[0002] Bamboo and wood products refer to products made of ecological boards such as bamboo boards or wooden boards. In order to ensure product quality, the bamboo and wood ecological boards used must be tested for flatness before production. In large-scale production, flatness testing devices are generally used to test and process bamboo and wood ecological boards.

[0003] The existing flatness detection device uses optical imaging to perform detection and processing. This detection method is highly efficient and accurate, but during the detection process, only the upper and lower surfaces of the board can be detected. However, a board is composed of six sides, including the left and right sides and the front and back sides in addition to the upper and lower surfaces. The currently used detection device is difficult to directly perform flatness detection on the left and right sides and the front and back sides of the board. Therefore, the overall flatness of the board cannot be ensured, which will increase the difficulty of subsequent splicing between boards and affect product quality. Therefore, it is necessary to design a bamboo and wood ecological board flatness detection device. Summary of the invention

[0034] Reference Figure 1 A bamboo and wood ecological board flatness detection device includes a mounting plate 1 and a rotating plate 5. Two support frames 2 are fixedly installed at the bottom of the mounting plate 1. Two shielding plates 6 symmetrically arranged up and down are fixedly installed on the mounting plate 1. The shielding plates 6 can be used to block external dust and light sources. The support frame 2 is used to ensure the stability of the device. A fixing frame 3 is fixedly installed on the mounting plate 1, and a motor 4 is fixedly installed on the fixing frame 3. The output end of the motor 4 is fixedly connected to the rotating plate 5. The motor 4 can specifically adopt a motor that can only rotate in one direction commonly seen in daily life and work. When the motor 4 is working, it can drive the rotating plate 5 to rotate relative to the mounting plate 1.

[0035] Reference Figure 1-Figure 10 , a bamboo and wood ecological board flatness detection device also includes: a clamping part, the clamping part is used to clamp the ecological board and adjust the clamping angle of the ecological board, the clamping part includes a plurality of clamping components, the clamping component includes a fixed plate 7 fixedly mounted on the rotating disk 5, and a movable plate 8 is installed on the fixed plate 7 through a lifting mechanism, the lifting mechanism adjusts the distance between the movable plate 8 and the fixed plate 7 according to the angle change of the rotating disk 5 relative to the mounting disk 1, and baffles 33 are fixedly installed on the side walls of the fixed plate 7 and the movable plate 8 close to the midpoint of the rotating disk 5, and the two baffles 33 are staggered left and right. Under the design of the baffles 33, the bamboo and wood ecological board can be limited when the rotating disk 5 rotates and the bamboo and wood ecological board is not fixed, thereby preventing it from moving from the fixed plate 7 or the movable plate 8 To solve the problem of falling off, when the device is used specifically, a conveyor belt is arranged on the left and right sides of the device respectively, wherein the conveyor belt on the right side of the device is a loading conveyor belt, and the conveyor belt on the left side of the device is a unloading conveyor belt. The conveyor belt is a common conveyor belt for transporting objects, so it is not shown in the figure, and its working principle and specific structure are not elaborated here. When it is used specifically, it is only necessary to rotate the rotating disk 5 to make the fixed plate 7 rotate to be nearly horizontal with the right conveyor belt, so that the right conveyor belt pushes the bamboo and wood ecological board to be tested onto the fixed plate 7 to complete the loading process. After that, when the fixed plate 7 is rotated to be nearly horizontal with the left conveyor belt, the tested bamboo and wood ecological board can fall from the left side onto the conveyor belt under the action of gravity to realize the unloading process.

[0036] The lifting mechanism is composed of a vertical plate 9, a slider 10, a lifting screw rod 11, a connecting plate 12, a rotating rod 13, an active bevel gear 14, a driven bevel gear 15 and a fixed gear 16. The vertical plate 9 is fixedly mounted on the side wall of the fixed plate 7, the slider 10 is fixedly mounted on the side wall of the movable plate 8, and the slider 10 is slidably matched with the vertical plate 9, the lifting screw rod 11 is rotatably mounted on the vertical plate 9, and the lifting screw rod 11 is threadedly connected to the slider 10, the connecting plate 12 is fixedly mounted on the side wall of the vertical plate 9, the rotating rod 13 is rotatably mounted on the connecting plate 12, the active bevel gear 14 is fixedly mounted on the rotating rod 13, the driven bevel gear 15 is fixedly mounted on the lifting screw rod 11, and the driven bevel gear 15 is meshed with the active bevel gear 14, and the fixed gear 16 is fixedly mounted on the lifting screw rod 11. It is fixedly installed on the end of the rotating rod 13 away from the active bevel gear 14, and an outer rack 17 and an inner rack 18 are fixedly installed on the mounting plate 1. The upper side wall of the fixed gear 16 cooperates with the outer rack 17, and the lower side wall of the fixed gear 16 cooperates with the inner rack 18. Through the design of the slider 10, when the lifting screw rod 11 rotates, the movable plate 8 can be driven to move relative to the fixed plate 7. At this time, the fixing or separation of the bamboo and wood ecological board can be achieved by changing the distance between the two. Through the cooperation of the active bevel gear 14 and the driven bevel gear 15, the rotation of the rotating rod 13 can be used to control the rotation of the lifting screw rod 11. Through the design of the outer rack 17 and the inner rack 18, when the device is used, the rotating disk 5 rotates counterclockwise ( Figure 1 As shown in the figure, the fixed gear 16 can meet the outer rack 17 and mesh with it. At this time, the rotating rod 13 drives the lifting screw 11 to rotate so that the movable plate 8 is close to the fixed plate 7 to complete the fixation of the bamboo and wood ecological board. After that, the rotating disk 5 continues to rotate so that the inner rack 18 meshes with the fixed gear 16. The rotating rod 13 drives the lifting screw 11 to reverse, so that the movable plate 8 is away from the fixed plate 7 to release the fixation of the bamboo and wood ecological board. In the process of the fixed plate 7 rotating in the distance between the outer rack 17 and the inner rack 18, the fixing effect of the bamboo and wood ecological board can be guaranteed. At this time, detecting its flatness can ensure the accuracy of the detection result.

[0037] The detection part is used to detect the overall flatness of the ecological board. The detection part includes a mounting rod 21 rotatably mounted on the mounting disk 1. A rotating shaft 19 is fixedly mounted on the side wall of the mounting rod 21 through a support rod 20. A rotating groove matching the rotating shaft 19 is opened on the side wall of the mounting disk 1, and a torsion spring 32 is provided between the rotating groove and the rotating shaft 19. The rotation direction of the mounting rod 21 can be limited by the cooperation between the rotating shaft 19 and the rotating groove. Under the action of the torsion spring 32, the mounting rod 21 can remain stable relative to the mounting disk 1 when not subject to external driving force, and can have a reset force when rotation occurs.

[0038] Two detection components are installed on the mounting rod 21, and the detection component includes a moving beam 22 fixedly installed on the mounting rod 21, and a detection mechanism is installed on the moving beam 22, and the detection mechanism consists of a moving screw 23, a moving groove, a moving block and a laser detector 24. The moving screw 23 is rotatably installed on the moving beam 22, the moving groove is opened on the moving beam 22, the moving block is slidably installed in the moving groove, and the moving block is threadedly connected to the moving screw 23, and the laser detector 24 is fixedly installed on the end of the moving block away from the moving beam 22. The laser detector 24 is an existing product, and the flatness detection process is realized by emitting laser and receiving the reflected light source. The specific working principle and structure are not elaborated here. The arrangement and fixing method of the fixed plate 7 and the movable plate 8 for the bamboo and wood ecological board can simultaneously perform inspection and processing on the front and back and the left and right sides of the bamboo and wood inspection board, meet the overall inspection requirements, and can better ensure the quality of subsequent products. In actual use, several top blocks with small intervals and arc-shaped sides can be set in the middle of the fixed plate 7 and the movable plate 8. The design of the top blocks can reduce the blocking area of ​​the bamboo and wood ecological board by the fixed plate 7 and the movable plate 8. Therefore, when two laser detectors 24 are used to detect the flatness of the bamboo and wood ecological board, the upper and lower surfaces of the bamboo and wood ecological board can also be inspected and processed at the same time, further improving the detection efficiency of the detection device. In order to prevent the blocking piece 33 from blocking the laser detector 24, a transparent material can be selected to prepare the blocking piece 33.

[0039] The rotating rod 13 is provided with a clamping mechanism matched with the mounting rod 21, and the clamping mechanism is composed of a clamping groove 26, a movable ring 27, a U-shaped rod 28 and a clamping rod 29. The clamping groove 26 is provided on the side wall of the mounting rod 21, the movable ring 27 is threadedly connected to the rotating rod 13, the U-shaped rod 28 is fixedly installed on the side wall of the movable ring 27, the clamping rod 29 is fixedly connected to the other end of the U-shaped rod 28, and the clamping rod 29 is matched with the clamping groove 26. When the fixed gear 16 is meshed with the external rack 17 to drive the rotating rod 13 to rotate, the threaded connection on the rotating rod 1 The movable ring 27 on 3 moves toward the direction approaching the mounting plate 1, thereby driving the clamping rod 29 to move and protrude from the fixed plate 7 through the U-shaped rod 28, and then the continued rotation of the rotating disk 5 will cause the clamping rod 29 to be clamped into the clamping groove 26. At this time, the rotation of the rotating disk 5 can drive the mounting rod 21 to rotate at the same time, and at this time, the two movable beams 22 are in a vertical state with the corresponding fixed plate 7, so the laser detector 24 and the bamboo and wood ecological board fixed on the fixed plate 7 are also in a vertical state, which can more accurately complete the flatness detection process.

[0040] A driving assembly that cooperates with the two detection mechanisms is installed on the mounting rod 21. The driving assembly consists of a round shaft, a belt transmission structure 25 and a driving gear 30. The round shaft is rotatably installed on the side wall of the mounting rod 21, and the belt transmission structure 25 is installed between the round shaft and the two movable screw rods 23. The driving gear 30 is fixedly installed on the end of the round shaft away from the mounting rod 21. A fixed rack 31 is fixedly installed on the mounting disk 1, and the driving gear 30 cooperates with the fixed rack 31. When the fixed plate 7 drives the mounting rod 21 to rotate together, the driving gear 30 meshes with the fixed rack 31 when the mounting rod 21 rotates a certain angle. At this time, the driving gear 30 rotates through the belt transmission structure 25 to drive the two movable screw rods 23 to rotate together, and then under the action of the two moving blocks, the two laser detectors 24 move along the moving beam 22 at the same time, thereby realizing all-round detection of the bamboo and wood ecological board.

[0041] The belt transmission structure 25 is composed of a pulley 1, a belt and two pulleys 2. The pulley 1 is fixedly mounted on the circular shaft, and the two pulleys 2 are respectively fixedly mounted on the corresponding moving screw rods 23. The belt is installed between the pulley 1 and the two pulleys 2. The diameter of the pulley 1 is larger than the diameter of the pulley 2. The advantage of the size design here is that the two moving screw rods 23 can rotate at a faster speed, so that the laser detector 24 can move smoothly along the moving beam 22. The fixed rack 31 is located between the outer rack 17 and the inner rack 18. The advantage of the position design here is that it can ensure that the rotation of the mounting rod 21 relative to the mounting disk 1 is within the period when the bamboo and wood ecological board is fixed between the fixed plate 7 and the moving plate 8, so it can be ensured. To verify the fixing effect of the bamboo and wood ecological board during the inspection process, when the fixed plate 7 moves to a position close to the inner rack 18, the meshing effect of the fixed gear 16 and the inner rack 18 causes the rotating rod 13 to rotate in the opposite direction. At this time, the clamping rod 29 moves to the end away from the mounting rod 21. Before the mounting rod 21 contacts the inner rack 18, the clamping rod 29 is separated from the clamping groove 26. Therefore, the force of the torsion spring 32 can make the mounting rod 21 reset and rotate, avoiding the contact between the mounting rod 21 and the inner rack 18 and causing motion interference. At the same time, during the reset and rotation of the mounting rod 21, the meshing effect of the fixed rack 31 and the driving gear 30 will cause the moving screw 23 to rotate in the opposite direction to reset and move the laser detector 24, so as to prepare for the next inspection.

[0042] A controller 34 is fixedly installed on the side wall of the mounting plate 1, and the controller 34 is electrically connected to the motor 4 and the laser detector 24. The controller 34 is an existing product, which can control the working conditions of the motor 4 and the laser detector 24, and can analyze the detection results of the laser detector 24 to determine the flatness of the bamboo and wood ecological board.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
