Description

Technical Field

[0001] This utility model relates to the field of rattan furniture processing technology, specifically a rattan furniture frame polishing machine. Background Technology

[0002] Rattan furniture, with its unique natural texture and artistic charm, is deeply loved by consumers. In the processing of rattan furniture, the frame is a crucial part of the overall structure. The quality of the frame directly affects the stability and durability of the furniture. Polishing, as an important post-processing step, improves the surface smoothness of the frame, making it not only comfortable to the touch but also enhancing its aesthetics, laying a solid foundation for subsequent weaving and the final product.

[0003] Utility model patent application number CN202223348636.4 discloses a polishing tool for rattan furniture frames. This tool includes a support component and two mounting brackets. The two mounting brackets are symmetrically mounted on top of the support component, which supports the wooden frame to be polished. Each mounting bracket has a side groove on an opposite side. Two drive rollers are symmetrically rotatably connected inside each side groove. A drive belt is sleeved between the two drive rollers. A sanding belt is adhered to the outside of the drive belt. A second motor drives a second output shaft to rotate, which in turn drives the drive rollers to rotate. The drive rollers then move the drive belt, which in turn moves the sanding belt. The sanding belt polishes the surface of the wooden frame, allowing for complete polishing of the wooden frame in a shorter time, thus improving the polishing efficiency.

[0004] While the aforementioned device improves the polishing efficiency of wooden frames, it still presents the following problems in practical use: Specifically, during polishing, the worker must hold the wooden frame between two sanding belts and manually push it to achieve overall sanding. This method not only consumes a lot of manpower and increases labor intensity, but also poses a safety risk due to the worker's close contact with the moving parts. Therefore, we propose a rattan furniture frame polishing machine. Utility Model Content

[0043] 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.

[0044] This embodiment provides a technical solution:

[0045] Please see Figures 1-2 As shown, a rattan furniture frame polishing machine includes a base 1;

[0046] With the above configuration, the base 1 serves as the basic support structure for the entire polishing machine, providing an installation reference for the polishing section 2 and the positioning guide section 3.

[0047] In this embodiment, a notch 11 is provided at the top of the base 1, and a double-ended lead screw 13 is rotatably installed inside the notch 11. The threads at both ends of the double-ended lead screw 13 have opposite directions of rotation. A first motor 12 for driving the double-ended lead screw 13 to rotate is installed at the right end of the base 1. This design can drive the connecting blocks 24 of the polishing sections 2 on both sides to move in opposite directions, realizing precise and symmetrical adjustment of the spacing of the polishing belts 22, adapting to different specifications of rattan furniture frames, and improving the versatility of the equipment.

[0048] In this embodiment, guide rods 14 are fixed at both the front and rear sides of the notch 11, and the ends of the guide rods 14 are fixedly connected to the inner wall of the notch 11 by bolts. When the double-ended lead screw 13 drives the movable frame 20 to move, the guide rods 14 play a guiding and stabilizing role, restricting the connecting block 24 to only move in a straight line, preventing the polishing belt 22 from deviating during the adjustment process, and ensuring the stability and reliability of the polishing operation.

[0049] In this embodiment, support blocks 10 are fixedly connected to the bottom of the base 1 on both the front and rear sides by bolts. The cross-sectional shape of the support blocks 10 is T-shaped. The T-shaped support blocks 10 are fixed by bolts, which increases the contact area between the equipment and the ground, effectively disperses the pressure when the equipment is running, enhances the overall stability of the polishing machine, reduces positional displacement caused by vibration during polishing, ensures polishing accuracy, and extends the service life of the equipment.

[0050] Please see Figure 1 , Figure 3and Figure 4 As shown, two symmetrical polishing sections 2 are installed on the left and right sides of the top of the base 1, respectively, and are used for polishing the rattan furniture frame. Each section includes two symmetrically arranged polishing belts 22 with adjustable spacing. Each polishing belt 22 has a movable frame 20 on one side, with each of the two opposite ends of the movable frames 20 being open. The polishing belt 22 is installed within the openings of the movable frames 20. Two rollers 21 are also rotatably installed within the openings of the movable frames 20, and the polishing belt 22 is fitted over the outside of the two rollers 21. A second motor 23 for driving the rollers 21 is installed on the top of the movable frames 20. A connecting block 24 is fixed to the bottom of the movable frames 20. A double-ended lead screw 13 passes through the connecting block 24 and is threadedly connected to it. A guide rod 14 passes through the connecting block 24 and is slidably connected to it. This design ensures that the movable frames 20 can be flexibly adjusted in position, while ensuring the smooth operation of the polishing belts 22, providing a continuous and uniform polishing effect for the frame.

[0051] With the above configuration, the symmetrically arranged and adjustable-spacing polishing belts 22 on both sides can flexibly adapt to rattan furniture frames of different sizes, meeting diverse processing needs. By adjusting the spacing of the polishing belts 22, uniform and effective polishing of frames of different thicknesses can be ensured, improving equipment versatility and processing efficiency, and reducing costs incurred due to equipment replacement.

[0052] In this embodiment, the polishing belt 22 moves in the opposite direction to the movement of the rattan furniture frame. This design generates a greater relative speed when the two come into contact, enhancing the polishing effect. This reverse movement allows the polishing belt 22 to work more fully on the frame surface, effectively removing imperfections such as protrusions and burrs, and improving surface smoothness.

[0053] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, two symmetrical positioning guides 3 are respectively installed on the front and rear sides of the polishing section 2 and are used to transport and guide the rattan furniture frame; including a bracket 30 detachably connected to the base 1, the bracket 30 is U-shaped, the bottom of the bracket 30 is open, a first conveying wheel 33 is rotatably installed in the lower part of the bottom opening of the bracket 30, and the outer wall of the first conveying wheel 33 has a first clamping groove; a U-shaped mounting frame 35 is slidably installed in the upper part of the opening of the bracket 30, a second conveying wheel 36 is rotatably installed in the bottom opening of the mounting frame 35, and the outer wall of the second conveying wheel 36 has a second clamping groove, and the first clamping groove and the second clamping groove are used to clamp the rattan furniture frame so as to drive the rattan furniture frame to move horizontally through the first conveying wheel 33 and the second conveying wheel 36; a drive assembly for adjusting the height of the mounting frame 35 is also installed on the top of the bracket 30; the drive assembly includes a threaded rod 37 rotatably installed at the bottom of the mounting frame 35, the threaded rod 37 passes through the top of the bracket 30 and is threadedly connected to the bracket 30; a handwheel 38 is coaxially keyed to the top of the threaded rod 37. The height of the mounting bracket 35 can be manually adjusted by rotating the handwheel 38 to drive the threaded rod 37. This structure is easy to operate and allows for flexible adjustment of the position of the second conveyor wheel 36 according to the thickness of the frame, ensuring that the first and second conveyor wheels can stably clamp and convey frames of different specifications. A third motor 32 for driving the first conveyor wheel 33 to rotate is installed on the right end face of the bracket 30; guide frames 34 are fixed on the front and rear walls of the bracket 30, and guide holes 340 are opened at the guide frames 34 to guide the rattan furniture frame.

[0054] Through the above-described configuration, the automatic conveying and precise positioning of the rattan furniture frame is achieved through the coordinated structure of the bracket 30, the first conveying wheel 33, and the second conveying wheel 36. The third motor 32 drives the first conveying wheel 33 to rotate, thereby moving the frame. The guide hole 340 assists in guidance, and the drive component adjusts the height of the mounting bracket 35 to adapt to different frames. This not only reduces the intensity of manual operation and safety risks but also ensures stable conveying of the frame during polishing, improving polishing quality and consistency.

[0055] Please see Figure 1 and Figure 6 As shown, in this embodiment, mounting blocks 31 are fixed at the bottom of both the left and right side walls of the bracket 30. Two fixing holes 310 are provided on the mounting blocks 31, and connecting bolts threaded into the base 1 are inserted through the fixing holes 310. By fixing the positioning guide 3 to the base 1 with the connecting bolts, a detachable connection between the positioning guide 3 and the base 1 is achieved. This design facilitates the assembly, disassembly, and maintenance of the equipment, and allows the installation position of the positioning guide 3 to be adjusted according to actual needs, enhancing the flexibility of equipment use.

[0056] In this embodiment, the guide hole 340 has a funnel-shaped cross-section, and its opening is wider at the front and narrower at the back. The funnel shape and width of the guide hole 340 facilitates the quick and accurate insertion of the rattan furniture frame, reducing manual alignment time and improving material loading efficiency.

[0057] In this embodiment, two guide rails 300 are fixed to the top of each of the two inner side walls of the bracket 30's opening, and guide grooves that slide in connection with the guide rails 300 are provided on the two side walls of the mounting frame 35. The guide rails 300 provide precise guidance for the lifting and lowering of the mounting frame 35, ensuring that the second conveying wheel 36 lifts and lowers vertically and avoiding swaying.

[0058] It should be added that the first conveyor wheel 33 is located directly above the second conveyor wheel 36, and the cross-sectional shape of both the first and second clamping grooves is arc-shaped. The arc-shaped clamping grooves fit snugly against the cylindrical skeleton, increasing the contact area, improving clamping stability, ensuring that the skeleton does not slip during conveying, and achieving efficient and stable polishing operations.

[0059] It is worth noting that the first motor 12, the second motor 23, and the third motor 32 in this embodiment are existing conventional technologies, and will not be described in detail here.

[0060] Before grinding the frame, the user first holds and rotates the handwheel 38. The handwheel 38 drives the threaded rod 37 to rotate. Since the threaded rod 37 is rotatably connected to the mounting frame 35 and threadedly connected to the bracket 30, according to the principle of screw transmission, the threaded rod 37 will drive the mounting frame 35 to move downward in the vertical direction, so that the second conveyor wheel 36 in the bottom opening of the mounting frame 35 descends synchronously. Conversely, if the handwheel 38 is rotated counterclockwise, the threaded rod 37 will rotate counterclockwise, and the mounting frame 35 and the second conveyor wheel 36 will move upward. When the second conveyor wheel 36 moves to a suitable height, the user stops rotating the handwheel 38.

[0061] When polishing the frame, the user first guides the rattan furniture frame through the funnel-shaped guide hole 340 on the guide frame 34, which is wider at the front and narrower at the back. The frame is then placed between the first conveyor wheel 33 and the second conveyor wheel 36. The user then starts the third motor 32, which drives the first conveyor wheel 33 to rotate. Due to the clamping effect of the first conveyor wheel 33 and the second conveyor wheel 36, the frame moves horizontally. At the same time, the user starts the first motor 12, which drives the double-ended lead screw 13 in the notch 11 to rotate. Since the threads at both ends of the lead screw 13 rotate in opposite directions, the connecting block 24, which is threaded to the double-ended lead screw 13, drives the movable frame 20 of the polishing parts 2 on both sides to move along the guide rods 14 fixed on the front and rear sides of the notch 11 towards one side of the frame. When the polishing strips 22 on both sides contact the frame, the user immediately stops the power supply to the first motor 12. At this time, the user turns on the power of the second motor 23, and the second motor 23 starts to work. The output shaft of the second motor 23 drives the roller 21 to rotate, so that the polishing belt 22 sleeved on the outside of the roller 21 forms a cycle. Since the movement direction of the polishing belt 22 is opposite to the movement direction of the frame, the outer wall of the frame can be polished.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
