Description

Technical Field

[0001] The present invention relates to the technical field of wood board detection equipment, and particularly relates to a hole detection device for visual veneered wood. Background Art

[0002] Veneered wood is a new type of all-wood decorative material with more excellent performance, which is made from ordinary wood as raw materials, using the principle of bionics, and through various modification and physical-chemical treatments of ordinary wood and fast-growing wood. Compared with natural wood, it is almost not bent, cracked, or distorted. Its density can be artificially controlled, and the product has good stability. During the processing process, there is no waste and value loss during the processing of natural wood. Veneered wood is not solid wood, but an artificially synthesized composite product.

[0003] In Chinese Patent (Application No.: CN202220798580.3), a double-station X-ray wood board defect detection device is disclosed. Its technical solution is as follows: It includes a base. Inside the base, multiple fixing plates are fixedly arranged. On one side of each of the multiple fixing plates, a travel groove is opened. At the bottom of the base, multiple limiting grooves are fixedly arranged. A fixing mechanism is arranged inside the base; the fixing mechanism includes a fixing component, and the fixing component includes a bidirectional threaded rod. The beneficial effect of a double-station X-ray wood board defect detection device is that: by rotating the bidirectional threaded rod in the fixing mechanism forward, the clamping blocks on both sides clamp the wood board, achieving the purpose of automatically positioning the center position of the wood board. After the detection is completed, by rotating the bidirectional threaded rod in reverse, the clamping blocks loosen the wood board. At the same time, the connecting columns on both sides move towards both ends of the travel groove. Affected by the shapes at both ends of the travel groove, the connecting columns drive the movable sleeves to move downward, causing the clamping blocks to retract into the through grooves again, so that there are no obstacles on the surface of the detection table, facilitating the removal of the wood board after the detection is completed.

[0004] The following technical problems exist in the actual use process of this patent and the prior art: 1. Generally, the existing veneered wood boards can only detect holes on the top surface, but there are generally also holes and scratches on the bottom surface of the existing veneered wood boards. Therefore, the operator needs to turn the veneered wood over and then move it to the detection device again for detection. Therefore, it needs to be improved.

[0005] 2. At the same time, generally, the existing veneered wood boards cannot detect holes on the side surface, and during the production process of the existing veneered wood, there are also likely to be relatively large holes and other damages on the side surface. Therefore, it needs to be improved. Summary of the Invention

[0006] The purpose of the present invention is: to solve the above problems, the present invention provides a hole detection device for visual veneered wood.

[0007] The present invention specifically adopts the following technical solutions to achieve the above purpose: A hole detection device for visualizing technology wood, comprising a conveying frame. Inside the conveying frame, conveying wheels are equidistantly installed. A wooden board is placed on the conveying wheels. A detection frame is fixed on the top of the conveying frame. A fixing plate is fixed at the lower end of the conveying frame. A lifting mechanism is installed on the fixing plate. A moving plate is drivingly connected to the lifting mechanism. A rotating mechanism is drivingly connected to the moving plate. At both ends of the top of the moving plate, a blocking block and a side plate located between the conveying wheels are respectively fixed. The upper end of the side plate is hinged with a hinge block. A double-shaft motor is fixed on the top of the moving plate. A first driving wheel is drivingly connected to the double-shaft motor. A first driven wheel is fixedly connected to the side of the upper end of the hinge block. The first driving wheel is drivingly connected to the first driven wheel through a first transmission belt.

[0008] Further, the lifting mechanism includes an electric telescopic rod and a socket rod. The electric telescopic rod is fixedly sleeved inside the fixing plate. The socket rod is limitedly sleeved inside the moving plate. The lower end of the socket rod is drivingly connected to the electric telescopic rod.

[0009] Further, the rotating mechanism includes a driving motor, a first gear and a second gear. The driving motor is fixed on the fixing plate. The driving motor is drivingly connected to the first gear. The second gear is fixed at the bottom of the moving plate.

[0010] Further, a braking motor is fixed at the lower end of the conveying frame. A rotating rod is drivingly connected to the braking motor. The other end of the rotating rod penetrates through the conveying frame and is fixedly sleeved with a second driving wheel. A third transmission belt is drivingly connected to the second driving wheel. The other end of the third transmission belt is drivingly connected to a second driven wheel. The second driven wheel is drivingly connected to the conveying wheel.

[0011] Further, one end of the conveying wheel is fixedly connected with a connecting wheel. The number of the connecting wheels is thirty. A second transmission belt is drivingly connected to each of the thirty connecting wheels.

[0012] Further, the number of the blocking blocks is two. The lengths of the two blocking blocks are longer than the length of the side plate.

[0013] Further, side ring blocks are respectively fixedly sleeved at both ends of the outer surface of the conveying wheel. The side surface of the side ring block is in contact with the side surface of the wooden board.

[0014] Further, a controller is fixedly installed on the side surface of the detection frame. The controller is electrically connected to the detection frame and the braking motor respectively.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention moves the moving plate upward, so that the moving plate drives the blocking block and the side plate through the conveying wheels, and then the blocking block blocks one side of the wooden board. Then, by starting the double-shaft motor, the first driving wheel drives the first driven wheel to rotate through the first transmission belt, and then the first driven wheel drives the hinge block to rotate and push the wooden board to rotate and tilt against the blocking block until the detection frame can detect the side of the wooden board and then stop. By repeating such operations, hole detection can be performed on all sides of the wooden board.

[0016] 2. The present invention moves the moving plate upward, so that the moving plate drives the blocking block and the side plate through the conveying wheels, and the blocking block blocks one side of the wooden board. At the same time, by starting the double-shaft motor, the first driving wheel drives the first driven wheel to rotate through the first transmission belt, and then the first driven wheel drives the hinge block to rotate and push the wooden board to flip against the blocking block until the wooden board flips to the upper end of the blocking block and then stops. At this time, the hinge block will squeeze the wooden board against the upper end of the blocking block to prevent the wooden board from directly flipping onto the conveying wheels and causing damage. Then, the entire moving plate is moved downward so that the detection frame can perform hole detection on the bottom surface of the wooden board.

[0017] 3. The present invention starts the brake motor, so that the rotating rod drives the second driving wheel to rotate, and then the second driving wheel drives the second driven wheel to rotate through the third transmission belt, so that the second driven wheel drives the conveying wheel to rotate, and then the conveying wheel drives all the conveying wheels to rotate synchronously through the connecting wheel and the second transmission belt, so that the synchronously rotating conveying wheels can sequentially convey the wooden boards for hole detection, thereby improving the detection efficiency of the device for the wooden boards.

Detailed implementation manners

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Embodiment 1, as Figures 1-7 shown, a hole detection device for visualizable engineered wood includes a conveying frame 1. Conveying wheels 3 are equidistantly installed inside the conveying frame 1. A wooden board 26 is placed on the conveying wheels 3. A detection frame 2 is fixed on the top of the conveying frame 1. A fixing plate 12 is fixed at the lower end of the conveying frame 1. A lifting mechanism is installed on the fixing plate 12. A moving plate 4 is drivingly connected to the lifting mechanism. A rotating mechanism is drivingly connected to the moving plate 4. Blocking blocks 5 and side plates 6 located between the conveying wheels 3 are respectively fixed at both ends of the top of the moving plate 4. A hinge block 7 is hinged to the upper end of the side plate 6. A dual-axis motor 8 is fixed on the top of the moving plate 4. A first driving wheel 9 is drivingly connected to the dual-axis motor 8. A first driven wheel 11 is fixedly connected to the side surface of the upper end of the hinge block 7. The first driving wheel 9 is drivingly connected to the first driven wheel 11 through a first transmission belt 10.

[0022] When it is necessary to detect the side surface of the wooden board 26, at this time, the moving plate 4 moves upward through the lifting mechanism, so that the moving plate 4 drives the blocking block 5 and the side plate 6 to pass through the conveying wheels 3, and then the blocking block 5 blocks one side of the wooden board 26, and the side plate 6 will push the other end of the wooden board 26, and the wooden board 26 will gradually tilt. Then, by starting the dual-axis motor 8, the first driving wheel 9 drives the first driven wheel 11 to rotate through the first transmission belt 10, and then the first driven wheel 11 drives the hinge block 7 to rotate and push the wooden board 26 to rotate and tilt against the blocking block 5 until the detection frame 2 can detect the side surface of the wooden board 26 and then stop. Then, the lifting mechanism drives the whole moving plate 4 to move downward, and the blocking block 5 and the side plate 6 and the hinge block 7 are located below the conveying wheels 3. Subsequently, the moving plate 4 rotates 90 degrees through the rotating mechanism and detects the other side of the wooden board 26. By repeating such operations, all side surfaces of the wooden board 26 can be detected for holes; When it is necessary to detect the back surface of the wooden board 26, at this time, the moving plate 4 moves upward through the lifting mechanism, so that the moving plate 4 drives the blocking block 5 and the side plate 6 to pass through the conveying wheel 3, and then the blocking block 5 blocks one side of the wooden board 26. At the same time, by starting the double-shaft motor 8, the first driving wheel 9 drives the first driven wheel 11 to rotate through the first transmission belt 10, and then the first driven wheel 11 drives the hinge block 7 to rotate and push the wooden board 26 to flip against the blocking block 5 until the wooden board 26 flips to the upper end of the blocking block 5 and stops. At this time, the upper end of the blocking block 5 will support the wooden board 26, and the hinge block 7 will pull the other end of the wooden board 26 to prevent the wooden board 26 from directly flipping onto the conveying wheel 3 and causing damage. Then the moving plate 4 moves downward through the lifting mechanism until the wooden board 26 moves onto the conveying wheel 3 and stops. At this time, the detection frame 2 can detect the holes on the bottom surface of the wooden board 26.

[0023] Embodiment 2, as Figures 1-4 shown, the lifting mechanism includes an electric telescopic rod 13 and a socket rod 14. The electric telescopic rod 13 is fixedly sleeved inside the fixed plate 12, the socket rod 14 is limitedly sleeved inside the moving plate 4, and the lower end of the socket rod 14 is in transmission connection with the electric telescopic rod 13.

[0024] By starting the electric telescopic rod 13, the socket rod 14 drives the entire moving plate 4 to move upward, so that the moving plate 4 drives the blocking block 5 and the side plate 6 to pass through the conveying wheel 3, and the blocking block 5 blocks the wooden board 26, so that the side plate 6 pushes one end of the wooden board 26 to rotate and tilt against the blocking block 5, thus achieving the purpose of moving the side plate 6 to push the wooden board 26.

[0025] Embodiment 3, as Figure 4 shown, the rotating mechanism includes a driving motor 25, a first gear 15 and a second gear 16. The driving motor 25 is fixed on the fixed plate 12, the driving motor 25 is in transmission connection with the first gear 15, and the second gear 16 is fixed at the bottom of the moving plate 4.

[0026] When the moving plate 4 moves to the position where the second gear 16 is meshed with the first gear 15, at this time, by starting the driving motor 25, the driving motor 25 drives the first gear 15 to drive the second gear 16 to rotate, and then the second gear 16 drives the entire moving plate 4 to rotate until the moving plate 4 rotates 90 degrees and stops, thus achieving the purpose of rotating the moving plate 4, and further enabling the device to detect the holes on each side of the wooden board 26.

[0027] Embodiment 4, as Figure 5 and Figure 6As shown in the figure, a braking motor 19 is fixed to the lower end of the conveying frame 1. A rotating rod 20 is drivingly connected to the braking motor 19. The other end of the rotating rod 20 penetrates through the conveying frame 1 and is fixedly sleeved with a second driving wheel 21. A third transmission belt 22 is drivingly connected to the second driving wheel 21. The other end of the third transmission belt 22 is drivingly connected to a second driven wheel 23. The second driven wheel 23 is drivingly connected to the conveying wheel 3.

[0028] By starting the braking motor 19, the rotating rod 20 drives the second driving wheel 21 to rotate. Then, the second driving wheel 21 drives the second driven wheel 23 to rotate through the third transmission belt 22. Thus, the second driven wheel 23 drives the wooden board 26 to move through the conveying wheel 3, so that the wooden board 26 can be better detected by the detection frame 2.

[0029] Example Five, as Figure 1 As shown in the figure, one end of the conveying wheel 3 is fixedly connected with a connecting wheel 17. The number of the connecting wheels 17 is thirty. A second transmission belt 18 is drivingly connected to each of the thirty connecting wheels 17.

[0030] Through the design of the connecting wheel 17, the second transmission belt 18 and the conveying wheel 3, when the braking motor 19 drives one conveying wheel 3 to rotate, the conveying wheel 3 drives all the conveying wheels 3 to rotate synchronously through the connecting wheel 17 and the second transmission belt 18. Then, the synchronously rotating conveying wheels 3 can convey the wooden board 26 in sequence for hole detection.

[0031] Example Six, as Figure 3 As shown in the figure, the number of the blocking blocks 5 is two. The lengths of the two blocking blocks 5 are longer than the length of the side plate 6.

[0032] Through the design of the blocking block 5 and the side plate 6, when the electric telescopic rod 13 drives the moving plate 4 to move upward as a whole, the upper end of the blocking block 5 can be moved above the conveying wheel 3 by the moving plate 4, and the upper end of the side plate 6 can be moved below the conveying wheel 3. Thus, the upper end of the blocking block 5 can limit and block the rotation of the conveying wheel 3 to drive the wooden board 26, so that the wooden board 26 is exactly located below the detection frame 2, and the wooden board 26 can be better detected by the detection frame 2.

[0033] Example Seven, as Figure 2 As shown in the figure, side ring blocks 24 are respectively and fixedly sleeved at both ends of the outer surface of the conveying wheel 3. The side surfaces of the side ring blocks 24 are in contact with the side surfaces of the wooden board 26.

[0034] Through the design of the side ring block 24 and the wooden board 26, the side ring block 24 can limit and block the wooden board 26 to a specific position of the conveying wheel 3. When the driving motor 25 drives the moving plate 4 to rotate 90 degrees, the moving plate 4 can drive the blocking block 5 to move to one side of the wooden board 26. When the moving plate 4 moves upward, the upward moving blocking block 5 is located on one side of the wooden board 26. Furthermore, the side plate 6 can press the wooden board 26 against the blocking block 5 for flipping and tilting, so that the blocking block 5 will not push the wooden board 26 when it moves upward.

[0035] Embodiment 8, as Figures 1-6 shown, a controller 27 is fixedly installed on the side of the detection frame 2, and the controller 27 is electrically connected to the detection frame 2 and the brake motor 19 respectively.

[0036] Through the design of the controller 27, the detection frame 2 and the brake motor 19, when the brake motor 19 drives the conveying wheel 3 to drive the wooden board 26 to move and contact the blocking block 5, the detection frame 2 will detect the contact between the wooden board 26 and the blocking block 5 and transmit the detection signal to the controller 27. Thus, the controller 27 controls the conveying wheel 3 to stop rotating through the brake motor 19, and further enables the conveying wheel 3 on the wooden board 26 to better stop below the detection frame 2 for hole detection.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
