Description

Technical Field

[0001] This invention relates to the field of furniture spraying technology, specifically a rotating hanger for spraying solid wood furniture. Background Technology

[0002] In the production of solid wood furniture, surface coating is a crucial process, as its quality directly affects the furniture's aesthetics, durability, and environmental performance. Traditional coating methods often involve manual hand-held spray guns applied to fixed furniture. This method has several drawbacks: First, operators need to constantly change positions and angles, resulting in high labor intensity and low efficiency; second, due to human factors, uneven coating thickness, missed areas, or runs are easily caused, severely impacting product quality; third, for furniture with complex structures (such as parts with carvings or grooves), fixed spraying cannot cover all surfaces, creating coating dead zones.

[0003] Current spray painting hangers have relatively simple structures, and their clamping mechanisms are usually fixed or manually adjustable. They cannot adapt to solid wood furniture workpieces of different sizes and shapes. The clamping process is cumbersome and can easily damage the workpiece surface. In addition, some equipment lacks an effective waste recycling system during the spraying process, resulting in excess paint mist and dripping paint splashing everywhere. This not only pollutes the workshop environment and increases the difficulty of cleaning, but may also harm the health of operators. Therefore, we propose a rotating hanger for spraying solid wood furniture. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The present invention discloses a rotating hanger for spraying solid wood furniture, comprising a base, a support frame fixedly connected to one side of the base, a hanger fixedly connected to the upper side of the support frame, sliding frames symmetrically slidably connected to both ends of one side of the hanger, a rotating disk rotatably connected to the inner side of each of the two sliding frames, and a sliding groove equally spaced around one side surface of the rotating disk, with a slider slidably connected inside the sliding groove.

[0007] As a preferred embodiment of the present invention, a geared motor is fixedly installed on the outer side of one end of the hanger. The output end of the geared motor is connected to a bidirectional lead screw through the hanger via a coupling. Both ends of the bidirectional lead screw are threaded with threaded blocks on their outer circumferences, and one side of the threaded blocks is fixedly connected to the sliding frame.

[0008] As a preferred embodiment of the present invention, a guide rail is provided on one side of the hanger, and the inside of the guide rail is slidably connected to a threaded block. A rotary motor is fixedly installed on the outside of one of the sliding frames, and the output end of the rotary motor is connected to the rotary disk via a coupling.

[0009] As a preferred embodiment of the present invention, an electric push rod is fixedly embedded in the center end of the base, and the output end of the electric push rod is fixedly connected to a placement platform.

[0010] As a preferred embodiment of the present invention, a collection box is slidably connected to one side of the base, and blocks are fixedly connected to the four sides of the base. Several leakage holes are provided at the upper end of the base.

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] Example: Figures 1-4 As shown, the present invention provides a rotating hanger for spraying solid wood furniture, comprising a base 1, a support frame 2 fixedly connected to one side of the base 1, a hanger 3 fixedly connected to the upper side of the support frame 2, sliding frames 4 symmetrically slidably connected to both ends of one side of the hanger 3, a rotating disk 5 rotatably connected to the inner side of each of the two sliding frames 4, and grooves 6 evenly spaced around one side surface of the rotating disk 5, with sliders 7 slidably connected inside the grooves 6.

[0016] The rotating disk 5 houses a servo motor 8, whose output is connected to a drive disk 9 via a coupling. The drive disk 9 is also secured with fixed lugs 10 at equal intervals around its perimeter. The servo motor 8's internal design within the rotating disk 5 results in a more compact overall structure, saving external space. Furthermore, the servo motor offers advantages such as high precision, fast response, and accurate control of angle and torque, providing crucial assurance for the accuracy and reliability of subsequent clamping actions.

[0017] One side of the fixed ear 10 is rotatably connected to a push rod 11, and the outer end of the push rod 11 is rotatably connected to one end of the slider 7. The other end of the slider 7 passes through the slide groove 6 and is fixedly connected to a clamping block 12. Through the cooperation of the fixed ear 10, the push rod 11, and the slider 7, the rotational motion of the servo motor 8 is cleverly converted into the radial linear motion of the clamping block 12. This allows multiple clamping blocks 12 to move synchronously towards the center or centrifugally, achieving self-centering and uniform clamping of the workpiece. This effectively avoids workpiece deformation or damage caused by uneven force at a single point, and is especially suitable for irregularly shaped solid wood furniture.

[0018] Among them, a geared motor 13 is fixedly installed on the outer side of one end of the hanger 3. The output end of the geared motor 13 is connected to a double-acting screw 14 through the hanger 3 via a coupling. Both ends of the double-acting screw 14 are threaded with threaded blocks 15, and one side of the threaded blocks 15 is fixedly connected to the sliding frame 4. By using the geared motor 13 in conjunction with the double-acting screw 14, the opposing or opposite movements of the two sliding frames 4 can be controlled synchronously and precisely with a single power source. This ensures the high synchronicity of the actions of the clamping mechanisms on both sides, guarantees the centering of the workpiece during clamping and spraying, and improves the stability and operational accuracy of the equipment.

[0019] The hanger 3 has a guide rail 16 on one side, and the inside of the guide rail 16 is slidably connected to the threaded block 15. A rotary motor 21 is fixedly installed on the outside of one of the sliding frames 4, and the output end of the rotary motor 21 is connected to the rotary disk 5 through a coupling. The guide rail 16 provides a stable guide for the movement of the threaded block 15 and the sliding frame 4, effectively preventing them from swaying or jamming during operation, and ensuring smooth and stable movement.

[0020] An electric push rod 17 is fixedly embedded in the center of the base 1. The output end of the electric push rod 17 is fixedly connected to a placement platform 18. The placement platform 18, driven by the electric push rod 17, facilitates the loading and unloading of workpieces. Before clamping, the placement platform 18 rises to support the workpiece, making it easy for manual or robotic arm placement. After clamping, the placement platform 18 lowers, completely suspending the workpiece in the air, avoiding obstruction of the spraying surface by the support and ensuring no blind spots in the spraying.

[0021] The base 1 has a collection box 19 slidably connected to one side, and blocks 20 are fixedly connected to the four sides of the base 1. The base 1 has several leakage holes at the top. Through the leakage holes on the base 1, the blocks 20 and the pull-out collection box 19, the excess paint dripping during the spraying process can quickly fall into the collection box 19 through the leakage holes, which is conducive to the centralized treatment of paint waste and environmental management.

[0022] Working Principle: In use, first place the solid wood furniture workpiece to be painted on the placement platform 18 in the center of the base 1. Start the electric push rod 17 to raise the placement platform 18, lifting the workpiece to the predetermined clamping position between the two rotating disks 5. Next, start the reduction motor 13 at one end of the hanger 3, which drives the bidirectional lead screw 14 to rotate. Since the threads at both ends of the bidirectional lead screw 14 are opposite, the two threaded blocks 15 on it will move synchronously towards each other, and through the guidance of the guide rail 16, drive the sliding frames 4 on both sides to smoothly move towards the center, so that the rotating disks 5 on both sides contact the workpiece. Then, start the servo motor 8 inside the rotating disk 5. The servo motor 8 drives the drive disk 9 to rotate, and the fixed lugs 10 on the drive disk 9 pull the slider 7 radially inward along the slide groove 6 via the push rod 11, thereby causing multiple clamping blocks 12 to simultaneously and evenly tighten towards the center from all sides, firmly clamping the workpiece and completing an adaptive, non-destructive, and stable clamping. After clamping, the placement platform 18 descends and resets under the drive of the electric push rod 17, and the workpiece is completely suspended and clamped. At this time, the rotary motor 21 installed on the outside of the sliding frame 4 is started. The rotary motor 21 directly drives the rotating disk 5 and the clamped workpiece through the coupling, so that it begins to rotate at a uniform speed. The spraying equipment is turned on, and the spray gun can perform all-round, uniform, and efficient spraying operation on the uniformly rotating workpiece. During the spraying process, excess paint mist and dripping paint will pass through the drain hole on the base 1 and be blocked by the surrounding blocks 20 before flowing into the slidingly connected collection box 19, which is convenient for centralized cleaning, effectively keeping the working environment clean and recycling waste. After the spraying is completed, the rotary motor 21 stops, and the components operate in reverse order: the placement platform 18 rises again to support the workpiece, the servo motor 8 reverses to release the clamping block 12, the reduction motor 13 reverses to make the sliding frame 4 retract, and finally the sprayed furniture workpiece can be removed.
