Description

Technical Field

[0001] The invention relates to the technical field of thin wood board processing equipment, and in particular to a wood board processing turning mechanism and a use method thereof. Background Art

[0002] Veneer is a frequently used material in home decoration. Veneer is a thin wood board made of complete wood. These boards are strong and durable, with natural grain, and are the best choice in decoration. This type of board is expensive. Veneer is generally classified according to the actual name of the board, and there is no unified standard specification. The board processing flipping mechanism is a device used in the processing of wood or veneer. Its main function is to flip the veneer for processing at different angles or completing multi-sided processing.

[0003] Among them, when flipping the veneer, in order to ensure the smoothness of the flipping, the veneer often needs to be clamped. The common clamping method usually uses a clamping block to clamp the veneer. However, when clamping a thinner veneer, a large clamping force may easily cause the veneer to deform, and a small clamping force may easily cause the veneer to shake, affecting the stability of the flipping of the veneer. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a wood board processing flipping mechanism, comprising a support table, a flipping block is rotatably connected to the inner wall of the support table, a motor is fixedly connected to the side wall of the support table, an output end of the motor at the side wall is fixedly connected to the side wall of the flipping block, three electric telescopic rods are fixedly connected to the bottom of the flipping block, and a blocking component is arranged on the top of the flipping block;

[0005] A supporting mechanism, the supporting mechanism comprising a thin wood board, a supporting frame for supporting the thin wood board, a conveying wheel, and an adsorption component for limiting and clamping the thin wood board;

[0006] There are two support frames, and the bottoms of the two support frames are fixedly connected to the top of the flip block. There are eight conveying wheels, and the eight conveying wheels are arranged in a group of four. The inner walls of the two support frames are rotatably connected to the outer walls of the two groups of conveying wheels. The bottom of the veneer board is placed on the outer wall of the eight conveying wheels, and the veneer board is conveyed by the conveyor until the veneer board contacts the conveying wheels, and the veneer board is moved to the top of the support frame by the conveying wheels. Then the electric telescopic rod is started to extend, pushing the fixed frame to rise, driving the blocking plate 1 to rise. Since the fixed plate is in a stationary state, when the fixed plate rises, the blocking plate 1 will be separated from the fixed plate. At this time, the through hole and the suction cup are misaligned, so the bottom of the fixed plate is in a closed state. When the blocking plate 1 is separated from the fixed plate, negative pressure will be generated at the bottom of the blocking plate 1. As the fixed frame continues to rise, the suction cup will contact the bottom of the veneer board, so that the suction cup and the veneer board fit together. At this time, the arc block will also be connected to the connecting rod The camber block is pressed against the suction cup and the spring return rod is moved to the suction cup to absorb the bottom of the veneer. At the same time, the movement of the camber plate drives the spring return rod to move, so that the spring return rod accumulates rebound force. After the veneer is absorbed and clamped, the motor is started to drive the flip block to rotate 180° counterclockwise, so that the flip block rotates to the top of another conveyor, and then the electric telescopic rod is retracted to cancel the absorption of the veneer, so that the veneer falls on another conveyor and the flipping of the veneer is completed. After that, the motor drives the flip block to rotate 180° clockwise to return the flip block to its original position. By adsorbing and clamping the veneer, the veneer is subjected to a flexible clamping force, which effectively prevents uneven clamping force from causing deformation or shaking of the veneer, thereby ensuring the stability of the flipping process of the veneer.

[0013] Preferably, the blocking assembly also includes two connecting frames arranged on the top of the flip block, three spring return rods three are fixedly connected to the side walls of the two connecting frames, the outer walls of the six spring return rods three are slidably connected to the inner walls of the six fixed frames, the side walls of the six spring return rods three are rotatably connected to rollers, and the inner walls of the two connecting frames are rotatably connected to blocking rollers. When the inclined block descends, the inclined surface of the inclined block will contact the rollers, thereby pushing the rollers to move toward the supporting frame, driving the spring return rods three and the connecting frames to move, allowing the spring return rods three to accumulate rebound force, and when the connecting frames move, they will drive the blocking rollers to move to the top of the veneer to block the veneer.

[0014] Preferably, the dust removal assembly includes three air collecting grooves opened on the inner wall of the flip block, the inner walls of the three air collecting grooves are slidably connected with extrusion plates, six connecting plates are arranged in groups of three, the tops of the left and right extrusion plates are fixedly connected to the bottoms of the two groups of connecting plates, and the bottoms of the three extrusion plates are fixedly connected with five push rods;

[0015] Among them, fifteen air inlet holes are opened at the bottom of the flip block, and the outer walls of the fifteen push rods are slidably connected with the inner walls of the fifteen air inlet holes. A pressing assembly is provided at the bottom of the flip block. When the connecting plate descends, the extrusion plate and the push rod will be driven to descend. When the push rod moves into the air inlet, the air inlet will be blocked. At this time, the inside of the gas collecting tank is in a sealed state, and the extrusion plate will squeeze the gas in the gas collecting tank when it descends, and the pressure of the squeezed gas will increase.

[0016] Preferably, the dust removal assembly further comprises a blocking plate 2 slidably connected to the inner wall of the gas collecting tank, three U-shaped rods are fixedly connected to the bottom of the right extrusion plate, the tops of the three U-shaped rods are fixedly connected to the bottom of the extrusion plate at the center, and fifteen spring rods are fixedly connected to the bottoms of the three blocking plates 2;

After the blocking plate two drops, the high-pressure gas will enter the jet tube and be sprayed toward the bottom of the thin wooden board through the jet tube to clean the contact surface between the thin wooden board and the suction cup.

[0019] Among them, the outer walls of forty-five piston rods are slidably connected with the inner walls of forty-five spring rods, and fifteen connecting grooves are opened on the inner walls of the three blocking plates. When the flip block flips 180°, the connecting frame will be located on the top of the flip block, and the counterweight block in the connecting frame will drop due to the influence of its own weight, thereby squeezing the gas in the connecting frame. At this time, the squeezed gas will be blocked by the piston rod, so the gas pressure will increase. At the same time, when the counterweight block moves, it will also drive the piston rod to move. When the piston rod moves to the position of the connecting groove, a gap will leak between the piston rod and the connecting groove, and the high-pressure gas will enter the jet pipe from the connecting groove.

[0020] A method for using a wood board processing turning mechanism comprises the following steps:

[0021] S1: Wood board conveying: conveying the veneer wood board through the conveyor until the veneer wood board contacts the conveying wheel, and the veneer wood board is moved to the top of the support frame through the conveying wheel;

[0022] S2: clamping the board: start the electric telescopic rod to extend, push the fixed frame to rise, and drive the blocking plate 1 to rise. Since the fixed plate is in a stationary state, when the fixed plate rises, the blocking plate 1 will be separated from the fixed plate, so that negative pressure is generated at the bottom of the blocking plate 1. As the fixed frame continues to rise, the suction cup will contact the bottom of the thin wooden board, fit with the thin wooden board, and absorb and clamp the bottom of the thin wooden board;

[0023] S3: flipping of the board: start the motor to drive the flipping block to rotate 180° counterclockwise, let the flipping block rotate to the top of another conveyor, then retract the electric telescopic rod to cancel the adsorption of the thin board, so that the thin board falls on another conveyor, completing the flipping of the thin board.

[0024] The present invention has the following beneficial effects:

[0025] (1) When the present invention is used, the veneer is conveyed by the conveyor until the veneer contacts the conveying wheel, and the veneer is moved to the top of the support frame by the conveying wheel, and then the electric telescopic rod is started to extend, pushing the fixed frame to rise, driving the blocking plate 1 to rise. Since the fixed plate is in a stationary state, when the fixed plate rises, the blocking plate 1 will be separated from the fixed plate. At this time, the through hole and the suction cup are misaligned, so the bottom of the fixed plate is in a closed state. When the blocking plate 1 is separated from the fixed plate, negative pressure will be generated at the bottom of the blocking plate 1. As the fixed frame continues to rise, the suction cup will contact the bottom of the veneer, so that the suction cup and the veneer are fitted together. At this time, the arc block will also contact the connecting rod. Since the contact surface of the arc block and the connecting rod are both arc surfaces, the fixed frame continues to move, and the arc block will squeeze the connecting rod away from the suction cup. , driving the blocking plate to move, the through hole will be connected with the suction cup, so that the negative pressure will be transmitted to the suction cup to adsorb the bottom of the veneer. At the same time, the movement of the blocking plate will drive the spring return rod to move, so that the spring return rod will accumulate resilience. After the adsorption and clamping of the veneer is completed, the motor is started to drive the flip block to rotate 180° counterclockwise, so that the flip block rotates to the top of another conveyor, and then the electric telescopic rod is retracted to cancel the adsorption of the veneer, so that the veneer falls on another conveyor, completing the flipping of the veneer. After that, the motor drives the flip block to rotate 180° clockwise to return the flip block. Through the adsorption and clamping of the veneer, the veneer is subjected to a flexible clamping force, which effectively prevents uneven clamping force from causing deformation or shaking of the veneer, thereby ensuring the stability of the flipping process of the veneer.

[0026] (2) When the fixed frames on the left and right sides of the present invention rise, they will also drive the connecting blocks to rise, allowing the connecting blocks to contact the seesaw and push the seesaw to rotate, so that the side of the seesaw close to the connecting block rises and the other side falls. The fallen side of the seesaw will contact the connecting plate, thereby pushing the connecting plate to fall, driving the spring return rod 2 and the inclined plane block to fall, so that the spring return rod 2 accumulates a rebound force. When the inclined plane block falls, the inclined surface of the inclined plane block will contact the roller, thereby pushing the roller to move toward the support frame, driving the spring return rod 3 and the connecting frame to move, so that the spring return rod 3 accumulates a rebound force. When the connecting frame moves, it will drive the blocking roller to move to the top of the veneer board to block the veneer board. When the suction cup contacts the veneer board, it will push the veneer board to rise. The veneer board is blocked by the blocking roller, and the suction cup can fully contact the veneer board, allowing the suction cup to stably adsorb the veneer board, effectively preventing the formation of a gap between the suction cup and the veneer board, which affects the stability of negative pressure adsorption.

[0027] (3) When the connecting plate of the present invention descends, it will drive the extrusion plate and the push rod to descend. When the push rod moves to the air inlet, it will block the air inlet. At this time, the interior of the gas collecting tank is in a sealed state. The extrusion plate descends and squeezes the gas in the gas collecting tank. The pressure of the squeezed gas will increase. As the push rod continues to move, the push rod will contact the second blocking plate, push the second blocking plate down, squeeze the spring rod, and allow the spring rod to accumulate rebound force. After the second blocking plate descends, the high-pressure gas will enter the jet pipe and be sprayed toward the bottom of the veneer through the jet pipe to clean the contact surface between the veneer and the suction cup, effectively preventing the presence of more dust on the bottom of the veneer, which may cause the fitting effect between the suction cup and the bottom of the veneer to deteriorate, thereby deteriorating the adsorption performance.

[0028] (4) In the present invention, when the flip block flips 180°, the connection frame will be located on the top of the flip block, and the counterweight block in the connection frame will drop due to its own weight, thereby squeezing the gas in the connection frame. At this time, the squeezed gas will be blocked by the piston rod, so the gas pressure will increase. At the same time, when the counterweight block moves, it will also drive the piston rod to move. When the piston rod moves to the position of the connecting groove, a gap will leak out between the piston rod and the connecting groove, and the high-pressure gas will enter the jet pipe from the connecting groove and spray toward the contact surface of the suction cup and the thin wooden board. At this time, the electric telescopic rod will drive the fixed frame back to its original position, and the gas spray will facilitate breaking the vacuum, so that the suction cup can be quickly separated from the thin wooden board.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0042] For example, see Figure 1 - Figure 5 The present invention is a wood board processing flipping mechanism, comprising a support table 1, a flipping block 11 is rotatably connected to the inner wall of the support table 1, a motor 12 is fixedly connected to the side wall of the support table 1, an output end of the motor 12 at the side wall is fixedly connected to the side wall of the flipping block 11, three electric telescopic rods 13 are fixedly connected to the bottom of the flipping block 11, and a blocking component 4 is arranged on the top of the flipping block 11;

[0043] The supporting mechanism 2 includes a thin wood board 23, a supporting frame 21 for supporting the thin wood board 23, a conveying wheel 22, and an adsorption component 3 for limiting and clamping the thin wood board 23;

[0044] There are two support frames 21, the bottoms of the two support frames 21 are fixedly connected to the top of the flip block 11, there are eight conveying wheels 22, and the eight conveying wheels 22 are arranged in a group of four. The inner walls of the two support frames 21 are rotatably connected to the outer walls of the two groups of conveying wheels 22. The bottom of the veneer 23 is placed on the outer wall of the eight conveying wheels 22, and the veneer 23 is conveyed by the conveyor until the veneer 23 contacts the conveying wheels 22, and the veneer 23 is moved to the top of the support frame 21 by the conveying wheels 22, and then the electric telescopic rod 13 is started to extend to push the fixed The frame 31 rises, driving the blocking plate 1 33 to rise. Since the fixed plate 32 is in a stationary state, when the fixed plate 32 rises, the blocking plate 1 33 will be separated from the fixed plate 32. At this time, the through hole 34 and the suction cup 35 are misaligned, so the bottom of the fixed plate 32 is in a closed state. When the blocking plate 1 33 is separated from the fixed plate 32, negative pressure will be generated at the bottom of the blocking plate 1 33. As the fixed frame 31 continues to rise, the suction cup 35 will contact the bottom of the thin board 23, so that the suction cup 35 and the thin board 23 are fitted. At this time, the arc block 321 will also be connected to the The rod 331 contacts, and since the contact surfaces of the arc block 321 and the connecting rod 331 are both arc surfaces, the fixed frame 31 continues to move, and the arc block 321 will squeeze the connecting rod 331 away from the suction cup 35, driving the blocking plate 1 33 to move, so that the through hole 34 is connected to the suction cup 35, so that the negative pressure is transmitted to the suction cup 35, and the bottom of the thin board 23 is adsorbed. At the same time, the movement of the blocking plate 1 33 will drive the spring return rod 1 36 to move, so that the spring return rod 1 36 accumulates resilience. After the thin board 23 is adsorbed and clamped, the flip block is driven by starting the motor 12 11 rotates 180° counterclockwise to allow the flip block 11 to rotate to the top of another conveyor, and then retracts the electric telescopic rod 13 to cancel the adsorption of the veneer 23, so that the veneer 23 falls on another conveyor to complete the flipping of the veneer 23, and then the motor 12 drives the flip block 11 to rotate 180° clockwise to allow the flip block 11 to return to its original position. By adsorbing and clamping the veneer 23, the veneer 23 is subjected to a flexible clamping force, which effectively prevents uneven clamping force from causing deformation or shaking of the veneer 23, thereby ensuring the stability of the flipping process of the veneer 23.

At the same time, when the counterweight block 62 moves, it will also drive the piston rod 63 to move. When the piston rod 63 moves to the position of the connecting groove 64, a gap will leak between the piston rod 63 and the connecting groove 64, and the high-pressure gas will enter the injection pipe 57 from the connecting groove 64.

[0058] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0059] The method for using the wood board processing flipping mechanism includes the following steps:

[0060] S1: conveying the wood board: conveying the thin wood board 23 by the conveyor until the thin wood board 23 contacts the conveying wheel 22, and the thin wood board 23 is moved to the top of the support frame 21 by the conveying wheel 22;

[0061] S2: clamping the board: start the electric telescopic rod 13 to extend, push the fixed frame 31 to rise, and drive the blocking plate 1 33 to rise. Since the fixed plate 32 is in a stationary state, when the fixed plate 32 rises, the blocking plate 1 33 will be separated from the fixed plate 32, so that negative pressure is generated at the bottom of the blocking plate 1 33. As the fixed frame 31 continues to rise, the suction cup 35 will contact the bottom of the thin board 23, fit with the thin board 23, and absorb and clamp the bottom of the thin board 23;

[0062] S3: flipping of the board: starting the motor 12 to drive the flipping block 11 to rotate 180° counterclockwise, allowing the flipping block 11 to rotate to the top of another conveyor, and then retracting the electric telescopic rod 13 to cancel the adsorption of the thin board 23, so that the thin board 23 falls on another conveyor, completing the flipping of the thin board 23.

[0063] A specific application of this embodiment is as follows: when the present invention is used, the veneer board 23 is conveyed by the conveyor until the veneer board 23 contacts the conveying wheel 22, and the veneer board 23 is moved to the top of the support frame 21 by the conveying wheel 22, and then the electric telescopic rod 13 is started to extend, pushing the fixed frame 31 to rise, driving the blocking plate 1 33 to rise, and since the fixed plate 32 is in a stationary state, when the fixed plate 32 rises, the blocking plate 1 33 will be separated from the fixed plate 32, at this time, the through hole 34 and the suction cup 3 5 is misaligned, so the bottom of the fixing plate 32 is in a closed state. When the blocking plate 1 33 is separated from the fixing plate 32, negative pressure will be generated at the bottom of the blocking plate 1 33. As the fixing frame 31 continues to rise, the suction cup 35 will contact the bottom of the thin board 23, so that the suction cup 35 and the thin board 23 are fitted. At this time, the arc block 321 will also contact the connecting rod 331. Since the contact surfaces of the arc block 321 and the connecting rod 331 are both arc surfaces, the fixing frame 31 continues to move, and the arc block 32 1 will squeeze the connecting rod 331 away from the suction cup 35, drive the blocking plate 13 to move, and make the through hole 34 communicate with the suction cup 35, so that the negative pressure is transmitted to the suction cup 35, and the bottom of the thin board 23 is adsorbed. At the same time, the movement of the blocking plate 13 will drive the spring return rod 136 to move, so that the spring return rod 136 accumulates the resilience. After the thin board 23 is adsorbed and clamped, the flip block 11 is driven by the starting motor 12 to rotate 180° counterclockwise, so that the flip block 11 rotates to the other side. The electric telescopic rod 13 is retracted to cancel the adsorption of the veneer 23, so that the veneer 23 falls on another conveyor, and the veneer 23 is turned over. Then the motor 12 drives the turning block 11 to rotate 180° clockwise, and the turning block 11 returns to its original position. By adsorbing and clamping the veneer 23, the veneer 23 is subjected to a flexible clamping force, which effectively prevents uneven clamping force from causing deformation or shaking of the veneer 23, thereby ensuring the stability of the turning process of the veneer 23.

[0064] Secondly, when the fixed frames 31 on the left and right sides rise, the connecting blocks 42 will also be driven to rise, so that the connecting blocks 42 will contact the seesaw 43, and the seesaw 43 will be pushed to rotate, so that the side of the seesaw 43 close to the connecting block 42 will rise, and the other side will fall. The side of the seesaw 43 that falls will contact the connecting plate 44, thereby pushing the connecting plate 44 to fall, driving the spring return rod 441 and the inclined block 45 to fall, so that the spring return rod 441 accumulates resilience, and when the inclined block 45 falls, the inclined surface of the inclined block 45 will contact the roller 462, thereby pushing the roller 462 toward the support When the connecting frame 46 moves in the direction of the thin board 23, the spring return rod 3 461 and the connecting frame 46 are driven to move, so that the spring return rod 3 461 accumulates a rebound force. When the connecting frame 46 moves, it drives the blocking roller 47 to move to the top of the thin board 23 to block the thin board 23. When the suction cup 35 contacts the thin board 23, the thin board 23 is pushed up. The thin board 23 is blocked by the blocking roller 47, and the suction cup 35 can fully contact with the thin board 23, so that the suction cup 35 can stably adsorb the thin board 23, effectively preventing a gap between the suction cup 35 and the thin board 23, which affects the stability of negative pressure adsorption.

[0065] When the connecting block 42 pushes the seesaw 43 to rotate, the rotation amplitude of the seesaw 43 will increase and the contact area with the connecting block 42 will decrease. When the suction cup 35 completes the adsorption of the thin wood board 23, the connecting block 42 will separate from the seesaw 43. At this time, the rebound force of the spring return rod 2 441 will be released, so that the inclined block 45 returns to its original position and separates from the roller 462. The rebound force of the spring return rod 3 461 will also be released, so that the connecting frame 46 and the blocking roller 47 return to their original positions, canceling the blocking of the thin wood board 23, so that the thin wood board 23 can fall smoothly after being turned over.

[0066] Secondly, when the connecting plate 44 descends, the squeezing plate 52 and the pushing rod 53 will be driven to descend. When the pushing rod 53 moves into the air inlet 55, the air inlet 55 will be blocked. At this time, the interior of the gas collecting groove 51 is in a sealed state. The squeezing plate 52 descends and squeezes the gas in the gas collecting groove 51. The pressure of the squeezed gas will increase. As the pushing rod 53 continues to move, the pushing rod 53 will contact the second blocking plate 56, push the second blocking plate 56 down, squeeze the spring rod 561, and let the spring rod 561 accumulate resilience. After the second blocking plate 56 descends, the high-pressure gas will enter the jet pipe 57 and be sprayed toward the bottom of the veneer 23 through the jet pipe 57 to clean the contact surface between the veneer 23 and the suction cup 35, effectively preventing the bottom of the veneer 23 from having a lot of dust, which may cause the suction cup 35 to have a poor fit with the bottom of the veneer 23 and make the adsorption poor.

[0067] When the connecting plate 44 returns to its original position, the squeezing plate 52 and the pushing rod 53 also return to their original position, so that the air inlet 55 is connected to the inside of the gas collecting tank 51 again, and the gas inside the gas collecting tank 51 is replenished. At the same time, when the squeezing plate 52 on the right side descends, the squeezing plate 52 at the center is driven to descend by the U-shaped rod 54.

[0068] Secondly, when the flip block 11 flips 180°, the connecting frame 61 will be located at the top of the flip block 11, and the counterweight block 62 in the connecting frame 61 will drop due to its own weight, thereby squeezing the gas in the connecting frame 61. At this time, the squeezed gas will be blocked by the piston rod 63, so the gas pressure will increase. At the same time, when the counterweight block 62 moves, it will also drive the piston rod 63 to move. When the piston rod 63 moves to the position of the connecting groove 64, a gap will leak between the piston rod 63 and the connecting groove 64, and the high-pressure gas will enter the jet pipe 57 from the connecting groove 64 and spray toward the contact surface of the suction cup 35 and the thin wooden board 23. At this time, the electric telescopic rod 13 will drive the fixed frame 31 to return to its position, and the gas spray will facilitate breaking the vacuum, so that the suction cup 35 can be quickly separated from the thin wooden board 23.
