DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0030] The present invention will be further described below in conjunction with the embodiments.

[0031] Example: Refer to Figures 1 to 10, a device for cutting a wooden board to a fixed length for wood processing, comprising a cutting table body 1, the cutting table body 1 comprising a working table 11, a vertical baffle 12 is fixed to the upper end of the working table 11, the vertical baffle 12 and the working table 11 maintain a right angle, and the vertical baffle 12 is made of metal with a relatively smooth surface, when the components in the clamping mechanism 2 drive the wooden board to move, the surface of the vertical baffle 12 will not generate a large friction force with the wooden board, a support frame 13 is fixed to the upper end of the vertical baffle 12, a hydraulic telescopic tube 14 is fixed to the upper end of the support frame 13, the telescopic end of the hydraulic telescopic tube 14 passes through the upper end of the support frame 13 and is fixed with a lower pressing plate 15, when the device cuts the wooden board, the hydraulic telescopic tube 14 will drive the lower pressing plate 15 to move downward, so that the lower pressing plate 15 can limit the position of the wooden board from above, and the wooden board will not be displaced during the cutting process; Then, a material discharge chute 16 is provided at the upper end of the workbench 11 near the cutting mechanism 3, and a triangular plate 17 is fixed to the inner wall of the material discharge chute 16 near the lower pressing plate 15. The wood board after cutting will fall downward from the material discharge chute 16, and a support plate 18 is fixed in the workbench 11. A rack plate 19 is fixed to 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. A scale is provided at the upper end of the workbench 11. By adjusting the position of the fixed-length limit plate 10 by the scale, the length of the wood board to be cut can be fixed. The fixed-length limit plate 10 is located above the material discharge chute 16, and the clamping mechanism 2 and the cutting mechanism 3 are fixed in the cutting table body 1; It should be noted that, through the mutual cooperation of the cutting table body 1 and the clamping mechanism 2, the accessories in the clamping mechanism 2 and the vertical baffle 12 clamp the wooden board, and the accessories in the clamping mechanism 2 can also drive the wooden board to move on the workbench 11, and then the components in the cutting mechanism 3 are used to cut the wooden board, and at the same time, the cut wooden board is collected to achieve the purpose of automatic unloading.

[0032] Further explanation, in order to limit the position of the wooden board and drive it to move, the following settings are made, such as Figure 4 and Figure 5 As shown, the clamping mechanism 2 includes a cylinder 21 fixed on the cutting table body 1, a base 22 is fixed to the telescopic end of the cylinder 21, and three clamping rollers 23 are rotatably arranged on the upper end of the base 22. By starting the movement of the three clamping rollers 23 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 deviate during cutting. An indirectly driven driving assembly 24 is arranged in the two clamping rollers 23 away from the cylinder 21, a connecting pipe 25 is fixed to the lower end of the driving assembly 24, a connecting ring 26 is sleeved on the outer surface of the connecting pipe 25, two mutually meshing bevel gears 27 are arranged below the connecting pipe 25, a hydraulic telescopic sleeve is fixed to one end of the bevel gear 27 located below, a motor 28 is fixed to the lower end of the base 22, and the output end of the motor 28 is connected to the two connecting pipes 25 by belt drive.

[0033] To further explain, in order to be able to drive the wooden board to move through the clamping roller 23, the following settings are made, such as Figure 6 As shown, the driving assembly 24 includes a supporting shell 241 rotatably connected to the upper end of the base 22, the arc surface of the supporting shell 241 is symmetrically provided with an opening groove 242, a sealing shell 243 is fixed inside the supporting shell 241, a rectangular shell 244 is symmetrically fixed on the arc surface of the sealing shell 243, a T-shaped plate 245 is airtightly slid inside the rectangular shell 244, a plurality of through holes 246 are symmetrically provided on the inner wall of the sealing shell 243, a connecting pipe 25 is connected with the sealing shell 243 and the hydraulic telescopic sleeve, a two-way pumping device is provided between the connecting pipe 25 and the hydraulic telescopic pipe 14, when the hydraulic oil enters the sealing shell 243, the impact force generated by its flow will push the T-shaped plate 245 to move away from each other, and after moving a certain distance, it will contact the inner wall of the clamping roller 23, and under the action of friction, the T-shaped plate 245 can drive the clamping roller 23 to rotate; It should be noted that the hydraulic telescopic tube 14 and the hydraulic telescopic sleeve form a complete cavity, and the two sealed shells 243 form another complete cavity through the connecting tube 25. The hydraulic oil can flow in the two cavities through the bidirectional pumping device. When the wooden board needs to be moved, the bidirectional pumping device will extract the hydraulic oil from the hydraulic telescopic tube 14 and the hydraulic telescopic sleeve, and then pump it into the two sealed shells 243. When the wooden board needs to be cut, the bidirectional pumping device will extract the hydraulic oil from the two sealed shells 243, and then pump it into the hydraulic telescopic tube 14 and the hydraulic telescopic sleeve. Specifically, the bidirectional pumping device is started 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 flow of hydraulic oil pushes the T-shaped plate 245 to move away from each other until the T-shaped plate 245 contacts the inner wall of the driving assembly 24. Then, the motor 28 is started to drive the supporting 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 supporting shell 241. Under the action of friction, the T-shaped plate 245 will drive the driving assembly 24 to rotate, so that the wooden board can move in the direction of the cut part.

[0034] Further explanation, in order to complete the cutting and unloading of the wood board, the following settings are made, such as Figure 7 and Figure 8As shown, the cutting mechanism 3 includes a reciprocating screw rod 31 rotating on the top wall of the workbench 11, and a reciprocating frame 32 is sleeved on the surface of the reciprocating screw rod 31. When the reciprocating screw rod 31 rotates, it can drive the reciprocating frame 32 sleeved on its surface to reciprocate. A motor 2 33 is fixed to the lower end of the reciprocating frame 32. A limiting groove 35 is provided at the upper end of the workbench 11. A cutting circular saw 34 is fixed to the output end of the motor 2 33. The cutting circular saw 34 can be driven by the motor 2 33 to rotate quickly, and it will move with the reciprocating frame 32, so that the wooden board can be cut. The cutting circular saw 34 is positioned at the upper end of the workbench 11. In the limiting groove 35, a feeding assembly 36 is fixed to the lower end of the reciprocating screw rod 31, and the feeding assembly 36 will collect the wooden boards dropped from the feeding chute 16. An adjusting assembly 37 is fixed to the end surface of the workbench 11 away from the lower pressure plate 15, and the rotation speed of the reciprocating screw rod 31 can be adjusted by the adjusting assembly 37. 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 processing efficiency, the cutting circular saw 34 can have a faster moving speed.

[0035] To further explain, in order to enable the device to have the function of automatic unloading, the following settings are made, such as Fig. 9 As shown, the material unloading assembly 36 includes a material receiving box 361 fixed to the lower end of the reciprocating frame 32, and a plurality of square grooves 362 are symmetrically opened on the vertical end surface of the material receiving box 361. One end of the material receiving box 361 close to the rack plate 19 is unidirectionally connected to a transmission gear 1 363, and a one-way bearing is provided at the shaft of the transmission gear 1 363. When the transmission gear 1 363 moves toward the rack plate 19, the rack plate 19 will drive the transmission gear 1 363 to rotate, but due to the one-way bearing, the transmission gear 1 363 cannot drive the pulley to rotate, that is, the transmission gear 1 363 cannot drive the transmission gear 2 364 to rotate; Then, when the transmission gear 1 363 moves in the reverse direction, the transmission gear 1 363 will drive the transmission gear 2 364 to rotate, so that the transmission gear 2 364 drives the rack frame 365 and the top plate 366 to move downward, and the transmission gear 1 363 is engaged with or separated from the rack plate 19. A transmission gear 2 364 is provided on one side of the transmission gear 1 363, and a rack frame 365 is engaged on one side of the transmission gear 2 364. A top plate 366 is provided in the material receiving box 361, and the top plate 366 is fixedly connected to the rack frame 365. It should be noted that the material receiving box 361 will move with the reciprocating frame 32, so that the transmission gear 1 363 will move in the direction close to the rack plate 19, and when the transmission gear 1 363 contacts the rack plate 19, it will become meshing state, but under the action of the one-way bearing, the transmission gear 1 363 will not drive the transmission gear 2 364 to rotate until the cut wooden board falls from the triangular plate 17 and the unloading chute 16 to the top plate 366 in the material receiving box 361, completing the purpose of automatic unloading, and the reciprocating screw rod 31 that continues to rotate will drive the reciprocating frame 32 to move in the opposite direction. At this time, the rack plate 19 that is in meshing with each other will drive the transmission gear 1 363 to rotate, and the transmission gear 1 363 will drive the transmission gear 2 364 to rotate, so that the rack frame 365 that is meshing with it drives the top plate 366 to move downward, so as to collect the subsequently cut wooden boards.

[0036] Further explanation, in order to be able to smoothly cut multiple wooden boards, the following settings are made, such as Fig.10 As shown, the adjustment assembly 37 includes an adjustment shell 371 fixed to one end of the workbench 11, and a conical roller 372 is symmetrically rotatably connected in the adjustment shell 371. A driving rod adapted to the hydraulic telescopic sleeve is fixed to the vertical end face of the conical roller 372 close to the workbench 11, and the conical roller 372 away from the workbench 11 is connected to the cylinder 21 with a transmission. A support block 373 is provided between the two conical rollers 372, and U-shaped blocks 374 are elastically connected to the two side surfaces of the support block 373. A transmission rod 375 is rotatably connected in the U-shaped block 374, and 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 by friction. Then, according to the different circumferences of the tapered rollers 372 at different positions, when the support block 373 is attached to different positions of the two tapered rollers 372, the rotation speed of the other tapered roller 372 driven by the transmission rod 375 will change, and an adjusting rod 376 is slidably connected in the adjusting shell 371, and an adjusting knob 377 is slidably connected in the adjusting rod 376, and an adjusting block 378 adapted to the U-shaped block 374 is fixed to the lower end of the adjusting knob 377; 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, the two U-shaped blocks 374 will drive the transmission rod 375 to move away from each other, so that the two transmission rods 375 no longer fit the surface of the conical roller 372. The position of the two transmission rods 375 fitting on the surface of the conical roller 372 can be adjusted. When cutting multiple wooden boards at the same time, it is necessary to drive the two transmission rods 375 to move towards the direction close to the wooden boards through the adjustment knob 377 and the support block 373 to reduce the rotation speed of the reciprocating screw 31.

[0037] The working principle of the present invention is as follows: the board to be cut is placed on the workbench 11, and the cylinder 21 is started to push the base 22 and the clamping roller 23 fixed thereon to move toward the board. The clamping roller 23 will first contact the board, and then push the board to move so that it contacts the vertical baffle 12 until the board cannot move. The position of the fixed-length limit plate 10 is adjusted by the scale on the workbench 11 to limit the length of the cut board. The two-way pumping device is started 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 flow of hydraulic oil pushes the T-shaped plate 245 to move away from each other until the T-shaped plate 245 contacts the inner wall of the driving assembly 24. Then, the motor 28 is started to drive the supporting 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 supporting shell 241. Under the action of friction, the T-shaped plate 245 will drive the driving assembly 24 to rotate, and move the wooden board after the clamping work to the direction of the cutting circular saw 34 until the wooden board contacts the fixed-length limit plate 10 and cannot move. The bidirectional pumping device is started again to reversely extract the hydraulic oil in the support shell 241, so that the hydraulic oil enters the hydraulic telescopic tube 14 and the hydraulic telescopic sleeve. At the same time, the T-shaped plate 245 will be reset and cannot drive the driving assembly 24 to rotate. The hydraulic oil entering the hydraulic telescopic tube 14 will push the lower pressure plate 15 to move downward to pressurize the wooden board, and the hydraulic oil entering the hydraulic telescopic sleeve will drive the sleeve to extend so that it is sleeved on the surface of the driving rod, and the bevel gear 27 can drive the driving rod to rotate through the hydraulic telescopic sleeve. 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. The transmission of the two conical rollers 372 and the transmission rod 375 will cause the reciprocating screw rod 31 connected to the conical roller 372 to rotate. During the rotation, the reciprocating screw rod 31 will drive the reciprocating frame 32 and the cutting circular saw 34 to move along the limiting groove 35 toward the direction of the wooden board. At this time, starting the motor 2 33 will drive the cutting circular saw 34 to rotate quickly. When the cutting circular saw 34 contacts the wooden board, it will cut the wooden board. The material receiving box 361 will move with the reciprocating frame 32, causing the transmission gear 1 363 to rotate. It moves in the direction close to the rack plate 19, and when the transmission gear 1 363 contacts the rack plate 19, it will become meshed. However, under the action of the one-way bearing, the transmission gear 1 363 will not drive the transmission gear 2 364 to rotate until the cut wooden board falls from the triangular plate 17 and the unloading chute 16 to the top plate 366 in the receiving box 361, completing the purpose of automatic unloading. The reciprocating screw rod 31 that continues to rotate will drive the reciprocating frame 32 to move in the opposite direction. At this time, the rack plate 19 that is in meshing with each other will drive the transmission gear 1 363 to rotate, and the transmission gear 1 363 will drive the transmission gear 2 364 to rotate, so that the rack frame 365 that is meshed with it drives the top plate 366 to move downward, so as to collect the subsequently cut wooden boards. In order to ensure stability when cutting wooden boards, when cutting thicker templates or cutting multiple wooden boards at the same time, the adjusting knob 377 can be pressed downward to drive the adjusting block 378 to move downward. During the movement of the adjusting block 378, the two U-shaped blocks 374 will drive the transmission rod 375 to move away from each other, so that the two transmission rods 375 no longer fit the surface of the conical roller 372. The position of the two transmission rods 375 fitting on the surface of the conical roller 372 can be adjusted. When cutting multiple wooden boards at the same time, it is necessary to drive the two transmission rods 375 to move towards the direction close to the wooden board through the adjusting knob 377 and the support block 373, so that the rotation speed of the reciprocating screw rod 31 is reduced to ensure that the cutting circular saw 34 can smoothly complete the cutting work.
