The board seam produced after the wooden board body is cut will be scanned by the scanner to identify whether there are burrs or burrs in the board seam. Once burrs appear, it means that the cutting knife is not sharp enough. At this time, the motor and the motor are started synchronously to operate. The motor will drive the rotating rod and the sleeve plate to rotate synchronously at an angle of 30 degrees, and then drive the polishing disk to move upward and probe into the board seam.

Therefore, when the cutting knife moves back and forth up and down, the two sets of grinding discs will simultaneously rotate and grind the blade surfaces at both ends of the cutting knife to make it sharp again. In the process of the U-shaped groove plate moving up and down, the first thing to contact the surface of the cutting knife is the wire block, and the wood chips on its surface and the resin attached to it due to long-term work are first processed to ensure the grinding effect of the cutting knife.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 10 As shown, the present invention provides an automated wood board self-processing equipment, including an automatic cutting device 1, a left-right moving component 11 is fixedly connected to the outer wall of one end of the automatic cutting device 1, two auxiliary wheels are fixedly connected to the plate body of one end of the left-right moving component 11, an up-down lifting component 12 is provided on one side of the left-right moving component 11, a plurality of wood board bodies 13 are laminated on the top outer wall of the up-down lifting component 12, a front-back moving component 14 is fixedly connected to the automatic cutting device 1, a fence frame 1401 is slidably connected to the top of the front-back moving component 14, and an electric cylinder 1 is installed on the automatic cutting device 1. 5. A cutting knife 16 is fixedly connected to the bottom end of the electric cylinder 15, and a scanner 17 is also fixedly connected to the automatic cutting equipment 1. A polishing part 2 is provided on the outer wall of one side of the bottom end of the fence frame 1401. The polishing part 2 includes a support plate 21 fixedly connected to the outer wall of one side of the bottom end of the fence frame 1401. A forward and reverse rotating motor 22 is fixedly connected to the outer wall of one end of the support plate 21. A rotating rod 23 is fixedly connected to the rotating shaft of the motor 22. A sleeve plate 24 is fixedly connected to the rod body of the rotating rod 23, and the rod body of the rotating rod 23 is specifically connected to the support plate 21 for through-rotation. The sleeve plate 24 is provided with a polishing and grinding structure.

[0033] The above scheme is adopted: by starting the automatic cutting equipment 1, the front and rear moving assembly 14 installed on the automatic cutting equipment 1 can drive the upper panel frame 1401 to slide forward and backward, and then the push plate frame slidably connected to the top of the left and right moving assembly 11 will automatically push the board body 13 on the top of the upper and lower lifting assembly 12, and push it to the panel frame 1401 to wait for the cutting knife 16 to cut. When the board body 13 is passively pushed, it will pass through the two auxiliary wheels installed at one end of the left and right moving assembly 11 to reduce the friction resistance of pushing the board body 13. When the push plate frame is passively reset on the left and right moving assembly 11, the upper and lower lifting assembly 12 will automatically move up to a certain height, driving the board body 13 to move up synchronously, so that when the push plate frame moves horizontally again, the board body 13 can be continuously pushed. The operations of the left and right moving assembly 11, the upper and lower lifting assembly 12, and the front and rear moving assembly 14 are all set by the computer programming system in advance. They are all existing technologies and will not be described in detail here.

[0034] The polishing and grinding structure includes a motor 25 fixedly connected to the outer wall of one side of the bottom end of the sleeve plate 24, a guide rod 26 fixedly connected to the rotating shaft of the motor 25, the rod body of the guide rod 26 and the plate body of the sleeve plate 24 are connected in a through-rotation manner, the other end of the guide rod 26 is fixedly connected to the polishing disc 27, the outer wall of the sleeve plate 24 away from the polishing disc 27 is fixedly connected to the back plate 28, the top of the back plate 28 is fitted with a U-shaped groove plate 29, and a moving plate 230 is fixedly connected to the outer wall of one end of the U-shaped groove plate 29. The moving plate 230 T-shaped sliders 231 are fixedly connected to the two end plates on one side, and a rectangular groove is provided on the other end plate of the support plate 21. T-shaped sliding grooves 232 are provided in the inner walls at both ends of the rectangular groove to fit and slide with the two T-shaped sliders 231. Folding curtains 233 are fixedly connected to the upper and lower end plates of the movable plate 230. The other end of the upper folding curtain 233 is fixedly connected to the bottom outer wall of the guardrail frame 1401, and the other end of the lower folding curtain 233 is fixedly connected to the bottom inner wall of the rectangular groove.

[0035] The above scheme is adopted: the electric cylinder 15 is started to drive the cutting knife 16 to move up and down reciprocatingly, thereby cutting the wooden board body 13. The board seam produced after the wooden board body 13 is cut will be scanned by the scanner 17 to identify whether there are burrs or burrs in the board seam. Once burrs appear, it means that the blade of the cutting knife 16 is not sharp enough. At this time, the motor 22 and the motor 25 are started synchronously. The motor 22 will drive the rotating rod 23 and the sleeve plate 24 to rotate synchronously at a rotation angle of 30 degrees, thereby driving the polishing disk 27 to move upward and probe into the board seam. The guide rod 26 and the polishing disk 27 driven by the motor 25 rotate at a high speed, thereby polishing the inner walls of the two ends of the board seam to remove burrs or burrs in the wooden board body 13;

[0036] After the board seams of the entire cutting surface of the wooden board body 13 are polished, the motor 22 will immediately drive the sleeve plate 24 to rotate in the opposite direction, thereby synchronously and passively tilting the support plate 28 to push up the U-shaped groove plate 29, driving the U-shaped groove plate 29 and the moving plate 230 to move upward. The passively moving upward moving plate 230 will pass through the T-shaped sliders 231 installed at both ends, and move upward in a limited manner in the two T-shaped slide grooves 232 in the support plate 21. The upward movement of the moving plate 230 will squeeze the upper folding curtain 233 and stretch the lower folding curtain 233.

[0037] The inner walls of both ends of the U-shaped groove plate 29 near the top are fixedly connected with wire blocks 234, and the other ends of the two wire blocks 234 can be intermittently fitted and slidably connected to the outer walls of the two ends of the cutting knife 16, and the U-shaped groove plate 29 is close to the polishing disc 27. Both ends are connected with multiple toothed discs 235 that are fitted and rotatably connected. One end of the two sets of toothed discs 235 is fixedly connected with a sleeve rod 237, and the rod bodies of the two sets of sleeve rods 237 are respectively movably sleeved with the inner wall plates at both ends of the U-shaped groove plate 29. The rod bodies of the two sets of sleeve rods 237 are also fixedly connected with grinding discs 238, and one end of the two sets of grinding discs 238 is respectively sleeved with the inner wall plates at both ends of the U-shaped groove plate 29. The two sets of grinding discs 238 are respectively connected to the outer walls of the two ends of the cutting knife 16 in a fitting and rotating manner. A set of symmetrically arranged tooth plates 239 are also fixedly connected to the plate body of the guardrail frame 1401. A set of tooth plates 239 can be intermittently meshed with the outer walls of the two sets of tooth plates 235. The inner walls of the two ends of the guardrail frame 1401 near the top are fixedly connected with top plates. A protective folding plate is respectively fixedly connected between the bottom ends of the two top plates and the two side plates on the top end of the U-shaped groove plate 29. The inner walls of the two protective folding plates are respectively connected to the outer walls of the two tooth plates 239 in a fitting and sliding manner.

[0038] The above scheme is adopted: the passively upward-moving U-shaped groove plate 29 will make the multiple toothed discs 235 contact the surface of the toothed plate 239 in turn when passing through the toothed plate 239. The meshing force generated by the contact between the two will cause the toothed disc 235 to rotate, and the rotation of the toothed disc 235 will drive the sleeve rod 237 and the grinding disc 238 to rotate synchronously. Therefore, when the cutting knife 16 moves up and down, it will repeatedly contact the up and down reciprocating translation of the U-shaped groove plate 29, and then the two sets of grinding discs 238 will simultaneously rotate and grind the blade surfaces of both ends of the cutting knife 16 to make it sharp again. In the process of the U-shaped groove plate 29 moving up, the wire block 234 first contacts the surface of the cutting knife 16, and the wood chips and resin attached to it due to long-term work on its surface are first processed to ensure the grinding effect of the cutting knife 16.

[0039] In the above-mentioned process of the U-shaped groove plate 29 moving upward, it will also synchronously drive the L-shaped protective folding plate to move upward in real time under the limit of the top plate, pressing and shrinking it, so as to prevent debris from getting stuck in the meshing position of the tooth plate 239 and the tooth disc 235, affecting the working state between the two. As a result, the upward movement of the limited space of the U-shaped groove plate 29 and the downward movement of the cutting knife 16 can be used to grind the blade surface of the cutting knife 16 in the opposite path. After the grinding disc 238 grinds the cutting knife 16, the cutting knife 16 may become thinner, so that the grinding disc 238 can no longer contact the cutting knife 16. However, if Figure 7 As shown, it can be seen that the grinding disc 238 is configured to be elastically retractable, so that it can contact the cutting blade 16 in real time.

[0040] The working principle and use process of the present invention are as follows: by starting the automatic cutting equipment 1, the front and rear moving component 14 installed on the automatic cutting equipment 1 can drive the upper panel frame 1401 to slide forward and backward, and then the push plate frame slidably connected to the top of the left and right moving component 11 will automatically push the wooden board body 13 on the top of the upper and lower lifting components 12, and push it to the panel frame 1401 to wait for the cutting knife 16 to cut. When the push plate frame is passively reset on the left and right moving component 11, the upper and lower lifting components 12 will automatically move up to a certain height, driving the wooden board body 13 to move up synchronously, so that the push plate frame moves horizontally again, and the wooden board body 13 can be continuously pushed, without the need to manually load the wooden boards one by one, thereby improving processing efficiency and reducing manual labor. Once the automatic cutting equipment 1 is started, the operations of the left and right moving components 11, the upper and lower lifting components 12, and the front and rear moving components 14 are all set by the computer programming system in advance, which are all existing technologies and will not be described in detail here.

[0041] When the wooden board body 13 is cut, the electric cylinder 15 needs to be started to drive the cutting knife 16 to move up and down reciprocatingly, thereby cutting the wooden board body 13. The board seam produced after the wooden board body 13 is cut will be scanned by the scanner 17 to identify whether there are burrs or burrs in the board seam. Once burrs appear, it means that the blade of the cutting knife 16 is not sharp enough. At this time, the motor 22 and the motor 25 are started synchronously. The motor 22 will drive the rotating rod 23 and the sleeve plate 24 to rotate synchronously at a rotation angle of 30 degrees, thereby driving the polishing disc 27 to move up and probe into the board seam. The guide rod 26 and the polishing disc 27 driven by the motor 25 rotate at high speed, thereby polishing the inner walls of the two ends of the board seam to remove burrs or burrs in the wooden board body 13.

[0042] After the board seam of the entire cutting surface of the wooden board body 13 is polished, the motor 22 will immediately drive the sleeve plate 24 to rotate in the opposite direction, thereby synchronously and passively tilting the abutment plate 28 to push the U-shaped groove plate 29, driving the U-shaped groove plate 29 and the shift plate 230 to move upward. The upward movement of the shift plate 230 will squeeze the upper folding curtain 233 and stretch the lower folding curtain 233. At the same time, the passively upward U-shaped groove plate 29 will make multiple toothed plates 235 contact the toothed plates in sequence when passing through the toothed plates 239. The meshing force generated by the contact between the two will cause the toothed disc 235, the sleeve rod 237 and the grinding disc 238 to rotate synchronously. Therefore, when the cutting knife 16 moves back and forth up and down, the two sets of grinding discs 238 will simultaneously rotate and grind the blade surfaces of the cutting knife 16 at both ends to make it sharp again. In the process of the U-shaped groove plate 29 moving upward, the first thing to contact the surface of the cutting knife 16 is the wire block 234, which first processes the wood chips on its surface and the resin attached to it due to long-term work.
