Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to a particleboard defect detection and sorting device. Background Art

[0002] Particleboard is also called particle board. It is a board made of wood chips as the main raw material and pressed under high temperature and high pressure. It uses the residues in the wood processing process, such as bark, branches and scraps. After crushing, screening and drying, it is mixed with adhesives and then pressed into shape. In the process of particleboard processing, defects will affect the strength, stability and appearance of the particleboard. Defective particleboard cannot meet the product quality requirements. For example, the use of defective particleboard in furniture manufacturing is prone to cause deformation and cracking of furniture, thereby affecting the service life of the product and user experience. Detecting and eliminating defective particleboard products is the key to ensuring product quality and reputation. Particleboard defect detection and sorting equipment is a device used to detect and sort various defects, flaws and stains in particleboard.

[0003] Existing particleboard defect detection and sorting equipment sorts particleboard into different grades by detecting defects and flaws in the particleboard, and uses the same driving device to quickly distinguish and classify the graded particleboard. However, during the processing and manufacturing of the particleboard, insufficient pressing pressure may lead to insufficient bonding between the particles and the formation of voids. The surface of this type of particleboard is relatively fragile, and is easily damaged and broken due to the friction of the conveying equipment during the sorting and conveying process.

The output end of the reducer 526 is fixedly connected to the outer surface of the third bevel gear 527. The bottoms of the first roller conveyor 501 and the second roller conveyor 502 are both screwed to the support plate 1.

[0023] In this embodiment, after the particleboard is processed and produced, when it is necessary to inspect the particleboard for defects, the particleboard is first placed on the top of the first conveyor belt 201, and the first conveyor belt 201 is started to drive the conveying device on the first conveyor belt 201 to operate, thereby conveying the particleboard to the bottom of the inspection frame 202, wherein the working principle of the first conveyor belt 201 is that the driving device drives the rotation of the roller to drive the connected conveyor belt to move, and the conveyor belt moves forward under the drive of the roller, and carries the particleboard on the surface of the belt body, thereby realizing the transportation of the particleboard. When the particleboard moves to the bottom of the inspection frame 202, the ultrasonic detector 204 is started by the controller 203 at the same time, wherein the ultrasonic detector 204 will encounter defects when propagating in the particleboard. When encountering different media, such as cavities and defects, in a uniform particleboard, the ultrasonic wave will propagate at a relatively stable speed. However, when encountering areas with cavities and defects, the propagation speed of the ultrasonic wave will change and reflection will occur. By analyzing these signal changes, the ultrasonic detector 204 can effectively detect various defects inside the particleboard, providing a reliable basis for product quality control. The ultrasonic detector 204 detects whether there are cavities and cracks in the particleboard, and transmits the detected signal to the controller 203. The controller 203 analyzes and determines the quality grade of the particleboard, and transmits it to the conveying equipment corresponding to the quality of the particleboard through the second conveyor belt 304. In the process of conveying particleboards of different qualities, In order to realize the conveying at different speeds according to the actual situation of the particle board, the servo motor 504 is started to drive the connecting rod 505 to rotate, and then drive the driving gear 506 to rotate, thereby driving the driven gear 507 connected thereto to rotate, and then drive the multiple rollers on the first roller conveyor 501 to rotate, thereby driving another driven gear 507 to rotate, and through the rotation of multiple rollers, the conveying of high-quality particle board is realized. Among them, the working principles of the first roller conveyor 501, the second roller conveyor 502 and the third roller conveyor 525 are the same, and the transmission of the conveyor is realized by the gear device between the rollers. The rotation of the surface roller of the first roller conveyor 501 drives the driven gear 50 set near the carrier frame 522 7 rotates, thereby driving the second bevel gear 524 to rotate, thereby driving the third bevel gear 527 to rotate, and the speed of the third bevel gear 527 is reduced by the speed reducer 526 to drive the output shaft on the third roller conveyor 525 connected thereto to rotate, thereby driving the multiple rollers on the third roller conveyor 525 to rotate, thereby realizing the transmission of the particle board with good quality, wherein the speed reducer 526 uses the meshing of the worm wheel and the worm to reduce speed, and the rotation of the worm drives the rotation of the worm wheel. Due to the threaded structure of the worm, the speed of the worm is much higher than the speed of the worm wheel, so a larger reduction ratio can be achieved, and the speed of each roller on the third roller conveyor 525 is reduced by the speed reducer 526. The lower speed improves the stability of the particle board on the conveyor belt,The possibility of rolling, sliding and tilting caused by rapid movement is reduced, which helps to protect the shape and integrity of the particle board. At the same time, the rotation of the driving gear 506 also drives the first bevel gear 510 to rotate, wherein, for example, Fig. 9 As shown, the teeth of the first bevel gear 510 are relatively sparse, and the purpose is to reduce the rotation speed of the first bevel gear 510 per unit time, thereby reducing the rotation of the second roller conveyor 502 in the later stage. The rotation of the first bevel gear 510 drives the connecting shaft 509 to rotate, wherein the stability of the connecting shaft 509 is ensured by movably embedding the connecting shaft 509 inside the connecting rod 508. The rotation of the connecting shaft 509 drives the gear ring 512 to rotate, thereby driving the internal gear 513 and multiple gears such as Fig.13 The stopper 517 shown in the figure rotates synchronously, wherein the stopper 517 is arranged between each two adjacent protrusions in the gear ring 512, playing the role of the inner teeth of the inner gear 513, thereby driving the driving rod 511 to rotate, and then driving the output shaft of the second roller conveyor 502 to rotate, thereby realizing the rotation of multiple rollers on the surface of the second roller conveyor 502, and realizing the transportation of particleboards with poor quality. When the ultrasonic detector 204 detects that there are particleboards with serious surface damage, in order to prevent the particleboards from being damaged during the transportation process, When the severely damaged particleboard moves to the surface of the second roller conveyor 502, the two-way air pump 519 is started to drive the suction pipe 521 to extract gas into the hollow ring 518, and then to extract gas into the multiple sealing cylinders 514, so that the multiple pistons 515 are moved to the outside of the hollow ring 518 under the action of negative pressure, and then drive the multiple moving rods 516 to move into the multiple sealing cylinders 514, so as to drive the multiple stoppers 517 to move backward, so as to move out the Fig.13 Between every two adjacent teeth of the tooth ring 512 shown, when the tooth ring 512 rotates, the rotation rate of the internal gear 513 is reduced by half, so that the rotation speed of the second roller conveyor 502 is reduced again, and the purpose of slowly conveying the particle board that is about to break is achieved. Through the action of the diversion component 5, different speeds of conveying particle boards of different qualities are achieved, which effectively improves the protection level of the particle board by the particle board defect detection and sorting equipment, and solves the problem in the prior art that most particle board defect detection and sorting equipment do not select different conveying methods according to the actual situation of the particle board, which easily leads to secondary damage to the particle board.

[0024] like Figure 1 and Figure 4-Figure 5As shown, a positioning assembly 3 is arranged near the center of the top of the support plate 1, and the positioning assembly 3 includes a base plate 301, the bottom of the base plate 301 is fixedly connected to the top of the support plate 1, a rotating sleeve 302 is movably embedded inside the base plate 301, a turntable 303 is fixed on the top of the rotating sleeve 302, a second conveyor belt 304 is arranged inside the turntable 303, a driving motor 305 is arranged near the center of the top of the base plate 301, the output shaft of the driving motor 305 is fixedly connected to the driving shaft 306, and the top end of the driving shaft 306 is fixedly connected to the bottom of the turntable 303.

[0025] In this embodiment, when it is detected that the quality of the particle board is excellent, it means that the particle board has the least defects and voids and the best strength, and the second conveyor belt 304 is started. The working principle of the second conveyor belt 304 is the same as that of the first conveyor belt 201, and no further introduction is given here. The rotation of the second conveyor belt 304 drives the particle board to move along the first conveyor belt 201 to the surface of the second conveyor belt 304 until the outer surface of the particle board contacts the inner wall of the turntable 303, and the drive motor 305 is started to drive the drive shaft 306 to rotate and drive the turntable 303 to rotate, wherein the rotating sleeve 302 supports and limits the turntable 303, and the rotation of the turntable 303 drives the second conveyor belt 304 to rotate until the output end of the second conveyor belt 304 is in the same straight line as the first roller conveyor 501, and the second conveyor belt 304 can be started in reverse again. The conveyor belt 304 drives the conveyor belt on the second conveyor belt 304 to rotate in the opposite direction, thereby conveying the particle board to the surface of the first roller conveyor 501. When it is detected that the quality of the particle board is good, it means that the particle board has certain defects and voids and the quality is poor. The output end of the second conveyor belt 304 can be rotated to the position corresponding to the third roller conveyor 525 by driving the motor 305, so that the particle board with good quality is conveyed to the surface of the third roller conveyor 525. When it is detected that there are many defects and voids in the particle board, it means that the quality of the particle board is poor and the strength is low. The output end of the second conveyor belt 304 is rotated to the position corresponding to the second roller conveyor 502, and the particle board with poor quality can be conveyed to the top of the second roller conveyor 502. Through the action of the positioning component 3, the graded transportation of the particle board is realized.

[0026] like Figure 1 and Figure 6 As shown, a pressing assembly 4 for fixing the particle board is provided on the top of the turntable 303, and the pressing assembly 4 includes a connecting frame 401, the bottom of the connecting frame 401 is fixedly connected to the top of the turntable 303 near one side edge, an electric push rod 402 is provided on the inner top surface of the connecting frame 401, and a pressing block 403 is fixedly connected to the bottom end of the electric push rod 402.

[0027] In this embodiment, during the process of the turntable 303 driving the particle board to rotate, in order to prevent the particle board from being affected by inertia and moving out of the surface of the second conveyor belt 304 during the rotation, the electric push rod 402 is started to extend, driving the pressing block 403 to move downward until the bottom of the pressing block 403 is tightly attached to the top of the particle board, thereby completing the positioning of the particle board and preventing the particle board from shifting during the rotation.

[0028] The use method and working principle of the device: After the particle board is processed and produced, when it is necessary to detect defects on the particle board, first place the particle board on the top of the first conveyor belt 201, and start the first conveyor belt 201 to drive the conveying equipment on the first conveyor belt 201 to operate, so as to convey the particle board to the bottom of the detection frame 202. When the particle board moves to the bottom of the detection frame 202, the ultrasonic detector 204 is started by the controller 203 at the same time. The ultrasonic detector 204 detects whether there are cavities and cracks in the particle board, and transmits the detected signal to the controller 203. The controller 203 analyzes and determines the quality grade of the particle board. When the quality of the particle board is detected to be excellent, it indicates that the particle board has defects and The second conveyor belt 304 is started, and the rotation of the second conveyor belt 304 drives the particle board to move along the first conveyor belt 201 to the surface of the second conveyor belt 304 until the outer surface of the particle board contacts the inner wall of the turntable 303, and the drive motor 305 is started to drive the drive shaft 306 to rotate and drive the turntable 303 to rotate. In the process of the turntable 303 driving the particle board to rotate, in order to prevent the particle board from being affected by inertia during the rotation and moving out of the surface of the second conveyor belt 304, the electric push rod 402 is started at this time to extend it, and drive the pressing block 403 to move downward until the bottom of the pressing block 403 is tightly attached to the top of the particle board, that is, the positioning of the particle board is completed, and the rotating sleeve 302 is pressed against the turntable 303 plays a supporting and limiting role. The rotation of the turntable 303 drives the second conveyor belt 304 to rotate until the output end of the second conveyor belt 304 is in the same straight line with the first roller conveyor 501. The second conveyor belt 304 can be started in reverse again to drive the conveyor belt on the second conveyor belt 304 to rotate in the opposite direction, thereby conveying the particleboard to the surface of the first roller conveyor 501. When it is detected that the quality of the particleboard is good, it means that there are certain defects and voids in the particleboard and the quality is poor. The output end of the second conveyor belt 304 can be rotated to the position corresponding to the third roller conveyor 525 by driving the motor 305, thereby conveying the particleboard with good quality to the surface of the third roller conveyor 525. When it is detected that the particleboard is of good quality, it means that there are certain defects and voids in the particleboard and the quality is poor. When there are many defects and voids on the particleboard, it means that the quality of the particleboard is poor and the strength is low. The output end of the second conveyor belt 304 is rotated to the position corresponding to the second roller conveyor 502, so that the particleboard with poor quality can be conveyed to the top of the second roller conveyor 502. In the process of conveying particleboards of different qualities, in order to realize different speeds of conveying according to the actual situation of the particleboard, the servo motor 504 is started to drive the connecting rod 505 to rotate, and then drive the driving gear 506 to rotate, thereby driving the driven gear 507 connected thereto to rotate, and then drive the multiple rollers on the first roller conveyor 501 to rotate, thereby driving another driven gear 507 to rotate. Through the rotation of multiple rollers, both the transportation of high-quality particleboards andThe rotation of the surface roller of the first roller conveyor 501 drives the driven gear 507 arranged near the carrier frame 522 to rotate, and then drives the second bevel gear 524 to rotate, thereby driving the third bevel gear 527 to rotate. The speed of the third bevel gear 527 is reduced by the speed reducer 526 and drives the output shaft on the third roller conveyor 525 connected thereto to rotate, thereby driving the multiple rollers on the third roller conveyor 525 to rotate, thereby realizing the transmission of good quality particleboard. The speed of each roller on the third roller conveyor 525 is reduced by the speed reducer 526. The lower speed improves the stability of the particleboard on the conveyor belt, reduces the possibility of rolling, sliding and tilting caused by rapid movement, and helps to protect the shape and integrity of the particleboard. At the same time, the rotation of the driving gear 506 also drives the first bevel gear 510 to rotate, wherein, for example, Fig. 9 As shown, the teeth of the first bevel gear 510 are relatively sparse, the purpose of which is to reduce the rotation speed of the first bevel gear 510 per unit time, thereby reducing the rotation of the second roller conveyor 502 in the later stage. The rotation of the first bevel gear 510 drives the connecting shaft 509 to rotate, wherein the stability of the connecting shaft 509 is ensured by movably embedding the connecting shaft 509 inside the connecting rod 508. The rotation of the connecting shaft 509 drives the gear ring 512 to rotate, and then drives the internal gear 513 to rotate, thereby driving the driving rod 511 to rotate, and then drives the output shaft of the second roller conveyor 502 to rotate, thereby realizing the rotation of multiple rollers on the surface of the second roller conveyor 502, and realizing the poor quality of the When the ultrasonic detector 204 detects a particle board with serious surface damage, in order to prevent the particle board from breaking during transportation and affecting the later storage, when the particle board with serious damage moves to the surface of the second roller conveyor 502, the two-way air pump 519 is started to drive the suction pipe 521 to draw gas into the interior of the hollow ring 518, and then to draw gas into the interior of the multiple sealing cylinders 514, so that the multiple pistons 515 are moved to the outside of the hollow ring 518 under the action of negative pressure, and then drive the multiple moving rods 516 to move into the interior of the multiple sealing cylinders 514, thereby driving the multiple blocks 517 to move backward, so as to move out. Fig.13 Between every two adjacent teeth of the gear ring 512 shown, when the gear ring 512 rotates, the speed of the internal gear 513 is reduced by half, so that the rotation speed of the second roller conveyor 502 is reduced again, and the purpose of slowly conveying the particle board that is about to break is achieved, wherein the controller 203 is electrically connected to the first conveyor belt 201, the ultrasonic detector 204, the drive motor 305, the electric push rod 402, the servo motor 504 and the two-way air pump 519.
