propulsion motor drives the propulsion rod to rotate to push the plate forward step by step. After the plate is pushed forward by a unit distance and stops, the reduction motor drives the gear disk to rotate through the reduction gear, and the torsion turntable and the central rod and torsion vertical rod on its top also rotate 90 degrees following the gear disk, and the plate will be continuously bent twice to form the required furniture parts.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figure 1-12 , the present invention provides a technical solution, including:

[0045] The equipment housing 1 is provided with a first driving component inside for driving the wooden board 3 to move upward and perform a bending operation. The first driving component includes two hydraulic rods 203 hinged at both ends of the bottom of the inner wall of the equipment housing 1. The top of the output shaft of the hydraulic rod 203 is hinged with a movable frame 201. One end of the opposite surfaces of the two movable frames 201 is respectively fixedly installed with a rotating tube 206. The inner wall of the rotating tube 206 is rotatably connected with a positioning rod 207, and the positioning rod 207 is fixedly installed on the inner wall of the equipment housing 1. The inner wall of the movable frame 201 is fixedly installed with a driving rod 204. The surface of the driving rod 204 is fixedly installed with a hinged rod 205, and the top of the hinged rod 205 is rotatably connected with a bending frame 202. A torsion spring is provided between the hinged rod 205 and the bending frame 202 so that the included angle between the hinged rod 205 and the bending frame 202 can be restored to the initial state. The wooden board 3 is movably connected to the top of the bending frame 202;

[0046] When the above structure is in use, first place the wooden board 3 on the top of the bending frame 202. At this time, the first driving component starts to work. Among them, the first driving component starts to work, and the working principle of the first driving component is similar to that of a solid wood bending equipment provided by the patent publication number CN214871313U. By stretching the hydraulic rod 203 and driving the movable frame 201 to rotate around the rotating tube 206 and the positioning rod 207, the movable frame 201 drives the bending frame 202 to move upward and deviate through the driving rod 204 and the hinged rod 205, so as to tightly press the wooden board 3 on the surface of the plastic metal soft board 410, thereby completing the bending operation.

[0047] A first driving component is arranged at the top of the device housing 1, and the first driving component is used to adjust the curvature of the bending of the wood board 3. The first driving component includes a first positioning plate 401 movably connected to one end of the device housing 1, and a second positioning plate 402 is hinged to the other end of the device housing 1 far from the first positioning plate 401 through a hinge seat. A plastic metal soft plate 410 with a variable diameter is movably arranged between the first positioning plate 401 and the second positioning plate 402, so that the plastic metal soft plate 410 can change the curvature of the wood board 3 that is closely attached to the plastic metal soft plate 410. The middle part of the first positioning plate 401 is rotatably connected to a driving shaft 403 through a bearing. A first driving disk 404 is fixedly installed on the surface of the driving shaft 403. A second driving disk 405 is rotatably connected to the surface of the driving shaft 403. A plurality of movable rods 406 are movably arranged in the middle of the second driving disk 405. A driving column 407 is fixedly installed in the middle of the movable rod 406 corresponding to the second driving disk 405. A driving groove 408 is formed in the middle of the first driving disk 404 corresponding to the driving column 407, and the driving column 407 is movably connected to the inner wall of the driving groove 408. The driving groove 408 is an arc-shaped structure, so that when the first driving disk 404 drives the driving groove 408 to rotate, the driving column 407 will move on the inner wall of the driving groove 408. A support frame 501 is fixedly installed at the top of one of the movable rods 406. The other ends of the remaining movable rods 406 far from the second driving disk 405 are all fixedly installed with movable plates 409, and the movable plates 409 are located at one ends of two adjacent movable rods 406 in the front and back. The bottom of the movable plate 409 at the bottom is fixedly installed in the middle of the inner wall of the plastic metal soft plate 410, and the surfaces of the remaining movable plates 409 are all movably connected to the inner wall of the plastic metal soft plate 410. The number of the second driving disks 405 and the first driving disks 404 are both two, and the two second driving disks 405 are symmetrically arranged about the vertical axis of the midpoint of the device housing 1. A guiding groove 416 for providing a moving space for the movable rod 406 and the driving column 407 is formed in the middle of the second driving disk 405 corresponding to the movable rod 406, and the driving column 407 and the movable rod 406 are both movably connected to the inner wall of the guiding groove 416. The guiding groove 416 movably penetrates and extends to one end of the first driving disk 404, so that the driving column 407 can be movably connected to the inner wall of the driving groove 408. The number of the movable rods 406 is six, and the six movable rods 406 are arranged in a ring in the middle of the second driving disk 405;

[0048] When the above structure is in use, the first driving disk 404 is driven to rotate by the driving shaft 403. Since the driving groove 408 is an arc-shaped structure, when the first driving disk 404 rotates, the driving groove 408 will drive the driving column 407 to move along the radial direction. Furthermore, the driving column 407 cooperates with the movable rod 406 to drive the movable plate 409 and the support frame 501 to move equidistantly along the radial direction, thereby changing the diameter of the circle where the surfaces of the plurality of movable plates 409 are located, that is, changing the diameter of the plastic metal flexible plate 410, so as to achieve the purpose of being able to change the curvature of the wood board 3 as needed.

[0049] A limiting flexible belt 411 is movably connected to the surface of the plastic metal flexible plate 410. The limiting flexible belt 411 is a strip-shaped structure with a hollow middle, and the limiting flexible belt 411 fits on the surface of the plastic metal flexible plate 410. Limiting grooves are provided at both ends of the limiting flexible belt 411, and limiting ridges are respectively provided at both ends of the surface of the plastic metal flexible plate 410. The limiting ridges are movably connected to the inner wall of the limiting groove, so that the limiting flexible belt 411 limits the plastic metal flexible plate 410 through the cooperation of the limiting ridges and the limiting grooves to prevent the plastic metal flexible plate 410 from running off. Connecting plates 412 are fixedly installed at the tops of both ends of the limiting flexible belt 411. Fixed plates 413 are fixedly installed at one ends of the opposite surfaces of the first positioning plate 401 and the second positioning plate 402 corresponding to the positions of the connecting plates 412. The fixed plates 413 are located at the bottoms of the connecting plates 412. A telescopic rod 414 is fixedly installed at one end of the opposite surfaces of the connecting plate 412 and the fixed plate 413. A damping spring 415 is fixedly installed on the surface of the telescopic rod 414. A plurality of connecting rods 417 are fixedly installed at one ends of the opposite surfaces of the two second driving disks 405. A guiding shaft 9 for guiding the limiting flexible belt 411 is fixedly installed at one end of the opposite surfaces of the first positioning plate 401 and the second positioning plate 402, and the guiding shaft 9 is closely attached to the surface of the limiting flexible belt 411. A handle 8 is fixedly installed at one end of the first positioning plate 401 away from the second positioning plate 402;

[0050] When the above structure is in use, by setting the limiting flexible belt 411, and the limiting flexible belt 411 cooperates with the limiting ridges at both ends of the plastic metal flexible plate 410 through the limiting grooves at both ends, the plastic metal flexible plate 410 can be prevented from separating from the limiting flexible belt 411. At the same time, when the diameter of the plastic metal flexible plate 410 changes, it will cause the limiting flexible belt 411 to drive the connecting plate 412 to move downward, and cause relative movement between the connecting plate 412 and the fixed plate 413, thereby squeezing the telescopic rod 414 and the damping spring 415. Under the action of the elastic force of the damping spring 415, the limiting flexible belt 411 will tightly bundle the plastic metal flexible plate 410 to prevent the plastic metal flexible plate 410 from separating from the movable plate 409 and causing the wood board 3 to bend and produce defects.

[0051] A grinding component is movably arranged inside the driving component, and the grinding component is used to grind the inner arc surface of the wood board 3 after the driving component completes the bending of the wood board 3. The grinding component includes a grinding belt 503 that is transmission-arranged inside the shaping metal soft plate 410, and the plane where the top of the grinding belt 503 is located is tangent to the curved surface where the shaping metal soft plate 410 is located, so that the grinding belt 503 can grind the inner arc surface of the wood board 3. The middle parts of the two support frames 501 are rotatably connected to the grinding roller 502, and the grinding belt 503 is rotatably connected to the grinding roller 502.

At this time, the grinding roller 502 drives the adjusting roller 601 to move through the grinding belt 503 and the driving roller 504. Then, the adjusting roller 601 drives the movable seat 602 to move on the inner wall of the guiding frame 603 and compress the adjusting spring 604, so that the grinding belt 503 can change accordingly with the change of the diameter of the plastic metal soft plate 410, and the grinding belt 503 can always grind the inner arc surface of the wood board 3.

Then, the worm 704 drives the driving shaft 403 to rotate through the worm gear 703. A fixing frame 709 is fixedly installed at one end of the second positioning plate 402, and a servo motor 707 is fixedly installed in the middle of the inner wall of the fixing frame 709. A driving gear 708 is fixedly installed on the surface of the output shaft of the servo motor 707, and the surface of the driving gear 708 is engaged with the surface of the gear disk 702;

[0056] When the above structure is in use, by using tools such as a wrench, it extends into the interior of the gear disk 702 from the operation slot and drives the driving block 705 to rotate, so that the driving block 705 drives the worm 704 to rotate, and further the worm 704 drives the worm gear 703 to rotate. And when the worm gear 703 rotates, it will make the worm gear 703 drive the driving shaft 403 to rotate, thereby changing the diameter of the plastic metal soft plate 410. At the same time, the servo motor 707 is energized to drive the driving gear 708 to rotate, and further the driving gear 708 drives the gear disk 702 to rotate, and the gear disk 702 drives the second driving disk 405 to rotate through the driving cover 701. Under the fixed installation action of the connecting rod 417, the two connecting rods 417 rotate synchronously. At the same time, the gear disk 702 also drives the driving shaft 403 and the second driving disk 405 to rotate synchronously through the cooperation of the worm gear 703 and the worm 704, thereby driving the plastic metal soft plate 410, the second driving disk 405 and the grinding belt 503 to rotate synchronously, ensuring that the grinding belt 503 can complete the grinding of the inner arc surface of the wood board 3.

[0057] Working principle: When in use, the present invention first places the wood board 3 on the top of the bending frame 202. At this time, the driving assembly starts to work. When the driving assembly starts to work, the hydraulic rod 203 stretches and drives the movable frame 201 to rotate around the rotating tube 206 and the positioning rod 207. Then the movable frame 201 drives the bending frame 202 to move upward and offset through the driving rod 204 and the hinge rod 205, so as to tightly press the wood board 3 on the surface of the plastic metal soft plate 410, thus completing the bending operation.

[0058] When it is necessary to adjust the curvature of the bent wooden board 3, by using tools such as a wrench, insert it into the inside of the gear disk 702 from the operation slot, and drive the driving block 705 to rotate, so that the driving block 705 drives the worm 704 to rotate, and then the worm 704 drives the worm wheel 703 to rotate. When the worm wheel 703 rotates, the worm wheel 703 drives the driving shaft 403 to rotate. When the driving shaft 403 rotates, the driving shaft 403 drives the first driving disk 404 to rotate. Since the driving slot 408 is an arc-shaped structure, when the first driving disk 404 rotates, the driving slot 408 drives the driving column 407 to move along the radial direction, and then the driving column 407 cooperates with the movable rod 406 to drive the movable plate 409 and the support frame 501 to move equidistantly along the radial direction, thereby changing the diameter of the circle where the surfaces of the plurality of movable plates 409 are located, that is, changing the diameter of the plastic metal soft plate 410. At the same time, through the fixed installation of the middle part of the inner wall of the plastic metal soft plate 410 on the surface of the movable plate 409 at the bottom, the two ends of the plastic metal soft plate 410 will move evenly and change the diameter of the plastic metal soft plate 410 under the extrusion of the movable plates 409 at both ends, so as to achieve the purpose of changing the curvature of the wooden board 3 according to needs. By setting the plastic metal soft plate 410, it can also play a role in transitioning the gaps between the plurality of movable plates 409, preventing the movable plates 409 from directly contacting the wooden board 3, and preventing the gaps between the plurality of movable plates 409 from causing defects in the bending of the wooden board 3;

[0059] By setting the limiting soft belt 411, and the limiting soft belt 411 is matched with the limiting convex strips at both ends of the plastic metal soft plate 410 through the limiting grooves at both ends, it can prevent the plastic metal soft plate 410 from separating from the limiting soft belt 411. At the same time, when the diameter of the plastic metal soft plate 410 changes, the diameter of the plastic metal soft plate 410 will drive the diameter of the limiting soft belt 411 to change, and the limiting soft belt 411 will drive the connecting plate 412 to move downward, and the relative movement between the connecting plate 412 and the fixing plate 413 will squeeze the telescopic rod 414 and the damping spring 415. Under the action of the elastic force of the damping spring 415, the limiting soft belt 411 will tightly tighten the two ends of the plastic metal soft plate 410, so that the plastic metal soft plate 410 will tightly fit the surface of the movable plate 409. At the same time, by setting the guiding shaft 9, the limiting soft belt 411 can be guided, so that the limiting soft belt 411 can tightly bind the plastic metal soft plate 410, preventing the plastic metal soft plate 410 from separating from the movable plate 409 and causing defects in the bending of the wooden board 3;

[0060] When it is necessary to polish the inner arc surface of the wooden board 3, the servo motor 707 is energized to drive the driving gear 708 to rotate. Then, the driving gear 708 drives the tooth disc 702 to rotate, and the tooth disc 702 drives the second driving disc 405 to rotate through the driving cover 701. Under the fixed installation of the connecting rod 417, the two connecting rods 417 rotate synchronously. At the same time, the tooth disc 702 drives the driving shaft 403 and the second driving disc 405 to rotate synchronously through the worm gear 703 and the worm 704, that is, the movable rod 406 and the second driving disc 405 do not move relative to each other. When the second driving disc 405 rotates, the second driving disc 405 drives the movable plate 409 and the support frame 501 to rotate through the movable rod 406, that is, the notch at the top of the plastic metal soft plate 410 rotates with the rotation of the second driving disc 405. Since the plane where the top of the polishing belt 503 is located is tangent to the curved surface where the plastic metal soft plate 410 is located, when the notch of the plastic metal soft plate 410 rotates to the inner arc surface of the wooden board 3, the polishing belt 503 can be closely attached to the inner wall of the inner surface of the wooden board 3, so that the polishing belt 503 can polish the inner arc surface of the wooden board 3. At this time, the driving motor 505 is energized to drive the driving roller 504 to rotate, and then the driving roller 504 drives the polishing roller 502 to rotate, and the polishing roller 502 drives the polishing belt 503 to drive, so as to polish the inner wall of the inner arc surface of the wooden board 3. As the second driving disc 405 and the plastic metal soft plate 410 rotate on the inner arc surface of the bent wooden board 3, the polishing belt 503 can completely polish the inner arc surface of the wooden board 3, thus achieving the purpose of facilitating the quick and convenient polishing of the inner curved surface of the wooden board 3;

[0061] When the movable rod 406 moves along the radial direction of the second driving disc 405, the movable rod 406 drives the support frame 501 to move, and then the support frame 501 drives the polishing roller 502 to move along the radial direction of the second driving disc 405. At this time, the polishing roller 502 drives the adjusting roller 601 to move through the polishing belt 503 and the driving roller 504, and then the adjusting roller 601 drives the movable seat 602 to move on the inner wall of the guiding frame 603 and compress the adjusting spring 604, so that the polishing belt 503 can change accordingly with the change of the diameter of the plastic metal soft plate 410, so that the polishing belt 503 can always polish the inner arc surface of the wooden board 3;

[0062] In the initial state, the first positioning plate 401 and the equipment housing 1 are fixed by a lock. When the bending of the wooden board 3 is completed, the lock between the first positioning plate 401 and the equipment housing 1 is unlocked at this time, and the handle 8 is manually pushed upward, so that the handle 8 drives the second positioning plate 402 to be hinged to the equipment housing 1 through the first positioning plate 401 and the guiding shaft 9. At this time, the plastic metal soft plate 410 is set to be inclined upward, so as to facilitate the removal of the bent wooden board 3 located at the bottom of the plastic metal soft plate 410.
