Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Embodiment: Refer to Figures 1 to 10, A fixed-length cutting device for wood processing boards, including a cutting table main body 1. The cutting table main body 1 includes a workbench 11. A vertical baffle 12 is fixed at the upper end of the workbench 11. The vertical baffle 12 forms a right angle with the workbench 11, and the vertical baffle 12 is made of metal with a relatively smooth surface. When the components in the clamping mechanism 2 drive the board to move, there will be no large frictional force between the surface of the vertical baffle 12 and the board. A support frame 13 is fixed at the upper end of the vertical baffle 12. A hydraulic telescopic tube 14 is fixed at the upper end of the support frame 13. The telescopic end of the hydraulic telescopic tube 14 penetrates through the upper end of the support frame 13 and is fixed with a lower pressing plate 15. When the device cuts the board, the hydraulic telescopic tube 14 therein will drive the lower pressing plate 15 to move downward, so that the lower pressing plate 15 can limit the board from above, and the board will not be displaced during the cutting process;

[0036] Then, a blanking groove 16 is opened at the upper end of the workbench 11 on the side close to the cutting mechanism 3. A triangular plate 17 is fixed on the inner wall of the blanking groove 16 close to the lower pressing plate 15. The cut board will fall downward from the blanking groove 16. A support plate 18 is fixed inside the workbench 11. A rack plate 19 is fixed at the end of the support plate 18 away from the lower pressing plate 15. A fixed-length limit plate 10 is slidably connected to the upper end of the workbench 11. There are scales on the upper end of the workbench 11. By adjusting the position of the fixed-length limit plate 10 through the scales, the length of the board to be cut can be determined. The fixed-length limit plate 10 is located above the blanking groove 16. The clamping mechanism 2 and the cutting mechanism 3 are fixed inside the cutting table main body 1;

[0037] It should be noted that through the mutual cooperation of the cutting table main body 1 and the clamping mechanism 2, the accessories in the clamping mechanism 2 and the vertical baffle 12 clamp the board. At the same time, the accessories in the clamping mechanism 2 can also drive the board to move on the workbench 11. Then, the components in the cutting mechanism 3 cut the board, and at the same time collect the cut board to achieve the purpose of automatic blanking.

[0038] Furthermore, in order to be able to limit the board and drive it to move, the following settings are made, such as Figure 4 and Figure 5As shown, the clamping mechanism 2 includes a cylinder 21 fixed to the main body 1 of the cutting table. A base 22 is fixed to the telescopic end of the cylinder 21. Three clamping rollers 23 are rotatably arranged at the upper end of the base 22. By starting the three clamping rollers 23 to move through the cylinder 21, the wooden board can be limited by the vertical baffle 12 and the clamping rollers 23, so that it will not shift during cutting. A driving component 24 driven indirectly is arranged in the two clamping rollers 23 far away from the cylinder 21. A communicating pipe 25 is fixed to the lower end of the driving component 24. A communicating ring 26 is sleeved on the outer surface of the communicating pipe 25. Two meshing bevel gears 27 are arranged below the communicating pipe 25. One end of the lower bevel gear 27 is fixed with a hydraulic telescopic sleeve. A first motor 28 is fixed to the lower end of the base 22. The output end of the first motor 28 is connected to the two communicating pipes 25 by belt drive.

[0039] For further explanation, in order to drive the wooden board to move through the clamping roller 23, the following settings are made, as Figure 6 As shown, the driving component 24 includes a support shell 241 rotatably connected to the upper end of the base 22. Open slots 242 are symmetrically formed on the arc surface of the support shell 241. A sealing shell 243 is fixed inside the support shell 241. Rectangular shells 244 are symmetrically fixed to the arc surface of the sealing shell 243. T-shaped plates 245 are hermetically slid in the rectangular shells 244. A plurality of through holes 246 are symmetrically formed on the inner wall of the sealing shell 243. The communicating pipe 25 is connected to the sealing shell 243 and the hydraulic telescopic sleeve. A two-way pumping device is arranged between the communicating pipe 25 and the hydraulic telescopic pipe 14. When hydraulic oil enters the sealing shell 243, the impact force generated by its flow will push the T-shaped plates 245 to move away from each other. After moving a certain distance, they will contact the inner wall of the clamping roller 23. Under the action of friction, the T-shaped plates 245 can drive the clamping roller 23 to rotate;

[0040] It should be noted that the hydraulic telescopic pipe 14 and the hydraulic telescopic sleeve form a complete cavity, and the two sealing shells 243 form another complete cavity through the communicating pipe 25. The two-way pumping device can make the hydraulic oil flow in the two cavities. When the wooden board needs to move, the two-way pumping device will pump the hydraulic oil out of the hydraulic telescopic pipe 14 and the hydraulic telescopic sleeve, and then pump it into the two sealing shells 243. When the wooden board needs to be cut, the two-way pumping device will pump the hydraulic oil out of the two sealing shells 243, and then pump it into the hydraulic telescopic pipe 14 and the hydraulic telescopic sleeve;

[0041] Specifically, start the two-way pumping device to pump hydraulic oil into the connecting pipe 25. The hydraulic oil entering the connecting pipe 25 will enter the sealing shell 243, then enter the rectangular shell 244 through the through hole 246, and push the T-shaped plate 245 to move away from each other by the impact force of the flowing hydraulic oil until the T-shaped plate 245 contacts the inner wall of the driving assembly 24. Then start the first motor 28 to drive the support shell 241 to rotate through the connecting pipe 25. The T-shaped plate 245 located in the rectangular shell 244 will also rotate with the support shell 241. Under the action of friction, the T-shaped plate 245 will drive the driving assembly 24 to rotate, enabling the wooden board to move towards the cutting component.

[0042] For further illustration, in order to complete the cutting work and blanking work of the wooden board, the following settings are made, as Figure 7 and Figure 8 shown, the cutting mechanism 3 includes a reciprocating lead screw 31 rotating on the inner top wall of the workbench 11. A reciprocating frame 32 is sleeved on the surface of the reciprocating lead screw 31. When the reciprocating lead screw 31 rotates, it can drive the reciprocating frame 32 sleeved on its surface to reciprocate. A second motor 33 is fixed to the lower end of the reciprocating frame 32. A limiting groove 35 is opened at the upper end of the workbench 11. The output end of the second motor 33 is fixed with a cutting circular saw 34. The second motor 33 can drive the cutting circular saw 34 to rotate rapidly and move with the reciprocating frame 32, so as to cut the wooden board. The cutting circular saw 34 is located in the limiting groove 35. The lower end of the reciprocating lead screw 31 is fixed with a blanking component 36. The blanking component 36 will collect the wooden boards falling from the blanking groove 16. An adjusting component 37 is fixed to the end face of the workbench 11 away from the lower pressing plate 15. The adjusting component 37 can adjust the rotation speed of the reciprocating lead screw 31. When the device cuts multiple wooden boards at a time, the thickness of the wooden boards will be very large. In order to ensure the cutting effect of the cutting circular saw 34, the cutting circular saw 34 needs to move slowly. When cutting a single wooden board, for the processing efficiency, the cutting circular saw 34 can have a faster moving speed.

[0043] For further illustration, in order to enable the device to have the function of automatic blanking, the following settings are made, as Figure 9 shown, the blanking component 36 includes a material collecting box body 361 fixed to the lower end of the reciprocating frame 32. A plurality of square grooves 362 are symmetrically opened on the vertical end face of the material collecting box body 361. One end of the material collecting box body 361 close to the rack plate 19 is connected with a driving gear one 363 in a one-way rotating manner. A one-way bearing is arranged at the shaft of the driving gear one 363. When the driving gear one 363 moves towards the rack plate 19, the rack plate 19 will drive the driving gear one 363 to rotate. However, due to the one-way bearing, the driving gear one 363 cannot drive the pulley to rotate. That is to say, the driving gear one 363 cannot drive the driving gear two 364 to rotate;

[0044] Then, when the first transmission gear 363 moves in the reverse direction, the first transmission gear 363 drives the second transmission gear 364 to rotate, causing the second transmission gear 364 to drive the rack frame 365 and the top plate 366 to move downward. The first transmission gear 363 meshes with or disengages from the rack plate 19. A second transmission gear 364 is provided on one side of the first transmission gear 363. A rack frame 365 is meshed on one side of the second transmission gear 364. A top plate 366 is provided in the material receiving box body 361, and the top plate 366 is fixedly connected to the rack frame 365;

[0045] It should be noted that the material receiving box body 361 moves along with the reciprocating frame 32, causing the first transmission gear 363 to move towards the direction close to the rack plate 19. When the first transmission gear 363 contacts the rack plate 19, it will enter the meshing state. However, under the action of the one-way bearing, the first transmission gear 363 will not drive the second transmission gear 364 to rotate until the cut wooden board falls from the triangular plate 17 and the blanking groove 16 onto the top plate 366 in the material receiving box body 361, achieving the purpose of automatic blanking. The continuously rotating reciprocating screw rod 31 drives the reciprocating frame 32 to move in the reverse direction. At this time, the engaged rack plate 19 drives the first transmission gear 363 to rotate, and the first transmission gear 363 drives the second transmission gear 364 to rotate, causing the rack frame 365 that remains engaged with it to drive the top plate 366 to move downward for collecting the subsequent cut wooden boards.

[0046] Further explanation, in order to cut multiple wooden boards smoothly, the following settings are made, such as Figure 10 As shown, the adjusting assembly 37 includes an adjusting shell 371 fixed to one end of the workbench 11. Conical rollers 372 are symmetrically and rotatably connected inside the adjusting shell 371. A driving rod adapted to the hydraulic telescopic sleeve is fixed to the vertical end face of the conical roller 372 closer to the workbench 11. The conical roller 372 farther from the workbench 11 is belt-driven by the air cylinder 21. A support block 373 is provided between the two conical rollers 372. U-shaped blocks 374 are elastically connected to both side faces of the support block 373. A transmission rod 375 is rotatably connected inside the U-shaped block 374. The two transmission rods 375 are attached to the surfaces of the two conical rollers 372. When one of the conical rollers 372 rotates, the two transmission rods 375 can be driven to rotate through friction;

[0047] Then, and according to the different circumferences of each position of the conical roller 372, when the support block 373 fits on different positions of the two conical rollers 372, the rotational speed of the other conical roller 372 driven by the transmission rod 375 will change. An adjusting rod 376 is slidably connected inside the adjusting shell 371. An adjusting knob 377 is slidably connected inside the adjusting rod 376. An adjusting block 378 adapted to the U-shaped block 374 is fixed to the lower end of the adjusting knob 377;

[0048] It should be noted that the adjustment knob 377 can be pressed downward to drive the adjustment block 378 to move downward. During the movement of the adjustment block 378, it will push the two U-shaped blocks 374 to drive the transmission rods 375 to move away from each other, so that the two transmission rods 375 no longer fit on the surface of the tapered roller 372, and the position where the two transmission rods 375 fit on the surface of the tapered roller 372 can be adjusted. At the same time, when cutting multiple wooden boards, it is necessary to drive the two transmission rods 375 to move towards the wooden board by adjusting the knob 377 and the support block 373, so as to reduce the rotation speed of the reciprocating lead screw 31.

[0049] The working principle of the present invention is as follows: Place the wooden board to be cut on the workbench 11, start the cylinder 21 to push the base 22 and the clamping roller 23 fixed thereon towards the wooden board. The clamping roller 23 will first contact the wooden board, and then push the wooden board to move until it contacts the vertical baffle 12 until the wooden board cannot move. Adjust the position of the fixed-length limit plate 10 through the scale on the workbench 11 to limit the length of the cut wooden board.

[0050] Start the two-way pumping device to pump hydraulic oil into the connecting pipe 25. The hydraulic oil entering the connecting pipe 25 will enter the sealing shell 243, and then enter the rectangular shell 244 through the through hole 246. The impact force of the flowing hydraulic oil will push the T-shaped plate 245 to move away from each other until the T-shaped plate 245 contacts the inner wall of the drive assembly 24. Then start the first motor 28 to drive the support shell 241 to rotate through the connecting pipe 25. The T-shaped plate 245 located in the rectangular shell 244 will also rotate with the support shell 241. Under the action of friction, the T-shaped plate 245 will drive the drive assembly 24 to rotate, and move the wooden board after the clamping work is completed towards the cutting circular saw 34 until the wooden board contacts the fixed-length limit plate 10 and cannot move.

[0051] Start the two-way pumping device again to reverse-extract the hydraulic oil in the support shell 241, so that the hydraulic oil enters the hydraulic telescopic pipe 14 and the hydraulic telescopic sleeve. At the same time, the T-shaped plate 245 will reset and cannot drive the drive assembly 24 to rotate. The hydraulic oil entering the hydraulic telescopic pipe 14 will push the lower pressing plate 15 downward to press the wooden board, and the hydraulic oil entering the hydraulic telescopic sleeve will drive the sleeve to extend so that it sleeves on the surface of the drive rod. The bevel gear 27 can drive the drive rod to rotate through the hydraulic telescopic sleeve.

[0052] The driving rod will drive the conical roller 372 on the same side to rotate, and then drive the two transmission rods 375 attached to the surface of the conical roller 372. The two transmission rods 375 will drive the conical roller 372 on the other side to rotate. Through the transmission of the two conical rollers 372 and the transmission rods 375, the reciprocating lead screw 31 belt-drivenly connected to the conical roller 372 rotates. During the rotation of the reciprocating lead screw 31, it will drive the reciprocating frame 32 and the cutting circular saw 34 to move along the limiting groove 35 towards the wooden board. At this time, starting the second motor 33 will drive the cutting circular saw 34 to rotate rapidly. When the cutting circular saw 34 contacts the wooden board, it will perform the cutting work on the wooden board. The material receiving box body 361 will move along with the reciprocating frame 32, so that the first transmission gear 363 will move towards the direction close to the rack plate 19. When the first transmission gear 363 contacts the rack plate 19, it will become in a meshing state. However, under the action of the one-way bearing, the first transmission gear 363 will not drive the second transmission gear 364 to rotate until the cut wooden board falls from the triangular plate 17 and the blanking groove 16 onto the top plate 366 in the material receiving box body 361, achieving the purpose of automatic blanking. The continuously rotating reciprocating lead screw 31 will drive the reciprocating frame 32 to move in the reverse direction. At this time, the mutually meshing rack plate 19 will drive the first transmission gear 363 to rotate, and the first transmission gear 363 will drive the second transmission gear 364 to rotate, so that the rack frame 365 that remains meshed with it drives the top plate 366 to move downward to collect the subsequently cut wooden boards;

[0053] To ensure the stability when cutting wooden boards, when cutting a thicker template or cutting multiple wooden boards simultaneously, the adjustment knob 377 can be pressed downward to drive the adjustment block 378 to move downward. During the movement of the adjustment block 378, it will push the two U-shaped blocks 374 to drive the transmission rods 375 to move away from each other, so that the two transmission rods 375 no longer adhere to the surface of the conical roller 372, and the position where the two transmission rods 375 adhere to the surface of the conical roller 372 can be adjusted. When cutting multiple wooden boards simultaneously, it is necessary to drive the two transmission rods 375 to move towards the wooden board through the adjustment knob 377 and the support block 373, so as to reduce the rotation speed of the reciprocating lead screw 31 and ensure that the cutting circular saw 34 can smoothly complete the cutting work.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
