Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wood processing detection, in particular to a solid wood veneer joint detection device. Background Art
[0002] After coating the wood surface, the wear resistance and stain resistance of the wood can be increased, and the water penetration can be effectively prevented, so as to ensure that the wood is dry for a long time and does not deform, thereby extending the service life of the wood. The coated wood surface can resist scratches, stains and wear. Compared with the uncoated wood, it is more durable. Adding a layer of coating on the wood surface can enhance the aesthetics of the wood and make the wood color more vivid and bright. At present, the coating operation is mainly carried out by a coating machine. When the solid wood veneer is attached to the wood surface, the continuous solid wood veneer film is spliced by several lengths of solid wood veneer, so there is a splicing joint. In the industry standard, the splicing joint needs to be controlled at the cutting and processing position of the wood to avoid the splicing joint being located on the middle surface of the wood to affect the flatness of the wood. Therefore, the machine needs to be able to detect the position of the solid wood veneer splicing joint in time. At present, a color mark detection sensor is used to detect the splicing joint, but due to the different colors of the coating materials, it is easy to affect the detection accuracy of the color mark detection sensor, and there is a misjudgment situation, which urgently needs to be improved. Therefore, we propose a solid wood veneer splicing joint detection device. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Embodiment 1, as Figure 1-4 As shown, the utility model provides a technical solution: a solid wood veneer splicing joint detection device, including a bracket 1, a conveying roller 9, a pressure roller mechanism and a detection roller mechanism, the conveying roller 9 is rotatably installed on the inner side of the bracket 1, a crossbeam seat 2 is fixedly arranged on the top of the bracket 1, and a plurality of square holes are opened on the surface of the crossbeam seat 2, the pressure roller mechanism includes support columns 4 and pressure rollers 5 symmetrically distributed on the left and right sides of the detection roller mechanism, the pressure roller 5 is rotatably arranged at the bottom of the support column 4 through an axis and faces one side of the detection roller machine, the detection roller mechanism includes a column 6, a U-shaped frame 8, a detection roller 12, a metal sheet 11 and a metal detection sensor 10, the metal sheet 11 is fixed on the surface of the detection roller 12, the metal detection sensor 10 is connected to the U-shaped frame 8 through an L-shaped frame 13, the metal detection sensor 10 is vertically aligned with the position of the metal sheet 11, and the U-shaped frame 8 is fixed to the bottom of the column 6.
[0020] In a specific embodiment of the present invention, a metal detection sensor 10 is connected to a controller of a solid wood veneer laminating machine. The function of the solid wood veneer laminating machine to detect the position of a solid wood veneer joint is realized by detecting whether the metal detection sensor 10 detects a signal of a metal sheet 11. By detecting and identifying the position of the solid wood veneer joint, the position of the solid wood veneer joint is controlled to a position where processing and cutting are allowed, thereby reducing the loss of wood and solid wood veneer. The steps of device debugging are as follows: measuring the thickness of the solid wood veneer and the thickness of the solid wood veneer joint, and controlling the distance from the detection roller 12 to the pressure roller 5 between the thickness of the solid wood veneer and the thickness of the solid wood veneer joint, so that the solid wood veneer does not drive the detection roller 12 to rotate when passing through the detection roller 12, and when the solid wood veneer passes through the detection roller 12, the detection roller 12 is rotated. When the veneer joint passes through the detection roller 12, it quickly drives the detection roller 12 to rotate by friction, so that the metal sheet 11 passes through the metal detection sensor 10. The metal detection sensor 10 feeds back a signal to the solid wood veneer laminating machine controller, indicating that the joint has reached this point, thereby realizing the function of detecting the position of the solid wood veneer joint. The vertical position of the pressure roller 5 and the detection roller 12 is adjusted by bolts 13 and 27. When the bolts 13 and 27 are loosened, the vertical positions of the pressure roller 5 and the detection roller 12 can be adjusted. When the bolts 13 and 27 are tightened, the vertical positions of the pressure roller 5 and the detection roller 12 can be limited. In the initial state, the metal sheet 11 needs to be adjusted to a position close to the bottom of the metal detection sensor 10 probe (such as Figure 1 As shown), it is ensured that the metal detection sensor 10 can detect the metal sheet 11 in time.
[0021] In the preferred technical solution, both the pressure roller 5 and the detection roller 12 are rubber rollers. The two pressure rollers 5 and the detection rollers 12 are located directly above the conveying roller 9. The distances from the two pressure rollers 5 to the detection roller 12 are the same. The rubber rollers have a certain elasticity, and the pressure rollers 5 are adjusted to have sufficient frictional contact with the solid wood veneer.
[0022] In the preferred technical solution, the support column 4 is slidably connected with the square hole of the beam seat 2, and a bolt 3 for fastening the support column 4 is threadedly connected on the surface of the beam seat 2. The column 6 is slidably connected with the square hole at the center of the beam seat 2, and a bolt 7 for fastening the column 6 is threadedly connected on the surface of the beam seat 2. When the bolts are loosened, the vertical positions of the support columns 4 and 6 can be adjusted. When the bolts are tightened and in close contact with the surfaces of the support columns 4 and 6, the vertical positions of the support columns 4 and 6 can be limited.
[0023] In the preferred technical solution, the metal detection sensor 10 is connected through the L-shaped frame 13, and a thread is provided on the surface of the metal detection sensor 10. Nut 14 and nut 2 1401 are threadedly connected on the surface of the metal detection sensor 10. Nut 14 and nut 2 1401 are respectively located on the inner and outer sides of the L-shaped frame 13. Nut 14 and nut 2 1401 can adjust the distance from the metal detection sensor 10 to the detection roller 12, and are used to adjust the detection sensitivity of the metal detection sensor 10.
[0024] In the preferred technical solution, one end of the L-shaped frame 13 parallel to the metal detection sensor 10 is fixedly connected to an outer end surface of the U-shaped frame 8 by welding to ensure the installation stability of the L-shaped frame 13 and the metal detection sensor 10.
[0025] To sum up, this example provides a solution for physically detecting the position of the joints of solid wood veneer. Compared with traditional color mark sensors, this physical detection solution can avoid the influence of wood color on the misjudgment of the color mark sensor, thereby providing a solution for detecting applicable surface light and high detection accuracy. In addition, the metal detection sensor 10 has a lower cost than the color mark sensor, which can greatly reduce the company's cost of use.
