Description

Technical Field

[0001] This invention relates to the field of hardware processing technology, specifically to a surface grinding and spraying processing equipment for bathroom hardware. Background Technology

[0002] Common bathroom hardware includes towel racks, bath towel racks, faucets, and shower heads. Towel racks come in a variety of types, including single, double, and multi-bar styles. To effectively remove surface imperfections and improve the smoothness of the towel rack, surface treatments such as polishing and spraying are typically applied.

[0003] For example, the patent with publication number CN210499527U discloses a surface polishing and spraying processing equipment for bathroom hardware. By setting an adjustment mechanism and a polishing mechanism, it can make the towel bar rotate while polishing, resulting in a better polishing effect.

[0004] However, the aforementioned solution can only perform grinding operations on one towel bar at a time, a characteristic that severely limits the equipment's production capacity. In scenarios involving mass production of towel bars, processing only one workpiece at a time inevitably lengthens the overall production cycle significantly, leading to a sharp increase in time costs. Furthermore, the sequential grinding process for each towel bar requires operators to frequently load and unload workpieces, increasing the frequency of manual intervention. This not only increases the risk of errors due to operator fatigue but also invisibly increases labor costs. Therefore, we propose a surface grinding and spraying processing equipment for bathroom hardware to effectively address these drawbacks. Summary of the Invention

[0005] The purpose of this invention is to provide a surface polishing and spraying processing equipment for bathroom hardware, which solves the problem mentioned in the background art that the existing technology can only perform polishing operations on one towel bar at a time.

[0006] The present invention is achieved through the following technical solution: a surface grinding and spraying processing equipment for bathroom hardware, comprising a frame, wherein fixed plates and movable plates are spaced apart along the length of the frame, the fixed plates are fixed to the frame, and the movable plates are movable along the length of the frame;

[0007] Several towel bar clamping mechanisms are arranged circumferentially between the fixed plate and the movable plate, and a synchronous rotation mechanism is installed on the fixed plate to make each towel bar clamping mechanism rotate synchronously.

[0008] A movable seat capable of moving along the length of the frame is provided on the frame. A bracket is fixed to the bottom of the movable seat. A hollow rotating disk is rotatably connected to the bracket. The hollow rotating disk, the fixed disk, and the movable disk are coaxially arranged. A first servo motor for driving the hollow rotating disk to rotate is fixedly installed on the bracket.

[0009] A polishing disc, corresponding to each towel bar clamping mechanism, is fixed on the outer ring of the hollow rotating disc. A nozzle is provided between two adjacent polishing discs. Each nozzle is fixed on the outer ring of the hollow rotating disc and communicates with the inner cavity of the hollow rotating disc.

[0010] Optionally, a cylinder is installed on the frame, and the movable end of the cylinder is fixed to the movable plate, which is used to push the movable plate to move along the length of the frame.

[0011] Optionally, the bottom of the movable plate is fixed with several legs, and each leg is rotatably connected to a roller.

[0012] Optionally, the towel bar clamping mechanism includes a first rotating shaft rotatably connected to a fixed plate, a second rotating shaft corresponding to the first rotating shaft rotatably connected to a movable plate, and clamps fixed at the ends of the first and second rotating shafts that are close to each other.

[0013] Optionally, the synchronous rotation mechanism includes a geared motor fixedly mounted on the frame, the output end of the geared motor being connected to a main gear, and a secondary gear meshing with the main gear being fixed on each first rotating shaft.

[0014] Optionally, a second servo motor is mounted on the frame, and the output end of the second servo motor is connected to a threaded rod. The threaded rod is arranged along the length of the frame and threadedly connected to the movable seat. A guide rod parallel to the threaded rod and moving through the movable seat is fixed on the frame.

[0015] Optionally, four towel bar clamping mechanisms, grinding discs, and nozzles are arranged at equal intervals along the circumference of the rotating disc.

[0016] Optionally, the bottom of the movable seat is fixed with an annular hollow plate located around each towel clamping mechanism, and several dust suction ports are opened on the inner ring of the annular hollow plate.

[0017] Optionally, annular baffles are fixed at both ends of the annular hollow plate, and the width of each annular baffle is greater than the width of the annular hollow plate.

[0018] Optionally, the bottom of the annular hollow plate is provided with a slag discharge port, and a slag receiving box is placed on the frame along the length of the frame, the slag receiving box being located below the slag discharge port.

[0019] Compared with the prior art, the present invention provides a surface grinding and spraying processing equipment for bathroom hardware, which has the following beneficial effects:

[0020] 1. This invention, by setting up towel clamping mechanisms, a movable base, a hollow rotating disk, grinding discs, and nozzles, allows for simultaneous grinding of multiple towel bars during the grinding process. First, each grinding disc is aligned with a towel bar. Then, the movable base moves to the right, enabling simultaneous grinding of multiple towel bars using the grinding discs. Compared to existing methods that grind one towel bar at a time, this significantly shortens grinding time and greatly increases production capacity. After grinding, the hollow rotating disk rotates at a specific angle, aligning each nozzle with a towel bar. Then, the movable base moves to the left, allowing simultaneous spraying of coating onto the surface of each towel bar.

[0021] This invention can clamp multiple towel bars at once and grind and spray them simultaneously, greatly improving the equipment's working efficiency, avoiding the need for operators to frequently load and unload individual workpieces, reducing the frequency of manual intervention, lowering the probability of errors due to operator fatigue, and also reducing manpower input, effectively controlling production costs.

[0022] 2. By setting up an annular hollow plate, a dust suction port, an annular baffle plate, a slag discharge port, and a slag collection box, the dust suction port and the annular hollow plate work together during the grinding of the towel bar to efficiently remove the dust generated during grinding, thereby effectively purifying the air in the working environment, significantly improving air quality, and creating a healthier and safer working space for operators.

[0023] Furthermore, the ash and slag generated during the grinding process can be guided by the annular baffle plate and the annular hollow plate to fall into the slag collection box through the slag discharge port, thereby preventing the ash and slag from scattering everywhere and thus avoiding large-scale pollution of the workshop floor. It also prevents the ash and slag from entering the interior of other equipment, reducing equipment failures and wear caused by ash and slag erosion. This significantly reduces the manpower, material resources and time costs required for daily cleaning and maintenance of the workshop, ensuring that production operations can continue to operate efficiently and stably.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 5 A surface polishing and spraying processing device for bathroom hardware includes a frame 1, which provides support for other components in the device. Fixed plates 2 and movable plates 3 are spaced apart along the length of the frame 1. The fixed plates 2 are fixed to the frame 1, and the movable plates 3 can move along the length of the frame 1. In this embodiment, a cylinder 12 is installed on the frame 1. The movable end of the cylinder 12 is fixed to the movable plate 3, and is used to push the movable plate 3 to move along the length of the frame 1, facilitating the subsequent fixing of towel bars of different lengths. Preferably, several support legs 13 are fixed to the bottom of the movable plate 3, and rollers 14 are rotatably connected to the bottom of each support leg 13. When the cylinder 12 pushes the movable plate 3, the support legs 13 and rollers 14 provide auxiliary support for the movable plate 3, improving stability during movement.

[0032] A plurality of towel bar clamping mechanisms 4 are arranged circumferentially between the fixed plate 2 and the movable plate 3. A synchronous rotation mechanism 5 is installed on the fixed plate 2 to enable the towel bar clamping mechanisms 4 to rotate synchronously. In this embodiment, the towel bar clamping mechanism 4 includes a first rotating shaft 401 rotatably connected to the fixed plate 2, and a second rotating shaft 402 corresponding to the first rotating shaft 401 rotatably connected to the movable plate 3. Clamps 403 are fixed at the ends of the first rotating shaft 401 and the second rotating shaft 402 that are close to each other, for clamping and fixing the towel bars. The movable plate 3 is moved by the cylinder 12, thereby adjusting the distance between the two clamps 403, so that towel bars of different lengths can be clamped and fixed by the two clamps 403.

[0033] The following is a description of the synchronous rotation mechanism 5:

[0034] The synchronous rotation mechanism 5 includes a geared motor 501 fixedly mounted on the frame 1. The output end of the geared motor 501 is connected to a main gear 502, and a secondary gear 503 that meshes with the main gear 502 is fixed on each of the first rotating shafts 401. When the geared motor 501 is working, the main gear 502 and each secondary gear 503 can drive each towel bar clamping mechanism 4 to rotate synchronously and slowly, thereby making each towel bar rotate synchronously and slowly, which is convenient for subsequent grinding and spraying.

[0035] The following describes how to sand and spray-coat multiple towel bars in batches:

[0036] A movable seat 6, capable of moving along the length of the frame 1, is provided on the frame 1. In this embodiment, a second servo motor 15 is mounted on the frame 1, and a threaded rod 16 is drivenly connected to the output end of the second servo motor 15. The threaded rod 16 is arranged along the length of the frame 1 and threadedly connected to the movable seat 6. A guide rod 17, parallel to the threaded rod 16 and movably passing through the movable seat 6, is fixed on the frame 1. When the second servo motor 15 is working, the movable seat 6 can be driven to move back and forth along the length of the frame 1 through the cooperation of the threaded rod 16 and the guide rod 17.

[0037] A bracket 7 is fixed to the bottom of the movable base 6. A hollow rotating disk 8 is rotatably connected to the bracket 7. The hollow rotating disk 8, the fixed disk 2, and the movable disk 3 are coaxially arranged to facilitate the simultaneous grinding and spraying of multiple towel bars. A first servo motor 9 is fixedly installed on the bracket 7 to drive the hollow rotating disk 8 to rotate or return to its original position by a certain angle.

[0038] A polishing disc 10, corresponding to each towel bar clamping mechanism 4, is fixed on the outer ring of the hollow rotating disk 8. When the polishing disc 10 is opposite to the towel bar, it can polish the towel bar. A nozzle 11 is provided between two adjacent polishing discs 10. Each nozzle 11 is fixed on the outer ring of the hollow rotating disk 8 and communicates with the inner cavity of the hollow rotating disk 8. The hollow rotating disk 8 is connected to an external feed pump through a hose. The feed pump delivers paint to the hollow rotating disk 8, and when the nozzle 11 is opposite to the towel bar, the paint can be sprayed onto the surface of the towel bar.

[0039] Using the above structure, after clamping and fixing multiple towel bars, each towel bar is first polished. During the polishing process, each polishing disc 10 is aligned with each towel bar individually. Then, the moving base 6 is moved to the right, allowing each towel bar to be polished simultaneously by the polishing discs 10, significantly shortening polishing time and greatly increasing production capacity. After the polishing process is completed, the hollow rotating disc 8 is rotated at a specific angle, aligning each nozzle 11 with each towel bar individually. Then, the moving base 6 is moved to the left, allowing paint to be sprayed onto the surface of each towel bar simultaneously, greatly improving the equipment's working efficiency.

[0040] It is worth mentioning that four towel bar clamping mechanisms 4, polishing discs 10, and nozzles 11 are evenly spaced along the circumference of the rotating disc 8. During the polishing process, due to this reasonable arrangement, the dust and slag generated and falling during polishing will not affect the towel bars below that are waiting to be polished or have already been polished. This not only effectively avoids product quality defects caused by secondary contamination from dust and slag, ensuring the polishing effect and surface quality of each towel bar, but also greatly improves the consistency and stability of the entire polishing process.

[0041] When sanding towel bars, not only will ash and debris fall off, but a large amount of dust will also be generated. In order to deal with the ash and dust, the following design is proposed:

[0042] The bottom of the movable base 6 is fixed with an annular hollow plate 18 located around each towel clamping mechanism 4. The annular hollow plate 18 is connected to an external vacuum cleaner via a flexible hose. Several suction ports 19 are provided on the inner ring of the annular hollow plate 18. Since the annular hollow plate 18 can move synchronously with the movable base 6, when polishing the towel bar, the dust generated during the polishing process can be sucked away through the cooperation of the suction ports 19 and the annular hollow plate 18, thus improving the air quality of the working environment.

[0043] In addition, annular baffles 20 are fixed at both ends of the annular hollow plate 18. The width of each annular baffle 20 is greater than the width of the annular hollow plate 18, which facilitates the collection of ash and slag falling during the grinding process. A slag discharge port 21 is provided at the bottom of the annular hollow plate 18. A slag receiving box 22 is placed on the frame 1 along the length of the frame 1, and the slag receiving box 22 is located below the slag discharge port 21. Therefore, during the grinding process, the falling ash and slag will be guided by the annular baffles 20 and the annular hollow plate 18, and fall into the slag receiving box 22 through the slag discharge port 21, which can prevent the ash and slag from scattering everywhere and causing pollution to the workshop floor and other equipment, and reduce cleaning and maintenance costs.
