Technical Field

[0001] This invention relates to the field of wood processing equipment technology, and in particular to a board edge cleaning device and method. Background Technology

[0002] Wood planks are boards made from whole pieces of wood. These boards are sturdy, durable, and have natural grain, making them an excellent choice for interior design.

[0006] The beneficial effects of this invention are: the correction mechanism, together with the camera mechanism, the presser foot mechanism and the control mechanism, helps to fix and clean the plates with irregular edges in a way that minimizes the amount of plate cutting, thereby reducing the loss of individual plates and improving economic efficiency; at the same time, the control mechanism also helps to improve the automation level of the entire device and reduce manual intervention in the operation process.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the feeding mechanism includes: two chain conveyors, multiple limit blocks, multiple fixing frames, and a synchronous shaft. The multiple limit blocks are respectively disposed on the two chain conveyors, the multiple fixing frames are respectively installed on the two chain conveyors and connected to the first frame, and the two ends of the synchronous shaft are coaxially connected to the sprockets of the two chain conveyors near the second frame. The control mechanism is connected to the chain conveyors.

[0009] The beneficial effects of adopting the above-mentioned further solutions are: the chain conveyor is conducive to conveying the board to be cleaned, the limit block is conducive to pushing the board to be cleaned to move towards the bridge mechanism on the chain conveyor, the fixed frame is conducive to fixing the chain conveyor on the first frame, and the synchronous shaft is conducive to synchronizing the movement frequency of the two chain conveyors, thus preventing the board to be cleaned from shifting during transportation.

[0010] Furthermore, the second frame is provided with a first horizontal plate and a second horizontal plate in a direction perpendicular to the first frame. The first horizontal plate and the second horizontal plate are parallel and at the same height, and are each divided into three sections by a first partition space and a second partition space. The first horizontal plate is located on the side close to the first frame. The two rows of presser foot mechanisms correspond one-to-one with the first horizontal plate and the second horizontal plate, and the two unloading mechanisms correspond one-to-one with the first partition space and the second partition space.

[0011] The beneficial effects of adopting the above-mentioned further scheme are: the first and second horizontal plates are conducive to providing support for the presser foot mechanism to press the plate to be cleaned onto the second frame, and the first and second partition spaces are conducive to providing space for the unloading mechanism to hook out the plate that has been cleaned.

[0012] Furthermore, the bridge crossing mechanism includes: a first fixed bridge plate, two second fixed bridge plates, multiple movable bridge plates, multiple bridge plate cylinders, and a fixing rod. The two second fixed bridge plates are correspondingly arranged on both sides of the first fixed bridge plate. One end of the first fixed bridge plate and the two second fixed bridge plates are connected to the first frame, and the other end is correspondingly connected to the three sections of the first horizontal plate divided by the first partition space and the second partition space. The other end of the first fixed bridge plate and the second fixed bridge plate are hinged to the movable bridge plate. The multiple bridge plate cylinders are mounted on the first frame through the fixing rod. The output shafts of the multiple bridge plate cylinders are respectively hinged to the bottom surface of the multiple movable bridge plates. The two correction mechanisms are correspondingly arranged in the space between the first fixed bridge plate and the two second fixed bridge plates. The control mechanism is connected to the bridge plate cylinders.

[0013] The beneficial effects of adopting the above-mentioned further scheme are: the first fixed bridge plate and the two second fixed bridge plates provide space for the operation of the two correction mechanisms; the first fixed bridge plate and the two second fixed bridge plates are connected to the first frame and the second frame at the same time, which helps to improve the stability of the plate during movement; the movable bridge plate can be tilted up under the pushing action of the bridge plate cylinder, forming the same plane with the first fixed bridge plate and the two second fixed bridge plates, so that the plate after one side is cleaned can reach the second horizontal plate along the movable bridge plate, thereby achieving the pressing and cleaning of the other side of the plate.

[0014] Furthermore, the correction mechanism includes: a base, a correction slide rail, a correction slider, a correction motor, a lead screw, two supports, a crank arm, a lower pressure block and an upper pressure block of the correction cylinder; the base and the correction motor are both mounted on the first frame, the correction slide rail is disposed on the base, the correction slider is slidably mounted on the correction slide rail, the lead screw passes through the correction slider and is threadedly connected to the correction slider, the lead screw is connected to the output shaft of the correction motor, the supports are vertically disposed on one side of the top of the correction slider, and the correction cylinder is inclined. On the other side of the top of the correction slider, the crank arm is disposed between the two supports and hinged to the top of the supports. The output shaft of the correction cylinder is hinged to the top of the crank arm. The lower pressure block and the upper pressure block are disposed one-to-one at the top of the supports and the bottom of the crank arm. When the output shaft of the correction cylinder is pushed out, the plate to be cleaned is clamped between the lower pressure block and the upper pressure block. The top of the lower pressure block is flush with the top of the first fixed bridge plate and the second fixed bridge plate. The control mechanism is connected to the correction motor and the correction cylinder.

[0015] The beneficial effects of adopting the above-mentioned further scheme are: the correction slider is conducive to moving along the correction slide rail under the power of the correction motor, thereby driving the components installed on the correction slider to move. The separate movement of the two correction sliders is conducive to displacing the two sides of the plate to be cleaned by different distances, thereby adjusting the posture of the plate to be cleaned so that the side of the plate to be cleaned is parallel to the cutting mechanism; the correction cylinder is conducive to pushing the crank arm to rotate, thereby causing the lower pressure block and the upper pressure block to clamp the plate to be cleaned, improving the stability of the plate posture adjustment process.

[0016] Furthermore, the edge-cutting mechanism includes: a base plate, two displacement components, and two sawing components. The base plate is a plate-shaped structure with a strip-shaped through hole in the middle. The base plate is located at the top of the second frame. The two displacement components are correspondingly located at the top of the two sides of the strip-shaped through hole in the base plate. The two sawing components are correspondingly slidably connected to the two displacement components, pass through the strip-shaped through hole in the middle of the base plate, and are located between the first horizontal plate and the second horizontal plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the displacement component is conducive to driving the sawing component to move at the top of the second frame, thereby enabling the two sawing components to move separately to clean the two sides of the board.

[0018] Furthermore, the displacement assembly includes: a displacement power motor, a belt conveyor, two edge-cutting slide rails, a mounting plate, and multiple edge-cutting sliders. The multiple edge-cutting sliders are slidably disposed on the two edge-cutting slide rails respectively. The mounting plate is connected to the top of the edge-cutting sliders. The displacement power motor and the belt conveyor are disposed between the two edge-cutting slide rails. The output shaft of the displacement power motor is coaxially connected to the sprocket at one end of the belt conveyor. The mounting plate is fixedly connected to the belt of the belt conveyor.

[0019] The sawing assembly includes: a sawing power motor, two pulleys, a power transmission belt, and a saw blade cutter. The two pulleys are coaxially connected to the output shafts of the sawing power motor and the saw blade cutter, respectively. The two pulleys are connected to each other via the power transmission belt. The sawing power motor is mounted on the top of the mounting plate. The control mechanism is connected to the displacement power motor and the sawing power motor.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: the belt conveyor facilitates the movement of the mounting plate and the sawing components mounted on the mounting plate along the cutting edge guide rail, thereby improving the stability and reliability of the movement; the sawing power motor facilitates the transmission of power to the saw blade cutter through the pulley and power transmission belt, enabling the saw blade cutter to rotate at high speed to clean the edges of the board.

At one end, the unloading cylinder is connected to the lifting plate, and the output shaft is connected to the unloading slide plate. The torsion spring is provided on the bottom surface of the unloading slide plate near the second horizontal plate. The hook plate is hinged to the torsion spring. When the hook plate rotates to be perpendicular to the end of the unloading slide plate near the second horizontal plate, the hook plate protrudes upward from the top surface of the unloading slide plate, and the protrusion height is greater than the distance from the top surface of the unloading slide plate to the bottom surface of the fixed block. The hook plate is disposed between the first horizontal plate and the second horizontal plate. The control mechanism is connected to the unloading cylinder.

[0022] The beneficial effect of adopting the above-mentioned further solution is that it is beneficial to change the angle between the hook plate and the unloading slide plate by pushing out and retracting the unloading cylinder, thereby realizing the hooking of the plate that has been cleaned and hooking the cleaned plate out of the cleaning device.

[0023] Furthermore, the camera mechanism includes a camera bracket and multiple industrial cameras. The camera bracket is mounted on the top of the second frame, and the lenses of the multiple industrial cameras are mounted downwards and evenly on the camera bracket. The control mechanism is connected to the industrial cameras.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the industrial camera can take pictures of the board to be cleaned and transmit them to the control mechanism for data processing, thereby obtaining the two points with the least loss on the two sides of the board to be cleaned.

[0025] Another technical solution of the present invention to solve the above-mentioned technical problems is as follows: A method for cleaning the edges of a sheet metal, comprising the following steps:

[0026] S1: The feeding mechanism conveys the board to be cleaned to the area below the camera mechanism;

[0027] S2: The camera takes pictures of the board to be cleaned and transmits the data obtained from the pictures to the control mechanism;

[0028] S3: The control mechanism calculates the data to obtain the two points that minimize the consumption of the board when cleaning both sides of the board to be cleaned separately;

[0029] S4: The two correction mechanisms move separately, moving one side of the board to be cleaned to the point where the straight line formed by the two points obtained in step S3 is parallel to the cutting mechanism.

[0030] S5: The presser foot mechanism near one end of the first frame moves down to press one side of the plate to be cleaned onto the second frame;

[0031] S6: The edge trimming mechanism uses the straight line formed by the two points in step S4 as the path to trim one side of the board to be trimmed.

[0032] S7: The presser foot mechanism in step S5 moves upward, and at the same time the correction mechanism moves the other side of the plate to be cleaned to the straight line formed by the two points obtained in step S3, which is parallel to the upper and lower edge cutting mechanism.

[0033] S8: The presser foot mechanism at the end away from the first frame moves down to press the other side of the plate to be cleaned onto the second frame;

[0035] S10: The presser foot mechanism in step S8 moves upward, and at the same time the unloading mechanism moves the cleaned board out of the board cleaning device.

The frame 8 is connected, and the camera mechanism 4 and the trimming mechanism 5 are both located at the top of the second frame 8. The camera mechanism 4 corresponds to the end of the bridge mechanism 3 that is close to the first frame 7. The unloading mechanism 6 is installed at the end of the second frame 8 that is away from the first frame 7. Multiple presser foot mechanisms 9 are installed in two rows on the second frame 8 and are located above the bridge mechanism 3. The control mechanism is connected to the feeding mechanism 1, the correction mechanism 2, the bridge mechanism 3, the camera mechanism 4, the trimming mechanism 5, the unloading mechanism 6, and the presser foot mechanisms 9.

[0054] It should be noted that only one of the six unloading mechanisms shown in the figure is depicted; in the preferred embodiment, there should be two.

[0055] like Figure 11 As shown, the presser foot mechanism 9 includes: a fixing block 91, a presser foot telescopic cylinder 92, and a presser foot 93. The fixing block 91 is mounted on the second frame 8. The output shaft of the presser foot telescopic cylinder 92 is connected to the presser foot 93, and one end away from the presser foot 93 is connected to the fixing block 91.

[0056] The beneficial effects of this invention are: the correction mechanism, together with the camera mechanism, the presser foot mechanism and the control mechanism, helps to fix and clean the plates with irregular edges in a way that minimizes the amount of plate cutting, thereby reducing the loss of individual plates and improving economic efficiency; at the same time, the control mechanism also helps to improve the automation level of the entire device and reduce manual intervention in the operation process.

[0057] Preferred, such as Figure 3 As shown, the feeding mechanism 1 includes: two chain conveyors 11, multiple limit blocks 12, multiple fixing frames 13, and a synchronous shaft 14. The multiple limit blocks 12 are respectively disposed on the two chain conveyors 11, the multiple fixing frames 13 are respectively installed on the two chain conveyors 11 and connected to the first frame 7, and the two ends of the synchronous shaft 14 are coaxially connected to the sprockets of the two chain conveyors 11 near the second frame 8. The control mechanism is connected to the chain conveyors 11.

[0058] It should be noted that, in the technical solution of the present invention, since the chain conveyor 11 is existing technology and includes components such as a power motor, tensioning assembly, chain and sprocket, the present invention does not describe the specific structure of the chain conveyor 11.

[0059] In a preferred embodiment of the present invention, a plurality of the limiting blocks 12 are evenly arranged on two chain conveyors 11, and the plurality of the limiting blocks 12 on the two chain conveyors 11 are symmetrical.

[0060] The advantages of adopting the above-mentioned preferred solution are: the chain conveyor is conducive to conveying the board to be cleaned, the limiting block is conducive to pushing the board to be cleaned to move towards the bridge mechanism on the chain conveyor, the fixed frame is conducive to fixing the chain conveyor on the first frame, and the synchronous shaft is conducive to synchronizing the movement frequency of the two chain conveyors, thus preventing the board to be cleaned from shifting during transportation.

[0061] Preferred, such as Figure 6 and Figure 12 As shown, the second frame 8 is provided with a first horizontal plate 81 and a second horizontal plate 82 in a direction perpendicular to the first frame 7. The first horizontal plate 81 and the second horizontal plate 82 are parallel and at the same height, and are each divided into three sections by a first partition space 83 and a second partition space 84.

The two rows of presser foot mechanisms 9 correspond one-to-one with the first horizontal plate 81 and the second horizontal plate 82, and the two unloading mechanisms 6 correspond one-to-one with the first partition space 83 and the second partition space 84.

One end of the first fixed bridge plate 31 and the two second fixed bridge plates 32 are connected to the first frame 7, and the other end is connected one-to-one to the three sections of the first horizontal plate 81 divided by the first partition space 83 and the second partition space 84. The other end of the first fixed bridge plate 31 and the second fixed bridge plate 32 are hinged to the movable bridge plate 33. The multiple bridge plate cylinders 34 are mounted on the first frame 7 through the fixing rod 35. The output shafts of the multiple bridge plate cylinders 34 are respectively hinged to the bottom surface of the multiple movable bridge plates 33. The two correction mechanisms 2 are arranged one-to-one in the space between the first fixed bridge plate 31 and the two second fixed bridge plates 32. The control mechanism is connected to the bridge plate cylinders 34.

[0064] The advantages of adopting the above-mentioned preferred scheme are: the first fixed bridge plate and the two second fixed bridge plates provide space for the operation of the two correction mechanisms; the first fixed bridge plate and the two second fixed bridge plates are connected to the first frame and the second frame at the same time, which helps to improve the stability of the plate during movement; the movable bridge plate can be tilted up under the pushing action of the bridge plate cylinder, forming the same plane with the first fixed bridge plate and the two second fixed bridge plates, so that the plate after one side is cleaned can reach the second horizontal plate along the movable bridge plate, thereby achieving the pressing and cleaning of the other side of the plate.

The lower pressure block 210 and the upper pressure block 211 are disposed one-to-one at the top of the supports 206 and the bottom of the crank arm 208. When the output shaft of the deviation correction cylinder 209 is pushed out, the plate to be cleaned is clamped between the lower pressure block 210 and the upper pressure block 211. The top of the lower pressure block 210 is flush with the top of the first fixed bridge plate 31 and the second fixed bridge plate 32.

[0066] The advantages of adopting the above-mentioned preferred solution are: the correction slider is conducive to moving along the correction slide rail under the power of the correction motor, thereby driving the components installed on the correction slider to move. The separate movement of the two correction sliders is conducive to displacing the two sides of the plate to be cleaned by different distances, thereby adjusting the posture of the plate to be cleaned so that the side of the plate to be cleaned is parallel to the cutting mechanism; the correction cylinder is conducive to pushing the crank arm to rotate, thereby causing the lower pressure block and the upper pressure block to clamp the plate to be cleaned, improving the stability of the plate posture adjustment process.

The unloading slide plate 605 is provided with a torsion spring 608 on its bottom surface near the second horizontal plate 82. The hook plate 609 is hinged to the torsion spring 608. When the hook plate 609 rotates to be perpendicular to the end of the unloading slide plate 605 near the second horizontal plate 82, the hook plate 609 protrudes upward from the top surface of the unloading slide plate 605, and the protrusion height is greater than the distance from the top surface of the unloading slide plate 605 to the bottom surface of the fixed stop block 604. The hook plate 609 is disposed between the first horizontal plate 81 and the second horizontal plate 82. The control mechanism is connected to the unloading cylinder 607.

[0074] It should be noted that the operation of the unloading mechanism 6 is divided into two situations. When the unloading cylinder 607 is pushed out, under the action of the torsion spring 608, the hook plate 609 is perpendicular to the end of the unloading slide plate 605 near the second horizontal plate 82, and the hook plate 609 protrudes upward from the top surface of the unloading slide plate 605. When the unloading cylinder 607 is retracted, the part of the hook plate 609 protruding upward from the top surface of the unloading slide plate 605 collides with the fixed stop block 604. Under the action of the retraction pull of the fixed stop block 604 and the unloading cylinder 607, the hook plate 609 folds around the torsion spring 608, that is, changes from a state perpendicular to the unloading slide plate 605 to a state of less than 90 degrees. As for the angle between the hook plate 609 and the unloading slide plate 605 in this state, in the preferred embodiment it is 0 degrees, that is, the hook plate 609 rotates to be parallel to the bottom surface of the unloading slide plate 605.

[0075] The advantages of adopting the above-mentioned preferred solution are: it is beneficial to change the angle between the hook plate and the unloading slide plate by pushing out and retracting the unloading cylinder, thereby realizing the hooking of the plate that has been cleaned and hooking the cleaned plate out of the cleaning device.

[0076] Preferred, such as Figure 6 and Figure 12As shown, the camera mechanism 4 includes a camera bracket 41 and a plurality of industrial cameras 42. The camera bracket 41 is mounted on the top of the second frame 8, and the lenses of the plurality of industrial cameras 42 are mounted downward and evenly on the camera bracket 41. The control mechanism is connected to the industrial cameras 42.

[0077] It should be noted that in the technical solution of the present invention, the control mechanism processes the data of the photos taken by the industrial camera 42 and calculates the corresponding results, which is the prior art. The data processing method involved is not within the protection scope of the present invention.

[0078] The advantages of adopting the above preferred solution are: industrial cameras can take pictures of the board to be cleaned and transmit them to the control mechanism for data processing, thereby obtaining the two points with the least loss on the two sides of the board to be cleaned.

[0079] like Figure 13 As shown, a method for cleaning the edges of a board includes the following steps:

[0080] S1: The feeding mechanism 1 conveys the board to be cleaned to the area below the camera mechanism 4;

[0081] S2: Camera mechanism 4 takes pictures of the board to be cleaned and transmits the data obtained from the pictures to the control mechanism;

[0082] S3: The control mechanism calculates the data to obtain the two points that minimize the consumption of the board when cleaning both sides of the board to be cleaned separately;

[0083] S4: The two correction mechanisms 2 move separately, moving one side of the board to be cleaned to the straight line formed by the two points obtained in step S3, which is parallel to the top and bottom of the cutting mechanism 5.

[0084] S5: The presser foot mechanism 9, which is close to one end of the first frame 7, moves down to press one side of the plate to be cleaned onto the second frame 8;

[0085] S6: The edge trimming mechanism 5 uses the straight line formed by the two points in step S4 as the path to trim one side of the board to be trimmed.

[0086] S7: The presser foot mechanism 9 in step S5 moves upward, and at the same time the correction mechanism 2 moves the other side of the plate to be cleaned to the straight line formed by the two points obtained in step S3, which is parallel to the upper and lower sides of the cutting mechanism 5.

[0087] S8: The presser foot mechanism 9, located away from the first frame 7, moves down to press the other side of the plate to be cleaned onto the second frame 8;

[0088] S9: The edge trimming mechanism 5 uses the straight line formed by the two points in step S7 as the path to trim the other side of the plate to be trimmed.

[0089] S10: The presser foot mechanism 9 in step S8 moves upward, and at the same time the unloading mechanism 6 moves the cleaned board out of the board cleaning device.

[0090] It should be noted that in step S1, a sensor connected to the control mechanism is provided on the first frame 7 at the location corresponding to the first fixed bridge plate 31 and the second fixed bridge plate 32, for detecting whether the plate has been displaced into position by the feeding mechanism 1.

[0091] In step S3, since it is necessary to clean both sides of the board to be cleaned, the control mechanism calculates two points for each side, for a total of four points, forming two straight lines on both sides of the board to be cleaned.

[0092] In step S4, the side of the board to be cleaned that is close to the unloading mechanism 6 is cleaned first. The side of the board to be cleaned needs to be adjusted so that the straight line formed by the two points on the side to be cleaned obtained in step S3 is located directly below the saw blade cutting machine 534 close to the first frame 7.

[0093] In step S5, the presser foot mechanism 9 near one end of the first frame 7 moves down to press the side of the plate to be cleaned near the unloading mechanism 6 onto the first horizontal plate 81.

[0094] In step S6, when the edge trimming mechanism 5 trims the edge of the plate to be trimmed on the side near the unloading mechanism 6, the belt conveyor 522 near one end of the first frame 7 works, so that the saw blade cutter 534 near one end of the first frame 7 trims the edge of the plate to be trimmed on the side near the unloading mechanism 6 along the straight line formed by the two points on the side to be trimmed obtained in step S3.

[0095] In step S7, before the plate moves, the bridge cylinder 34 needs to be pushed out so that the movable bridge plate 33 is flush with the first fixed bridge plate 31 and the second fixed bridge plate 32, so that the plate moves along the first fixed bridge plate 31, the second fixed bridge plate 32 and the movable bridge plate 33 to the foot mechanism 9 at the end away from the first frame 7. To clean the side of the plate to be cleaned away from the unloading mechanism 6, the other side of the plate to be cleaned needs to be adjusted so that the straight line formed by the two points on the other side of the plate to be cleaned obtained in step S3 is located directly below the saw blade cutting machine 534 away from the first frame 7.

[0096] In step S8, the presser foot mechanism 9 at the end away from the first frame 7 moves down to press the side of the plate to be cleaned away from the unloading mechanism 6 onto the second horizontal plate 82;

[0097] In step S9, when the edge trimming mechanism 5 trims the side of the plate to be trimmed away from the unloading mechanism 6, the belt conveyor 522 at the end away from the first frame 7 works, so that the saw blade cutter 534 at the end away from the first frame 7 trims the side of the plate to be trimmed away from the unloading mechanism 6 along the straight line formed by the two points on the side to be trimmed obtained in step S3.

[0098] The beneficial effects of this invention are: it facilitates the edge cleaning operation on both sides of the board with the least amount of loss, thereby improving the utilization rate of the board; at the same time, the control mechanism also helps to improve the automation level of the entire device.

[0099] The working process of the present invention will be further illustrated by the following embodiment:

[0100] like Figures 1 to 12 As shown, multiple pieces of material to be cleaned are evenly placed between two adjacent limit blocks 12. Driven by the chain conveyor 11, the material to be cleaned is pushed by the limit blocks 12 towards the bridge mechanism 3.

[0101] When the plate to be cleaned reaches the bridge mechanism 3, the sensor detects the arrival signal, the chain conveyor 11 stops moving, and the industrial camera 42 takes a picture of the plate to be cleaned and transmits the data to the control mechanism. The control mechanism calculates the two points with the least cleaning loss on each side of the plate to be cleaned.

[0102] The correction motors 204 and correction cylinders 209 in the two correction mechanisms 2 work respectively. The two correction cylinders 209 are pushed out, clamping both sides of the plate between the lower pressure block 210 and the upper pressure block 211. At the same time, the correction slider 203 is displaced by different distances on the correction slide rail 202, thereby causing the straight line formed by the two marked points on the first edge of the plate to be cleaned to be displaced to below the saw blade cutting machine 534 near the first frame 7.

[0103] A row of presser foot telescopic cylinders 92 near the first frame 7 are extended, causing the presser foot 93 to press the first edge of the board to be cleaned onto the first horizontal plate 81. Then, the displacement power motor 521 near the first frame 7 works, driving the sawing assembly 53 mounted on the mounting plate 524 to move along the cutting slide rail 523. At the same time, the sawing power motor 531 drives the working saw blade cutting machine 534 to rotate at high speed to clean the first edge of the board to be cleaned.

[0104] The row of presser foot telescopic cylinders 92 near the first frame 7 retracts, releasing the restriction on the plate to be cleaned. At the same time, the bridge plate cylinder 34 extends, rotating the movable bridge plate 33 to a state flush with the first fixed bridge plate 31 and the second fixed bridge plate 32, so that the movable bridge plate 33 connects the first horizontal plate 81 and the second horizontal plate 82.

[0105] The correction motor 204 in the correction mechanism 2 continues to work, displacing the straight line formed by the two marked points on the other side of the plate to be cleaned to below the saw blade cutting machine 534, which is far away from the first frame 7.

[0106] The row of presser foot telescopic cylinders 92, which are away from the first frame 7, are extended, so that the presser foot 93 presses the other edge of the board to be cleaned onto the second horizontal plate 82. Then, the displacement power motor 521, which is away from the first frame 7, works, driving the sawing assembly 53, which is mounted on the mounting plate 524, to move along the cutting slide rail 523. At the same time, the sawing power motor 531 drives the working saw blade cutting machine 534 to rotate at high speed to clean the other edge of the board to be cleaned.

[0107] The row of presser foot telescopic cylinders 92, which are away from the first frame 7, retract, thereby releasing the plate that has been cleaned. At the same time, the bridge plate cylinder 34 retracts, causing the movable bridge plate 33 to rotate back to its initial state, thereby releasing the connection between the first horizontal plate 81 and the second horizontal plate 82.

[0108] The unloading cylinder 607 is pushed out, which releases the contact between the fixed block 604 and the part of the hook plate 609 protruding from the unloading slide plate 605, thereby making the hook plate 609 and the unloading slide plate 605 perpendicular to each other and located between the side of the plate being cleaned for the second time and the first horizontal plate 81.

[0109] The unloading cylinder 607 retracts, and the vertical hook plate 609 hooks the cleaned board away from the first frame 7. The board cleaning is completed. At this time, the board will not be a rectangular board after equidistant cutting in the traditional sense, but will be trapezoidal. That is, the two sides of the board that have been cleaned are cleaned with the tangent line that minimizes board loss.
