Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood panel processing technology, specifically to a processing device for furniture wood panels. Background Technology
[0002] In the furniture manufacturing process, it is usually necessary to polish and sand the cut wooden boards to remove burrs from the sides, making the surface smooth. This facilitates subsequent edge banding and installation, prevents burrs from injuring users during use, and enhances the overall aesthetics of the furniture. Chinese patent document CN211708951U discloses a sanding and polishing device for wooden furniture with adjustable and fixed dimensions. It is equipped with a first threaded rod, a fixing block, and a sliding groove, allowing the entire device to be fixed to the size of the wooden furniture, thus increasing the applicability of the sanding and polishing device. Simultaneously, it includes a frame and set bolts to keep the polishing head fixed on a horizontal line, ensuring consistent pressure and height during polishing, resulting in a more perfect surface finish. Furthermore, it includes a connecting rod, a sliding plate, and a second threaded rod, allowing the entire device to perform overall sanding and polishing of the wooden furniture surface without affecting the surface treatment, while also reducing the workload of the operator. However, the device can only polish the upper surface of the wood board and cannot effectively polish the side walls of the wood board. However, the burrs of the wood board after cutting are mainly concentrated on the side walls of the wood board. At the same time, when it is necessary to polish the side of the wood board after cutting, the device can only polish one side before processing the other side. This not only affects the processing efficiency, but also increases the labor cost of manual flipping. Utility Model Content
[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a processing device for furniture wood panels. This processing device can not only simultaneously grind and polish the side walls of the wood panels and eliminate burrs after cutting, but also effectively install and fix the wood panels during the grinding and polishing process, avoiding uniformity problems caused by wood panel displacement during processing.
[0004] The objective of this utility model is achieved through the following technical solution: A processing device for furniture wood panels includes a mounting platform, a movable support, a lifting slider, a pressing mechanism, and two sanding mechanisms. The main structure of the movable support is an inverted U-shaped structure, with auxiliary supports respectively provided on the inner walls of the two legs of the U-shaped structure. Both auxiliary supports are parallel to the crossbar of the U-shaped support. The mounting platform is positioned between the two auxiliary supports. The lifting slider is located between the mounting platform and the movable support and is an inverted convex structure. The bottom surface of the lifting slider is provided with a pressing mechanism corresponding to the mounting platform. The two sanding mechanisms are respectively provided on the bottom surfaces of the lifting slider on both sides of the auxiliary supports. Each sanding mechanism includes a connecting rod, a trapezoidal slider, a motor, and a sanding wheel. The top end of the connecting rod is fixedly connected to the bottom surface of the lifting slider. The trapezoidal slider is slidably positioned on the end face of the corresponding auxiliary support, with its inclined surface located on the side away from the mounting platform. The bottom end of the connecting rod is slidably engaged with the inclined surface of the corresponding trapezoidal slider. A motor is provided on the side of the trapezoidal slider closest to the mounting platform, and the motor output shaft is fixedly sleeved with the sanding wheel.
[0005] Based on further optimization of the above scheme, the bottom surface of the mounting platform and the bottom surface of the movable bracket are located on the same horizontal plane, and the bottom surface of the mounting platform is fixedly connected to the corresponding horizontal plane, while the bottom surface of the movable bracket is slidably connected to the corresponding horizontal plane; the bottom ends of the two legs of the movable bracket are respectively threaded through by two lead screws, and the top ends of the two legs of the movable bracket are respectively threaded through by two guide rods, and the lead screws and guide rods are parallel to each other.
[0006] Based on further optimization of the above scheme, a positioning protrusion is provided on one end face of the mounting platform to limit the position of the wooden board.
[0007] Based on further optimization of the above scheme, the end face of the lifting slider is connected to the bottom surface of the moving bracket through multiple telescopic rods, the number of telescopic rods is not less than two, and the multiple telescopic rods are evenly distributed around the central axis of the lifting slider.
[0008] Based on further optimization of the above scheme, the extrusion mechanism includes two slide plates, a positioning shaft and a roller. Slide grooves are opened on both sides of the bottom surface of the lifting slider and slide plates are slidably arranged in the slide grooves. The bottom ends of the two slide plates are fixedly connected by a positioning shaft and the outer wall of the positioning shaft is rotatably sleeved with the roller. The slide plates and the top of the corresponding slide grooves are connected by multiple compression springs.
[0009] Based on further optimization of the above scheme, the side of the trapezoidal slider away from the corresponding motor is connected to the inner wall of the corresponding movable bracket through a return spring.
[0010] Based on further optimization of the above scheme, the diameter of the grinding wheel is greater than the outer diameter of the motor and less than the height of the trapezoidal slider.
[0011] Based on further optimization of the above scheme, the height of the mounting platform is not less than the height of the auxiliary support.
[0012] The following are the technical effects of this utility model: This application utilizes the downward movement of a lifting slider to synchronously move the pressing mechanism downwards, thereby pressing the wooden board placed on the end face of the mounting table. This achieves pressing and positioning of the wooden board, preventing displacement due to friction during sanding and polishing. Furthermore, it eliminates the need for clamping the wooden board, facilitating installation and avoiding dead angles in side sanding and polishing caused by clamping. Simultaneously, the downward movement of the lifting slider synchronously moves two trapezoidal sliders closer together, accommodating wooden boards of different widths and ensuring the grinding wheel fits snugly against the side of the board. Then, a movable bracket moves along the mounting table to sand and polish both sides of the wooden board. This not only improves the efficiency of sanding and polishing the sides of the cut wooden board but also effectively prevents displacement of the wooden board during sanding and polishing, improving the precision and effect of the sanding and polishing process.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Example 1: A processing device for furniture wood panels includes a mounting platform 10, a movable support 20, a lifting slider 30, a pressing mechanism, and two sets of sanding mechanisms. The main structure of the movable support 20 is an inverted U-shaped structure (e.g., Figure 1 or Figure 2 As shown), and auxiliary supports (such as...) are respectively installed on the inner walls of the two legs of the U-shaped structure.

Both auxiliary supports are parallel to the crossbar of the U-shaped support (e.g., Figure 2As shown), the mounting platform 10 is positioned between two auxiliary supports; the bottom surface of the mounting platform 10 and the bottom surface of the movable support 20 (specifically, the auxiliary support) are on the same horizontal plane (this horizontal plane can be the ground or an operating table, depending on the specific situation; this embodiment does not impose many limitations), and the bottom surface of the mounting platform 10 is fixedly connected to the corresponding horizontal plane, while the bottom surface of the movable support 20 is slidably connected to the corresponding horizontal plane; the bottom ends of the two legs of the movable support 20 are respectively threaded through by two lead screws 22 (i.e., the movable support 20 is threadedly connected to the corresponding lead screw 22), and the top ends of the two legs of the movable support 20 are respectively threaded through by two guide rods 23 (i.e., the movable support 20 is slidably connected to the corresponding guide rod 23), and the lead screws 22 and guide rods 23 are parallel to each other (e.g., ...). Figure 2 As shown, the two lead screws 22 are located on the same horizontal plane, and the two guide rods 23 are located on the same horizontal plane; positioning brackets can be set on the front and rear sides of the mounting platform 10 for positioning the lead screws 22 and guide rods 23, and the lead screws 22 are rotatably connected to the corresponding positioning brackets. One end face of the mounting platform 10 (i.e., Figure 1 The lower left end face shown is provided with a positioning protrusion 11, which is used to limit the position of the wooden board.
[0018] The lifting slider 30 is located between the mounting platform 10 and the movable bracket 20, and the lifting slider 30 has an inverted convex structure (e.g., Figure 1 or Figure 2 As shown), the end face of the lifting slider 30 is connected to the bottom surface of the movable bracket 20 via multiple telescopic rods 21. The number of telescopic rods 21 is no less than two, and the multiple telescopic rods 21 are evenly distributed around the central axis of the lifting slider 30 (e.g., ...). Figure 1 As shown, in this embodiment, there are two telescopic rods 21, and the telescopic rods 21 can be hydraulic or electric. The specific drive type, model, and size can be determined according to actual conditions, and existing products in the field can be used. This embodiment does not impose excessive limitations. A pressing mechanism is provided on the bottom surface of the lifting slider 30 corresponding to the mounting platform 10. The pressing mechanism includes two sliding plates 41, a positioning shaft 42, and a roller 43. Slide grooves are respectively opened on both sides of the bottom surface of the lifting slider 30, and the sliding plates 41 are slidably arranged within the slide grooves (e.g., ...). Figure 1 or Figure 2 As shown, the two slide plates 41 are symmetrically arranged about the central axis of the lifting slider 30 and are parallel to each other. The bottom ends of the two slide plates 41 are fixedly connected by a positioning shaft 42 (that is, the two ends of the positioning shaft 42 are fixedly connected to the opposite sides of the two slide plates 41 respectively), and the outer wall of the positioning shaft 42 is rotatably sleeved with the roller 43. The slide plate 41 is connected to the top of the corresponding slide groove by multiple compression springs 410 (the number of compression springs 410 is determined according to the actual situation. Generally, 2 to 5 compression springs 410 are set on one slide plate 41 and the compression springs 410 are evenly distributed along the length direction of the corresponding slide plate 41).
[0019] Two grinding mechanisms are respectively installed on the bottom surfaces of the lifting slider 30 on both sides of the auxiliary support. Each mechanism includes a connecting rod 51, a trapezoidal slider 52, a motor 53, and a grinding wheel 54. The top end of the connecting rod 51 is fixedly connected to the bottom surface of the lifting slider 30. The trapezoidal slider 52 is slidably mounted on the end face of the corresponding auxiliary support (the auxiliary support is equipped with a sliding track corresponding to the trapezoidal slider 52, such as...). Figure 1 (As shown) and its inclined surface is located on the side away from the mounting platform 10. The bottom end of the connecting rod 51 is slidably engaged with the inclined surface of the corresponding trapezoidal slider 52. A motor 53 is installed on the side of the trapezoidal slider 52 closest to the mounting platform 10, and the output shaft of the motor 53 is fixedly sleeved with a grinding wheel 54 (for safety, a protective housing can be provided on the outer ring of the motor 53, and the grinding wheel 54 is located outside the protective housing). The side of the trapezoidal slider 52 away from the corresponding motor 53 is connected to the inner wall of the corresponding movable bracket 20 through a return spring 510 (as shown). Figure 1 (As shown). The diameter of the grinding wheel 54 is larger than the outer diameter of the motor 53 but smaller than the height of the trapezoidal slider 52. The height of the mounting platform 10 is not less than the height of the auxiliary support (set according to the actual situation, such as...). Figure 2 As shown, in this embodiment, the height of the mounting platform 10 is greater than the height of the auxiliary support.
[0020] Working principle: In use, the cut wooden board is first placed on the end face of the mounting platform 10, ensuring that one side of the board is in contact with the positioning protrusion 11. Initially, the moving bracket 20 is located at the positioning cam 11. Then, the lifting slider 30 is moved down by the telescopic rod 21. The lifting slider 30 drives the pressing mechanism down, so that the bottom end of the roller 43 contacts the end face of the wooden board. During this process, the lifting slider 30 uses the connecting rod 51 to synchronously drive the trapezoidal slider 52, the motor 53 and the grinding wheel 54 to move towards the side of the mounting platform 10 on the auxiliary bracket. When the bottom end of the roller 43 contacts the end face of the wooden board, the grinding wheel 54 has not yet contacted the side of the wooden board. As the lifting slider 30 continues to move down, due to the supporting force of the wooden board, the slide plate 41 slides in the corresponding groove, the compression spring 410 shortens, and the pressing force of the roller 43 is increased to ensure the stability of the positioning until the grinding wheel 54 contacts the corresponding side of the wooden board. Then, the grinding wheel 54 is started to rotate, and the rotation of the lead screw 22 is used to drive the moving bracket 20 to move along the mounting platform 10. The roller 42 rolls and squeezes on the end face of the wooden board to achieve grinding of the side of the wooden board.
[0021] Example 2: As a further optimization of the present utility model, based on the solution of embodiment 1, the end face of the mounting platform 10 is provided with a rubber layer with anti-slip particles. This is to prevent damage to the wooden board during the extrusion process of the extrusion mechanism and to further prevent the wooden board from shifting. At the same time, the roller 43 can also be wrapped with a rubber layer.
[0022] Example 3: As a further optimization of the present utility model, in order to ensure the smooth lifting of the lifting slider 30, based on the scheme of embodiment 1, the outer walls on both sides of the lifting slider 30 are respectively connected to the inner walls of the two legs of the corresponding movable bracket 20 through connecting blocks, and the connecting blocks are fixedly connected to the outer walls of the lifting slider 30 and slidably connected to the inner walls of the two legs of the movable bracket 20. Vertical grooves are opened on the inner walls of the two legs of the movable bracket 20 corresponding to the connecting blocks.
