Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to an intelligent furniture grinding and polishing machine. Background Technology

[0002] Furniture sanding and polishing is a core surface treatment process in furniture production, refurbishment, and maintenance. It is used to optimize the surface texture and appearance of furniture. It requires the use of sandpaper and soft cloth tools to gradually remove wood burrs, board splicing marks, old paint layers, or scratches, and to finely rub the surface. This not only enhances the surface gloss but also forms a protective film. This process is suitable for solid wood materials, giving new furniture a delicate and smooth texture, and can also repair surface wear on old furniture. It is a key step in improving the beauty, durability, and value of furniture.

[0003] Furniture sanding and polishing machines utilize a motor to drive the sanding disc and polishing wheel at high speed, enabling rapid processing of large furniture surfaces. This significantly reduces work time and physical labor, making them suitable for mass production or large-scale furniture renovation. By adjusting the speed and changing the abrasive, the sanding force and polishing precision can be precisely controlled, avoiding problems such as uneven sanding and color differences that occur with manual operation. This also meets diverse sanding and polishing needs while reducing dust splashing during manual sanding, thus improving the working environment.

[0004] Existing furniture sanding and polishing machines mostly use a rigid connection design for the grinding head and grinding disc, which lacks flexible adjustment margin and is difficult to adapt to the sanding and polishing needs of complex furniture surfaces. When processing furniture with curved surfaces, arcs, edges, or uneven textures, the rigidly connected grinding head and grinding disc cannot adapt to the surface contour and can only contact local flat surfaces. This results in inadequate sanding of concave or curved areas and over-sanding of raised areas, creating differences in surface flatness and affecting the uniformity of gloss after polishing. This design limitation also increases the difficulty of operation, requiring manual and repeated adjustments of the machine angle to cover complex areas, making it difficult to meet the refined processing needs of diverse furniture. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 An embodiment of this utility model is provided: a smart furniture grinding and polishing machine, including a grinding head 1 and a machine body 2. A torsion mechanism 3 is provided between the adjacent grinding head 1 and the machine body 2. The torsion mechanism 3 can realize the floating fit of the device on the furniture surface. A grinding and polishing mechanism 4 is provided at the bottom of the grinding head 1. The grinding and polishing mechanism 4 is used to grind and polish the furniture surface. The torsion mechanism 3 includes a base 31, the bottom of which is fixedly connected to the top of the grinding head 1. A joint ball 32 is fixedly connected to the top of the base 31. A ball sleeve 33 is fixedly connected to the bottom front side of the machine body 2. A plurality of ball holes 34 are opened on the inner wall of the ball sleeve 33. Small balls 35 are rotatably connected to the inner wall of the ball holes 34. A floating component 36 is provided at the bottom of the grinding head 1. Specifically, the base 31 of the torsion mechanism 3 is fixedly connected to the top of the grinding head 1, and a joint ball 32 is fixedly connected to the top of the base 31. A ball sleeve 33 is fixedly connected to the front bottom of the body 2. Multiple ball holes 34 are opened on the inner wall of the ball sleeve 33, and small balls 35 are rotatably connected to the inner wall of the ball holes 34. When the grinding head 1 needs to automatically fit and adjust the angle according to the surface shape of the furniture, the joint ball 32 can rotate in multiple directions and angles within the ball sleeve 33. At the same time, the small balls 35 rotate synchronously within the ball holes 34 along with the movement of the joint ball 32, providing support and force transmission for the joint ball 32. Through the movement cooperation between the joint ball 32 and the ball sleeve 33, and the rotation cooperation between the small balls 35 and the ball holes 34, the frictional resistance between the joint ball 32 and the ball sleeve 33 is reduced, achieving smooth operation of the torsion mechanism 3. The floating component 36 at the bottom of the grinding head 1 is closed. During its movement, the articulated ball 32 remains in contact with the furniture surface. As the furniture surface undulates, the floating component 36 can extend, retract, or adjust its angle accordingly, further enhancing the adaptability of the polishing mechanism 4 to the undulations of the furniture surface. Through the adaptive adjustment of the floating component 36 and the multi-directional movement of the articulated ball 32 and the ball sleeve 33, the polishing head 1 is floated and adhered to the furniture surface, improving the working efficiency of the polishing mechanism 4. Once the polishing head 1 is stably floated and adhered to the furniture surface through the torsion mechanism 3 and the floating component 36, the polishing mechanism 4 starts. Driven by the polishing head 1, the polishing mechanism 4 maintains a close fit with the furniture surface and operates at high speed. Through the high-speed operation of the polishing mechanism 4 and the floating fit between the polishing head 1 and the furniture surface, uniform polishing of the furniture surface is achieved, ensuring the flatness and smoothness of the furniture surface after polishing.

[0020] Reference Figures 2-4 The grinding and polishing mechanism 4 includes multiple grinding discs 41. The tops of the multiple grinding discs 41 are all located at the bottom of the same grinding head 1. Multiple motors 42 are fixedly connected to the inner wall of the grinding head 1. Universal shaft 43 is rotatably connected to the bottom of the multiple motors 42. A connecting block 44 is rotatably connected to the inner wall of the bottom of the multiple universal shaft 43. Universal shaft 45 is rotatably connected to the bottom of the outer wall of the multiple connecting block 44. Screws 46 are threadedly connected to the bottom of the multiple grinding discs 41. The tops of the multiple screws 46 are threadedly connected to the inner wall of the bottom of the multiple universal shafts 45 respectively. Specifically, when the grinding and polishing mechanism 4 starts operation, it first activates multiple motors 42 fixedly connected to the inner wall of the grinding head 1. Through the power output of the motors 42 and their rotational connection with universal joint 43, initial power transmission is achieved from the motors 42 to the universal joint 43. After receiving the power from the motors 42, the multiple universal joints 43 begin to rotate. Through the rotation of the universal joints 43 and their rotational connection with the connecting block 44, further power transmission is achieved from the universal joints 43 to the connecting block 44. The multiple connecting blocks 44, after receiving the power from the universal joints 43, rotate accordingly. Through the rotation of the connecting blocks 44 and their rotational connection with the second universal joint 45, continuous power transmission is achieved from the connecting block 44 to the second universal joint 45. After receiving power from the connecting block 44, shaft 2 45 rotates. Since the tops of multiple screws 46 are threadedly connected to the bottom inner walls of multiple universal shafts 2 45, and the bottoms of multiple screws 46 are threadedly connected to the bottoms of multiple grinding discs 41, the power is ultimately transmitted from universal shaft 2 45 to grinding discs 41 through the rotation of universal shaft 2 45 and the threaded connection of screws 46. When the device moves on the furniture surface, the grinding discs 41 adhere to the working surface and change angle. Universal shaft 2 45 changes angle synchronously. At this time, the connecting block 44 still maintains the transmission of power, so that the grinding discs 41 can continue to rotate and work. Through the rotation of multiple grinding discs 41 and the contact between the grinding discs 41 and the target workpiece, the grinding and polishing mechanism 4 performs grinding and polishing operations on the target workpiece.

[0021] Reference Figures 1-3The floating assembly 36 includes multiple floating disks 361, the tops of which are fixedly connected to the bottom of the same grinding head 1. Soft rings 362 are fixedly connected to the bottom outer walls of the multiple floating disks 361, and floating disks 363 are fixedly connected to the bottoms of the multiple soft rings 362. Shaft holes 364 are opened at the bottoms of the multiple floating disks 363. The torsion mechanism 3 also includes a guard plate 37, the front side of which is fixedly connected to the rear side of the grinding head 1. The rear outer edge of the guard plate 37 adopts an arc design, and the rear bottom of the guard plate 37 is rounded and smooth. The grinding and polishing mechanism 4 also includes multiple heat dissipation grilles 47, which are respectively fixedly connected to the outer wall of the grinding head 1. The inner edges of the multiple heat dissipation grilles 47 are rounded. Specifically, during the grinding and polishing operation of the grinding head 1, the tops of multiple floating disks 361 in the floating assembly 36 are fixedly connected to the bottom of the grinding head 1. Soft rings 362 are fixedly connected to the bottom outer walls of the multiple floating disks 361, and floating disks 363 are fixedly connected to the bottoms of the multiple soft rings 362. Shaft holes 364 are provided at the bottoms of the multiple floating disks 363. Through the fixed connection between the floating disks 361 and the soft rings 362, and the fixed connection between the soft rings 362 and the floating disks 363, the grinding head 1 achieves floating adaptation during operation, ensuring that the grinding head 1 can adjust its angle according to the unevenness of the furniture surface, further improving the adaptability of the device. Simultaneously, the shaft holes 364 allow the universal shaft 45 to pass through the interior of the floating disks 363, ensuring power transmission. The front side of the guard plate 37 in the torsion mechanism 3 is fixedly connected to... Attached to the rear side of the grinding head 1, the outer edge of the rear side of the guard plate 37 is designed with an arc shape, and the bottom of the rear side of the guard plate 37 is treated with rounded corners. Through the fixed connection between the guard plate 37 and the grinding head 1, as well as the arc-shaped outer edge and rounded bottom design of the rear side of the guard plate 37, the rear structure of the grinding head 1 is prevented from colliding with external objects during operation, which could damage the device. It also protects the operator from the injury caused by flying debris during grinding and polishing. Multiple heat dissipation grilles 47 in the grinding and polishing mechanism 4 are fixedly connected to the outer wall of the grinding head 1. The inner wall edges of the multiple heat dissipation grilles 47 are treated with rounded corners. Through the fixed connection between the heat dissipation grilles 47 and the grinding head 1, as well as the rounded corner treatment of the inner wall edges of the heat dissipation grilles 47, the heat of the grinding head 1 is dissipated outward during operation, while avoiding scratches to the operator caused by the heat dissipation grilles 47.

[0022] Reference Figures 4-5 The top and bottom of the outer wall of the multiple grinding discs 41 are rounded. The outer wall of the multiple grinding discs 41 is made of polyester fiber material. A handle 5 is fixedly connected to the rear side of the machine body 2, and a handle 6 is fixedly connected to the right side of the machine body 2. The outer walls of the handles 5 and 6 are both designed with a wave strip. A wiring sleeve 7 is fixedly connected to the rear side of the handle 5. Multiple electrodes 8 are fixedly connected to the rear side of the inner wall of the wiring sleeve 7. The outer wall of the wiring sleeve 7 is designed with a thread. Specifically, the operator connects the device to an external power supply structure via the wiring sleeve 7 to provide power to the device. After the external power supply line is connected, it first forms a circuit connection with multiple electrodes 8 fixedly connected to the rear side of the inner wall of the wiring sleeve 7. Through the external power supply line and the multiple electrodes 8, power is supplied to the electrical components inside the device. Then, the operator aligns the connection structure of the external power supply line with the threaded structure on the outer wall of the wiring sleeve 7 and rotates it in to complete the tight connection and fixation of the circuit. Subsequently, the external equipment begins to supply power. After the circuit connection and supply operation is completed, the operator holds handle 5 with their right hand and handle 6 with their left hand, according to the work requirements. The outer walls are all designed with corrugated strips. The operator can achieve stable control of the device by contacting and holding the corrugated strips with their hands. When operating the device, the operator can align the multiple grinding discs 41 with the workpiece to be ground. The outer walls of the multiple grinding discs 41 are made of polyester fiber material, which has high hardness, good flatness, and can increase the contact area with the furniture surface. The top and bottom of the outer walls of the grinding discs 41 are rounded to improve the smoothness of the device's movement during grinding and polishing operations. After the device is started, the multiple grinding discs 41 rotate around their own axis. The grinding operation of the furniture surface is achieved by the contact between the rotating multiple grinding discs 41 and the workpiece to be ground.

[0023] Working principle: The operator first connects the device to the external power supply structure through the wiring sleeve 7 on the device to supply the power required for the device to work. When the external power supply line is connected, it needs to form a stable circuit connection with the multiple electrodes 8 fixedly connected to the rear side of the inner wall of the wiring sleeve 7. Through the cooperation of the external power supply line and the multiple electrodes 8, a path for transmitting power to the electrical components inside the device is built. Then, the operator aligns the connection structure of the external power supply line with the thread structure on the outer wall of the wiring sleeve 7, and completes the tight connection and mechanical fixation of the circuit by rotating and inserting it to ensure the stability of the line connection during the power supply process and avoid the interruption of device operation due to poor contact. After the power supply connection is completed, the operator uses both hands to operate the device according to the work requirements. The right hand holds handle 5 on the device and the left hand holds handle 6. The outer walls of handle 5 and handle 6 are both designed with a wave strip. This design can increase the friction between the operator's hand and the handle, and at the same time improve the comfort when holding it, so as to achieve stable operation of the device by the operator and prevent the device from slipping out of control during the operation. The operator manipulates the device to align multiple grinding discs 41 in the polishing mechanism 4 with the surface of the furniture workpiece to be polished. The outer walls of the grinding discs 41 are made of polyester fiber material, which has high hardness and good flatness, effectively increasing the contact area between the grinding discs 41 and the furniture surface, ensuring uniform polishing. At the same time, the top and bottom of the outer walls of the grinding discs 41 are rounded, which reduces the resistance between the grinding discs 41 and the furniture surface when the device moves during operation, improving the smoothness of the device's movement. After the grinding discs 41 are aligned with the workpiece, the device enters the angle adaptation and floating contact stage. The bottom of the base 31 of the torsion mechanism 3 is fixedly connected to the top of the grinding head 1. A joint ball 32 is fixedly connected to the top of the base 31, and a ball sleeve 33 adapted to the joint ball 32 is fixedly connected to the front bottom of the device body 2. The inner wall of the ball sleeve 33 has multiple ball holes 34, and a small ball 35 is rotatably connected to the inner wall of each ball hole 34. When the grinding head 1 needs to automatically fit and adjust the angle according to the shape of the furniture surface, the joint ball 32 can rotate in multiple directions and angles within the ball sleeve 33. At the same time, the small ball 35 rotates synchronously within the ball hole 34 along with the movement of the joint ball 32. The small ball 35 not only provides support for the joint ball 32, but also reduces the frictional resistance between the joint ball 32 and the ball sleeve 33 through its own rotation, ensuring the smoothness of the torsion mechanism 3's operation. Meanwhile, the floating component 36 at the bottom of the grinding head 1 remains in contact with the furniture surface during the movement of the articulated ball 32. The tops of multiple floats 361 are fixedly connected to the bottom of the grinding head 1. A soft ring 362 is fixedly connected to the bottom outer wall of each float 361. A second float 363 is fixedly connected to the bottom of the soft ring 362. The bottom of the second float 363 has a shaft hole 364. Through the fixed connection between the first float 361 and the soft ring 362, and between the soft ring 362 and the second float 363, the soft ring 362 can move according to... The furniture surface undergoes corresponding deformation due to undulations, causing the second floating plate 363 to extend, retract, or adjust its angle, thereby enabling the grinding head 1 to float and adapt during operation. This ensures that the grinding head 1 can closely fit the furniture surface, further enhancing the adaptability of the polishing mechanism 4 to the undulations of the furniture surface. At the same time, the shaft hole 364 at the bottom of the second floating plate 363 allows the universal shaft 45 in the polishing mechanism 4 to pass through the inside of the second floating plate 363, providing a structural channel for subsequent power transmission to the polishing disc 41 and preventing the floating component 36 from obstructing power transmission. After the motor 42 of the grinding and polishing mechanism 4 is started, the power output end of the motor 42 is connected to the rotation of the universal joint 43, realizing the initial transmission of power from the motor 42 to the universal joint 43. After receiving the power, the multiple universal joints 43 begin to rotate and further transmit the power to the connecting block 44. The connecting block 44 rotates synchronously with the power input, and then the power is continuously transmitted to the universal joint 45 through the rotational connection of the connecting block 44 to the universal joint 45. Since the tops of the multiple screws 46 are respectively threaded to the bottom inner walls of the multiple universal joints 45, and the bottoms of the screws 46 are respectively threaded to the bottoms of the multiple grinding discs 41, the rotation of the universal joint 45 can be achieved through... The threaded connection of screw 46 transmits power to the polishing disc 41, driving it to rotate around its own axis. As the device moves along the furniture surface, the polishing disc 41 will conform to the surface of the workpiece and change angles. At this time, the universal shaft 2 45 can change its angle synchronously. The connecting block 44 can maintain stable power transmission even when the angles of universal shaft 1 43 and universal shaft 2 45 change, ensuring that the polishing disc 41 is always in a rotating working state. Through the contact friction between the multiple rotating polishing discs 41 and the surface of the furniture workpiece, the polishing mechanism 4 achieves uniform polishing of the furniture surface, ensuring the flatness and smoothness of the furniture surface after polishing. Throughout the grinding and polishing process, the protective and heat dissipation structures of the device function simultaneously. The front of the guard plate 37 in the torsion mechanism 3 is fixedly connected to the rear of the grinding head 1. The outer rear edge of the guard plate 37 features an arc design, and the bottom of the rear edge is rounded and smooth. Through the fixed connection between the guard plate 37 and the grinding head 1, the arc-shaped outer edge effectively prevents damage to the device caused by collisions between the rear structure of the grinding head 1 and external objects during operation. Simultaneously, the combination of the rounded bottom and the arc-shaped edge prevents sawdust, dust, and other flying debris generated during grinding and polishing from spreading towards the operator, protecting the operator from injury. Multiple heat dissipation grilles 47 in the polishing mechanism 4 are fixedly connected to the outer wall of the grinding head 1, and the inner wall edge of the heat dissipation grille 47 is rounded. Since the motor 42 generates heat during operation, the internal temperature of the grinding head 1 rises. The heat dissipation grille 47 can dissipate the internal heat of the grinding head 1 to the external environment through the grille structure, preventing the motor 42 and other electrical components from overheating and being damaged due to excessive internal temperature, and ensuring the continuous and stable operation of the device. At the same time, the rounded edge of the inner wall can prevent the operator from being scratched by the edge of the heat dissipation grille 47 when holding the device or approaching the grinding head 1, thus improving the safety of the device operation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
