Description

Technical Field

[0001] The invention relates to the technical field of hardware processing, in particular to a surface grinding and spraying processing equipment for bathroom hardware. Background Art

[0002] Common bathroom hardware includes towel racks, bath towel racks, faucets, and showers. There are many types of towel racks, including single-pole, double-pole, and multi-pole styles. In order to effectively remove the defects on the surface of the towel rack and improve its surface finish, the surface of the towel rack is usually polished and sprayed.

[0003] For example, the patent with announcement number CN210499527U discloses a surface grinding and spraying processing equipment for bathroom hardware. By setting an adjustment mechanism and a grinding mechanism, the towel rod can be grinded while rotating, and the grinding effect is better.

[0004] However, the above solution can only perform grinding operations on one towel bar at a time, and this feature severely limits the production capacity of the equipment. In the scenario of mass production of towel bars, since only a single workpiece can be processed each time, the overall production cycle will inevitably be greatly lengthened, resulting in a sharp increase in time costs. At the same time, the process of grinding each towel bar in turn requires operators to frequently load and unload workpieces, which increases the frequency of manual intervention. It is not only easy to cause mistakes due to operator fatigue, but also invisibly increases manpower investment. To this end, we proposed a surface grinding and spraying processing equipment for bathroom hardware to effectively solve the above drawbacks. Summary of the invention

[0005] The object of the present invention is to provide a surface grinding and spraying processing equipment for bathroom hardware, which is used to solve the problem that only one towel rod can be polished at a time in the prior art mentioned in the above background technology.

[0006] The present invention is realized by the following technical scheme: a surface grinding and spraying processing equipment for bathroom hardware, comprising a frame, on which a fixed plate and a movable plate are arranged at intervals along the length direction of the frame, the fixed plate is fixed to the frame, and the movable plate can move along the length direction of the frame;

[0007] A plurality of towel bar clamping mechanisms are arranged at intervals along the circumferential direction between the fixed disk and the movable disk, and a synchronous rotation mechanism is installed on the fixed disk to make the towel bar clamping mechanisms rotate synchronously;

[0008] A movable seat capable of moving along the length direction of the frame is arranged on the frame, a bracket is fixed at 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, and a first servo motor for driving the hollow rotating disk to rotate is fixedly installed on the bracket;

[0009] On the outer ring of the hollow rotating disk, there are grinding disks corresponding one by one to each towel rod clamping mechanism. Between two adjacent grinding disks, there are nozzles. Each nozzle is fixed on the outer ring of the hollow rotating disk and communicates with the inner cavity of the hollow rotating disk.

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

[0011] Optionally, a number of legs are fixed to the bottom of the movable disk, and rollers are rotatably connected to the bottom of each leg.

[0012] Optionally, the towel rod clamping mechanism includes a first rotating shaft rotatably connected to the fixed disk. A second rotating shaft corresponding to the first rotating shaft is rotatably connected to the movable disk. Clamps are fixed to both ends of the first rotating shaft and the second rotating shaft that are close to each other.

[0013] Optionally, the synchronous rotation mechanism includes a reduction motor fixedly installed on the frame. The output end of the reduction motor is drivingly connected to a main gear. Sub-gear meshing with the main gear is fixed on each first rotating shaft.

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

[0015] Optionally, four towel rod clamping mechanisms, grinding disks and nozzles are all arranged at equal intervals along the circumferential direction of the rotating disk.

[0016] Optionally, an annular hollow plate located outside each towel clamping mechanism is fixed to the bottom of the moving seat. A number of dust suction openings are provided on the inner ring of the annular hollow plate.

[0017] Optionally, annular baffle plates are fixed to both ends of the annular hollow plate. The ring width of each annular baffle plate is greater than the ring width of the annular hollow plate.

[0018] Optionally, a slag discharge opening is provided at the bottom of the annular hollow plate. A slag receiving box arranged along the length direction of the frame is placed on the frame. The slag receiving box is located below the slag discharge opening.

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

[0020] 1. The present invention, by providing each towel clamping mechanism, moving seat, hollow rotating disk, each grinding disk and each nozzle, in the grinding process, first makes each grinding disk correspond to each towel rod one by one, and then makes the moving seat move to the right, so that the grinding operation can be carried out on multiple towel rods simultaneously by using each grinding disk. Compared with the existing solution of grinding one towel rod in sequence, the grinding time is greatly shortened and the production capacity is greatly improved. After the grinding process is completed, the hollow rotating disk rotates a specific angle to make each nozzle correspond to each towel rod one by one, and then the moving seat moves to the left, and the coating can be sprayed on the surfaces of each towel rod simultaneously.

[0021] The present invention can clamp multiple towel rods at one time and grind and spray multiple towel rods at one time, greatly improving the working efficiency of the equipment, avoiding the operator from frequently loading and unloading single workpieces, reducing the frequency of manual intervention, reducing the probability of errors caused by operation fatigue, and at the same time reducing the labor input, effectively controlling the production cost.

[0022] 2. The present invention, by providing an annular hollow plate, a dust suction port, an annular baffle plate, a slag falling port and a slag receiving box, when grinding the towel rod, the dust suction port and the annular hollow plate cooperate to efficiently suck the dust generated by grinding, so as to effectively purify the air in the working environment, significantly improve the air quality, and create a healthier and safer working space for the operator.

[0023] Moreover, the ash generated during the grinding process can be guided by the annular baffle plate and the annular hollow plate and fall into the slag receiving box through the slag falling port, so as to prevent the ash from scattering everywhere, further avoiding large-area pollution of the workshop floor, preventing it from entering the interior of other equipment, reducing equipment failures and wear caused by ash erosion, and greatly reducing the labor, material and time costs required for daily cleaning and maintenance of the workshop, ensuring that the production operation can continue to run efficiently and stably.

Specific Embodiment

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 5 , a surface grinding and spraying processing device for bathroom hardware, including a frame 1, which provides support for other components in the device. A fixed disk 2 and a movable disk 3 are arranged at intervals along the length direction of the frame 1. The fixed disk 2 is fixed to the frame 1, and the movable disk 3 can move along the length direction of the frame 1. In this embodiment, a cylinder 12 is installed on the frame 1, and the movable end of the cylinder 12 is fixed to the movable disk 3, which is used to push the movable disk 3 to move along the length direction of the frame 1, facilitating the subsequent fixation of towel rods of different lengths. Preferably, a plurality of legs 13 are fixed to the bottom of the movable disk 3, and rollers 14 are rotatably connected to the bottoms of the legs 13. When the movable disk 3 is pushed by the cylinder 12, the movable disk 3 can be supported by the cooperation of the legs 13 and the rollers 14, improving the stability during movement.

[0032] A plurality of towel rod clamping mechanisms 4 are arranged at intervals along the circumferential direction between the fixed disk 2 and the movable disk 3, and a synchronous rotation mechanism 5 for synchronously rotating each towel rod clamping mechanism 4 is installed on the fixed disk 2. In this embodiment, the towel rod clamping mechanism 4 includes a first rotating shaft 401 rotatably connected to the fixed disk 2, a second rotating shaft 402 corresponding to the first rotating shaft 401 is rotatably connected to the movable disk 3, and fixtures 403 are fixed to the ends of the first rotating shaft 401 and the second rotating shaft 402 close to each other, which are used to clamp and fix the towel rod. The cylinder 12 drives the movable disk 3 to move, thereby adjusting the distance between the two fixtures 403, and then different lengths of towel rods can be clamped and fixed by the two fixtures 403.

[0033] The following introduces the synchronous rotation mechanism 5:

[0034] The synchronous rotation mechanism 5 includes a reduction motor 501 fixedly mounted on the frame 1, the output end of the reduction motor 501 is connected to the main gear 502, and each first rotating shaft 401 is fixed with a sub-gear 503 meshing with the main gear 502. When the reduction motor 501 is working, the main gear 502 and the sub-gears 503 cooperate to drive each towel bar clamping mechanism 4 to rotate synchronously and slowly, so that each towel bar rotates synchronously and slowly, which is convenient for subsequent grinding and spraying.

[0035] Here's how to sand and paint multiple towel bars in batches:

[0036] A movable seat 6 capable of moving along the length direction of the frame 1 is provided on the frame 1. In this embodiment, a second servo motor 15 is installed on the frame 1, and a threaded rod 16 is transmission-connected to the output end of the second servo motor 15, and the threaded rod 16 is provided along the length direction of the frame 1 and is threadedly connected to the movable seat 6, and 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 direction of the frame 1 through the cooperation of the threaded rod 16 and the guide rod 17.

[0037] A bracket 7 is fixed at the bottom of the movable seat 6, and 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, which is convenient for grinding and spraying multiple towel rods at the same time. A first servo motor 9 for driving the hollow rotating disk 8 to rotate is fixedly installed on the bracket 7, which is used to drive the hollow rotating disk 8 to rotate a certain angle or rotate a certain angle.

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

[0039] With the above structure, after clamping and fixing multiple towel bars, each towel bar is polished first. In the polishing process, first, each polishing disc 10 is made to correspond to each towel bar one by one, and then the moving seat 6 is moved to the right, so that each towel bar can be polished simultaneously by each polishing disc 10, greatly shortening the polishing time and significantly improving the production capacity. When the polishing process is completed, the hollow rotating disc 8 is rotated by a specific angle so that each nozzle 11 corresponds to each towel bar one by one, and then the moving seat 6 is moved to the left, and the paint can be sprayed onto the surfaces of each towel bar simultaneously, greatly improving the working efficiency of the equipment.

[0040] It is worth mentioning that four towel bar clamping mechanisms 4, polishing discs 10 and nozzles 11 are evenly arranged at equal intervals along the circumferential direction of the rotating disc 8. During the polishing operation, due to the reasonable quantity layout, the ash residues generated and dropped during the polishing process will not have any impact on the towel bars waiting for polishing or already polished below. This not only effectively avoids product quality defects caused by secondary pollution of ash residues, ensures the polishing effect and surface quality of each towel bar, but also greatly improves the coherence and stability of the entire polishing process.

[0041] When polishing the towel bars, not only ash residues will be dropped, but also a large amount of dust will be generated. In order to deal with the ash residues and dust, the following design is specifically carried out:

[0042] A circular hollow plate 18 located outside each towel clamping mechanism 4 is fixed to the bottom of the moving seat 6. The circular hollow plate 18 is connected to an external vacuum cleaner through a hose. A number of dust suction ports 19 are opened on the inner circle of the circular hollow plate 18. Since the circular hollow plate 18 can move synchronously with the moving seat 6, during the polishing of the towel bars, the dust generated during the polishing process can be sucked away through the cooperation of the dust suction ports 19 and the circular hollow plate 18, improving the air quality of the working environment.

[0043] In addition, circular baffle plates 20 are fixed to both ends of the circular hollow plate 18. The ring width of each circular baffle plate 20 is greater than the ring width of the circular hollow plate 18, which is convenient for catching the ash residues dropped during the polishing process. A slag dropping port 21 is opened at the bottom of the circular hollow plate 18. A slag receiving box 22 arranged along the length direction of the machine frame 1 is placed on the machine frame 1, and the slag receiving box 22 is located below the slag dropping port 21. Therefore, during the polishing process, the dropped ash residues will fall into the slag receiving box 22 through the slag dropping port 21 under the guidance of the circular baffle plates 20 and the circular hollow plate 18, which can prevent the ash residues from scattering everywhere and polluting the workshop floor and other equipment, reducing the cleaning and maintenance cost.
